This study investigated the task performance of cerebral palsied children under conditions of reduced auditory input and under normal auditory conditions. A nonhandicapped group was studied in a similar manner. Results indicated that under conditions of reduced auditory input, cerebral palsied children showed some positive change in performance on a recall of missing picture test, an attention test, and on parts of a learning test and digit span test. They showed no change in performance on visual-perceptual or perceptual-motor tasks. The nonhandicapped children showed no significant change in performance under conditions of reduced auditory input.
