Alice Doherty; Kathy Conklin How gender-expectancy affects the processing of “them” Journal Article In: Quarterly Journal of Experimental Psychology, vol. 70, no. 4, pp. 718–735, 2017. @article{Doherty2017, How sensitive is pronoun processing to expectancies based on real-world knowledge and language usage? The current study links research on the integration of gender stereotypes and number-mismatch to explore this question. It focuses on the use of them to refer to antecedents of different levels of gender-expectancy (low-cyclist, high-mechanic, known-spokeswoman). In a rating task, them is considered increasingly unnatural with greater gender-expectancy. However, participants might not be able to differentiate high-expectancy and gender-known antecedents online because they initially search for plural antecedents (e.g., Sanford & Filik), and they make all-or-nothing gender inferences. An eye-tracking study reveals early differences in the processing of them with antecedents of high gender-expectancy compared with gender-known antecedents. This suggests that participants have rapid access to the expected gender of the antecedent and the level of that expectancy. |
Denis Drieghe; Lei Cui; Guoli Yan; Bai Xuejun; Chi Hui; Simon P. Liversedge The morphosyntactic structure of compound words influences parafoveal processing in Chinese reading Journal Article In: Quarterly Journal of Experimental Psychology, vol. 71, no. 1, pp. 190–197, 2017. @article{Drieghe2017a, In an eye movement experiment employing the boundary paradigm, we compared parafoveal preview benefit during the reading of Chinese sentences. The target word was a two-character compound that had either a noun–noun or an adjective–noun structure each sharing an identical noun as the second character. The boundary was located between the two characters of the compound word. Prior to the eyes crossing the boundary, the preview of the second character was presented either normally or was replaced by a pseudocharacter. Previously, Juhasz, Inhoff, and Rayner observed that inserting a space into a normally unspaced compound in English significantly disrupted processing and that this disruption was larger for adjective–noun compounds than for noun–noun compounds. This finding supports the hypothesis that, at least in English, for adjective–noun compounds, the noun is more important for lexical identification than the adjective, while for noun–noun compounds, both constituents are similar in importance for lexical identification. Our results indicate a similar division of the importance of compounds in reading in Chinese as the pseudocharacter preview was more disruptive for the adjective–noun compounds than for the noun–noun compounds. These findings also indicate that parafoveal processing can be influenced by the morphosyntactic structure of the currently fixated character. |
Denis Drieghe; Gemma Fitzsimmons; Simon P. Liversedge Parafoveal preview effects in reading unspaced text Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 43, no. 10, pp. 1701–1716, 2017. @article{Drieghe2017, In English reading, eye guidance relies heavily on the spaces between words for demarcating word boundaries. In an eye tracking experiment, we examined the impact of removing spaces on parafoveal processing. Using the gaze-contingent boundary paradigm (Rayner, 1975), a high or low frequency preboundary word was followed by a postboundary preview presented either normally (i.e., identical to the postboundary word), or with letters replaced creating an orthographically illegal preview. The spaces between words were either retained or removed. Results replicate previous findings of increased reading times during unspaced reading (Rayner, Fischer, & Pollatsek, 1998) and indicate rather limited evidence for more distributed processing: Observations of processing of the previous word (spill-over effects) or processing of the next word (parafoveal-on-foveal effects) influencing fixation durations on the currently fixated word were limited. Spill-over effects were only observed in the unspaced layout when the postboundary preview was correct, presumably because the orthographically illegal, incorrect preview was visually salient enough to allow for relatively easy word segmentation and therefore more focused processing of the preboundary word. As such, results points toward a system that prefers narrowly focused processing of a single word, at least when means for easy word segmentation are available. |
Mareike Bayer; Katja Ruthmann; Annekathrin Schacht The impact of personal relevance on emotion processing: Evidence from event-related potentials and pupillary responses Journal Article In: Social Cognitive and Affective Neuroscience, vol. 12, no. 9, pp. 1470–1479, 2017. @article{Bayer2017, Emotional stimuli attract attention and lead to increased activity in the visual cortex. The present study investigated the impact of personal relevance on emotion processing by presenting emotional words within sentences that referred to participants' significant others or to unknown agents. In event-related potentials, personal relevance increased visual cortex activity within 100 ms after stimulus onset and the amplitudes of the Late Positive Complex (LPC). Moreover, personally relevant contexts gave rise to augmented pupillary responses and higher arousal ratings, suggesting a general boost of attention and arousal. Finally, personal relevance increased emotion-related ERP effects starting around 200 ms after word onset; effects for negative words compared to neutral words were prolonged in duration. Source localizations of these interactions revealed activations in prefrontal regions, in the visual cortex and in the fusiform gyrus. Taken together, these results demonstrate the high impact of personal relevance on reading in general and on emotion processing in particular. |
Elika Bergelson; Richard N. Aslin Nature and origins of the lexicon in 6-mo-olds Journal Article In: Proceedings of the National Academy of Sciences, vol. 114, no. 49, pp. 12916–12921, 2017. @article{Bergelson2017, Recent research reported the surprising finding that even 6-mo-olds understand common nouns [Bergelson E, Swingley D (2012) Proc Natl Acad Sci USA 109:3253-3258]. However, is their early lexicon structured and acquired like older learners? We test 6-mo-olds for a hallmark of the mature lexicon: cross-word relations. We also examine whether properties of the home environment that have been linked with lexical knowledge in older children are detectable in the initial stage of comprehension. We use a new dataset, which includes in-lab comprehension and home measures from the same infants. We find evidence for cross-word structure: On seeing two images of common nouns, infants looked significantly more at named target images when the competitor images were semantically unrelated (e.g., milk and foot) than when they were related (e.g., milk and juice), just as older learners do. We further find initial evidence for home-lab links: common noun "copresence" (i.e., whether words' referents were present and attended to in home recordings) correlated with in-lab comprehension. These findings suggest that, even in neophyte word learners, cross-word relations are formed early and the home learning environment measurably helps shape the lexicon from the outset. |
Frank Boers; Paul A. Warren; Gina M. Grimshaw; Anna Siyanova-Chanturia On the benefits of multimodal annotations for vocabulary uptake from reading Journal Article In: Computer Assisted Language Learning, vol. 30, no. 7, pp. 709–725, 2017. @article{Boers2017, Several research articles published in the realm of Computer Assisted Language Learning (CALL) have reported evidence of the benefits of multimodal annotations, i.e. the provision of pictorial as well as verbal clarifications, for vocabulary uptake from reading. Almost invariably, these publications account for the observed benefits with reference to Paivio's Dual Coding Theory, suggesting it is the visual illustration of word meaning that enhances the quality of processing and hence makes new words more memorable. In this discussion article, we explore the possibility that it is not necessarily the multimodality per se that accounts for the reported benefits. Instead, we argue that the provision of multimodal annotations is one of several possible means of inviting more and/or longer attention to the annotations – with amounts of attention given to words being a significant predictor of their retention in memory. After reviewing the available research on the subject and questioning whether invoking Paivio's Dual Coding Theory is an optimal account for reported findings, we report an eye-tracking study the results of which are consistent with the alternative thesis that the advantage of multimodal glosses for word learning lies with the greater quantity of attention these glosses attract in comparison with single-mode glosses. We conclude with a call for further research on combinations and sequences of annotation types, regardless of multimodality, as ways of promoting vocabulary uptake from reading. |
Arielle Borovsky The amount and structure of prior event experience affects anticipatory sentence interpretation Journal Article In: Language, Cognition and Neuroscience, vol. 32, no. 2, pp. 190–204, 2017. @article{Borovsky2017, Listeners easily interpret speech about novel events in everyday conversation; however, much of research on mechanisms of spoken language comprehension, by design, capitalises on event knowledge that is familiar to most listeners. This paper explores how listeners generalise from previous experience during incremental processing of novel spoken sentences. In two studies, participants initially heard stories that conveyed novel event mappings between agents, actions and objects, and their ability to interpret a novel, related event in real-time was measured via eye-tracking. A single exposure to a novel event was not sufficient to support generalisation in real-time sentence processing. When each story event was repeated with either the same agent or a different, related agent, listeners generalised in the repetition condition, but not in the multiple agent condition. These findings shed light on the conditions under which listeners leverage prior event experience while interpreting novel linguistic signals in everyday speech. |
Oliver Boxell; Claudia Felser Sensitivity to parasitic gaps inside subject islands in native and non-native sentence processing Journal Article In: Bilingualism, vol. 20, no. 3, pp. 494–511, 2017. @article{Boxell2017, We report the results from an eye-movement monitoring study that investigated late German-English bilinguals' sensitivity to parasitic gaps inside subject islands. The online reading experiment was complemented by an offline scalar judgement task. The results from the offline task confirmed that for both native and non-native speakers, subject island environments must normally be non-finite in order to host a parasitic gap. The analysis of the reading-time data showed that, while native speakers posited parasitic gaps in non-finite environments only, the non-native group initially overgenerated parasitic gaps, showing delayed sensitivity to island-inducing cues during online processing. Taken together, our findings show that non-native comprehenders are sensitive to exceptions to island constraints that are not attested in their native language and also rare in the L2 input. They need more time than native comprehenders to compute the linguistic representations over which the relevant restrictions are defined, however. |
Oliver Boxell; Claudia Felser; Ian Cunnings Antecedent contained deletions in native and non-native sentence processing Journal Article In: Linguistic Approaches to Bilingualism, vol. 7, no. 5, pp. 554–582, 2017. @article{Boxell2017a, We report the results from an eye-movement monitoring study investigating native (L1) and non-native (L2) speakers' real-time processing of antecedent-contained deletion (ACD), a type of verb phrase ellipsis in which the ellipsis gap forms part of its own antecedent. The resulting interpretation problem is traditionally thought to be solved by quantifier raising, a covert scope-shifting operation that serves to remove the gap from within its antecedent. Our L2 group comprised advanced, native German-speaking L2 learners of English. The analysis of the eye-movement data showed that both L1 and L2 English speakers tried to recover the missing verb phrase after encountering the gap. Only the native speakers showed evidence of ellipsis resolution being affected by quantification, however. No effects of quantification following gap detection were found in the L2 group, by contrast, indicating that recovery of the elided material was accomplished independently from the object's quantificational status in this group. |
Trevor Brothers; Liv J. Hoversten; Matthew J. Traxler Looking back on reading ahead: No evidence for lexical parafoveal-on-foveal effects Journal Article In: Journal of Memory and Language, vol. 96, pp. 9–22, 2017. @article{Brothers2017, Current models of eye movement control during reading make different predictions regarding the possibility of parafoveal-on-foveal effects – i.e. whether the lexical properties of upcoming, parafoveal words can affect reading time. To date, there have been contradictory findings from correlational corpus analyses and carefully controlled experimental studies regarding the existence of these effects. To address this controversy, we conducted four experimental studies (total N = 244) investigating the effects of parafoveal word frequency during natural reading. These experiments showed no evidence for parafoveal-on-foveal effects in an environment that should have been highly conducive to parallel lexical processing. In addition, a Bayes Factor meta-analysis of the prior experimental literature also provided clear support for the null hypothesis. These findings confirm the predictions of serial attention models such as E-Z Reader, and call into question the findings of previous correlational corpus studies. |
Sarah Brown-Schmidt; Joseph C. Toscano Gradient acoustic information induces long-lasting referential uncertainty in short discourses Journal Article In: Language, Cognition and Neuroscience, vol. 32, no. 10, pp. 1211–1228, 2017. @article{BrownSchmidt2017, Three experiments examined the influence of gradient acoustic information on referential interpretation during spoken language processing and how this influence persists over time. Acoustic continua varying between the pronouns “he” and “she” were created and validated in two offline experiments. A third experiment examined whether these acoustic differences influence online pronoun interpretation, and whether this influence persists across words in a discourse. Measures of eye gaze showed immediate sensitivity to graded acoustic information. Moreover, acoustically induced uncertainty persisted across a five-word delay: When listeners encountered a word that disambiguated the referent of the pronoun differently than it had originally been interpreted, the amount of time they took to recover from an initial misinterpretation was directly related to distance along the acoustic continuum between the pronoun and the endpoint corresponding to the correct referent.These findings show that fine-grained acoustic detail induces referential uncertainty that is maintained over extended periods of time. |
Yulia Esaulova; Chiara Reali; Lisa Stockhausen Prominence of gender cues in the assignment of thematic roles in German Journal Article In: Applied Psycholinguistics, vol. 38, no. 5, pp. 1133–1172, 2017. @article{Esaulova2017, Two eye-tracking experiments examined influences of grammatical and stereotypical gender cues on the assignment of thematic roles in German. Participants (N 1 = 32, N 2 = 40) read sentences with subject- and object-extracted relative clauses, where thematic agents and patients remained ambiguous until the end of the relative clause. The results reveal a linguistic gender bias: agent roles are assigned more easily to grammatically masculine than feminine role nouns and stereotypically neutral than female ones. The opposite pattern is observed in the assignment of patient roles for stereotypical but not grammatical gender. The findings are discussed within the framework of situation model theories as well as in constraint-based and similarity-based interference accounts, while gender is viewed as a dimension of prominence. |
Michael A. Eskenazi; Jocelyn R. Folk Regressions during reading: The cost depends on the cause Journal Article In: Psychonomic Bulletin & Review, vol. 24, no. 4, pp. 1211–1216, 2017. @article{Eskenazi2017, The direction and duration of eye movements during reading is predominantly determined by cognitive and linguistic processing, but some low-level oculomotor effects also influence the duration and direction of eye movements. One such effect is inhibition of return (IOR), which results in an increased latency to return attention to a target that has been previously attended (Posner & Cohen, Attention and Performance X: Control of Language Processes, 32, 531– 556, 1984). Although this is a low level effect, it has also been found in the complex task of reading (Henderson & Luke, Psychonomic Bulletin & Review, 19(6), 1101–1107, 2012; Rayner, Juhasz, Ashby, & Clifton, Vision Research, 43(9), 1027–1034, 2003). The purpose of the current study was to isolate the potentially different causes ofregressive eye movements: to adjust for oculomotor error and to assist with comprehension difficulties. We found that readers demonstrated an IOR effect when regressions were caused by oculomotor error, but not when regressions were caused by comprehension difficulties. The results suggest that IOR is primarily associated with low-level oculomotor control of eye movements, and that regressive eye movements that are controlled by comprehension processes are not subject to IOR effects. The results have implications for understanding the relationship between oculomotor and cognitive control ofeye movements and for models ofeye movement control. |
Claudia Felser; Janna Deborah Drummer Sensitivity to crossover constraints during native and non-native pronoun resolution Journal Article In: Journal of Psycholinguistic Research, vol. 46, no. 3, pp. 771–789, 2017. @article{Felser2017, We report the results from two experiments examining native and non-native Ger-man speakers' sensitivity to crossover constraints on pronoun resolution. Our critical stimuli sentences contained personal pronouns in either strong (SCO) or weak crossover (WCO) configurations. Using eye-movement monitoring during reading and a gender-mismatch par-adigm, Experiment 1 investigated whether a fronted wh-phrase would be considered as a potential antecedent for a pronoun intervening between the wh-phrase and its canonical position. Both native and non-native readers initially attempted coreference in WCO but not in SCO configurations, as evidenced by early gender-mismatch effects in our WCO conditions. Experiment 2 was an offline antecedent judgement task whose results mirrored the SCO/WCO asymmetry observed in our reading-time data. Taken together, our results show that the SCO constraint immediately restricts pronoun interpretation in both native and non-native comprehension, and further suggest that SCO and WCO constraints derive from different sources. |
Evelyn C. Ferstl; Laura Israel; Lisa Putzar Humor facilitates text comprehension: Evidence from eye movements Journal Article In: Discourse Processes, vol. 54, no. 4, pp. 259–284, 2017. @article{Ferstl2017, One crucial property of verbal jokes is that the punchline usually contains an incongruency that has to be resolved by updating the situation model representation. In the standard pragmatic model, these processes are considered to require cognitive effort. However, only few studies compared jokes to texts requiring a situation model revision without being funny. In the present study participants' eye movements were recorded while they read short texts falling into four categories: jokes, texts that made a revision of the situation model necessary without being funny (revision texts), and two types of control texts. Jokes were read faster and elicited fewer regressive eye movements than the other text categories. Women were more sensitive to revision and inference demands of nonhumorous texts than men, and this was particularly the case when the instructions required a meta-linguistic evaluation. In contrast to the predictions of the two-stage model of pragmatics, humor appreciation facilitated text comprehension, and this effect was more pronounced for men than for women. |
Ruth Filik; Emily Brightman; Chloe Gathercole; Hartmut Leuthold The emotional impact of verbal irony: Eye-tracking evidence for a two-stage process Journal Article In: Journal of Memory and Language, vol. 93, pp. 193–202, 2017. @article{Filik2017, In this paper we investigate the socio-emotional functions of verbal irony. Specifically, we use eye-tracking while reading to assess moment-to-moment processing of a character's emotional response to ironic versus literal criticism. In Experiment 1, participants read stories describing a character being upset following criticism from another character. Results showed that participants initially more easily integrated a hurt response following ironic criticism; but later found it easier to integrate a hurt response following literal criticism. In Experiment 2, characters were instead described as having an amused response, which participants ultimately integrated more easily following ironic criticism. From this we propose a two-stage process of emotional responding to irony: While readers may initially expect a character to be more hurt by ironic than literal criticism, they ultimately rationalize ironic criticism as being less hurtful, and more amusing. |
Francesca Foppolo; Marco Marelli No delay for some inferences Journal Article In: Journal of Semantics, vol. 34, no. 4, pp. 659–681, 2017. @article{Foppolo2017, We present an eye-tracking study on the incremental derivation of the some-but not- all scalar implicature (SI) associated to the scalar quantifier some. This question has been the matter of a vivid debate, both in linguistics and in psycholinguistics (Chemla & Singh 2014a,b). Experimentally, it was addressed by means of eyetracking and different results were obtained: while Huang & Snedeker (2009) found evidence for a delay of some with respect to all, Grodner et al. (2010) argued for a rapid integration of pragmatic some. More recently, Breheny et al. (2013a,b) raised some criticism on the paradigm employed in those studies and contributed with a looking-while-listening task showing incremental derivation of the scalar inference. We first raise some methodological questions, arguing that the paradigm used in previous studies was not apt to distinguish whether a scalar inference was derived or not, for different reasons. By means of a novel visual-world eye-tracking experiment in which we exploit the notion of focus in the activation of scalar alternatives, we show new evidence for the incremental derivation of the pragmatic some-but not- all interpretation of some. We interpret these results within a grammatical approach to SIs (Chierchia et al. 2012; Chierchia 2013), according to which, when scalar alternatives are active, the SI is factored in locally and incrementally during the online processing of the scalar quantifier. |
Steven Frisson; David R. Harvey; Adrian Staub No prediction error cost in reading: Evidence from eye movements Journal Article In: Journal of Memory and Language, vol. 95, pp. 200–214, 2017. @article{Frisson2017, Two eye movement while reading experiments address the issue of how reading of an unpredictable word is influenced by the presence of a more predictable alternative. The experiments replicate the robust effects of predictability on the probability of skipping and on early and late reading time measures. However, in both experiments, an unpredictable but plausible word was read no more slowly when another word was highly predictable (i.e., in a constraining context) than when no word was highly predictable (i.e., in a neutral context). In fact, an unpredictable word that was semantically related to the predictable alternative demonstrated facilitation in the constraining context, in relatively late eye movement measures. These results, which are consistent with Luke and Christianson's (2016) corpus study, provide the first evidence from a controlled experimental design for the absence of a prediction error cost, and for facilitation of an unpredictable but semantically related word, during normal reading. The findings support a model of lexical predictability effects in which there is broad pre-activation of potential continuations, rather than discrete predictions of specific lexical items. Importantly, pre-activation of likely continuations does not result in processing difficulty when some other word is actually encountered. |
Kumiko Fukumura; Roger P. G. Gompel How do violations of Gricean maxims affect reading? Journal Article In: Journal of Memory and Language, vol. 95, pp. 1–18, 2017. @article{Fukumura2017, Four eye-tracking experiments examined how violations of the Gricean maxim of quantity affect reading. Experiments 1 and 2 showed that first-pass reading times for size-modified definite nouns (the small towel) were longer when the modifier was redundant, as the context contained one rather than two possible referents, whereas first-pass times for bare nouns (the towel) were unaffected by whether the context contained multiple referents that resulted in ambiguity. Experiment 3 showed that unlike redundant size modifiers, redundant color modifiers did not increase first-pass times. Experiment 4 confirmed this finding, demonstrating that the effect of redundancy was dependent on the meaning of the modifier. We propose that initial referential processing is led by the lexico-semantic representation of the referring expression rather than Gricean expectations about optimal informativeness: Redundancy of a size-modifier immediately disrupts comprehension because the processor fails to activate the referential contrast implied by the meaning of the modifier, whereas referential ambiguity has no immediate effect, as it allows the activation of at least one semantically-compatible referent. |
Lesya Y. Ganushchak; Agnieszka E. Konopka; Yiya Chen Accessibility of referent information influences sentence planning: An eye-tracking study Journal Article In: Frontiers in Psychology, vol. 8, pp. 250, 2017. @article{Ganushchak2017, This study investigated the time-course of online sentence formulation (i.e., incrementality in sentence planning) as a function of the preceding discourse context. In two eye-tracking experiments, participants described pictures of transitive events (e.g., a frog catching a fly). The accessibility of the agent (Experiment 1) and patient (Experiment 2) was manipulated in the discourse preceding each picture. In the Literal condition, participants heard a story where the agent or patient was mentioned explicitly (fly, frog). In the Associative condition, the agent or patient was not mentioned but was primed by the story (via semantically or associatively related words such as insect, small, black, wings). In the No Mention condition, the stories did not explicitly mention or prime either character. The target response was expected to have the same structure and content in all conditions (SVO sentences: The frog catches the fly). The results showed that participants generally looked first at the agent, before speech onset, regardless of condition, and then at the patient around and after speech onset. Analyses of eye movements in time window associated with linguistic planning showed that formulation was sensitive mainly to whether the agent was literally mentioned in the context or not and to lesser extent to conceptual accessibility (Experiment 1). Furthermore, accessibility of the patient (be it literal mention of its name or only availability of the concept) showed no effect on the time-course of utterance planning (Experiment 2). Together, these results suggest that linguistic planning before speech onset was influenced only by the accessibility of the first character name in the sentence, providing further evidence for highly incremental planning in sentence production. |
Daniel J. Acheson; Peter Hagoort Stimulating the brainʼs language network: Syntactic ambiguity resolution after TMS to the inferior frontal gyrus and middle temporal gyrus Journal Article In: Journal of Cognitive Neuroscience, vol. 25, no. 10, pp. 1664–1677, 2017. @article{Acheson2017, The posterior middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) are two critical nodes of the brainʼs language network. Previous neuroimaging evidence has supported a dis- sociation in language comprehension in which parts of the MTG are involved in the retrieval of lexical syntactic informa- tion and the IFG in unification operations that maintain, select, and integrate multiple sources of information over time. In the present investigation, we tested for causal evidence of this dis- sociation by modulating activity in IFG and MTG using an off- line TMS procedure: continuous theta-burst stimulation. Lexical–syntactic retrieval was manipulated by using sentences with and without a temporarily word-class (noun/verb) ambiguity (e.g., run). In one group of participants, TMS was applied to the IFG and MTG, and in a control group, no TMS was applied. Eye movements were recorded and quantified at two critical sentence regions: a temporarily ambiguous region and a disambig- uating region. Results show that stimulation of the IFG led to a modulation of the ambiguity effect (ambiguous–unambiguous) at the disambiguating sentence region in three measures: first fixation durations, total reading times, and regressive eye movements into the region. Both IFG and MTG stimulation modulated the ambiguity effect for total reading times in the temporarily ambiguous sentence region relative to the control group. The current results demonstrate that an offline repetitive TMS protocol can have influences at a different point in time during online processing and provide causal evidence for IFG involvement in unification operations during sentence comprehension. |
Carlos Aguilar; Eric Castet Evaluation of a gaze-controlled vision enhancement system for reading in visually impaired people Journal Article In: PLoS ONE, vol. 12, no. 4, pp. e0174910, 2017. @article{Aguilar2017, People with low vision, especially those with Central Field Loss (CFL), need magnification to read. The flexibility of Electronic Vision Enhancement Systems (EVES) offers several ways of magnifying text. Due to the restricted field of view of EVES, the need for magnification is conflicting with the need to navigate through text (panning). We have developed and implemented a real-time gaze-controlled system whose goal is to optimize the possibility of magnifying a portion of text while maintaining global viewing of the other portions of the text (condition 1). Two other conditions were implemented that mimicked commercially available advanced systems known as CCTV (closed-circuit television systems)-conditions 2 and 3. In these two conditions, magnification was uniformly applied to the whole text without any possibility to specifically select a region of interest. The three conditions were implemented on the same computer to remove differences that might have been induced by dissimilar equipment. A gaze-contingent artificial 10° scotoma (a mask continuously displayed in real time on the screen at the gaze location) was used in the three conditions in order to simulate macular degeneration. Ten healthy subjects with a gaze-contingent scotoma read aloud sentences from a French newspaper in nine experimental one-hour sessions. Reading speed was measured and constituted the main dependent variable to compare the three conditions. All subjects were able to use condition 1 and they found it slightly more comfortable to use than condition 2 (and similar to condition 3). Importantly, reading speed results did not show any significant difference between the three systems. In addition, learning curves were similar in the three conditions. This proof of concept study suggests that the principles underlying the gaze-controlled enhanced system might be further developed and fruitfully incorporated in different kinds of EVES for low vision reading. |
Noor Z. Al Dahhan; John R. Kirby; Donald C. Brien; Douglas P. Munoz Eye movements and articulations during a letter naming speed task: Children with and without Dyslexia Journal Article In: Journal of Learning Disabilities, vol. 50, no. 3, pp. 275–285, 2017. @article{AlDahhan2017, Abstract Naming speed (NS) refers to how quickly and accurately participants name a set of familiar stimuli (e.g., letters). NS is an established predictor of reading ability, but controversy remains over why it is related to reading. We used three techniques (stimulus manipulations to emphasize phonological and/or visual aspects, decomposition of NS times into pause and articulation components, and analysis of eye movements during task performance) with three groups of participants (children with dyslexia, ages 9–10; chronological-age [CA] controls, ages 9–10; reading-level [RL] controls, ages 6–7) to examine NS and the NS–reading relationship. Results indicated (a) for all groups, increasing visual similarity of the letters decreased letter naming efficiency and increased naming errors, saccades, regressions (rapid eye movements back to letters already fixated), pause times, and fixation durations; (b) children with dyslexia performed like RL controls and were less efficient, had longer articulation times, pause times, fixation durations, and made more errors and regressions than CA controls; and (c) pause time and fixation duration were the most powerful predictors of reading. We conclude that NS is related to reading via fixation durations and pause times: Longer fixation durations and pause times reflect the greater amount of time needed to acquire visual/orthographic information from stimuli and prepare the correct response. |
Noor Al-Zanoon; Michael Dambacher; Victor Kuperman Evidence for a global oculomotor program in reading Journal Article In: Psychological Research, vol. 81, no. 4, pp. 863–877, 2017. @article{AlZanoon2017, Recent corpus studies of eye-movements in reading revealed a substantial increase in saccade amplitudes and fixation durations as the eyes move over the first words of a sentence. This start-up effect suggests a global oculomotor program, which operates on the level of an entire line, in addition to the well-established local programs operating within the visual span. The present study investigates the nature of this global program experimentally and examines whether the start-up effect is predicated on generic visual or specific linguistic characteristics and whether it is mainly reflected in saccade amplitudes, fixation durations or both measures. Eye movements were recorded while 38 participants read (a) normal sentences, (b) sequences of randomly shuffled words and (c) sequences of z-strings. The stimuli were, therefore, similar in their visual features, but varied in the amount of syntactic and lexical information. Further, the stimuli were composed of words or strings that either varied naturally in length (Nonequal condition) or were all restricted to a specific length within a sentence (Equal). The latter condition constrained the variability of saccades and served to dissociate effects of word position in line on saccade amplitudes and fixation durations. A robust start-up effect emerged in saccade amplitudes in all Nonequal stimuli, and-in an attenuated form-in Equal sentences. A start-up effect in single fixation durations was observed in Nonequal and Equal normal sentences, but not in z-strings. These findings support the notion of a global oculomotor program in reading particularly for the spatial characteristics of motor planning, which rely on visual rather than linguistic information. |
Nathan Arnett; Matthew Wagers Subject encodings and retrieval interference Journal Article In: Journal of Memory and Language, vol. 93, pp. 22–54, 2017. @article{Arnett2017, Interference has been identified as a cause of processing difficulty in linguistic dependencies, such as the subject-verb relation (Van Dyke and Lewis, 2003). However, while mounting evidence implicates retrieval interference in sentence processing, the nature of the retrieval cues involved - and thus the source of difficulty - remains largely unexplored. Three experiments used self-paced reading and eyetracking to examine the ways in which the retrieval cues provided at a verb characterize subjects. Syntactic theory has identified a number of properties correlated with subjecthood, both phrase-structural and thematic. Findings replicate and extend previous findings of interference at a verb from additional subjects, but indicate that retrieval outcomes are relativized to the syntactic domain in which the retrieval occurs. One, the cues distinguish between thematic subjects in verbal and nominal domains. Two, within the verbal domain, retrieval is sensitive to abstract syntactic properties associated with subjects and their clauses. We argue that the processing at a verb requires cue-driven retrieval, and that the retrieval cues utilize abstract grammatical properties which may reflect parser expectations. |
Laura Winther Balling; Johannes Kizach Effects of surprisal and locality on Danish sentence processing: An eye-tracking investigation Journal Article In: Journal of Psycholinguistic Research, vol. 46, no. 5, pp. 1119–1136, 2017. @article{Balling2017, An eye-tracking experiment in Danish investigates two dominant accounts of sentence processing: locality-based theories that predict a processing advantage for sentences where the distance between the major syntactic heads is minimized, and the surprisal theory which predicts that processing time increases with big changes in the relative entropy of possible parses, sometimes leading to anti-locality effects. We consider both lexicalised surprisal, expressed in conditional trigram probabilities, and syntactic surprisal expressed in the manipulation of the expectedness of the second NP in Danish constructions with two postverbal NP-objects. An eye-tracking experiment showed a clear advantage for local syntactic relations, with only a marginal effect of lexicalised surprisal and no effect of syntactic surprisal. We conclude that surprisal has a relatively marginal effect, which may be clearest for verbs in verb-final languages, while locality is a robust predictor of sentence processing. |

In particular, inefficient shifting of visual attention during spatial cueing paradigms is assumed to be associated with problems in graphemic parsing during sublexical reading. The current study investigated visuo-spatial attention performance in an exogenous cueing paradigm in a large sample (N = 191) of third and fourth graders with different reading and spelling profiles (controls, isolated reading deficit, isolated spelling deficit, combined deficit in reading and spelling). Once individual variability in reaction times was taken into account by means of z-transformation, a cueing deficit (i.e. no significant difference between valid and invalid trials) was found for children with combined deficits in reading and spelling. However, poor readers without spelling problems showed a cueing effect comparable to controls, but exhibited a particularly strong right-over-left advantage (position effect). Isolated poor spellers showed a significant cueing effect, but no position effect. While we replicated earlier findings of a reduced cueing effect among poor nonword readers (indicating deficits in sublexical processing), we also found a reduced cueing effect among children with particularly poor orthographic spelling (indicating deficits in lexical processing). Thus, earlier claims of a specific association with nonword reading could not be confirmed. Controlling for ADHD-symptoms reported in a parental questionnaire did not impact on the statistical analysis, indicating that cueing deficits are not caused by more general attentional limitations. Between 31 and 48% of participants in the three reading and/or spelling deficit groups as well as 32% of the control group showed reduced spatial cueing. These findings indicate a significant, but moderate association between certain aspects of visuo-spatial attention and subcomponents of written language processing, the causal status of which is yet unclear. |

Previous research has reported on reading component skills for students in adult education settings, but little is known about eye movement patterns or their relation to reading skills for this population. In this study, reading component skills including decoding, language comprehension, and reading fluency are reported, as are eye movement variables for connected-text oral reading. Eye movement comparisons between individuals with higher and lower oral reading fluency revealed within- and between-subject effects for word frequency and word length as well as group and word frequency interactions. Bivariate correlations indicated strong relations between component skills of reading, eye movement measures, and both the Test of Adult Basic Education (Reading subtest) and the Woodcock-Johnson III Diagnostic Reading Battery Passage Comprehension assessments. Regression analyses revealed the utility of decoding, language comprehension, and lexical activation time for predicting achievement on both the Woodcock Johnson III Passage Comprehension and the Test of Adult Basic Education Reading Comprehension. |

Korean uses a different word (i.e., netha) for loose-fits (e.g., apple in bowl). We tested whether these differences influence the attention of the speaker. In a crosslinguistic study, we compared native German speakers with native Korean speakers. Participants rated the similarity of two successive video clips of several scenes where two objects were joined or nested (either in a tight or loose manner). The rating data show that Korean speakers base their rating of similarity more on tight-versus loose-fit, whereas German speakers base their rating more on containment versus support (in vs. auf). Throughout the experiment, we also measured the participants' eye movements. Korean speakers looked equally long at the moving Figure object and at the stationary Ground object, whereas German speakers were more biased to look at the Ground object. Additionally, Korean speakers also looked more at the region where the two objects touched than did German speakers. We discuss our data in the light of crosslinguistic semantics and the extent of their influence on spatial cognition and perception. |
Axel Grzymisch; Cathleen Grimsen; Udo A. Ernst Contour integration in dynamic scenes: Impaired detection performance in extended presentations Journal Article In: Frontiers in Psychology, vol. 8, pp. 1501, 2017. @article{Grzymisch2017, Since scenes in nature are highly dynamic, perception requires an on-going and robust 5 integration of local information into global representations. In vision, contour integration (CI) 6 is one of these tasks, and it is performed by our brain in a seemingly effortless manner. 7 Following the rule of good continuation, oriented line segments are linked into contour percepts, 8 thus supporting important visual computations such as the detection of object boundaries. 9 This process has been studied almost exclusively using static stimuli, raising the question of 10 whether the observed robustness and “pop-out” quality of CI carries over to dynamic scenes. 11 We investigate contour detection in dynamic stimuli where targets appear at random times by 12 Gabor elements aligning themselves to form contours. In briefly presented displays (230ms), 13 a situation comparable to classical paradigms in CI, performance is about 87%. Surprisingly, 14 we find that detection performance decreases to 67% in extended presentations (about 1.9- 15 3.8s) for the same target stimuli. In order to observe the same reduction with briefly presented 16 stimuli, presentation time has to be drastically decreased to intervals as short as 50ms. Cueing a 17 specific contour position or shape helps in partially compensating this deterioration, and only in 18 extended presentations combining a location and a shape cue was more efficient than providing 19 a single cue. Our findings challenge the notion of CI as a mainly stimulus-driven process leading 20 to pop-out percepts, indicating that top-down processes play a much larger role in supporting 21 fundamental integration processes in dynamic scenes than previously thought. |

Several studies using behavioral or electrophysiological measures have demonstrated that this effect is modulated by the degree of formal overlap between translations. However, it has never been tested with a psychophysiological measure such as pupillometry. In the present study we replicate the cognate facilitation effect by examining reaction times and pupil responses. Our results endorse pupillometry as a promising tool for bilingual research, and confirm the modulation of the cognate effect by the degree of formal similarity. |
Ernesto Guerra; Pia Knoeferle In: Journal of Memory and Language, vol. 92, pp. 43–56, 2017. @article{Guerra2017, Recent experimental evidence suggests that spatial distance between two depicted objects in a non-referential visual context (i.e., when neither spatial distance nor the objects were mentioned) can rapidly and incrementally modulate the processing of semantic similarity between and-coordinated subject noun phrases in a sentence. The present research examines in three eye-tracking reading experiments whether these spatial distance effects extend to another abstract domain (social relations). More importantly, we assessed how precisely cognitive mechanisms link spatial information to sentence interpretation. To this end we varied between experiments the (order of the) constituents conveying information about social relations. We examined to what extent object distance effects on sentence interpretation depend upon a one-to-one mapping (relating objects to nouns). The eye-tracking record showed that spatial distance effects extended to abstract language other than semantic similarity and that these effects occurred as soon as the readers encountered linguistic information about social relations - independent of whether that information was conveyed by the (coordinated) nouns or by other constituents. Finally, the direction of the spatial distance effects seemed to depend on the activation level of the spatial distance representations, as determined by the constituent order. We discuss the contribution of these results to accounts of situated sentence comprehension. |
Juan Haro; Marc Guasch; Blanca Vallès; Pilar Ferré Is pupillary response a reliable index of word recognition? Evidence from a delayed lexical decision task Journal Article In: Behavior Research Methods, vol. 49, no. 5, pp. 1930–1938, 2017. @article{Haro2017, Previous word recognition studies have shown that the pupillary response is sensitive to a word's frequency. However, such a pupillary effect may be due to the process of executing a response, instead of being an index of word processing. With the aim of exploring this possibility, we recorded the pupillary responses in two experiments involving a lexical decision task (LDT). In the first experiment, participants completed a standard LDT, whereas in the second they performed a delayed LDT. The delay in the response allowed us to compare pupil dilations with and without the response execution component. The results showed that pupillary response was modulated by word frequency in both the standard and the delayed LDT. This finding supports the reliability of using pupillometry for word recognition research. Importantly, our results also suggest that tasks that do not require a response during pupil recording lead to clearer and stronger effects. |

Three factors known to modulate processing time in normal reading were investigated: Word length and word frequency were examined in Experiment 1, and target word predictability in Experiment 2. An analysis of global oculomotor behavior across the 2 experiments showed that participants made fewer and longer fixations when reading scrolling text, with shorter progressive and regressive saccades between these fixations. Comparisons of the linguistic manipulations showed evidence of a dissociation between word-level and sentence-level processing. Word-level processing (Experiment 1) was preserved for the dynamic scrolling text condition with no difference in length and frequency effects between scrolling and static text formats. However, sentence-level integration (Experiment 2) was reduced for scrolling compared to static text in that we obtained no early facilitation effect for predictable words under scrolling text conditions.

Perceptual features and object-scene semantic consistency have been found to attract our attention during scene exploration. The present study examined how visual attention in 24-month-old toddlers is attracted by semantic violations and how perceptual features (i. e. saliency, centre distance, clutter and object size) and linguistic properties (i. e. object label frequency and label length) affect gaze distribution. We compared eye movements of 24-month-old toddlers and adults while exploring everyday scenes which either contained an inconsistent (e.g., soap on a breakfast table) or consistent (e.g., soap in a bathroom) object. Perceptual features such as saliency, centre distance and clutter of the scene affected looking times in the toddler group during the whole viewing time whereas looking times in adults were affected only by centre distance during the early viewing time. Adults looked longer to inconsistent than consistent objects either if the objects had a high or a low saliency. In contrast, toddlers presented semantic consistency effect only when objects were highly salient. Additionally, toddlers with lower vocabulary skills looked longer to inconsistent objects while toddlers with higher vocabulary skills look equally long to both consistent and inconsistent objects. Our results indicate that 24-month-old children use scene context to guide visual attention when exploring the visual environment. However, perceptual features have a stronger influence in eye movement guidance in toddlers than in adults. Our results also indicate that language skills influence cognitive but not perceptual guidance of eye movements during scene perception in toddlers. |
Ehab W. Hermena; Simon P. Liversedge; Denis Drieghe In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 43, no. 3, pp. 451–471, 2017. @article{Hermena2017, The authors conducted 2 eye movement experiments in which they used the typographical and linguistic properties of Arabic to disentangle the influences of words' number of letters and spatial extent on measures of fixation duration and saccade targeting (Experiment 1), and to investigate the influence of initial bigram characteristics on saccade targeting during reading (Experiment 2). In the first experiment, through the use of a proportional font, which is more natural-looking in Arabic compared to monospaced fonts, the authors manipulated the number of letters (5 vs. 7) and the spatial extent (wide vs. narrow) of words embedded in frame sentences. The results obtained replicate and expand upon previous findings in other alphabetic languages that the number of letters influences fixation durations, whereas saccade targeting (as indicated by measures of fixation count and probability of skipping and refixation) is more influenced by the word's spatial extent. In the second experiment, the authors compared saccade targeting measures (saccade amplitude and initial fixation location) in 6- and 7-letter words beginning with initial bigrams that were of extremely high frequency ([character omitted] the), relatively high frequency ([character omitted] to/for the), or beginning with the letters of the word stem. The results showed negligible modulation of saccade targeting by initial bigram characteristics. The results also highlighted the importance of selecting the appropriate measures of initial fixation location (spatial vs. character-based measures) during reading text rendered using proportional fonts. |
Florian Hintz; Antje S. Meyer; Falk Huettig Predictors of verb-mediated anticipatory eye movements in the visual world Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 43, no. 9, pp. 1352–1374, 2017. @article{Hintz2017, Many studies have demonstrated that listeners use information extracted from verbs to guide anticipatory eye movements to objects in the visual context that satisfy the selection restrictions of the verb. An important question is what underlies such verb-mediated anticipatory eye gaze. Based on empirical and theoretical suggestions, we investigated the influence of 5 potential predictors of this behavior: functional associations and general associations between verb and target object, as well as the listeners' production fluency, receptive vocabulary knowledge, and nonverbal intelligence. In 3 eye-tracking experiments, participants looked at sets of 4 objects and listened to sentences where the final word was predictable or not predictable (e.g., "The man peels/draws an apple"). On predictable trials only the target object, but not the distractors, were functionally and associatively related to the verb. In Experiments 1 and 2, objects were presented before the verb was heard. In Experiment 3, participants were given a short preview of the display after the verb was heard. Functional associations and receptive vocabulary were found to be important predictors of verb-mediated anticipatory eye gaze independent of the amount of contextual visual input. General word associations did not and nonverbal intelligence was only a very weak predictor of anticipatory eye movements. Participants' production fluency correlated positively with the likelihood of anticipatory eye movements when participants were given the long but not the short visual display preview. These findings fit best with a pluralistic approach to predictive language processing in which multiple mechanisms, mediating factors, and situational context dynamically interact. |
Paul Metzner; Titus Malsburg; Shravan Vasishth; Frank Rösler The importance of reading naturally: Evidence from combined recordings of eye movements and electric brain potentials Journal Article In: Cognitive Science, vol. 41, pp. 1232–1263, 2017. @article{Metzner2017, How important is the ability to freely control eye movements for reading comprehension? And how does the parser make use of this freedom? We investigated these questions using coregistration of eye movements and event-related brain potentials (ERPs) while participants read either freely or in a computer-controlled word-by-word format (also known as RSVP). Word-by-word presentation and natural reading both elicited qualitatively similar ERP effects in response to syntactic and semantic violations (N400 and P600 effects). Comprehension was better in free reading but only in trials in which the eyes regressed to previous material upon encountering the anomaly. A more fine-grained ERP analysis revealed that these regressions were strongly associated with the well-known P600 effect. In trials without regressions, we instead found sustained centro-parietal negativities starting at around 320 ms post-onset; however, these negativities were only found when the violation occurred in sentence-final position. Taken together, these results suggest that the sentence processing system engages in strategic choices: In response to words that don't match built-up expectations, it can either explore alternative interpretations (reflected by regressions, P600 effects, and good com-prehension) or pursue a " good-enough " processing strategy that tolerates a deficient interpretation (reflected by progressive saccades, sustained negativities, and relatively poor comprehension). |

Joseph; Mila Vulchanova; David Saldaña Strategies of readers with autism when responding to inferential questions: An eye-movement study Journal Article In: Autism Research, vol. 10, no. 5, pp. 888–900, 2017. @article{Micai2017, Previous research suggests that individuals with autism spectrum disorder (ASD) have difficulties with inference generation in reading tasks. However, most previous studies have examined how well children understand a text after reading or have measured on-line reading behavior without response to questions. The aim of this study was to investigate the online strategies of children and adolescents with autism during reading and at the same time responding to a question by monitoring their eye movements. The reading behavior of participants with ASD was compared with that of age-, language-, nonverbal intelligence-, reading-, and receptive language skills-matched participants without ASD (control group). The results showed that the ASD group were as accurate as the control group in generating inferences when answering questions about the short texts, and no differences were found between the two groups in the global paragraph reading and responding times. However, the ASD group displayed longer gaze latencies on a target word necessary to produce an inference. They also showed more regressions into the word that supported the inference compared to the control group after reading the question, irrespective of whether an inference was required or not. In conclusion, the ASD group achieved an equivalent level of inferential comprehension, but showed subtle differences in reading comprehension strategies compared to the control group. |
Sanako Mitsugi Incremental comprehension of Japanese passives: Evidence from the visual-world paradigm Journal Article In: Applied Psycholinguistics, vol. 38, no. 4, pp. 953–983, 2017. @article{Mitsugi2017, Psycholinguistic research has shown that sentence processing is incremental (e.g., Altmann & Kamide, 1999). In Japanese, a verb-final language, native speakers use case markers to incrementally assign thematic roles and predictively activate a structural representation of upcoming linguistic items. This study examined whether second-language learners of Japanese, guided by case markers, generate predictions as to whether the upcoming verb involves the active or passive voice. The results show that the native speakers made predictive eye movements before the verb, but the learners did not; the learners were less efficient in using case-marker cues than the native speakers and relied more on verb morphology information. These results suggest that case markers guide thematic role assignments, expediting the processing for Japanese native speakers. Learners may depend more on information from the verb to compensate for the inefficiency in case-marker-driven predictive processing. |
Holger Mitterer; Eva Reinisch Visual speech influences speech perception immediately but not automatically Journal Article In: Attention, Perception, and Psychophysics, vol. 79, no. 2, pp. 660–678, 2017. @article{Mitterer2017, Two experiments examined the time course of the use of auditory and visual speech cues to spoken word recognition using an eye-tracking paradigm. Results of the first experiment showed that the use of visual speech cues from lipreading is reduced if concurrently presented pictures require a division of attentional resources. This reduction was evident even when listeners' eye gaze was on the speaker rather than the (static) pictures. Experiment 2 used a deictic hand gesture to foster attention to the speaker. At the same time, the visual processing load was reduced by keeping the visual display constant over a fixed number of successive trials. Under these conditions, the visual speech cues from lipreading were used. Moreover, the eye-tracking data indicated that visual information was used immediately and even earlier than auditory information. In combination, these data indicate that visual speech cues are not used automatically, but if they are used, they are used immediately. |
Koji Miwa; Ton Dijkstra Lexical processes in the recognition of Japanese horizontal and vertical compounds Journal Article In: Reading and Writing, vol. 30, no. 4, pp. 791–812, 2017. @article{Miwa2017a, This lexical decision eye-tracking study investigated whether horizontal and vertical readings elicit comparable behavioral patterns and whether reading directions modulate lexical processes. Response times and eye movements were recorded during a lexical decision task with Japanese bimorphemic compound words presented vertically. The data were then analyzed together with those obtained in a horizontal lexical decision experiment of Miwa, Libben, Dijkstra, and Baayen (2014). Linear mixed-effects analyses of response times and eye movements revealed that, although response times and first fixation durations were notably shorter in horizontal reading than vertical reading, the vertical reading elicited fewer fixations. Furthermore, while compounds were recognized largely in comparable ways regardless of reading direction, several lexical processes were found to be reading-direction-dependent. Particularly, processing of the first morpheme was modulated by reading direction in a late time frame, such that a horizontal reading advantage was observed for words with a high frequency first morpheme. All in all, the two reading directions do not only differ quantitatively in processing speed, but also qualitatively in terms of underlying processing mechanisms. |
Koji Miwa; Gary Libben; Yu Ikemoto Visual trimorphemic compound recognition in a morphographic script Journal Article In: Language, Cognition and Neuroscience, vol. 32, no. 1, pp. 1–20, 2017. @article{Miwa2017, This lexical decision with eye-tracking study investigated how Japanese trimorphemic compounds (e.g. 体温計 “clinical thermometer”) are recognised. The questions answered were, in the course of decomposing and composing Japanese trimorphemic compounds, (1) whether recognition processes are tuned for a specific branching direction, (2) whether the morphological processing proceeds in a bottom-up combinatorial manner, and (3) whether the three constituents of trimorphemic compounds are equally important and processed serially. Mixed-effects regression analyses of response times and fixation durations revealed that a left-branching advantage appears in a late time frame and that, although there was early processing of the whole compound from the first fixation, a character frequency effect was also observed. Furthermore, the first and the third, but not the second, constituent frequencies contributed to compound recognition. This bathtub-like effect was further supported by corpus-based evidence: the conditional probability for the second constituent is incomparably high. |

In a simple reasoning scenario, we monitored children's eye-movements while processing a sentence with modal expressions of different force (might/must). Children were also asked to judge the truth-value of the target sentences at the end of the reasoning task. Consistent with previous findings (Noveck, 2001), we found that children's behavioural responses were much less accurate compared to adults. Their eye-movements, however, revealed that children did not treat the two modal expressions alike. As soon as a modal expression was presented, children and adults showed a similar fixation pattern that varied as a function of the modal expression they heard. It is only at the very end of the sentence that children's fixations diverged from the adult ones. We discuss these findings in relation to the proposal that children narrow down the set of possible outcomes in undetermined reasoning scenarios and endorse only one possibility among several (Acredolo & Horobin, 1987, Ozturk & Papafragou, 2015). |
Hermann J. Mueller; Thomas Geyer; Franziska Günther; Jim Kacian; Stella Pierides Reading English-Language haiku: Processes of meaning construction revealed by eye movements Journal Article In: Journal of Eye Movement Research, vol. 10, no. 1, pp. 1–33, 2017. @article{Mueller2017, In the present study, poets and cognitive scientists came together to investigate the construction of meaning in the process of reading normative, 3-line English-language haiku (ELH), as found in leading ELH journals. The particular haiku which we presented to our readers consisted of two semantically separable parts, or images, that were set in a ‘tense' relationship by the poet. In our sample of poems, the division, or cut, between the two parts was positioned either after line 1 or after line 2; and the images related to each other in terms of either a context–action association (context–action haiku) or a conceptually more abstract association (juxtaposition haiku). From a constructivist perspective, understanding such haiku would require the reader to integrate these parts into a coherent ‘meaning Gestalt', mentally (re-)creating the pattern intended by the poet (or one from within the poem's meaning potential). To examine this process, we recorded readers' eye movements, and we obtained measures of memory for the read poems as well as subjective ratings of comprehension difficulty and understanding achieved. The results indicate that processes of meaning construction are reflected in patterns of eye movements during reading (1st-pass) and re-reading (2nd- and 3rd-pass). From those, the position of the cut (after line 1 vs. after line 2) and, to some extent, the type of haiku (context–action vs. juxtaposition) can be ‘recovered'. Moreover, post-reading, readers tended to explicitly recognize a particular haiku they had read if they had been able to understand the poem, pointing to a role of actually resolving the haiku's meaning (rather than just attempting to resolve it) for memory consolidation and subsequent retrieval. Taken together, these first findings are promising, suggesting that haiku can be a paradigmatic material for studying meaning construction during poetry reading. |
Daniel J. Olson Bilingual language switching costs in auditory comprehension Journal Article In: Language, Cognition and Neuroscience, vol. 32, no. 4, pp. 494–513, 2017. @article{Olson2017, Previous research on bilingual language switching and lexical access has demonstrated a consistent reaction time cost associated with producing a switched token. While some studies have shown these costs to be asymmetrical, with bilinguals evidencing a greater delay when producing switches into their dominant language relative to the non-dominant language, others have shown symmetrical costs, depending on individual (e.g. proficiency) and contextual (e.g. language mode) factors. The current study, employing an eye-tracking paradigm, extends this line of research by examining the potential for switch costs during auditory comprehension. Paralleling previous production-oriented research, results of the current study demonstrate flexible switch costs during auditory comprehension. Switch costs were asymmetrical in monolingual mode, with greater costs incurred when switching into the dominant language, and uniformly absent in bilingual mode. Results are discussed with respect to bilingual language selection mechanisms in both production and comprehension. |

Jean-Baptiste Bernard; Carlos Aguilar; Eric Castet In: PLoS ONE, vol. 11, no. 4, pp. e0152506, 2016. @article{Bernard2016b, Reading speed is dramatically reduced when readers cannot use their central vision. This is because low visual acuity and crowding negatively impact letter recognition in the periphery. In this study, we designed a new font (referred to as the Eido font) in order to reduce inter-letter similarity and consequently to increase peripheral letter recognition performance. We tested this font by running five experiments that compared the Eido font with the standard Courier font. Letter spacing and x-height were identical for the two monospaced fonts. Six normally-sighted subjects used exclusively their peripheral vision to run two aloud reading tasks (with eye movements), a letter recognition task (without eye movements), a word recognition task (without eye movements) and a lexical decision task. Results show that reading speed was not significantly different between the Eido and the Courier font when subjects had to read single sentences with a round simulated gaze-contingent central scotoma (10° diameter). In contrast, Eido significantly decreased perceptual errors in peripheral crowded letter recognition (-30% errors on average for letters briefly presented at 6° eccentricity) and in peripheral word recognition (-32% errors on average for words briefly presented at 6° eccentricity). |
Megan H. Papesh; Stephen D. Goldinger; Michael C. Hout Eye movements reveal fast, voice-specific priming Journal Article In: Journal of Experimental Psychology: General, vol. 145, no. 3, pp. 314–337, 2016. @article{Papesh2016, In spoken word perception, voice specificity effects are well-documented: When people hear repeated words in some task, performance is generally better when repeated items are presented in their originally heard voices, relative to changed voices. A key theoretical question about voice specificity effects concerns their time-course: Some studies suggest that episodic traces exert their influence late in lexical processing (the time-course hypothesis; McLennan & Luce, 2005), whereas others suggest that episodic traces influence immediate, online processing. We report 2 eye-tracking studies investigating the time-course of voice-specific priming within and across cognitive tasks. In Experiment 1, participants performed modified lexical decision or semantic classification to words spoken by 4 speakers. The tasks required participants to click a red "x" or a blue "+" located randomly within separate visual half-fields, necessitating trial-by-trial visual search with consistent half-field response mapping. After a break, participants completed a second block with new and repeated items, half spoken in changed voices. Voice effects were robust very early, appearing in saccade initiation times. Experiment 2 replicated this pattern while changing tasks across blocks, ruling out a response priming account. In the General Discussion, we address the time-course hypothesis, focusing on the challenge it presents for empirical disconfirmation, and highlighting the broad importance of indexical effects, beyond studies of priming. |
Bob McMurray; Ashley Farris-Trimble; Michael Seedorff; Hannah Rigler The effect of residual acoustic hearing and adaptation to uncertainty on speech perception in cochlear implant users: Evidence from eye-tracking Journal Article In: Ear & Hearing, vol. 37, no. 1, pp. e37–e51, 2016. @article{McMurray2016, OBJECTIVES: While outcomes with cochlear implants (CIs) are generally good, performance can be fragile. The authors examined two factors that are crucial for good CI performance. First, while there is a clear benefit for adding residual acoustic hearing to CI stimulation (typically in low frequencies), it is unclear whether this contributes directly to phonetic categorization. Thus, the authors examined perception of voicing (which uses low-frequency acoustic cues) and fricative place of articulation (s/ʃ, which does not) in CI users with and without residual acoustic hearing. Second, in speech categorization experiments, CI users typically show shallower identification functions. These are typically interpreted as deriving from noisy encoding of the signal. However, psycholinguistic work suggests shallow slopes may also be a useful way to adapt to uncertainty. The authors thus employed an eye-tracking paradigm to examine this in CI users. DESIGN: Participants were 30 CI users (with a variety of configurations) and 22 age-matched normal hearing (NH) controls. Participants heard tokens from six b/p and six s/ʃ continua (eight steps) spanning real words (e.g., beach/peach, sip/ship). Participants selected the picture corresponding to the word they heard from a screen containing four items (a b-, p-, s- and ʃ-initial item). Eye movements to each object were monitored as a measure of how strongly they were considering each interpretation in the moments leading up to their final percept. RESULTS: Mouse-click results (analogous to phoneme identification) for voicing showed a shallower slope for CI users than NH listeners, but no differences between CI users with and without residual acoustic hearing. For fricatives, CI users also showed a shallower slope, but unexpectedly, acoustic + electric listeners showed an even shallower slope. Eye movements showed a gradient response to fine-grained acoustic differences for all listeners. Even considering only trials in which a participant clicked "b" (for example), and accounting for variation in the category boundary, participants made more looks to the competitor ("p") as the voice onset time neared the boundary. CI users showed a similar pattern, but looked to the competitor more than NH listeners, and this was not different at different continuum steps. CONCLUSION: Residual acoustic hearing did not improve voicing categorization suggesting it may not help identify these phonetic cues. The fact that acoustic + electric users showed poorer performance on fricatives was unexpected as they usually show a benefit in standardized perception measures, and as sibilants contain little energy in the low-frequency (acoustic) range. The authors hypothesize that these listeners may overweight acoustic input, and have problems when this is not available (in fricatives). Thus, the benefit (or cost) of acoustic hearing for phonetic categorization may be complex. Eye movements suggest that in both CI and NH listeners, phoneme categorization is not a process of mapping continuous cues to discrete categories. Rather listeners preserve gradiency as a way to deal with uncertainty. CI listeners appear to adapt to their implant (in part) by amplifying competitor activation to preserve their flexibility in the face of potential misperceptions. |

Liversedge Parafoveal preprocessing of word initial trigrams during reading in adults and children Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 3, pp. 411–432, 2016. @article{Pagan2016a, Although previous research has shown that letter position information for the first letter of a parafoveal word is encoded less flexibly than internal word beginning letters (Johnson, Perea & Rayner, 2007; White et al., 2008), it is not clear how positional encoding operates over the initial trigram in English. This experiment explored the preprocessing of letter identity and position information of a parafoveal word's initial trigram by adults and children using the boundary paradigm during normal sentence reading. Seven previews were generated: Identity (captain); transposed letter and substituted letter nonwords in Positions 1 and 2 (acptain-imptain); 1 and 3 (pactain-gartain), and 2 and 3 (cpatain-cgotain). Results showed a transposed letter effect (TLE) in Position 13 for gaze duration in the pretarget word; and TLE in Positions 12 and 23 but not in Position 13 in the target word for both adults and children. These findings suggest that children, similar to adults, extract letter identity and position information flexibly using a spatial coding mechanism; supporting isolated word recognition models such as SOLAR (Davis, 1999, 2010) and SERIOL (Whitney, 2001) models. |

Liversedge An inhibitory influence of transposed-letter neighbors on eye movements during reading Journal Article In: Psychonomic Bulletin & Review, vol. 23, no. 1, pp. 278–284, 2016. @article{Pagan2016, Previous research has shown that prior exposure to a word's substitution neighbor earlier in the same sentence can disrupt processing of that word, indicating that interword lexical priming occurs naturally during reading, due to the competition between lexical candidates during word identification. Through the present research, we extended these findings by investigating the effects of prior exposure to a word's transposed-letter neighbor (TLN) earlier in a sentence. TLNs are constituted from the same letters, but in different orders. The findings revealed an inhibitory TLN effect, with longer total reading times for target words, and increased regressions to prime and target words, when the target followed a TLN rather than a control word. These findings indicate that prior exposure to a TLN can disrupt word identification during reading. We suggest that this is caused by a failure of word identification, due to the initial misidentification of the target word (potentially as its TLN) triggering postlexical checking. |
Jinger Pan; Jochen Laubrock; Ming Yan In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 8, pp. 1257–1273, 2016. @article{Pan2016, We examined how reading mode (i.e., silent vs. oral reading) influences parafoveal semantic and phonological processing during the reading of Chinese sentences, using the gaze-contingent boundary paradigm. In silent reading, we found in 2 experiments that reading times on target words were shortened with semantic previews in early and late processing, whereas phonological preview effects mainly occurred in gaze duration or second-pass reading. In contrast, results showed that phonological preview information is obtained early on in oral reading. Strikingly, in oral reading, we observed a semantic preview cost on the target word in Experiment 1 and a decrease in the effect size of preview benefit from first- to second-pass measures in Experiment 2, which we hypothesize to result from increased preview duration. Taken together, our results indicate that parafoveal semantic information can be obtained irrespective of reading mode, whereas readers more efficiently process parafoveal phonological information in oral reading. We discuss implications for notions of information processing priority and saccade generation during silent and oral reading. |

Here, using MEG we directly investigated how these visual signals interact with rhythmic brain activity in participants listening to and seeing the speaker. First, we investigated coherence between oscillatory brain activity and speaker's lip movements and demonstrated significant entrainment in visual cortex. We then used partial coherence to remove contributions of the coherent auditory speech signal from the lip-brain coherence. Comparing this synchronization between different attention conditions revealed that attending visual speech enhances the coherence between activity in visual cortex and the speaker's lips. Further, we identified a significant partial coherence between left motor cortex and lip movements and this partial coherence directly predicted comprehension accuracy. Our results emphasize the importance of visually entrained and attention-modulated rhythmic brain activity for the enhancement of audiovisual speech processing. |
Umesh Patil; Shravan Vasishth; Richard L. Lewis Retrieval interference in syntactic processing: The case of reflexive binding in English Journal Article In: Frontiers in Psychology, vol. 7, pp. 329, 2016. @article{Patil2016, It has been proposed that in online sentence comprehension the dependency between a reflexive pronoun such as himself/herself and its antecedent is resolved using exclusively syntactic constraints. Under this strictly syntactic search account, Principle A of the binding theory-which requires that the antecedent c-command the reflexive within the same clause that the reflexive occurs in-constrains the parser's search for an antecedent. The parser thus ignores candidate antecedents that might match agreement features of the reflexive (e.g., gender) but are ineligible as potential antecedents because they are in structurally illicit positions. An alternative possibility accords no special status to structural constraints: in addition to using Principle A, the parser also uses non-structural cues such as gender to access the antecedent. According to cue-based retrieval theories of memory (e.g., Lewis and Vasishth, 2005), the use of non-structural cues should result in increased retrieval times and occasional errors when candidates partially match the cues, even if the candidates are in structurally illicit positions. In this paper, we first show how the retrieval processes that underlie the reflexive binding are naturally realized in the Lewis and Vasishth (2005) model. We present the predictions of the model under the assumption that both structural and non-structural cues are used during retrieval, and provide a critical analysis of previous empirical studies that failed to find evidence for the use of non-structural cues, suggesting that these failures may be Type II errors. We use this analysis and the results of further modeling to motivate a new empirical design that we use in an eye tracking study. The results of this study confirm the key predictions of the model concerning the use of non-structural cues, and are inconsistent with the strictly syntactic search account. These results present a challenge for theories advocating the infallibility of the human parser in the case of reflexive resolution, and provide support for the inclusion of agreement features such as gender in the set of retrieval cues. |

Federmeier Out of the corner of my eye: Foveal semantic load modulates parafoveal processing in reading Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 42, no. 11, pp. 1839–1857, 2016. @article{Payne2016, In 2 experiments, we examined the impact of foveal semantic expectancy and congruity on parafoveal word processing during reading. Experiment 1 utilized an eye-tracking gaze-contingent display change paradigm, and Experiment 2 measured event-related brain potentials (ERPs) in a modified flanker rapid serial visual presentation (RSVP) paradigm. Eye-tracking and ERP data converged to reveal graded effects of foveal load on parafoveal processing. In Experiment 1, when word n was highly expected, and thus foveal load was low, there was a large parafoveal preview benefit to word n = 1. When word n was unexpected but still plausible, preview benefits to n = 1 were reduced in magnitude, and when word n was semantically incongruent, the preview benefit to n = 1 was unreliable in early pass measures. In Experiment 2, ERPs indicated that when word n was expected, and thus foveal load was low, readers successfully discriminated between valid and orthographically invalid previews during parafoveal perception. However, when word n was unexpected, parafoveal processing of n = 1 was reduced, and it was eliminated when word n was semantically incongruent. Taken together, these findings suggest that sentential context modulates the allocation of attention in the parafovea, such that covert allocation of attention to parafoveal processing is disrupted when foveal words are inconsistent with expectations based on various contextual constraints. |
Ana Pellicer-Sánchez Incidental L2 vocabulary acquisition from and while reading: An eye-tracking study Journal Article In: Studies in Second Language Acquisition, vol. 38, no. 1, pp. 97–130, 2016. @article{PellicerSanchez2016, Previous studies have shown that reading is an important source of incidental second language (L2) vocabulary acquisition. However, we still do not have a clear picture of what happens when readers encounter unknown words. Combining offline (vocabulary tests) and online (eye-tracking) measures, the incidental acquisition of vocabulary knowledge from reading and the online reading of unknown lexical items were examined. L2 English learners read a story containing unknown items while their eye movements were recorded. After eight exposures, L2 readers recognized the form and the meaning of 86% and 75% of the target nonwords, respectively, whereas they recalled the meaning of 55% of the nonwords. After three to four encounters, nonwords were read significantly faster, and by eight encounters they were read in a similar manner to previously known real words. Results also showed a positive relationship between new vocabulary learning outcomes and online reading, with longer reading times associated with higher vocabulary recall test scores. The study was also conducted with first language (L1) readers to provide baseline data for comparison. Results confirmed the L2 findings while also indicating an interesting L1-L2 distinction in the rate rather than in the ultimate outcome of the acquisition process. |

Journal Article In: Spanish Journal of Psychology, vol. 19, pp. 1–7, 2016. @article{Perea2016, A number of experiments have shown that, in skilled adult readers, a small increase in interletter spacing speeds up the process of visual word recognition relative to the default settings (i.e., judge faster than judge). The goal of the present experiment was to examine whether this effect can be generalized to a more ecological scenario: text reading. Each participant read two stories (367 words each) taken from a standardized reading test. The stories were presented with the standard interletter spacing or with a small increase in interletter spacing (+1.2 points to default) in a within-subject design. An eyetracker was used to register the participants' eye movements. Comprehension scores were also examined. Results showed that, on average, fixation durations were shorter while reading the text with extra spacing than while reading the text with the default settings (237 vs. 245 ms, respectively; η2 =. 41 |
Ewa Pluciennicka; Yann Coello; Solène Kalénine In: Cognitive Development, vol. 38, pp. 75–88, 2016. @article{Pluciennicka2016, This study assessed the implicit processing development of three types of semantic relations during manipulable artifact identification. Thirteen adults and thirty-nine children (age 6, 8, and 10 years) participated. Fixation temporal dynamics were used to assess competition effects from thematic (e.g., wood), specific function (e.g., axe), and general function (e.g., knife) distractors during target identification (e.g., saw). Competition effects were analyzed depending on distractor type and age group. Developmental results demonstrate emergence of competition effects with general function distractors with age, whereas competition effects with thematic and specific function distractors were stable from 6. Findings highlight fined-grained development of similarity-based semantic mechanism implicit use during object processing from 6 to adulthood. They further suggest that complementarity-based mechanism is efficiently used during object semantic processing starting from 6 and likely involved in processing both thematic and specific function relations. |

Recent behavioral and neurophysiological evidence indicates that while they are all relevant for manipulable artifact concepts, semantic relations based on thematic (e.g., saw-wood), specific function similarity (e.g., saw-axe), and general function similarity (e.g., saw-knife) are differently processed, and may relate to different levels of action representation. Point-light displays of object-related actions previously encoded at the gesture level (e.g., "sawing") or at the higher level of action representation (e.g., "cutting") were used as primes before participants identified target objects (e.g., saw) among semantically related and unrelated distractors (e.g., wood, feather, piano). Analysis of eye movements on the different objects during target identification informed about the amplitude and the timing of implicit activation of the different semantic relations. Results showed that action prime encoding impacted the processing of thematic relations, but not that of functional similarity relations. Semantic competition with thematic distractors was greater and earlier following action primes encoded at the gesture level compared to action primes encoded at higher level. As a whole, these findings highlight the direct influence of action representations on thematic relation processing, and suggest that thematic relations involve gesture-level representations rather than intention-level representations. |
Yanping Liu; Erik D. Reichle; Xingshan Li The effect of word frequency and parafoveal preview on saccade length during the reading of Chinese Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 42, no. 7, pp. 1008–1025, 2016. @article{Liu2016, There are currently 2 theoretical accounts of how readers of Chinese select their saccade targets: (a) by moving their eyes to specific saccade targets (i.e., the default-targeting hypothesis) and (b) by adjusting their saccade lengths to accommodate lexical processing (i.e., the dynamic-adjustment hypothesis). In this article, we first report the results of an eye-movement experiment using a gaze-contingent boundary paradigm. This experiment demonstrates that both target-word frequency and its preview validity modulate the lengths of the saccades entering and exiting the target words, with longer saccades to/from high-frequency words when their preview was available. We then report the results of 2 simulations using computational models that instantiate the core theoretical assumptions of the default-targeting and dynamic-adjustment hypotheses. Comparisons of these simulations indicate that the dynamic-adjustment hypothesis provides a better quantitative account of the data from our experiment using fewer free parameters. We conclude by discussing evidence for dynamic saccade adjustment during the reading of alphabetic languages, and why such a heuristic may be necessary to fully explain eye-movement control during the reading of both alphabetic and nonalphabetic languages. |

Liversedge; Denis Drieghe; Xin Li; Guoli Yan; Xuejun Bai; Jukka Hyönä Universality in eye movements and reading: A trilingual investigation Journal Article In: Cognition, vol. 147, pp. 1–20, 2016. @article{Liversedge2016, Universality in language has been a core issue in the fields of linguistics and psycholinguistics for many years (e.g., Chomsky, 1965). Recently, Frost (2012) has argued that establishing universals of process is critical to the development of meaningful, theoretically motivated, cross-linguistic models of reading. In contrast, other researchers argue that there is no such thing as universals of reading (e.g., Coltheart & Crain, 2012). Reading is a complex, visually mediated psychological process, and eye movements are the behavioural means by which we encode the visual information required for linguistic processing. To investigate universality of representation and process across languages we examined eye movement behaviour during reading of very comparable stimuli in three languages, Chinese, English and Finnish. These languages differ in numerous respects (character based vs. alphabetic, visual density, informational density, word spacing, orthographic depth, agglutination, etc.). We used linear mixed modelling techniques to identify variables that captured common variance across languages. Despite fundamental visual and linguistic differences in the orthographies, statistical models of reading behaviour were strikingly similar in a number of respects, and thus, we argue that their composition might reflect universality of representation and process in reading. |

Visual input enhancement has been used to investigate the effects of highlighting specific grammatical structures in a text. The current study uses a quasi-experimental design to determine the extent to which textual manipulation increase (a) learners' perception of targeted forms and (b) their knowledge of the forms. Input enhancement was used to highlight the Spanish preterit and imperfect verb forms and an eye tracker measured the frequency and duration of participants' fixation on the targeted items. In addition, pretests and posttests of the Spanish past tense provided information about participants' knowledge of the targeted forms. Results indicate that learners were aware of the highlighted grammatical forms in the text; however, there was no difference in the amount of attention between the enhanced and unenhanced groups. In addition, both groups improved in their knowledge of the L2 forms; however, again, there was no differential improvement between the two groups. |
Matthew W. Lowder; Fernanda Ferreira Prediction in the processing of repair disfluencies: Evidence from the Visual-World Paradigm Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 9, pp. 1400–1416, 2016. @article{Lowder2016, Two visual-world eye-tracking experiments investigated the role of prediction in the processing of repair disfluencies (e.g., "The chef reached for some salt uh I mean some ketchup . . ."). Experiment 1 showed that listeners were more likely to fixate a critical distractor item (e.g., pepper) during the processing of repair disfluencies compared with the processing of coordination structures (e.g., ". . . some salt and also some ketchup . . ."). Experiment 2 replicated the findings of Experiment 1 for disfluency versus coordination constructions and also showed that the pattern of fixations to the critical distractor for disfluency constructions was similar to the fixation patterns for sentences employing contrastive focus (e.g., ". . . not some salt but rather some ketchup . . ."). The results suggest that similar mechanisms underlie the processing of repair disfluencies and contrastive focus, with listeners generating sets of entities that stand in semantic contrast to the reparandum in the case of disfluencies or the negated entity in the case of contrastive focus. |

Gordon Eye-tracking and corpus-based analyses of syntax-semantics interactions in complement coercion Journal Article In: Language, Cognition and Neuroscience, vol. 31, no. 7, pp. 921–939, 2016. @article{Lowder2016a, Previous work has shown that the difficulty associated with processing complex semantic expressions is reduced when the critical constituents appear in separate clauses as opposed to when they appear together in the same clause. We investigated this effect further, focusing in particular on complement coercion, in which an event-selecting verb (e.g. began) combines with a complement that represents an entity (e.g. began the memo). Experiment 1 compared reading times for coercion versus control expressions when the critical verb and complement appeared together in a subject-extracted relative clause (SRC) (e.g. The secretary that began/wrote the memo) compared to when they appeared together in a simple sentence. Readers spent more time processing coercion expressions than control expressions, replicating the typical coercion cost. In addition, readers spent less time processing the verb and complement in SRCs than in simple sentences; however, the magnitude of the coercion cost did not depend on sentence structure. In contrast, Experiment 2 showed that the coercion cost was reduced when the complement appeared as the head of an object-extracted relative clause (ORC) (e.g. The memo that the secretary began/wrote) compared to when the constituents appeared together in an SRC. Consistent with the eye-tracking results of Experiment 2, a corpus analysis showed that expressions requiring complement coercion are more frequent when the constituents are separated by the clause boundary of an ORC compared to when they are embedded together within an SRC. The results provide important information about the types of structural configurations that contribute to reduced difficulty with complex semantic expressions, as well as how these processing patterns are reflected in naturally occurring language. |
Steven G. Luke; Kiel Christianson Limits on lexical prediction during reading Journal Article In: Cognitive Psychology, vol. 88, pp. 22–60, 2016. @article{Luke2016, Efficient language processing may involve generating expectations about upcoming input. To investigate the extent to which prediction might facilitate reading, a large-scale survey provided cloze scores for all 2689 words in 55 different text passages. Highly predictable words were quite rare (5% of content words), and most words had a more-expected competitor. An eye-tracking study showed sensitivity to cloze probability but no mis-prediction cost. Instead, the presence of a more-expected competitor was found to be facilitative in several measures. Further, semantic and morphosyntactic information was highly predictable even when word identity was not, and this information facilitated reading above and beyond the predictability of the full word form. The results are consistent with graded prediction but inconsistent with full lexical prediction. Implications for theories of prediction in language comprehension are discussed. |
Steven G. Luke; John M. Henderson The influence of content meaningfulness on eye movements across tasks: Evidence from scene viewing and reading Journal Article In: Frontiers in Psychology, vol. 7, pp. 257, 2016. @article{Luke2016a, The present study investigated the influence of content meaningfulness on eye-movement control in reading and scene viewing. Texts and scenes were manipulated to make them uninterpretable, and then eye-movements in reading and scene-viewing were compared to those in pseudo-reading and pseudo-scene viewing. Fixation durations and saccade amplitudes were greater for pseudo-stimuli. The effect of the removal of meaning was seen exclusively in the tail of the fixation duration distribution in both tasks, and the size of this effect was the same across tasks. These findings suggest that eye movements are controlled by a common mechanism in reading and scene viewing. They also indicate that not all eye movements are responsive to the meaningfulness of stimulus content. Implications for models of eye movement control are discussed. |

We examined the relationship between linguistic competition resolution and nonlinguistic cognitive control in younger and older adults who were either bilingual or monolingual. Participants heard words in English and identified the referent among four pictures while eye-movements were recorded. Target pictures (e.g., cab ) appeared with a phonological competitor picture (e.g., cat ) and two filler pictures. After each eye-tracking trial, priming probes assessed residual activation and inhibition of target and competitor words. When accounting for processing speed, results revealed that age-related changes in activation and inhibition are smaller in bilinguals than in monolinguals. Moreover, younger and older bilinguals, but not monolinguals, recruited similar inhibition mechanisms during word identification and during a nonlinguistic Stroop task. Results suggest that, during lexical access, bilinguals show more consistent competition resolution and recruitment of cognitive control across the lifespan than monolinguals. |
Christina Marx; Florian Hutzler; Sarah Schuster; Stefan Hawelka On the development of parafoveal preprocessing: Evidence from the incremental boundary paradigm Journal Article In: Frontiers in Psychology, vol. 7, pp. 514, 2016. @article{Marx2016, Parafoveal preprocessing of upcoming words and the resultant preview benefit are key aspects of fluent reading. Evidence regarding the development of parafoveal preprocessing during reading acquisition, however, is scarce. The present developmental (cross-sectional) eye tracking study estimated the magnitude of parafoveal preprocessing of beginning readers with a novel variant of the classical boundary paradigm. Additionally, we assessed the association of parafoveal preprocessing with several reading-related psychometric measures. The participants were children learning to read the regular German orthography with about 1, 3, and 5 years of formal reading instruction (Grade 2, 4, and 6, respectively). We found evidence of parafoveal preprocessing in each Grade. However, an effective use of parafoveal information was related to the individual reading fluency of the participants (i.e., the reading rate expressed as words-per-minute) which substantially overlapped between the Grades. The size of the preview benefit was furthermore associated with the children's performance in rapid naming tasks and with their performance in a pseudoword reading task. The latter task assessed the children's efficiency in phonological decoding and our findings show that the best decoders exhibited the largest preview benefit. |
Katrine Sand; Thomas Habekost; Anders Petersen; Randi Starrfelt The Word Superiority Effect in central and peripheral vision Journal Article In: Visual Cognition, vol. 24, no. 4, pp. 293–303, 2016. @article{Sand2016, The Word Superiority Effect (WSE) is a well-known phenomenon in reading research, where words are reported more accurately than single letters or non-words. We report two experiments that investigate the WSE in the central and peripheral visual field, as well as laterality differences in the perception of words and letters, using methods based on the Theory of Visual Attention. The results show a WSE in the central visual field, reflected in mean scores, perception thresholds, and processing speed, whereas the effect is eliminated or reversed in the periphery. This may be caused by crowding, which prevents lexical analysis of a word in the periphery. We conclude that perception of words and letters differs according to location in the visual field. Linking our results to previous studies of crowding effects in patients with reading impairments, we hypothesize that similar mechanisms may limit normal word peripheral processing. |

Although interrogation warnings differ in their text characteristics, empirically examining the influence of these text differences on suspects' ability to process and comprehend their rights has largely been neglected, which is especially problematic for vulnerable populations. Using a novel approach, we monitored the eye movements of 60 juveniles as they silently read different versions of Miranda warnings in order to investigate the relationship among text characteristics, processing difficulty, and comprehension problems. Results indicated that text characteristics were associated with processing difficulties and these processing difficulties were strongly correlated with comprehension of the warnings. Along with advancing basic and applied research programs, this approach can inform policy decisions and benefit vulnerable populations whose comprehension of interrogation rights is encumbered by legalese. |
Elizabeth R. Schotter; Annie Jia Semantic and plausibility preview benefit effects in English: Evidence from eye movements Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 12, pp. 1839–1866, 2016. @article{Schotter2016a, Theories of preview benefit in reading hinge on integration across saccades and the idea that preview benefit is greater the more similar the preview and target are. Schotter (2013) reported preview benefit from a synonymous preview, but it is unclear whether this effect occurs because of similarity between the preview and target (i.e., integration), or because of contextual fit of the preview—synonyms satisfy both accounts. Studies in Chinese have found evidence for preview benefit for words that are unrelated to the target, but are contextually plausible (Yang, Li, Wang, Slattery, & Rayner, 2014; Yang, Wang, Tong, & Rayner, 2012), which is incompatible with an integration account but supports a contextual fit account. Here, we used plausible and implausible unrelated previews in addition to plausible synonym, antonym, and identical previews to further investigate these accounts for readers of English. Early reading measures were shorter for all plausible preview conditions compared to the implausible preview condition. In later reading measures, a benefit for the plausible unrelated preview condition was not observed. In a second experiment, we asked questions that probed whether the reader encoded the preview or target. Readers were more likely to report the preview when they had skipped the word and not regressed to it, and when the preview was plausible. Thus, under certain circumstances, the preview word is processed to a high level of representation (i.e., semantic plausibility) regardless of its relationship to the target, but its influence on reading is relatively short-lived, being replaced by the target word, when fixated. |
Elizabeth R. Schotter; Mallorie Leinenger Reversed preview benefit effects: Forced fixations emphasize the importance of parafoveal vision for efficient reading Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 42, no. 12, pp. 2039–2067, 2016. @article{Schotter2016, Current theories of eye movement control in reading posit that processing of an upcoming parafoveal preview word is used to facilitate processing of that word once it is fixated (i.e., as a foveal target word). This preview benefit is demonstrated by shorter fixation durations in the case of valid (i.e., identical or linguistically similar) compared with invalid (i.e., dissimilar) preview conditions. However, we suggest that processing of the preview can directly influence fixation behavior on the target, independent of similarity between them. In Experiment 1, unrelated high and low frequency words were used as orthogonally crossed previews and targets and we observed a reversed preview benefit for low frequency targets—shorter fixation durations with an invalid, higher frequency preview compared with a valid, low frequency preview. In Experiment 2, the target words were replaced with orthographically legal and illegal nonwords and we found a similar effect of preview frequency on fixation durations on the targets, as well as a bimodal distribution in the illegal nonword target conditions with a denser early peak for high than low frequency previews. In Experiment 3, nonwords were used as previews for high and low frequency targets, replicating standard findings that “denied” preview increases fixation durations and the influence of target properties. These effects can be explained by forced fixations, cases in which fixations on the target were shortened as a consequence of the timing of word recognition of the preview relative to the time course of saccade programming to that word from the prior one. That is, the preview word was (at least partially) recognized so that it should have been skipped, but the word could not be skipped because the saccade to that word was in a nonlabile stage. In these cases, the system preinitiates the subsequent saccade off the upcoming word to the following word and the intervening fixation is short. |

Discourse requires that we monitor information that is shared or mutually known, called "common ground." While many studies have examined the role of Theory of Mind (ToM) in such impairments, few have examined working memory (WM). Common ground impairments in ASD could reflect limitations in both WM and ToM. This study explored common ground use in youth ages 8-17 years with high-functioning ASD (n = 13) and typical development (n = 22); groups did not differ on age, gender, IQ, or standardized language. We tracked participants' eye movements while they performed a discourse task in which some information was known only to the participant (e.g., was privileged; a manipulation of ToM). In addition, the amount of privileged information varied (a manipulation of WM). All participants were slower to fixate the target when considering privileged information, and this effect was greatest during high WM load trials. Further, the ASD group was more likely to fixate competing (non-target) shapes. Predictors of fixation patterns included ASD symptomatology, language ability, ToM, and WM. Groups did not differ in ToM. Individuals with better WM fixated the target more rapidly, suggesting an association between WM capacity and efficient discourse. In addition to ToM knowledge, WM capacity constrains common ground representation and impacts pragmatic skills in ASD. Social impairments in ASD are thus associated with WM capacity, such that deficits in domain-general, nonsocial processes such as WM exert an influence during complex social interactions. |

Their effects are well-documented in eye movement studies, but pertinent evidence from neuroimaging primarily stem from single-word presentations. We investigated the effects of these variables during reading of whole sentences with simultaneous eye-tracking and functional magnetic resonance imaging (fixation-related fMRI). Increasing word length was associated with increasing activation in occipital areas linked to visual analysis. Additionally, length elicited a U-shaped modulation (i.e., least activation for medium-length words) within a brain stem region presumably linked to eye movement control. These effects, however, were diminished when accounting for multiple fixation cases. Increasing frequency was associated with decreasing activation within left inferior frontal, superior parietal, and occipito-temporal regions. The function of the latter region-hosting the putative visual word form area-was originally considered as limited to sublexical processing. An exploratory analysis revealed that increasing predictability was associated with decreasing activation within middle temporal and inferior frontal regions previously implicated in memory access and unification. The findings are discussed with regard to their correspondence with findings from single-word presentations and with regard to neurocognitive models of visual word recognition, semantic processing, and eye movement control during reading. |
Florian Schwarz False but slow: Evaluating statements with Non-referring definites Journal Article In: Journal of Semantics, vol. 33, pp. 177–214, 2016. @article{Schwarz2016, One central debate in the analysis of definite descriptions concerns the truth-value of sentences where there is no entity that meets the description in the definite. Classical Russellian accounts predict them to be plain false, whereas presuppositional accounts predict them to be infelicitous. Recent discussions have homed in on the factors that affect actual judgment behaviour in relation to the underlying status posited by different accounts. This article presents experimental evidence for a presuppositional view based on response times for judging statements with non-referring definites to be ‘false', which were longer relative to control statements where existence was asserted. I discuss the theoretical implications ofthese results, as well as of other findings from the literature, arguing that they support a presuppositional view of definites that sees the existence presupposition as conventionally encoded. The article also makes a methodological contribution, as systematic evidence on speakers' judgments in these cases turns out to be hard to come by. Finally, the results inform the more general issue of the online processes involved in the interpretation of presupposed, as opposed to asserted, content. |

The abnormality was most profound if the noun denoting the object could not be recognized. Even trials where the name of the target object was recognized but not retrieved triggered abnormal eye movements, demonstrating that retrieval failures can have underlying associative components despite intact comprehension of the corresponding noun. |
Mustafa Seckin; M. Marsel Mesulam; Joel L. Voss; Wei Huang; Emily J. Rogalski; Robert S. Hurley Am I looking at a cat or a dog? Gaze in the semantic variant of primary progressive aphasia is subject to excessive taxonomic capture Journal Article In: Journal of Neurolinguistics, vol. 37, pp. 68–81, 2016. @article{Seckin2016a, Object naming impairments or anomias are the most frequent symptom in aphasia, and can be caused by a variety of underlying neurocognitive mechanisms. Anomia in neurodegenerative or primary progressive aphasias (PPA) often appears to be based on taxonomic blurring of word meaning: words such as "dog" and "cat" are still recognized generically as referring to animals, but are no longer conceptually differentiated from each other, leading to coordinate errors in word-object matching. This blurring is the hallmark symptom of the "semantic variant" of PPA, who invariably show focal atrophy in the left anterior temporal lobe. In this study we used eye tracking to characterize information processing online (in real time) as non-aphasic controls, semantic and non-semantic PPA participants completed a word-to-object matching task. All participants (including controls) showed taxonomic capture of gaze, spending more time viewing foils that were from the same category as the target compared to unrelated foils, but capture was more extreme in the semantic PPA group. The semantic group showed heightened capture even on trials where they ultimately pointed to the correct target, demonstrating the superiority of eye movements over traditional testing methods in detecting subtle processing impairments. Heightened capture was primarily driven by a tendency to direct gaze back and forth, repeatedly, between a set of related foils on each trial, a behavior almost never shown by controls or non-semantic participants. This suggests semantic PPA participants were accumulating and weighing evidence for a probabilistic rather than definitive mapping between the noun and several candidate objects. Neurodegeneration in PPA thus appears to distort lexical concepts prior to extinguishing them altogether, causing uncertainty in recognition and word-object matching. |

Sheikh; Debra Titone The embodiment of emotional words in a second language: An eye-movement study Journal Article In: Cognition and Emotion, vol. 30, no. 3, pp. 488–500, 2016. @article{Sheikh2016, The hypothesis that word representations are emotionally impoverished in a second language (L2) has variable support. However, this hypothesis has only been tested using tasks that present words in isolation or that require laboratory-specific decisions. Here, we recorded eye movements for 34 bilinguals who read sentences in their L2 with no goal other than comprehension, and compared them to 43 first language readers taken from our prior study. Positive words were read more quickly than neutral words in the L2 across first-pass reading time measures. However, this emotional advantage was absent for negative words for the earliest measures. Moreover, negative words but not positive words were influenced by concreteness, frequency and L2 proficiency in a manner similar to neutral words. Taken together, the findings suggest that only negative words are at risk of emotional disembodiment during L2 reading, perhaps because a positivity bias in L2 experiences ensures that positive words are emotionally grounded. |

We used a visual-world paradigm with printed words, in which participants listened to a spoken target word embedded in a neutral spoken sentence while looking at a visual display of printed words. We examined whether a semantic competitor effect could be observed in the printed-word version of the visual-world paradigm. In Experiment 1, the relationship between the spoken target words and the printed words was manipulated so that they were semantically related (a semantic competitor), phonologically related (a phonological competitor), or unrelated (distractors). We found that the probability of fixations on semantic competitors was significantly higher than that of fixations on the distractors. In Experiment 2, the orthographic similarity between the spoken target words and their semantic competitors was manipulated to further examine whether the semantic competitor effect was modulated by orthographic similarity. We found significant semantic competitor effects regardless of orthographic similarity. Our study not only reveals that semantic information can affect visual attention, it also provides important new insights into the methodology employed to investigate the semantic processing of spoken words during spoken word recognition using the printed-word version of the visual-world paradigm. |

The role of parafoveal processing Journal Article In: Psychonomic Bulletin & Review, vol. 23, no. 5, pp. 1543–1552, 2016. @article{Sheridan2016, To examine the role of inter-word spaces during reading, we used a gaze-contingent boundary paradigm to manipulate parafoveal preview (i.e., valid vs. invalid preview) in a normal text condition that contained spaces (e.g., "John decided to sell the table") and in an unsegmented text condition that contained random numbers instead of spaces (e.g.,"John4decided8to5sell9the7table"). Preview effects on mean first-fixation durations were larger for normal than unsegmented text conditions, and survival analyses revealed a delay in the onset of both preview validity and word-frequency effects on first-fixation durations for unsegmented relative to normal text. Taken together with simulations that were conducted using the E-Z Reader model, the present findings indicated that unsegmented text deficits reflect disruptions to both parafoveal processing and lexical processing. We discuss the implications of our results for models of eye-movement control. |

Furthermore, changes in the perception of segmental contrasts due to L1 experience can influence L2 lexical access during comprehension. The present study investigates whether the effect of L1 experience on L2 processing seen at the segmental level extends to suprasegmental processing. In an eye-tracking task, Mandarin–English bilinguals heard an auditorily presented English word and selected which of two visually presented Chinese characters represented the correct Mandarin translation. The pitch contour of the spoken word was manipulated to either match or mismatch the lexical tone of the Mandarin translation. Results revealed that bilinguals were significantly faster to correctly identify the target and made earlier eye movements to targets when the suprasegmental information of the word spoken in English matched that of its Mandarin translation. The findings provide compelling evidence for bilinguals' sensitivity to suprasegmental tone information, even when listening to a non-tonal language. These results have important implications for the effect of L1 experience on L2 lexical access and language interaction in bilinguals, and are consistent with a highly interactive account of language processing. |

Slattery; Mark Yates; Bernhard Angele Interword and interletter spacing effects during reading revisited: Interactions with word and font characteristics Journal Article In: Journal of Experimental Psychology: Applied, vol. 22, no. 4, pp. 406–422, 2016. @article{Slattery2016, Despite the large number of eye movement studies conducted over the past 30+ years, relatively few have examined the influence that font characteristics have on reading. However, there has been renewed interest in 1 particular font characteristic, letter spacing, which has both theoretical (visual word recognition) and applied (font design) importance. Recently published results that letter spacing has a bigger impact on the reading performance of dyslexic children have perhaps garnered the most attention (Zorzi et al., 2012). Unfortunately, the effects of increased interletter spacing have been mixed with some authors reporting facilitation and others reporting inhibition (van den Boer & Hakvoort, 2015). The authors present findings from 3 experiments designed to resolve the seemingly inconsistent letter-spacing effects and provide clarity to researchers and font designers and researchers. The results indicate that the direction of spacing effects depend on the size of the default spacing chosen by font developers. Experiment 3 found that interletter spacing interacts with interword spacing, as the required space between words depends on the amount of space used between letters. Interword spacing also interacted with word type as the inhibition seen with smaller interword spacing was evident with nouns and verbs but not with function words. |
Manon W. Jones; Margaret J. Snowling; Kristina Moll What automaticity deficit? Activation of lexical information by readers with dyslexia in a rapid automatized naming Stroop-switch task Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 3, pp. 465–474, 2016. @article{Jones2016, Reading fluency is often predicted by rapid automatized naming (RAN) speed, which as the name implies, measures the automaticity with which familiar stimuli (e.g., letters) can be retrieved and named. Readers with dyslexia are considered to have less "automatized" access to lexical information, reflected in longer RAN times compared with nondyslexic readers. We combined the RAN task with a Stroop-switch manipulation to test the automaticity of dyslexic and nondyslexic readers' lexical access directly within a fluency task. Participants named letters in 10 × 4 arrays while eye movements and speech responses were recorded. Upon fixation, specific letter font colors changed from black to a different color, whereupon the participant was required to rapidly switch from naming the letter to naming the letter color. We could therefore measure reading group differences on "automatic" lexical processing, insofar as it was task-irrelevant. Readers with dyslexia showed obligatory lexical processing and a timeline for recognition that was overall similar to typical readers, but a delay emerged in the output (naming) phase. Further delay was caused by visual-orthographic competition between neighboring stimuli. Our findings outline the specific processes involved when researchers speak of "impaired automaticity" in dyslexic readers' fluency, and are discussed in the context of the broader literature in this field. |

Paterson Fast and slow readers and the effectiveness of the spatial frequency content of text : Evidence from reading times and eye movements Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 42, no. 8, pp. 1066–1071, 2016. @article{Jordan2016, Text contains a range of different spatial frequencies but the effectiveness of spatial frequencies for normal variations in skilled adult reading ability is unknown. Accordingly, young skilled adult readers showing fast or slow reading ability read sentences displayed as normal or filtered to contain only very low, low, medium, high, or very high spatial frequencies. Reading times and eye movement measures of fixations and saccades assessed the effectiveness of these displays for reading. Reading times showed that, for each reading ability, medium, high, and very high spatial frequencies were all more effective than lower spatial frequencies. Indeed, for each reading ability, reading times for normal text were maintained when text contained only medium, high, or very high spatial frequencies. However, reading times for normal text and for each spatial frequency were all substantially shorter for fast readers than for slow readers, and this advantage for fast readers was similar for normal, medium, high, and very high spatial frequencies but much larger for low and very low spatial frequencies. In addition, fast readers made fewer and shorter fixations, fewer and shorter regressions, and longer forward saccades, than slow readers, and these differences were generally similar in size for normal, medium, high, and very high spatial frequencies, but larger when spatial frequencies were lower. These findings suggest that fast and slow adult readers can each use a range of different spatial frequencies for reading but fast readers make more effective use of these spatial frequencies and especially those that are lower. |
Timothy R. Jordan; Jasmine Dixon; Victoria A. McGowan; Stoyan Kurtev; Kevin B. Paterson Effects of spatial frequencies on word identification by fast and slow readers: Evidence from eye movements Journal Article In: Frontiers in Psychology, vol. 7, pp. 1433, 2016. @article{Jordan2016b, Recent research has shown that differences in the effectiveness of spatial frequencies for fast and slow skilled adult readers may be an important component of differences in reading ability in the skilled adult reading population (Jordan, McGowan, Dixon, Kurtev & Paterson, 2016). But the precise nature of this influence on lexical processing during reading remains to be fully determined. Accordingly, to gain more insight into the use of spatial frequencies by skilled adult readers with fast and slow reading abilities, the present study looked at effects of spatial frequencies on the processing of specific target words in sentences. These target words were of either high or low lexical frequency and each sentence was displayed as normal or filtered to contain only very low, low, medium, high, or very high spatial frequencies. Eye movement behavior for target words was closest to normal for each reading ability when text was shown in medium or higher spatial frequency displays, although reading occurred for all spatial frequencies. Moreover, typical word frequency effects (the processing advantage for words with higher lexical frequencies) were observed for each reading ability across a broad range of spatial frequencies, indicating that many different spatial frequencies provide access to lexical representations during textual reading for both fast and slow skilled adult readers. Crucially, however, target word fixations were fewer and shorter for fast readers than for slow readers for all display types, and this advantage for fast readers appeared to be similar for normal, medium, high and very high spatial frequencies but larger for low and very low spatial frequencies. Therefore, although fast and slow skilled adult readers can both use a broad range of spatial frequencies when reading, fast readers make more effective use of these spatial frequencies, and especially those that are lower, when processing the identities of words. |
Timothy R. Jordan; Victoria A. McGowan; Stoyan Kurtev; Kevin B. Paterson A further look at postview effects in reading: An eye-movements study of influences from the left of fixation Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 42, no. 2, pp. 296–307, 2016. @article{Jordan2016a, When reading from left to right, useful information acquired during each fixational pause is widely assumed to extend 14 to 15 characters to the right of fixation but just 3 to 4 characters to the left, and certainly no further than the beginning of the fixated word. However, this leftward extent is strikingly small and seems inconsistent with other aspects of reading performance and with the general horizontal symmetry of visual input. Accordingly, 2 experiments were conducted to examine the influence of text located to the left of fixation during each fixational pause using an eye-tracking paradigm in which invisible boundaries were created in sentence displays. Each boundary corresponded to the leftmost edge of each word so that, as each sentence was read, the normal letter content of text to the left of each fixated word was corrupted by letter replacements that were either visually similar or visually dissimilar to the originals. The proximity of corrupted text to the left of fixation was maintained at 1, 2, 3, or 4 words from the left boundary of each fixated word. In both experiments, relative to completely normal text, reading performance was impaired when each type of letter replacement was up to 2 words to the left of fixated words but letter replacements further from fixation produced no impairment. These findings suggest that key aspects of reading are influenced by information acquired during each fixational pause from much further leftward than is usually assumed. Some of the implications of these findings for reading are discussed. |

This paper investigates stylistic simplification, a frequently hypothesised translation universal which involves, among others, breaking up long sentences in the process of translation (Laviosa 2002). One of the parameters commonly used in the investigations of simplification in translations is the average sentence length. In the present study we focus on sentence length to see if the tendency to incorporate stylistic simplification is equally present in the products of inter- and intralingual translation; what phases of the translation process are decisive for sentence length; whether the scope of consultation with the source text affects sentence length. Finally, we will try to verify if average sentence length is dependent on the level of translation experience. |

In 2 eye-tracking experiments, we found that comprehension of motion events involves the online construction of a spatial mental model that integrates language with the visual world. In Experiment 1, participants listened to sentences describing the movement of an agent to a goal while viewing visual scenes depicting the agent, goal, and empty space in between. Crucially, verbs suggested either upward (e.g., jump) or downward (e.g., crawl) paths. We found that in the rare event of fixating the empty space between the agent and goal, visual attention was biased upward or downward in line with the verb. In Experiment 2, visual scenes depicted a central obstruction, which imposed further constraints on the paths and increased the likelihood of fixating the empty space between the agent and goal. The results from this experiment corroborated and refined the previous findings. Specifically, eye-movement effects started immediately after hearing the verb and were in line with data from an additional mouse-tracking task that encouraged a more explicit spatial reenactment of the motion event. In revealing how event comprehension operates in the visual world, these findings suggest a mental simulation process whereby spatial details of motion events are mapped onto the world through visual attention. The strength and detectability of such effects in overt eye-movements is constrained by the visual world and the fact that perceivers rarely fixate regions of empty space. |
Efthymia C. Kapnoula; Bob McMurray Training alters the resolution of lexical interference: Evidence for plasticity of competition and inhibition Journal Article In: Journal of Experimental Psychology: General, vol. 145, no. 1, pp. 8–30, 2016. @article{Kapnoula2016, Language learning is generally described as a problem of acquiring new information (e.g., new words). However, equally important are changes in how the system processes known information. For example, a wealth of studies has suggested dramatic changes over development in how efficiently children recognize familiar words, but it is unknown what kind of experience-dependent mechanisms of plasticity give rise to such changes in real-time processing. We examined the plasticity of the language processing system by testing whether a fundamental aspect of spoken word recognition, lexical interference, can be altered by experience. Adult participants were trained on a set of familiar words over a series of 4 tasks. In the high-competition (HC) condition, tasks were designed to encourage coactivation of similar words (e.g., net and neck) and to require listeners to resolve this competition. Tasks were similar in the low-competition (LC) condition, but did not enhance this competition. Immediately after training, interlexical interference was tested using a visual world paradigm task. Participants in the HC group resolved interference to a fuller degree than those in the LC group, demonstrating that experience can shape the way competition between words is resolved. TRACE simulations showed that the observed late differences in the pattern of interference resolution can be attributed to differences in the strength of lexical inhibition. These findings inform cognitive models in many domains that involve competition/interference processes, and suggest an experience-dependent mechanism of plasticity that may underlie longer term changes in processing efficiency associated with both typical and atypical development. |
Hossein Karimi; Fernanda Ferreira Informativity renders a referent more accessible: Evidence from eyetracking Journal Article In: Psychonomic Bulletin & Review, vol. 23, no. 2, pp. 507–525, 2016. @article{Karimi2016, The amount of information attached to a noun phrase (henceforth, NP) has been shown to enhance accessibility and increase pronominal reference in language production. However, both the effect of information quantity on the comprehension of ambiguous pronouns and the time course of any informativity effect have been left unexplored. In two eyetracking experiments, we investigated how additional information on the part of NP referents influenced the resolution of following ambiguous pronouns. The results of the first experiment revealed an informativity effect, with more looks to the informationally richer referent than to the competitor. However, the effect of additional information emerged late in time when the referent was the object of the verb. The second experiment replicated the results of the first and also showed that, consistent with the online results, an ambiguous pronoun is interpreted as referring to the informationally richer NP in an offline, explicit pronoun resolution tas k. The results lend support to theories of language processing that assume that explicit information increases the accessibility of the associated concept, in contrast to approaches that assume that accessibility is associated with givenness. |
Benjawan Kasisopa; Ronan G. Reilly; Sudaporn Luksaneeyanawin; Denis Burnham Child readers' eye movements in reading Thai Journal Article In: Vision Research, vol. 123, pp. 8–19, 2016. @article{Kasisopa2016, It has recently been found that adult native readers of Thai, an alphabetic scriptio continua language, engage similar oculomotor patterns as readers of languages written with spaces between words; despite the lack of inter-word spaces, first and last characters of a word appear to guide optimal placement of Thai readers' eye movements, just to the left of word-centre. The issue addressed by the research described here is whether eye movements of Thai children also show these oculomotor patterns. Here the effect of first and last character frequency and word frequency on the eye movements of 18 Thai children when silently reading normal unspaced and spaced text was investigated. Linear mixed-effects model analyses of viewing time measures (first fixation duration, single fixation duration, and gaze duration) and of landing site location revealed that Thai children's eye movement patterns were similar to their adult counterparts. Both first character frequency and word frequency played important roles in Thai children's landing sites; children tended to land their eyes further into words, close to the word centre, if the word began with higher frequency first characters, and this effect was facilitated in higher frequency words. Spacing also facilitated more effective use of first character frequency and it also assisted in decreasing children's viewing time. The use of last-character frequency appeared to be a later development, affecting mainly single fixation duration and gaze duration. In general, Thai children use the same oculomotor control mechanisms in reading spaced and unspaced texts as Thai adults, who in turn have similar oculomotor control as readers of spaced texts. Thus, it appears that eye movements in reading converge on the optimal landing site using whatever cues are available to guide such placement. |
Jason J. Ki; Simon P. Kelly; Lucas C. Parra Attention strongly modulates reliability of neural responses to naturalistic narrative stimuli Journal Article In: Journal of Neuroscience, vol. 36, no. 10, pp. 3092–3101, 2016. @article{Ki2016, Attentional engagement is a major determinant of how effectively we gather information through our senses. Alongside the sheer growth in the amount and variety of information content that we are presented with through modern media, there is increased variability in the degree to which we "absorb" that information. Traditional research on attention has illuminated the basic principles of sensory selection to isolated features or locations, but it provides little insight into the neural underpinnings of our attentional engagement with modern naturalistic content. Here, we show in human subjects that the reliability of an individual's neural responses with respect to a larger group provides a highly robust index of the level of attentional engagement with a naturalistic narrative stimulus. Specifically, fast electroencephalographic evoked responses were more strongly correlated across subjects when naturally attending to auditory or audiovisual narratives than when attention was directed inward to a mental arithmetic task during stimulus presentation. This effect was strongest for audiovisual stimuli with a cohesive narrative and greatly reduced for speech stimuli lacking meaning. For compelling audiovisual narratives, the effect is remarkably strong, allowing perfect discrimination between attentional state across individuals. Control experiments rule out possible confounds related to altered eye movement trajectories or order of presentation. We conclude that reliability of evoked activity reproduced across subjects viewing the same movie is highly sensitive to the attentional state of the viewer and listener, which is aided by a cohesive narrative. |

Lemke Behavioural and eye-movement outcomes in response to text-based reading treatment for acquired alexia Journal Article In: Neuropsychological Rehabilitation, vol. 26, no. 1, pp. 60–86, 2016. @article{Kim2016, Text-based reading treatments, such as Multiple Oral Rereading (MOR) and Oral Reading for Language in Aphasia (ORLA) have been used successfully to remediate reading impairments in individuals with acquired alexia, but the mechanisms underlying such improvements are not well understood. In this study, an individual with acquired alexia who demonstrated reliance on a sub-lexical reading strategy (i.e., presence of spelling regularity effect and phonologically plausible errors) underwent 12 weeks of text-based reading treatment combining MOR and ORLA procedures. Behavioural assessments of single-word and text reading, along with eye-tracking assessments were conducted pre-treatment, post-treatment and at 5 month follow-up. Improved reading fluency (rate, accuracy) was observed for both trained and untrained passages. Evidence from behavioural and eye-tracking assessment suggested text-based reading treatment facilitated use of a lexical-semantic reading strategy. Increased frequency and lexicality effects, as well as a shift in initial landing position towards the centre of the word (the "optimal viewing position") were observed at post-treatment and follow-up assessments. These results demonstrate the potential utility of using eye movements as a parameter of interest in addition to traditional behavioural outcomes when investigating response to reading treatment. |
John Kingston; Joshua Levy; Amanda Rysling; Adrian Staub Eye movement evidence for an immediate Ganong effect Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 42, no. 12, pp. 1969–1988, 2016. @article{Kingston2016, Listeners tend to categorize an ambiguous speech sound so that it forms a word with its context (Ganong, 1980). This effect could reflect feedback from the lexicon to phonemic activation (McClelland & Elman, 1986), or the operation of a task-specific phonemic decision system (Norris, McQueen, & Cutler, 2000). Because the former account involves feedback between lexical and phonemic levels, it predicts that the lexicon's influence on phonemic decisions should be delayed and should gradually increase in strength. Previous response time experiments have not delivered a clear verdict as to whether this is the case, however. In 2 experiments, listeners' eye movements were tracked as they categorized phonemes using visually displayed response options. Lexically relevant information in the signal, the timing of which was confirmed by separate gating experiments, immediately increased eye movements toward the lexically supported response. This effect on eye movements then diminished over the course of the trial rather than continuing to increase. These results challenge the lexical feedback account. The present work also introduces a novel method for analyzing data from ‘visual-world' type tasks, designed to assess when an experimental manipulation influences the probability of an eye movement toward the target. |

Contrary to previous studies, convers ational materials with a natural variation in speech rate were used rather than lab-recorded stimuli that are subseque ntly artificially time-compressed. It was investigated whether older adults' speech recognition is more adversely affected by increased speech rate compared to younger and middle-aged adults, and which individual listener characteristics (e.g., hearing, fluid cognitive processi ng ability) predict the size of the speech rate effect on recognition performance. In an eye-trac king experiment, par-ticipants indicated with a mous e-click which visually presented words they recognized in a conversational fragment. Click response times , gaze, and pupil size data were analyzed. As expected, click response times and gaze behavi or were affected by speech rate, indicating that word recognition is more difficult if speec h rate is faster. Contrary to earlier findings, increased speech rate affecte d the age groups to the same extent. Fluid cognitive processing ability predicted general re cognition performance, but did not modulate the speech rate effect. These findings emphasize that earlier results of age by speech rate interactions mainly obtained with artificially speeded materials ma y not generalize to speech rate variation as encountered in conversational speech. |
Arnout W. Koornneef; Jakub Dotlačil; Paul W. Broek; Ted J. M. Sanders The influence of linguistic and cognitive factors on the time course of verb-based implicit causality Journal Article In: Quarterly Journal of Experimental Psychology, vol. 69, no. 3, pp. 455–481, 2016. @article{Koornneef2016, In three eye-tracking experiments the influence of the Dutch causal connective "want" (because) and the working memory capacity of readers on the usage of verb-based implicit causality was examined. Experiments 1 and 2 showed that although a causal connective is not required to activate implicit causality information during reading, effects of implicit causality surfaced more rapidly and were more pronounced when a connective was present in the discourse than when it was absent. In addition, Experiment 3 revealed that-in contrast to previous claims-the activation of implicit causality is not a resource-consuming mental operation. Moreover, readers with higher and lower working memory capacities behaved differently in a dual-task situation. Higher span readers were more likely to use implicit causality when they had all their working memory resources at their disposal. Lower span readers showed the opposite pattern as they were more likely to use the implicit causality cue in the case of an additional working memory load. The results emphasize that both linguistic and cognitive factors mediate the impact of implicit causality on text comprehension. The implications of these results are discussed in terms of the ongoing controversies in the literature-that is, the focusing-integration debate and the debates on the source of implicit causality. |
Nina S. Hsu; Jared M. Novick Dynamic engagement of cognitive control modulates recovery from misinterpretation during real-time language processing Journal Article In: Psychological Science, vol. 27, no. 4, pp. 572–582, 2016. @article{Hsu2016, Speech unfolds swiftly, yet listeners keep pace by rapidly assigning meaning to what they hear. Sometimes, though, initial interpretations turn out to be wrong. How do listeners revise misinterpretations of language input moment by moment to avoid comprehension errors? Cognitive control may play a role by detecting when processing has gone awry and then initiating behavioral adjustments accordingly. However, no research to date has investigated a cause-and-effect interplay between cognitive-control engagement and the overriding of erroneous interpretations in real time. Using a novel cross-task paradigm, we showed that Stroop-conflict detection, which mobilizes cognitive-control procedures, subsequently facilitates listeners' incremental processing of temporarily ambiguous spoken instructions that induce brief misinterpretation. When instructions followed incongruent Stroop items, compared with congruent Stroop items, listeners' eye movements to objects in a scene reflected more transient consideration of the false interpretation and earlier recovery of the correct one. Comprehension errors also decreased. Cognitive-control engagement therefore accelerates sentence-reinterpretation processes, even as linguistic input is still unfolding. |
Yi Ting Huang; Alison R. Arnold Word learning in linguistic context: Processing and memory effects Journal Article In: Cognition, vol. 156, pp. 71–87, 2016. @article{Huang2016, During language acquisition, children exploit syntactic cues within sentences to learn the meanings of words. Yet, it remains unknown how this strategy develops alongside an ability to access cues during real-time language comprehension. This study investigates how on-line sensitivity to syntactic cues impacts off-line interpretation and recall of word meanings. Adults and 5-year-olds heard novel words embedded in sentences that were (1) consistent with an agent-first bias (e.g., “The blicket will be eating the seal” → “the blicket” is an agent), (2) required revision of this bias (e.g., “The blicket will be eaten by the seal” → “the blicket” is a theme), or (3) weakened this bias through a familiar NP1 (e.g., “The seal will be eating/eaten by the blicket” → “the seal” is an agent or theme). Across both ages, eye-movements during sentences revealed decreased sensitivity to syntactic cues in contexts that required syntactic revision. In children, the magnitude of on-line sensitivity was positively associated with the accuracy of learning after the sentence. Parsing challenges during the word-learning task also negatively impacted children's later memory for word meanings during a recall task. Altogether, these results suggest that real-time demands impact word learning, through interpretive failures and memory interference. |
Falk Huettig; Esther Janse Individual differences in working memory and processing speed predict anticipatory spoken language processing in the visual world Journal Article In: Language, Cognition and Neuroscience, vol. 31, no. 1, pp. 80–93, 2016. @article{Huettig2016, Several mechanisms of predictive language processing have been proposed. The possible influence of mediating factors such as working memory and processing speed, however, has largely been ignored. We sought to find evidence for such an influence using an individual differences approach. 105 participants from 32–77 years of age received spoken instructions (e.g. “Kijk naar deCOM afgebeelde pianoCOM”– look at the displayed piano) while viewing 4 objects. Articles (Dutch “het” or “de”) were gender-marked such that the article agreed in gender only with the target. Participants could thus use article gender information to predict the target. Multiple regression analyses showed that enhanced working memory abilities and faster processing speed predicted anticipatory eye movements. Models of predictive language processing therefore must take mediating factors into account. More generally, our results are consistent with the notion that working memory grounds language in space and time, linking linguistic and visual–spatial representations. |
Jukka Hyönä; Miia Ekholm Background speech effects on sentence processing during reading: An eye movement study Journal Article In: PLoS ONE, vol. 11, no. 3, pp. e0152133, 2016. @article{Hyoenae2016, Effects of background speech on reading were examined by playing aloud different types of background speech, while participants read long, syntactically complex and less complex sentences embedded in text. Readers' eye movement patterns were used to study online sentence comprehension. Effects of background speech were primarily seen in rereading time. In Experiment 1, foreign-language background speech did not disrupt sentence pro- cessing. Experiment 2 demonstrated robust disruption in reading as a result of semantically and syntactically anomalous scrambled background speech preserving normal sentence- like intonation. Scrambled speech that was constructed from the text to-be read did not dis- rupt reading more than scrambled speech constructed from a different, semantically unre- lated text. Experiment 3 showed that scrambled speech exacerbated the syntactic complexity effect more than coherent background speech, which also interfered with read- ing. Experiment 4 demonstrated that both semantically and syntactically anomalous speech produced no more disruption in reading than semantically anomalous but syntactically cor- rect background speech. The pattern of results is best explained by a semantic account that stresses the importance of similarity in semantic processing, but not similarity in semantic content, between the reading task and background speech.
