Drive-Reduction Theory: Push Theory of Motivation

Clark Hull introduced the drive-reduction theory, often called the push theory of motivation.

This theory explains how biological drives such as hunger or sleep emerge from imbalances or unmet needs, prompting behavior aimed at restoring balance.

According to Hull, motivation arises from the need to reduce physiological tension caused by unmet biological needs.

For instance, the absence of a fundamental biological necessity, like water, motivates an individual to fulfill that need.

This theory also introduces the idea of homeostasis, which refers to the body's natural inclination to keep its internal environment stable and balanced.

For instance, when body temperature rises due to external heat, it begins sweating to cool down, restoring temperature to its optimal range, reducing physiological stress, and, as a result, maintaining homeostasis.

This theory suggests that there are two types of drives. The primary drives relate to basic survival needs like hunger and thirst.

The second, acquired or secondary drives, are learned through experience and conditioning. Fulfilling these drives often leads to positive reinforcement, such as gaining approval or rewards like money.
