Reducing Self-Stimulatory Mouthing Behaviors in Deaf-Blind Children

Three procedures for reducing inappropriate mouthing behavior in deaf-blind school children are described: (1) contingent reinforcement and a signaled “No” during a training session for appropriate play with toys, (2) two forms of contingent presentation of an aversive taste to reduce inappropriate self-stimulatory and self-injurious mouthing, and (3) contingent presentation of an aversive taste, a signaled “No,” and a cueing signal to reduce inappropriate finger-sucking. The effectiveness and efficiency of the three procedures are compared.
