交互視線移動におけるサッカード発生間隔と動特性の検討

抄録

In the dark, the subjects repeatedly and alternately made saccades between the two horizontally arranged visual targets or their correspondingly remembered targets. Moreover, the intention while the subjects made gaze-shifts between the two points was changed by instruction, i.e., accurately or quickly. The results suggested the following matters. 1. The peak velocity of the saccades elicited toward the visual targets is larger than that toward the remembered targets. 2. The peak velocity of saccade changed when the subjects intended to make gaze-shifts as quickly or accurately as possible. However, the tendency of this change was different between the subjects.
