Using video modeling on an iPad to teach generalized matching on a sorting mail task to adolescents with autism

Two multiple probe designs across three and four participants evaluated the effects of video modeling to teach a matching response (sorting mail) to seven adolescents with autism. Participants were instructed on one set of responses (five mail pieces) using video modeling, while concurrently monitoring two other sets for generalization effects. Results indicated that three participants learned their target set and generalized to the untrained sets, and two participants required an error correction procedure to achieve or approach mastery on their target set. Two participants did not acquire target sets with video based instruction. Data on setting generalization and maintenance are also provided for the participants who reached mastery. Participant variables that may relate to responding, limitations to the study, and directions for future research on video based instruction are discussed. (C) 2013 Elsevier Ltd. All rights reserved.
