Using Simple Hand-Movement Responses with Optic Microswitches with Two Persons with Multiple Disabilities

Abstract
In this study, we assessed whether a program involving simple hand-movement responses combined with optic microswitches and followed by preferred stimuli would be successful (i.e., increasing responding and stimulation) with two persons with multiple disabilities. Data showed that both persons reached fairly high levels of responding during intervention and retained their achievement through subsequent maintenance periods of 3 or 6 months. Procedural issues, practical implications of the findings, and measures for promoting long-term response maintenance–extensions were discussed.
