Behavior Analysis is a scientific discipline that focuses on understanding and modifying behavior through the principles of behaviorism. It examines how environmental factors influence actions and reactions, emphasizing observable behaviors rather than internal thoughts or feelings. Practitioners of behavior analysis often use techniques such as Applied Behavior Analysis (ABA) to promote positive behavior changes, especially in settings like education and therapy. This approach is widely used to support individuals with autism spectrum disorder and other developmental challenges, helping them improve communication, social skills, and daily living activities.
