“…First, the function of video modelling was isolated from other methods in as natural an environment as possible (e.g., Morgan & Salzberg, 1992). Second, the videotape format used in this study obtained all the advantages of convenience, standardisation, and efficiency that may be difficult to achieve with in vivo formats (Poche, Yoder, & Miltenberger, 1988). Third, not only were short video clips shown to be effective (i.e., 35 secs), but also these video presentations resulted in rapid changes in behaviour, that required no further prompts (in terms of video presentations) in subsequent assessments across other stimuli.…”
