<P> Psycho - logic defense--In both sexes, defense mechanisms provide transitory resolutions of the conflict between the drives of the id and the drives of the ego . The first defense mechanism is repression, the blocking of memories, emotional impulses, and ideas from the conscious mind; yet its action does not resolve the id--ego conflict . The second defense mechanism is identification, in which the boy or girl child adapts by incorporating, to his or her (super) ego, the personality characteristics of the same - sex parent . As a result of this, the boy diminishes his castration anxiety, because his likeness to father protects him from father's wrath in their maternal rivalry . In the case of the girl, this facilitates identifying with mother, who understands that, in being females, neither of them possesses a penis, and thus are not antagonists . </P> <P> Dénouement--Unresolved son--father competition for the psycho - sexual possession of the mother might result in a phallic stage fixation that leads to the boy becoming an aggressive, over-ambitious, and vain man . Therefore, the satisfactory parental handling and resolution of the Oedipus complex are most important in developing the male infantile super-ego . This is because, by identifying with a parent, the boy internalizes Morality; thereby, he chooses to comply with societal rules, rather than reflexively complying in fear of punishment . </P> <P> In Analysis of a Phobia in a Five - year - old Boy (1909), the case study of the equinophobic boy "Little Hans", Freud showed that the relation between Hans's fears--of horses and of his father--derived from external factors, the birth of a sister, and internal factors, the desire of the infantile id to replace father as companion to mother, and guilt for enjoying the masturbation normal to a boy of his age . Moreover, his admitting to wanting to procreate with mother was considered proof of the boy's sexual attraction to the opposite - sex parent; he was a heterosexual male . Yet, the boy Hans was unable to relate fearing horses to fearing his father . As the treating psychoanalyst, Freud noted that "Hans had to be told many things that he could not say himself" and that "he had to be presented with thoughts, which he had, so far, shown no signs of possessing". </P> <P> Initially, Freud equally applied the Oedipus complex to the psychosexual development of boys and girls, but later modified the female aspects of the theory as "feminine Oedipus attitude" and "negative Oedipus complex"; yet, it was his student--collaborator Carl Jung, who, in 1913, proposed the Electra complex to describe a girl's daughter--mother competition for psychosexual possession of the father . </P>
