Applied Behavior Analysis (ABA) is a methodology that applies behavioral principles to foster the development of various skills such as communication, daily living abilities, and social interaction. It relies on scientifically validated techniques to understand how environmental factors influence behavior. One key principle of ABA is Positive Reinforcement, which posits that behaviors followed by rewards are more likely to recur. In ABA therapy, children receive abundant positive reinforcement for demonstrating desired skills and socially appropriate behaviors aligned with their objectives. ABA adopts a goal-oriented approach, prioritizing positive interactions and enjoyable learning experiences. It emphasizes skill development through methods such as positive reinforcement, motivation, repetition, and visual aids in the naturalistic enviroment.
