Clark Hull

Clark Hull was a influential American psychologist known for his work on understanding human motivation and behavior. He believed that our actions are driven by biological needs, like hunger or thirst, which create internal drives or pressures. These drives motivate us to act in ways that satisfy those needs, such as eating or drinking. Hull also emphasized the importance of learning through habits and reinforcement—rewards or punishments that shape future behavior. His theories aimed to explain how and why we behave the way we do, combining biological and psychological factors in a systematic way.
