This study investigated the effects of an extended, systematic training program of sensory-motor activities on sensory-motor, visual perception and concept-formation tasks. 10 identical criterion measures were utilized as pretests and posttests in conjunction with a 2-mo. training program. Both the experimental and control groups' mean scores on all criterion measures reflected improvement from pretest to posttest administrations. However, when the analysis of covariance was applied, no significant differences were evident between the adjusted posttest mean scores of the two groups.
