Abstract: The purpose of this study was to examine the influence of video and music reinforcers on the performance of an upper-body strengthening exercise program on the preferred arm of six nonambulatory youth, ages 10 to 15 years who were profoundly mentally retarded. An AB1B2 design was used to determine the difference in performance of the exercise under the baseline condition of no reinforcement (N = 6); and under the three treatment conditions of verbal praise only (n = 2); preferred video and music reinforcement only (n = 2); and verbal praise plus preferred video and music reinforcement (n = 2). Based on visual inspection of the data and use of the split-middle technique, subjects receiving verbal praise only or verbal praise plus video or music reinforcement improved their exercise performance over time. The two subjects receiving video and music reinforcement only, however, declined in performance after the baseline phase and demonstrated no improvement over time. (42 ref)
