Stereotypy is commonly defined as “frequent repetition of the same, typically purposeless movements, gestures, vocal sounds or utterances”, (Merriam-Webster Collegiate Dictionary, n.d.) and is a common perseverative behavior that is observed among children with autism spectrum disorder and other developmental disabilities. Stereotypy may result in interference with educational and therapeutic activities for the child. The present study sought to determine if the punishment procedure, response interruption and redirection (RIRD), is effective in reducing stereotypy during natural environment training without demonstrating other undesired behaviors that are associated with punishment procedures, including aggression, avoidance of staff, etc. Results of this study indicated that RIRD was effective in reducing stereotypy for one participant, and did not result in increased aggression, avoidance of staff, or decreased appropriate vocalizations for either of the participants.
