Studied sex-related differences in the linkage between verbal and analytic intelligence and performance on tasks of social interaction. 90 boys and girls from 2nd, 3rd, and 4th grades served as Ss. Analytic intelligence was a good predictor of communication scores for boys but not for girls. Verbal ability was no better a predictor for girls than boys. The correlational evidence indicates that conventional intelligence tests predict social perspective taking as well as Piaget's measure of spatial perspective-taking ability.
