Abstract
The present study involved comparing the acquisition of multi-step requesting and social communication across three AAC options: manual signing (MS), picture exchange (PE), and speech-generating devices (SGDs). Preference for each option was also assessed. The participants were two children with autism spectrum disorders (ASD) who had previously been taught to use each option to request preferred items. Intervention was implemented in an alternating-treatments design. During baseline, participants demonstrated low levels of correct communicative responding. With intervention, both participants learned the target responses (two- and three-step requesting responses, greetings, answering questions, and social etiquette responses) to varying levels of proficiency with each communication option. One participant demonstrated a preference for using the SGD and the other preferred PE. The importance of examining preferences for using one AAC option over others is discussed.
