Ocular pursuit in mentally retarded, cerebral-palsied, and learning-disabled children

We tested the following groups for visual pursuit abilities: 54 mentally retarded, 46 cerebral-palsied, and 131 learning-disabled children, 3 to 10 years of age. The resulting five behavioral scores, six directions, and total scores were analyzed for age trends. Comparisons were made between the handicapped groups and between the handicapped and normative samples. The scores were also correlated with other visual and postural abilities. All three handicapped groups scored lower than the normative group and also showed patterns different from the normative group and different from each other. The learning-disabled group most closely approximated the normative group's development patterns. Educational data were not able to be used, and we suggest that future research examine the correlations (both in handicapped and nonhandicapped children) of ocular pursuits and educational achievement, and also obtain more complete data on cerebral-palsied children. Therapists may find the visual pursuits test useful particularly when they want to evaluate a number of aspects of ocular pursuit functioning or when they desire more precision than what is usually available by simple observation.
