Martavis has two choices for his Friday evening activity. He can either go to a party with some friends, or he can stay home and study for an important exam on Monday. The first option offers a lot of immediate fun, but the second option means he won't have to waste his entire Saturday and Sunday studying. In deciding which outcome he will prefer, Martavis is weighing the of each of his options.

In deciding which outcome he will prefer, Martavis is weighing the reinforcement values of his options.

Explanation:

In psychology, reinforcement value refers to the perceived pleasure something will give us. If an action is pleasing or appealing, we will want to do it again, which means it has a high reinforcement value.

In Martavis's case, going to a party obviously seems to have a higher reinforcement value than studying. However, when he thinks that studying this Friday evening will mean more free time throughout the weekend, he perceives a higher value to this action. His choice, in the end, will be the activity that he perceives as more valuable, more appealing.
