Research Abstract	The purpose of this study was to obtain the fundamental data of eye movement-of normal adults, children, and brain-damaged patients in various visual perceptual and cognitive tasks, and to clarify the functions of eye movement in visual perceptual and cognitive processes. The following results were found : (1) The eye movements of normal children and adults observing a target of some cartoon characters which moved sinusoidally or rectangularlly on screen was measured by EOG. Five- and six-year old subjects showed anticipatory phase of eye movements, but four-year old subjects and adults subjects didn't show such a tendency. (2) The experiments of corneal reflection method by "Talk-Eye"revealed that (i) specific differeces of the characteristics of eye movement were happened, depending on task demands for subjects observing stimulus figures, although individual differences were remarkable. (ii) when subjects could recognize "figureness" in a particular stimulus configuration, their eye movement was held within a fixed range. (3) The eye movements of a brain-damaged child showe d no differences in target features. The above-mentioned results suggest that the functions of eye movement in visual perceptual and cognitive processes should be analyzed in connections to (i) physical characteristics of stimulus as well as (ii) understanding ways of the stimulus of the perceiver.
