Outline of Final Research Achievements

We conducted studies focusing on the human tendency in information processing to "find 'minds' in external phenomena," as observed in various forms of animism across cultures. Through behavioral experiments involving infants, children, and adults, complemented by validation using mathematical models, we investigated the psychological traits that facilitate this phenomenon. Specifically, our research centered on the crucial human trait of "cooperation," examining (1) the development of strategies for selecting cooperative partners, (2) the development of resource distribution based on the partners' individual circumstances and histories, and (3) the theoretical conditions under which cooperation emerges. Additionally, we explored theoretical frameworks concerning human information processing characteristics and proposed the "psychologization of information" hypothesis, which offers new insights into the developmental and evolutionary origins of the concept of "mind."

Academic Significance and Societal Importance of the Research Achievements

誰かとかかわりを持つ際に、我々は相手の「こころ」を読もうとし、自分自身の「こころ」を探ろうとする。「こころ」は目に見えないにもかかわらず、わたしたちのコミュニケーションの「前提」となっている。本研究は「協力」を手掛かりにして「こころ」を想定する傾向の起源を探った。行動実験を通した発達研究と、数理的な解析に基づいた協力の成立条件の解析を通して、他者に対する評価方略とその発達に関するあらたな知見を提示するとともに、協力の一形態である「教える」や基盤となる思考に関する理論的な解析も進めることができた。
