価値・予測・誤差─社会性を支える意思決定システム─

抄録

Though brain regions which are related to social behaviors and social affects have been widely elucidated, the mechanisms how those regions determine social mind are not understood. Here I suggest that a theoretical framework inspired by research on decision-making and reinforcement learning might be useful to consider the mechanisms underlying human’s social mind. Specifically, it has been argued that three systems of decision-making, the Pavlovian system, goal-directed system, and habit system interact, based on evaluation of values, to determine wide ranges of behaviors of humans and animals. The present article proposes that such framework can be expanded to social behaviors and social affect, to shed new lights on interpretations of significance of the social phenomena and to draw new hypotheses for future empirical studies.
