Abstract

Children with autism often display repetitive, stereotypical movements with toys in lieu of appropriate play skills. Unlike typically developing children, they do not vary their play with toys. Therefore, the purpose of this study was to determine whether three preschoolers with autism would vary their play actions when exposed to a lag schedule of reinforcement and physical prompting procedure. All three participants demonstrated varied play actions with the lag schedule and prompting procedure in place. These behaviors maintained when a probe was conducted two weeks later in the absence of the lag schedule. Although responding was high in the 2-week probes, participants demonstrated stereotypical patterns of behavior. This indicates a lag schedule and prompting procedure may be effective for evoking varied behavior in play.
