Even though psychology and psychiatry share elements of psychoanalysis, all three schools of thought have unique origins; psychiatry has roots in medicine, and psychology stems from the academic study of animal and human perception. In the early 1900s, psychology was initially applied clinically as an educational aid.
In the first part of the 20th century, Sigmund Freud introduced the world to psychoanalysis, a theory which was a combination of cognitive functioning and a philosophy of mental treatment. Freud, a medical doctor and professor of medicine, molded various deals into what would become the model for psychoanalysis while performing research on hysteria and compulsion neurosis. Psychoanalysis is based on the principle that people suffer from psychological symptoms that are triggered by the unconscious avoidance of the numerous displeasing traits that we possess. A "psycho" evaluation, which may include an analysis of our train of thought and mental pictures, will provide some insight into what causes us to constantly mislead people and deceive ourselves. This treatment is said to be effective because once a person comes to grips with their own deceitfulness, then they will understand how to control it, thus reducing some of the related side effects.
To qualify as a psychoanalyst, a person must be officially educated at a psychoanalytic institution. For a period of time, psychiatrists were the only professionals allowed into psychoanalytic training facilities, and psychoanalysis was the treatment of choice for psychiatrists involved with psychotherapy. This day in age, it is not uncommon for psychologists and social workers to be granted admission to psychoanalytic training as well.
A person who finishes the classes required to become a psychoanalyst must also subject themselves to psychoanalytic treatment. Some psychologists who are disinterested in becoming ordained still participate in a personal psychoanalysis so that they can be of greater guidance to their patients.
