Transferring picture exchange requests to receptive identification for children with ASD

The purpose of this study was to evaluate a procedure to transfer stimulus control from picture exchange requests to receptive identification. Three children with autism spectrum disorder (ASD) and absent receptive identification repertoires participated. An adapted alternating treatment design was used. During intervention, two high-preferred and two low-preferred targets were available during picture exchange requesting sessions. Participants requested primarily for one or both high-preferred targets. During receptive identification instructional sessions, one participant acquired one high-preferred target, one participant acquired all targets, and one participant demonstrated no improvements. Generalization to novel examples of targets was assessed pre- and post-intervention and programmed if necessary. One participant generalized his acquired high-preferred target without programming. Another participant generalized a high-preferred and a low-preferred target without programming, and acquired a high-preferred target with programming. Potential benefits of this intervention and suggestions for future research are presented.
