Psychological Defense Mechanisms: A New Perspective

Approaching psychological defense mechanisms from the perspective of an evolved strategy, it is proposed that there are two basic templates-dissociation and cognitive distortions. Frequently conceived of as pathological, these psychological phenomena actually constitute overlapping spectrums with milder manifestations being common and highly functional, and more severe variants less common and typically dysfunctional. Dissociation provides the capacity to adaptively detach from disturbing emotional states, and cognitive distortions place a positive ego-enhancing spin on experience. Most of the classical defense mechanisms described in the psychoanalytic literature represent a form of cognitive distortion with some containing strong elements of dissociation.     

Defensiveness and Defense Mechanisms

This introduction to the Journal of Personality's special issue on the topic of defense mechanisms raises the question of why defenses have been largely overlooked in personality research. Although defenses were originally discussed in the context of psychopathology, for the past 60 years psychodynamically oriented psychologists have understood that defenses play an important part in normal psychological development. Recently, psychologists outside the field of personality have incorporated the ideas of unconscious mental processes and of defenses into their research programs. In this issue, personality researchers discuss their ideas about defense mechanisms, organized around three topical areas: current conceptualizations of defense, the measurement of defense mechanisms, and the integration of defense mechanisms into personality research. The issue concludes with a commentary on these articles and provides suggestions for future work.     

The Development of Defense Mechanisms

ABSTRACT It is proposed that defense mechanisms may be characterized as forming a hierarchy, from least to most complex, and that the lowest level defenses emerge early in life, while the more complex defenses emerge later in development Three defenses–Denial, Projection and Identification–were chosen to test this assumption A method for assessing the use of these defenses in Thematic Apperception Test (TAT) stories was developed and validated in a study of four age groups preschool, elementary school, early adolescent, and late adolescent The results of the study were consistent with the prediction Denial was used most frequently by preschool children, and decreased in use thereafter Identification was used minimally by preschool children but increased steadily through adolescence The use of Projection was most frequent in the two middle age groups Some evidence for sex differences, based on the internal/external orientation of the defense, also was found     

Observer-Rated Measures of Defense Mechanisms

Observer-rated measures of defense mechanisms are the direct lineal descendants of Freud's clinical proposition that an observer can reasonably infer defensive operations in an individual of which the individual himself or herself is unaware. Assessment methods of defenses have used both projective testing and clinical interview data. Recent Rorschach test methods have focused on borderline and neurotic-level defenses used to discriminate diagnostic groups and predict other aspects of functioning. A TAT method has demonstrated some evidence for age progression in the development of defensive functioning and for regression in defensive functioning following psychological stress. While interrater reliability is generally good, the methods are limited by the availability of the testing situation and the need to demonstrate generalization to external situations.
Following the early introduction of systematic methods by Haan and Vaillant, a number of methods use clinical interview data to assess specific defenses and overall defensive functioning. These methods identify defenses either as qualitative categories, rank-ordered scores by Q-sort, or actual counts of each instance a defense is used. Summary scores are generally of good reliability, with wider variation for individual defenses. There is wide variation on training required, ease of use, and levels of validation.
A review of some correlates of each method suggests that the instruments have a robust potential for use in fundamental and applied clinical research. While each method has some clear applications, the quantitative clinical interview methods appear best adapted to microanalytic process research on issues of defensive change in treatment.     

Immunizing Strategies and Epistemic Defense Mechanisms

An immunizing strategy is an argument brought forward in support of a belief system, though independent from that belief system, which makes it more or less invulnerable to rational argumentation and/or empirical evidence. By contrast, an epistemic defense mechanism is defined as a structural feature of a belief system which has the same effect of deflecting arguments and evidence. We discuss the remarkable recurrence of certain patterns of immunizing strategies and defense mechanisms in pseudoscience and other belief systems. Five different types will be distinguished and analyzed, with examples drawn from widely different domains. The difference between immunizing strategies and defense mechanisms is analyzed, and their epistemological status is discussed. Our classification sheds new light on the various ways in which belief systems may achieve invulnerability against empirical evidence and rational criticism, and we propose our analysis as part of an explanation of these belief systems’ enduring appeal and tenacity.     

This I Have Learned from Over 40 Years of Personality Research

ABSTRACT During the over 40 years in which I have conducted personality research, I have had a number of insights about the research process that I thought would be worth sharing: an awareness of the human side of science; lessons from the person-situation debate; lessons from comparing research on highly ego-involving natural events, such as sport parachuting, with laboratory analogues; the realization of what is wrong with the concept of the Freudian unconscious and what should be done to replace it; and awareness of pervasive biases in the journal-reviewing process. Perhaps the one most general lesson I have learned is that the advancement of psychology as a cumulative, integrative science is hampered not so much by its conceptual complexity as by the difficulty of humankind to view itself objectively, with honesty, courage, and a willingness to surrender illusions.     

Personality, Personality Disorders, and Defense Mechanisms

The prototype approach was used to assess the presence of personality features associated with borderline, narcissistic, histrionic, and psychopathic personality syndromes in a sample of 91 young adults from the Block and Block (1980) longitudinal study. These personality prototypes were found to be related to the use of denial and projection, and especially to the immature manifestations of those defenses, in ways consistent with theory.     

Reliability of an Idiographic Q-Sort Measure of Defense Mechanisms

Despite the important insights the concept of defense mechanisms may offer to our understanding of human behavior, no standardized definitions of defense mechanisms have been universally accepted. Inconsistencies in the definition and conceptualization of defense mechanisms has limited the practical utility of research involving these constructs. In addition, lack of interrater reliability, use of anecdotal evidence, and reliance on self-reports has retarded their investigation. Conducting methodologically rigorous investigations with a psychometrically sound instrument is the first step in addressing some of the issues concerning defense mechanisms and their theoretical postulates. This study was conducted to determine the reliability associated with the Defense-Q, an observer-based Q-sort measure of defense mechanisms. Thirty participants who had undergone an interpersonally stressful interview (the Type A Structured Interview; Rosenman, 1978) were rated by 11 trained coders, both for their use of the 25 defense mechanisms and for their ego strength. Reliability was assessed using Cronbach's alpha. Individual defense mechanisms demonstrated reliability ranging from .28 (undoing) to .92 (humor), with an average reliability of .73. Coder reliability ranged from .63 to .76, with an average of .69. These results indicate that defense mechartisms can be reliably assessed by the Defense-Q. Reliability of the Defense-Q is compared to existing observational measures of defense mechanisms.     

The Identification and Modification of Defense Mechanisms in Counseling

This article suggests considerations and strategies for identifying and modifying a client's defense mechanisms in counseling. A systematic approach to a client's mechanisms of defense contributes to therapeutic gain. Inappropriate counselor responses intensify an individual's defenses and undermine the counseling relationship. Definitions of individual defenses and indicators for identifying the mechanisms are provided. A literature review focuses on the counseling implications of the defenses. The process of defense mechanism modification is illustrated through a case example.     

Evidence for Change in Children's Use of Defense Mechanisms

ABSTRACT Using a cohort-longitudinal design, children's use of the defeneses of denial. projection, and identification was assessed at four points over a 2-year time span, covering the age period from 6 years, 6 months to 9 years, 5 months. The results showed a clear decrease in the use of denial from early to middle childhood, a sharp increase in the use of projection, and an increase in the use of identification. These findings, predicted by a theory of defense mechanism development, are consistent with cross-sectional results reported previously.     

Resilience in Holocaust Survivors: A Study of Defense Mechanisms in Holocaust Narratives

There is extensive literature examining the psychological adaptation of survivors after the Holocaust, including studies of Holocaust narratives (HN). As a measure of psychological adaptation, defense mechanisms (DM) have been studied in various clinical samples, however, to date, not in Holocaust narratives. Using a standardized observer-rated measure, we assessed DM in Holocaust versus pre/post Holocaust narratives (other narratives [ON]) in 20 in-depth survivor interviews. Regarding individual DM, isolation of affect and self-assertion were statistically more frequent in the HN than the ON. High adaptive (mature) level defenses were more frequent in the HNs than the ON. Furthermore, the overall defensive functioning (ODF) was higher in the HN than the ON, contradicting previous findings showing lower defensive functioning in life-threatening situations. Possible explanations include differences in the nature of trauma, the time elapsed between the trauma and the interview, and the specificity of the sample. A qualitative overview with several examples from the narratives are also presented.     

Attributional Style and Psychodynamic Defense Mechanisms: Toward an Integrative Model of Depression

The present study examined the influences of cognitive style and psychodynamic defense mechanisms in accounting for levels of dysphoria. Measures of dysphoria, defense mechanisms, and attributional style were completed by 147 undergraduate students. Consistent with the hypothesis, both attributional style and principalization were independently associated with dysphoria. Moreover, principalization moderated the influence of attributional style on levels of dysphoria. In addition, attributional style and turning against self were independently associated with dysphoria. Turning against other, projection, and reversal were not associated with dysphoria. The results provide partial support for the notion that the applicability and validity of the hopelessness theory of depression are bolstered by a consideration of psychodynamic phenomena. Potential implications of this line of research for the movement toward psychotherapy integration are discussed.     

Disturbed Children's and Adolescents' Comprehension of Psychological Mechanisms of Defense

This study examined the role of Piagetian logical and analytical reasoning in the comprehension of psychological defense mechanisms among 26 emotionally disturbed boys. Participants assigned to one of three Piagetian cognitive stages, listened to vignettes depicting defensive behaviors of various degrees of logical and structural complexity. Results indicated that, although both within- and between-group performances were at variance with theoretical expectations, consistent age trends in the comprehension of defense mechanisms were observed.     

The Relationship Between Emotional Intelligence and Ego Defense Mechanisms

The author examined the relationship between the components of emotional intelligence (perception of emotion, affect regulation, and emotional knowledge) and personality factors associated with adaptation, represented by the hierarchical model of defense mechanisms (M. Bond, S. Gardner, J. Christian. & J. Sigal, 1983). Bivariate correlation analyses yielded mixed results; the adaptive defense styles were correlated with overall emotional intelligence but not with the emotional perception and regulation components, as was hypothesized. Emotional knowledge was correlated with both adaptive and maladaptive defense styles and with general intelligence, as was expected. Implications for counseling and psychoeducational interventions are suggested.     

Predicting Psychiatric Symptomatology with the Defense Style Questionnaire-40

The relationship between specific defense styles and symptom-related responses was investigated in a large sample of university students. In general, immature defenses were the major predictors of the symptom patterns measured by the Brief Symptom Inventory. In particular, combinations of projection, displacement, autistic fantasy, somatization, and acting out were the strongest predictors of psychopathology. Projection was a major predictor of psychopathology in males, whereas displacement was the major predictor for females. Several similarities and differences in the relationship between defense styles and different disorders were revealed.;or timing of both psychological and hormonal responses to 2 given volumes of training.     

Anger and the Use of Defense Mechanisms in College Students

ABSTRACT It was hypothesized that experimentally induced anger would result in an increased use of defense mechanisms in college students. As predicted from the theory of defense mechanism development, the Thematic Apperception Test (TAT) stories of angered students showed a higher level of use of projection and identification, and the use of these defenses was significantly correlated with the presence of aggressive content in the stories. The results were consistent with previous studies in showing that the predominant defenses of late adolescents are projection and identification, and that men use more projection than women.
