posted on 2023-05-16, 18:12 authored by Seung-Hyun, S, Sigafoos, J, O'Reilly, M, Lancioni, GEThis study compared acquisition and preference for two types of augmentative and alternative communication (AAC) systems in three pre-schoolers with autism. Acquisition of requesting behaviour using a picture-exchange system vs a voice-output communication aide (VOCA) was compared in an alternating treatments design. Following acquisition, both ACC systems were simultaneously available and the child could select which one of the two systems to use. There was little difference between picture-exchange and VOCA in terms of acquisition rates. Two children demonstrated a consistent preference for picture-exchange and the third showed a preference for the VOCA. Both speed of acquisition and system preference should be considered when designing AAC interventions for children with autism and related developmental disabilities. © 2006 Informa UK Ltd.
