Analysis of The Timing of Blink Based on Identification Task Using Sequential Growing Figures

Abstract

This paper analyzes changes in the timing of a spontaneous blink by altering the time of a figure offset at different several points during a figure identification task, which is based on a time-varying image presentation technique. To compare with the conventional discrete trial task, additional task is also designed. In this task, a still image which is presented at immediately before a figure offset in the former task is presented to a subject in a brief exposure duration. We found that concentrated blinks occurring after a figure offset in either of the tasks is concerned with the factor of stimulus offset. Although there is a relation between blink latency and the task difficulty, we cannot conclude that a blink tends to occur just after the termination of the identification processing.
