<P> Applied behavior analysis (ABA) is a scientific discipline concerned with applying techniques based upon the principles of learning to change behavior of social significance . It is the applied form of behavior analysis; the other two forms are radical behaviorism (or the philosophy of the science) and the experimental analysis of behavior (or basic experimental research). </P> <P> The name "applied behavior analysis" has replaced behavior modification because the latter approach suggested attempting to change behavior without clarifying the relevant behavior - environment interactions . In contrast, ABA tries to change behavior by first assessing the functional relationship between a targeted behavior and the environment . Further, the approach often seeks to develop socially acceptable alternatives to aberrant behaviors . </P> <P> ABA has been brought to bear on a wide range of areas and behavioral problems . Examples include such things as early intensive behavioral interventions for children with an autism spectrum disorder (ASD), research on the principles influencing criminal behavior, as well as HIV prevention, conservation of natural resources, education, gerontology, health and exercise, industrial safety, language acquisition, littering, medical procedures, parenting, psychotherapy, seatbelt use, severe mental disorders, sports, substance abuse, phobias, pediatric feeding disorders, and zoo management and care of animals . </P> <P> ABA is an applied science devoted to developing procedures which will produce observable changes in behavior . It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, but it uses principles developed by such research, in particular operant conditioning and classical conditioning . Behavior analysis adopts the viewpoint of radical behaviorism, treating thoughts, emotions, and other covert activity as behavior that is subject to the same rules as overt responses . This represents a shift away from methodological behaviorism, which restricts behavior - change procedures to behaviors that are overt, and was the conceptual underpinning of behavior modification . </P>

All of the following are dimensions of applied behavior analysis except
