A projective role taking task (RTT) was revised with respect to procedure and scoring categories for use with the mentally retarded. The revised RTT was administered to 123 educables. Results indicated significant associations between mental age and various indices of the retardates' role taking behavior. These associations remained significant when chronological age was controlled. Also, both interjudge agreement and test reliability met levels established in previous studies of intellectually normal individuals. It was concluded, therefore, that the revised RTT was both reliable and valid with the retarded and provided a basis for study of the relationship between role taking ability and behavioral indices of social adequacy.
