"Using stereotypy as reinforcement" : for alternative behavior in a chained schedule

Abstract

Some individuals with autism spectrum disorder (ASD) engage in stereotypy, or repetitive behavior typically maintained by automatic reinforcement. Chronic stereotypy, especially at high frequencies, can interfere with learning and cause social stigmatization. Response blocking and response interruption and redirection (RIRD) have been found to be effective for reducing motor and vocal stereotypy. Previous literature has evaluated stereotypy as reinforcement for alternative behaviors, such as functional play or work tasks. The current study sought to replicate and extend previous studies by evaluating the effectiveness of a chained schedule on gaining stimulus control over stereotypy and increasing the complexity of alternative behaviors. Preliminary results indicate that chained schedules are effective at reducing stereotypy during the s-delta and increasing the complexity of alternative behaviors. These results emphasize the importance of providing contingent access to stereotypy when attempting to gain stimulus control over stereotypy.
