Outline of Final Research Achievements

This study investigated the relationship between sense of agency and time perception. Intentional binding refers to a compression of perceived temporal interval between an action and its sensory outcome. We found that an intra-individual correlation between explicit sense of agency and intentional binding, which suggests that one can feel stronger sense of agency when stronger intentional binding occurs. We also found that intentional binding occurs not only in an action-outcome dyad but also in action-outcome alternations.

Academic Significance and Societal Importance of the Research Achievements

バインド効果が主体感の潜在指標とされながらも,それらの具体的関係は明らかでなかった。本研究は,バインド効果と主体感が,個人間というよりむしろ個人内で相関(共変)することを示唆し,過去と将来の関連研究に対して方法論的な示唆を提供する。主体感の異常が統合失調症等の精神疾患と関連することから,本研究は臨床心理学・精神医学的な研究にも基礎的知見を提供する。
