Academic Significance and Societal Importance of the Research Achievements	本研究課題では、自由意志・それと関わる心的機能・決定論をめぐる諸信念や認知（以降、自由意志関連信念・認知と呼ぶ）の社会心理学的機能を明らかにするなかで、自由意志関連信念・認知の効果をめぐる実証的知見の提供に加え、自己制御や対人認知という社会的認知のコア領域の知見を、「自由意思信念－決定論的信念」という軸により、道徳的な判断や行動という観点から統合的に再構築した。また哲学との連携により、人文的な問い（我々の自由意志の存在や行動の決定因の概念構造）を実践的な問い（自由意志がもたらす心的過程という科学的知見をどのように生かすのか）にも概念工学という立場から展開した。
