The mechanisms of defense indicate, in Psychanalyse, the processes used by the Me from the adaptive point of view.
Ego defends oneself especially against the anguish.
The individual unconsciously sets up means to deform reality and to reject certain emotions except conscience. Thus, a mechanism of defense is then used to decrease the anxiety or depresses it felt by this last; it thus relieves temporarily.
Generally, their use is banal, flexible and normal. One sees their contribution to the character traits then. However, a rigid use, unsuited to the situations and constant characterizes the personality disorders then.
The mechanism of defense, such as it is initially theorized, applies to unconscious Représentation S. In this case, the Symptom which form is Compromise-formation (or " Reaction-formation ")between the conscious desires and the unconscious desires.
Among the normal symptoms , let us quote the Rêve, the Lapsus the parapraxes.
But certain mechanisms imply on the contrary a failure of the Refoulement. The concept of defense extends beyond the register from the neurosis. According to the psychoanalysis, a mechanism can mean a more or less massive, and more or less harmful defense for the subject which employs it.
Among defenses, sublimation occupies a particular status, since it does not require repression. A conscious impulse can find sublimation. It thus is not about a defense strictly speaking.
The Sublimation is one of the four destinies of the impulse at Freud. It is thus not a mechanism of defense of ego strictly speaking.
Primal repression: one antiquated time of the history of the subject, bearing inaugural repression on a particularly awkward representation (seduction by an adult, images of the primitive scene…) without this representation not becoming conscience. This primary education repression determines to some extent the future orientation of other repressions.
repression itself: it consists of a double movement. On the one hand, primary education repression attracts the representations which are close for him and on the other hand, the authorities interdictrices (Super-ego combined with Ego) push back these representations in the Inconscient.
return of the repressed: the representations which were driven back in the Inconscient can bind between them. On the occasion, certain representations - deteriorated, disguised - can reappear in the conscious one in the form of dreams or phantasms (a traditional and salutary return of driven back made possible by the need for a valve), under the form of Lapsus or parapraxes, and finally, in the form of symptoms then announcing the failure of the process of repression.
It is Sigmund Freud which in 1894 described for the first time the operation of this mechanism of defense. The insulation makes it possible to completely separate the representation of the Affect, which is found free. The private representation of any association can then remain in the conscious one. The insulation, as well as other mechanisms, is with work after the failure of a repression.
In certainly a way, this defense of the Primary process with work in is very manifest content and conscious. For example, the somatic Conversion in the hysterical Névrose is a specific displacement of an affect on the body. Repression is then partly missed because the symbolic system of this symptom makes it possible to go up by the process of Régression until the representation inconsiliable and driven back.
Displacement is the mechanism of defense privileged in the Obsessional neurosis (or neurosis of constraint) where the sexual representation inconsiliable is substituted for another on the associative ways (even Associationisme or English Empirisme).
This instinctual destiny thus modifies the object of the impulse in the clean person.
It is also called aggression-passive.
The inversion in its opposite is another instinctual destiny, with repression, the inversion on the clean person and sublimation. The original impulse is then reversed on the level of its goal.
Recall of the determinants of the Impulse: Source, Push, Goal and Object.
Example: Sadism in masochism, retention in expension…
The energy used in the anticathexis of another representation in the GCV is that which pushed the representation driven back initially; it was thus reinvested (moved) on another representation, which one calls the anticathexis.
The invested representation of energy resulting from repression, will become a substitute representation, in the case of the conversion hysteria (by investment of a body representation), just like of the phobia (by the substitute formation) or an obsessional neurosis (by the reaction-formation).
Freud gives a particularly relevant example of it: a neurotic reports to him that he dreamed of a woman. He says more to remember the identity of this woman, but to be certain in any case who it is not a question of her mother. Such a compromise-formation at the same time is denied a representation (incestueux dream) and reveals it.
Nevertheless, from many different identifications are distinguished by Freud itself.
To open the field, there is also the “mimetic Désir” of the model-obstacle of Rene Girard who claims to face Freud on the ground of the desire and Marx on that of the value.
The representation of a struck desire of interdict is driven back in the Inconscient. Only point of view of the pleasure principle, there thus exists a lack that the Me will try to compensate, which it will do in substituent with this initial Représentation of a desire, another representation which discreetly (by the means of associations of ideas) will evoke the initial desire. This mechanism is for example with work at the time of fright mystical: seemingly, it there has nothing sexual in this demonstration but is however preserved a Affect related to the sexual pleasure. It is one of the modes of return of the repressed (see low “Repression”).
The compromise-formation constitutes it also a mode of return of the repressed but this last will be sufficiently deformed not to be recognized. There will be compromising between the unconscious desires (interdicts) and prohibitions. This mechanism is particularly apparent in the dreams, in certain symptoms (the systematic need for a counter-phobic object), like in certain artistic works.
Vis-a-vis certain conflituelles relations, the subject seeks to solve the conflict while returning to a early Stade. Its Libido will turn over at a stage where it had found a Gratification.
Mechanism describes by Sándor Ferenczi and Anna Freud. Its most banal expression is found in the childish plays: to play the wolf, doctor… To become that which makes fear makes it possible to remove it. They are in the case evoked “a simple” inversion the roles. This mechanism can be more radical and consist of a true introjection of the dangerous object.
For example, in the case of the Fetishism, the fetishist is cleaved: part of itself recognizes the Angoisse of castration, another part does not recognize it.
The splitting of the ego is characterized, in the psychosis, by the multitude of personalities which it generates, result extremely different from the Dédoublement of personality.
The neurotic, it is necessary to admit, has recourse to the splitting of the ego, but in a way largely less marked. Isn't repression, resulting in the formation from unconscious which does not communicate with the conscious one, a form of cleavage?
Mechanism of defense identified and described by Melanie Klein and which is with work during the schizo-paranoid Position. The child projects himself fantasmatiquement inside the mother to exert his absolute power there (it also fantasmée): possession even destruction of the body of the mother, controls objects previously projected in the mother (penis of the father, other children…). It is necessary that the mother, on an unconscious level, can accept this type of phantasm. If a rigid interdict is posed by the mother against these phantasms, there will be réintrojection in the child of partial objects and threatening (worrying center, avid vagina) - as many objects which will impoverish the Me.
