Defence mechanism

Goya, Los Caprichos.

In Freudian psychoanalytic theory, defence mechanisms or defense mechanisms (see -ce/-se) are psychological strategies brought into play by various entities to cope with reality and to maintain self-image. Healthy persons normally use different defences throughout life. An ego defence mechanism becomes pathological only when its persistent use leads to maladaptive behavior such that the physical and/or mental health of the individual is adversely affected. The purpose of the Ego Defence Mechanisms is to protect the mind/self/ego from anxiety, social sanctions or to provide a refuge from a situation with which one cannot currently cope.[1]

They are more accurately referred to as ego defence mechanisms, and can thus be categorized as occurring when the id impulses are in conflict with each other, when the id impulses conflict with super-ego values and beliefs, and when an external threat is posed to the ego.

The term "defence mechanism" is often thought to refer to a definitive singular term for personality traits which arise due to loss or traumatic experiences, but more accurately refers to several types of reactions which were identified during and after daughter Anna Freud's time.

Structural model: The id, ego, and superego

The concept of id impulses comes from Sigmund Freud’s structural model. According to this theory, id impulses are based on the pleasure principle: instant gratification of one’s own desires and needs. Sigmund Freud believed that the id represents biological instinctual impulses in ourselves, such as aggression (Thanatos or the Death instinct) and sexuality (Eros or the Life instinct). For example, when the id impulses (e.g. desire to have sexual relations with a stranger) conflict with the superego (e.g. belief in societal conventions of not having sex with unknown persons), the feelings of anxiety come to the surface. To reduce these negative feelings, the ego might use defence mechanisms.

Freud also believed that conflicts between these two structures resulted in conflicts associated with psychosexual stages.

The iceberg metaphor is often used to explain the psyche's parts in relation to one another.

Definitions of individual psyche structures

Freud proposed three structures of the psyche or personality:

Primary and secondary processes

In the ego, there are two ongoing processes. First, there is the unconscious primary process, where the thoughts are not organized in a coherent way, the feelings can shift, contradictions are not in conflict or are just not perceived that way, and condensations arise. There is no logic and no time line. Lust is important for this process. By contrast, there is the conscious secondary process, where strong boundaries are set and thoughts must be organized in a coherent way. Most conscious thoughts originate here.

The reality principle

Id impulses are not appropriate for civilized society, so society presses us to modify the pleasure principle in favor of the reality principle; that is, the requirements of the external world.

Formation of the superego

The superego forms as the child grows and learns parental and social standards. The superego consists of two structures: the conscience, which stores information about what is "bad" and what has been punished and the ego ideal, which stores information about what is "good" and what one "should" do or be. (Interestingly, the Freudian conscience became cognitive-behavioral therapist Albert Ellis' focus.)

The ego's use of defence mechanisms

When anxiety becomes too overwhelming it is then the place of the ego to employ defence mechanisms to protect the individual. Feelings of guilt, embarrassment and shame often accompany the feeling of anxiety. In the first definitive book on defence mechanisms, Ego and mechanisms of defense (1936), Anna Freud introduced the concept of signal anxiety; she stated that it was "not directly a conflicted instinctual tension but a signal occurring in the ego of an anticipated instinctual tension". The signaling function of anxiety is thus seen as a crucial one and biologically adapted to warn the organism of danger or a threat to its equilibrium. The anxiety is felt as an increase in bodily or mental tension and the signal that the organism receives in this way allows it the possibility of taking defensive action towards the perceived danger. Defence mechanisms work by distorting the id impulses into acceptable forms, or by unconscious blockage of these impulses.

Categorization of Defence Mechanisms

Level 1 Defence Mechanisms

The mechanisms on this level, when predominating, almost always are severely pathological. These three defences, in conjunction, permit one to effectively rearrange external reality and eliminate the need to cope with reality. The pathological users of these mechanisms frequently appear crazy or insane to others. These are the "psychotic" defences, common in overt psychosis. However, they are found in dreams and throughout childhood as healthy mechanisms.

They include:

Level 2 Defence Mechanisms

These mechanisms are often present in adults and more commonly present in adolescence. These mechanisms lessen distress and anxiety provoked by threatening people or by uncomfortable reality. People who excessively use such defences are seen as socially undesirable in that they are immature, difficult to deal with and seriously out of touch with reality. These are the so-called "immature" defences and overuse almost always lead to serious problems in a person's ability to cope effectively. These defences are often seen in severe depression and personality disorders. In adolescence, the occurrence of all of these defences is normal.

These include:

Level 3 Defence Mechanisms

These mechanisms are considered neurotic, but fairly common in adults. Such defences have short-term advantages in coping, but can often cause long-term problems in relationships, work and in enjoying life when used as one's primary style of coping with the world.

These include:

Level 4 Defence Mechanisms

These are commonly found among emotionally healthy adults and are considered the most mature, even though many have their origins in the immature level. However, these have been adapted through the years so as to optimize success in life and relationships. The use of these defences enhances user pleasure and feelings of mastery. These defences help the users to integrate conflicting emotions and thoughts while still remaining effective. Persons who use these mechanisms are viewed as having virtues.

These include:

Other theories and classifications

The list of particular defence mechanisms is huge and there is no theoretical consensus on the number of defence mechanisms. Classifying defence mechanisms according to some of their properties (i.e. underlying mechanisms, similarities or connections with personality) has been attempted. Different theorists have different categorizations and conceptualizations of defence mechanisms. Large reviews of theories of defence mechanisms are available from Paulhus, Fridhandler and Hayes (1997) and Cramer (1991).[3][4] Also, the Journal of Personality (1998) published a special issue on defence mechanisms.[5]

Otto Kernberg (1967) has developed a theory of borderline personality organization (which one consequence may be borderline personality disorder). His theory is based on ego psychological object relations theory. Borderline personality organization develops when the child cannot integrate positive and negative mental objects together. Kernberg views the use of primitive defence mechanisms central to this personality organization. Primitive psychological defences are projection, denial, dissociation or splitting, and they are called borderline defence mechanisms. Also, devaluation and projective identification are seen as borderline defences.[6]

In George Eman Vaillant's (1977) categorization, defences form a continuum related to their psychoanalytical developmental level.[7] Vaillant's levels are:

Robert Plutchik's (1979) theory views defenses as derivatives of basic emotions. Defence mechanisms in his theory are (in order of placement in circumplex model): reaction formation, denial, repression, regression, compensation, projection, displacement, intellectualization.[8]

The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) published by the American Psychiatric Association (1994) includes a tentative diagnostic axis for defence mechanisms.[9] This classification is largely based on Vaillant's hierarchical view of defences, but has some modifications. Examples include: denial, fantasy, rationalization, regression, isolation, projection, and displacement.
