Drive-Reduction Theory
Captions available
The idea
Drive-reduction theory holds that a physiological need creates a drive that motivates behavior to reduce it.
In practice
Fluid loss creates thirst, which motivates drinking, which ends the drive.
Where people slip
Drive reduction cannot explain behavior that increases arousal, such as seeking novelty or risk.
