Gregory D. Keating Sensitivity to violation of gender agreement in native and nonnative Spanish Journal Article In: Language Learning, vol. 59, no. 3, pp. 503 – 535, 2009. @article{Keating2009, This article reports the results of an eye‐tracking experiment that investigated the effects of structural distance on readers' sensitivity to violations of Spanish gender agreement during online sentence comprehension. The study tracked the eye movements of native Spanish speakers and English‐speaking learners of Spanish as they read sentences that contained nouns modified by postnominal adjectives located in three syntactic domains: (a) in the DP, (b) in the VP, or (c) in a subordinate clause. In half of the sentences in each condition, adjectives agreed with the noun in gender, and in half, they did not. The results indicate that gender agreement is acquirable in adulthood, contra the failed functional features hypothesis, and that the distance that separates nouns and adjectives affects the detection of gender anomalies in the second language. The findings support Clahsen and Felser's (2006a) shallow structure hypothesis, as it pertains to morphological processing. |
Pia Knoeferle; Matthew W. Crocker Constituent order and semantic parallelism in online comprehension Eye- tracking evidence from German Journal Article In: Quarterly Journal of Experimental Psychology, vol. 62, no. 12, pp. 2338–2371, 2009. @article{Knoeferle2009, Reading times for the second conjunct of and-coordinated clauses are faster when the second conjunct parallels the first conjunct in its syntactic or semantic (animacy) structure than when its structure differs (Frazier, Munn, & Clifton, 2000; Frazier, Taft, Roeper, & Clifton, 1984). What remains unclear, however, is the time course ofparallelism effects, their scope, and the kinds oflinguistic information to which they are sensitive. Findings from the first two eye-tracking experiments revealed incremental constituent order parallelism across the board – both during structural disambiguation (Experiment 1) and in sentences with unambiguously case-marked constituent order (Experiment 2), as well as for both marked and unmarked constituent orders (Experiments 1 and 2). Findings from Experiment 3 revealed effects of both constituent order and subtle semantic (noun phrase similarity) parallelism. Together our findings provide evidence for an across-the-board account of parallelism for processing and coordinated clauses, in which both constituent order and semantic aspects of representations contribute towards incremental parallelism effects. We discuss our findings in the context ofexisting findings on parallelism and priming, as well as mechanisms ofsentence processing. |
Timothy L. Hodgson; Benjamin A. Parris; Nicola J. Gregory; Tracey Jarvis The saccadic Stroop effect: Evidence for involuntary programming of eye movements by linguistic cues Journal Article In: Vision Research, vol. 49, no. 5, pp. 569–574, 2009. @article{Hodgson2009, The effect of automatic priming of behaviour by linguistic cues is well established. However, as yet these effects have not been directly demonstrated for eye movement responses. We investigated the effect of linguistic cues on eye movements using a modified version of the Stroop task in which a saccade was made to the location of a peripheral colour patch which matched the "ink" colour of a centrally presented word cue. The words were either colour words ("red", "green", "blue", "yellow") or location words ("up", "down", "left", "right"). As in the original version of the Stroop task the identity of the word could be either congruent or incongruent with the response location. The results showed that oculomotor programming was influenced by word identity, even though the written word provided no task relevant information. Saccade latency was increased on incongruent trials and an increased frequency of error saccades was observed in the direction congruent with the word identity. The results argue against traditional distinctions between reflexive and voluntary programming of saccades and suggest that linguistic cues can also influence eye movement programming in an automatic manner. |
Yufen Hsieh; Julie E. Boland; Yaxu Zhang; Ming Yan Limited syntactic parallelism in Chinese ambiguity resolution Journal Article In: Language and Cognitive Processes, vol. 24, no. 7-8, pp. 1227–1264, 2009. @article{Hsieh2009c, Using the stop-making-sense paradigm (Boland, Tanenhaus, Garnsey, & Carlsen, 1995) and eye-tracking during reading, we examined the processing of the Chinese Verb NP1 de NP2 construction, which is temporarily ambiguous between a complement clause (CC) analysis and a relative clause (RC) analysis. resolving the ambiguity as the more complex, less preferred CC was costly under come conditions but not under others. We took this as evidence for a limited parallel processor, such as Tabor and Hutchins' (2004) SOPARSE, that maintains multiple syntaxctic analyses across several words of a sentence when the structures are each supported by the available constraints. |
Lynn Huestegge; Ralph Radach; Daniel Corbic; Sujata M. Huestegge Oculomotor and linguistic determinants of reading development: A longitudinal study Journal Article In: Vision Research, vol. 49, pp. 2948–2959, 2009. @article{Huestegge2009a, We longitudinally assessed the development of oculomotor control in reading from second to fourth grade by having children read sentences with embedded target words of varying length and frequency. Additionally, participants completed oculomotor (pro-/anti-saccades) and linguistic tasks (word/picture naming), the latter containing the same item material as the reading task. Results revealed a 36% increase of reading efficiency. Younger readers utilized a global refixation strategy to gain more time for word decoding. Linguistic rather than oculomotor skills determined the development of reading abilities, although naming latencies of fourth graders did not reliably reflect word decoding processes in normal sentence reading. |
Albrecht W. Inhoff; Seth N. Greenberg; Matthew S. Solomon; Chin-An Wang Word integration and regression programming during reading: A test of the E-Z reader 10 model Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 5, pp. 1571–1584, 2009. @article{Inhoff2009, Participants read sentences with two types of target nouns, one that did and one that did not require a determiner to form a legal verb-noun phrase sequence. Sentences were presented with and without the critical determiner to create a local noun integration difficulty when a required determiner was missing. The absence of a required determiner did not influence 1st-pass reading of the verb, the noun, and the posttarget word. It did, however, have a profound effect on 2nd-pass reading. All three words were a likely target of a regression when a required determiner was missing, and the noun and the posttarget word were likely sources of a regression. These results are consistent with novel E-Z reader model assumptions, according to which identification of the noun should be followed by its integration, and integration difficulties can lead to the initiation of a regression to the noun. However, integration difficulties influenced eye movements earlier and later than predicted by the new model. |
Timo Järvilehto; Veli-Matti Nurkkala; Kyösti Koskela The role of anticipation in reading Journal Article In: Pragmatics & Cognition, vol. 17, no. 3, pp. 509–526, 2009. @article{Jaervilehto2009, Learning in educational settings most o en emphasizes declarative and proce- dural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: Perceptual learning. Here we describe research that combines principles of perceptual learning with computer technology to address persistent di culties in mathematics learning. We report three experiments in which we developed and tested perceptual learning modules (PLMs) to address issues of structure extraction and uency in relation to algebra and fractions. PLMs focus students' learning on recognizing and discriminating, or map- ping key structures across di erent representations or transformations. Results showed signi cant and persisting learning gains for students using PLMs. PLM technology o ers promise for addressing neglected components of learning: Pat- tern recognition, structural intuition, and uency. Using PLMs as a complement to other modes of instruction may allow students to overcome chronic problems in learning |
Victor Kuperman; Robert Schreuder; Raymond Bertram; R. Harald Baayen Reading polymorphemic Dutch compounds: toward a multiple route model of lexical processing. Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 3, pp. 876–895, 2009. @article{Kuperman2009, This article reports an eye-tracking experiment with 2,500 polymorphemic Dutch compounds presented in isolation for visual lexical decision while readers' eye movements were registered. The authors found evidence that both full forms of compounds (dishwasher) and their constituent morphemes (e.g., dish, washer) and morphological families of constituents (sets of compounds with a shared constituent) played a role in compound processing. They observed simultaneous effects of compound frequency, left constituent frequency, and family size early (i.e., before the whole compound has been scanned) and also observed effects of right constituent frequency and family size that emerged after the compound frequency effect. The temporal order of these and other observed effects goes against assumptions of many models of lexical processing. The authors propose specifications for a new multiple-route model of polymorphemic compound processing that is based on time-locked, parallel, and interactive use of all morphological cues as soon as they become even partly available to the visual uptake system. |
Yoonhyoung Lee; Kichun Nam; Peter C. Gordon Processing of the Korean Eojoel ambiguity Journal Article In: Journal of Psycholinguistic Research, vol. 38, no. 4, pp. 345–362, 2009. @article{Lee2009, Korean writing is a syllabary where spaces occur between phrases rather than between words. This characteristic of Korean allows different types of information in Korean sentences to be dissociated in ways that are not possible in the languages that have been the focus of most psycholinguistic research, thereby providing new opportunities to investigate mechanisms of ambiguity resolution during sentence comprehension. In experiments using eye-tracking and self-paced reading, we examined how readers resolve the Eojoel ambiguity, where the grouping of syllables is ambiguous with respect to whether a phrase-final syllable is a case marker or a part of a word. This Eojoel ambiguity offers an opportunity to test how relative frequency of the lexical entries and complexity of morphological decomposition affect ambiguity resolution. Overall, the results of the experiments presented here showed that readers noticed and processed the Eojoel ambiguity very rapidly using information about the relative frequency of alternative interpretations, while the complexity of the morphological decomposition had little effect. These results are discussed in terms of constraint-based accounts (MacDonald et al. Psychol Rev 101:676-703, 1994) of ambiguity resolution. |
Roger P. Levy; Klinton Bicknell; Timothy J. Slattery; Keith Rayner Eye movement evidence that readers maintain and act on uncertainty about past linguistic input Journal Article In: Proceedings of the National Academy of Sciences, vol. 106, no. 50, pp. 21086–21090, 2009. @article{Levy2009, In prevailing approaches to human sentence comprehension, the outcome of the word recognition process is assumed to be a categorical representation with no residual uncertainty. Yet perception is inevitably uncertain, and a system making optimal use of available information might retain this uncertainty and interactively recruit grammatical analysis and subsequent perceptual input to help resolve it. To test for the possibility of such an interaction, we tracked readers' eye movements as they read sentences constructed to vary in (i) whether an early word had near neighbors of a different grammatical category, and (ii) how strongly another word further downstream cohered grammatically with these potential near neighbors. Eye movements indicated that readers maintain uncertain beliefs about previously read word identities, revise these beliefs on the basis of relative grammatical consistency with subsequent input, and use these changing beliefs to guide saccadic behavior in ways consistent with principles of rational probabilistic inference. |
Maya R. Libben; Debra A. Titone Bilingual lexical access in context: Evidence from eye movements during reading Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 35, no. 2, pp. 381–390, 2009. @article{Libben2009, Current models of bilingualism (e.g., BIA+) posit that lexical access during reading is not language selective. However, much of this research is based on the comprehension of words in isolation. The authors investigated whether nonselective access occurs for words embedded in biased sentence contexts (e.g., A. I. Schwartz & J. F. Kroll, 2006). Eye movements were recorded as French-English bilinguals read English sentences containing cognates (e.g., piano), interlingual homographs (e.g., coin, meaning corner in French), or matched control words. Sentences provided a low or high semantic constraint for target-language meanings. Both early-stage comprehension measures (e.g., first fixation duration, gaze duration, and skipping) and late-stage comprehension measures (e.g., go-past time and total reading time) showed significant cognate facilitation and interlingual homograph interference for low-constraint sentences. For high-constraint sentences, however, only early-stage comprehension measures were consistent with nonselective access. There was no evidence of cognate facilitation or interlingual homograph interference for late-stage comprehension measures. Thus, nonselective bilingual lexical access at early stages of comprehension is rapidly resolved in semantically biased contexts at later stages of comprehension. |
Keith Rayner; Monica S. Castelhano; Jinmian Yang Eye movements and the perceptual span in older and younger readers Journal Article In: Psychology and Aging, vol. 24, no. 3, pp. 755–760, 2009. @article{Rayner2009a, The size of the perceptual span (or the span of effective vision) in older readers was examined with the moving window paradigm (G. W. McConkie & K. Rayner, 1975). Two experiments demonstrated that older readers have a smaller and more symmetric span than that of younger readers. These 2 characteristics (smaller and more symmetric span) of older readers may be a consequence of their less efficient processing of nonfoveal information, which results in a riskier reading strategy. |
Annie Roy-Charland; Jean Saint-Aubin; Michael A. Lawrence; Raymond M. Klein Solving the chicken-and-egg problem of letter detection and fixation duration in reading Journal Article In: Attention, Perception, and Psychophysics, vol. 71, no. 7, pp. 1553–1562, 2009. @article{RoyCharland2009, When asked to detect target letters while reading a text, participants miss more letters in frequent function words than in less frequent content words. According to the truncation assumption that characterizes most models of this effect, misses occur when word-processing time is shorter than letter-processing time. Fixation durations for detections and omissions were compared with fixation durations from a baseline condition when participants were searching for a target letter embedded in different words. Although, as predicted by truncation, fixation durations were longer for detections than for omissions, fixation durations for detections were also longer than those for the same words in the baseline condition, demonstrating that longer fixation durations when targets are detected are more likely to be due to demands associated with producing a detection response than to truncation. Also, contrary to predictions from the truncation assumption, the standard deviation of fixation durations for detections was larger than that from the baseline condition. |
Craig G. Chambers; Hilary Cooke Lexical competition during second-language listening: Sentence context, but not proficiency, constrains interference from the native lexicon Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 35, no. 4, pp. 1029–1040, 2009. @article{Chambers2009, A spoken language eye-tracking methodology was used to evaluate the effects of sentence context and proficiency on parallel language activation during spoken language comprehension. Nonnative speakers with varying proficiency levels viewed visual displays while listening to French sentences (e.g., Marie va décrire la poule [Marie will describe the chicken]). Displays depicted several objects including the final noun target (chicken) and an interlingual near-homophone (e.g., pool) whose name in English is phonologically similar to the French target (poule). Listeners' eye movements reflected temporary consideration of the interlingual competitor when hearing the target noun, demonstrating cross-language lexical competition. However, competitor fixations were dramatically reduced when prior sentence information was incompatible with the competitor (e.g., Marie va nourrir... [Marie will feed...]). In contrast, interlingual competition from English did not vary according to participants' rated proficiency in French, even though proficiency reliably predicted other aspects of processing behavior, suggesting higher proficiency in the active language does not provide a significant independent source of control over interlingual competition. The results provide new insights into the nature of parallel language activation in naturalistic sentential contexts. |
Claudia Felser; Mikako Sato; Nicholas Bertenshaw The on-line application of binding principle A in english as a second language Journal Article In: Bilingualism: Language and Cognition, vol. 12, no. 4, pp. 485–502, 2009. @article{Felser2009, We report the results from two experiments investigating proficient Japanese-speaking learners' processing of reflexive object pronouns in English as a second language (L2). Experiment 1 used a timed grammaticality judgement task to assess learners' sensitivity to binding Principle A under processing pressure, and Experiment 2 investigated the time-course of reflexive anaphor resolution during L2 reading using the eye-movement monitoring technique. Taken together, our results show that despite having demonstrated native-like knowledge of reflexive binding in corresponding untimed tasks, the learners processed English reflexives differently from native speakers in that they took into consideration a matching discourse-prominent but binding-theoretically inappropriate antecedent when first encountering a reflexive. This suggests that unlike what has been reported in corresponding monolingual processing research (Sturt, 2003), initial antecedent search in L2 English is not constrained by binding Principle A. © 2009 Cambridge University Press. |
Gary Feng Mixed responses: Why readers spend less time at unfavorable landing positions Journal Article In: Journal of Eye Movement Research, vol. 3, no. 2, pp. 1–26, 2009. @article{Feng2009, This paper investigates why the average fixation duration tends to decrease from the center to the two ends of a word. Specifically, it examines (a) whether unfavorable landing positions trigger a corrective mechanism, (b) whether the triggering is based on the internal efference copy mechanism, and (c) whether the corrective mechanism is specific to fixations that missed their targeted words. To estimate the mean and proportion of the corrective fixations, a 3-parameter mixture model was fitted to distributions of first fixation duration from two large eye movement databases in studies 1 and 2. Study 3 experimentally created mislocated fixations using a gaze-contingent screen shift paradigm. There is little evidence for the efference copy mechanism and limited support for the mislocated fixations hypothesis. Overall, data suggest a process that terminates fixations sooner than would during normal reading; it is triggered by the visual input during a fixation, and is flexibly engaged at eccentric landing positions and in reading short words. Implications to theories of reading eye movements are discussed. |

Gerry T. M. Altmann; Yuki Kamide Discourse-mediation of the mapping between language and the visual world: Eye movements and mental representation Journal Article In: Cognition, vol. 111, no. 1, pp. 55–71, 2009. @article{Altmann2009, Two experiments explored the mapping between language and mental representations of visual scenes. In both experiments, participants viewed, for example, a scene depicting a woman, a wine glass and bottle on the floor, an empty table, and various other objects. In Experiment 1, participants concurrently heard either 'The woman will put the glass on the table' or 'The woman is too lazy to put the glass on the table'. Subsequently, with the scene unchanged, participants heard that the woman 'will pick up the bottle, and pour the wine carefully into the glass.' Experiment 2 was identical except that the scene was removed before the onset of the spoken language. In both cases, eye movements after 'pour' (anticipating the glass) and at 'glass' reflected the language-determined position of the glass, as either on the floor, or moved onto the table, even though the concurrent (Experiment 1) or prior (Experiment 2) scene showed the glass in its unmoved position on the floor. Language-mediated eye movements thus reflect the real-time mapping of language onto dynamically updateable event-based representations of concurrently or previously seen objects (and their locations). |
Jens Bölte; Andrea Böhl; Christian Dobel; Pienie Zwitserlood Effects of referential ambiguity, time constraints and addressee orientation on the production of morphologically complex words Journal Article In: European Journal of Cognitive Psychology, vol. 21, no. 8, pp. 1166–1199, 2009. @article{Boelte2009, In five experiments, participants were asked to describe unambiguously a target picture in a picture-picture paradigm. In the same-category condition, target (e. g., water bucket) and distractor picture (e. g., ice bucket) had identical names when their preferred, morphologically simple, name was used (e. g., bucket). The ensuing lexical ambiguity could be resolved by compound use (e. g., water bucket). Simple names sufficed as means of specification in other conditions, with distractors identical to the target, completely unrelated, or geometric figures. With standard timing parameters, participants produced mainly ambiguous answers in Experiment 1. An increase in available processing time hardly improved unambiguous responding (Experiment 2). A referential communication instruction (Experiment 3) increased the number of compound responses considerably, but morphologically simple answers still prevailed. Unambiguous responses outweighed ambiguous ones in Experiment 4, when timing parameters were further relaxed. Finally, the requirement to name both objects resulted in a nearly perfect ambiguity resolution (Experiment 5). Together, the results showed that speakers overcome lexical ambiguity only when time permits, when an addressee perspective is given and, most importantly, when their own speech overtly signals the ambiguity. |
Sarah Brown-Schmidt The role of executive function in perspective taking during online language comprehension Journal Article In: Psychonomic Bulletin & Review, vol. 16, no. 5, pp. 893–900, 2009. @article{BrownSchmidt2009, During conversation, interlocutors build on the set of shared beliefs known as common ground. Although there is general agreement that interlocutors maintain representations of common ground, there is no consensus regarding whether common-ground representations constrain initial language interpretation processes. Here, I propose that executive functioning–specifically, failures in inhibition control–can account for some occasional insensitivities to common-ground information. The present article presents the results of an experiment that demonstrates that individual differences in inhibition control determine the degree to which addressees successfully inhibit perspective-inappropriate interpretations of temporary referential ambiguities in their partner's speech. Whether mentioned information was grounded or not also played a role, suggesting that addressees may show sensitivity to common ground only when it is established collaboratively. The results suggest that, in conversation, perspective information routinely guides online language processing and that occasional insensitivities to perspective can be attributed partly to difficulties in inhibiting perspective-inappropriate interpretations. |
Sarah Brown-Schmidt Partner-specific interpretation of maintained referential precedents during interactive dialog Journal Article In: Journal of Memory and Language, vol. 61, no. 2, pp. 171–190, 2009. @article{BrownSchmidt2009a, In dialog settings, conversational partners converge on similar names for referents. These lexically entrained terms [Garrod, S., & Anderson, A. (1987). Saying what you mean in dialog: A study in conceptual and semantic co-ordination. Cognition, 27, 181-218] are part of the common ground between the particular individuals who established the entrained term [Brennan, S. E., & Clark, H. H. (1996). Conceptual pacts and lexical choice in conversation. Journal of Experimental Psychology: Learning, Memory, and Cognition, 22, 1482-1493], and are thought to be encoded in memory with a partner-specific cue. Thus far, analyses of the time-course of interpretation suggest that partner-specific information may not constrain the initial interpretation of referring expressions [Barr, D. J., & Keysar, B. (2002). Anchoring comprehension in linguistic precedents. Journal of Memory and Language, 46, 391-418; Kronmüller, E., & Barr, D. J. (2007). Perspective-free pragmatics: Broken precedents and the recovery-from-preemption hypothesis. Journal of Memory and Language, 56, 436-455]. However, these studies used non-interactive paradigms, which may limit the use of partner-specific representations. This article presents the results of three eye-tracking experiments. Experiment 1a used an interactive conversation methodology in which the experimenter and participant jointly established entrained terms for various images. On critical trials, the same experimenter, or a new experimenter described a critical image using an entrained term, or a new term. The results demonstrated an early, on-line partner-specific effect for interpretation of entrained terms, as well as preliminary evidence for an early, partner-specific effect for new terms. Experiment 1b used a non-interactive paradigm in which participants completed the same task by listening to image descriptions recorded during Experiment 1a; the results showed that partner-specific effects were eliminated. Experiment 2 replicated the partner-specific findings of Experiment 1a with an interactive paradigm and scenes that contained previously unmentioned images. The results suggest that partner-specific interpretation is most likely to occur in interactive dialog settings; the number of critical trials and stimulus characteristics may also play a role. The results are consistent with a large body of work demonstrating that the language processing system uses a rich source of contextual and pragmatic representations to guide on-line processing decisions. |
Stefan Grondelaers; Dirk Speelman; Denis Drieghe; Marc Brysbaert; Dirk Geeraerts In: Acta Psychologica, vol. 130, no. 2, pp. 1–33, 2009. @article{Grondelaers2009, This paper reports on the ways in which new entities are introduced into discourse. First, we present the evidence in support of a model of indefinite reference processing based on three principles: the listener's ability to make predictive inferences in order to decrease the unexpectedness of upcoming words, the availability to the speaker of grammatical constructions that customize predictive inferences, and the use of "expectancy monitors" to signal and facilitate the introduction of highly unpredictable entities. We provide evidence that one of these expectancy monitors in Dutch is the post-verbal variant of existential er (the equivalent of the unstressed existential "there" in English). In an eye-tracking experiment we demonstrate that the presence of er decreases the processing difficulties caused by low subject expectancy. A corpus-based regression analysis subsequently confirms that the production of er is determined almost exclusively by seven parameters of low subject expectancy. Together, the comprehension and production data suggest that while existential er functions as an expectancy monitor in much the same way as speech disfluencies (hesitations, pauses and filled pauses), er is a higher-level expectancy monitor because it is available in spoken and written discourse and because it is produced more systematically than any disfluency. |
Tuomo Häikiö; Raymond Bertram; Jukka Hyönä; Pekka Niemi Development of the letter identity span in reading: Evidence from the eye movement moving window paradigm Journal Article In: Journal of Experimental Child Psychology, vol. 102, no. 2, pp. 167–181, 2009. @article{Haeikioe2009, By means of the moving window paradigm, we examined how many letters can be identified during a single eye fixation and whether this letter identity span changes as a function of reading skill. The results revealed that 8-year-old Finnish readers identify approximately 5 characters, 10-year-old readers identify approximately 7 characters, and 12-year-old and adult readers identify approximately 9 characters to the right of fixation. Comparison with earlier studies revealed that the letter identity span is smaller than the span for identifying letter features and that it is as wide in Finnish as in English. Furthermore, the letter identity span of faster readers of each age group was larger than that of slower readers, indicating that slower readers, unlike faster readers, allocate most of their processing resources to foveally fixated words. Finally, slower second graders were largely not disrupted by smaller windows, suggesting that their word decoding skill is not yet fully automatized. |
Sébastien Miellet; Patrick J. O'Donnell; Sara C. Sereno Parafoveal magnification: Visual acuity does not modulate the perceptual span in reading Journal Article In: Psychological Science, vol. 20, no. 6, pp. 721–728, 2009. @article{Miellet2009, Models of eye guidance in reading rely on the concept of the perceptual span—the amount of information perceived during a single eye fixation, which is considered to be a consequence of visual and attentional constraints. To directly investigate attentional mechanisms underlying the perceptual span, we implemented a new reading paradigm—parafoveal magnification (PM)— that compensates for how visual acuity drops off as a function of retinal eccentricity. On each fixation and in real time, parafoveal text is magnified to equalize its perceptual impact with that of concurrent foveal text. Experiment 1 demonstrated that PM does not increase the amount of text that is processed, supporting an attentional-based account ofeye movements in reading. Experiment 2 explored a contentious issue that differentiates competing models of eye movement control and showed that, even when parafoveal information is enlarged, visual attention in reading is allocated in a serial fashion from word to word. |
Holger Mitterer; James M. McQueen Processing reduced word-forms in speech perception using probabilistic knowledge about speech production Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 1, pp. 244–263, 2009. @article{Mitterer2009, Two experiments examined how Dutch listeners deal with the effects of connected-speech processes, specifically those arising from word-final /t/ reduction (e.g., whether Dutch [tas] is tas, bag, or a reduced-/t/ version of tast, touch). Eye movements of Dutch participants were tracked as they looked at arrays containing 4 printed words, each associated with a geometrical shape. Minimal pairs (e.g., tas/tast) were either both above (boven) or both next to (naast) different shapes. Spoken instructions (e.g., “Klik op het woordje tas boven de ster,” [Click on the word bag above the star]) thus became unambiguous only on their final words. Prior to disambiguation, listeners' fixations were drawn to /t/-final words more when boven than when naast followed the ambiguous sequences. This behavior reflects Dutch speech- production data: /t/ is reduced more before /b/ than before /n/. We thus argue that probabilistic knowledge about the effect of following context in speech production is used prelexically in perception to help resolve lexical ambiguities caused by continuous-speech processes. |
Antje Nuthmann; Ralf Engbert Mindless reading revisited: An analysis based on the SWIFT model of eye-movement control Journal Article In: Vision Research, vol. 49, no. 3, pp. 322–336, 2009. @article{Nuthmann2009, In this article, we revisit the mindless reading paradigm from the perspective of computational modeling. In the standard version of the paradigm, participants read sentences in both their normal version as well as the transformed (or mindless) version where each letter is replaced with a z. z-String scanning shares the oculomotor requirements with reading but none of the higher-level lexical and semantic processes. Here we use the z-string scanning task to validate the SWIFT model of saccade generation [Engbert, R., Nuthmann, A., Richter, E., & Kliegl, R. (2005). SWIFT: A dynamical model of saccade generation during reading. Psychological Review, 112(4), 777-813] as an example for an advanced theory of eye-movement control in reading. We test the central assumption of spatially distributed processing across an attentional gradient proposed by the SWIFT model. Key experimental results like prolonged average fixation durations in z-string scanning compared to normal reading and the existence of a string-length effect on fixation durations and probabilities were reproduced by the model, which lends support to the model's assumptions on visual processing. Moreover, simulation results for patterns of regressive saccades in z-string scanning confirm SWIFT's concept of activation field dynamics for the selection of saccade targets. |
Antje Nuthmann; Reinhold Kliegl An examination of binocular reading fixations based on sentence corpus data Journal Article In: Journal of Vision, vol. 9, no. 5, pp. 31–31, 2009. @article{Nuthmann2009a, Binocular eye movements of normal adult readers were examined as they read single sentences. Analyses of horizontal and vertical fixation disparities indicated that the most prevalent type of disparate fixation is crossed (i.e., the left eye is located further to the right than the right eye) while the left eye frequently fixates somewhat above the right eye. The Gaussian distribution of the binocular fixation point peaked 2.6 cm in front of the plane of text, reflecting the prevalence of horizontally crossed fixations. Fixation disparity accumulates during the course of successive saccades and fixations within a line of text, but only to an extent that does not compromise single binocular vision. In reading, the version and vergence system interact in a way that is qualitatively similar to what has been observed in simple nonreading tasks. Finally, results presented here render it unlikely that vergence movements in reading aim at realigning the eyes at a given saccade target word. |

Davis; Manuel Perea; Joana Acha Re(de)fining the orthographic neighborhood: The role of addition and deletion neighbors in lexical decision and reading Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 5, pp. 1550–1570, 2009. @article{Davis2009, The influence of addition and deletion neighbors on visual word identification was investigated in four experiments. Experiments 1 and 2 used Spanish stimuli. In Experiment 1, lexical decision latencies were slower and less accurate for words and nonwords with higher-frequency deletion neighbors (e.g., jugar in juzgar), relative to control stimuli. Experiment 2 showed a similar interference effect for words and nonwords with higher-frequency addition neighbors (e.g., conejo, which has the addition neighbor consejo), relative to control stimuli. Experiment 3 replicated this addition neighbor interference effect in a lexical decision experiment with English stimuli. Across all three experiments, interference effects were always evident for addition/deletion neighbors with word-outer overlap, usually present for those with word-initial overlap, but never present for those with word-final overlap. Experiment 4 replicated the addition/deletion neighbor inhibitory effects in a Spanish sentence reading task in which the participants' eye movements were monitored. These findings suggest that conventional orthographic neighborhood metrics should be redefined. In addition to its methodological implications, this conclusion has significant theoretical implications for input coding schemes and the mechanisms underlying word recognition. |

This manipulation allowed us to test a basic prediction derived from the qualitatively different representational framework that supports the view of different organizational principles for concrete and abstract words in semantic memory. Our results confirm the assumption of a primary organizational principle based on association for abstract words, different from the semantic similarity principle proposed for concrete words, and provide the first piece of evidence in support of this view obtained from healthy participants. The results shed light on the representational structure of abstract and concrete concepts. |
Jon Andoni Duñabeitia; Manuel Perea; Manuel Carreiras Eye movements when reading words with $YMbOL$ and NUM83R5: There is a cost Journal Article In: Visual Cognition, vol. 17, no. 5, pp. 617–631, 2009. @article{Dunabeitia2009, Recent evidence from masked priming experiments has revealed that readers regularize letter-like symbols and letter-like numbers into their corresponding base letters with minimal processing cost. However, one open question is whether the same pattern occurs when these items are presented during normal silent reading. In the present study, we respond to this question in an eye-movement experiment that included sentences with words that had symbols and numbers as letters, as in ‘‘YESTERDAY I SAW THE SECRE74RY WORKING VERY HARD''. Results revealed that there is a greater reading cost associated with letter-by-number replacements than with letter-by-symbol replacements, especially when the replaced letters occur at the beginning of the word. We examine the implications of these findings for models of visual word recognition and reading. |

Ian Cunnings; Harald Clahsen The time-course of morphological constraints: A study of plurals inside derived words Journal Article In: The Mental Lexicon, vol. 3, no. 2, pp. 149–175, 2008. @article{Cunnings2008, The avoidance of regular but not irregular plurals inside compounds (e.g., *rats eater vs. mice eater) has been one of the most widely studied morphological phenomena in the psycholinguistics literature. To examine whether the constraints that are responsible for this contrast have any general significance beyond compounding, we investigated derived word forms containing regular and irregular plurals in two experiments. Experiment 1 was an offline acceptability judgment task, and Experiment 2 measured eye movements during reading derived words containing regular and irregular plurals and uninflected base nouns. The results from both experiments show that the constraint against regular plurals inside compounds generalizes to derived words. We argue that this constraint cannot be reduced to phonological properties, but is instead morphological in nature. The eye-movement data provide detailed information on the time-course of processing derived word forms indicating that early stages of processing are affected by a general constraint that disallows inflected words from feeding derivational processes, and that the more specific constraint against regular plurals comes in at a subsequent later stage of processing. We argue that these results are consistent with stage-based models of language processing. |
Delphine Dahan; Sarah J. Drucker; Rebecca A. Scarborough Talker adaptation in speech perception: Adjusting the signal or the representations? Journal Article In: Cognition, vol. 108, no. 3, pp. 710–718, 2008. @article{Dahan2008, Past research has established that listeners can accommodate a wide range of talkers in understanding language. How this adjustment operates, however, is a matter of debate. Here, listeners were exposed to spoken words from a speaker of an American English dialect in which the vowel /æ/ is raised before /g/, but not before /k/. Results from two experiments showed that listeners' identification of /k/-final words like back (which are unaffected by the dialect) was facilitated by prior exposure to their dialect-affected /g/-final counterparts, e.g., bag. This facilitation occurred because the competition between interpretations, e.g., bag or back, while hearing the initial portion of the input [bæ], was mitigated by the reduced probability for the input to correspond to bag as produced by this talker. Thus, adaptation to an accent is not just a matter of adjusting the speech signal as it is being heard; adaptation involves dynamic adjustment of the representations stored in the lexicon, according to the characteristics of the speaker or the context. |
Denis Drieghe Foveal processing and word skipping during reading Journal Article In: Psychonomic Bulletin & Review, vol. 15, no. 4, pp. 856–860, 2008. @article{Drieghe2008, An eyetracking experiment is reported examining the assumption that a word is skipped during sentence reading because parafoveal processing during preceding fixations has reached an advanced level in recognizing that word. Word n was presented with reduced contrast, with case alternation, or normally. Reingold and Rayner (2006) reported that, in comparison to the normal condition, reduced contrast increased viewing times on word n but not on word n+1, whereas case alternation increased viewing times on both words. These patterns were reflected in the fixation times of the present experiment, but a striking dissociation was observed in the skipping of word n+1: The reduced contrast of word n decreased skipping of word n+1, whereas case alternation did not. Apart from the amount of parafoveal processing, the decision to skip word n+1 is also influenced by the ease of processing word n: Difficulties in processing word n lead to a more conservative strategy in the decision to skip word n+1. |

Results consistently showed that words with a dense associative neighborhood (high-NoA words) were processed faster than words with a sparse neighborhood (low-NoA words), extending previous findings from English lexical decision and categorization experiments. These results are interpreted in terms of the higher degree of semantic richness of high-NoA words as compared with low-NoA words. |
Joana Acha; Manuel Perea The effect of neighborhood frequency in reading: Evidence with transposed-letter neighbors Journal Article In: Cognition, vol. 108, pp. 290–300, 2008. @article{Acha2008, Transposed-letter effects (e.g., jugde activates judge) pose serious models for models of visual-word recognition that use position-specific coding schemes. However, even though the evidence of transposed-letter effects with nonword stimuli is strong, the evidence for word stimuli is scarce and inconclusive. The present experiment examined the effect of neighborhood frequency during normal silent reading using transposed-letter neighbors (e.g., silver, sliver). Two sets of low-frequency words were created (equated in the number of substitution neighbors, word frequency, and number of letters), which were embedded in sentences. In one set, the target word had a higher frequency transposed-letter neighbor, and in the other set, the target word had no transposed-letter neighbors. An inhibitory effect of neighborhood frequency was observed in measures that reflect late processing in words (number of regressions back to the target word, and total time). We examine the implications of these findings for models of visual-word recognition and reading. |

Words n + 1 and n + 2 had either correct or incorrect previews prior to fixation (prior to crossing the boundary location). In addition, the manipulation utilized either a high or low frequency word in word n + 1 location on the assumption that it would be more likely that n + 2 preview effects could be obtained when word n + 1 was high frequency. The primary findings were that there was no evidence for a preview benefit for word n + 2 and no evidence for parafoveal-on-foveal effects when word n + 1 is at least four letters long. We discuss implications for models of eye-movement control in reading. |
Jennifer E. Arnold THE BACON not the bacon: How children and adults understand accented and unaccented noun phrases Journal Article In: Cognition, vol. 108, no. 1, pp. 69–99, 2008. @article{Arnold2008, Two eye-tracking experiments examine whether adults and 4- and 5-year-old children use the presence or absence of accenting to guide their interpretation of noun phrases (e.g., the bacon) with respect to the discourse context. Unaccented nouns tend to refer to contextually accessible referents, while accented variants tend to be used for less accessible entities. Experiment 1 confirms that accenting is informative for adults, who show a bias toward previously-mentioned objects beginning 300 ms after the onset of unaccented nouns and pronouns. But contrary to findings in the literature, accented words produced no observable bias. In Experiment 2, 4 and 5 year olds were also biased toward previously-mentioned objects with unaccented nouns and pronouns. This builds on findings of limits on children's on-line reference comprehension [Arnold, J. E., Brown-Schmidt, S., & Trueswell, J. C. (2007). Children's use of gender and order-of-mention during pronoun comprehension. Language and Cognitive Processes], showing that children's interpretation of unaccented nouns and pronouns is constrained in contexts with one single highly accessible object. |

Lao Put in last position something previously unmentioned: Word order effects on referential expectancy and reference comprehension Journal Article In: Language and Cognitive Processes, vol. 23, no. 2, pp. 282–295, 2008. @article{Arnold2008a, Research has shown that the comprehension of definite referring expressions (e.g., "the triangle") tends to be faster for "given" (previously mentioned) referents, compared with new referents. This has been attributed to the presence of given information in the consciousness of discourse participants (e.g., Chafe, 1994) suggesting that given is always more accessible. By contrast, we find a bias toward new referents during the on-line comprehension of the direct object in heavy-NP-shifted word orders, e.g., "Put on the star the...." This order tends to be used for new direct objects; canonical unshifted orders are more common with given direct objects. Thus, word order provides probabilistic information about the givenness or newness of the direct object. Results from eyetracking and gating experiments show that the traditional given bias only occurs with unshifted orders; with heavy-NP-shifted orders, comprehenders expect the object to be new, and comprehension for new referents is facilitated.

In Experiment 1, sentences had 4 types of spacing: normal unspaced text, text with spaces between words, text with spaces between characters that yielded nonwords, and finally text with spaces between every character. The authors investigated whether the introduction of spaces into unspaced Chinese text facilitates reading and whether the word or, alternatively, the character is a unit of information that is of primary importance in Chinese reading. Global and local measures indicated that sentences with unfamiliar word spaced format were as easy to read as visually familiar unspaced text. Nonword spacing and a space between every character produced longer reading times. In Experiment 2, highlighting was used to create analogous conditions: normal Chinese text, highlighting that marked words, highlighting that yielded nonwords, and highlighting that marked each character. The data from both experiments clearly indicated that words, and not individual characters, are the unit of primary importance in Chinese reading. |

Bohn; Reinhold Kliegl; Ralf Engbert; Jürgen Kurths Reconstruction of eye movements during blinks Journal Article In: Chaos, vol. 18, no. 1, pp. 1–15, 2008. @article{Baptista2008, In eye movement research in reading, the amount of data plays a crucial role for the validation of results. A methodological problem for the analysis of the eye movement in reading are blinks, when readers close their eyes. Blinking rate increases with increasing reading time, resulting in high data losses, especially for older adults or reading impaired subjects. We present a method, based on the symbolic sequence dynamics of the eye movements, that reconstructs the horizontal position of the eyes while the reader blinks. The method makes use of an observed fact that the movements of the eyes before closing or after opening contain information about the eyes movements during blinks. Test results indicate that our reconstruction method is superior to methods that use simpler interpolation approaches. In addition, analyses of the reconstructed data show no significant deviation from the usual behavior observed in readers. |
Dale J. Barr Pragmatic expectations and linguistic evidence: Listeners anticipate but do not integrate common ground Journal Article In: Cognition, vol. 109, no. 1, pp. 18–40, 2008. @article{Barr2008, When listeners search for the referent of a speaker's expression, they experience interference from privileged knowledge, knowledge outside of their 'common ground' with the speaker. Evidence is presented that this interference reflects limitations in lexical processing. In three experiments, listeners' eye movements were monitored as they searched for the target of a speaker's referring expression in a display that also contained a phonological competitor (e.g., bucket/buckle). Listeners anticipated that the speaker would refer to something in common ground, but they did not experience less interference from a competitor in privileged ground than from a matched competitor in common ground. In contrast, interference from the competitor was eliminated when it was ruled out by a semantic constraint. These findings support a view of comprehension as relying on multiple systems with distinct access to information and present a challenge for constraint-based views of common ground. |

Shortly following the target verb onset, listeners looked at the recipient more (relative to the theme) following DO than PO primes, indicating that the structure of the prime affected listeners' eye gazes on the target scene. Crucially, this priming effect was the same irrespective of whether the postverbal nouns in the prime sentences did ("The monarch will send the painting to the president") or did not ("The monarch will send the envoy to the president") differ in animacy, suggesting that PO/DO priming in comprehension occurs because structural properties, rather than animacy features, are being primed when people process the ditransitive target verb. |
Lillian Chen; Julie E. Boland Dominance and context effects on activation of alternative homophone meanings Journal Article In: Memory & Cognition, vol. 36, no. 7, pp. 1306–1323, 2008. @article{Chen2008, Two eyetracking-during-listening experiments showed frequency and context effects on fixation probability for pictures representing multiple meanings of homophones. Participants heard either an imperative sentence instructing them to look at a homophone referent (Experiment 1) or a declarative sentence that was either neutral or biased toward the homophone's subordinate meaning (Experiment 2). At homophone onset in both experiments, the participants viewed four pictures: (1) a referent of one homophone meaning, (2) a shape competitor for a nonpictured homophone meaning, and (3) two unrelated filler objects. In Experiment 1, meaning dominance affected looks to both the homophone referent and the shape competitor. In Experiment 2, as compared with neutral contexts, subordinatebiased contexts lowered the fixation probability for shape competitors of dominant meanings, but shape competitors still attracted more looks than would be expected by chance. We discuss the consistencies and discrepancies of these findings with the selective access and reordered access theories of lexical ambiguity resolution. |

Jacobs Perception of speech reflects optimal use of probabilistic speech cues Journal Article In: Cognition, vol. 108, no. 3, pp. 804–809, 2008. @article{Clayards2008, Listeners are exquisitely sensitive to fine-grained acoustic detail within phonetic categories for sounds and words. Here we show that this sensitivity is optimal given the probabilistic nature of speech cues. We manipulated the probability distribution of one probabilistic cue, voice onset time (VOT), which differentiates word initial labial stops in English (e.g., "beach" and "peach"). Participants categorized words from distributions of VOT with wide or narrow variances. Uncertainty about word identity was measured by four-alternative forced-choice judgments and by the probability of looks to pictures. Both measures closely reflected the posterior probability of the word given the likelihood distributions of VOT, suggesting that listeners are sensitive to these distributions. |
Sarah C. Creel; Richard N. Aslin; Michael K. Tanenhaus Heeding the voice of experience: The role of talker variation in lexical access Journal Article In: Cognition, vol. 106, no. 2, pp. 633–664, 2008. @article{Creel2008, Two experiments used the head-mounted eye-tracking methodology to examine the time course of lexical activation in the face of a non-phonemic cue, talker variation. We found that lexical competition was attenuated by consistent talker differences between words that would otherwise be lexical competitors. In Experiment 1, some English cohort word-pairs were consistently spoken by a single talker (male couch, male cows), while other word-pairs were spoken by different talkers (male sheep, female sheet). After repeated instances of talker-word pairings, words from different-talker pairs showed smaller proportions of competitor fixations than words from same-talker pairs. In Experiment 2, participants learned to identify black-and-white shapes from novel labels spoken by one of two talkers. All of the 16 novel labels were VCVCV word-forms atypical of, but not phonologically illegal in, English. Again, a word was consistently spoken by one talker, and its cohort or rhyme competitor was consistently spoken either by that same talker (same-talker competitor) or the other talker (different-talker competitor). Targets with different-talker cohorts received greater fixation proportions than targets with same-talker cohorts, while the reverse was true for fixations to cohort competitors; there were fewer erroneous selections of competitor referents for different-talker competitors than same-talker competitors. Overall, these results support a view of the lexicon in which entries contain extra-phonemic information. Extensions of the artificial lexicon paradigm and developmental implications are discussed. © 2007 Elsevier B.V. All rights reserved. |
Ralf Engbert; Antje Nuthmann Self-consistent estimation of mislocated fixations during reading Journal Article In: PLoS ONE, vol. 3, no. 2, pp. e1534, 2008. @article{Engbert2008, During reading, we generate saccadic eye movements to move words into the center of the visual field for word processing. However, due to systematic and random errors in the oculomotor system, distributions of within-word landing positions are rather broad and show overlapping tails, which suggests that a fraction of fixations is mislocated and falls on words to the left or right of the selected target word. Here we propose a new procedure for the self-consistent estimation of the likelihood of mislocated fixations in normal reading. Our approach is based on iterative computation of the proportions of several types of oculomotor errors, the underlying probabilities for word-targeting, and corrected distributions of landing positions. We found that the average fraction of mislocated fixations ranges from about 10% to more than 30% depending on word length. These results show that fixation probabilities are strongly affected by oculomotor errors. |
Paola Escudero; Rachel Hayes-Harb; Holger Mitterer Novel second-language words and asymmetric lexical access Journal Article In: Journal of Phonetics, vol. 36, no. 2, pp. 345–360, 2008. @article{Escudero2008, The lexical and phonetic mapping of auditorily confusable L2 nonwords was examined by teaching L2 learners novel words and by later examining their word recognition using an eye-tracking paradigm. During word learning, two groups of highly proficient Dutch learners of English learned 20 English nonwords, of which 10 contained the English contrast /ε/-æ/ (a confusable contrast for native Dutch speakers). One group of subjects learned the words by matching their auditory forms to pictured meanings, while a second group additionally saw the spelled forms of the words. We found that the group who received only auditory forms confused words containing /æ/ and /ε/ symmetrically, i.e., both /æ/ and /ε/ auditory tokens triggered looks to pictures containing both /æ/ and /ε/. In contrast, the group who also had access to spelled forms showed the same asymmetric word recognition pattern found by previous studies, i.e., they only looked at pictures of words containing /ε/ when presented with /ε/ target tokens, but looked at pictures of words containing both /æ/ and /ε/ when presented with /æ/ target tokens. The results demonstrate that L2 learners can form lexical contrasts for auditorily confusable novel L2 words. However, and most importantly, this study suggests that explicit information over the contrastive nature of two new sounds may be needed to build separate lexical representations for similar-sounding L2 words. |
Steven Frisson; Brian McElree Complement coercion is not modulated by competition: Evidence from eye movements Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 1, pp. 1–11, 2008. @article{Frisson2008a, An eye-movement study examined the processing of expressions requiring complement coercion (J. Pustejovsky, 1995), in which a noun phrase that does not denote an event (e.g., the book) appears as the complement of an event-selecting verb (e.g., began the book). Previous studies demonstrated that these expressions are more costly to process than are control expressions that can be processed with basic compositional operations (L. Pylkka ̈nen & B. McElree, 2006). Complement coercion is thought to be costly because comprehenders need to construct an event sense of the complement to satisfy the semantic restrictions of the verb (e.g., began writing the book). The reported experiment tests the alternative hypotheses that the cost arises from the need to select 1 interpretation from several or from competition between alternative interpretations. Expressions with weakly constrained interpretations (no dominant interpretation and several alternative interpretations) were not more costly to process than expressions with a strongly constrained interpretation (1 dominant interpretation and few alternative interpretations). These results are consistent with the hypothesis that the cost reflects the on-line construction of an event sense for the complement. |
Steven Frisson; Elizabeth Niswander-Klement; Alexander Pollatsek The role of semantic transparency in the processing of English compound words Journal Article In: British Journal of Psychology, vol. 99, no. 1, pp. 87–107, 2008. @article{Frisson2008, Experiment 1 examined whether the semantic transparency of an English unspaced compound word affected how long it took to process it in reading. Three types of opaque words were each compared with a matched set of transparent words (i.e. matched on the length and frequency of the constituents and the frequency of the word as a whole). Two sets of the opaque words were partially opaque: either the first constituent was not related to the meaning of the compound (opaque-transparent) or the second constituent was not related to the meaning of the compound (transparent-opaque). In the third set (opaque-opaque), neither constituent was related to the meaning of the compound. For all three sets, there was no significant difference between the opaque and the transparent words on any eye-movement measure. This replicates an earlier finding with Finnish compound words (Pollatsek & Hyönä, 2005) and indicates that, although there is now abundant evidence that the component constituents play a role in the encoding of compound words, the meaning of the compound word is not constructed from the parts, at least for compound words for which a lexical entry exists. Experiment 2 used the same compounds but with a space between the constituents. This presentation resulted in a transparency effect, indicating that when an assembly route is 'forced', transparency does play a role. |

Meyer; Marc Ouellet; Christine Häcker Parallel processing of objects in a naming task Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 4, pp. 982–987, 2008. @article{Meyer2008, The authors investigated whether speakers who named several objects processed them sequentially or in parallel. Speakers named object triplets, arranged in a triangle, in the order left, right, and bottom object. The left object was easy or difficult to identify and name. During the saccade from the left to the right object, the right object shown at trial onset (the interloper) was replaced by a new object (the target), which the speakers named. Interloper and target were identical or unrelated objects, or they were conceptually unrelated objects with the same name (e.g., bat [animal] and [baseball] bat). The mean duration of the gazes to the target was shorter when interloper and target were identical or had the same name than when they were unrelated. The facilitatory effects of identical and homophonous interlopers were significantly larger when the left object was easy to process than when it was difficult to process. This interaction demonstrates that the speakers processed the left and right objects in parallel. |
Don C. Mitchell; Xingjia Shen; Matthew J. Green; Timothy L. Hodgson Accounting for regressive eye-movements in models of sentence processing: A reappraisal of the Selective Reanalysis hypothesis Journal Article In: Journal of Memory and Language, vol. 59, no. 3, pp. 266–293, 2008. @article{Mitchell2008, When people read temporarily ambiguous sentences, there is often an increased prevalence of regressive eye-movements launched from the word that resolves the ambiguity. Traditionally, such regressions have been interpreted at least in part as reflecting readers' efforts to re-read and reconfigure earlier material, as exemplified by the Selective Reanalysis hypothesis [Frazier, L., & Rayner, K. (1982). Making and correcting errors during sentence comprehension: Eye movements in the analysis of structurally ambiguous sentences. Cognitive Psychology, 14, 178-210]. Within such frameworks it is assumed that the selection of saccadic landing-sites is linguistically supervised. As an alternative to this proposal, we consider the possibility (dubbed the Time Out hypothesis) that regression control is partly decoupled from linguistic operations and that landing-sites are instead selected on the basis of low-level spatial properties such as their proximity to the point from which the regressive saccade was launched. Two eye-tracking experiments were conducted to compare the explanatory potential of these two accounts. Experiment 1 manipulated the formatting of linguistically identical sentences and showed, contrary to purely linguistic supervision, that the landing site of the first regression from a critical word was reliably influenced by the physical layout of the text. Experiment 2 used a fixed physical format but manipulated the position in the display at which reanalysis-relevant material was located. Here the results showed a highly reliable linguistic influence on the overall distribution of regression landing sites (though with few effects being apparent on the very first regression). These results are interpreted as reflecting mutually exclusive forms of regression control with fixation sequences being influenced both by spatially constrained, partially decoupled supervision systems as well as by some kind of linguistic guidance. The findings are discussed in relation to existing computational models of eye-movements in reading. |

On most trials, participants named two objects; but on some trials, the objects were replaced shortly after trial onset by a written word probe, which participants had to name instead of the objects. In Experiment 1, the word was presented in the same location as the left object either 150 or 350 msec after trial onset and was either phonologically related or unrelated to that object name. Phonological facilitation was observed at the later but not at the earlier SOA. In Experiment 2, the word was either phonologically related or unrelated to the right object and was presented 150 msec after the speaker had begun to inspect that object. In contrast with Experiment 1, phonological facilitation was found at this early SOA, demonstrating that the speakers had begun to process the right object prior to fixation. |

Tanenhaus Addressees distinguish shared from private information when interpreting questions during interactive conversation Journal Article In: Cognition, vol. 107, no. 3, pp. 1122–1134, 2008. @article{BrownSchmidt2008, Two experiments examined the role of common ground in the production and on-line interpretation of wh-questions such as What's above the cow with shoes? Experiment 1 examined unscripted conversation, and found that speakers consistently use wh-questions to inquire about information known only to the addressee. Addressees were sensitive to this tendency, and quickly directed attention toward private entities when interpreting these questions. A second experiment replicated the interpretation findings in a more constrained setting. These results add to previous evidence that the common ground influences initial language processes, and suggests that the strength and polarity of common ground effects may depend on contributions of sentence type as well as the interactivity of the situation. |

Harris; Liina Pylkkänen; Brian McElree; Steven Frisson The cost of question concealment: Eye-tracking and MEG evidence Journal Article In: Brain and Language, vol. 107, no. 1, pp. 44–61, 2008. @article{Harris2008, Although natural language appears to be largely compositional, the meanings of certain expressions cannot be straightforwardly recovered from the meanings of their parts. This study examined the online processing of one such class of expressions: concealed questions, in which the meaning of a complex noun phrase (the proof of the theorem) shifts to a covert question (what the proof of the theorem is) when mandated by a sub-class of question-selecting verbs (e.g., guess). Previous behavioral and magnetoencephalographic (MEG) studies have reported a cost associated with converting an entity denotation to an event. Our study tested whether both types of meaning-shift affect the same computational resources by examining the effects elicited by concealed questions in eye-tracking and MEG. Experiment 1 found evidence from eye-movements that verbs requiring the concealed question interpretation require more processing time than verbs that do not support a shift in meaning. Experiment 2 localized the cost of the concealed question interpretation in the left posterior temporal region, an area distinct from that affected by complement coercion. Experiment 3 presented the critical verbs in isolation and found no posterior temporal effect, confirming that the effect of Experiment 2 reflected sentential, and not lexical-level, processing. |
Suiping Wang; Hsuan-Chih Chen; Jinmian Yang; Lei Mo Immediacy of integration in discourse comprehension: Evidence from Chinese readers' eye movements Journal Article In: Language and Cognitive Processes, vol. 23, no. 2, pp. 241–257, 2008. @article{Wang2008a, An eye-movement study was conducted to examine whether Chinese readers immediately activate and integrate related background information during discourse comprehension. Participants were asked to read short passages, each containing a critical word that fitted well within the local context but was inconsistent or neutral with background information from the early part of the passage. This manipulation of textual consistency produced reliable effects on both first-pass reading fixations in the target region and second-pass reading times in the pre-target and target regions. These results indicate that integration processes start very rapidly in reading text in a writing system with properties that encourage delayed processing, suggesting that immediate processing is likely a universal principle in discourse comprehension. |
Tessa Warren; Kerry McConnell; Keith Rayner Effects of context on eye movements when reading about possible and impossible events Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 4, pp. 1001–1010, 2008. @article{Warren2008, Plausibility violations resulting in impossible scenarios lead to earlier and longer lasting eye movement disruption than violations resulting in highly unlikely scenarios (K. Rayner, T. Warren, B. J. Juhasz, & S. P. Liversedge, 2004; T. Warren & K. McConnell, 2007). This could reflect either differences in the timing of availability of different kinds of information (e.g., selectional restrictions, world knowledge, and context) or differences in their relative power to guide semantic interpretation. The authors investigated eye movements to possible and impossible events in real-world and fantasy contexts to determine when contextual information influences detection of impossibility cued by a semantic mismatch between a verb and an argument. Gaze durations on a target word were longer to impossible events independent of context. However, a measure of the time elapsed from first fixating the target word to moving past it showed disruption only in the real-world context. These results suggest that contextual information did not eliminate initial disruption but moderated it quickly thereafter. |
Sarah J. White; Raymond Bertram; Jukka Hyönä Semantic processing of previews within compound words Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 4, pp. 988–993, 2008. @article{White2008a, Previous studies have suggested that previews of words prior to fixation can be processed orthographically, but not semantically, during reading of sentences (K. Rayner, D. A. Balota, & A. Pollatsek, 1986). The present study tested whether semantic processing of previews can occur within words. The preview of the second constituent of 2-constituent Finnish compound nouns was manipulated. The previews were either identical to the 2nd constituent or they were incorrect in the form of a semantically related word, a semantically unrelated word, or a semantically meaningless nonword. The results indicate that previews of 2nd constituents within compound words can be semantically processed. The results have important implications for understanding the nature of preview and compound word processing. These issues are crucial to developing comprehensive models of eye-movement control and word recognition during reading. |
Seppo Vainio; Jukka Hyönä; Anneli Pajunen Processing modifier-head agreement in reading: Evidence for a delayed effect of agreement Journal Article In: Memory & Cognition, vol. 36, no. 2, pp. 329–340, 2008. @article{Vainio2008, The present study examined whether type of inflectional case (semantic or grammatical) and phonological and morphological transparency affect the processing of Finnish modifier-head agreement in reading. Readers' eye movement patterns were registered. In Experiment 1, an agreeing modifier condition (agreement was transparent) was compared with a no-modifier condition, and in Experiment 2, similar constructions with opaque agreement were used. In both experiments, agreement was found to affect the processing of the target noun with some delay. In Experiment 3, unmarked and case-marked modifiers were used. The results again demonstrated a delayed agreement effect, ruling out the possibility that the agreement effects observed in Experiments 1 and 2 reflect a mere modifier-presence effect. We concluded that agreement exerts its effect at the level of syntactic integration but not at the level of lexical access. |

For language learners, however, formulaic patterns are a major barrier to achieving native like compe- tence. The present study investigated the processing of lexical bundles by native speakers and less advanced non-native English speakers using corpus analysis for the identification of lexical bundles and eye-tracking to measure the reading times. The participants read sentences containing 4-grams and control phrases which were matched for sub-string fre- quency. The results for native speakers demonstrate a processing advantage for formulaic sequences over the matched control units. We do not find any processing advantage for non-native speakers which suggests that native like processing of lexical bundles comes only late in the acquisition process |

Tanenhaus Acquiring and processing verb argument structure: Distributional learning in a miniature language Journal Article In: Cognitive Psychology, vol. 56, no. 3, pp. 165–209, 2008. @article{Wonnacott2008, Adult knowledge of a language involves correctly balancing lexically-based and more language-general patterns. For example, verb argument structures may sometimes readily generalize to new verbs, yet with particular verbs may resist generalization. From the perspective of acquisition, this creates significant learnability problems, with some researchers claiming a crucial role for verb semantics in the determination of when generalization may and may not occur. Similarly, there has been debate regarding how verb-specific and more generalized constraints interact in sentence processing and on the role of semantics in this process. The current work explores these issues using artificial language learning. In three experiments using languages without semantic cues to verb distribution, we demonstrate that learners can acquire both verb-specific and verb-general patterns, based on distributional information in the linguistic input regarding each of the verbs as well as across the language as a whole. As with natural languages, these factors are shown to affect production, judgments and real-time processing. We demonstrate that learners apply a rational procedure in determining their usage of these different input statistics and conclude by suggesting that a Bayesian perspective on statistical learning may be an appropriate framework for capturing our findings. |
Mark Yates; John Friend; Danielle M. Ploetz The effect of phonological neighborhood density on eye movements during reading Journal Article In: Cognition, vol. 107, no. 2, pp. 685–692, 2008. @article{Yates2008, Recent research has indicated that phonological neighbors speed processing in a variety of isolated word recognition tasks. Nevertheless, as these tasks do not represent how we normally read, it is not clear if phonological neighborhood has an effect on the reading of sentences for meaning. In the research reported here, we evaluated whether phonological neighborhood density influences reading of target words embedded in sentences. The eye movement data clearly revealed that phonological neighborhood facilitated reading. This was evidenced by shorter fixations for words with large neighborhoods relative to words with small neighborhoods. These results are important in indicating that phonology is a crucial component of reading and that it affects early lexical processing. © 2007 Elsevier B.V. All rights reserved. |

Sedivy Lexical-semantic activation in Broca's and Wernicke's aphasia: Evidence from eye movements Journal Article In: Journal of Cognitive Neuroscience, vol. 20, no. 4, pp. 592–612, 2008. @article{Yee2008, Lexical processing requires both activating stored representations, and selecting among active candidates. The current work uses an eye-tracking paradigm to conduct a detailed temporal investigation of lexical processing. Patients with Broca's and Wernicke's aphasia are studied to shed light on the roles of anterior and posterior brain regions in lexical processing as well as the effects of lexical competition on such processing. Experiment 1 investigates whether objects semantically related to an uttered word are preferentially fixated, e.g., given the auditory target 'hammer', do participants fixate a picture of a nail? Results show that, like normals, both groups of patients are more likely to fixate on an object semantically related to the target than an unrelated object. Experiment 2 explores whether Broca's and Wernicke's aphasics show competition effects when words share onsets with the uttered word, e.g., given the auditory target 'hammer', do participants fixate a picture of a hammock? Experiment 3 investigates whether these patients activate words semantically related to onset competitors of the uttered word, e.g., given the auditory target 'hammock' do participants fixate a nail due to partial activation of the onset competitor hammer? Results of Experiments 2 and 3 show pathological patterns of performance for both Broca's and Wernicke's aphasics under conditions of lexical onset competition. However, the patterns of deficit differed, suggesting different functional and computational roles for anterior and posterior areas in lexical processing. Implications of the findings for the functional architecture of the lexical processing system and its potential neural substrates are considered. |

Hung Eye movements and parafoveal word processing in reading Chinese Journal Article In: Memory & Cognition, vol. 36, no. 5, pp. 1033–1045, 2008. @article{Yen2008, In two experiments, a parafoveal lexicality effect in the reading of Chinese (a script that does not physically mark word boundaries) was examined. Both experiments used the boundary paradigm (Rayner, 1975) and indicated that the lexical properties of parafoveal words influenced eye movements. In Experiment 1, the preview stimulus was either a real word or a pseudoword. Targets with word previews, even unrelated ones, were more likely to be skipped than were those with pseudowords. In Experiment 2, all of the preview stimuli had the same first character as the target. Target words with same-morpheme previews were fixated for less time than were those with pseudoword previews, suggesting that morphological processing may be involved in extracting information from parafoveal words in Chinese reading. Together, the two experiments dealing with how words are processed in Chinese may provide some constraints on current computational models of reading. |

Reilly The role of global top-down factors in local eye-movement control in reading Journal Article In: Psychological Research, vol. 72, no. 6, pp. 675–688, 2008. @article{Radach2008, Although the development of the field of reading has been impressive, there are a number of issues that still require much more attention. One of these concerns the variability of skilled reading within the individual. This paper explores the topic in three ways: (1) it quantifies the extent to which, two factors, the specific reading task (comprehension vs. word verification) and the format of reading material (sentence vs. passage) influence the temporal aspects of reading as expressed in word-viewing durations; (2) it examines whether they also affect visuomotor aspects of eye-movement control; and (3) determine whether they can modulate local lexical processing. The results reveal reading as a dynamic, interactive process involving semi-autonomous modules, with top-down influences clearly evident in the eye-movement record. |

Aslin Context and spoken word recognition in a novel lexicon Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 5, pp. 1207–1223, 2008. @article{Revill2008, Three eye movement studies with novel lexicons investigated the role of semantic context in spoken word recognition, contrasting 3 models: restrictive access, access–selection, and continuous integration. Actions directed at novel shapes caused changes in motion (e.g., looming, spinning) or state (e.g., color, texture). Across the experiments, novel names for the actions and the shapes varied in frequency, cohort density, and whether the cohorts referred to actions (Experiment 1) or shapes with action-congruent or action-incongruent affordances (Experiments 2 and 3). Experiment 1 demonstrated effects of frequency and cohort competition from both displayed and non-displayed competitors. In Experiment 2, a biasing context induced an increase in anticipatory eye movements to congruent referents and reduced the probability of looks to incongruent cohorts, without the delay predicted by access–selection models. In Experiment 3, context did not reduce competition from non-displayed incompatible neighbors as predicted by restrictive access models. The authors conclude that the results are most consistent with continuous integration models. |
Leah Roberts; Marianne Gullberg; Peter Indefrey Online pronoun resolution in L2 discouse: L1 influence and general learner effects Journal Article In: Studies in Second Language Acquisition, vol. 30, pp. 333–357, 2008. @article{Roberts2008, This study investigates whether advanced second language (L2) learners of a nonnull subject language (Dutch) are influenced by their null subject first language (L1) (Turkish) in their offline and online resolution of subject pronouns in L2 discourse. To tease apart potential L1 effects from possible general L2 processing effects, we also tested a group of German L2 learners of Dutch who were predicted to perform like the native Dutch speakers. The two L2 groups differed in their offline interpretations of subject pronouns. The Turkish L2 learners exhibited a L1 influence, because approximately half the time they interpreted Dutch subject pronouns as they would overt pronouns in Turkish, whereas the German L2 learners performed like the Dutch controls, interpreting pronouns as coreferential with the current discourse topic. This L1 effect was not in evidence in eye-tracking data, however. Instead, the L2 learners patterned together, showing an online processing disadvantage when two potential antecedents for the pronoun were grammatically available in the discourse. This processing disadvantage was in evidence irrespective of the properties of the learners' L1 or their final interpretation of the pronoun. Therefore, the results of this study indicate both an effect of the L1 on the L2 in offline resolution and a general L2 processing effect in online subject pronoun resolution. |
Ardi Roelofs Attention, gaze shifting, and dual-task interference from phonological encoding in spoken word planning Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 34, no. 6, pp. 1580–1598, 2008. @article{Roelofs2008, Controversy exists about whether dual-task interference from word planning reflects structural bottleneck or attentional control factors. Here, participants named pictures whose names could or could not be phonologically prepared, and they manually responded to arrows presented away from (Experiment 1), or superimposed onto, the pictures (Experiments 2 and 3); or they responded to tones (Experiment 4). Pictures and arrows/tones were presented at stimulus onset asynchronies of 0, 300, and 1,000 ms. Earlier research showed that vocal responding hampers auditory perception, which predicts earlier shifts of attention to the tones than to the arrows. Word planning yielded dual-task interference. Phonological preparation reduced the latencies of picture naming and gaze shifting. The preparation benefit was propagated into the latencies of the manual responses to the arrows but not to the tones. The malleability of the interference supports the attentional control account. This conclusion was corroborated by computer simulations showing that an extension of WEAVER++ (A. Roelofs, 2003) with assumptions about the attentional control of tasks quantitatively accounts for the latencies of vocal responding, gaze shifting, and manual responding. |
Ardi Roelofs Tracing attention and the activation flow in spoken word planning using eye movements Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 34, no. 2, pp. 353–368, 2008. @article{Roelofs2008a, The flow of activation from concepts to phonological forms within the word production system was examined in 3 experiments. In Experiment 1, participants named pictures while ignoring superimposed distractor pictures that were semantically related, phonologically related, or unrelated. Eye movements and naming latencies were recorded. The distractor pictures affected the latencies of gaze shifting and vocal naming. The magnitude of the phonological effects increased linearly with latency, excluding lapses of attention as the cause of the effects. In Experiment 2, no distractor effects were obtained when both pictures were named. When pictures with superimposed distractor words were named or the words were read in Experiment 3, the words influenced the latencies of gaze shifting and picture naming, but the pictures yielded no such latency effects in word reading. The picture-word asymmetry was obtained even with equivalent reading and naming latencies. The picture-picture effects suggest that activation spreads continuously from concepts to phonological forms, whereas the picture-word asymmetry indicates that the amount of activation is limited and task dependent. |
Christoph Scheepers; Frank Keller; Mirella Lapata Evidence for serial coercion: A time course analysis using the visual-world paradigm Journal Article In: Cognitive Psychology, vol. 56, no. 1, pp. 1–29, 2008. @article{Scheepers2008, Metonymic verbs like start or enjoy often occur with artifact-denoting complements (e.g., The artist started the picture) although semantically they require event-denoting complements (e.g., The artist started painting the picture). In case of artifact-denoting objects, the complement is assumed to be type shifted (or coerced) into an event to conform to the verb's semantic restrictions. Psycholinguistic research has provided evidence for this kind of enriched composition: readers experience processing difficulty when faced with metonymic constructions compared to non-metonymic controls. However, slower reading times for metonymic constructions could also be due to competition between multiple interpretations that are being entertained in parallel whenever a metonymic verb is encountered. Using the visual-world paradigm, we devised an experiment which enabled us to determine the time course of metonymic interpretation in relation to non-metonymic controls. The experiment provided evidence in favor of a non-competitive, serial coercion process. |

Using multiple regression analysis, our main result shows that two significant predictors, number of saccades per sentence followed by average fixation duration, account for 94% of reading speed variance: reading speed decreases when number of saccades and fixation duration increase. The number of letters per forward saccade (L/FS), which was measured directly in contrast to previous studies, is not a significant predictor. The results suggest that, independently of the size of saccades, some or all portions of a sentence are temporally integrated across an increasing number of fixations as reading speed is reduced. |

A region to the right of fixation lead to best reading performance and most natural gaze behavior, whereas reading performance was severely impaired when a region to the left or below fixation had to be used. An analysis of the underlying oculomotor behavior revealed that practice effects were accompanied by a larger number of saccades in text direction and decreased fixation durations, whereas no adjustment of saccade amplitudes was observed. We provide an explanation for the observed performance differences at different retinal locations based on the interplay of attention and eye movements. Our findings have important implications for the development of training methods for MD patients targeted at reading, suggesting that it would be beneficial for MD patients to use a region to the right of their central scotoma. |

Aslin Immediate effects of form-class constraints on spoken word recognition Journal Article In: Cognition, vol. 108, no. 3, pp. 866–873, 2008. @article{Magnuson2008, In many domains of cognitive processing there is strong support for bottom-up priority and delayed top-down (contextual) integration. We ask whether this applies to supra-lexical context that could potentially constrain lexical access. Previous findings of early context integration in word recognition have typically used constraints that can be linked to pair-wise conceptual relations between words. Using an artificial lexicon, we found immediate integration of syntactic expectations based on pragmatic constraints linked to syntactic categories rather than words: phonologically similar "nouns" and "adjectives" did not compete when a combination of syntactic and visual information strongly predicted form class. These results suggest that predictive context is integrated continuously, and that previous findings supporting delayed context integration stem from weak contexts rather than delayed integration. |
Andrea E. Martin; Brian McElree A content-addressable pointer mechanism underlies comprehension of verb-phrase ellipsis Journal Article In: Journal of Memory and Language, vol. 58, no. 3, pp. 879–906, 2008. @article{Martin2008, Interpreting a verb-phrase ellipsis (VP ellipsis) requires accessing an antecedent in memory, and then integrating a representation of this antecedent into the local context. We investigated the online interpretation of VP ellipsis in an eye-tracking experiment and four speed-accuracy tradeoff experiments. To investigate whether the antecedent for a VP ellipsis is accessed with a search or direct-access retrieval process, Experiments 1 and 2 measured the effect of the distance between an ellipsis and its antecedent on the speed and accuracy of comprehension. Accuracy was lower with longer distances, indicating that interpolated material reduced the quality of retrieved information about the antecedent. However, contra a search process, distance did not affect the speed of interpreting ellipsis. This pattern suggests that antecedent representations are content-addressable and retrieved with a direct-access process. To determine whether interpreting ellipsis involves copying antecedent information into the ellipsis site, Experiments 3-5 manipulated the length and complexity of the antecedent. Some types of antecedent complexity lowered accuracy, notably, the number of discourse entities in the antecedent. However, neither antecedent length nor complexity affected the speed of interpreting the ellipsis. This pattern is inconsistent with a copy operation, and it suggests that ellipsis interpretation may involve a pointer to extant structures in memory. |

Experiment 1 demonstrated gradient effects along voice-onset time (VOT) continua made from natural speech, replicating results with synthetic speech (B. McMurray, M. K. Tanenhaus, & R. N. Aslin, 2002). Experiments 2-5 used synthetic VOT continua to examine effects of response alternatives (2 vs. 4), task (lexical vs. phoneme decision), and type of token (word vs. consonant-vowel). A gradient effect of VOT in at least one half of the continuum was observed in all conditions. These results suggest that during online spoken word recognition, lexical competitors are activated in proportion to their continuous distance from a category boundary. This gradient processing may allow listeners to anticipate upcoming acoustic-phonetic information in the speech signal and dynamically compensate for acoustic variability. |

Aslin Tracking the time course of phonetic cue integration during spoken word recognition Journal Article In: Psychonomic Bulletin & Review, vol. 15, no. 6, pp. 1064–1071, 2008. @article{McMurray2008a, Speech perception requires listeners to integrate multiple cues that each contribute to judgments about a phonetic category. Classic studies of trading relations assessed the weights attached to each cue but did not explore the time course of cue integration. Here, we provide the first direct evidence that asynchronous cues to voicing (/b/ vs. /p/) and manner (/b/ vs. /w/) contrasts become available to the listener at different times during spoken word recognition. Using the visual world paradigm, we show that the probability of eye movements to pictures of target and of competitor objects diverge at different points in time after the onset of the target word. These points of divergence correspond to the availability of early (voice onset time or formant transition slope) and late (vowel length) cues to voicing and manner contrasts. These results support a model of cue integration in which phonetic cues are used for lexical access as soon as they are available. |

The use of novel prefixed words allows one to examine the roles of whole-word access and decompositional processing in the processing of non-novel prefixed words. The two experiments found that, although there was a large cost to novelty (e.g., gaze durations were about 100 ms longer for novel prefixedwords), the effect of the frequency of the root morpheme on fixation measures was about the same for novel and non-novel prefixed words for most measures. This finding rules out a (‘‘horse-race'') dual-route model of processing for existing prefixed words in which the whole-word and decompositional route are parallel and independent, as such a model would predict a substantially larger root frequency effect for novel words (where whole-word processes do not exist). The most likely model to explain the processing of prefixed words is a parallel interactive one. |

Harald Baayen Morphological dynamics in compound processing Journal Article In: Language and Cognitive Processes, vol. 23, no. 7-8, pp. 1089–1132, 2008. @article{Kuperman2008, This paper explores the time-course of morphological processing of trimorphemic Finnish compounds. We find evidence for the parallel access to full- forms and morphological constituents diagnosed by the early effects of compound frequency, as well as early effects of left constituent frequency and family size. We also observe an interaction between compound frequency and both the left and the right constituent family sizes. Furthermore, our data show that suffixes embedded in the derived left constituent of a compound are efficiently used for establishing the boundary between compounds' constituents. The success of segmentation of a compound is demonstrably modulated by the affixal salience of the embedded suffixes. We discuss implications of these findings for current models of morphological processing and propose a new model that views morphemes, combinations of morphemes and morphological paradigms as probabilistic sources of information that are interactively used in recognition of complex words. |

Researchers disagree as to whether these delays are caused by impaired phonological processing or whether extra-phonological processes also play a role (e.g., Clarke, P., Hulme, C., & Snowling, M.

Naming-speed processes, timing, and reading: A conceptual review. Journal of learning disabilities, 33(4), 387-407). We conducted an eye-tracking study that manipulated phonological and visual information (as representative of extra-phonological processes) in RAN. Results from linear mixed (LME) effects analyses showed that both phonological and visual processes influence naming-speed for both dyslexic and non-dyslexic groups, but the influence on dyslexic readers is greater. Moreover, dyslexic readers' difficulties in these domains primarily emerge in a measure that explicitly includes the production phase of naming. This study elucidates processes underpinning RAN performance in non-dyslexic readers and pinpoints areas of difficulty for dyslexic readers. We discuss these findings with reference to phonological and extra-phonological hypotheses of naming-speed deficits. |
Johanna K. Kaakinen; Jukka Hyönä Perspective-driven text comprehension Journal Article In: Applied Cognitive Psychology, vol. 22, pp. 319–334, 2008. @article{Kaakinen2008, The present article reports results of an eye‐tracking experiment, which examines whether the perspective‐driven text comprehension framework applies to comprehension of narrative text. Sixty‐four participants were instructed to adopt either a burglar's or an interior designer's perspective. A pilot test showed that readers have more overlapping prior knowledge with the burglar‐relevant than with the interior designer‐relevant information of the experimental text. Participants read either a transparent text version where the (ir)relevance of text segments to the perspective was made apparent, or an opaque text version where no direct mention of the perspective was made. After reading participants wrote a free recall of the text. The results showed that perspective‐related prior knowledge modulates the perspective effects observed in on‐line text processing and that signalling of (ir)relevance helps in encoding relevant information to memory. It is concluded that the proposed framework generalizes to the on‐line comprehension of narrative texts. |

Hartsuiker When you name the pizza you look at the coin and the bread: Eye movements reveal semantic activation during word production Journal Article In: Memory & Cognition, vol. 36, no. 2, pp. 341–360, 2008. @article{Huettig2008, Two eyetracking experiments tested for activation of category coordinate and perceptually related concepts when speakers prepare the name of an object. Speakers saw four visual objects in a 2 x 2 array and identified and named a target picture on the basis of either category (e.g., "What is the name of the musical instrument?") or visual-form (e.g., "What is the name of the circular object?") instructions. There were more fixations on visual-form competitors and category coordinate competitors than on unrelated objects during name preparation, but the increased overt attention did not affect naming latencies. The data demonstrate that eye movements are a sensitive measure of the overlap between the conceptual (including visual-form) information that is accessed in preparation for word production and the conceptual knowledge associated with visual objects. Furthermore, these results suggest that semantic activation of competitor concepts does not necessarily affect lexical selection, contrary to the predictions of lexical-selection-by-competition accounts (e.g., Levelt, Roelofs, & Meyer, 1999). |
Albrecht W. Inhoff; Matthew S. Solomon; Bradley A. Seymour; Ralph Radach Eye position changes during reading fixations are spatially selective Journal Article In: Vision Research, vol. 48, no. 8, pp. 1027–1039, 2008. @article{Inhoff2008, Intra-fixation location changes were measured when one-line sentences written in lower or aLtErNaTiNg case were read. Intra-fixation location changes were common and their size was normally distributed except for a relatively high proportion of fixations without a discernible location change. Location changes that did occur were systematically biased toward the right when alternating case was read. Irrespective of case type, changes of the right eye were biased toward the right at the onset of sentence reading, and this spatial bias decreased as sentence reading progressed from left to right. The left eye showed a relatively stable right-directed bias. These results show that processing demands can pull the two fixated eyes in the same direction and that the response to this pull can differ for the right and left eye. |

Three tasks were used–lexical decision, naming, and sentence reading–all of which focused on the effects of lexeme frequency as a function of lexeme dominance. The results revealed a larger word frequency effect for the dominant lexeme in all three tasks. Eye movements during sentence reading further revealed larger word frequency effects for the dominant lexeme via several oculomotor motor measures, including the duration of the first fixation on a compound word. These findings favor theoretical conceptions in which the use of lexeme meaning is an integral part of the compound recognition process. |

Falk Huettig; Gerry T. M. Altmann Visual-shape competition during language-mediated attention is based on lexical input and not modulated by contextual appropriateness Journal Article In: Visual Cognition, vol. 15, no. 8, pp. 985–1018, 2007. @article{Huettig2007, Visual attention can be directed immediately, as a spoken word unfolds, towards conceptually related but nonassociated objects, even if they mismatch on other dimensions that would normally determine which objects in the scene were appropriate referents for the unfolding word (Huettig & Altmann, 2005). Here we demonstrate that the mapping between language and concurrent visual objects can also be mediated by visual-shape relations. On hearing "snake", participants directed overt attention immediately, within a visual display depicting four objects, to a picture of an electric cable, although participants had viewed the visual display with four objects for approximately 5 s before hearing the target word-sufficient time to recognize the objects for what they were. The time spent fixating the cable correlated significantly with ratings of the visual similarity between snakes in general and this particular cable. Importantly, with sentences contextually biased towards the concept snake, participants looked at the snake well before the onset of "snake'', but they did not look at the visually similar cable until hearing "snake''. Finally, we demonstrate that such activation can, under certain circumstances (e. g., during the processing of dominant meanings of homonyms), constrain the direction of visual attention even when it is clearly contextually inappropriate. We conclude that language-mediated attention can be guided by a visual match between spoken words and visual objects, but that such a match is based on lexical input and may not be modulated by contextual appropriateness. |
Falk Huettig; James M. McQueen The tug of war between phonological, semantic and shape information in language-mediated visual search Journal Article In: Journal of Memory and Language, vol. 57, no. 4, pp. 460–482, 2007. @article{Huettig2007a, Experiments 1 and 2 examined the time-course of retrieval of phonological, visual-shape and semantic knowledge as Dutch participants listened to sentences and looked at displays of four pictures. Given a sentence with beker, 'beaker', for example, the display contained phonological (a beaver, bever), shape (a bobbin, klos), and semantic (a fork, vork) competitors. When the display appeared at sentence onset, fixations to phonological competitors preceded fixations to shape and semantic competitors. When display onset was 200 ms before (e.g.) beker, fixations were directed to shape and then semantic competitors, but not phonological competitors. In Experiments 3 and 4, displays contained the printed names of the previously-pictured entities; only phonological competitors were fixated preferentially. These findings suggest that retrieval of phonological, shape and semantic knowledge in the spoken-word and picture-recognition systems is cascaded, and that visual attention shifts are co-determined by the time-course of retrieval of all three knowledge types and by the nature of the information in the visual environment. |
Lisa Irmen What's in a (role) name? Formal and conceptual aspects of comprehending personal nouns Journal Article In: Journal of Psycholinguistic Research, vol. 36, no. 6, pp. 431–456, 2007. @article{Irmen2007, Two eye-tracking studies assessed effects of grammatical and conceptual gender cues in generic role name processing in German. Participants read passages about a social or occupational group introduced by way of a generic role name (e.g., Soldaten/soldiers, Künstler/artists). Later in the passage the gender of this group was specified by the anaphoric expression diese Männer/these men or diese Frauen/these women. Testing masculine generic role names of male, female or neutral conceptual gender (Exp. 1) showed that a gender mismatch between the role name's conceptual gender and the anaphor significantly slowed reading immediately before and after the anaphoric noun. A mismatch between the antecedent's grammatical gender and the anaphor slowed down the reading of the anaphoric noun itself. Testing grammatically gender-unmarked role names (Exp. 2) revealed a general male bias in participants' understanding, irrespective of grammatical or conceptual gender. The experiments extend previous findings on gender effects to non-referential role names and generic contexts. Theoretical aspects of gender and plural reference as well as gender information in mental models are discussed. |

Aslin The dynamics of lexical competition during spoken word recognition Journal Article In: Cognitive Science, vol. 31, no. 1, pp. 133–156, 2007. @article{Magnuson2007, The sounds that make up spoken words are heard in a series and must be mapped rapidly onto words in memory because their elements, unlike those of visual words, cannot simultaneously exist or persist in time. Although theories agree that the dynamics of spoken word recognition are important, they differ in how they treat the nature of the competitor set-precisely which words are activated as an auditory word form unfolds in real time. This study used eye tracking to measure the impact over time of word frequency and 2 partially overlapping competitor set definitions: onset density and neighborhood density. Time course measures revealed early and continuous effects of frequency (facilitatory) and on set based similarity (inhibitory). Neighborhood density appears to have early facilitatory effects and late inhibitory effects. The late inhibitory effects are due to differences in the temporal distribution of similarity within neighborhoods. The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine-grained goodness-of-fit and competition dynamics. |
Ardi Roelofs Attention and gaze control in picture naming, word reading, and word categorizing Journal Article In: Journal of Memory and Language, vol. 57, no. 2, pp. 232–251, 2007. @article{Roelofs2007, The trigger for shifting gaze between stimuli requiring vocal and manual responses was examined. Participants were presented with picture-word stimuli and left- or right-pointing arrows. They vocally named the picture (Experiment 1), read the word (Experiment 2), or categorized the word (Experiment 3) and shifted their gaze to the arrow to manually indicate its direction. The experiments showed that the temporal coordination of vocal responding and gaze shifting depends on the vocal task and, to a lesser extent, on the type of relationship between picture and word. There was a close temporal link between gaze shifting and manual responding, suggesting that the gaze shifts indexed shifts of attention between the vocal and manual tasks. Computer simulations showed that a simple extension of WEAVER++ [Roelofs, A. (1992). A spreading-activation theory of lemma retrieval in speaking. Cognition, 42, 107-142.; Roelofs, A. (2003). Goal-referenced selection of verbal action: modeling attentional control in the Stroop task.

Lawrence Eye movements as direct tests of the GO model for the missing-letter effect Journal Article In: Perception and Psychophysics, vol. 69, no. 3, pp. 324–337, 2007. @article{RoyCharland2007a, When asked to detect target letters while reading a text, participants miss more letters in frequently occurring function words than in less frequent content words. To account for this pattern of results, known as the missing-letter effect, Greenberg, Healy, Koriat, and Kreiner proposed the guidance-organization (GO) model, which integrates the two leading models of the missing-letter effect while incorporating innovative assumptions based on the literature on eye movements during reading. The GO model was evaluated by monitoring the eye movements of participants while they searched for a target letter in a continuous text display. Results revealed the usual missing-letter effect, and many empirical benchmark effects in eye movement literature were observed. However, contrary to the predictions of the GO model, response latencies were longer for function words than for content words. Alternative models are discussed that can accommodate both error and response latency data for the missing-letter effect. |
Miia Sainio; Jukka Hyönä; Kazuo Bingushi; Raymond Bertram The role of interword spacing in reading Japanese: An eye movement study Journal Article In: Vision Research, vol. 47, no. 20, pp. 2575–2584, 2007. @article{Sainio2007, The present study investigated the role of interword spacing in a naturally unspaced language, Japanese. Eye movements were registered of native Japanese readers reading pure Hiragana (syllabic) and mixed Kanji-Hiragana (ideographic and syllabic) text in spaced and unspaced conditions. Interword spacing facilitated both word identification and eye guidance when reading syllabic script, but not when the script contained ideographic characters. We conclude that in reading Hiragana interword spacing serves as an effective segmentation cue. In contrast, spacing information in mixed Kanji-Hiragana text is redundant, since the visually salient Kanji characters serve as effective segmentation cues by themselves. |

Hartsuiker; Dirk Speelman Dutch collective nouns and conceptual profiling Journal Article In: Linguistics, vol. 45, no. 1, pp. 85–132, 2007. @article{Joosten2007, Collective nouns such as committee, family, or team are conceptually (and in English also syntactically) complex in the sense that they are both singular ("one") and plural ("more than one"): they refer to a multiplicity that is conceptualized as a unity. In this article, which focuses on Dutch collective nouns, it is argued that some collective nouns are rather "one", whereas others are rather "more than one". Collective nouns are shown to be different from one another in member level accessibility. Whereas all collective nouns have both a conceptual collection level ("one") and a conceptual member level ("more than one"), the latter is not always conceptually profiled (i.e., focused on) to the same extent. A gradient is sketched in which collective nouns such as bemanning ('crew') (member level highly accessible) and vereniging ('association') (member level scarcely accessible) form the extremes. Arguments in favor of the conceptual phenomenon of variable member level accessibility derive from an analysis of property distribution, from corpus research on verbal and pronominal singular-plural variation, and from a psycholinguistic eye-tracking experiment. |
Johanna K. Kaakinen; Jukka Hyönä Strategy use in the reading span test: An analysis of eye movements and reported encoding strategies Journal Article In: Memory, vol. 15, no. 6, pp. 634–646, 2007. @article{Kaakinen2007, Strategy use in the traditional reading span test was examined by recording participants' eye movements during the task (Experiment 1) and by interviewing participants about their strategy use (Experiment 2). In Experiment 1, no differences between individuals with a low, medium, and high span were observed in how they distributed processing time between task elements. In all three groups, fixation times on words up to the to-be-remembered (TBR) word became shorter and the time spent on the TBR longer as memory load in the task increased. The results of Experiment 2, however, show that span groups differ in the use of memory encoding strategies: individuals with a low span use mainly rehearsal, whereas individuals with a high span use almost exclusively semantic elaboration. The results indicate that the use of elaborative strategies may enhance span performance but that not all individuals are necessarily able to use such strategies efficiently. |
Johanna K. Kaakinen; Jukka Hyönä Perspective effects in repeated reading: An eye movement study Journal Article In: Memory & Cognition, vol. 35, no. 6, pp. 1323–1336, 2007. @article{Kaakinen2007a, The present study examined the influence of perspective instructions on online processing of expository text during repeated reading. Sixty-two participants read either a high or a low prior knowledge (HPK vs. LPK) text twice from a given perspective while their eye movements were recorded. They switched perspective before a third reading. Reading perspective affected the first-pass reading and also increased sentence wrap-up processing time in the perspective-relevant sentences. Prior knowledge facilitated the recognition of the (ir)relevance of text information and resulted in relatively earlier perspective effects in the HPK versus LPK text. Repeated reading facilitated processing, as indicated by all eye movement measures. After the perspective switch, a repetition benefit was observed for the previously relevant text information, whereas a repetition cost was found for the previously irrelevant text information. These results indicate that reading perspective and prior knowledge have a significant influence on how readers allocate visual attention during reading. |

There was no preview benefit for 1st-pass reading on word n + 2, replicating the results of K. Rayner, B. J. Juhasz, and S. J. Brown (2007), but there was a preview benefit on the 3-letter word n + 1, that is, after the boundary but before word n + 2. Additionally, both word n + 1 and word n + 2 exhibited parafoveal-on-foveal effects on word n. Thus, during a fixation on word n and given a short word n + 1, some information is extracted from word n + 2, supporting the hypothesis of distributed processing in the perceptual span. |
Pia Knoeferle; Matthew W. Crocker The influence of recent scene events on spoken comprehension: Evidence from eye movements Journal Article In: Journal of Memory and Language, vol. 57, no. 4, pp. 519–543, 2007. @article{Knoeferle2007, Evidence from recent experiments that monitored attention in clipart scenes during spoken comprehension suggests that people preferably rely on non-stereotypical depicted events over stereotypical thematic knowledge for incremental interpretation. The Coordinated Interplay Account [Knoeferle, P., & Crocker, M. W. (2006). The coordinated interplay of scene, utterance, and world knowledge: evidence from eye tracking. Cognitive Science, 30, 481-529.] accounts for this preference through referential processing (e.g., the verb mediates a depicted event) and the preferred use of scene event information that is associated with the referent (e.g., the agent of the depicted event). Three eye-tracking experiments examined the generality of this account. While the rapid use of depicted events was replicated in all three studies, the preference to rely on them was modulated by the decay of events that were no longer co-present. Our findings motivate the extension of the Coordinated Interplay Account with an explicit working memory. The coordinated interplay mechanism together with working memory and decay, is shown to account for the influence of scene-derived versus stored knowledge both when events are co-present and when they have recently been perceived. |
James M. McQueen; Malte C. Viebahn Tracking recognition of spoken words by tracking looks to printed words Journal Article In: Quarterly Journal of Experimental Psychology, vol. 60, no. 5, pp. 661–671, 2007. @article{McQueen2007, Eye movements of Dutch participants were tracked as they looked at arrays of four words on a computer screen and followed spoken instructions (e.g., "Klik op het woord buffel": Click on the word buffalo). The arrays included the target (e.g., buffel), a phonological competitor (e.g., buffer, buffer), and two unrelated distractors. Targets were monosyllabic or bisyllabic, and competitors mismatched targets only on either their onset or offset phoneme and only by one distinctive feature. Participants looked at competitors more than at distractors, but this effect was much stronger for offset-mismatch than onset-mismatch competitors. Fixations to competitors started to decrease as soon as phonetic evidence disfavouring those competitors could influence behaviour. These results confirm that listeners continuously update their interpretation of words as the evidence in the speech signal unfolds and hence establish the viability of the methodology of using eye movements to arrays of printed words to track spoken-word recognition. |

Swaab Coreference and lexical repetition: Mechanisms of discourse integration Journal Article In: Memory & Cognition, vol. 35, no. 4, pp. 801–815, 2007. @article{Ledoux2007, The use of repeated expressions to establish coreference allows an investigation of the relationship between basic processes of word recognition and higher level language processes that involve the integration of information into a discourse model. In two experiments on reading, we used eye tracking and event-related potentials to examine whether repeated expressions that are coreferential within a local discourse context show the kind of repetition priming that is shown in lists of words. In both experiments, the effects of lexical repetition were modulated by the effects of local discourse context that arose from manipulations of the linguistic prominence of the antecedent of a coreferentially repeated name. These results are interpreted within the context of discourse prominence theory, which suggests that processes of coreferential interpretation interact with basic mechanisms of memory integration during the construction of a model of discourse. |
Yoonhyoung Lee; Hanjung Lee; Peter C. Gordon Linguistic complexity and information structure in Korean: Evidence from eye-tracking during reading Journal Article In: Cognition, vol. 104, no. 3, pp. 495–534, 2007. @article{Lee2007, The nature of the memory processes that support language comprehension and the manner in which information packaging influences online sentence processing were investigated in three experiments that used eye-tracking during reading to measure the ease of understanding complex sentences in Korean. All three experiments examined reading of embedded complement sentences; the third experiment additionally examined reading of sentences with object-modifying, object-extracted relative clauses. In Korean, both of these structures place two NPs with nominative case marking early in the sentence, with the embedded and matrix verbs following later. The type (pronoun, name or description) of these two critical NPs was varied in the experiments. When the initial NPs were of the same type, comprehension was slowed after participants had read the sentence-final verbs, a finding that supports the view that working memory in language comprehension is constrained by similarity-based interference during the retrieval of information necessary to determine the syntactic or semantic relations between noun phrases and verb phrases. Ease of comprehension was also influenced by the association between type of NP and syntactic position, with the best performance being observed when more definite NPs (pronouns and names) were in a prominent syntactic position (e.g., matrix subject) and less definite NPs (descriptions) were in a non-prominent syntactic position (embedded subject). This pattern provides evidence that the interpretation of sentences is facilitated by consistent packaging of information in different linguistic elements. |

The role of H*L, L*H and deaccentuation was also examined in diphonesynthetic speech. It was found that H*L and L*HL create a strong bias towards newness, whereas L*H, like deaccentuation, creates a strong bias towards givenness. In synthetic speech, the same effect was found for H*L, L*H and deaccentuation, but it was delayed. The delay may not be caused entirely by the difference in the segmental quality between synthetic and natural speech. The pitch accent H*LH, however, appears to bias participants' interpretation to the target word, independent of its information status. This finding was explained in the light of the effect of durational information at the segmental level on word recognition. © Walter de Gruyter 2007. |

Readers are skimming instead of reading in depth [Nielson 1997]. Highlights are increasingly used in digital interfaces to direct attention toward relevant passages within texts. In this paper, we study the eye-gaze behavior of subjects using both keyword highlighting and ScentHighlights [Chi et al. 2005]. In this first eye-tracking study of highlighting interfaces, we show that there is direct evidence of the von Restorff isolation effect [VonRestorff 1933] in the eye-tracking data, in that subjects focused on highlighted areas when highlighting cues are present. The results point to future design possibilities in highlighting interfaces. |
Ian Cunnings; Harald Clahsen The time-course of morphological constraints: Evidence from eye-movements during reading Journal Article In: Cognition, vol. 104, no. 3, pp. 476–494, 2007. @article{Cunnings2007, Lexical compounds in English are constrained in that the non-head noun can be an irregular but not a regular plural (e.g. mice eater vs. *rats eater), a contrast that has been argued to derive from a morphological constraint on modifiers inside compounds. In addition, bare nouns are preferred over plural forms inside compounds (e.g. mouse eater vs. mice eater), a contrast that has been ascribed to the semantics of compounds. Measuring eye-movements during reading, this study examined how morphological and semantic information become available over time during the processing of a compound. We found that the morphological constraint affected both early and late eye-movement measures, whereas the semantic constraint for singular non-heads only affected late measures of processing. These results indicate that morphological information becomes available earlier than semantic information during the processing of compounds. |
