Applied behavior analysis (ABA) is the science in which strategies derived from the principles of behavior and learning are systematically applied to improve socially significant behavior (Cooper, Heron, & Heward, 2007). ABA is used to teach and maintain skills such as communication, social interaction, academics, self-care, recreation, and vocational skills. ABA is also used to reduce interfering behaviors such as stereotypy, aggression, and self-injurious behavior. A program using ABA individualizes the teaching strategies for each specific person’s needs so that they can learn the skills needed to live a happy, meaningful, productive life. ABA’s effectiveness lies in its foundation in scientific research that has been conducted in the natural setting for decades.
