David Premack, a professor of psychology came with Premack principle which says that a highly desirable activity should be used as reinforcement for less desirable activity ex. if you want your child to study ( least desirable activity), then you should use ice cream ( highly desirable activity) as reinforcement, so you child gets ice cream only when he completes his studies.
This principle, with minor variations, is used in corporate world. A person is made to do lot of tasks which all hate to do with promise of promotion or pay hike. General theme is ” I know you don’t like ….but if you want to grow ( i.e. get promotion in next appraisal)…. then…”
This “if…then” statements are examples of Premack Principle.
