OEDIPUS COMPLEX

in psychoanalytic theory, a desire for sexual involvement with the parent of the opposite sex and a concomitant sense of rivalry with the parent of the same sex; a crucial stage in the normal developmental process. Sigmund Freud introduced the concept in his Interpretation of Dreams (1899). The term derives from the Theban hero Oedipus of Greek legend, who unknowingly slew his father and married his mother; its female analogue, the Electra complex, is named for another mythological figure, who helped slay her mother. Freud attributed the Oedipus complex to children of about the ages three to five. He said the stage usually ended when the child identified with the parent of the same sex and repressed its sexual instincts. If previous relationships with the parents were relatively loving and nontraumatic, and if parental attitudes were neither excessively prohibitive nor excessively stimulating, the stage is passed through harmoniously. In the presence of trauma, however, there occurs an infantile neurosis that is an important forerunner of similar reactions during the child's adult life. The superego, the moral factor that dominates the conscious adult mind, also has its origin in the process of overcoming the Oedipus complex. Freud considered the reactions against the Oedipus complex the most important social achievements of the human mind.
