Outline of Final Research Achievements

Previous studies have examined the effects of different pictures of tools on manipulation, and methods of presenting different pictures of tools on Action RT before initiating imitation activities. However, the effects of holding a tool in hand on imitation have not been directly examined to date. Therefore, adult participants of an experiment were requested to imitate the action of grasping a cup placed in front of them with their hand or imitate the action of grasping the cup with a tool held in their hand after watching an action picture. The results indicated that Action RT between presenting an action picture and performing an imitation was shorter when holding a tool in hand compared to when not holding a tool. There were no differences in Action RT when the effector was shown as a hand and when the effector was shown as a tool.

Academic Significance and Societal Importance of the Research Achievements

模倣は自他の身体の変換を伴う。現在新型コロナウイルスの影響によって，ITによる遠隔が多様されるようになった。利便性の高さは充分に評価できる。しかしながら，身体と身体が無意識に影響を及ぼし合うこと，視覚と聴覚以外の感覚の役割，いわゆるコミュニケーションのトランシーバーモデルでは伝達できない事項等，模倣の実験を通して身体の重要性を改めて認識できた。今後の社会生活に活かしていける有意義な知見である。
