Manuel Perea; Chie Nakatani; Cees Leeuwen Transposition effects in reading Japanese Kana: Are they orthographic in nature? Journal Article In: Memory & Cognition, vol. 39, no. 4, pp. 700–707, 2011. @article{Perea2011, One critical question for the front end of models of visual-word recognition and reading is whether the stage of letter position coding is purely orthographic or whether phonology is (to some degree) involved. To explore this issue, we conducted a silent reading experiment in Japanese Kana–a script in which orthography and phonology can be easily separated–using a technique that is highly sensitive to phonological effects (i.e., Rayner's (1975) boundary technique). Results showed shorter fixation times on the target word when the parafoveal preview was a transposed-mora nonword (a.ri.me.ka [アリメカ]-a.me.ri.ka [アメリカ]) than when the preview was a replacement-mora nonword (a.ka.ho.ka [アカホカ] -a.me.ri.ka [アメリカ]). More critically, fixation times on the target word were remarkably similar when the parafoveal preview was a transposed-consonant nonword (a.re.mi.ka [アレミカ]-a.ri.me.ka [アリメカ]) and when the parafoveal preview was an orthographic control nonword (a.ke.hi.ka [アケヒカ]-a.me.ri.ka [アメリカ]). Thus, these findings offer strong support for the view that letter/mora position coding during silent reading is orthographic in nature. |
Alexander Pollatsek; Raymond Bertram; Jukka Hyönä Processing novel and lexicalised Finnish compound words Journal Article In: Journal of Cognitive Psychology, vol. 23, no. 7, pp. 795–810, 2011. @article{Pollatsek2011, Participants read sentences in which novel and lexicalized two-constituent compound words appeared while their eye movements were measured. The frequency of the first constituent of the compounds was also varied factorially and the frequency of the lexicalized compounds was equated over the two conditions. The sentence frames prior to the target word were matched across conditions. Both lexicality and first constituent frequency had large and significant effects on gaze durations on the target word; moreover the constituent frequency effect was significantly larger for the novel words. These results indicate that first constituent frequency has an effect in two stages: in the initial encoding of the compound and in the construction of meaning for the novel compound. The difference between this pattern of results and those for English prefixed words (Pollatsek, Slattery, & Juhasz, 2008) is apparently due to differences in the construction of meaning stage. A general model of the relationship of the processing of polymorphemic words to how they are fixated is presented. |
Keith Rayner; Timothy J. Slattery; Denis Drieghe; Simon P. Liversedge Eye movements and word skipping during reading: Effects of word length and predictability Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 37, no. 2, pp. 514–528, 2011. @article{Rayner2011, Eye movements were monitored as subjects read sentences containing high- or low-predictable target words. The extent to which target words were predictable from prior context was varied: Half of the target words were predictable, and the other half were unpredictable. In addition, the length of the target word varied: The target words were short (4–6 letters), medium (7–9 letters), or long (10–12 letters). Length and predictability both yielded strong effects on the probability of skipping the target words and on the amount of time readers fixated the target words (when they were not skipped). However, there was no interaction in any of the measures examined for either skipping or fixation time. The results demonstrate that word predictability (due to contextual constraint) and word length have strong and independent influences on word skipping and fixation durations. Furthermore, because the long words extended beyond the word identification span, the data indicate that skipping can occur on the basis of partial information in relation to word identity. |
Eva Reinisch; Alexandra Jesse; James M. McQueen Speaking rate from proximal and distal contexts is used during word segmentation Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 37, no. 3, pp. 978–996, 2011. @article{Reinisch2011, A series of eye-tracking and categorization experiments investigated the use of speaking-rate information in the segmentation of Dutch ambiguous-word sequences. Juncture phonemes with ambiguous durations (e.g., [s] in 'eens (s)peer,' "once (s)pear," [t] in 'nooit (t)rap,' "never staircase/quick") were perceived as longer and hence more often as word-initial when following a fast than a slow context sentence. Listeners used speaking-rate information as soon as it became available. Rate information from a context proximal to the juncture phoneme and from a more distal context was used during on-line word recognition, as reflected in listeners' eye movements. Stronger effects of distal context, however, were observed in the categorization task, which measures the off-line results of the word-recognition process. In categorization, the amount of rate context had the greatest influence on the use of rate information, but in eye tracking, the rate information's proximal location was the most important. These findings constrain accounts of how speaking rate modulates the interpretation of durational cues during word recognition by suggesting that rate estimates are used to evaluate upcoming phonetic information continuously during prelexical speech processing. |
Ardi Roelofs Attention, exposure duration, and gaze shifting in naming performance Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 37, no. 3, pp. 860–873, 2011. @article{Roelofs2011, Two experiments are reported in which the role of attribute exposure duration in naming performance was examined by tracking eye movements. Participants were presented with color-word Stroop stimuli and left- or right-pointing arrows on different sides of a computer screen. They named the color attribute and shifted their gaze to the arrow to manually indicate its direction. The color attribute (Experiment 1) or the complete color-word stimulus (Experiment 2) was removed from the screen 100 ms after stimulus onset. Compared with presentation until trial offset, removing the color attribute diminished Stroop interference, as well as facilitation effects in color naming latencies, whereas removing the complete stimulus diminished interference only. Attribute and stimulus removal reduced the latency of gaze shifting, which suggests decreased rather than increased attentional demand. These results provide evidence that limiting exposure duration contributes to attribute naming performance by diminishing the extent to which irrelevant attributes are processed, which reduces attentional demand. |
Anne Pier Salverda; Gerry T. M. Altmann Attentional capture of objects referred to by spoken language Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 37, no. 4, pp. 1122–1133, 2011. @article{Salverda2011, Participants saw a small number of objects in a visual display and performed a visual detection or visual-discrimination task in the context of task-irrelevant spoken distractors. In each experiment, a visual cue was presented 400 ms after the onset of a spoken word. In experiments 1 and 2, the cue was an isoluminant color change and participants generated an eye movement to the target object. In experiment 1, responses were slower when the spoken word referred to the distractor object than when it referred to the target object. In experiment 2, responses were slower when the spoken word referred to a distractor object than when it referred to an object not in the display. In experiment 3, the cue was a small shift in location of the target object and participants indicated the direction of the shift. Responses were slowest when the word referred to the distractor object, faster when the word did not have a referent, and fastest when the word referred to the target object. Taken together, the results demonstrate that referents of spoken words capture attention. |
Hua Shu; Wei Zhou; Ming Yan; Reinhold Kliegl Font size modulates saccade-target selection in chinese reading Journal Article In: Attention, Perception, and Psychophysics, vol. 73, no. 2, pp. 482–490, 2011. @article{Shu2011, In alphabetic writing systems, saccade amplitude (a close correlate of reading speed) is independent of font size, presumably because an increase in the angular size of letters is compensated for by a decrease of visual acuity with eccentricity. We propose that this invariance may (also) be due to the presence of spaces between words, guiding the eyes across a large range of font sizes. Here, we test whether saccade amplitude is also invariant against manipulations of font size during reading Chinese, a character-based writing system without spaces as explicit word boundaries for saccade-target selection. In contrast to word-spaced alphabetic writing systems, saccade amplitude decreased significantly with increased font size, leading to an increase in the number of fixations at the beginning of words and in the number of refixations. These results are consistent with a model which assumes that word beginning (rather than word center) is the default saccade target if the length of the parafoveal word is not available. |
Anna Siyanova-Chanturia; Kathy Conklin; Norbert Schmitt Adding more fuel to the fire: An eye-tracking study of idiom processing by native and non-native speakers Journal Article In: Second Language Research, vol. 27, no. 2, pp. 251–272, 2011. @article{SiyanovaChanturia2011, Using eye-tracking, we investigate on-line processing of idioms in a biasing story context by native and non-native speakers of English. The stimuli are idioms used figuratively ("at the end of the day"–"eventually"), literally ("at the end of the day"–"in the evening"), and novel phrases ("at the end of the war"). Native speaker results indicate a processing advantage for idioms over novel phrases, as evidenced by fewer and shorter fixations. Further, no processing advantage is found for figurative idiom uses over literal ones in a full idiom analysis or in a recognition point analysis. Contrary to native speaker results, non-native findings suggest that L2 speakers process idioms at a similar speed to novel phrases. Further, figurative uses are processed more slowly than literal ones. Importantly, the recognition point analysis allows us to establish where non-natives slow down when processing the figurative meaning. |
Anna Siyanova-Chanturia; Kathy Conklin; Walter J. B. Heuven Seeing a phrase "time and again" matters: The role of phrasal frequency in the processing of multiword sequences Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 37, no. 3, pp. 776–784, 2011. @article{SiyanovaChanturia2011a, Are speakers sensitive to the frequency with which phrases occur in language? The authors report an eye-tracking study that investigates this by examining the processing of multiword sequences that differ in phrasal frequency by native and proficient nonnative English speakers. Participants read sentences containing 3-word binomial phrases (bride and groom) and their reversed forms (groom and bride), which are identical in syntax and meaning but that differ in phrasal frequency. Mixed-effects modeling revealed that native speakers and nonnative speakers, across a range of proficiencies, are sensitive to the frequency with which phrases occur in English. Results also indicate that native speakers and higher proficiency nonnatives are sensitive to whether a phrase occurs in a particular configuration (binomial vs. reversed) in English, highlighting the contribution of entrenchment of a particular phrase in memory. |
Timothy J. Slattery; Bernhard Angele; Keith Rayner Eye movements and display change detection during reading Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 37, no. 6, pp. 1924–1938, 2011. @article{Slattery2011, In the boundary change paradigm (Rayner, 1975), when a reader's eyes cross an invisible boundary location, a preview word is replaced by a target word. Readers are generally unaware of such changes due to saccadic suppression. However, some readers detect changes on a few trials and a small percentage of them detect many changes. Two experiments are reported in which we combined eye movement data with signal detection analyses to investigate display change detection. On each trial, readers had to indicate if they saw a display change in addition to reading for meaning. On half the trials the display change occurred during the saccade (immediate condition); on the other half, it was slowed by 15-25 ms (delay condition) to increase the likelihood that a change would be detected. Sentences were presented in an alternating case fashion allowing us to investigate the influence of both letter identity and case. In the immediate condition, change detection was higher when letters changed than when case changed corroborating findings that word processing utilizes abstract (case independent) letter identities. However, in the delay condition (where d' was much higher than the immediate condition), detection was equal for letter and case changes. The results of both experiments indicate that sensitivity to display changes was related to how close the eyes were to the invalid preview on the fixation prior to the display change, as well as the timing of the completion of this change relative to the start of the post-change fixation. |
Timothy J. Slattery; Elizabeth R. Schotter; Raymond W. Berry; Keith Rayner Parafoveal and foveal processing of abbreviations during eye fixations in reading: Making a case for case Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 37, no. 4, pp. 1022–1031, 2011. @article{Slattery2011a, The processing of abbreviations in reading was examined with an eye movement experiment. Abbreviations were of 2 distinct types: acronyms (abbreviations that can be read with the normal grapheme-phoneme correspondence [GPC] rules, such as NASA) and initialisms (abbreviations in which the GPCs are letter names, such as NCAA). Parafoveal and foveal processing of these abbreviations was assessed with the use of the boundary change paradigm (K. Rayner, 1975). Using this paradigm, previews of the abbreviations were either identical to the abbreviation (NASA or NCAA), orthographically legal (NUSO or NOBA), or illegal (NRSB or NRBA). The abbreviations were presented as capital letter strings within normal, predominantly lowercase sentences and also sentences in all capital letters such that the abbreviations would not be visually distinct. The results indicate that acronyms and initialisms undergo different processing during reading and that readers can modulate their processing based on low-level visual cues (distinct capitalization) in parafoveal vision. In particular, readers may be biased to process capitalized letter strings as initialisms in parafoveal vision when the rest of the sentence is normal, lowercase letters. |

Daniel J. Schad; Antje Nuthmann; Ralf Engbert Eye movements during reading of randomly shuffled text Journal Article In: Vision Research, vol. 50, no. 23, pp. 2600–2616, 2010. @article{Schad2010, In research on eye-movement control during reading, the importance of cognitive processes related to language comprehension relative to visuomotor aspects of saccade generation is the topic of an ongoing debate. Here we investigate various eye-movement measures during reading of randomly shuffled meaningless text as compared to normal meaningful text. To ensure processing of the material, readers were occasionally probed for words occurring in normal or shuffled text. For reading of shuffled text we observed longer fixation times, less word skippings, and more refixations than in normal reading. Shuffled-text reading further differed from normal reading in that low-frequency words were not overall fixated longer than high-frequency words. However, the frequency effect was present on long words, but was reversed for short words. Also, consistent with our prior research we found distinct experimental effects of spatially distributed processing over several words at a time, indicating how lexical word processing affected eye movements. Based on analyses of statistical linear mixed-effect models we argue that the results are compatible with the hypothesis that the perceptual span is more strongly modulated by foveal load in the shuffled reading task than in normal reading. Results are discussed in the context of computational models of reading. |
Kerstin I. Schattka; Ralph Radach; Walter Huber Eye movement correlates of acquired central dyslexia Journal Article In: Neuropsychologia, vol. 48, no. 10, pp. 2959–2973, 2010. @article{Schattka2010, Based on recent progress in theory and measurement techniques, the analysis of eye movements has become one of the major methodological tools in experimental reading research. Our work uses this approach to advance the understanding of impaired information processing in acquired central dyslexia of stroke patients with aphasia. Up to now there has been no research attempting to analyze both word-based viewing time measures and local fixation patterns in dyslexic readers. The goal of the study was to find out whether specific eye movement parameters reflect pathologically preferred segmental reading in contrast to lexical reading.We compared oral reading of single words of normal controls (n=11) with six aphasic participants (two cases of deep, surface and residual dyslexia each). Participants were asked to read aloud lines of target words differing in length and frequency. Segmental reading was characterized by deviant spatial distribution of saccadic landing positions with initial fixations located mainly at the beginning of the word, while lexical readers showed the normative 'preferred landing positions' left to the center of the words. Contrary to expectation, word length did not distinguish between segmental and lexical readers, while word frequency showed the expected effect for lexical readers only. Their mean fixation duration was already prolonged during first pass reading reflecting their attempts of immediate access to lexical information. After first pass reading, re-reading time was significantly increased in all participants with acquired central dyslexia due to their exceedingly higher monitoring demands for oral reading. |
Adrian Staub Eye movements and processing difficulty in object relative clauses Journal Article In: Cognition, vol. 116, no. 1, pp. 71–86, 2010. @article{Staub2010, It is well known that sentences containing object-extracted relative clauses (e.g., The reporter that the senator attacked admitted the error) are more difficult to comprehend than sentences containing subject-extracted relative clauses (e.g., The reporter that attacked the senator admitted the error). Two major accounts of this phenomenon make different predictions about where, in the course of incremental processing of an object relative, difficulty should first appear. An account emphasizing memory processes (Gibson, 1998; Grodner & Gibson, 2005) predicts difficulty at the relative clause verb, while an account emphasizing experience-based expectations (Hale, 2001; Levy, 2008) predicts earlier difficulty, at the relative clause subject. Two eye movement experiments tested these predictions. Regressive saccades were much more likely from the subject noun phrase of an object relative than from the same noun phrase occurring within a subject relative (Experiment 1) or within a verbal complement clause (Experiment 2). This effect was further amplified when the relative pronoun that was omitted. However, reading time was also inflated on the object relative clause verb in both experiments. These results suggest that the violation of expectations and the difficulty of memory retrieval both contribute to the difficulty of object relative clauses, but that these two sources of difficulty have qualitatively distinct behavioral consequences in normal reading. |
Johanna K. Kaakinen; Jukka Hyönä Task effects on eye movements during reading Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 36, no. 6, pp. 1561–1566, 2010. @article{Kaakinen2010, The present study examined how proofreading and reading-for-comprehension instructions influence eye movements during reading. Thirty-seven participants silently read sentences containing compound words as target words while their eye movements were being recorded. We manipulated word length and frequency to examine how task instructions influence orthographic versus lexical-semantic processing during reading. Task instructions influenced both temporal and spatial aspects of eye movements: The initial landing position in words was shifted leftward, the saccade length was shorter, first fixation and gaze duration were longer, and refixation probability was higher during proofreading than during reading for comprehension. Moreover, in comparison to instructions for reading for comprehension, proofreading instructions increased both orthographic and lexical-semantic processing. This became apparent in a greater word length and word frequency effect in gaze duration during proofreading than during reading for comprehension. The present study suggests that the allocation of attentional resources during reading is significantly modulated by task demands. |
Debra Malpass; Antje S. Meyer The time course of name retrieval during multiple-object naming: Evidence from extrafoveal-on-foveal effects Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 36, no. 2, pp. 523–537, 2010. @article{Malpass2010, The goal of the study was to examine whether speakers naming pairs of objects would retrieve the names of the objects in parallel or in sequence. To this end, we recorded the speakers' eye movements and determined whether the difficulty of retrieving the name of the 2nd object affected the duration of the gazes to the 1st object. Two experiments, which differed in the spatial arrangement of the objects, showed that the speakers looked longer at the 1st object when the name of the 2nd object was easy than when it was more difficult to retrieve. Thus, the easy 2nd-object names interfered more with the processing of the 1st object than the more difficult 2nd-object names. In the 3rd experiment, the processing of the 1st object was rendered more difficult by presenting it upside down. No effect of 2nd-object difficulty on the gaze duration for the 1st object was found. These results suggest that speakers can retrieve the names of a foveated and an extrafoveal object in parallel, provided that the processing of the foveated object is not too demanding. |
André Krügel; Ralf Engbert On the launch-site effect for skipped words during reading Journal Article In: Vision Research, vol. 50, no. 16, pp. 1532–1539, 2010. @article{Kruegel2010, The launch-site effect, a systematic variation of within-word landing position as a function of launch-site distance, is among the most important oculomotor phenomena in reading. Here we show that the launch-site effect is strongly modulated in word skipping, a finding which is inconsistent with the view that the launch-site effect is caused by a saccadic-range error. We observe that distributions of landing positions in skipping saccades show an increased leftward shift compared to non-skipping saccades at equal launch-site distances. Using an improved algorithm for the estimation of mislocated fixations, we demonstrate the reliability of our results. |
Victor Kuperman; Michael Dambacher; Antje Nuthmann; Reinhold Kliegl The effect of word position on eye-movements in sentence and paragraph reading Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 9, pp. 1838–1857, 2010. @article{Kuperman2010a, The present study explores the role of the word position-in-text in sentence and paragraph reading. Three eye-movement data sets based on the reading of Dutch and German unrelated sentences reveal a sizeable, replicable increase in reading times over several words at the beginning and the end of sentences. The data from the paragraph-based English-language Dundee corpus replicate the pattern and also indicate that the increase in inspection times is driven by the visual boundaries of the text organized in lines, rather than by syntactic sentence boundaries. We argue that this effect is independent of several established lexical, contextual, and oculomotor predictors of eye-movement behaviour. We also provide evidence that the effect of word position-in-text has two independent components: a start-up effect, arguably caused by a strategic oculomotor programme of saccade planning over the line of text, and a wrap-up effect, originating in cognitive processes of comprehension and semantic integration. |
Pirita Pyykkönen; Jukka Hyönä; Roger P. G. Van Gompel Activating gender stereotypes during online spoken language processing: Evidence from visual world eye tracking Journal Article In: Experimental Psychology, vol. 57, no. 2, pp. 126–133, 2010. @article{Pyykkoenen2010a, This study used the visual world eye-tracking method to investigate activation of general world knowledge related to gender-stereotypical role names in online spoken language comprehension in Finnish. The results showed that listeners activated gender stereotypes elaboratively in story contexts where this information was not needed to build coherence. Furthermore, listeners made additional inferences based on gender stereotypes to revise an already established coherence relation. Both results are consistent with mental models theory (e.g., Garnham, 2001). They are harder to explain by the minimalist account (McKoon & Ratcliff, 1992) which suggests that people limit inferences to those needed to establish coherence in discourse. |
Pirita Pyykkönen; Juhani Jarvikivi Activation and persistence of implicit causality information in spoken language comprehension Journal Article In: Experimental Psychology, vol. 57, no. 1, pp. 5–16, 2010. @article{Pyykkoenen2010, A visual world eye-tracking study investigated the activation and persistence of implicit causality information in spoken language comprehension. We showed that people infer the implicit causality of verbs as soon as they encounter such verbs in discourse, as is predicted by proponents of the immediate focusing account (Greene & McKoon, 1995; Koornneef & Van Berkum, 2006; Van Berkum, Koornneef, Otten, & Nieuwland, 2007). Interestingly, we observed activation of implicit causality information even before people encountered the causal conjunction. However, while implicit causality information was persistent as the discourse unfolded, it did not have a privileged role as a focusing cue immediately at the ambiguous pronoun when people were resolving its antecedent. Instead, our study indicated that implicit causality does not affect all referents to the same extent, rather it interacts with other cues in the discourse, especially when one of the referents is already prominently in focus. |
Keith Rayner; Monica S. Castelhano; Jinmian Yang Preview benefit during eye fixations in reading for older and younger readers Journal Article In: Psychology and Aging, vol. 25, no. 3, pp. 714–718, 2010. @article{Rayner2010, Older and younger readers read sentences as their eye movements were recorded, and the boundary paradigm (Rayner, 1975) was used to present either a valid or an invalid parafoveal preview of a target word. During the saccade to the target word, the preview word changed to the target word. For early measures of processing time (first fixation duration and single fixation duration), the standard preview benefit effect (shorter fixation times on the target word with a valid preview than an invalid preview) was obtained for both older and younger readers. However, for gaze duration and go-past time, the preview benefit was somewhat attenuated in the older readers in comparison to the younger readers, suggesting that on some fixations older readers obtain less preview benefit from the word to the right of fixation. |
Keith Rayner; Timothy J. Slattery; Nathalie N. Bélanger Eye movements, the perceptual span, and reading speed Journal Article In: Psychonomic Bulletin & Review, vol. 17, no. 6, pp. 834–839, 2010. @article{Rayner2010a, The perceptual span or region of effective vision during eye fixations in reading was examined as a function of reading speed (fast readers were compared with slow readers), font characteristics (fixed width vs. proportional width), and intraword spacing (normal or reduced). The main findings were that fast readers (reading at about 330 wpm) had a larger perceptual span than did slow readers (reading about 200 wpm) and that the span was not affected by whether or not the text was fixed width or proportional width. In addition, there were interesting font and intraword spacing effects that have important implications for the optimal use of space in a line of text. |
Erik D. Reichle; Andrew E. Reineberg; Jonathan W. Schooler Eye movements during mindless reading Journal Article In: Psychological Science, vol. 21, no. 9, pp. 1300–1310, 2010. @article{Reichle2010, Mindless reading occurs when the eyes continue moving across the page even though the mind is thinking about something unrelated to the text. Despite how commonly it occurs, very little is known about mindless reading. The present experiment examined eye movements during mindless reading. Comparisons of fixation-duration measures collected during intervals of normal reading and intervals of mindless reading indicate that fixations during the latter were longer and less affected by lexical and linguistic variables than fixations during the former. Also, eye movements immediately preceding self-caught mind wandering were especially erratic. These results suggest that the cognitive processes that guide eye movements during normal reading are not engaged during mindless reading. We discuss the implications of these findings for theories of eye movement control in reading, for the distinction between experiential awareness and meta-awareness, and for reading comprehension. |
Eyal M. Reingold; Jinmian Yang; Keith Rayner The time course of word frequency and case alternation effects on fixation times in reading: Evidence for lexical control of eye movements Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 36, no. 6, pp. 1677–1683, 2010. @article{Reingold2010, Participants' eye movements were monitored while they read sentences in which high-frequency and low-frequency target words were presented either in normal font (e.g., account) or case alternated (e.g., aCcOuNt). The influence of the word frequency and case alternation manipulations on fixation times was examined. Although both manipulations had comparable effects on standard first-pass fixation measures, word frequency, but not case alternation was found to influence the duration of the first fixation in trials with multiple first-pass fixations. Assuming that lexical processing is more often incomplete at the termination of the first in multiple first-pass fixations than at the end of single first-pass fixations, the present findings provide strong evidence for an influence of word frequency on early lexical processing. Importantly, such a demonstration of a fast acting influence of a lexical variable on fixation times satisfies a critical prerequisite for establishing lexical control of eye movements in reading. |
Eva Reinisch; Alexandra Jesse; James M. McQueen Early use of phonetic information in spoken word recognition: Lexical stress drives eye movements immediately Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 4, pp. 772–783, 2010. @article{Reinisch2010, For optimal word recognition listeners should use all relevant acoustic information as soon as it comes available. Using printed-word eye tracking we investigated when during word processing Dutch listeners use suprasegmental lexical stress information to recognize words. Fixations on targets such as "OCtopus" (capitals indicate stress) were more frequent than fixations on segmentally overlapping but differently stressed competitors ("okTOber") before segmental information could disambiguate the words. Furthermore, prior to segmental disambiguation, initially stressed words were stronger lexical competitors than noninitially stressed words. Listeners recognize words by immediately using all relevant information in the speech signal. |
Gui Qin Ren; Yufang Yang Syntactic boundaries and comma placement during silent reading of Chinese text: Evidence from eye movements Journal Article In: Journal of Research in Reading, vol. 33, no. 2, pp. 168–177, 2010. @article{Ren2010, In an eye-tracking experiment, we investigated whether and how a comma influences the reading of Chinese sentences comprised of different types of syntactic constituent such as word, phrase and clause. Participants read Chinese sentences that did or did not insert a comma at the end of a syntactic constituent. The results showed that the fixation times were shorter for the target word followed by a comma than for that followed by no comma, which suggests that a comma facilitated word identification during the reading of Chinese sentences. Furthermore, the insertion of commas shortened the total fixation times in the post-target region only for the clause condition. The data are consistent with previous findings concerning the role of segmentation cues in reading, and compatible with the implicit prosody hypothesis. |
Jean Saint-Aubin The long range parafoveal processing ofsyntactic information is impossible: A reply to Foucambert (2008) Journal Article In: Psychologie Francaise, vol. 55, no. 3, pp. 211–222, 2010. @article{SaintAubin2010, Based on results with a new method, Foucambert (2008) argued that syntactic processing can occur as far as 27 characters to the right of the fixation point. In this reply, we demonstrate that the method used by Foucambert was not appropriate. In addition, Foucambert's results did not support his conclusion. We replicate Foucambert's study while monitoring eye movements. Results revealed that subjects' eye movements were biased to the right of the fixation point. In addition, subjects were unable to engage in syntactic processing of words far in periphery. Taken together, results fit well with current models of eye movements and of the missing-letter effect. |
Jean Saint-Aubin; Sophie Kenny; Annie Roy-Charland The role of eye movements in the missing-letter effect revisited with the rapid serial visual presentation procedure Journal Article In: Canadian Journal of Experimental Psychology, vol. 64, no. 1, pp. 47–52, 2010. @article{SaintAubin2010a, When participants read a text while searching for a target letter, they are more likely to miss the target letter embedded in frequent function words than in less frequent content words. This effect is usually observed with a text displayed normally, for which it has been found that frequent function words are fixated for a smaller amount of time than less frequent content words. However, similar pattern of omissions have been observed with a rapid serial visual presentation procedure in which words appear one at a time. These parallel results would demonstrate that fixation duration per se is not the proximal cause of the missing-letter effect only if eye movements are not made during the rapid serial visual presentation procedure. Therefore, the authors performed eye monitoring during the rapid serial visual presentation procedure. Results revealed that, with a rapid serial visual presentation procedure, participants fixated function and content words for almost the entire presentation duration. It is concluded that eye movements are not the proximal cause of the missing-letter effect. |
Anne Pier Salverda; Michael K. Tanenhaus Tracking the time course of orthographic information in spoken-word recognition Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 36, no. 5, pp. 1108–1117, 2010. @article{Salverda2010, Two visual-world experiments evaluated the time course and use of orthographic information in spoken-word recognition using printed words as referents. Participants saw 4 words on a computer screen and listened to spoken sentences instructing them to click on one of the words (e.g., Click on the word bead). The printed words appeared 200 ms before the onset of the spoken target word. In Experiment 1, the display included the target word and a competitor with either a lower degree (e.g., bear) or a higher degree (e.g., bean) of phonological overlap with the target. Both competitors had the same degree of orthographic overlap with the target. There were more fixations to the competitors than to unrelated distractors. Crucially, the likelihood of fixating a competitor did not vary as a function of the amount of phonological overlap between target and competitor. In Experiment 2, the display included the target word and a competitor with either a lower degree (e.g., bare) or a higher degree (e.g., bear) of orthographic overlap with the target. Competitors were homophonous and thus had the same degree of phonological overlap with the target. There were more fixations to higher overlap competitors than to lower overlap competitors, beginning during the temporal interval where initial fixations driven by the vowel are expected to occur. The authors conclude that orthographic information is rapidly activated as a spoken word unfolds and is immediately used in mapping spoken words onto potential printed referents. |
Sven Hohenstein; Jochen Laubrock; Reinhold Kliegl Semantic preview benefit in eye movements during reading: A parafoveal fast-priming study Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 36, no. 5, pp. 1150–1170, 2010. @article{Hohenstein2010, Eye movements in reading are sensitive to foveal and parafoveal word features. Whereas the influence of orthographic or phonological parafoveal information on gaze control is undisputed, there has been no reliable evidence for early parafoveal extraction of semantic information in alphabetic script. Using a novel combination of the gaze-contingent fast-priming and boundary paradigms, we demonstrate semantic preview benefit when a semantically related parafoveal word was available during the initial 125 ms of a fixation on the pretarget word (Experiments 1 and 2). When the target location was made more salient, significant parafoveal semantic priming occurred only at 80 ms (Experiment 3). Finally, with short primes only (20, 40, 60 ms), effects were not significant but were numerically in the expected direction for 40 and 60 ms (Experiment 4). In all experiments, fixation durations on the target word increased with prime durations under all conditions. The evidence for extraction of semantic information from the parafoveal word favors an explanation in terms of parallel word processing in reading. |
Lynn Huestegge Effects of vowel length on gaze durations in silent and oral reading Journal Article In: Journal of Eye Movement Research, vol. 3, no. 5, pp. 1–18, 2010. @article{Huestegge2010a, Vowel length is known to affect reaction times in single word reading. Eye movement studies involving silent sentence reading showed that phonological information of a word can be acquired even before it is fixated. However, it remained an open question whether vowel length directly influences oculomotor control in sentence reading. In the present eye tracking study, subjects read sentences that included target words of varying vowel length and frequency. In Experiment 1, subjects read silently for comprehension, whereas Experiment 2 involved oral reading. Experiments 3 and 4 additionally included an articulatory suppression task and a foot tapping task. Results indicated that in conditions that did not require additional articulation (Experiments 1 and 4) gaze durations were increased for words with long vowels compared to words with short vowels. Conditions that required simultaneous articulation (Experiments 2 and 3) did not yield a vowel length effect. The results point to an influence of phonetic properties on oculomotor control during silent reading around the time of the completion of lexical access. |
Lynn Huestegge; Diana Bocianski Effects of syntactic context on eye movements during reading Journal Article In: Advances in Cognitive Psychology, vol. 6, no. 6, pp. 79–87, 2010. @article{Huestegge2010b, Previous research has demonstrated that properties of a currently fixated word and of adjacent words influence eye movement control in reading. In contrast to such local effects, little is known about the global effects on eye movement control, for example global adjustments caused by processing difficulty of previous sentences. In the present study, participants read text passages in which voice (active vs. passive) and sentence structure (embedded vs. non-embedded) were manipulated. These passages were followed by identical target sentences. The results revealed effects of previous sentence structure on gaze durations in the target sentence, implying that syntactic properties of previously read sentences may lead to a global adjustment of eye movement control. |
Lynn Huestegge; Hanns Jürgen Kunert; Ralph Radach Long-term effects of cannabis on eye movement control in reading Journal Article In: Psychopharmacology, vol. 209, no. 1, pp. 77–84, 2010. @article{Huestegge2010d, INTRODUCTION: Cannabis is known to produce substantial acute effects on human cognition and visuomotor skills. Many recent studies additionally revealed rather long-lasting effects on basic oculomotor control, especially after chronic use. However, it is still unknown to what extent these deficits play a role in everyday tasks that strongly rely on an efficient saccade system, such as reading. MATERIALS AND METHODS: In the present study, eye movements during sentence reading of 20 healthy long-term cannabis users (without acute tetrahydrocannabinol-intoxication) and 20 control participants were compared. Analyses focused on both spatial and temporal parameters of oculomotor control during reading. RESULTS: Long-term cannabis users exhibited increased fixation durations, more revisiting of previously inspected text, and a substantial prolongation of word viewing times, which were highly inflated for longer and less frequent words. DISCUSSION: The results indicate that relatively subtle performance deficits on the level of basic oculomotor control scale up as task complexity and cognitive demands increase. |
Falk Huettig; Jidong Chen; Melissa Bowerman; Asifa Majid In: Journal of Cognition and Culture, vol. 10, no. 1-2, pp. 39–58, 2010. @article{Huettig2010a, In two eye-tracking studies we investigated the influence of Mandarin numeral classifiers – a grammatical category in the language – on online overt attention. Mandarin speakers were presented with simple sentences through headphones while their eye-movements to objects presented on a computer screen were monitored. The crucial question is what participants look at while listening to a pre-specified target noun. If classifier categories influence Mandarin speakers' general conceptual processing, then on hearing the target noun they should look at objects that are members of the same classifier category – even when the classifier is not explicitly present (cf., Huettig and Altmann, 2005). The data show that when participants heard a classifier (e.g., ba3, Experiment 1) they shifted overt attention significantly more to classifiermatch objects (e.g., chair) than to distractor objects, but when the classifier was not explicitly presented in speech, overt attention to classifier-match objects and distractor objects did not differ (Experiment 2). This suggests that although classifier distinctions do influence eye-gaze behavior, they do so only during linguistic processing of that distinction and not in moment-to-moment general conceptual processing. |
Falk Huettig; Robert J. Hartsuiker Listening to yourself is like listening to others: External, but not internal, verbal self-monitoring is based on speech perception Journal Article In: Language and Cognitive Processes, vol. 25, no. 3, pp. 347–374, 2010. @article{Huettig2010, Theories of verbal self-monitoring generally assume an internal (pre-articu- latory) monitoring channel, but there is debate about whether this channel relies on speech perception or on production-internal mechanisms. Perception- based theories predict that listening to one's own inner speech has similar behavioural consequences as listening to someone else's speech. Our experi- ment therefore registered eye-movements while speakers named objects accompanied by phonologically related or unrelated written words. The data showed that listening to one's own speech drives eye-movements to phonolo- gically related words, just as listening to someone else's speech does in perception experiments. The time-course of these eye-movements was very similar to that in other-perception (starting 300 ms post-articulation), which demonstrates that these eye-movements were driven by the perception of overt speech, not inner speech. We conclude that external, but not internal monitoring, is based on speech perception. |
Jukka Hyönä; Raymond Bertram Do frequency characteristics of nonfixated words influence the processing of fixated words during reading? Journal Article In: European Journal of Cognitive Psychology, vol. 16, no. 1-2, pp. 104–127, 2010. @article{Hyoenae2010, Are readers capable of lexically processing more than one word at a time? In five eye movement experiments, we examined to what extent lexical characteristics of the nonfixated word to the right of fixation influenced readers' eye behavior on the fixated word. In three experiments, we varied the frequency of the initial constituent of two-noun compounds, while in two experiments the whole-word frequency was manipulated. The results showed that frequency characteristics of the parafoveal word sometimes affected eye behavior prior to fixating it, but the direction of effects was not consistent & the effects were not replicated across all experiments. Follow-up regression analyses suggested that foveal & parafoveal word length as well as the frequency of the word-initial trigram of the parafoveal word may modulate the parafoveal-on-foveal effects. It is concluded that low-frequency words or lexemes may under certain circumstances serve as a magnet to attract an early eye movement to them. However, further corroborative evidence is clearly needed. |

Greenberg The size and direction of saccadic curvatures during reading Journal Article In: Vision Research, vol. 50, no. 12, pp. 1117–1130, 2010. @article{Inhoff2010, Eye movements during the reading of multi-line pages of texts were analyzed to determine the trajectory of reading saccades. The results of two experiments showed that the trajectory of the majority of forward-directed saccades was negatively biased, i.e., the trajectory fell below the start and end location of the saccadic movement. This is attributed to a global top-to-bottom orienting of attention. The curvature size and the proportion of negative trajectories were diminished when linguistic processing demands were high and when the beginning lines of a page were read. Longer pre-saccadic fixations also yielded smaller saccadic curvatures, and they resulted in fewer negatively curved forward-directed saccades in Experiment 1 although not in Experiment 2. These findings indicate that the top-to-bottom pull of saccadic trajectories is modulated by processing demands and processing opportunities. The results are in general agreement with a time-locked attraction–inhibition hypothesis, according to which the horizontal movement component of a saccade is initially subject to an automatic top-to-bottom orienting of attention that is subsequently inhibited. |
Angela M. Isaacs; Duane G. Watson Accent detection is a slippery slope: Direction and rate of F0 change drives listeners' comprehension Journal Article In: Language and Cognitive Processes, vol. 25, no. 7-9, pp. 1178–1200, 2010. @article{Isaacs2010, The present study tests whether listeners use F0, duration, or some combination of the two to identify the presence of an accented word in a short discourse. Participants' eye movements to previously mentioned and new objects were monitored as participants listened to instructions to move objects in a display. The name of the target object on critical trials was resynthesized from naturally-produced utterances so that it had either high or low F0 and either long or short duration. Fixations to the new object were highest when there was a steep rise in F0. Fixations to the previously mentioned object were highest when there was a steep drop in F0. These results suggest that listeners use F0 slope to make decisions about the presence of an accent, and that F0 and duration by themselves do not solely determine accent interpretation. |

However, there have been few systematic investigations of individual differences. Such an investigation could help refine models of word recognition by indicating which processing parameters are likely to vary, and could also have important implications for work on language impairment. The present study begins to fill this gap by relating individual differences in overall language ability to variation in online word recognition processes. Using the visual world paradigm, we evaluated online spoken word recognition in adolescents who varied in both basic language abilities and non-verbal cognitive abilities. Eye movements to target, cohort and rhyme objects were monitored during spoken word recognition, as an index of lexical activation. Adolescents with poor language skills showed fewer looks to the target and more fixations to the cohort and rhyme competitors. These results were compared to a number of variants of the TRACE model (McClelland & Elman, 1986) that were constructed to test a range of theoretical approaches to language impairment: impairments at sensory and phonological levels; vocabulary size, and generalized slowing. None of the existing approaches were strongly supported, and variation in lexical decay offered the best fit. Thus, basic word recognition processes like lexical decay may offer a new way to characterize processing differences in language impairment. |

Nikole D. Patson; Tessa Warren Eye movements when reading implausible sentences: Investigating potential structural influences on semantic integration Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 8, pp. 1516–1532, 2010. @article{Patson2010, The disruption that occurs in response to reading about implausible events in unambiguous sentences can be informative about the time course of semantic interpretation (e.g. Hagoort, Hald, Bastiaansen, & Petersson, 2004; Nieuwland & Van Berkum, 2006; Warren & McConnell, 2007). Two eye-tracking studies used implausible sentences to investigate whether local factors like the structural relationships and the distance between words cueing a plausibility violation influence how quickly those words are integrated into a global semantic interpretation. Experiment 1 suggested that eye-movement disruption was unaffected by the number of words intervening between the words cueing the implausibility. Experiment 2 demonstrated that eye-movement disruption to implausibility occurred along the same time course regardless of whether the words cueing the implausibility were in a theta-assigning relation or not. These results suggest that these local structural factors do not influence how quickly new words are integrated into a semantic representation, but rather the global event representation determines the time course over which implausibility is detected. |

One interesting case involves decisions about telicity: whether expressions refer to events that are determinate versus indeterminate with respect to an endpoint. Thus, the insect hopped is apparently determinate, but continuing with a clause beginning with until, in which case hopped must be interpreted as an ongoing activity, is possible. Studies using secondary lexical decision and "stop-making-sense" tasks found that comprehenders experienced difficulty with these continuations, compatible with full commitment (Pinango, Zurif, & Jackendoff, 1999; Todorova, Straub, Badecker, & Frank, 2000a, 2000b). However, we report 2 self-paced reading and 2 eye-tracking experiments that indicate readers do not experience any difficulty with these types of mismatches in telicity. We argue that during normal reading, comprehenders do not immediately need to commit fully to the telicity of events and that full commitment may only occur when processing demands induce immediate decisions. We contrast these results with evidence for full commitment in complement coercions, for example, began the book (McElree, Traxler, Pickering, Seely, & Jackendoff, 2001) and other forms of semantic interpretation. |

The present experiment embedded ambiguous trimorphemic words in sentence contexts, manipulated whether or not preceding context disambiguated the meaning, and examined the pattern of fixation durations on the ambiguous word and the remainder of the text. The results indicated that the unlock-able interpretation was preferred; moreover, preceding context did not exert a significant effect until the eyes had initially exited from the target word. |
Gerardo Cepeda Porras; Yann Gaël Guéhéneuc An empirical study on the efficiency of different design pattern representations in UML class diagrams Journal Article In: Empirical Software Engineering, vol. 15, no. 5, pp. 493–522, 2010. @article{Porras2010, Design patterns are recognized in the software engineering community as useful solutions to recurring design problems that improve the quality of programs. They are more and more used by developers in the design and implementation of their programs. Therefore, the visualization of the design patterns used in a program could be useful to efficiently understand how it works. Currently, a common representation to visualize design patterns is the UML collaboration notation. Previous work noticed some limitations in the UML representation and proposed new representations to tackle these limitations. However, none of these pieces of work conducted empirical studies to compare their new representations with the UML representation. We designed and conducted an empirical study to collect data on the performance of developers on basic tasks related to design pattern comprehension (i.e., identifying composition, role, participation) to evaluate the impact of three visual representations and to compare them with the UML one. We used eye-trackers to measure the developers' effort during the execution of the study. Collected data and their analyses show that stereotype-enhanced UML diagrams are more efficient for identifying composition and role than the UML collaboration notation. The UML representation and the pattern-enhanced class diagrams are more efficient for locating the classes participating in a design pattern (i.e., identifying participation). |

A dual description of writing processes was undertaken, based on (a) the respective time courses of these processes, as assessed by an analysis of eye and pen movements, and (b) the semantic characteristics of the writers' scripts. To conduct a more fine-grained description of processing strategies, a ‘‘case study'' approach was adopted, whereby a comprehensive range of measures was used to assess processes within five writers with different levels of expertise. The task was to continue writing a story based on excerpt from a source document (incipit). The main results showed two developmental patterns linked to expertise: (a) a gradual acceleration in low- and high-level processing (pauses, flow), associated with (b) changes in the way the previous text was (re)read. |
David Caplan Task effects on BOLD signal correlates of implicit syntactic processing Journal Article In: Language and Cognitive Processes, vol. 25, no. 6, pp. 866–901, 2010. @article{Caplan2010, BOLD signal was measured in sixteen participants who made timed font change detection judgments in visually presented sentences that varied in syntactic structure and the order of animate and inanimate nouns. Behavioral data indicated that sentences were processed to the level of syntactic structure. BOLD signal increased in visual association areas bilaterally and left supramarginal gyrus in the contrast of sentences with object- and subject-extracted relative clauses without font changes in which the animacy order of the nouns biased against the syntactically determined meaning of the sentence. This result differs from the findings in a non-word detection task (Caplan et al, 2008a), in which the same contrast led to increased BOLD signal in the left inferior frontal gyrus. The difference in areas of activation indicates that the sentences were processed differently in the two tasks. These differences were further explored in an eye tracking study using the materials in the two tasks. Issues pertaining to how parsing and interpretive operations are affected by a task that is being performed, and how this might affect BOLD signal correlates of syntactic contrasts, are discussed. |
Paul E. Engelhardt; Fernanda Ferreira; Elena G. Patsenko Pupillometry reveals processing load during spoken language comprehension Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 4, pp. 639–645, 2010. @article{Engelhardt2010, This study investigated processing effort by measuring peoples' pupil diameter as they listened to sentences containing a temporary syntactic ambiguity. In the first experiment, we manipulated prosody. The results showed that when prosodic structure conflicted with syntactic structure, pupil diameter reliably increased. In the second experiment, we manipulated both prosody and visual context. The results showed that when visual context was consistent with the correct interpretation, prosody had very little effect on processing effort. However, when visual context was inconsistent with the correct interpretation, prosody had a large effect on processing effort. The interaction between visual context and prosody shows that visual context has an effect on online processing and that it can modulate the influence of linguistic sources of information, such as prosody. Pupillometry is a sensitive measure of processing effort during spoken language comprehension. |
Cara R.

" when the pronoun following because was incongruent with the bias of the implicit-causality verb. The authors suggested that these immediate delays could be attributed to participants predicting a bias-congruent pronoun after because. According to this explanation, any other word placed after because should cause processing delays. The present investigation aimed to test this explanation by using sentences of the form "David blamed Linda because she(bias-congruent)/he(bias-incongruent)/there(bias-neutral) . . . ". Since significant immediate delays were observed in sentences containing a bias-incongruent pronoun (relative to a bias-congruent pronoun) but not in sentences containing there, the results of this study support an immediate integration effect but pose a problem to the word-specific prediction account of the implicit causality effect. |

Two essential ingredients of everyday cognition that are employed during language comprehension are the ability to reason counterfactually, and the ability to understand and predict other peoples' behaviour by attributing independent mental states to them (theory of mind).We report two visual-world studies investigating the extent to which the constraints of world knowledge and prior context, as established by a counterfactual (Exp. 1) or a false belief situation (Exp. 2), influence eye-movements directed towards objects in a visual field. Proportions of anticipatory eye-movements indicated an initial visual bias towards contextually supported referents in both studies. Thus, we propose that when visual information is available to reinforce linguistic input, participants expect a context-relevant continuation. Shortly after the critical word onset, the linguistically supported referent was visually favoured, with counterfactual (but not false belief) contexts revealing a temporal delay in integrating factually inconsistent language input. Results are discussed in relation to accounts of discourse processing and the processing relationship between counterfactual and theory of mind reasoning. Finally, we compare findings across different experimental paradigms and propose a novel cluster-analytic procedure to identify time-windows of interest in visual-world data. |
Ruth Filik; Linda M.

Specifically, participants' eye movements were recorded while they read sentences which were either intended ironically, or non-ironically, and subsequent text which contained pronominal reference to the ironic (or non-ironic) phrase. Results showed longer reading times for ironic comments compared to a non-ironic baseline, suggesting that additional processing was required in ironic compared to non-ironic conditions. Reading times for subsequent pronominal reference indicated that for ironic materials, both the ironic and literal interpretations of the text were equally accessible during on-line language comprehension. This finding is most in-line with predictions of the graded salience hypothesis, which, in conjunction with the retention hypothesis, states that readers represent both the literal and ironic interpretation of an ironic utterance. |

Participants were 9 individuals with Down syndrome ranging in reading level from Grades 1 to 3 and a reading-level-matched control group. For syntactically simple sentences, the pattern of reading times was similar for the two groups, with longer reading times found at sentence end. This "wrap-up" effect was also found in the first reading of more complex sentences for the control group, whereas it only emerged later for the readers with Down syndrome. Our results provide evidence that eye movements can be used to investigate reading in individuals with Down syndrome and underline the need for future studies. |
Linda M. Moxey; Ruth Filik The effects of character desire on focus patterns and pronominal reference following quantified statements Journal Article In: Discourse Processes, vol. 47, no. 7, pp. 588–616, 2010. @article{Moxey2010, Following a positively quantified statement such as, oA few of the children sang the chorus,o a plural pronoun is likely to refer to the set of children who sang (the reference set). Negative natural language quantifiers (NLQs) such as few or not many, on the other hand, are more likely to be followed by reference to the complement set of children who did not sing. According to the presupposition-denial account of negative NLQs, the complement set is available for pronominal reference following these expressions because they imply a shortfall between the amount denoted and a presupposed larger amount. Focus on the shortfall set is effectively focus on the complement set. Previous support for this account is largely based on a series of experiments which show that complement set focus is also possible following positive NLQs if a previously mentioned character expects a larger amount, thereby creating a shortfall between the character's expectations and the amount denoted by the NLQ. It is not clear, however, whether the shortfall implied by a negative NLQ must be based on expectation per se, or whether the NLQ-based implication is more general. This article reports 3 experiments which show that a shortfall can also be created between an NLQ and a character's desire for a particular quantity. Results suggest that the implication of negative NLQs that a larger amount is denied need not be based on expectation, but may be less specific. |

Two experiments tested their implicit and explicit knowledge about manipulable objects in order to examine whether such deficits accompany impairment in the conceptual representation of manipulation features. An eyetracking method was used to test implicit knowledge (Experiment 1): participants viewed a visual display on a computer screen and touched the corresponding object in response to an auditory input. Manipulation relationship among objects was not task-relevant, and thus the assessment of manipulation knowledge was implicit. Like the non-apraxic control patients, apraxic patients fixated on an object picture (e.g., " typewriter" ) that was manipulation-related to a target word (e.g., 'piano') significantly more often than an unrelated object picture (e.g., " bucket" ) as well as a visual control (e.g., " couch" ). However, this effect emerged later than in the non-apraxic control group, suggesting impaired access to manipulation features in the apraxic group. In the semantic judgment task (Experiment 2), participants were asked to make an explicit judgment about the relationship of picture triplets of manipulable objects by choosing the pair with similar manipulation features. Apraxic patients performed significantly worse on this task than the non-apraxic control group. Both implicit and explicit measures of manipulation knowledge show that apraxia is not merely a perceptuomotor deficit of skilled movements, but results in a concomitant impairment in representing manipulation features and accessing them for cognitive processing. |
Mariko Nakayama; Christopher R. Sears; Stephen J. Lupker Testing for lexical competition during reading: Fast priming with orthographic neighbors Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 36, no. 2, pp. 477–492, 2010. @article{Nakayama2010, Recent studies have found that masked word primes that are orthographic neighbors of the target inhibit lexical decision latencies (Davis & Lupker, 2006; Nakayama, Sears, & Lupker, 2008), consistent with the predictions of lexical competition models of visual word identification (e.g., Grainger & Jacobs, 1996). In contrast, using the fast priming paradigm (Sereno & Rayner, 1992), orthographically similar primes produced facilitation in a reading task (H. Lee, Rayner, & Pollatsek, 1999; Y. Lee, Binder, Kim, Pollatsek, & Rayner, 1999). Experiment 1 replicated this facilitation effect using orthographic neighbor primes. In Experiment 2, neighbor primes and targets were presented in different cases (e.g., SIDE-tide); in this situation, the facilitation effect disappeared. However, nonword neighbor primes (e.g., KIDE-tide) still significantly facilitated reading of targets (Experiment 3). Taken together, these results suggest that it is possible to explain the priming effects from word neighbor primes in fast priming experiments in terms of the interactions between the inhibitory and facilitory processes embodied in lexical competition models. |

Gordon; Yoonhyoung Lee; Robert Kluender Cognitive and linguistic factors affecting subject/object asymmetry: An eye-tracking study of prenominal relative clauses in Korean Journal Article In: Language, vol. 86, no. 3, pp. 546–582, 2010. @article{NayoungKwon2010, The morphology of the telencephalon displays great diversity among different vertebrate lineages. Particularly, the everted telencephalon of ray-finned fishes shows a noticeably different morphology to the evaginated telencephalon of non-ray-finned fishes and other vertebrates. This makes the comparison between the different parts of the telencephalon of ray-finned fishes and other vertebrates difficult. Based on neuroanatomical, neurochemical and connectional data no consensus on the subdivisions of the adult telencephalon of ray-finned fishes and their relation to nuclei in the telencephalon of other vertebrates has been reached yet. For tetrapods, comparative expression pattern analysis of homologous developmental genes has been a successful approach to clarify homologies between different parts of the telencephalon. In the larval zebrafish, subdivisions of the subpallium have been proposed using conserved developmental genes expression. In this study, we investigate the subdivisions of the adult zebrafish telencephalon by analyzing the expression pattern of conserved molecular marker genes. We identify the boundary between the pallium and subpallium based on the complementary expression of dlx2a, dlx5a in the subpallium and tbr1, neurod in the pallium. Furthermore, combinatorial expression of Isl, nkx2.1b, lhx1b, tbr1, eomesa, emx1, emx2 and emx3 identifies striatal-like, pallidal-like and septal-like subdivisions within the subpallium. In contrast to previous models, we propose that the striatum and pallidum are stretched along the rostro-caudal axis of the telencephalon. Further, the septal nuclei derive from both the pallium and subpallium. On this basis, we present a new model for the subdivisions of the subpallium in teleost fish. |

Sanford Effects of intensionality on sentence and discourse processing: Evidence from eye-movements Journal Article In: Journal of Memory and Language, vol. 62, no. 4, pp. 352–379, 2010. @article{Delogu2010, Intensional verbs like want select for clausal complements expressing propositions, though they can be perfectly natural when combined with a direct object. There are two interesting phenomena associated with intensional transitive expressions. First, it has been suggested that their interpretation requires enriched compositional operations, similarly to expressions like began the book (e.g., Pustejovsky, 1995). Secondly, when the object position is filled by an indefinite NP, it preferentially receives an unspecific reading, under which definite anaphora is not supported (e.g., Moltmann, 1997). We report three eye-tracking experiments investigating the time-course of processing of sentence pairs like John wanted a beer. The beer was warm. Consistent with the enriched composition hypothesis, results showed that intensional transitive constructions (e.g., wanted a beer) take longer to process than control expressions (e.g., drank/wanted to drink a beer). However, contrary to previous findings, the processing of the continuation sentence appears to be not affected by whether the definite NP (the beer) can be interpreted as coreferential with the indefinite or not. We interpret the results with respect to accounts of semantic processing relying on the notions of enriched composition and non-actuality implicature. |
Denis Drieghe; Alexander Pollatsek; Barbara J. Juhasz; Keith Rayner Parafoveal processing during reading is reduced across a morphological boundary Journal Article In: Cognition, vol. 116, no. 1, pp. 136–142, 2010. @article{Drieghe2010, A boundary change manipulation was implemented within a monomorphemic word (e.g., fountaom as a preview for fountain), where parallel processing should occur given adequate visual acuity, and within an unspaced compound (bathroan as a preview for bathroom), where some serial processing of the constituents is likely. Consistent with that hypothesis, there was no effect of the preview manipulation on fixation time on the 1st constituent of the compound, whereas there was on the corresponding letters of the monomorphemic word. There was also a larger preview disruption on gaze duration on the whole monomorphemic word than on the compound, suggesting more parallel processing within monomorphemic words. |
Brianna M. Eiter; Albrecht W. Inhoff Visual word recognition during reading is followed by subvocal articulation Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 36, no. 2, pp. 457–470, 2010. @article{Eiter2010, Three experiments examined whether the identification of a visual word is followed by its subvocal articulation during reading. An irrelevant spoken word (ISW) that was identical, phonologically similar, or dissimilar to a visual target word was presented when the eyes moved to the target in the course of sentence reading. Sentence reading was further accompanied by either a sequential finger tapping task (Experiment 1) or an articulatory suppression task (Experiment 2). Experiment 1 revealed sound-specific interference from a phonologically similar ISW during posttarget viewing. This interference was absent in Experiment 2, where similar and dissimilar ISWs impeded target and posttarget reading equally. Experiment 3 showed that articulatory suppression left the lexical processing of visual words intact and that it did not diminish the influence of visual word recognition on eye guidance. The presence of sound-specific interference during posttarget reading in Experiment 1 is attributed to deleterious effects of a phonologically similar ISW on the subvocal articulation of a target. Its absence in Experiment 2 is attributed to the suppression of a target's subvocal articulation. |

Tanenhaus "Some," and possibly all, scalar inferences are not delayed: Evidence for immediate pragmatic enrichment Journal Article In: Cognition, vol. 116, no. 1, pp. 42–55, 2010. @article{Grodner2010, Scalar inferences are commonly generated when a speaker uses a weaker expression rather than a stronger alternative, e.g., John ate some of the apples implies that he did not eat them all. This article describes a visual-world study investigating how and when perceivers compute these inferences. Participants followed spoken instructions containing the scalar quantifier some directing them to interact with one of several referential targets (e.g., Click on the girl who has some of the balloons). Participants fixated on the target compatible with the implicated meaning of some and avoided a competitor compatible with the literal meaning prior to a disambiguating noun. Further, convergence on the target was as fast for some as for the non-scalar quantifiers none and all. These findings indicate that the scalar inference is computed immediately and is not delayed relative to the literal interpretation of some. It is argued that previous demonstrations that scalar inferences increase processing time are not necessarily due to delays in generating the inference itself, but rather arise because integrating the interpretation of the inference with relevant information in the context may require additional time. With sufficient contextual support, processing delays disappear. |

More specifically, we examined whether readers extract more parafoveal information from a compound word's second constituent than from the same word when it is the noun in an adjective-noun phrase (kummitustarina "ghost story" vs. lennokas tarina "vivid story"). We also examined whether the processing of compound word constituents is serial or parallel and how parafoveal word processing develops over the elementary school years. Participants were Finnish adults and 8-year-old second-, 10-year-old fourth-, and 12-year-old sixth-graders. The results showed that for all age groups more parafoveal information is extracted from the second constituent within compounds than from the noun in adjective-noun phrases. Moreover, for all age groups we found evidence for parallel processing of constituents within compounds, but only when the compounds were of high frequency. In sum, the present study shows that attentional allocation extends further to the right and is more simultaneous when words are linguistically and spatially unified, providing evidence that attention in text processing is flexible in nature. |
Stefan Hawelka; Benjamin Gagl; Heinz Wimmer A dual-route perspective on eye movements of dyslexic readers Journal Article In: Cognition, vol. 115, no. 3, pp. 367–379, 2010. @article{Hawelka2010, This study assessed eye movement abnormalities of adolescent dyslexic readers and interpreted the findings by linking the dual-route model of single word reading with the E-Z Reader model of eye movement control during silent sentence reading. A dysfunction of the lexical route was assumed to account for a reduced number of words which received only a single fixation or which were skipped and for the increased number of words with multiple fixations and a marked effect of word length on gaze duration. This pattern was interpreted as a frequent failure of orthographic whole-word recognition (based on orthographic lexicon entries) and on reliance on serial sublexical processing instead. Inefficiency of the lexical route was inferred from prolonged gaze durations for singly fixated words. These findings were related to the E-Z Reader model of eye movement control. Slow activation of word phonology accounted for the low skipping rate of dyslexic readers. Frequent reliance on sublexical decoding was inferred from a tendency to fixate word beginnings and from short forward saccades. Overall, the linkage of the dual-route model of single word reading and a model of eye movement control led to a useful framework for understanding eye movement abnormalities of dyslexic readers. |
Martin Corley Making predictions from speech with repairs: Evidence from eye movements Journal Article In: Language and Cognitive Processes, vol. 25, no. 5, pp. 706–727, 2010. @article{Corley2010, When listeners hear a spoken utterance, they are able to predict upcoming information on the basis of what they have already heard. But what happens when the speaker changes his or her mind mid-utterance? The present paper investigates the immediate effects of repairs on listeners' linguistic predictions. Participants listened to sentences like the boy will eat/move the cake while viewing scenes depicting the agent, the theme, and distractor objects (which were not edible). Over 25% of items included conjoined verbs (eat and move) and 25% included repairs (eat- uh, move). Participants were sensitive to repairs: where eat was overridden by move, fixations on the theme patterned with the plain move condition, but where there was a conjunct, fixations patterned with eat. However, once the theme had been heard, there were more fixations to the cake in all conditions including eat, showing that the first verb maintained an influence on prediction, even following a repair. The results are compatible with the view that prediction during comprehension is updated incrementally, but not completely, as the linguistic input unfolds. |

Richter; Antje Nuthmann; Hua Shu Flexible saccade-target selection in Chinese reading Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 4, pp. 705–725, 2010. @article{Yan2010, As Chinese is written without orthographical word boundaries (i.e., spaces), it is unclear whether saccade targets are selected on the basis of characters or words and whether saccades are aimed at the beginning or the centre of words. Here, we report an experiment where 30 Chinese readers read 150 sentences while their eye movements were monitored. They exhibited a strong tendency to fixate at the word centre in single-fixation cases and at the word beginning in multiple-fixation cases. Different from spaced alphabetic script, initial fixations falling at the end of words were no more likely to be followed by a refixation than initial fixations at word centre. Further, single fixations were shorter than first fixations in two-fixation cases, which is opposite to what is found in Roman script. We propose that Chinese readers dynamically select the beginning or centre of words as saccade targets depending on failure or success with segmentation of parafoveal word boundaries. |

This experiment examined parafoveal processing during reading of Chinese sentences, using a boundary manipulation of N + 2-word preview with low- and high-frequency words N + 1. The main findings were (a) an identity PB for word N + 2 that was (b) primarily observed when word N + 1 was of high frequency (i.e., an interaction between frequency of word N + 1 and PB for word N + 2), and (c) a parafoveal-on-foveal frequency effect of word N + 1 for fixation durations on word N. We discuss implications for theories of serial attention shifts and parallel distributed processing of words during reading. |

McConkie Pay now or pay later: Aging and the role of boundary salience in self-regulation of conceptual Iintegration in sentence processing Journal Article In: Psychology and Aging, vol. 25, no. 1, pp. 168–176, 2010. @article{StineMorrow2010, Previous research has suggested that older readers may self-regulate input during reading differently from the way younger readers do, so as to accommodate age-graded change in processing capacity. For example, older adults may pause more frequently for conceptual integration. Presumably, such an allocation policy would enable older readers to manage the cognitive demands of constructing a semantic representation of the text by off-loading the products of intermediate computations to long-term memory, thus decreasing memory demands as conceptual load increases. This was explicitly tested in 2 experiments measuring word-by-word reading time for sentences in which boundary salience was manipulated but in which semantic content was controlled. With both a computer-based moving-window paradigm that permits only forward eye movements, and an eye-tracking paradigm that allows measurement of regressive eye movements, we found evidence for the proposed tradeoff between early and late wrap-up. Across the 2 experiments, age groups were more similar than different in regulating processing time. However, older adults showed evidence of exaggerated early wrap-up in both experiments. These data are consistent with the notion that readers opportunistically regulate effort and that older readers can use this to good advantage to maintain comprehension. |
Patrick Sturt; Frank Keller; Amit Dubey Syntactic priming in comprehension: Parallelism effects with and without coordination Journal Article In: Journal of Memory and Language, vol. 62, no. 4, pp. 333–351, 2010. @article{Sturt2010, Although previous research has shown a processing facilitation for conjoined phrases that share the same structure, it is currently not clear whether this parallelism advantage is specific to particular syntactic environments such as coordination, or whether it is an example of more general effect in sentence comprehension. Here, we report three eye-tracking experiments that test for parallelism effects both in coordinated noun phrases and in subordinate clauses. The first experiment replicated previous findings, showing that the second conjunct of a coordinated noun phrase was read more quickly when it had the same structure as the first conjunct, compared with when it did not. Experiment 2 examined parallelism effects in noun phrases that were not linked by coordination. Again, a reading time advantage was found when the second noun phrase had the same structure as the first. Experiment 3 compared parallelism effects in coordinated and non-coordinated syntactic environments. The parallelism effect was replicated for both environments, and was statistically equivalent whether or not coordination was involved. This demonstrated that parallelism effects can be found outside the environment of coordination, suggesting a general syntactic priming mechanism as the underlying explanation. |
Mark Torrance Grammatical planning, execution, and control in written sentence production Journal Article In: Reading and Writing, vol. 23, no. 7, pp. 777–801, 2010. @article{Torrance2010, In this study participants were asked to describe pictured events in one type-written sentence, containing one of two different syntactic structures (subordinated vs. coordinated subject noun phrases). According to the hypothesis, the larger subordinated structure (one noun phrase including a second, subordinated, one) should be cognitively more costly and will be planned before the start of the production, whereas the coordinated structure, consisting of two syntactically equal noun phrases, can be planned locally in an incremental fashion. The hypothesis was confirmed by the analysis of the word-initial keystroke latencies as well as the eye movements towards the stimulus, indicating a stronger tendency to incremental planning in case of the coordinated structure. |
Yiu-Kei Tsang; Hsuan-Chih Chen Morphemic ambiguity resolution in chinese: Activation of the subordinate meaning with a prior dominant-biased context Journal Article In: Psychonomic Bulletin & Review, vol. 17, no. 6, pp. 875–881, 2010. @article{Tsang2010, In the present study, we examined how morphemic ambiguity is resolved using the visual-world paradigm. Participants were presented with Chinese bimorphemic words containing an ambiguous morpheme (analogous to the suffix -er in teacher and taller) and performed a visual search task. Their eye-movement patterns during target detection showed that (1) without a prior context, the dominant meaning of an ambiguous morpheme was more available than the subordinate one; (2) with a dominant-biased prior context, the subordinate meaning was still activated; and (3) a subordinate-biased prior context could inhibit the dominant interpretation. Therefore, both the frequency of the intended meaning and the prior contextual biases play a role in morphemic ambiguity resolution. The results are discussed with reference to models of ambiguity resolution and recent proposals of the graded nature of morphological effects. |
Lise Van der Haegen; Denis Drieghe; Marc Brysbaert The split fovea theory and the Leicester critique: What do the data say? Journal Article In: Neuropsychologia, vol. 48, no. 1, pp. 96–106, 2010. @article{VanderHaegen2010, According to the Split Fovea Theory (SFT) recognition of foveally presented words involves interhemispheric transfer. This is because letters to the left of the fixation location are initially sent to the right hemisphere, whereas letters to the right of the fixation position are projected to the left hemisphere. Both sources of information must be integrated for words to be recognized. Evidence for the SFT comes from the Optimal Viewing Position (OVP) paradigm, in which foveal word recognition is examined as a function of the letter fixated. OVP curves are different for left and right language dominant participants, indicating a time cost when information is presented in the half-field ipsilateral to the dominant hemisphere (Hunter, Brysbaert, & Knecht, 2007). The methodology of the SFT research has recently been questioned, because not enough efforts were made to ensure adequate fixation. The aim of the present study is to test the validity of this argument. Experiment 1 replicated the OVP effect in a naming task by presenting words at different fixation positions, with the experimental settings applied in previous OVP research. Experiment 2 monitored and controlled eye fixations of the participants and presented the stimuli within the boundaries of the fovea. Exactly the same OVP curve was obtained. In Experiment 3, the eyes were also tracked and monocular viewing was used. Results again revealed the same OVP effect, although latencies were remarkably higher than in the previous experiments. From these results we can conclude that although noise is present in classical SFT studies without eye-tracking, this does not change the OVP effect observed with left dominant individuals. |

What does eyetracking research tell us about the interaction between reading and writing processes during text production?/ Guest Edited by L. Van Waes, M. Leijten and A. Wengelin In this study we investigated the role of reading, how writers coordinate editing with other writing processes. In particular, the experiment examines how the cognitive demands of sentence composing and the type of error influence the reading and writing performance. We devised an experimental writing task in which participants corrected an embedded error (orthographic near-neighbors or far-neighbors) and completed a sentence (using 1 or 3 context words)–in either order. Data were collected by logging keystrokes and recording eye-movements. The results revealed that both error and sentence complexity influenced the approach to error-correcting. Participants generally completed the partial sentence first, and then corrected the error (approximately 90% of the items). Task complexity reinforced this tendency. Moreover, in most of these cases, the error was fixated at least once prior to sentence completion. This suggests that the error was detected (at least partially), but the correction response was inhibited. The differences in cognitive load also affect the reading activity during planning. This investigation illustrates how the interplay of two task factors, error and sentence complexity, appears to influence how writers coordinate error-correcting with sentence composing. |

Lewis; Sabine Kern Short-term forgetting in sentence comprehension: Crosslinguistic evidence from verb-final structures Journal Article In: Language and Cognitive Processes, vol. 25, no. 4, pp. 533–567, 2010. @article{Vasishth2010, Seven experiments using self-paced reading and eyetracking suggest that omitting the middle verb in a double centre embedding leads to easier processing in English but leads to greater difficulty in German. One commonly accepted explanation for the English pattern—based on data from offline acceptability ratings and due to Gibson and Thomas (1999)—is that working-memory overload leads the comprehender to forget the prediction of the upcoming verb phrase (VP), which reduces working-memory load. We show that this VP-forgetting hypothesis does an excellent job of explaining the English data, but cannot account for the German results. We argue that the English and German results can be explained by the parser's adaptation to the grammatical properties of the languages; in contrast to English, German subordinate clauses always have the verb in clause-final position, and this property of German may lead the German parser to maintain predictions of upcoming VPs more robustly compared to English. The evidence thus argues against language-independent forgetting effects in online sentence processing; working-memory constraints can be conditioned by countervailing influences deriving from grammatical properties of the language under study. |
Chin-An Wang; Albrecht W. Inhoff The influence of visual contrast and case changes on parafoveal preview benefits during reading Journal Article In: Quarterly Journal of Experimental Psychology, vol. 63, no. 4, pp. 805–817, 2010. @article{Wang2010, Reingold and Rayner (2006) showed that the visual contrast of a fixated target word influenced its viewing duration, but not the viewing of the next (posttarget) word in the text that was shown in regular contrast. Configurational target changes, by contrast, influenced target and posttarget viewing. The current study examined whether this effect pattern can be attributed to differential processing of the posttarget word during target viewing. A boundary paradigm (Rayner, 1975) was used to provide an informative or uninformative posttarget preview and to reveal the word when it was fixated. Consistent with the earlier study, more time was spent viewing the target when its visual contrast was low and its configuration unfamiliar. Critically, target contrast had no effect on the acquisition of useful information from a posttarget preview, but an unfamiliar target configuration diminished the usefulness of an informative posttarget preview. These findings are consistent with Reingold and Rayner's (2006) claim that saccade programming and attention shifting during reading can be controlled by functionally distinct word recognition processes. |

Participants' eye movements were monitored, and the influence of word complexity (number of strokes), word frequency, and word predictability on different eye movement measures (first-fixation duration, gaze duration, and total time) were examined. We found influences of TP on first-fixation duration and gaze duration and of LSA on total time. The results suggest that TP reflects an early stage of lexical processing while LSA reflects a later stage. |

Misalignment of the eyes should be small enough to allow sensory fusion. Recent studies reported disparity of the eyes during fixations. This study examines disconjugacy, i.e. change in disparity over time, both during saccades and fixations. Text reading saccades and saccades to single targets of similar sizes (2.5-) are compared. Young subjects were screened to avoid problems of binocular vision and oculomotor vergence. The results show high quality of motor binocular coordination in both tasks: the amplitude difference between the saccade of the eyes was approximately 0.16-; during the fixation period, the drift difference was only 0.13-. The disconjugate drift occurred mainly during the first 48 ms of fixation, was equally distributed to the eyes and was often reducing the saccade disconjugacy. Quality of coordination regardless of the task is indicative of robust physiological mechanisms. We suggest the existence of active binocular control mechanisms in which vergence signals may have a central role. Even computation of saccades may be based on continuous interaction between saccade and vergence. |

The spatial distribution of parafoveal preview benefits during reading Journal Article In: Attention, Perception, and Psychophysics, vol. 71, no. 7, pp. 1487–1494, 2009. @article{Wang2009a, Eye movements were recorded while participants read declarative sentences. Each sentence contained a criti- cal three-word sequence with a three-letter target word (n), a spatially adjacent post-target word (n+1), and a subsequent nonadjacent post-target word (n+2). The parafoveal previews of words n and n+2 were manipulated so that they were either fully visible or masked until they were fixated. The results revealed longer word n and word n+1 viewing durations when word n had been masked in the parafovea, and this occurred irrespective of whether the target was skipped or fixated. Furthermore, masking of word n diminished the usefulness of the preview of word n+2. These results indicate that the effect of a parafoveally available target preview was not strictly localized. Instead, it influenced target viewing and the viewing of the two subsequent words in the text. These results are difficult to reconcile with the assumption that attention is confined to one word at a time until that word is recognized and that attention is then shifted from the recognized word to the next. |

In Experiment 1, the critical character was replaced with a congruent or incongruent character or left unchanged. Critical character changes did not influence the fixation duration, but incongruent changes led to more regressions than congruent changes. In Experiment 2, the critical character was replaced with either a homophonic or a non-homophonic character when it was to the left of fixation. The fixation following the change was now longer when the replaced character and the critical character were homophones than when they were phonologically dissimilar. These results indicate that readers obtain phonological and semantic information to the left of a fixated character and that the recognition of consecutive Chinese characters is not strictly unidirectional. |

This result has been taken to suggest that language users are sensitive to subtle relationships between sound and syntactic function and that they make rapid use of this information in comprehension. The present article reports attempts to replicate this result using both eyetracking during normal reading (Experiment 1) and word-by-word self-paced reading (Experiment 2). No hint of a phonological typicality effect emerged on any reading-time measure in Experiment 1, nor did Experiment 2 replicate Farmer et al.'s finding from self-paced reading. Indeed, the differences between condition means were not consistently in the predicted direction, as phonologically atypical verbs were read more quickly than phonologically typical verbs, on most measures.

In the high-predictability condition, a verb strongly constrained the lexical identity of the following word, while in the low-predictability condition the target word could not be predicted on the basis of the verb. The results showed that first fixation and gaze duration on the target noun were reliably shorter in the high-predictability than in the low-predictability condition. However, initial fixation location was not affected by lexical predictability. As regards eye guidance in reading, the present study indicates that local lexical predictability influences when decisions but not where the initial fixation lands in a word. |

Cognates (e.g., Dutch-English schip [ship]) and controls were presented in a sentence context, and eye movements were monitored. Results showed faster reading times for cognates than for controls. Thus, this study shows that one of people's most automated skills, reading in one's native language, is changed by the knowledge of a second language. |

The order of the clauses was reversed so that disambiguating information either preceded or followed the ambiguous word. Context use and comprehension monitoring were examined by measuring eye fixations (Experiment 1) and self-paced reading times (Experiment 2) on the ambiguous word and disambiguating region. The results of Experiment 1 and 2 showed that poor comprehenders made use of prior context to facilitate lexical ambiguity resolution as effectively as good comprehenders but that they monitored their comprehension less effectively than good comprehenders. Good comprehenders corrected an initial interpretation error on an ambiguous word and restored comprehension once they encountered the disambiguating region. Poor comprehenders failed to deal with this type of comprehension failure. |
Heather Winskel Reading in Thai: the case of misaligned vowels Journal Article In: Reading and Writing, vol. 22, no. 1, pp. 1–24, 2009. @article{Winskel2009, Thai has its own distinctive alphabetic script with syllabic characteristics as it has implicit vowels for some consonants. Consonants are written in a linear order, but vowels can be written non-linearly above, below or to either side of the consonant. Of particular interest to the current study are that vowels can precede the consonant in writing but follow it in speech, hence a mismatch between the spoken and written sequence occurs. In order to investigate if there is a processing cost associated with this discrepancy between spoken and written sequence for vowels and the implications this has in relation to the grain size used when reading Thai, eye movements of adults reading words with and without misaligned vowels in sentences using the EyeLink II tracking system was conducted. Twenty-four university students read 50 pairs of words with misaligned and aligned vowel words matched for length and frequency embedded in same sentence frames. In addition, rapid naming data from forty adults was collected. Data from forty children 6;6-8;6 years old reading and spelling comparable words was also collected and analysed for errors. Results revealed a processing cost due to the more severely misaligned words where the vowel operates across the syllable, and gives support for a syllabic level of segmentation rather than phonemic for reading and spelling in Thai adults and children. |
Heather Winskel; Ralph Radach; Sudaporn Luksaneeyanawin Eye movements when reading spaced and unspaced Thai and English: A comparison of Thai-English bilinguals and English monolinguals Journal Article In: Journal of Memory and Language, vol. 61, no. 3, pp. 339–351, 2009. @article{Winskel2009a, The study investigated the eye movements of Thai-English bilinguals when reading both Thai and English with and without interword spaces, in comparison with English monolinguals. Thai is an alphabetic orthography without interword spaces. Participants read sentences with high and low frequency target words embedded in same sentence frames with and without interword spaces. Interword spaces had a selective effect on reading in Thai, as they facilitated word recognition, but did not affect eye guidance and lexical segmentation. Initial saccade landing positions were similar in spaced and unspaced text. As expected, removal of spaces severely disrupted reading in English, as reflected by the eye movement measures, in both bilinguals and monolinguals. Here, initial landing positions were significantly nearer the beginning of the target words when reading unspaced rather than spaced text. Effects were more accentuated in the bilinguals. In sum, results from reading in Thai give qualified support for a facilitatory function of interword spaces. |

Jinmian Yang; Suiping Wang; Hsuan-Chih Chen; Keith Rayner The time course of semantic and syntactic processing in Chinese sentence comprehension: Evidence from eye movements Journal Article In: Memory & Cognition, vol. 37, no. 8, pp. 1164–1176, 2009. @article{Yang2009, In the present study, we examined the time course of semantic and syntactic processing when Chinese is read. Readers' eye movements were monitored, and the relation between a single-character critical word and the sentence context was manipulated such that three kinds of sentences were developed: (1) congruent, (2) those with a semantic violation, and (3) those with both a semantic and a syntactic violation. The eye movement data showed that the first-pass reading times were significantly longer for the target region in the two violation conditions than in the congruent condition. Moreover, the semantic+syntactic violation caused more severe disruption than did the pure semantic violation, as reflected by longer first-pass reading times for the target region and by longer go-past times for the target region and posttarget region in the former than in the latter condition. These results suggest that the effects of, at least, a semantic violation can be detected immediately by Chinese readers and that the processing of syntactic and semantic information is distinct in both first-pass and second-pass reading.

Evidence from eye movements Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 4, pp. 1192–1204, 2009. @article{Yang2009d, The boundary paradigm (K. Rayner, 1975) was used to determine the extent to which Chinese readers obtain information from the right of fixation during reading. As characters are the basic visual unit in written Chinese, they were used as targets in Experiment 1 to examine whether readers obtain preview information from character n + 1 and character n + 2. The results from Experiment 1 suggest they do. In Experiment 2, 2-character target words were used to determine whether readers obtain preview information from word n + 2 as well as word n + 1. Robust preview effects were obtained for word n + 1. There was also evidence from gaze duration (but not first fixation duration), suggesting preview effects for word n + 2. Moreover, there was evidence for parafoveal-on-foveal effects in Chinese reading in both experiments. Implications of these results for models of eye movement control are discussed. |
Shun-Nan Yang Effects of gaze-contingent text changes on fixation duration in reading Journal Article In: Vision Research, vol. 49, no. 23, pp. 2843–2855, 2009. @article{Yang2009a, In reading, a text change during an eye fixation can increase the duration of that fixation. This increased fixation duration could be the result of disrupted text processing, or from the effect of perceiving the brief visual change (a visual transient). The present study was designed to test those two hypotheses. Subjects read multiple-line text while their eye movements were monitored. During randomly selected saccades, the text was masked with an alternate page, which was then replaced with a second alternate page, 75 or 150 ms after the onset of the subsequent (critical) fixation. The effect of the initial masking page, the text change during fixation, and the content of the second page on the likelihood of saccade initiation during the critical fixation, was measured. Results showed that a text change during fixation resulted in similar bilateral (forward and regressive) saccade suppression regardless of the nature of the first and second pages, or the timing of text change. This result likely reflects the effect of a low-level visual transient caused by text change. In addition, there was delay effect reflecting the content of the initial masking. How the suppression dissipated after text change depended on the nature of the first and second pages. These effects are attributed to high-level text processing. The present results suggest that in reading, visual and cognitive processes both can disrupt saccade initiation. The combination of processing difficulty and visually-induced saccade suppression is responsible for the change in fixation duration when gaze-contingent display change is utilized. Therefore, it is prudent to consider both factors when interpreting the effect of text change on eye movement patterns. |
Kiyomi Yatabe; Martin J. Pickering; Scott A. McDonald Lexical processing during saccades in text comprehension Journal Article In: Psychonomic Bulletin & Review, vol. 16, no. 1, pp. 62–66, 2009. @article{Yatabe2009, We asked whether people process words during saccades when reading sentences. Irwin (1998) demonstrated that such processing occurs when words are presented in isolation. In our experiment, participants read part of a sentence ending in a high- or low-frequency target word and then made a long (40 degrees) or short (10 degrees) saccade to the rest of the sentence. We found a frequency effect on the target word and the first word after the saccade, but the effect was greater for short than for long saccades. Readers therefore performed more lexical processing during long saccades than during short ones. Hence, lexical processing takes place during saccades in text comprehension. |
Eiling Yee; Eve Overton; Sharon L. Thompson-Schill Looking for meaning: Eye movements are sensitive to overlapping semantic features, not association Journal Article In: Psychonomic Bulletin & Review, vol. 16, no. 5, pp. 869–874, 2009. @article{Yee2009, Theories of semantic memory differ in the extent to which relationships among concepts are captured via associative or via semantic relatedness. We examined the contributions of these two factors, using a visual world paradigm in which participants selected the named object from a four-picture display. We controlled for semantic relatedness while manipulating associative strength by using the visual world paradigm's analogue to presenting asymmetrically associated pairs in either their forward or backward associative direction (e.g., ham-eggs vs. eggs-ham). Semantically related objects were preferentially fixated regardless of the direction of presentation (and the effect size was unchanged by presentation direction). However, when pairs were associated but not semantically related (e.g., iceberg-lettuce), associated objects were not preferentially fixated in either direction. These findings lend support to theories in which semantic memory is organized according to semantic relatedness (e.g., distributed models) and suggest that association by itself has little effect on this organization. |

Hung; Jie-Li Tsai Early parafoveal processing in reading Chinese sentences Journal Article In: Acta Psychologica, vol. 131, no. 1, pp. 24–33, 2009. @article{Yen2009, The possibility that during Chinese reading information is extracted at the beginning of the current fixation was examined in this study. Twenty-four participants read for comprehension while their eye movements were being recorded. A pretarget-target two-character word pair was embedded in each sentence and target word visibility was manipulated in two time intervals (initial 140 ms or after 140 ms) during pretarget viewing. Substantial beginning- and end-of-fixation preview effects were observed together with beginning-of-fixation effects on the pretarget. Apparently parafoveal information at least at the character level can be extracted relatively early during ongoing fixations. Results are highly relevant for ongoing debates on spatially distributed linguistic processing and address fundamental questions about how the human mind solves the task of reading within the constraints of different writing systems. |
Peng Zhou; Liqun Gao Scope processing in Chinese Journal Article In: Journal of Psycholinguistic Research, vol. 38, no. 1, pp. 11–24, 2009. @article{Zhou2009, The standard view maintains that quantifier scope interpretation results from an interaction between different modules: the syntax, the semantics as well as the pragmatics. Thus, by examining the mechanism of quantifier scope interpretation, we will certainly gain some insight into how these different modules interact with one another. To observe it, two experiments, an offline judgment task and an eye-tracking experiment, were conducted to investigate the interpretation of doubly quantified sentences in Chinese, like Mei-ge qiangdao dou qiang-le yi-ge yinhang (Every robber robbed a bank). According to current literature, doubly quantified sentences in Chinese like the above are unambiguous, which can only be interpreted as "for every robber x, there is a bank y, such that x robbed y"(surface scope reading), contrary to their ambiguous English counterparts, which also allow the interpretation that "there is a bank y, such that for every robber x, x robbed y"(inverse scope reading). Specifically, three questions were examined, that is, (i) What is the initial reading of doubly quantified sentences in Chinese? (ii) Whether inverse scope interpretation can be available if appropriate contexts are provided? (iii) What are the processing time courses engaged in quantifier scope interpretation? The results showed that (i) Initially, the language processor computes the surface scope representation and the inverse scope representation in parallel, thus, doubly quantified sentences in Chinese are ambiguous; (ii) The discourse information is not employed in initial processing of relative scope, it serves to evaluate the two representations in reanalysis; (iii) The lexical information of verbs affects their scope-taking patterns. We suggest that these findings provide evidence for the Modular Model, one of the major contenders in the literature on sentence processing. |
Bob McMurray; Michael K. Tanenhaus; Richard N. Aslin Within-category VOT affects recovery from "lexical" garden-paths: Evidence against phoneme-level inhibition Journal Article In: Journal of Memory and Language, vol. 60, no. 1, pp. 65–91, 2009. @article{McMurray2009, Spoken word recognition shows gradient sensitivity to within-category voice onset time (VOT), as predicted by several current models of spoken word recognition, including TRACE (McClelland, J., & Elman, J. (1986). The TRACE model of speech perception. Cognitive Psychology, 18, 1-86). It remains unclear, however, whether this sensitivity is short-lived or whether it persists over multiple syllables. VOT continua were synthesized for pairs of words like barricade and parakeet, which differ in the voicing of their initial phoneme, but otherwise overlap for at least four phonemes, creating an opportunity for "lexical garden-paths" when listeners encounter the phonemic information consistent with only one member of the pair. Simulations established that phoneme-level inhibition in TRACE eliminates sensitivity to VOT too rapidly to influence recovery. However, in two Visual World experiments, look-contingent and response-contingent analyses demonstrated effects of word initial VOT on lexical garden-path recovery. These results are inconsistent with inhibition at the phoneme level and support models of spoken word recognition in which sub-phonetic detail is preserved throughout the processing system. |
Daniele Panizza; Gennaro Chierchia; Charles Clifton On the role of entailment patterns and scalar implicatures in the processing of numerals Journal Article In: Journal of Memory and Language, vol. 61, no. 4, pp. 503–518, 2009. @article{Panizza2009, There has been much debate, in both the linguistics and the psycholinguistics literature, concerning numbers and the interpretation of number denoting determiners ('numerals'). Such debate concerns, in particular, the nature and distribution of upper-bounded ('exact') interpretations vs. lower-bounded ('at-least') construals. In the present paper we show that the interpretation and processing of numerals are affected by the entailment properties of the context in which they occur. Experiment 1 established off-line preferences using a questionnaire. Experiment 2 investigated the processing issue through an eye tracking experiment using a silent reading task. Our results show that the upper-bounded interpretation of numerals occurs more often in an upward entailing context than in a downward entailing context. Reading times of the numeral itself were longer when it was embedded in an upward entailing context than when it was not, indicating that processing resources were required when the context triggered an upper-bounded interpretation. However, reading of a following context that required an upper-bounded interpretation triggered more regressions towards the numeral when it had occurred in a downward entailing context than in an upward entailing one. Such findings show that speakers' interpretation and processing of numerals is systematically affected by the polarity of the sentence in which they occur, and support the hypothesis that the upper-bounded interpretation of numerals is due to a scalar implicature. |

In the present experiment, we examined how word discriminability affects the pattern of eye movements when reading unspaced text in an alphabetic language. More specifically, we designed an experiment in which participants read three types of sentences: normally written sentences, regular unspaced sentences, and alternatingbold unspaced sentences. Although there was a reading cost in the unspaced sentences relative to the normally written sentences, this cost was much smaller in alternatingbold unspaced sentences than in regular unspaced sentences. |
Manuel Perea; Joana Acha; Manuel Carreiras Eye movements when reading text messaging (txt msgng) Journal Article In: Quarterly Journal of Experimental Psychology, vol. 62, no. 8, pp. 1560–1567, 2009. @article{Perea2009a, The growing popularity of mobile-phone technology has led to changes in the way people–particularly younger people–communicate. A clear example of this is the advent of Short Message Service (SMS) language, which includes orthographic abbreviations (e.g., omitting vowels, as in wk, week) and phonetic respelling (e.g., using u instead of you). In the present study, we examined the pattern of eye movements during reading of SMS sentences (e.g., my hols wr gr8), relative to normally written sentences, in a sample of skilled "texters". SMS sentences were created by using (mostly) orthographic or phonological abbreviations. Results showed that there is a reading cost–both at a local level and at a global level–for individuals who are highly expert in SMS language. Furthermore, phonological abbreviations resulted in a greater cost than orthographic abbreviations. |

Mueri About the role of visual field defects in pure alexia Journal Article In: Brain, vol. 132, no. 7, pp. 1907–1917, 2009. @article{Pflugshaupt2009, Pure alexia is an acquired reading disorder characterized by a disproportionate prolongation of reading time as a function of word length. Although the vast majority of cases reported in the literature show a right-sided visual defect, little is known about the contribution of this low-level visual impairment to their reading difficulties. The present study was aimed at investigating this issue by comparing eye movement patterns during text reading in six patients with pure alexia with those of six patients with hemianopic dyslexia showing similar right-sided visual field defects. We found that the role of the field defect in the reading difficulties of pure alexics was highly deficit-specific. While the amplitude of rightward saccades during text reading seems largely determined by the restricted visual field, other visuo-motor impairments—particularly the pronounced increases in fixation frequency and viewing time as a function of word length—may have little to do with their visual field defect. In addition, subtracting the lesions of the hemianopic dyslexics from those found in pure alexics revealed the largest group differences in posterior parts of the left fusiform gyrus, occipito-temporal sulcus and inferior temporal gyrus. These regions included the coordinate assigned to the centre of the visual word form area in healthy adults, which provides further evidence for a relation between pure alexia and a damaged visual word form area. Finally, we propose a list of three criteria that may improve the differential diagnosis of pure alexia and allow appropriate therapy recommendations. |

In both of these conditions, the homographs were followed by disambiguating material that supported the subordinate meaning and ruled out the dominant meaning. Fixation times on the homograph were longer in the single-meaning condition than in the dual-meaning condition, whereas the reverse pattern was demonstrated for fixation times on the disambiguating region; these effects were observed as early as first-fixation duration. The findings strongly support the reordered access model of lexical ambiguity resolution. |
Timothy J. Slattery Word misperception, the neighbor frequency effect, and the role of sentence context: Evidence from eye movements Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 35, no. 6, pp. 1969–1975, 2009. @article{Slattery2009, An eye movement experiment was conducted to investigate whether the processing of a word can be affected by its higher frequency neighbor (HFN). Target words with an HFN (birch) or without one (spruce) were embedded into 2 types of sentence frames: 1 in which the HFN (birth) could fit given the prior sentence context, and 1 in which it could not. The results suggest that words can be misperceived as their HFN, and that top-down information from sentence context strongly modulates this effect. Implications for models of word recognition and eye movements during reading are discussed. |
Rebecca L. Johnson The quiet clam is quite calm: Transposed-letter neighborhood effects on eye movements during reading Journal Article In: Journal of Experimental Psychology: Learning, Memory, and Cognition, vol. 35, no. 4, pp. 943–969, 2009. @article{Johnson2009, In responses time tasks, inhibitory neighborhood effects have been found for word pairs that differ in a transposition of two adjacent letters (e.g., clam/calm). Here, the author describes two eye-tracking experiments conducted to explore transposed-letter (TL) neighborhood effects within the context of normal silent reading. In Experiment 1, sentences contained a target word that either has a TL neighbor (e.g., angel, which has the TL neighbor angle) or does not (e.g., alien). In Experiment 2, the context was manipulated to examine whether semantic constraints attenuate neighborhood effects. Readers took longer to process words that have a TL neighbor than control words but only when either member of the TL pair was likely. Furthermore, this interference effect occurred very late in processing and was not affected by relative word frequency. These interference effects can be explained either by the spreading of activation from the target word to its TL neighbor or by the misidentification of target words for their TL neighbors. Implications for models of orthographic input coding and models of eye-movement control are discussed. |
