Final answer:
The desire to pursue an internal goal is called intrinsic motivation, whereas pursuing a goal for external rewards is extrinsic motivation. Carl's motivation for mowing a yard for payment is extrinsic. Self-regulation is also known as will power, and a person's confidence in their abilities is termed self-efficacy.
Step-by-step explanation:
The Nature of Intrinsic and Extrinsic Motivation
The desire to pursue a goal that comes from within a person is called intrinsic motivation. Intrinsic motivation is the internal drive to do something for the sake of personal satisfaction or interest, rather than for some external reward. For instance, if you pursue an education because you enjoy learning, that is intrinsic motivation. On the other hand, extrinsic motivation refers to motivation that comes from outside the individual, such as seeking to earn money or the acclaim of others. If Carl mows the yard of his elderly neighbor for $20, this is an example of extrinsic motivation since he is being motivated by a reward. Self-regulation, which is the process of controlling one's behavior to reach a goal, is known as will power.
Your confidence in your abilities is termed self-efficacy, which is crucial for motivation. It is believed that intrinsic motivation can be diminished when extrinsic rewards are introduced, a phenomenon known as the overjustification effect.
