A History of Augmentative and Alternative Communication for Individuals with Severe and Profound Disabilities

Abstract

Augmentative and alternative communication (AAC) is a prominent component in the development of support services for individuals with disabilities, especially those with severe disabilities. In this article we provide an overview of the historical development of AAC services, tracing their evolution over the past half-century through four specific themes: social change and legislation, assessment, intervention, and family and cultural issues. © 2004, Sage Publications.
