The approach to motivation that forced psychologists to consider the value of homeostasis in motivation was the __________ approach.

A) arousal
B) drive-reduction
C) instinct
D) incentive

The drive-reduction approach focuses on the idea that a physiological need creates a drive or urge to satisfy that need, and when the need is satisfied, a state of balance or homeostasis is achieved. This approach highlights the value of homeostasis in motivation. The arousal approach emphasizes the role of an organism's level of arousal, and the incentive approach focuses on environmental stimuli that motivate behavior. The instinct approach suggests that behavior is innate and genetically programmed.
