Which of the following is a disadvantage of relying too much on extrinsic motivation?

Focusing too heavily on extrinsic motivation can lead to a reduction in intrinsic interest in an activity. When individuals frequently receive rewards or external recognition for their efforts, they may start to associate their participation in the task primarily with these external rewards rather than with the inherent enjoyment or satisfaction derived from the activity itself. This shift can diminish their intrinsic motivation, which is the internal drive to engage in an activity for its own sake, not for a reward. As a result, when the external rewards are removed or become less frequent, individuals may lose their motivation to engage in the task altogether.

In contrast, options that refer to increased creativity, enjoyment of tasks, or the development of self-discipline do not directly address the potential negative impact of excessive reliance on external rewards. While these aspects can be beneficial in certain contexts, they do not pertain to the specific disadvantage of over-relying on extrinsic motivation, which is the core of the question.
