Three experiments, involving five students (aged 13-20) with profound, multiple handicaps, showed that the students could effectively use microswitches to demonstrate toy preferences, to indicate preferences for social attention, and to make specific requests of educational staff in school and community settings.

Three individuals with multiple severe disabilities were taught an appropriate response to problem behaviors, but the response was less efficient than the problem behavior on physical effort, schedule of reinforcement, or stimulus-reinforcer time delay. The response did not compete successfully with the problem behaviors until a new, more…

Two severely handicapped children (ages 5-6) exhibiting self-injurious behavior were treated with negative reinforcement (brief escape from grooming activities) contingent upon a behavior that was incompatible with self-injury (pressing a microswitch that activated a "stop" message). Treatment led to decreased self-injury, which was maintained at…

Behavior analysis was implemented in a school for 38 children with multiple disabilities, following staff training. Results over two years showed educationally significant increases in trials taught, correct student trials, and objectives achieved. During followup, results indicated maintenance and social validity of the behavior analysis package.…
