Abstract
OBJECTIVE: To compare how quickly children with autism spectrum disorder (ASD) acquired manual signs, picture exchange, and an iPad/iPod-based speech-generating device (SGD) and to compare if children showed a preference for one of these options.
METHOD: Nine children with ASD and limited communication skills received intervention to teach requesting preferred stimuli using manual signs, picture exchange, and a SGD. Intervention was evaluated in a non-concurrent multiple-baseline across participants and alternating treatments design.
RESULTS: Five children learned all three systems to criterion. Four children required fewer sessions to learn the SGD compared to manual signs and picture exchange. Eight children demonstrated a preference for the SGD.
CONCLUSION: The results support previous studies that demonstrate children with ASD can learn manual signs, picture exchange, and an iPad/iPod-based SGD to request preferred stimuli. Most children showed a preference for the SGD. For some children, acquisition may be quicker when learning a preferred option.
