Some children, on the other hand, never seem to free themselves from the parent of the opposite sex. They are technically designated as the victims of a mother fixation in the case of boys, of a father fixation in the case of girls. =Jung's Interpretation.= Jung, head of the Swiss school of psychoanalysis, considers the Oedipus complication from a broader point of view. To him the father and mother are not real persons, but more or less symbolic and distorted figures created by the imagination of the child. The yearning of the child for its mother, its jealousy toward the father are simply due to its desire to monopolise a perfect provider and protector. =Pseudo-Incest.= To Adler of Vienna, the Oedipus complex is a fiction created unconsciously by the neurotic who is trying to fall back on the father or mother for support. The boy, afraid of life and of the responsibilities imposed upon a man by a normal sexual life, is naturally inclined to cling fondly to his mother, from whom he receives a love and adoration which need not be won or paid for or reciprocated and which in their demonstrativeness only stop short of sexual gratification. The neurotic girl dreams of monopolising the father's affection and financial support which are not to be repaid by sexual intercourse with its consequences, etc. Freud's interpretation explains certain details of behavior in boys with a mother fixation but the yearning to return to the mother's body does not explain a father fixation in a woman. On the other hand, Jung's explanation fails to account for some of the grossly sexual details in the behavior of the fixation child, such as great curiosity directed toward the parent of the opposite sex, at times, even, attempts on the part of a boy to possess the mother in her sleep, etc. =The Neurotic Life Plan.= Adler has clearly seen that the Oedipus situation is not the cause, but merely one of the details of the neurotic life plan. A human being adopts that plan because, owing to some inferiority, real or imaginary, (real to him), he feels unable to compete with other human beings on a footing of equality. The neurosis supplies him with a short cut to power along the line of least effort. That short cut is selfish, unsocial and, hence, productive of unpleasant results. The mother-fixation man, the father-fixation woman shirk their biological duties, thereby leading an easier, cheaper, self-centered life which, in the end, vouchsafes them no real positive gratification. What Adler has left unexplained is how the parent fixation establishes itself in the neurotic. =Imitation.= The Oedipus situation is simply one of the consequences of the imitation by the child of the parent of the opposite sex. Imitation plays a tremendous part in human life and, as far as behavior is concerned, is an infinitely more powerful factor than heredity.
