Two experiments were conducted to examine the effects of foveal processing difficulty on the perceptual span in reading. Subjects read sentences while their eye movements were recorded. By changing the text contingent on the reader's current point of fixation, foveal processing difficulty and the availability of parafoveal word information were independently manipulated. In Experiment 1, foveal processing difficulty was manipulated by lexical frequency, and in Experiment 2 foveal difficulty was…

Eye movements and the modulation of parafoveal processing by foveal processing difficulty: A reexamination

Foveal load modulated preview benefit for participants who were not aware of the display changes during reading and regardless of fixation durations on the foveal word, consistent with Henderson and Ferreira (1990).

Lexical Quality and Eye Movements: Individual Differences in the Perceptual Span of Skilled Adult Readers

Results suggest that, in addition to supporting rapid lexical retrieval of fixated words, the high quality lexical representations indexed by the combination of high reading and spelling ability support efficient processing of parafoveal information and effective saccadic targeting.

Eye movement control during reading: fixation measures reflect foveal but not parafoveal processing difficulty.

The data reported here show that neither the frequency nor the combined length, frequency and class of the upcoming word affect eye movement behaviour on the current word, which support the sequential attention--parallel programming model of eye movement control in reading.

Out of the corner of my eye: Foveal semantic load modulates parafoveal processing in reading.

It is suggested that sentential context modulates the allocation of attention in the parafovea, such that covert allocation of Attention to parafovesal processing is disrupted when foveal words are inconsistent with expectations based on various contextual constraints.

Reading strategy modulates parafoveal-on-foveal effects in sentence reading

It is demonstrated that increasing the fixation probability on function words with a manipulation of the expected difficulty and frequency of questions reduces an age difference in skipping probability and helps to uncover significant parafoveal-on-foveal effects in this group of old adults.

Individual differences in the perceptual span during reading: Evidence from the moving window technique

The size of readers’ perceptual span was modulated byindividual differences in language ability but not by individual differences in oculomotor processing speed, suggesting that readers with greater language proficiency are more likely to have efficient mechanisms to extract linguistic information beyond the fixated word.

Parafoveal processing affects outgoing saccade length during the reading of Chinese.

The results of this study indicate that preview availability and its interaction with word frequency modulated the length of the saccades exiting the target words, suggesting important functional roles for parafoveal processing in determining where the eyes move during reading.

Cognitive control of eye movements in reading and visual search: Evidence from frequency-based effects

Experiments in this dissertation investigate the role of cognition in eye-movement behavior during scanning and reading. Shorter and fewer fixations on the more frequent and predictable words have



The span of the effective stimulus during a fixation in reading

A computer-based eye-movement controlled, display system was developed for the study of perceptual processes in reading. A study was conducted to identify the region from which skilled readers pick

On the Role and Control of Eye Movements in Reading

Three issues concerning reading are considered the integration of visual information across fixations, the asymmetry of the perceptual span, and the control of eye movements. A model of eye movement

Masking of foveal and parafoveal vision during eye fixations in reading.

The results of the experiments point out the relative importance of foveal and parafoveal vision for reading and indicate that most of the visual information necessary for reading can be acquired during the first 50 msec that information is available during an eye fixation.

Inferences about eye movement control from the perceptual span in reading

Subjects’ eye fixations in a target region were examined as a function of how far the eye was from the beginning of a target word on the previous fixation, and the results indicated that the decision to adjust the length of a saccade can be made after the decisions to move the eye.

Perceptual span for letter distinctions during reading

THIS STUDY investigated the size of the visual region within which adults use visual information to distinguish among letters as they read. Fifteen college students read passages from a cathode-ray

Eye movements and integrating information across fixations.

The results indicated that the types of prior parafoveal information studied facilitated the naming of the word.

Eye Movements and the Perceptual Span in Reading.

A DISPLAY SYSTEM CONTROLLED by the eye movements of the reader was used to identify the area in a text from which information is collected during a fixation in silent reading. As the validity of the
