Abstract

|
|
The purposes of this literature review were to analyze empirical studies on Augmentative and Alternative Communication (AAC) for individuals with autism and to examine current research trends in this matter. To achieve these purposes, 12 studies on AAC for individuals with autism, published between 2000 and 2010, were selected and analyzed with characteristics of participants, the types of AAC and dependent variables, research methodologies, and results. The results showed that 75% of participants were children with autism under 7 years old. 11 studies used picture-based AAC (i.e., PCS or PECS), and only one study used VOCA for enhancing social interactions between children with and without disabilities. In terms of research methodologies, single-subject research designs were employed in 11 studies, and group design in only one study. All studies reported the positive results of AAC’s uses on communication and on social interaction. Based on the results, issues and future research directions were discussed.
