Outline of Final Research Achievements

The results of this study showed that prosociality decreased from the adolescent generation until the 20s, and then showed a trend of gradual increase with age. In addition, while pro-self individuals took longer to perform prosocial behavior, there was no association between prosocial behavior and reaction time in pro-social individuals. It was also found that those with better friendships were more likely to be classified as pro-social. These results were similar to those found in a comparison using 3 years of longitudinal data.

Academic Significance and Societal Importance of the Research Achievements

本研究は思春期世代の子どもを対象に経済ゲームを用いて向社会行動を測定し、子どもの社会環境要因が向社会行動へどのような影響を与えているかを横断・縦断的に検討した。多くの研究の場合、子どもの向社会行動は質問紙による測定がなされており、本研究のような成人の研究で用いられている経済ゲームを子どもへ適用した試みは少なく、また社会環境要因との関わりに着目した研究は少ない。それらの点において本研究は貴重なデータを提供したと考えられる。
