Abstract
This study investigated developmental trends in two aspects of kinesthesia. The kinesthesia test of the Southern California Sensory Integration Tests was administered to 80 children ages 6, 9, 12, and 15. The test was scored for the ability to reproduce a movement toward a target with angular accuracy (angle error) and for the ability to judge how far to move (distance error). Although improvement on both measures was found over the age range studied, the differences between the groups were significant only with younger children. Six-year-olds were significantly different from the three older groups in both distance error and angle error. In angle error there was also a significant difference between 9-year-olds and 15-year-olds. Both measures showed a marked drop in variability after 6 years of age. A moderate correlation (r = .54) was found between the two measures.
