Abstract
Light-eyed individuals generally perform better at self-paced activities while dark-eyed individuals perform better at reactive activities. A 2 (boy, girl) by 2 (light-eyed, dark-eyed) by 4 (Grades 1, 2, 3, 4) analysis of variance was performed on number of rope jumps in 15 sec. There was no difference among the children with different eye-colors, but there were expected differences by grade and sex. The older children of higher grades jumped more times than the younger children of lower grades, and girls jumped more than did boys.
