Comparing resetting to non‐resetting DRO procedures to reduce stereotypy in a child with autism

We compared a resetting to a non‐resetting differential reinforcement of other behavior (DRO) procedure to reduce stereotypy exhibited by young boy with autism. During the resetting DRO, a reinforcer was delivered contingent upon the absence of stereotypy during the DRO interval. If stereotypy occurred, the DRO interval was immediately reset. The non‐resetting DRO procedure was identical, except that contingent upon stereotypy, the DRO interval continued until it expired; a new DRO interval then began. Results indicate that the DRO procedures were equally effective to reduce stereotypy, but the participant preferred the resetting DRO procedure.
