Premack Principle
The reinforcement principle that high-probability behaviors can reinforce low-probability behaviors.
Full Definition
The Premack Principle states that behaviors occurring at high frequencies can serve as reinforcers for behaviors occurring at lower frequencies, often summarized as "Grandma's Law" (first eat your vegetables, then you can have dessert). This principle expands the concept of reinforcement beyond tangible items to include preferred activities and behaviors. In behavioral medicine, the Premack Principle is applied to increase adherence to medical regimens by linking required health behaviors with naturally occurring, preferred activities. This approach is particularly useful when traditional reinforcers are limited or when working with individuals who have restricted interests.
Usage
Usage note: Emphasize the activity-based nature of reinforcement rather than tangible rewards.
