Extrinsic motivation refers to engaging in an activity to earn external rewards or to avoid negative consequences rather than for the inherent enjoyment or satisfaction derived from the activity itself. Winning a prize is a classic example of extrinsic motivation, as the individual is motivated by the tangible reward associated with their performance, rather than the activity itself.
In contrast, enjoying the process of learning, feeling accomplished after a task, and self-satisfaction all point toward intrinsic motivation, where the drive comes from within, based on personal growth, fulfillment, or the inherent pleasure of the activity itself. Thus, winning a prize distinctly illustrates extrinsic motivation, making it the correct choice.
