Electra complex classical psychoanalytic theory, the child's identification with the same-sex parent is the successful resolution of the Electra complex and of the Oedipus complex; his and her key psychological experience to developing a mature sexual role and identity. Sigmund Freud instead proposed that girls and boys resolved their complexes differently—she via penis envy, he via castration anxiety; and that unsuccessful resolutions might lead to neurosis. Hence, women and men who are fixated in the Electra and Oedipal stages of their psychosexual development might be considered "father-fixated" and "mother-fixated". As a psychoanalytic term for daughter–mother psychosexual conflict, the Electra complex derives from
Oedipus complex difference; the other main character in the Oedipal drama becomes Tiresias (the false hypothesis erected against anxiety about a new theory)". Resultantly, "Bion regarded the central crime of Oedipus as his insistence on knowing the truth at all costs". From the postmodern perspective, Jacques Lacan argued against removing the Oedipus complex from the center of psychosexual developmental experience. He considered "the Oedipus complex—in so far as we continue to recognize it as covering the whole field of our experience with its signification ... [that] superimposes the kingdom of culture" upon the person, marking his or her introduction to symbolic order.
