Further Distinctions between Coping and Defense Mechanisms?

In the current literature there is a great confusion between coping and defense mechanisms. As Cramer (1998) points out, a distinction between them is both possible and worthwhile in that they possess different cognitive features. Cramer proposes two basic criteria: the conscious/unconscious and the intentional/unintentional nature of the processes. We focus on a further criterion, the manipulation versus revision of one's mental attitudes, which so far has been neglected in the relevant literature. We suggest that responses to adversity implying manipulation are typical of defense mechanisms, while those implying the revision of one's mental attitudes characterize coping strategies. Finally, we address emotion-focused coping as the area where coping and defense meet, and we suggest that responses displaying defensive features should be excluded from the category of coping in accordance with the distinctions identified.     

Coping and Defense Mechanisms: What's the Difference?

Defense mechanisms and coping strategies are discussed as two different types of adaptational processes. They may be clearly differentiated on the basis of the psychological processes involved, but not on the basis of their relation to outcome measures. Criteria that critically differentiate between defense and coping processes include the conscious/unconscious status and the intentional/nonintentional nature of the processes. Criteria based on the dispositional or situational status of the process, and on the conceptualization of the processes as hierarchical, are found to be more a matter of emphasis than of critical difference. A criterion that attempts to differentiate between defense and coping processes on the basis of their relation to psychological or physical health is found to be without support once the bias in self-report outcome measures is recognized.     

Words and Drugs: Same Mechanisms of Action?

The therapeutic effects of words, rituals and, more in general, of the whole psychosocial context around the patient, have been investigated over the past few years by using the placebo response as a model. Today we are in a good position to study all these complex psychological factors by using a physiological and neuroscientific approach that uses modern neurobiological tools to probe different brain functions. Since a placebo is represented by the whole ritual of the therapeutic act, the main concept that has emerged today is that words and rituals may modulate the same biochemical pathways that are modulated by drugs. Most of our knowledge about these mechanisms comes from the field of pain, and represents a biomedical, psychological and philosophical enterprise that is changing the way we approach and interpret medicine, psychology and human biology. If on the one hand we know some of the mechanisms of drug action in the central nervous system, on the other we can now understand how the therapist’s words may affect different physiological functions. In fact, the placebo effect and the therapist–patient relationship can be approached by using the same biochemical, cellular and physiological tools of the materia medica. Although the responses to the therapist’s words cannot be reduced merely to the action of a single drug, this represents an epochal transition, in which the distinction between psychotherapy and pharmacotherapy is progressively getting thinner, and which helps us overcome the old dichotomy between psychology and biology.     

Mechanisms of perceptual timing: Beat-based or interval-based judgements?

Summary What is the nature of the human timing mechanism for perceptual judgements about short temporal intervals? One possibility is that initial periodic events, such as tones, establish internal beats which continue after the external events and serve as reference points for the perception of subsequent events. A second possibility is that the timer records the intervals produced by events. Later, the stored intervals can be reproduced or compared to other intervals. A study by Schulze (1978) provided evidence favoring beat-based timing. In contrast, our two experiments support an interval theory. The judgements of intervals between tones is not improved when the events are synchronized with internal beats established by the initial intervals. The conflict between the two sets of results may be resolved by the fact that an interval timer can recycle from one interval to the next, thus operating in a beat-like mode. However, a timer of this sort is just as accurate when comparing intervals that are off the beat.     

Mechanisms of motivation–cognition interaction: challenges and opportunities

Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral Neuroscience provides a sampling of some of the latest research from a number of these different areas. In this introductory article, we provide an overview of the current state of the field, in terms of key research developments and candidate neural mechanisms receiving focused investigation as potential sources of motivation–cognition interaction. However, our primary goal is conceptual: to highlight the distinct perspectives taken by different research areas, in terms of how motivation is defined, the relevant dimensions and dissociations that are emphasized, and the theoretical questions being targeted. Together, these distinctions present both challenges and opportunities for efforts aiming toward a more unified and cross-disciplinary approach. We identify a set of pressing research questions calling for this sort of cross-disciplinary approach, with the explicit goal of encouraging integrative and collaborative investigations directed toward them.     

Why Should We Lower Our Defenses About Defense Mechanisms?

Personality and social psychologists already use ideas that are closely related to defense mechanisms, but few of our paradigms include extensive theoretical or empirical treatment of such mechanisms. Yet defense mechanisms focus on negative affect and protection of the self, and many of the controversies, issues, and impasses contemporary researchers confront also concern negative affect and self-protection. This article discusses whether we might find systematic consideration of defense mechanisms and defensive processing to be broadly useful across several related areas of personality and social psychology in which the relationships between self and affect are implicated. Areas considered include positive illusions and adaptation, the interpretation of reports of negative affect, and related concepts from the coping, self-regulation, affect regulation, and goals literature. Thinking about defense mechanisms would seem to have both specific value for sharpening our understanding of different possible interpretations of our data, and broad heuristic value for thinking about personality integration and social behavior.     

Men's and Women's Mating Preferences: Distinct Evolutionary Mechanisms?

Have men and women evolved sex-distinct mating preferences for short-term and long-term mating, as postulated by some evolutionary theorists? Direct tests of assumptions, consideration of confounds with gender, and examination of the same variables for both sexes suggest men and women are remarkably similar. Furthermore, cross-species comparisons indicate that humans do not evidence mating mechanisms indicative of short-term mating (e.g., large female sexual skins, large testicles). Understanding human variability in mating preferences is apt to involve more detailed knowledge of the links between these preferences and biological and chemical mechanisms associated with sexual motivation, sexual arousal, and sexual functioning.     

Missing Data Mechanisms and Homogeneity of Means and Variances–Covariances

Unless data are missing completely at random (MCAR), proper methodology is crucial for the analysis of incomplete data. Consequently, methods for effectively testing the MCAR mechanism become important, and procedures were developed via testing the homogeneity of means and variances–covariances across the observed patterns (e.g., Kim & Bentler in Psychometrika 67:609–624, 2002; Little in J Am Stat Assoc 83:1198–1202, 1988). The current article shows that the population counterparts of the sample means and covariances of a given pattern of the observed data depend on the underlying structure that generates the data, and the normal-distribution-based maximum likelihood estimates for different patterns of the observed sample can converge to the same values even when data are missing at random or missing not at random, although the values may not equal those of the underlying population distribution. The results imply that statistics developed for testing the homogeneity of means and covariances cannot be safely used for testing the MCAR mechanism even when the population distribution is multivariate normal.     

Inspired by Mary Jane? Mechanisms underlying enhanced creativity in cannabis users

Previous research suggests cannabis may enhance some aspects of creativity, although the results remain somewhat equivocal. Moreover, it is unclear whether differences in cannabis users’ personalities may account for any potentially beneficial effects of cannabis on creativity. This study was designed to examine whether sober cannabis users demonstrate superior self-reported and objective creativity test performance relative to non-users, and to determine whether any of the Big 5 personality domains underlie these effects. A sample of sober cannabis users (n = 412) and non-users (n = 309) completed measures of cannabis consumption, personality, self-reported and objective creativity. Relative to non-users, sober cannabis users self-reported higher creativity, and performed significantly better on a measure of convergent thinking. Controlling for cannabis users’ higher levels of openness to experience abolished these effects. Therefore, while cannabis users appear to demonstrate enhanced creativity, these effects are an artifact of their heightened levels of openness to experience.     

Cognitive Mechanisms in Human Creativity: Is Variation Blind or Sighted?

It is argued that the cognitive mechanisms in human creativity are, for the most part, sighted rather than blind. The article opens with a review of attempts to apply evolutionary ideas to psychology. It continues with an argument that blind-variation ideas seem to apply well in some areas of psychology, but that the psychology of human creativity is not one of these areas. An alternative sighted-variation framework is then proposed. It is argued, nevertheless, that the blind-variation system of biological evolution itself shows emergent creative properties, even though this system does not serve as an appropriate model for human creativity.     

Mechanisms,Experiments, and Theory-Ladenness: A Realist–Perspectivalist View

The terms “perspectivism” and “perspectivalism” have been the focus of an intense philosophical discussion with important repercussions for the debate about the role of mechanisms in scientific explanations. However, leading exponents of the new mechanistic philosophy have conceded more than was necessary to the radically subjectivistic perspectivalism, and fell into the opposite error, by retaining not negligible residues of objectivistic views about mechanisms. In order to remove this vacillation between the subjective-cultural and the objective-natural sides of mechanisms, we shall raise the question about theory-ladenness over again and interpret it in its connection with the technical–experimental nature of scientific knowledge, as affirming the perspectival character of scientific knowledge: It is because of the character at once theory-laden and practice-laden, i.e. technique-laden, of our putting questions to nature that empirical reality must be investigated from particular perspectives: nature can be known scientifically only from a potentially infinite (not determinable a priori) number of perspectives or theoretical points of view, concretely exemplified by mechanisms or experimental ‘machines’ that allow specific access to specific aspects of sensible reality.     

What Are the Brain Mechanisms on Which Psychological Processes Are Based?

ABSTRACT— That the human brain is the organ of the mind is not in dispute, but we know remarkably little about the brain mechanisms underlying the mind. What are the functional structures and computational processes of the human brain that subserve cognition, emotion, and behavior? Given the complexity of the human brain, progress in understanding the functional organization and structure of the human brain depends on sophisticated theoretical specifications of the psychological representations and processes that differentiate two or more comparison conditions. Psychological scientists, therefore, are well positioned to lead the search for brain mechanisms underlying psychological processes. Doing so constitutes an expansion of the purview of psychological science beyond a science of behavior, and beyond a science of the mind, to include a science of the brain. Such an expansion of the mission of psychological science has implications for the infrastructure and training needs of the discipline.     

Mechanisms of priming of pop-out: Stored representations or feature-gain modulations?

Previous research has shown that repetition of a task-relevant attention-capturing feature facilitates popout search. This priming of pop-out effect is due to some residual memory from recent trials. We explore two possible mechanisms of priming of pop-out: a top-down attentional benefit from a memory of the previous target representation that is stored in visual short-term memory (VSTM) and a bottom-up change of attentional gains from perceptual features of the previously attended target. We manipulated participants’ ability to form a memory trace in VSTM by occupying it with a distractor task and found that occupying VSTM did not interfere with priming of pop-out. We next manipulated attentional gains associated with feature values by inserting an irrelevant task between pop-out searches. We found that the color of the target from the intervening perceptual task influenced pop-out search: The current pop-out search was facilitated when the intervening task’s target matched the target color of the pop-out search. These results suggest that priming of pop-out might not be due to a memory trace of the previous targets in VSTM but, rather, might be due to changes in attentional control based on priming from relatively low-level feature representations of previously attended objects.     

Direct Associations or Internal Transformations? Exploring the Mechanisms Underlying Sequential Learning Behavior

We evaluate two broad classes of cognitive mechanisms that might support the learning of sequential patterns. According to the first, learning is based on the gradual accumulation of direct associations between events based on simple conditioning principles. The other view describes learning as the process of inducing the transformational structure that defines the material. Each of these learning mechanisms predicts differences in the rate of acquisition for differently organized sequences. Across a set of empirical studies, we compare the predictions of each class of model with the behavior of human subjects. We find that learning mechanisms based on transformations of an internal state, such as recurrent network architectures (e.g., Elman, 1990), have difficulty accounting for the pattern of human results relative to a simpler (but more limited) learning mechanism based on learning direct associations. Our results suggest new constraints on the cognitive mechanisms supporting sequential learning behavior.     

Adaptation to altered visual—vestibular feedback: Mechanisms of maintenance and recovery

Adaptation of perceived movement during head motion (apparent concomitant motion, ACM) and the subsequent elimination of adaptation were studied in two experiments. During the adaptation phase of both experiments, subjects performed voluntary 1-Hz head oscillations for 6 min while fixating a stimulus moving either in the same (with) direction as or the opposite (against) direction of head movements. In Experiment 1, ACM adaptation was measured following either a 1- or a 4-min delay after the adaptation phase. Results indicated some loss of adaptation during the additional 3-min delay, demonstrating a tendency of the system linking head and image to return to its preadaptation state following removal of an adaptation stimulus. In Experiment 2, subjects viewed a stimulus after adaptation that appeared to move minimally in the same manner as the adaptation stimulus during 3 min of head oscillations. No loss of adaptation was measured in these subjects between the beginning and the end of the 3-min interval. In another condition, subjects viewed a stimulus that appeared to move alternately in the same direction as and in the opposite direction of the adaptation stimulus during a similar 3-min interval following adaptation. ACM adaptation was substantially reduced during this 3-min interval. These results implicate two mechanisms that operate to either maintain or eliminate ACM adaptation. One is passive and operates in the absence of visual feedback to eliminate the short-term adapted state, and the other responds to postadaptation visual feedback.     

Motivational Mechanisms of Self-Concordance Theory: Goal-Specific Efficacy and Person–Organization Fit

Purpose

The purpose of this study was to elaborate on two mechanisms of self-concordance theory (SCT; Sheldon and Elliot in Pers Soc Psychol 24(5):546, 1998)—goal-specific efficacy and perceived person–organization (PO) fit—as mediators of the relationships between autonomous and controlled goal motives and goal accomplishment and job satisfaction.

Design/Methodology/Approach

Data were from two independently collected samples of administrative employees (N1 = 37, N2 = 102) and their significant others across two points in time.

Findings

Results indicated that autonomous motives were positively related to goal-specific efficacy and perceived PO fit (Time 1), and showed indirect effects on goal accomplishment and other-rated job satisfaction (Time 2). Controlled motives were negatively related to the same intermediaries and outcomes.

Implications

Goal motives implicate goal-specific outcomes, and individuals’ overall composition of goal motives—across their goals—shape their goal efficacy and PO fit perceptions. These mechanisms relate to distal outcomes of goal accomplishment and job satisfaction. The research offers theoretical implications for the proximal outcomes of goal motives, but also practical implications for ways in which organizations can improve incumbent PO fit perceptions.

Originality/Value

Although research has shown that having self-concordant goals is positively associated with individual outcomes, existing research has yet to understand why this is the case. In addition, most studies of SCT apply difference scores to study the construct at the individual-level rather than specifying motives separately and considering a multilevel perspective. Our research offers a novel investigation of the proximal outcomes of SCT and the levels at which they operate.

     

Why does ADHD Confer Risk for Cigarette Smoking? A Review of Psychosocial Mechanisms

Research has documented that adolescents and young adults with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for cigarette smoking, but less attention has examined why this risk exists. The current paper reviews the literature on different psychosocial mechanisms [self-medication hypothesis, social factors (social modeling, social impairments), cognitive factors (attitudes, coping skills), and psychological variables (ADHD symptom dimensions, comorbidity)] that might explain this increased smoking risk. Results of the review suggest that, while the self-medication hypothesis has some theoretical merit, it has not been adequately examined among adolescents and young adults with ADHD. Further, cognitive and social factors may be important mechanisms that help to explain the association between ADHD and cigarette smoking, but research in these areas is sparse. Finally, a larger body of literature suggests that different psychological aspects of ADHD (e.g., comorbidity, symptom dimensions) are related to smoking. Interpretation of findings of many of these studies was hindered due to significant methodological problems and the lack of a guiding theoretical orientation. Potential theories that might facilitate future work in this area are discussed. Future research should continue to explore these important psychosocial mechanisms as well as gene–environment interactions in examining the link between ADHD and cigarette smoking.     

Intergenerational Continuity in Qualities of the Parent–Child Relationship: Mediating and Moderating Mechanisms

Intergenerational continuity in parenting quality has been demonstrated but the mechanisms underlying this continuity are less understood. This study investigated whether the offspring personality and years of education mediate the continuity in qualities of the parent–child relationship and whether offspring personality moderates this association. The sample comprised 1308 Finnish offspring (G2; 62% female) and their mothers (G1). G1 (Mean age?=?37.7) reported self-perceived qualities of the parent–child relationship in terms of emotional warmth and acceptance towards G2 aged 3–18 years in 1980. Thirty-two years later, once having become parents themselves, G2 (Mean age?=?42.9) self-rated their own qualities of the parent–child relationship towards their children using the same scales. Between these follow-ups, G2 self-rated their personality (consisting of temperament and character traits) using the Temperament and Character Inventory and reported years of education. Results indicated that G2 character traits—Self-directedness and Cooperativeness—partially mediated the intergenerational continuity in self-perceived emotional warmth and explained 16% of this association. No mediating role of G2 temperament traits was found (all ps?>?.240). Character traits accounted for the indirect association better than education in a multiple mediator model. Moreover, no moderating role of either temperament or character traits was found (all ps?≥?.064). Study findings show that warm and accepting qualities of the parent–child relationship in childhood are related to offspring character traits that reflect personality maturity in adulthood, which in turn would predict their own positive parent–child relationship later in life.
