Eric Berne was a Canadian-born psychiatrist who, in the middle of the 20th century, created the theory of transactional analysis as a way of explaining human behavior. Berne’s theory of transactional analysis was based on the ideas of Freud but were distinctly different.
Freudian psychotherapists focused on talk therapy as a way of gaining insight to their patient’s personalities. Berne believed that insight could be better discovered by analyzing patients’ social transactions.
Berne was among the first psychiatrists to apply game theory to the field of psychiatry, along with the famed psychiatrist-psychoanalyst Thomas Szasz.
