The relative accuracy of the left and the right arms in active positioning was studied in a group of 24 male right-handed undergraduates. The task required active positioning of the left and right arms at each of the four angular positions (30°, 45°, 60°, and 75°). The left arm was more accurate in active positioning than the right arm. There was a progressive increase in error for both arms as the arms flexed more in reducing the angle at the joint. Results are discussed in light of suggestions concerning the superiority of the right hemisphere in the processing of kinesthetic and proprioceptive information.
