Which psychological theory supports the motivation suggested by researchers focusing on homeostasis?

• A. Incentive theory
• B. Drive theory
• C. Expectancy-value theory
• D. Self-determination theory

Answer: (B)

Drive theory is rooted in the concept of homeostasis, which refers to the body's need to maintain a stable internal environment. According to this theory, individuals are motivated to act in ways that restore balance when they experience physiological needs or drives, such as hunger, thirst, or discomfort. When an individual's internal state deviates from its optimal level, this creates a drive that compels them to engage in behaviors aimed at fulfilling that need and returning to homeostasis.

For example, when someone feels hungry, the drive theory suggests that this internal state will motivate them to seek food to alleviate that hunger and restore balance. This connection between physiological drives and behavior underlines the drive theory's emphasis on homeostasis as a vital factor in understanding motivation. Other theories like incentive theory, expectancy-value theory, and self-determination theory focus more on external rewards, anticipated outcomes, or intrinsic motivations, which do not directly address the physiological aspects of homeostasis in the same way.
