Sigmund Freud was the founder of psychoanalysis (1916-1917). He was a Viennese physician, being the most famous people of the early psychologist. Also, he was one of the first scientists to make a serious research of the mind. Freud had done an experiment on his own self which included studying his own dreams, memories and personality, which determined that he had many mental disorders and fears.
The psychoanalysis was the importance of unconscious motives and internal conflicts in determining and understanding human behavior. Through consultations with patients to encourage them to talk through their problems was a method that helped him gain his understandings of human behavior. The method was later called a "talking cure." The goal of this method was to release the powerful emotional energy in which he believed was locked in the unconscious mind.
Another way Freud would search the cases of mental and emotional problems were by studying the dreams of people. Asking have you ever tried to figure out the meaning of a dream you had. He believed dreams serve to gratify unconscious wishes and longings. To ease troubled minds of patients he tried hypnosis on them. The effects were only temporary. This method just involved sitting with his patients and listening to them talk.
