Outline of Final Research Achievements

When cooperating for a common goal, humans need to predict the actions of others in order to coordinate their own movements. The joint Simon task is used to examine the degree to which we share the action representations of others. The purpose of this study was to clarify the cognition of others in cooperative behavior in a non-human species. We performed a joint Simon task on rats to examine whether they shared the other's stimulus-response mapping representations. The results confirmed the joint Simon effect in rats. In rats with high prosociality and reported cooperative behavior, it was shown that they may perform joint actions by including others' actions in their own action planning.

Academic Significance and Societal Importance of the Research Achievements

この研究では、ヒト以外の霊長類以外では初めて、共同サイモン効果を検討した。これまでにも協力行動といった共同行為が、ヒト以外のいくつかの種において報告されてきたが、これまでには協力行動が成立する条件に注目されることが多かった。この研究では、共同行為における社会認知に着目し、共同行為を支える認知基盤を検討した。ほかの系統の種においても同様の検討を行うことで、他者との共同運動主体感の進化、メカニズムの理解が深まるだろう。
