Applied Behavior Analysis (ABA) is the science of behavior. ABA is the process of systematically applying evidence-based principles of the learning theory to improve socially significant behaviors to a meaningful degree (Baer, Wolf & Risley, 1968). ABA provides scientifically-supported methods for increasing positive behaviors such (e.g., language, self help skills) and for reducing problem behavior (e.g., tantrums) for individuals with Autism and related disorders.
