Subnormal and normal children, of like mental age, were compared on a visual target localization task. Severely subnormal children were found to be less accurate than normal children, in conditions where they visually directed or visually guided their hand to the target and received visual knowledge of results. On visually directed localizations without knowledge of results or with proprioceptive knowledge of results (same hand) no significant difference was found between normal and severely subnormal children. Another experiment with moderately subnormal children revealed that developmental changes on visually directed and visually guided localizations are a function of mental age rather than chronological age.
