Video modeling is a strategy used to teach learners new skills by viewing a video of a model engaging in a target behavior and then having the learner imitate the behavior (Cooper et al., 2019). Much research has been conducted on the effectiveness of video modeling when compared to in vivo modeling, but there are still various limitations to consider, including its effectiveness as a solo intervention, who are the most impactful models to include, and the effectiveness of the intervention for certain populations. The purpose of this study is to evaluate the use of video modeling as a solo intervention to teach tacting letter sounds or letter blends to children with ASD with limited vocal repertoires and to evaluate the effectiveness of different models in the video recordings. Results suggested that the sibling model was the most effective for one participant after the inclusion of a training phase. Results were inconclusive for the second participant.
