Video modeling to teach Mand for Information in children with Autism, based on Verbal Behavior Approach

Introduction: Mand repertoire is fundamental for development of languageas communicative behavior. In particular, in Verbal Behavior Approach Mand for information specifies informations as reinforcement. In this study, we wanted to investigate the use of Videomodeling strategies to teach independent mands for information to children with ASD level 2.

Methods: Using ad adapted alternating treatment design we compared two different teaching conditions: Video Modeling Condition; and vocal model prompt Condition. Partecipants were four children with ASD aged between 4.5 and 6 years old.

Results: Using video modeling to teach and for information has shown has given good results, especially in children who have shown a difficulty in discriminating the echoic prompt. In fact, while children who took the vocal model prompt showed best performance in both condition, children who showed difficulties in discriminating the stimulus initially learned only mands taught by videomodeling, generalizing the learning to the other topography later.
