240 Ss in 6 age groups (8-18 years) each faced and imitated a person who, over 12 trials, touched a body part or object on his left or right side with his left or right hand. With increasing age, the mean number of responses paralleling the moders movement as in a mirror decreased, the mean number of correct transpositions of the moders movement increased, and the mean number of excessive right-handed and unilateral responses decreased (all significant, p < .001). The findings support the idea that left-right transposition requires the internalization of the left-right distinction occurring in action and the representational coordination of perspectives.
