Final answer:
The statement that intrinsic motivation reflects others' desires is false; it is driven by personal satisfaction. Carl's motivation for mowing the lawn is extrinsic because he is motivated by money. Motivation is complex and can be affected by various factors, including extrinsic rewards.
Step-by-step explanation:
The statement 'Intrinsic motivation reflects desires that others have' is false. Intrinsic motivation comes from within and is driven by personal satisfaction and fulfillment rather than by external rewards or pressures. An example of intrinsic motivation might be a person painting because they enjoy the creative process, regardless of whether they receive praise or money for their artwork.
The type of motivation Carl exhibits by mowing the yard for $20 is extrinsic motivation. He is motivated by the external reward of receiving money for the task he performs, rather than by an internal desire to mow lawns for personal fulfillment.
While motivation can be driven by either intrinsic or extrinsic factors, real-world scenarios often involve a mix. Research has shown that motivation is a nuanced concept and that the relationship between intrinsic and extrinsic motivation can be complex. Extrinsic rewards, like money, might temporarily diminish intrinsic motivation, a phenomenon known as the over-justification effect. Conversely, unexpected extrinsic rewards like verbal praise can sometimes enhance intrinsic motivation.
