A rotary pursuit task was administered to 32 boys and 32 girls, kindergarten through third grade. Age, speed (33 and 45 rpm), and experimental trial were significant but sex differences were not; practice trials significantly magnified the effects of age and speed. Kindergarten children found the task very difficult and the oldest children did not approach adult performance. The data indicate that experimental measurement of specific motor abilities is possible at these age levels.
