What principle suggests that a behavior will be more likely repeated if followed by a reward?

The principle suggesting that a behavior will be more likely repeated if followed by a reward is known as the Law of Effect. This principle was originally formulated by Edward Thorndike, who conducted experiments with cats and put them in puzzle boxes. Thorndike observed that behaviors followed by satisfying outcomes (or rewards) were more likely to be repeated in similar situations, while behaviors that led to unsatisfactory outcomes were less likely to occur again.

The Law of Effect emphasizes the connection between behavior and consequences, highlighting that positive outcomes reinforce certain behaviors, making them more habitual over time. This concept laid the groundwork for further developments in behavioral psychology, particularly in understanding how rewards can shape actions. While positive reinforcement, operant conditioning, and stimulus-response theory are related concepts in behavioral psychology, the Law of Effect specifically articulates the principle regarding the increased likelihood of repeating behaviors that are rewarded.
