Answer:
the premark principle
Step-by-step explanation:
In simple words, The Premack Theory suggests more likely habits will perpetuate less likely behaviours. Premack's Theory implies that if a individual wants to carry out a certain task, the individual must carry out a less acceptable task to even get to the most favourable operation; that is, actions that themselves being reinforcing. An person would be more likely to undertake a single task if he assumes as a result that he would take part in a more rewarding activity.
