Parafoveal preview benefits during silent and oral reading: Testing the parafoveal information extraction hypothesis

The preview of a parafoveally visible word conveys benefits when it is subsequently fixated. The current study examined whether these benefits are determined by the effectiveness of parafoveal information extraction, as implied by current models of eye movement control during reading, or by the effectiveness with which extracted information is integrated when a previewed word is fixated. For this, the boundary technique was used to manipulate the extent to which parafoveal information could be extracted, and text was read silently or orally. Consistent with prior work, a parafoveal target word preview conveyed fewer benefits when less parafoveal information could be extracted, target viewing durations were longer during oral than during silent reading, and the two factors interacted in the target fixation data, with smaller preview benefits during oral than during silent reading. Survival analyses indicated that this occurred because parafoveal information use occurred at later point in time during oral reading. Diminished opportunity for parafoveal information extraction also diminished target skipping rate, and it resulted in smaller saccades to target words, but these effects were not influenced by reading mode. Parafoveally extracted information was thus used less effectively during oral reading only when it involved the integration of parafoveally extracted information during subsequent target viewing. The dissociation of extraction from integration challenges current models of eye movement control.     

默读和出声阅读的副中央凹预视效应

以往研究大多考察默读中是否存在副中央凹预视效应及存在何种类型的预视效应,很少有研究探讨出声阅读中的副中央凹预视效应以及阅读中预视信息提取的时间进程。本研究采用边界范式,通过两个眼动实验考察默读和出声阅读中的副中央凹预视效应及预视信息提取的时间进程。实验1发现在默读和出声阅读中都存在副中央凹预视效应,但是默读中副中央凹预视效应更大。实验2发现出声阅读中在注视中央凹词汇的早期不能提取副中央凹处信息。两个实验的结果表明默读和出声阅读条件下的副中央凹加工是不同的,需要用不同的眼动模型解释。     

The role of global top-down factors in local eye-movement control in reading

Although the development of the field of reading has been impressive, there are a number of issues that still require much more attention. One of these concerns the variability of skilled reading within the individual. This paper explores the topic in three ways: (1) it quantifies the extent to which, two factors, the specific reading task (comprehension vs. word verification) and the format of reading material (sentence vs. passage) influence the temporal aspects of reading as expressed in word-viewing durations; (2) it examines whether they also affect visuomotor aspects of eye-movement control; and (3) determine whether they can modulate local lexical processing. The results reveal reading as a dynamic, interactive process involving semi-autonomous modules, with top-down influences clearly evident in the eye-movement record.     

Theoretical perspectives on eye movements in reading: Past controversies,current issues,and an agenda for future research

The study of eye movements has become a well established and widely used methodology in experimental reading research. This Introduction provides a survey of some key methodological issues, followed by a discussion of major trends in the development of theories and models of eye movement control in fluent reading. Among the issues to be considered in future research are problems of methodology, a stronger grounding in basic research, integration with the neighbouring area of research on single word recognition, more systematic approaches to model evaluation and comparison, and more work on individual variation and effects of task demands in reading.     

Temporal overlap in the linguistic processing of successive words in reading: reply to Pollatsek, Reichle, and Rayner (2006a)

A. Pollatsek, E. D. Reichle, and K. Rayner argue that the critical findings in A. W. Inhoff, B. M. Eiter, and R. Radach are in general agreement with core assumptions of sequential attention shift models if additional assumptions and facts are considered. The current authors critically discuss the hypothesized time line of processing and indicate that the success of Pollatsek et al.'s simulation is predicated on a gross underestimation of the pretarget word's viewing duration in Inhoff et al. and that the actual data are difficult to reconcile with the strictly serial attention shift assumption. The authors also discuss attention shifting and saccade programming assumptions in the E-Z Reader model and conclude that these are not in harmony with research in related domains of study.     

Orthographic regularity gradually modulates saccade amplitudes in reading

The present research tested the hypothesis that variations in the orthographic regularity of word beginnings influence landing positions and amplitudes of interword saccades in continuous reading. Participants were asked to read sentences including target words of low, medium, and high frequency of initial quadrigrams that were either single‐root nouns or noun‐noun compounds. Saccades landed further into words with more regular beginnings, irrespective of whether the target was a compound word or not. Critically, the orthographic landing site effect was graded, suggesting that orthographic information continuously modulates saccade amplitude before and after the decision to move has been made.     

Phonological representation of words in working memory during sentence reading

The temporal dynamics of a visual target word’s phonological representation was examined by presentation of an irrelevant spoken companion word when the participant’s eyes reached the target’s location during sentence reading. The spoken word was identical, similar, or dissimilar to the phonological specification of the visual target. All spoken words increased the time spent viewing the target, with larger effects in thesimilar anddissimilar spoken word conditions than in theidentical condition. The reading of posttarget text was disrupted when the spoken word was similar but not when it was identical or dissimilar to the target. Phonological interference indicates that a word’s phonological representation remains active after it has been identified during sentence reading.     

Exterior letters are not privileged in the early stage of visual word recognition during reading: comment on Jordan, Thomas, Patching and Scott-Brown (2003)

Potential sources for the discrepancy between the letter position effects in T. R. Jordan, S. M. Thomas, G. R. Patching, and K. C. Scott-Brown's (2003; see record 2003-07955-013) and D. Briihl and A. W. Inhoff s (1995; see record 1995-20036-001) studies are examined. The authors conclude that the lack of control over where useful information is acquired during reading in Jordan et al.'s study, rather than differences in the orthographic consistency and the availability of word shape information, account for the discrepant effect pattern in the 2 studies. The processing of a word during reading begins before it is fixated, when beginning letters occupy a particularly favorable parafoveal location that is independent of word length. Knowledge of parafoveal word length cannot be used to selectively process exterior letters during the initial phase of visual word recognition.     

Use of colour for language processing during reading

The study examined whether literal correspondence is necessary for the use of visual features during word recognition and text comprehension. Eye movements were recorded during reading and used to change the colour of dialogue when it was fixated. In symbolically congruent colour conditions, dialogue of female and male characters was shown in orchid and blue, respectively. The reversed assignment was used in incongruent conditions, and no colouring was applied in a control condition. Analyses of oculomotor activity revealed Stroop-type congruency effects during dialogue reading, with shorter viewing durations in congruent than incongruent conditions. Colour influenced oculomotor measures that index the recognition and integration of words, indicating that it influenced multiple stages of language processing.     

A contingent speech technique in eye movement research on reading

A novel eye-movement-contingent method is presented. It builds on and extends established eye-movement-contingent visual display change methods in that it uses movements of the eyes to control the presentation of acoustic information during sentence reading. In one implementation, an irrelevant spoken word is presented when the eyes cross a predetermined spatial boundary before they move on to a selected visual target word. The relationship between the spoken word and the visual target is manipulated, and the pattern of interference, caused by the presentation of the spoken word, is used to determine the nature and time course of activated representations. Results from three recently completed experiments in which the technique was used show that a word’s phonological code remains active after it has been read and that the activated code has speech-like properties.
