Outline of Research at the Start

ヒトは,目の前にある物体を実際に手で触れることなく,その物体をイメージ(表象)し,その物体のイメージを心的に操作することで,実際にその物体を動かした後の位置や状態などを予測することができる。この心的表象操作と呼ばれる高度な能力によって,新奇な場面でも効率的な目標達成が可能となる。本研究では,同一の道具使用課題を用いて,鳥類(オカメインコ)や齧歯類(デグー),霊長類(フサオマキザル,リスザル)といった広範な種比較を行うことで,体系的な系統発生研究を進め,心的表象操作の進化過程を解明する。

Outline of Final Research Achievements

The present study showed that common squirrel monkeys, one species of New World monkey, unlike rodent rats, tend to select more options that appear to have nothing behind the food in a tool-use task. This finding was presented at the 82nd Annual Meeting of The Japanese Society for Animal Psychology. The results of studies on the manipulation of mental representations in rats were reported in a total of four papers. In addition, I reviewed tool use in nonhuman animals, and summarized my studies on tool use behavior in rats, and wrote a chapter in an international handbook on comparative psychology.

Academic Significance and Societal Importance of the Research Achievements

リスザルを対象に道具使用行動について検証した研究は国内外でも稀であり,齧歯類と同様の課題を用いて齧歯類との直接的な比較を行ったのは本研究が初となる。今後は,他の霊長類や鳥類などといったより広範な種に対して同様の課題を実施することで,心的表象操作のより緻密な進化過程が解明されることが期待される。更に,本研究のような,動物の基本的な認知能力を検証する研究は,ヒトとヒト以外の動物が共生する社会の構築に貢献し得るという波及効果も期待される。
