Which of the following interventions is based on Skinner's Operant Conditioning theory?

Applied Behavior Analysis (ABA) is indeed based on Skinner's Operant Conditioning theory, which emphasizes the role of reinforcement and punishment in shaping behavior. This approach focuses on modifying specific behaviors through systematic observation and intervention strategies that reinforce desired behaviors while discouraging undesirable ones.

In ABA, the use of positive reinforcement is particularly crucial; when a desirable behavior is exhibited, it is followed by a reward, which increases the likelihood that the behavior will occur again in the future. Conversely, undesirable behaviors are addressed through various strategies that can include the use of less reinforcement or structured environments to redirect the behavior.

ABA is widely applied in numerous contexts, particularly in working with individuals with autism, helping them develop functional communication and social skills, manage behaviors, and improve overall learning outcomes. This alignment with Skinner's principles forms the foundation of ABA, making it the most direct representation of operant conditioning among the choices provided.

Other options, while valuable in their own contexts, do not focus primarily on behavior modification through reinforcement and punishment as outlined by Skinner’s theory.
