Outline of Final Research Achievements

This study focused on social mindfulness, a prosocial decision-making in which individuals voluntarily suppress their own needs in order to maximize the choices of others. To examine cultural differences in social mindfulness and its psychological mechanisms, we conducted a secondary analysis of large sample data obtained in Japan and a cross-cultural study between Japan and North America. Results showed that SoMi was higher in Japan compared to North America. Moreover, SoMi was associated with empathy, particularly perspective-taking, in both Japan and North America. However, the association between SoMi and perspective-taking showed different patterns in Japan and North America. In North America, perspective-taking and SoMi showed an inverted U-shaped association, whereas in Japan they showed a U-shaped association.

Academic Significance and Societal Importance of the Research Achievements

本研究では、向社会的意思決定であるsocial mindfulness (SoMi) に文化差があること、またSoMiの背後にある心理メカニズムが文化によって異なる可能性が示唆された。特に、共感性がSoMiと関連することは日本と北米で一貫していたものの、共感性とSoMiのパターンは文化によって異なることが示された。このことは、外的には同じ行動であっても文化によって異なる心理基盤に基づいている可能性、また同じ心理であっても文化によっては行動に対して異なる影響を与える可能性を示唆するものであり、人間の複雑な行動を理解する上で文化的影響を考慮することの重要性を示すものと言える。
