In the model of motivation, all organisms are motivated to maintain physiological equilibrium around an optimal set point, the ideal, fixed setting of a particular physiological system.

drive reduction

Explanation:

The Drive Reduction Model When our physiological systems are out of balance or depleted, we are driven to reduce this depleted state (Hull, 1943; McKinley et al., 2004; Strombach et al., 2016; Weisinger et al., 1993). Recall that a drive is the perceived internal state of tension that arises when our bodies are lacking in some basic physiological capacity, such as food or water. Central to drive reduction is Page 350the idea of maintaining physiological balance, or homeostasis
