Outline of Final Research Achievements

(1) In a temporal reproduction task in which the participants reproduced the duration of a given standard stimulus by pressing a push button, there were individual differences both of precision and accuracy of reproduced duration. (2) Inhibition of neural activity in the right posterior parietal cortex led enhanced performance of temporal discrimination task. (3) Change in a specific component of event related potential could be appeared when temporal interval of sound stimuli was altered abruptly.

Academic Significance and Societal Importance of the Research Achievements

本研究は、ヒトのさまざまな行動の基盤となる認知能力のひとつである時間知覚に関するメカニズムの一端を明らかにしたものであり、脳科学における新しい知見を提供するものとして学術的意義は大きい。さらに、ヒトの時間知覚の評価方法における問題点を実験データによって確認し、脳波を用いた客観的評価方法の可能性を見出したことも、今後のヒトの認知科学研究の発展に寄与することが期待される。
