Over the past 10 years, we have seen a significant increase in the incidence of autism spectrum disorders (ASD) in the United States. In 2002, one in 150 children was diagnosed with autism; in 2006, one in 110 children was diagnosed with this complex condition. Experts note that the incidence continues to rise today, while medical, educational and clinical professionals work to identify the causes for autism. As families and society search for answers, key clinical resources have emerged. Research has indicated that the most successful method for addressing the behavioral deficits and excesses of autism is the discipline of Applied Behavior Analysis (ABA). Behavior analysis is not a new science, but its application has been demonstrated to be extremely effective in a variety of areas, especially in the field of autism and intellectual/developmental disabilities. (e.g., Lovaas, 1987; Howard et al., 2005; etc.).
