Oedipus complex
Initially, Freud equally applied the Oedipus complex to the psychosexual development of boys and girls, but later developed the female aspects of the theory as the feminine Oedipus attitude and the negative Oedipus complex; yet, it was his student–collaborator, Carl Jung, who coined the term Electra complex in 1913. Nonetheless, Freud rejected Jung's term as psychoanalytically inaccurate: "that what we have said about the Oedipus complex applies with complete strictness to the male child only, and that we are right in rejecting the term 'Electra complex', which seeks to emphasize the analogy between the attitude of the two sexes".
