  • Emergence of Equal Cooperation Induced by Characteristics of Adolescence than Adulthood in an Interrole Conflict Game among Reinforcement Learning Agents

    Abstract: People usually belong to multiple groups, and in such situations “interrole conflicts”occur. Studies on interrole conflicts have mainly targeted subjects after adulthood, although they do not occur only after the developmental stage of adulthood. In addition, limited studies have been conducted on interrole conflicts during adolescence. Furthermore, simulation studies about interrole conflicts have rarely been conducted. The purpose of this study is to clarify the difference between adolescence and adulthood in how to deal with interrole conflict situations. We propose an interrole conflict game (ICG) as a new game-theoretic framework to deal with interrole conflicts and adopt reinforcement learning agents with characteristics of adolescence or adulthood as players. Our multi-agent simulation (MAS) experiment results suggest high learning rate and low discount rate that cause typical adolescent characteristics including risk-taking, impulsivity and novelty seeking can be played important roles to cope an interrole conflict and for emergence of equal cooperation among adolescents in the interrole conflict situation.
