Clark Leonard Hull was an American psychologist who developed an influential theory of behaviour in which he identified the variables that intervene between stimulus and response. He made experimental studies on learning, that he presented in his book, Aptitude Testing (1928) and attempted to structure psychological theory following a deductive method of reasoning similar to that used in geometry. He proposed that from a set of postulates about psychology, logical conclusions could be deduced and tested. Hull was the first known psychologist to apply quantitative experimental methods to the investigation of hypnosis. His last books were Essentials of Behavior (1951) and A Behavior System (1952).
