Outline of Research at the Start

ヒトは複雑な構造を持つ社会で生きており、日々他者との力関係を考慮しつつ協力・競合のバランスを取る必要に迫られる。この序列関係の下での行動選択を誤れば組織や家庭の中で平和に生きることは困難である。しかし、序列関係のある者どうしが協力・競合を選択する脳内プロセスは未知である。本研究ではヒトと、ヒトと同様に強固な序列関係を持ち高度な意思決定が可能なマカクザルを被験者として、支配関係のある複数被験者の協力・競合の脳内選択過程を明らかにする。

Outline of Final Research Achievements

By sandwiching a high-resolution transparent display between transparent touch panels, we constructed a social behavior experimental system that allows for touch-based action selection while viewing the identity and detailed facial expressions of the other party. We conducted an experiment under social conditions where subordinate macaques could choose between options where both their own rewards and the amount of air puffs for the superior opponent were either large or small. As a result, it was found that both macaques, despite differing frequencies, chose the prosocial option to reduce the opponent's air puffs even at the cost of their own rewards. This demonstrates clear altruistic behavior by the macaques in an experimental environment. This study was conducted in collaboration with Associate Professor Kei Watanabe of Osaka University.
