“ABA” is the common term for Applied Behavior Analysis, which involves examining behaviors by looking at the duration, intensity and frequency of a behavior that is occurring. The principles of behavior are applied to help improve appropriate and socially significant behavior, as well as identifying the variables that can lead to behavior improvement. By applying ABA principles, you can understand how to reinforce appropriate behaviors, extinguish inappropriate behaviors and teach replacement behaviors. ABA is the only scientifically validated method for the treatment of Autism. There are various ABA approaches to utilize such as Pivotal Response Training (PRT), Discrete Trial Training (DTT), Picture Exchange Communication System (PECS), Social Skills training techniques and Self Management, all of which are critical when teaching children/individuals with Autism. The field of behavior analysis deals with the study of both learning and behavior. Behavior analysis is an applied science that develops methods of changing behavior and provides services to very diverse behavioral needs.
