Abstract

The purpose of this paper is to examine the sensitivity and features of peripheral vision and fixation in smooth pursuit when visual tasks were presented on a foveal vision. The spatial range and dynamic features of peripheral vision were investigated compared to reaction time, both when the gaze of subjects were fixed and when the instruction was given to follow the moving target. As the results, reaction time was increased under both conditions when the tasks were presented to foveal vision. In addition, the sensitive area of vision tended to shift to moving direction of gaze according to velocity of the moving target. These results suggested that visual information process may be disturbed when the attention of a subject is focused to fovea, and there may be different mechanism of processing in foveal and peripheral vision.
