For this study 70 mentally retarded children. Medical diagnoses indicated that brain damage was the primary cause of retardation. These diagnoses as to etiology were made by a classification committee of the Receiving Centre of the Columbus State School. The 70 mentally retarded brain-injured children were selected from a larger group of children who had a diagnosis of brain-injury and who had received classifications on the basis of criteria in her behavioral descriptions of the four disability groups.
