13. Which person is demonstrating delay of gratification?

Answer: D

Explanation:

D) A person who refuses social invitations in order to study for their exams

This individual exemplifies delay of gratification by prioritizing long-term academic success over immediate social enjoyment. By choosing to study instead of attending social events, they are demonstrating self-control and a commitment to their future goals.

A) A person who knows they excel in their chosen field of study

While this person has confidence in their abilities, their situation does not illustrate delay of gratification. They are not making a choice between immediate pleasure and long-term benefits; rather, they are simply aware of their strengths.

B) A person who knows that if they go to a game today, they can study later for an exam

This person is not demonstrating delay of gratification since they plan to study later after attending the game. The ability to postpone studying does not reflect the same level of self-discipline as outright refusing social activities to focus on studying.

C) A person who was unsure if they would have the discipline to study in college

Doubt about one's discipline does not equate to demonstrating delay of gratification. This individual does not exhibit the behavior of prioritizing long-term goals over immediate desires, as they are still contemplating their ability to act on such choices.

D) A person who refuses social invitations in order to study for their exams

This option clearly represents delay of gratification, as the individual is actively choosing to forego immediate social interactions to focus on their studies. This decision underscores their commitment to achieving academic success, showcasing effective self-control.

Conclusion

The correct choice, D, highlights the concept of delay of gratification through a clear decision to prioritize long-term academic goals over immediate social rewards. Options A, B, and C do not illustrate this principle as they involve either confidence, planning without commitment, or uncertainty, which do not reflect the self-discipline required for delaying gratification.
