This study investigated the role of vision in the encoding and reproduction of movement. Kinaesthetic reproductions of a kinaesthetically presented two-dimensional movement were compared with reproductions where vision was present either during the standard or at reproduction. The main finding was that the presence of vision during the standard resulted in poorer accuracy and greater underestimation of movement size than when it was absent throughout or present during reproduction. The presence of vision during the standard, however, resulted in less distortion of the linear components of movement shape although no such effect was found for the angular components. The initial direction of movement was reproduced more accurately where visual experience of the movement was given, either during the standard or during reproduction.
本研究调查了视觉在动作编码与再现中的作用。将对以动觉方式呈现的二维动作进行的动觉再现，与在标准阶段或再现阶段有视觉参与的再现情况进行了比较。主要发现是，在标准阶段有视觉参与时，与全程无视觉参与或仅在再现阶段有视觉参与相比，准确性更低，且对动作大小的低估程度更大。然而，在标准阶段有视觉参与时，动作形状的线性成分的扭曲较少，尽管在角度成分上未发现此类影响。在标准阶段或再现阶段提供动作的视觉体验时，动作的初始方向再现得更准确。
