Download Article PDFThis study investigated the effectiveness of an intervention package incorporating an iPad-based augmentative and alternative communication (AAC) application, Proloquo2Go, to enhance wh-question-answering skills in a 15-year-old adolescent with autism. A multiple baseline design across three types of wh- questions (what, where, who) was employed. The intervention package included a least-to-most prompting hierarchy, interval reinforcement, cue cards, and question-related visuals. Results indicated a functional relationship between the intervention and improved wh-question-answering skills. The participant demonstrated generalization of learned skills to novel settings, people, and questions during generalization probes. The findings suggest that iPad-based AAC interventions can be effective in improving communication skills in adolescents with autism.
