Reading without a fovea.

A visual mask moving in synchrony with the eye obliterated foveal vision during reading under certain conditions. When foveal vision was masked, reading became difficult. In another condition, a window of readable text moved in synchrony with the eye, and parafoveal vision was masked on each fixation. The results point out the importance of foveal and parafoveal vision in reading.

Eye guidance in reading: fixation locations within words.

Three broad categories of models of eye movement guidance in reading are described. According to one category, eye movements in reading are not under stimulus or cognitive control; the other two categories indicate that cognitive activities or stimulus characteristics are involved in eye guidance. In this study a number of descriptive analyses of eye movements in reading were carried out. These analyses dealt with fixation locations on letters within words of various lengths, conditional probabilities that a word will be fixed given that a prior word was or was not fixated, and average saccade length as a function of the length of the word to the right of the fixated word. The results of these analyses were supportive of models which suggest that determining where to look next while reading is made on a nonrandom basis.

Eye movements and integrating information across fixations.

A series of experiments was conducted in which a word or letter string initially appeared in parafoveal vision, followed by the subject's eye movement to the stimulus. During the saccade, the initially displayed stimulus was replaced by a word that the subject was asked to read. The results indicated that the types of prior parafoveal information studied facilitated the naming of the word. The effect was obtained when the subject made an eye movement and when the saccade was simulated. There was also evidence that attentional allocation was tied to the direction of the eye movement.

Eye movements and anaphor resolution: effects of antecedent typicality and distance.

The coordination of the eye movement control system with comprehension processes was studied. Eye movements were monitored while subjects read paragraphs containing an anaphoric noun phrase. In Experiment 1, fixations on the anaphoric noun were shorter when its antecedent was close and typical of the noun category than when it was distant and/or atypical. Subjects took longer reading the words following the anaphoric noun when the antecedent was atypical than when it was typical. In Experiment 2, distance of antecedent affected anaphor fixation times for category name anaphors but not for general noun anaphors (e.g., "object"). The results suggest that the eyes do not wait for the completion of anaphor resolution processes. Rather, these processes are completed after the eyes have left the anaphoric noun. The different patterns of effects on the anaphors themselves and the post-anaphor region were interpreted to reflect two different stages in anaphor resolution.
