Lateralization of defence mechanisms in a visual half-field paradigm

A percept-genetic test of defence mechanisms (the Meta-Contrast Technique) was given to 169 undergraduate students. Subjects were divided into three groups: two visual half-field groups and one group tested in the regular way. It was hypothesized that the visual field groups would differ from one another and from the control group. An ANOVA showed that the left and right visual half-field conditions differed significantly, as hypothesized. Clear regressive signs were more common in the left visual half-field group, whereas isolation and repression were more common in the right. Furthermore, the visual half-field conditions differed in certain respects from the control group. It was concluded that processes in both hemispheres are important for complex psychological functions.     

Defence strategies and anxiety in mothers of disabled children

The aim of this investigation was to study anxiety and defence strategies in mothers of children with different disabilities. Mothers of children with childhood psychosis, motor handicaps, or Down's syndrome were tested with a projective, percept-genetic technique, viz. the Mother-Child Picture Test (MCPT). Levels of anxiety were measured with the Hospital Anxiety and Depression Scale (HAD). In mothers of psychotic children, the absence of anxiety was significantly associated with misinterpretations and/or failure to recognize the MCPT motif (a close relation between mother and child). This association was not found in the mothers of motor-handicapped children or children with Down's syndrome. The results suggest that, for mothers of psychotic children, the activation of defensive strategies is important to avoid feelings of anxiety evoked by the mother-child situation. For mothers of children with other chronic disabilities, for example, motor handicaps or Down's syndrome, low levels of anxiety may be experienced without the mobilization of strong defensive mechanisms. Different interpretations of the correlation between defence strategies and anxiety in the mothers of psychotic children are discussed.     

Percept-genetic signs of repression in histrionic personality disorder.

Several types of perceptual distortions of two anxiety-arousing visual stimuli are coded as repression in the Defense Mechanism Test, a tachistoscopic, percept-genetic technique. Given the well-established correspondence between hysteria and repression, the study included a clinical validation of these variants of repression against the diagnosis of histrionic personality disorder. 41 subjects with evidence of this disorder on the Millon Clinical Multiaxial Inventory-II were compared with 41 nonhistrionic controls. Significantly more histrionics were coded for the type of repression in which the threatening figure is transformed into a harmless object (code 1:42), while animal- and statue-repressions, when combined (codes 1:1 and 1:2), were significantly more characteristic of the nonhistrionic group. As an unpredicted finding, significantly more histrionic subjects employed defensive strategies, currently coded as reaction formations (code 4:). Histrionic subjects without concomitant compulsive features were coded more frequently for introaggression (code 6:) compared both with nonhistrionic controls and with histrionic-compulsive subjects. The findings are discussed within the context of the available percept-genetic literature. It is suggested that the Defense Mechanism Test may be further employed to objectify and investigate the defense mechanisms of the DSM-III-R disorders.     

Defense mechanisms and coping strategies in conjugal relationships: An integration

Coping strategies and defence mechanisms are used to describe people's responses to stressful situations. The concept of coping strategies comes from the social psychological tradition, whereas the concept of defence mechanisms comes from the psychoanalytic tradition. According to the traditional view, the two concepts are very different. However, recently, a growing number of researchers suggested that coping strategies and defence mechanisms are more interrelated than what was assumed previously. This study was aimed at documenting the relationship between both concepts in the context of predicting adjustment in a specific situation, marital relationships, one of the most well‐suited situations to investigate people's responses to stressful situations. The sample consisted of 157 couples. Each partner completed the Ways of Coping Questionnaire, the Defense Style Questionnaire, and the Dyadic Adjustment Scale. Two theoretical models, the independence model and the effectiveness model, accounting for the relationship between coping strategies and defence mechanisms were first tested, using confirmatory factor analyses. According to the independence hypothesis, one latent dimension should measure defence mechanisms and the other latent dimension should measure coping strategies. According to the effectiveness hypothesis, coping strategies and defence mechanisms could vary along two dimensions: adaptive and maladaptive ways of dealing with marital difficulties. Results revealed that the effectiveness hypothesis was a better representation of the relationship between the two concepts than the independence hypothesis. The unique contribution of defence mechanisms and coping strategies to the prediction of marital adjustment was next examined using multiple regression analyses. Again, results were generally congruent with the effectiveness hypothesis. Positive and negative relationships with marital adjustment were observed for both concepts. In addition, coping strategies did not result in more positive outcomes on marital adjustment than defence mechanisms. It seems that coping strategies and defence mechanisms have both their specificity and their shared characteristics.     

Lay understandings of defence mechanisms: The role of personality traits and gender

This study looks at lay people's knowledge and use of the defence mechanisms. It focused on 21 of the better known "Freudian" defence mechanisms. A total of 208 participants (73 males and 135 females) completed a questionnaire regarding their knowledge and reported personal use of 21 defence mechanisms and a short personality test. Participants were required to state (1) whether they had heard of each mechanism, (2) how common they believed it to be and (3) whether they themselves used each of them. The defences were categorised into four levels: Pathological, immature, neurotic and mature. Two personality traits (Openness and Neuroticism) positively correlated with two of the levels but few gender or age correlations were identified. Regression analysis showed that Neuroticism predicted the three less mature defence levels; Gender was a contributing predictor of a pathological defence style and Openness and religiosity combined with Neuroticism predicted an immature defence style. Participants admitted using the more socially acceptable (mature) defences (i.e. humour, intellectualisation) than the less acceptable (pathological) defences (i.e. distortion, hypochondriasis). Implications for psychotherapy are discussed and the limitations of the study considered.     

Avoiding unbearable pain

This presentation describes the way in which defence mechanisms and resistance manifested themselves in the analysis of a man with a narcissistic personality disorder. In the course of the analysis, there were changes in the forms taken by the defence and the resistance, signalling important genetic and dynamic conditions in his life. Both represented desperate attempts to avoid the unbearably painful feelings and affects which he had experienced in his childhood, and bore witness to early and primitive defence mechanisms such as denial, splitting and projective identification. The defence can also be seen as an expression of an unconscious fear of being re-traumatised. The idealisation of the analyst in the first years of the analysis can therefore be understood as a precondition for entering into this kind of process. It also represented a defence against aggressive and homosexual feelings in the transference which first became clear during the final phase of the analysis and could then be worked through. At this point, the analyst's reactions to his own unconscious countertransference were of help in understanding what was actually going on. This analysis may also suggest that defects and trauma in the earliest years may be conducive to alexithymia, deficient contact between feelings and words, linked to the risk of developing serious psychosomatic illnesses. This may be a consequence of the fact that the child's feelings and affects were neither accepted, understood nor affirmed in words, or they may even have been met with rejection or ridicule. A connection between narcissistic personality disorders and alexithymia can possibly be seen here.     

Deducing the Mind

Frank Jackson has argued that, in principle, all mental truths are deducible from all physical science truths: 'deducibility'. Jackson's defence of deducibility relies upon the method for producing naturalistic definitions of mental states championed in the analytical functionalism of himself, David Lewis, and others. Two arguments are presented. The first contends that the particular naturalistic definitions of analytical functionalism fail because they do not take account of the extraordinary kind of bodily animation displayed by human beings, which I argue is necessary to (at least one kind of) mentality; machines lacking (at least this one kind of) mentality can satisfy the naturalistic definitions of analytical functionalism. So Jackson's defence of deducibility fails as it stands. The second argument contends that no naturalistic conceptual analysis of the mental can be adequate, because understanding (certain) mental concepts requires a special kind of affective reaction here named 'personal response', while understanding naturalistic concepts does not require this- therefore no naturalistic analysis can ever capture our common-sense mental concepts. The upshot is that Jackson's defence of deducibility cannot be repaired. No defence of deducibility will work which relies upon the possibility of naturalistic conceptual analyses of mentality.     

Creativity and anxiety: An experimental study

Tested a group of 31 psychiatric patients with anxiety as one of their main symptoms using a percept-genetic (PG) test measuring creativity or willingness to reconstruct subjective interpretations of the stimulus. A control group of 43 from an earlier study was also included. For half of the subjects a threatening motif was presented subliminally during part of the PG series. By means of an interview, an estimation was made of the subjects' urge to create and of the severity of their anxiety. The Meta-Contrast Technique (MCT) was used to describe defenses in the clinical group. Taking into account their urge to be creative, the clinical subjects received relatively few positive scores on the PG test. The subliminal addition to the anxiety level did not facilitate creative functioning as was the case with the normal subjects. The main obstacles to creative functioning seemed to be grave anxiety and rigid defense mechanisms or, to generalize, low tolorance of the anxiety necessarily associated with creative work.     

Method for examining children's beliefs about the functional role played by defensive interpersonal behaviour

The goal of this study was to develop a method for examining children's expectations about the short‐term consequences of defensive interpersonal behaviour. We employed the theory of interpersonal defence (Dahmen & Westerman, in press; Westerman, 1998, 2005 ; Westerman & Prieto, 2006 ), an interpersonal reconceptualization of defence processes, as the framework for this method. We developed a two‐part procedure for eliciting children's responses to closed‐ended and open‐ended questions about interpersonal vignettes presented in storyboard format, and we employed this method in a preliminary investigation with a sample of 62 intellectually gifted boys and girls aged 7–8 and 10–11. The results showed that the participants understood that defensive interpersonal behaviours affect the likelihood that feared and wished‐for short‐term outcomes will occur. Participants demonstrated that they understood that people behave defensively in order to avoid feared consequences and nondefensively in order to pursue wished‐for outcomes. Findings also indicated that older participants understood that a person is more likely to behave defensively in highly conflict‐ridden situations. The results suggest that our method provides the basis for research that complements previous studies of children's understanding of how intrapsychic defence mechanisms regulate a person's affective experience. Future research using this method could investigate the role of beliefs about defensive behaviour in the development of behaviour problems.     

Lateralization of defence mechanisms related to creative functioning

Eighty-four undergraduate students were randomly divided into left and right visual half-field groups. They were tested in either visual half-field with a percept-genetic test of anxiety and defense mechanisms (the MCT). The subjects also took a test of creative functioning (the CFT) and degree of lateralization in the MCT was related to level of creativity in the CFT. Subjects low in creativity were significantly lateralized on measures typical for the right visual half-field group (isolation and repression) and tended to differ on a left visual half-field measure (regressive strategies). For high creative subjects no differences were found between the visual half-field groups. Also, high creative persons more often responded with non-hemisphere-specific defenses than low creative ones. The results were interpreted as due to differing levels of transmission of information between the two hemispheres of the brain.     

Multivariate modelling and personality organization: A comparative study of the Defense Mechanism Test and linguistic expressions

The main aim of the study is to establish an empirical connection between perceptual defences as measured by the Defense Mechanism Test (DMT)–a projective percept-genetic method–and manifest linguistic expressions based on word pattern analyses. The subjects were 25 psychiatric patients with the diagnoses neurotic personality organization (NPO), borderline personality organization (BPO) and psychotic personality organization (PPO) in accordance with Kernberg's theory. A set of 130 DMT variables and 40 linguistic variables were analyzed by means of partial least squares (PLS) discriminant analysis separately and then pooled together. The overall hypothesis was that it would be possible to define the personality organization of the patients in terms of an amalgam of perceptual defences and word patterns, and that these two kinds of data would confirm each other. The result of the combined PLS analysis revealed a very good separation between the diagnostic groups as measured by the pooled variable sets. Among other things, it was shown that NPO patients are principally characterized by linguistic variables, whereas BPO and PPO patients are better defined by perceptual defences as measured by the DMT method.     

An aggression machine I. The intensity of aggressive defence aroused by aggressive offence

PitkÄnen, L. An aggression machine. I. The intensity of aggressive defence aroused by aggressive offence. Scand. J. Psychol., 1973, 14, 56–64.-Sixty 9-year-old boys were tested with an aggression machine (PAM) designed by the writer. PAM allows the variation of both S (light) and R (pressing a button) intensities. The stimuli and responses were given the designations of offensive and defensive aggression, respectively. The following main hypotheses were supported: (1) The intensity of impulsive aggressive defence to an aggressive offence was adapted to the intensity of attack. (2) The intensity of aggressive defence was determined by the authority of the attacker, the defence being strongest when the attacker was a person of the same age and status, and least vigorous when the attacker was a figure of authority or a weaker person. (3) The correlations of the intensity of aggressive defence against different attackers depended on the similarity of their social position; the correlations were higher the closer the position.     

The Defence Mechanism Test (DMT) revisited: experimental validation using threatening and non‐threatening pictures

Although the Defence Mechanism Test (DMT) has been in use for almost half a century, it is still unclear what it actually measures. The psychodynamic theory on which the test is based states that the threatful DMT pictures activate various defence mechanisms. To test this proposition, the original DMT pictures were redrawn by a professional artist, changing the emotional content without altering the structural properties. In this way, a neutral and a friendly variant were shaped. Sixty participants were randomly assigned to the threatful, neutral, and friendly stimulus conditions. In contrast to predictions made from psychodynamic theory, that the threatful picture would activate more ‘signs of defence’ than the others, the results disclosed that the three conditions activated the same amounts of ‘signs of defence’ and the same levels of various perceptual thresholds. Thus, rather than capturing psychodynamic defence mechanisms, our results suggest that the DMT taps perceptual or information‐processing difficulties in correct identification of brief stimulus exposures regardless of their emotional contents.

Mania, loss and defense: a percept-genetic investigation.

The defensive organization of manic states has been investigated with the Defense Mechanism Test-Separation Theme. A black and white stimulus portraying a mother figure who is leaving an infant alone was presented tachistoscopically, at increasing durations of exposure, to 22 inpatients who had had a manic episode and to 22 age- and sex-matched normal controls. The manic group was characterized by the following six major defense codings: (1) the infant is able to walk or run, (2) the mother is a rigid, inanimate being, (3) the mother is veiled or disguised, (4) the mother is protective or inviting, (5) the mother is seen as a male figure, and (6) colors are perceived in the colorless stimulus. Controls were more often coded for the denial of mother's actions (she enters the room, she opens a window, etc). The findings were discussed in the context of the pertinent percept-genetic and psychoanalytic literature.     

The role of psychological defences in moderating between trauma and post‐traumatic symptoms among Palestinian men

Psychological defences are conceptualized as protective processes that help individuals to maintain their integrity in the face of threat and danger. Accordingly, their role in defending trauma victims from post‐traumatic symptoms was examined. The sample consisted of 128 Palestinian male political ex‐prisoners who had reported various degrees of torture and ill‐treatment. The first aim was to analyze the dimensionality and distribution of different defence mechanisms. The second was to examine which defences would moderate the association between the reported torture and ill‐treatment and the post‐traumatic symptoms (PTS). Third, the direct associations between reported torture and ill‐treatment and defences and between the defences and symptoms were explored. Defence mechanisms were assessed by a 40‐item version of the Defense Style Questionnaire (DSQ), and Post‐traumatic symptoms by the Harvard Trauma Questionnaire (HTQ), and experiences of torture and ill‐treatment by a scale developed for that purpose. The results show, first, that the men used predominantly mature defences such as anticipation, sublimation, suppression, and rationalization, but also relatively frequently somatization and dissociation, which are characteristic responses among trauma victims. Second, the principal component analysis revealed four defence dimensions, differentiated by the level of maturity and the approach to reality: the mature reality‐based, the consciousness‐limiting, the immature reality‐escaping, and the immature reality‐distorting defences. Third, against our hypothesis, the moderating analyses indicated that the reported torture and ill‐treatment were relatively more associated with vigilance, avoidance, and intrusion symptoms if men used consciousness‐limiting defences. Yet as expected, the mature reality‐based defences did not show a protective effect. Furthermore, a high level of reported torture and ill‐treatment was associated with a low level of the mature reality‐based defences, but not with a high level of immature defences. Last, similarly to earlier studies, the immature reality‐distorting and immature reality‐escaping defences associated directly with high, and mature reality‐based defences with low, levels of PTS‐symptoms.     

Resolving defence mechanisms: A perspective based on dissipative structure theory

Theories and classifications of defence mechanisms are not unified. This study addresses the psychological system as a dissipative structure which exchanges information with the external and internal world. When using defence mechanisms, the cognitive‐affective schema of an individual could remain stable and ordered by excluding psychological entropy, obtaining psychological negentropy or by dissipating the energy of self‐presentation. From this perspective, defences can be classified into three basic types: isolation, compensation and self‐dissipation. However, not every kind of defence mechanisms can actually help the individual. Non‐adaptive defences are just functioning as an effective strategy in the short run but can be a harmful approach in the long run, while adaptive defences could instead help the individual as a long‐term mechanism. Thus, we would like to suggest that it is more useful for the individual to use more adaptive defence mechanisms and seek out social or interpersonal support when undergoing psychic difficulties. As this model of defences is theoretical at present, we therefore aim to support and enrich this viewpoint with empirical evidence.     

The psychogenesis of the ego: notes on Freud's 'case of homosexuality in a woman'

This paper examines Freud's (1920) case study 'The psychogenesis of homosexuality in a woman' in the light of the second topography that was being elaborated in his theoretical writing at that time. The analysis of the ego and its defence mechanisms, which was to become such an important part of clinical technique in Anglo-American psychoanalysis, psychoanalytic psychotherapy and psychodynamic counselling, is not set out explicitly in any of Freud's case studies. However, in this last case study presented by Freud, it is possible to see how an attention to family dynamics, Oedipal structures and patterns of identification set the stage for the new notion of the ego to emerge. This 'turning point' in theory and clinical technique is also, in this case, intimately related to theories of sexuality, and Freud's own assumptions about homosexuality and heterosexuality are considered here in relation to his account of the ego.     

Counselling of alcohol-dependents based on a model of change to abstinence

A model of change to abstinence in alcohol-dependents is presented based on the theory of reasoned action of Ajzen & Fishbein. The model includes attitudes, defence mechanisms and norms about aspects of alcohol consumption. An empirical study supports elements of the model. Conclusions pertinent to the counselling process are drawn.     

Reactions to DMT as related to psychotic and borderline personality organization

Thirty-one inpatients in a psychiatric clinic were assessed with DMT and the Structural Interview. In order to assemble every relevant reaction that an individual might have to a percept-genesis, 130 DMT variables were formed. The results were first subjected to a quality control of the DMT-scores and then subjected to partial least squares in latent variables (PLS) discriminant analysis. The analysis showed that it is possible to separate patients with psychotic PO (PPO) from those with borderline PO (BPO) by means of the 130 variables. The BPO group is characterized by aggressive manifestations, sensitivity to threat, identity lability and various transformations of the Hero gestalt. The PPO group, on the other hand, is characterized by high threshold values for perception, lack of identity, denial and repression of the peripheral person at a late-phase level. There are other perceptual reactions that are important predictors of PO than the defence categories of the manual. These perceptual reactions do not correspond to the traditional psychodynamic defence mechanisms. Our conclusion is that principal component analysis (PCA) and PLS are useful methods of finding discriminating patterns of perceptual reactions to the DMT for patients with different PO.
