Applied Behavior Analysis (ABA)


ABA is the study of using the principles of behavior to change "socially important behaviors" (Bear, Wolf and Risley, 1968).  ABA creates enriched environments that support appropriate behaviors and discourage inappropriate behaviors by using antecedent and consequence strategies. ABA therapy applies our understanding of how behavior works in real situations. The goal of ABA is to increase behaviors that are helpful and  decrease behaviors that are harmful or affect learning. Positive reinforcement is one of the main strategies used in ABA.

When a behavior is followed by something that is valued a person is more likely to repeat that behavior. Over time, the positive reinforcement encourages positive lasting behavior changes.

 Baer, Wolf, and Risley (1968, 1987)  specified these seven ABA dimensions: Applied • Behavioral  • Analytical  

• Generalized  • Effective  • Technological and • Conceptually Systematic
