Outline of Final Research Achievements

The purpose of this study was to examine the effects of aggressive scripts on aggressive behavior. The results showed that, in Study 1, implicit attitudes toward aggression did not predict aggressive behavior. Based on these results, in Study 2, the stimuli were reexamined, and it was suggested that the lower the negativity of the aggression concept, the more likely the participants were to engage in aggressive behavior. In Study 3, the measurement method of aggressive behavior was changed and reexamined, and it was suggested that the more negative the concept of aggression was, the more likely the participants were to engage in aggressive behavior when provoked. Study 4 showed that suppression of aggressive thoughts leads to activation of the aggressive script, which in turn promotes aggressive behavior. The results of this study, which are not always consistent, should continue to be examined in the future.

Academic Significance and Societal Importance of the Research Achievements

本研究では，攻撃への潜在的態度が攻撃行動を予測する可能性を有していることを示した。また，攻撃的思考を抑制し，攻撃スクリプトを活性化させることが，攻撃行動を増強することを明らかにした。すなわち，攻撃行動の発現に我々が必ずしも意識しない攻撃スクリプトが関与する可能性が，一部支持された。これらの結果は，既存の攻撃研究に新たな知見を加える点で学術的意義がある。また，本研究の知見は，例えば，潜在的加害者の予防的・教育的介入を考える上での足掛かりになる点で社会的意義がある。ただし，本研究の知見は必ずしも一貫しない部分もあり，攻撃スクリプトが攻撃行動に及ぼす影響は今後の一層の検討が求められる。
