    Abstract:
    Study I used typical microswitch-cluster programs to promote adaptive responding (i.e., object manipulation) and reduce inappropriate head or head-trunk forward leaning with a boy and a woman with multiple disabilities. Optic, tilt, and vibration microswitches were used to record their adaptive responses while optic and tilt microswitches monitored their posture. The study included an ABB(1)AB(1) sequence, in which A represented baseline phases, B represented an intervention phase in which adaptive responses were always followed by preferred stimulation, and B(1) represented intervention phases in which the adaptive responses led to preferred stimulation only if the inappropriate posture was absent. Study II assessed a non-typical, new microswitch-cluster program to promote two adaptive responses (i.e., mouth cleaning to reduce drooling effects and object assembling) with a man with multiple disabilities. Initially, the man received preferred stimulation for each cleaning response. Then, he received stimulation only if mouth cleaning was preceded by object assembling. The results of Study I showed that both participants had large increases in adaptive responding and a drastic reduction in inappropriate posture during the B(1) phases and a 2-week post-intervention check. The results of Study II showed that the man learned to control drooling effects through mouth cleaning and used object assembling to extend constructive engagement and interspace cleaning responses functionally. The practical implications of the findings are discussed.
