Outline of Final Research Achievements

This study investigated the sense of agency, time perception, and recognition memory through behavioral experiments. Intentional binding is characterized by the subjective compression of the time interval between an action and its outcome. Using statistical causal inference methods, we demonstrated a causal relationship between the sense of agency and intentional binding. In a subsequent study, we found no relationship between the sense of agency and recognition memory. Lastly, our results suggest that the order in which the action and stimulus occur may offer a better explanation for recognition memory than the distinction between motor preparation and execution.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は，時間知覚や自伝的記憶といった認知機能の理解，ならびに身体運動に生じる自己感と概念的な自己観およびこれら2つの自己の関連の理解に貢献する。また，主体感の異常と関わる統合失調症や強迫性障害などの精神疾患を理解し，介入法開発の基礎的知見を提供するという意義もある。
