Outline of Final Research Achievements

This study has demonstrated that stimuli presented immediately after an action are more readily recalled than those merely observed. Memory enhancement was suggested not only during the execution of an action but also in the preparatory stages of the action. Additionally, actions that elicited a stimulus were found to be more memorable than actions performed subsequent to the stimulus. Alongside these findings, this research has also examined the perceptual mechanisms by which stimuli following actions are recognized as outcomes through computational models. Furthermore, I have clarified the processes through which new associations between actions and outcomes are acquired. Taken together, I provided extensive insights into the memory processing of actions and their results within the framework of this project.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた知見は行動と記憶のインタラクションの新たな側面を示すものであり，将来的に行動と記憶に関する理論の発展に貢献することが期待される。特に、従来の研究が行動と刺激の時間的近接性のみに焦点を当ててきたのに対し、本研究では先行刺激や行動結果といった行動と刺激の機能的関係から分析する枠組みが有用であることを示した。行動による記憶促進の可能性は，環境との主体的なインタラクションを重視するアクティブ・ラーニング等の教育効果についても理論的根拠を与えうる。
