Two men with profound developmental disabilities used a mouth-wiping response instrumental to reduce drooling via a micro-switch-based program (i.e., a program in which the response was automatically monitored and followed by positive stimulation). The wiping response was performed via a napkin or a handkerchief placed inside a belt pocket. The micro-switch technology consisted of two mini-tilt sensors and a radio transmitter hidden inside the napkin, or an optic sensor and a radio transmitter fixed inside the belt pocket. The study was carried out according to a multiple baseline across participants and included a 3-month postintervention check. During the baseline, the participants' mean frequencies of mouth wiping were near zero, and mean percentages of wet chin intervals were about 45 and 50. During the intervention, the mean wiping frequencies increased to 1.6 and 1.9 per min, whereas the mean percentages of wet-chin intervals were mostly below 10. These values were maintained at the postintervention check. Implications of the findings and limitations of the study are discussed.

Key Words: drooling • mouth wiping • developmental disabilities • micro-switch-based program
