Models of eye guidance in reading rely on the concept of the perceptual span—the amount of information perceived during a single eye fixation, which is considered to be a consequence of visual and attentional constraints. To directly investigate attentional mechanisms underlying the perceptual span, we implemented a new reading paradigm—parafoveal magnification (PM)—that compensates for how visual acuity drops off as a function of retinal eccentricity. On each fixation and in real time…

Perceptual span, visual span, and visual attention span: Three potential ways to quantify limits on visual processing during reading

The primary goal of the present review is to re-specify these three concepts in terms of what they correspond to and how they are determined, and whether these three spans refer to vision-related measurements and/or are based on general cognitive abilities.

Lateralization of posterior alpha EEG reflects the distribution of spatial attention during saccadic reading.

The use of EEG alpha-band oscillations to investigate the spatial distribution of attention during reading indicates that alpha lateralization can serve as a measure of attention deployment and its link to oculomotor behavior in reading.

Microsaccades during reading

Analysis of how microsaccades shift gaze relative to the text suggests that these movements serve two important functions: a corrective function by moving the gaze regressively within longer words when the preceding saccade lands too far toward the end of these words, and an exploratory function by shifting the gaze on adjacent words to gain additional information before the execution of the next saccades.

Visual Exploration Area in Neglect: A New Analysis Method for Video-Oculography Data Based on Foveal Vision

A new complementary method to analyze FVE data based on foveal vision allows to accurately measure the portion of the picture that was effectively explored, disentangle single from overlapping fixations, and distinguish between capture and re-capture fixations.

Font size modulates saccade-target selection in Chinese reading

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

Perceptual span in individuals with aphasia

Individuals with aphasia have a smaller perceptual span than controls, which likely reflects increased effort during reading comprehension.

The Perceptual Span in Second Language Reading: An Eye-tracking Study Using a Gaze-contingent Moving Window Paradigm

The perceptual span, which is the visual area providing useful information to a reader during eye fixation, has been well investigated among native or first language (L1) readers, but not among

The gaze-contingent moving window in reading: Development and review

The development of the gaze-contingent moving window paradigm (McConkie & Rayner, 1975, 1976) is discussed and the results of the earliest research are reviewed. The original work suggested that the



Parafoveal-on-foveal effects are not an artifact of mislocated saccades

Oculomotor error leads to a proportion of saccades during reading missing the intended target. In this paper two kinds of mislocation are identified: either a word is erroneously refixated, or a word

Parafoveal-on-foveal effects in normal reading

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

Mislocated fixations can account for parafoveal-on-foveal effects in eye movements during reading

A limited parafoveal-on-foveal effect was observed: There were inflated fixation times on wordn when the preview of wordn + 1 was orthographically illegal, and this effect was associated with relatively long prior saccades.

The perceptual span and peripheral cues in reading

The spatial scale of attention strongly modulates saccade latencies.

It is argued that the spatial scale of attention determines the urgency of saccade motor preparation processes by changing the rate and rate variability of the underlying decision signal, to defer the cost of sarcades that result in little visual benefit.

Eye movement control in reading: a comparison of two types of models.

In this study, fixation duration on low-and high-frequency target words was examined as a function of fixation location and the number of fixations on a target word and the data are inconsistent with an oculomotor model.

A model with direct control and parallel programming of saccades is proposed to explain the data and eye movements in reading in general and indicates that fixation duration is under direct control.
