What principle underlies Skinner's theory of operant conditioning?

The principle underlying Skinner's theory of operant conditioning is that behavior changes occur through reinforcement and punishment. This theory posits that behaviors can be modified by their consequences; that is, if a behavior is followed by a positive reinforcement, it is likely to be repeated, while if a behavior leads to punishment or a negative outcome, it is less likely to be repeated. Skinner emphasized the role of external factors in shaping behavior, noting that systematic application of reinforcements and punishments can effectively influence individuals' actions. This concept highlights the interactive relationship between behavior and environmental stimuli, strengthening the understanding that learning and behavior modification can be profoundly influenced by the consequences that follow actions.
