Applied Behavior Analysis

Applied behavior analysis (ABA) is a scientific discipline concerned with analyzing the principles of learning theory and systematically applying this technology 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 experimental research).

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. This approach often seeks to develop replacement behaviors which serve the same function as the aberrant behaviors.

Methods in applied behavior analysis range from early intensive behavioral interventions for children with an autism spectrum disorder (ASD) to research on the principles influencing criminal behavior. However, ABA has also been brought to bear on a wide range of areas and behavioral problems, exemplified by the following: 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.
