A theory is as an idea or a set of ideas that are intended to explain facts or events. The beginning of the twentieth century saw the birth of two new theories. The psychoanalytic theory and behaviorism became the two general theories of psychology. Originating from Sigmund Freud, the psychoanalytic theory contends that the root of human behavior starts with unconscious thoughts and internal debates. The first six years of life are divided into three stages of development - the oral stage, the anal stage, and the phallic stage. Freud further stated that two more developmental periods follow in early childhood. There is latency and the genital stage. Freud characterized each stage with a sexual nature. He did not believe that there were any new stages
