Vocabulary Selection in AAC: Application of Core Vocabulary in Atypical Populations

Abstract

On the American Speech-Language-Hearing Association Community for Special Interest Group 12, Augmentative and Alternative Communication (AAC), a community member introduced a discussion related to the selection and use of core vocabulary with students with severe intellectual or multiple disabilities. It was questioned whether or not core vocabulary determined in typically developing children was applicable to AAC intervention in these students. The present article reviewed a vast amount of language sample studies related to core vocabulary in both typical and atypical populations. It was concluded that core vocabulary is comparable for both populations in various contexts, with various communication partners, over various topics, and in various modalities of language use. Core vocabulary is thus of high importance for all AAC users, regardless of physical or intellectual disabilities.
