Clark L. Hull (psychologist)

Clark L. Hull was an American psychologist known for his work in learning theory and motivation. Active in the early to mid-20th century, he proposed that behavior is driven by basic needs and drives, such as hunger or thirst, which motivate individuals to take action to satisfy those needs. Hull developed the "drive-reduction theory," suggesting that behavior is aimed at reducing these drives and restoring balance. His research laid the groundwork for later theories of behaviorism and influenced fields like educational psychology and behavioral therapy. Hull's work emphasized the importance of scientific measurement in psychology.
