Premack Principle: A Guide to Understanding Motivation

The Premack principle states that a person will perform a less preferred activity (low probability behavior) to gain access to a more preferred activity (high probability behavior). A less preferred activity is defined as one in which the individual is unlikely to choose to do on their own, thus developing the term low probability behavior. A more preferred activity is an activity that the individual would likely choose to engage in on their own, a high probability behavior.
