  • Title: The effects of blocking mouthing of leisure items on their effectiveness as reinforcers.
    Author: Tarbox RS, Tarbox J, Ghezzi PM, Wallace MD, Yoo JH.
    Journal: J Appl Behav Anal; 2007; 40(4):761-5. PubMed ID: 18189113.
    Abstract:
    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.
