Provides a personal account of the development of the Eye Movement Contingent Display Control research methodology for the study of perceptual and cognitive processes in reading. Suggests that the usefulness of eye movement techniques for studying human cognition is still in its beginning stages. (RS)

To examine the nature of forward saccadic eye movements in reading, eye movement records were collected from college students as they read a short passage. Forward saccades from this data set were analyzed to determine factors influencing the likelihood of any given letter in the text being the recipient of the next fixation. Data indicated that…

Eye movement monitoring is useful both in the control of experiments on reading and as a source of data. Experiments using eye monitoring techniques have helped develop the following conclusions about the reading process: the region of text read during a fixation is quite small and asymmetric to the right of the center of vision, successive…

Results from studies of language identification in noise and of word identification from tachistoscopic presentation clearly indicate that contextual information can be used to facilitate word identification under inadequate stimulus conditions. But these results do not provide strong evidence that such an interaction is occurring during normal…

Three problems in the use of eye movement data for the study of language processing are discussed in this report: the perceptual span problem, the data summary problem, and the eye-mind lag problem. Recent research on perception during reading that bears on these problems is also described. Finally, a general approach to the use of eye movement…

This report argues that the Mean Gaze Durations or eye movement records used by M. A. Just and P. A. Carpenter to develop a model of reading comprehension are an inappropriate measure of processing time. An alternative approach called Read to Right of Gaze (RRG-1), which assumes that more than one word can be read during a fixation, is recommended…

The research reviewed in this paper concerns the visual perceptual processes occurring as people are engaged in the act of reading. The issues that are examined include the control of eye movements, perception during a fixation, and perception across successive fixations. Consideration also is given to problems related to obtaining information…

A computer-based Eye-Movement Controlled Display System was developed for the study of perceptual processes in reading. Studies were conducted to identify the region from which skilled readers pick up various types of visual information during a fixation while reading. The results indicated that the subjects acquired word length pattern…

To investigate the relationship between the location of the words being read and the location of the eyes in the text, three experiments were conducted using the Disappearing Text Technique with college students. This was done by occasionally removing the text during reading and having the reader report the last word that had been read.…

Greater understanding of reading can come about only after more basic reading research has been accomplished. Basic research should focus on what constitutes good reading, which means that the type of research that will identify characteristics of good reading must be a detailed assessment of variable effects on reading behaviors (not whether…

While most present research suggests that visual information acquired from peripheral visual areas on one fixation during reading facilitates the identification of words available on the next fixation, some researchers hold with the "word unit hypothesis," which suggests that information gained peripherally from a word on one fixation…

In the study of perception during reading, the use of eye movement contingent control of the stimulus display has proved to be a useful research technique. With such a system, it is possible to experimentally manipulate, in real time, the characteristics of the stimulus display that is present on selected fixations as reading is in progress and to…

The application of computer technology to reading research has made it possible to study the perceptual processes that take place as people read with a level of precision never before attainable. This computer assisted research has revealed that where the eyes go for fixations is of significance to normal reading and that during each fixation only…

Research involving eye movement monitoring can help in understanding the nature of the mental processes involved in reading, how these develop as one learns to read, and what processing strategies or characteristics are more common in those children who fail to show normal progress in learning to read. First, eye movement records show that the…
