視覚的運動の予測可能性が自己帰属感の生起過程に及ぼす影響の調査

抄録

Previous studies of the recognition process of self-attribution conducted that it is mainly caused by congruence between visual and proprioceptive information, and congruence between visual information and prediction from motor commands. However, they did not declare which congruence acts the primary role in the process during the voluntary movements. We conducted a user study that distinguishes proprioceptive information and prediction from motor commands by displaying modified images of the subjects’ hands in various rotation angles, that introduced the conflict between visual and proprioceptive information. The hand motion of the subjects was restricted so that they could predict the visual motion of the images of their hands by the motor command even while the images were rotated. The result indicates that the prediction of the motion plays a primary role in the recognition process of self-attribution, and this predictability depends on the motion pattern and the appearance of the hand images.
