Abstract: Thirty mildly mentally retarded subjects were asked to duplicate rhythm patterns via tactile, auditory, auditory-visual, and auditory-visual- tactile conditions. Subjects were grouped according to classroom assignments: Primary, ages 6-18; Intermediate, ages 9-12; and Adolescent, ages 13-18. An analysis of variance revealed a significant main effect for sensory condition and a significant interaction effect. Scheffe post hoc analyses revealed that all groups scored significantly lower on the tactile tasks, and that the primary group scored significantly lower than the other two groups on the tactile tasks only.
