Kenneth Wartenbe Spence (May 6, 1907 - January 12, 1967) was a prominent American psychologist. His most prominent work was discovering Spence's Theory of Stimulus Control.
Collaborateur of Clark Hull, he was a professor at McGill University in Montreal.
Theories of Learning, A Historical Approach by John C. Malone:
Spence did his doctoral work at Yale, where his research was directed by Robert Yerkes, not by Clark Hull. Spence contributed a great deal to Hull's theory. His major contributions were his theory of discrimination learning, which is still current, his interpretation of inhibition, and his emphasis on incentive motivation rather than biological drive.
