Applied Behavior Analysis (ABA) is a therapy based on the science of learning and behavior. It is commonly used to help individuals with autism and other developmental conditions improve specific behaviors, such as communication, social skills, academics, and daily living tasks. ABA works by breaking down complex skills into smaller steps and teaching them through positive reinforcement, repetition, and consistent practice. Therapists observe behavior, set goals, and use data to track progress and adjust techniques as needed. ABA can be provided in various settings, including homes, schools, or clinics, and it is most effective when started early and tailored to the individual's needs.
