Eyes on hand-eyes on target?
Male Ss (N=60) were randomly selected to perform a modified version of a simple one-handed ballistic aiming task. Groups were aged 6-7 yr., 10-11 yr., and 19 or more yr.; within each group 10 Ss were able to see their hand and 10 Ss the target during task performance. A split-plot factorial design was used. Mean absolute error scores increased with distance, and at each age Ss with vision of target were more accurate than were Ss with vision of the hand. Vision, distance and the interactions of age and distance, and distance and vision were significant.
