• Correspondence between mental and physical movements of one's own hands was investigated. Line drawings of a human hand were shown in one of five forms; each form occurred as either a left or a right hand, and could appear in any one of eight directions in the picture plane. The subjects were asked to imitate the drawing by moving their own hands and to rate the physical difficulty in the imitative movements. The measured difficulty was compared with the previous data; reaction time (RT) in the identification of the left-right version of the same stimuli (Sekiyama, 1982). Both difficulty and RT showed similar trends, as a function of angular departure of the stimuli from upright, suggesting that the left-right identification is based on mental movements of representations of subjects' own hands. It was argued in terms of kinesthetic information preserved in representations.
