Outline of Final Research Achievements

Perceptual durations can be affected by internal and external factors and often perceived as being unequal, even if the durations are physically equal to each other. In present research, the psychophysical methods were used to investigate how the perceptions of operations, self-motion and stimulus changes affect perceived presentation durations, mainly for the duration within one second. The results of the experiments suggest that perceiving operations and self-motion, as well as perceiving changes in stimuli, can lengthen the perceptual presentation duration, compared to the presentation duration without changes.

Academic Significance and Societal Importance of the Research Achievements

操作を認知することや自己運動を知覚することと外的変化が結びついたときに時間知覚に影響するのかどうかについて着目し体系的に調べた研究はこれまでになく学術的な意義があると考える。変化を認知したり、操作感や自己運動を認知することが、主観的な時間長を長くさせるという知見は、時間の感じとり方をコントロールしたいという人間の素朴な欲求に対して解決方法の一つを示していると考えられる。
