If one activity occurs more often than another, it can be used to reinforce the activity that occurs less often. This principle is known as :

Question

Accepted Answer

Premack's principle is the correct answer because it directly addresses the use of high-probability behaviors to reinforce low-probability behaviors.

*   **Why Option 1 (Premack's principle) is correct:** Premack's principle, also known as the relativity theory of reinforcement, states that more probable behaviors will reinforce less probable behaviors. In simpler terms, a preferred activity can be used to motivate someone to perform a less preferred activity. The question describes this exact scenario: a more frequent activity (high-probability behavior) is used to reinforce a less frequent activity (low-probability behavior). For example, if a child enjoys playing video games more than doing homework, playing video games (the more frequent, preferred activity) can be used as a reward for completing homework (the less frequent, less preferred activity).

*   **Why Option 2 (Thorndike's principle) is incorrect:** Thorndike's most famous contribution is the Law of Effect, which states that behaviors followed by satisfying consequences are more likely to be repeated, and behaviors followed by unpleasant consequences are less likely to be repeated. While reinforcement is involved, Thorndike's principle focuses on the consequence of a behavior influencing its future occurrence, not on using one behavior to reinforce another based on their relative frequencies.

*   **Why Option 3 (Skinner's principle) is incorrect:** Skinner is known for his work on operant conditioning, which involves reinforcement and punishment to shape behavior. While Skinner's work is related to reinforcement, it doesn't specifically address the use of high-probability behaviors to reinforce low-probability behaviors. Skinner's principles are broader, encompassing various schedules of reinforcement and types of consequences.

*   **Why Option 4 (Pavlov's principle) is incorrect:** Pavlov is famous for his work on classical conditioning, which involves associating a neutral stimulus with a naturally occurring stimulus to elicit a conditioned response. This type of learning is about associations between stimuli, not about using one behavior to reinforce another. Classical conditioning is fundamentally different from the concept described in the question.
