This study evaluate the effects of an intervention package, including non-contingent reinforcement(NCR), to reduce severe problem behaviors of a student with autism and mental retardation in the daily program of a special needs school. Prioritizing the practicality of assessment and intervention procedures, we relied on interview and direct observation to identify the function of the problem behaviors and selected a maintained reinforcer that was easily delivered among alternatives. In Intervention 1, NCR was provided, with extinction (EXT) and contingent response to communicative behaviors(CR). In Intervention 2, visual schedule and peer mediated strategy, in addition to NCR, EXT, and CR, were introduced. Reduction of the problem behaviors occured following Intervention 1, and more substantial occurred following Intervention 2. Additionally, increases in class participation were noticeable after Intervention 2. Additionally, increases in class participation were noticeable after Intervention 2 was implemented. On the basis of these results, we discussed practical ways of implementing NCR interventions in school settings where controlling environments is typically difficult.
