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 up various types of visual information during a fixation while reading. This study involved making display changes, based on eye position, in the text pattern as the subject was in the act of reading from it, and then examining the effects these changes produced on eye behavior. The results indicated… 

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

Asymmetry of the effective visual field in reading

The results of these experiments indicate that the effective visual field extends from the beginning of the currently fixated word up to about 15 characters to the right of fixation, independent of the number of letters available to the left of fixation.

The perceptual span and peripheral cues in reading

The control of saccade size and fixation duration in reading: The limits of linguistic control

It is found that low-quality cues such as word length can be extracted from this region sufficiently quickly to influence the size of the immediately following saccade.

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 cognitive psychology: On-line computer approaches to studying visual information processing

The characteristics of an on-line eye movement recording system are briefly described, followed by a description of the research using such a system to investigate reading, integration of information across eye movements, eccentric vision, and picture processing and visual search.

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.

Asymmetry of the perceptual span in reading

An on-line computer technique was used to determine whether three skilled readers acquired visual information equally far to the left and right of central vision during fixations in reading. None of

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



Identifying the Span of the Effective Stimulus in Reading. Final Report.

A computer-based Eye-Novement Controlled Display System was developed for the study of perceptual processes in reading. Stu:les were conducted to identify the region from which skilled readers pick

In reading the visual system behaves like a single-shot camera firing at not more than about five times per second, a serious criticism of reading films using windows to ‘improve’ the reading of adults.

On-line monitoring of eye-position signals in contingent and noncontingent paradigms

This paper presents a research methodology for the study of human attentional and perceptual processes by means of on-line monitoring of eye-position signals, appropriate to a variety of studies in which eye movements are considered to be part of an attentional control system.

Visual noise causes tunnel vision

Ss had quickly to detect similarities between two uppercase letters presented peripherally and one other central letter falling on the fovea. These three characters were so legible that this task was
