Overview of Augmentative and Alternative Communication and Special Considerations for Individuals With Angelman Syndrome

Abstract

The primary purpose of this chapter is to provide readers an overview of augmentative and alternative communication (AAC) as a prelude to subsequent chapters exploring this topic in greater depth. Basic material pertaining to assessment and intervention practices and principles is presented. The chapter begins by differentiating the two applications of AAC as augmentations of or alternatives to individuals’ existing methods of communication. Information is provided regarding the impact of AAC systems on speech. Next, the four components of AAC systems; (a) symbols, both aided and unaided; (b) techniques, which include direct selection and scanning; (c) devices and other aided and unaided methods; and (d) strategies are reviewed. Educators and others are encouraged to address all four of these components when designing and implementing AAC programs that consider individuals’ current and future communication needs.
