A 125-item, two-choice discrimination test was given to 14 institutionalized mentally retarded children who were subsequently matched on several relevant variables. After Test I was given, all subjects received a music-preference test, and according to their preference were placed in one of two experimental treatment groups. Experimental Group A received music as reinforcement, and Group B received M & M's. The results indicated that a reliable difference was found between the two groups with the music group showing a highly significant increase in performance over Test I and Group B.
