Which of the following is an example of intrinsic motivation?

Intrinsic motivation refers to engaging in a behavior or activity for the inherent satisfaction or enjoyment derived from it, rather than for some external reward or pressure. Playing an instrument for enjoyment exemplifies intrinsic motivation because the individual finds personal pleasure and fulfillment in the act of playing, regardless of any outside factors or recognition. This intrinsic satisfaction drives the behavior, leading to sustained engagement and personal growth in the activity.

In contrast, the other options highlight forms of motivation that are influenced by external factors. Studying for an exam can sometimes be driven by the desire to achieve a good grade or pass a course, showing more extrinsic factors at play. Completing tasks for rewards clearly indicates an external incentive that motivates the behavior. Seeking approval from others also demonstrates a reliance on external validation, rather than an internal desire to engage in the activity for its own sake. Thus, playing an instrument purely for enjoyment captures the essence of intrinsic motivation effectively.
