| Abstract: | The purpose of this study was to verify the ability to perceive the motion of others from the viewpoint of motor control. We selected a ball-throwing task because it is one of the most skilled multi-joint movements and requires excellent coordination among the joints, and even though it is commonly observed in various sports. The stimulus was a stick picture movie featuring two movements?the normal throwing motion of a skilled thrower (model motion) and an altered throwing motion (delayed motion) developed by systematically manipulating the timing of the elbow extension. Ten highly skilled players volunteered to take part in the study. First, they observed the stimulus twice. Next, they threw the ball once using their usual throwing motion (usual throwing condition) and performed a ball-throwing task that reflected the difference between the model motion and the delayed motion (changed throwing condition). They alternately performed these trials three times. As compared to the usual throwing condition, the changed throwing condition showed a significant decrease in the temporal phase difference between the extension angular velocity at the elbow and the wrist (p < 0.05). This change corresponded to the difference between the model motion and the delayed motion in the stimulus. The result of our experiment clearly shows that the participants detected the difference between the model motion and the delayed motion and controlled their movement. | | 本研究の目的は，他者運動認知能力を自己運動制御の観点から検証することであった．実験は様々なスポーツにおいて一般的な運動であるが，関節間の卓越した協調を要する最も熟練した多関節運動の一つである投球動作を用いた．観察映像は，2つの動作－熟練者の標準投球動作（モデル動作）とモデル動作を基に肘関節と手関節の伸展のタイミングを段階的に操作した投球動作（遅延動作）－によるスティックピクチャー映像であった．運動技術レベルの高い10人が実験に参加した．まず，彼らは映像を2度観察した．次に，通常の投球（通常投球条件）と，モデル動作と遅延動作の差異を反映した投球（変化投球条件）を行った．彼らは，交互に3球ずつこれらの試技を実施した．その結果，肘関節と手関節の伸展角速度の位相差が通常投球条件に比べ，変化投球条件において有意に減少した (p < 0.05)．この変化は，観察映像における基準動作と遅延動作の差異と共通の法則性を持つ．つまり，この結果は，基準動作と遅延動作の観察から肘関節と手関節の伸展における位相差を抽出し，自己の運動として実行したことを意味する． |
