The proposition that one activity can be used as reward to perform another activity. Thus, according to this principle, an activity that an athlete likes to do can be used as a reinforcer for an activity that the athlete is less willing to do. For example, a coach might reward footballers who complete a session of hard physical training with a five-a-side game of football. The footballers are enticed to engage in a less desired activity (hard physical training) by the opportunity to engage in a more desired activity (a game of football). In formal terms, the Premak principle states that if a high-probability action is made contingent on a low-probability action, the high-probability action will act as a reinforcers on the low-probability one.
