Edwin A. Locke is an American psychologist known for pioneering goal-setting theory. He received his B.A. from Harvard University and his Ph.D. from Cornell University. Locke's goal-setting theory from 1968 proposes that specific, challenging goals along with feedback lead to higher task performance. The five principles of goal setting are that goals should be clear, challenging, committed to, receive feedback, and consider task complexity. Goal setting theory is widely used in workplaces and organizations like General Electric to improve performance.
