David McClelland

David McClelland was an American psychologist best known for his work on motivation and personality. He developed the Theory of Needs, which identifies three primary motivations: the need for achievement, the need for affiliation, and the need for power. McClelland believed that these needs influence how people behave and perform in various contexts, such as work and relationships. His research emphasized the importance of understanding these motivations to foster individual development and improve organizational effectiveness. His ideas are widely applied in fields like education, business, and psychology to enhance motivation and productivity.
