TitleComparing Three Augmentative and Alternative Communication Modes for Children with Developmental Disabilities
Publication TypeJournal Article
AbstractWe compared acquisition, maintenance, and preference for three AAC modes in four children with developmental disabilities (DD). Children were taught to make general requests for preferred items (snacks or play) using a speech generating device (SGD), picture-exchange (PE), and manual signs (MS). The effects of intervention were evaluated in a multiple-probe across participants and alternating treatments design. Preference probes were also conducted to determine if children would choose one AAC mode more frequently than the others. During intervention, all four children learned to request using PE and the SGD, but only two also reached criteria with MS. For the AAC preference assessments, three participants chose the SGD most frequently, while the other participant chose PE most frequently. The results suggest that children’s preference for different AAC modes can be assessed during the early stages of intervention and that their preferences may influence acquisition and maintenance of AAC-based requesting responses.
