The purpose is to examine whether motor space might be heterogeneous in movement reproduction with regard to kinesthetic cues of location and distance. Twenty blindfolded subjects were asked to reproduce points in space or length of ten centimeters in motor space. Three motor spaces criteria-movements were set in relation to subject's body positions: median line, shoulder, and outside of shoulder. Chief findings were as follows: (a) Although the difference of motor space was not found with distance cues, the difference was significant with location cues, indicating that the movements were less undershot at median line space than at the space outside of shoulder. (b) The movements tended to be reproduced more exactly at median line space than at the space outside of shoulder. The present study suggested that cognition of space related to body image played more important role in the movement reproduction with the location cue than in the one with the distance cue.
