Do So

We are largely in agreement with the Findlay & Walker model. However, they appear to dismiss the role of covert spatial attention in tasks in which people are free to move their eyes. We argue that an account of the facts about the perceptual span in reading requires a window of attention not centered around the fovea. Moreover, a computational model of reading that we (Reichle et al. 1998) developed gives a good account of eye movement control in reading and would be unable to do so without relying heavily on covert attention.

Strategy Making

Eye-movement studies have demonstrated that, relative to college-aged readers, older readers of alphabetic languages like English and German tend to read more slowly, making more frequent and longer fixations and longer saccades, and skipping more words, but also making more frequent regressions. These findings have led to suggestions that older readers either adopt a “risky” strategy of using context to “guess” words as a way of compensating for slower rates of lexical processing, or have a smaller and more asymmetrical perceptual span. Unfortunately, neither of these hypotheses seemingly explains more recent observations that older readers of Chinese seem to adopt a more “conservative” strategy, making shorter saccades and skipping less often. In this paper, we use the E-Z Reader model of eye-movement control to examine several possible accounts of the differences between college-aged and older readers of both alphabetic and non-alphabetic languages. These simulations re-confirm that the “risky” strategy may be sufficient to explain age-related differences in reader’s eye movements, with older readers of English versus Chinese being, respectively, more versus less inclined to guess upcoming words. The implications of these results for aging, reading, and models of eye-movement control are discussed.

The anatomical connection between the frontal eye field and the cerebellar hemispheric lobule VII (H-VII) suggests a potential role of the hemisphere in voluntary eye movement control. To reveal the involvement of the hemisphere in smooth pursuit and saccade control, we made a unilateral lesion around H-VII and examined its effects in three Macaca fuscata that were trained to pursue visually a small target. To the step (3°)-ramp (5–20°/s) target motion, the monkeys usually showed an initial pursuit eye movement at a latency of 80–140 ms and a small catch-up saccade at 140–220 ms that was followed by a postsaccadic pursuit eye movement that roughly matched the ramp target velocity. After unilateral cerebellar hemispheric lesioning, the initial pursuit eye movements were impaired, and the velocities of the postsaccadic pursuit eye movements decreased. The onsets of 5° visually guided saccades to the stationary target were delayed, and their amplitudes showed a tendency of increased trial-to-trial variability but never became hypo- or hypermetric. Similar tendencies were observed in the onsets and amplitudes of catch-up saccades. The adaptation of open-loop smooth pursuit velocity, tested by a step increase in target velocity for a brief period, was impaired. These lesion effects were recognized in all directions, particularly in the ipsiversive direction. A recovery was observed at 4 wk postlesion for some of these lesion effects. These results suggest that the cerebellar hemispheric region around lobule VII is involved in the control of smooth pursuit and saccadic eye movements.
