Drive reduction theory (learning theory)

Drive reduction theory, developed by Clark Hull in 1943, is a major theory of motivation in the behaviorist learning theory tradition. "Drive" is defined as motivation that arises due to a psychological or physiological need. It works as an internal stimulus that motivates an individual to sate the drive. It has also been described as an internal and instinctual process that moves individuals to take actions that would allow them to attain their desired goal or end-state. Simply put, drive reduction theory suggests that when humans experience a physiological or psychological need, such as reducing hunger or boredom, they feel a drive to satisfy that need.
