A comparison of video modelling techniques to enhance social-communication skills of elementary school children

This study compared the effect of video modelling with and without embedded narration on the social communication skills of four typical school children. Target behaviours were appropriate conversational turn taking and correct conversational body posture. The differential effects of the two video modelling procedures were assessed using Alternating Treatments Designs with target behaviours and treatment conditions counterbalanced. Responding on both target behaviours was below normative levels during baseline assessment but improved across the alternating treatments phase, and remained at or above normative levels across an optimal treatments phase and in follow-up. Video modelling with narration was more efficient than video modelling without narration for all four participants and more effective for two. Implications of the findings and suggestions for future research are discussed.
