This multiple baseline study investigated to what extent individuals with autism would learn to operate a speech generating device (SGD) to request a preferred object by observing a video model. The intervention consisted of each participant viewing a 10- to15-s video model that demonstrated the requesting of a preferred object using a SGD. Baseline, intervention and generalisation were all implemented within a public school, special education classroom. After viewing the video model, two participants displayed the ability to request preferred items using the SGD without prompting or cues. However, the participants did not generalise requesting using the SGD to a second preferred object. The study provides preliminary evidence that video modelling can be used to teach individuals with autism and severe cognitive disabilities requesting skills using an SGD.
