This study investigated effects of a self-operated auditory prompting system, utilizing a Walkman-type cassette player, on the acquisition and maintenance of functional tasks by adolescents with severe handicaps. A multiple baseline design across tasks was employed to evaluate the effectiveness of the procedure for meal preparation, washing machine operation, and a vocational assembly task. Results indicated that each of the four participants successfully learned and maintained performance of each task.
