Gather ‘round and listen close: Increasing responding to voices in children with autism

Abstract

ABSTRACT We investigated the effects of a response-contingent pairing (RCP) procedure on responses to voices for preschoolers with autism spectrum disorder (ASD). The participants were 4 preschool males who attended full-day special education classes utilizing a behavior-analytic system of schooling. The participants were chosen due to (a) their low numbers of observing responses to voices during initial probe screenings for observing responses to different forms of voice stimuli, and (b) their slow rates of mastery of educational objectives in their Individualized Education Programs (IEPs). We used an iPad-based RCP voice conditioning protocol during which we taught the participants to touch a correct stimulus on a screen (a red circle) that would activate 10 s of either sung or spoken song lyrics or spoken storylines. The conditioning component involved a response-contingent pairing procedure; contingent on a correct selection response, the investigators immediately paired the voice output with preferred edibles and/or light, preferred physical contact for the entire interval. We employed a multiple probe design across participants for five observing responses to voices (OV) following the intervention. The results showed increases for all four participants’ OV responses. We explore future implications of research involving increasing preferences for voices, and discuss other potential dependent variables.
