Effects of social interaction on leisure item preference and reinforcer efficacy for children with autism.

Abstract

We replicated and extended Kanaman et al. (2022) by comparing outcomes of solitary (leisure items only), social (leisure items with social interaction), and combined (leisure items alone and leisure items with social interaction) stimulus preference assessments to determine the extent to which the inclusion of social interaction influenced the outcomes of preference assessments for five children with autism. We then conducted reinforcer assessments to determine the reinforcing efficacy of high- and low-preferred leisure items when presented with and without social interaction. The results showed that both high- and low-preferred items functioned as reinforcers to varying degrees for all participants and the inclusion of social interaction increased the reinforcing efficacy of some items for all participants. Additionally, the results showed that combined preference assessments predicted reinforcer assessment outcomes for two of five participants but produced false-negative outcomes for three participants. Clinical implications and directions for future research are discussed.
