摘要：Leisure items are commonly used as reinforcers in behavior-analytic applications. However, a defining feature of autism is the occurrence of stereotypy, and individuals with autism often engage leisure items in a stereotyped manner. The opportunity for stereotyped interaction may be the only aspect of a contingent stimulus that makes it a reinforcer for appropriate behavior. Therefore, this study investigated the effects of blocking stereotyped reinforcer interaction on reinforcer efficacy for 2 children with autism. Results showed that blocking stereotypic reinforcer interaction did not influence reinforcer efficacy.
