Abstract:
In a sample of 55 mentally retarded subjects (M age = 14 yr., 1 mo.) the relations between some perceptual and cognitive Rorschach indices, including the Becker's Genetic Level Score, and Wechsler Scale scores were studied. The mean Developmental Score did not increase across ages and was higher for girls than for boys, while Verbal and Performance IQs were lower for girls. The correlations confirm the hypothesis that for mentally retarded persons WISC-R scaled scores and Rorschach cognitive indices are different measures of intellective functioning. The findings are discussed with reference to the assessment and rehabilitation of retarded subjects.
