Outline of Final Research Achievements

Observational learning in primates (Japanese macaques) can establish avoidance of a dangerous object associated with aposematic coloration, through a fear response against a red and black color pattern. Amphibians and fishes, similar to macaques, innately showed fear responses against a red and black color pattern or red color stimuli. This cognitive predispositions contribute to not only observational learnings but also individual learnings (non-associative and associative learnings).

Academic Significance and Societal Importance of the Research Achievements

ヒトは赤色に対して恐怖情動を想起することが知られている.また,経験的に,赤色を恐怖や危険と関連した広告や信号として利用してきた.本研究は,こうした赤色に対する情動バイアスが両生類や魚類においても存在することを示唆し,ヒト心理特性の起源について重要な知見を投げかけた.また,このバイアスは,ヒトだけでなく,ヒト以外の霊長類から魚類において,恐怖や危険と関連する様々な学習を促進することを示唆した.
