Final answer:
O need In drive reduction theory, a 'need' is something that causes a drive which motivates behavior to fulfill that need and restore balance within the body.
Step-by-step explanation:
In drive reduction theory, a need is a deprivation that energizes the drive to eliminate or reduce that deprivation. This concept is based on the idea that deviations from homeostasis create physiological needs that lead to psychological drive states. These drive states then prompt behavior aimed at meeting the need and restoring homeostasis. For example, hunger is a drive that motivates you to eat, thereby returning blood sugar levels back to normal. As habits form regarding behaviors that successfully reduce drives, these become our go-to responses when similar needs arise.
In drive reduction theory, a need is a deprivation that energizes the drive to eliminate or reduce that deprivation. This theory suggests that deviations from homeostasis create physiological needs, which result in psychological drive states that direct behavior to meet the need and bring the system back to homeostasis. For example, feeling hungry (the deprivation) will create a drive to seek out and consume food in order to reduce the hunger.
