Which scenario is an example of the Premack Principle?

The Premack Principle refers to a concept in psychology where a more preferred behavior is used to reinforce a less preferred behavior. In this context, it suggests that engaging in a high-frequency behavior can be made contingent upon engaging in a low-frequency behavior, effectively motivating the individual to complete the less desirable task.

In the scenario provided, where Kevin must clean his room before he is allowed to play video games, the act of playing video games is considered a more preferred or enjoyable activity compared to cleaning the room. Thus, by using the privilege of playing video games as a reward for completing the less enjoyable task of cleaning, this scenario exemplifies the Premack Principle effectively. It captures the essence of reinforcing a less preferred behavior (cleaning) by linking it to a more preferred behavior (playing video games).

The other scenarios do reflect conditions of delayed gratification or task completion, but they don't specifically highlight the concept of using a preferred activity as a motivator for completing a less preferred one in the same way.
