Final answer:
Motivation can be classified as intrinsic or extrinsic. Intrinsic motivation is driven by internal satisfaction, while extrinsic motivation is influenced by external goals and rewards.
Step-by-step explanation:
The statement presents the concept of external goals and how they motivate behaviors. It highlights a classification of motivation into two broad categories: intrinsic and extrinsic. Intrinsic motivation comes from within the individual due to personal satisfaction or interest, while extrinsic motivation comes from outside factors or rewards.
For example, Carl mowing his neighbor's lawn for $20 is motivated by extrinsic factors, specifically the monetary reward, which is an external goal. Conversely, if Carl mowed the lawn because he found the activity itself rewarding or satisfying, that would be an intrinsic motivation.
