Promoting mouth-drying responses to reduce drooling effects by persons with intellectual and multiple disabilities: a study of two cases.
This study assessed the use of microswitch technology to promote mouth-drying responses and thereby reduce the effects of drooling by two adults with severe intellectual and multiple disabilities. Mouth-drying responses were performed via a special napkin that contained pressure sensors, a microprocessor and an MP3 to monitor the responses and ensure positive stimulation contingent on them. Initially, the responses produced 10 or 15 s of preferred stimulation. Subsequently, preferred stimulation was supplemented with matching periods of lower-grade stimulation to extend the inter-response intervals. Results showed that both participants (a) learned to dry their mouth consistently and reduce their chin wetness during the intervention, (b) stabilized their responding at lower frequencies as the lower-grade stimulation was added to the preferred stimulation, and (c) maintained the latter levels at a 3-month follow-up. Procedure and response conditions and outcome implications are discussed.
