Final answer:
According to the drive theory of motivation, deviations from homeostasis create physiological needs. Individuals are motivated to reduce tension or stimulation to return to a state of homeostasis.
Step-by-step explanation:
According to the drive theory of motivation, deviations from homeostasis create physiological needs. These needs result in psychological drive states that direct behavior to meet the need and, ultimately, bring the system back to homeostasis.
For example, if it's been a while since you ate, your blood sugar levels will drop below normal. This low blood sugar will induce a physiological need and a corresponding drive state (i.e., hunger) that will direct you to seek out and consume food. Eating will eliminate the hunger, and, ultimately, your blood sugar levels will return to normal.
