Which theory states that a physiological need creates an aroused drive that motivates the organism to satisfy the need and restore homeostasis?

• A. Drive Reduction Theory
• B. Arousal Theory
• C. Instinct Theory
• D. Intuition

Answer: (A)

When a physiological need arises, the body generates an internal drive that energizes and directs behavior toward reducing that need. This drive helps restore balance, or homeostasis, by prompting actions like eating or drinking to meet the deficit. Drive Reduction Theory captures this sequence—need → aroused drive → behavior to satisfy the need and bring the system back to equilibrium. The other ideas don’t fit as neatly: arousal theory centers on seeking an optimal level of stimulation rather than satisfying a deficit; instinct theory emphasizes inherited patterns rather than current physiological states; intuition isn’t a formal motivation theory. So the description matches Drive Reduction Theory.
