What Is ABA Therapy?

At its heart, ABA is a scientific approach to understanding and changing behavior. It applies principles of learning theory—rooted in the work of psychologists like B.F. Skinner—to real-world situations. The infographic describes ABA as using “scientific principles” to focus on how behaviors are influenced by their consequences, aiming to increase positive, socially significant actions while decreasing harmful ones.

In practice, ABA isn’t about “fixing” your child; it’s about teaching functional skills and reducing barriers to independence. Therapists observe the “A-B-Cs”: Antecedents (what triggers a behavior), Behavior (what happens), and Consequences (what follows). By modifying these, they promote positive change through positive reinforcement—like praising or rewarding a desired action to make it more likely to repeat. For example, if your child melts down during transitions (e.g., from playtime to bedtime), ABA might identify sensory overload as the antecedent and teach coping strategies, reinforcing calm responses with a favorite sticker.

ABA is flexible and evidence-based, endorsed by the U.S. Surgeon General and the American Academy of Pediatrics as a “best practice” for ASD. It’s been studied for over 50 years, with applications beyond autism to conditions like ADHD, traumatic brain injury (TBI), and even anxiety disorders.
