What is ABA?

“ABA” stands for Applied Behavior Analysis. ABA is a set of principles that form the basis for many behavioral treatments. ABA is based on the science of learning and behavior. This science includes general “laws” about how behavior works and how learning takes place. ABA therapy applies these laws to behavior treatments in a way that helps to increase useful or desired behaviors. ABA also applies these laws to help reduce behaviors that may interfere with learning or behaviors that may be harmful. ABA therapy is used to increase language and communication skills. It is also used to improve attention, focus, social skills, memory, and academics. ABA can be used to help decrease problem behaviors. 


ABA is considered an evidence-based “best” practice treatment by the US Surgeon General and by the American Psychological Association. “Evidence based” means that ABA has passed scientific tests of its usefulness, quality, and effectiveness. 


ABA therapy includes many different techniques. All of these techniques focus on antecedents (what happens before a behavior occurs) and on consequences (what happens after the behavior). One technique is “positive reinforcement.” When a behavior is followed by something that is valued (a reward), that behavior is more likely to be repeated. ABA uses positive reinforcement in a way that can be measured in order to help bring about meaningful behavior change. 


A few types of therapies based on ABA principles are discrete trial learning, incidental teaching (or natural environment training), verbal behavior, pivotal response training, functional communication training, and more.
