| Outline of Final Research Achievements |
How do athletes achieve superior motor control in less than a second? Presentstudy focused on anticipation ability and aimed to clarify its mechanism. The main findings were that skilled athletes were able to accurately predict future outcomes from the movement of their actor (i.e., predicting the trajectory of the ball from the throwing movement), and that they experienced the observed actions as if they had performed them themselves. In addition, it was shown that the athletes did not only rely on the movement information of actors as a cue for anticipation, but also integrated other information to make anticipation.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では熟練したアスリートが，1) 他者の動きの視覚情報ではなく，他者の動きに内在する筋運動感覚情報を手掛かりとして予測していること，2) 予測において動作情報は重要であり，他の情報と信頼度に応じて重みづけ統合され利用されることを示した．これらの知見はアスリートの卓越した予測のメカニズムの理解を進展させるものである．
またこれらの知見は，予測能力を高めるためには，運動に伴う筋運動感覚とその結果の関係の学習経験が必要であること，予測手がかりとなるすべての情報を含む環境でのトレーニングが必要であることという現場に重要な知見をもたらすものと思われる．
