Moreover, the self-inflicted biting behavior was found to be maintained by sensory stimulation (alone condition). Given these, a structured behavioral intervention, consisting of differential reinforcement of alternative behaviors, coupled with extinction targeted to each function of the behavior, was effective in reducing other-inflicted biting behavior in the demand conditions (67% reduction) and in the tangible conditions (95% reduction) as well as reducing self-inflicted behaviors in the alone conditions (100% reduction). More appropriate, adaptive behaviors like compliance, picture-assisted requests, and oral sensory activities also increased significantly. <strong>Conclusion:</strong> These findings indicate that assessment and treatment based on the principles of applied behavior analysis can reduce not only problematic behaviors but also improve adaptive functioning. https://www.behavsci.ir/article_156243_996886fdb7bbc3c032caf8b543bfe56a.pdf
