Abstract

10 boys and 10 girls were tested at each of six age levels (6, 7, 8, 12, 13, and 14 yr.). All of the children were right-handed, and at each age level the groups did not differ in age, WISC Full Scale IQ, or educational attainment. The groups were compared on motor tasks (strength and speed) and tactile-perceptual tasks (finger localization and symbol recognition). The performances of the right and left hands were compared. The results indicated clear right-hand motor superiority, but no “sidedness” effect for the tactile-perceptual measures. The implication of these results for brain-behaviour relationships was discussed.
