Sigmund Freud of Vienna, who is considered as the father of modern psychology, originated a new method called the Free Association Technique. Freud considered that mind has three parts  the conscious, the pre-conscious and the unconscious. He considered that 90% of the mind is the unconscious mind.
John Watson was an American psychologist who is considered the father of the psychological school of behaviorism. Behaviorism, according to Watson, was the science of observable behavior. In the fledgling field of psychology, this was a new idea that went against Freud and popular theories about the subconscious, which Watson felt were too subjective.
