Phallic stage the female aspect of phallic-stage psychosexual development as the feminine Oedipus attitude and the negative Oedipus complex; but his student–collaborator Carl Jung proposed the "Electra complex", derived from Greek mythologic character Electra, who plotted matricidal revenge against her mother for the murder of her father, to describe a girl's psychosexual competition with her mother for possession of her father. Despite mother being the parent who primarily gratifies the child's desires, the child begins forming a discrete sexual identity — "boy", "girl" — that alters the dynamics of the parent and child relationship; the parents become the focus of infantile libidinal
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.
