Final answer:
The answer is true. The drive theory of motivation asserts that behaviors driven by physiological needs should diminish once those needs are met and homeostasis is restored.
Step-by-step explanation:
According to the drive theory of motivation, drives are created when there are deviations from homeostasis. These drives result in psychological drive states that prompt behavior aimed at fulfilling a physiological need, which brings the body back to a state of homeostasis. When this balance is restored, and the physiological need is met, the associated behavior that arose from the drive is expected to diminish as the drive has been satisfied. For instance, hunger drives you to eat, and once you've eaten enough, your hunger diminishes. This happens because your blood sugar levels return to normal, reducing the drive that initiated the eating behavior.
Therefore, the answer to the student's question of whether behavior should diminish once drives are reduced and homeostasis is restored is true. The reduced drive no longer motivates the behavior, leading to a decrease in the actions that were originally driven by the need to restore balance within the body's system. This is also supported by the fact that once we engage in a behavior that successfully reduces a drive, we are likely to repeat that behavior in the future when faced with the same drive—an effect of habit formation.
