Premack principle
Explanation:
The premack principle states that am individual will engage in less probable behaviour so that he can engage in more probable behavior. In essence the more probable behaviour or activity reinforces the less probable behaviour or activity. Parents use this very often to make their children engage in more positive and beneficial activities by making them do those beneficial activities first before doing their(the child) preferred activities.
