Applied behavior analysis (ABA) is a way to help organisms change their behavior, and to identify the environmental contingencies that result in this behavior change. ABA, the application of behavior analysis, is based on the scientific approach known as radical behaviorism, which views covert events as behavior that are to be subjected to the same conditions as overt behavior. ABA can be used as a treatment for animals, mental disorders, and developmental disabilities, and is based on the principles of behavior that were discovered using experiments.
