Outline of Final Research Achievements |
It is one of the most important frontiers in neuroscience that is to elucidate neural functions for human social intelligence. Neural computation and information processing of other individuals, and thereby using them for one’s own decision-making, is indispensable for the social intelligence. This study addressed this issue. First, we found basic neural computations and circuits for converting information of expected reward for other individuals into one’s own decision-making (Fukuda, Ma et al,2019). Furthermore, we found different socio-behavioral phenotypes utilized the basic computations and circuits differently. Second, we also investigated how humans generate better decisions by predicting others’ decisions and their neural computations. We reported our findings on several conferences and expect to report them in details for a journal in future.

Academic Significance and Societal Importance of the Research Achievements |
他人の考えや行動を勘案した意思決定を行うことは社会知性の根幹の脳機能である。この機能の解明は、私たち一人一人がいかに社会を認識し、その中で社会知性をいかに働かせるのかといったような、人間の様々な社会制度の土台を明らかにする。またロボットや人工知能に社会性をもたせるための基盤技術の開発にも貢献する。本研究はこの脳機能の解明に迫るために、「自らが得られる報酬のみならず、他者が得られる報酬を鑑みて、行動を選択するための脳機能」および「他者の行動選択を予測して、それを生かして自らの行動を選択するための脳機能」について、その基本的な脳の情報処理と神経回路の関係を明らかにした。
