The present study was designed to investigate the role of sensory extinction and sensory reinforcement in the moti- vation of self-injurious behavior. The intervention was based on the assumption that each subject's SIB behavior was motivated by the sensory consequences of the behavior. A pre- assessment phase was used to select appropriate sensory ex- tinction devices and sensory reinforcing toys, although no appropriate sensory toys could be identified. Thus, treat- ment consisted solely of sensory extinction using a reversal design. Results showed that the sensory extinction devices reduced tactile stimulation of face slapping and pica for two developmentally disabled adults. Maintenance of treat- ment gains was programmed by fading the device both on the unit and in the experimental setting. This procedure was minimally successful in achieving long term reduction in SIB.
