Fifty-six studies from 1980 to 2007 involving the use of augmentative and alternative communication (AAC) by individuals with autism were reviewed. The majority of the studies used single-subject research designs and emphasized language production skills. Many investigations were held in artificial language learning settings, and a few involved parents and teachers as intervention agents. Gaps in the provision of the participants' cognitive, language, and sensory-motor measures were detected in the analysis of the 51 studies that provided individual participant data. Despite these limitations, this report revealed that communication interventions for individuals with autism that have incorporated sign language/total communication, visual-graphic symbols, and/or speech generating devices have had successful outcomes.
