Examines the changes that occur in sensorimotor coordination after viewing the prism-displaced image of the hand. 4 types of explanation for the changes are advanced: (a) visual, (b) proprioceptive, (c) motor, and (d) sensorimotor. Each predicts different consequences on different tests of coordination; i.e., reaching for visual targets, orienting head to hand, orienting eye to hand, and repositioning the hand in a learned posture. The results of 4 experiments with a total of 32 undergraduates and college employees were consistent only with the sensorimotor explanation. Findings suggest a change in the control and assessment of coincidence between the direction indicated by the exposed arm and that of either a sensed external object or other body part. (24 ref.)
