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.
本多项基线研究旨在探讨自闭症个体通过观察视频模型，在多大程度上能够学会操作语音生成设备（SGD）来请求他们喜欢的物品。干预措施包括让每个参与者观看时长为 10-15 秒的视频模型，该模型展示了使用 SGD 请求喜欢的物品的过程。基线、干预和泛化均在公立学校的特殊教育教室中进行。观看完视频模型后，有两名参与者无需任何提示或线索，便能够使用 SGD 来请求他们喜欢的物品。然而，参与者并没有将使用 SGD 请求他们喜欢的第二个物品的技能进行泛化。本研究初步证明，视频模型可以用于教授自闭症和严重认知障碍个体使用 SGD 来请求物品的技能。
