Emotional, cognitive and physiological correlates of abuse-related stress in borderline and antisocial personality disorder

Childhood abuse is an important precursor of borderline personality disorder (BPD) and antisocial personality disorder (ASPD). The current study compared the emotional reactivity to abuse-related stress of these patients on a direct and an indirect level. Changes in self-reported affect and schema modes, psychophysiology and reaction time based cognitive associations were assessed following confrontation with an abuse-related film fragment in patients with BPD (n = 45), ASPD (n = 21), Cluster C personality disorder (n = 46) and non-patient controls (n = 36). Results indicated a hyperresponsivity of BPD-patients on self-reported negative affect and schema modes, on some psychophysiological indices and on implicit cognitive associations. The ASPD-group was comparable to the BPD group on implicit cognitions but did not show self-reported and physiological hyper-reactivity. These findings suggest that BPD and ASPD-patients are alike in their implicit cognitive abuse-related stress reactivity, but can be differentiated in their self-reported and physiological response patterns.     

Weighing the Evidence: Social Desirability, Eating Disorder Symptomatology, and Accuracy of Self-reported Body Weight Among Men and Women

Although self-reported measurement of body weight is commonly accepted practice, this method may yield inaccurate estimates varying by respondent gender, body mass index, and eating disorder symptomatology. Given the gendered nature of idealized body weight in the U.S., we examined whether or not these variables and positive impression management are associated with inaccurate weight reporting among undergraduates. College women (n?=?107) and men (n?=?48) from a small liberal arts school in the Northeastern U.S. self-reported height and weight, completed the Eating Disorder Examination Questionnaire, Personality Assessment Inventory-Positive Impression Management scale, and three scales from the Eating Disorder Inventory-3, and were then weighed. Paired t-tests compared self-reported and measured body weight for men and women separately, and respondents were then categorized as under- or over-reporters by gender. Independent samples t-tests were conducted separately for men and women comparing weight under- and over-reporters on BMI, levels of eating disorder symptomatology, and social desirability. Results indicate discrepancies between self-reported and measured body weight were significant. Among those who over-reported weight, men exhibited greater over-reporting than did women. Weight under-reporting was associated with higher BMI, and for women, lower eating disorder symptomatology and higher social desirability scores. There may be inaccuracies in self-reported weight based on positive impression management, BMI, and eating disorder symptomatology, but these appear to differ by gender. Future research should explore the roles of personality, social desirability, and competing pressures for muscularity versus thinness in weight reporting accuracy among men and women.     

The associations of the Five Factor Model of personality with inflammatory biomarkers: A four-year prospective study

This study evaluated the associations of the Five Factor Model of personality with two inflammation biomarkers, C-reactive protein and fibrinogen, and the possible moderating effects of common health-related behaviors (physical activity and smoking) concurrently and over four years, while adjusting for socio-demographic and health status. Participants were individuals who underwent a health examination at two points of time, T1 (n = 1709) and T2 (n = 923), about four years apart. Regression analyses uncovered positive associations between Neuroticism and Extraversion with two inflammatory biomarkers at baseline (T1) and over time (T2) and increases in their levels over time. Additionally, a synergistic interaction of neuroticism and physical inactivity was associated with higher levels of inflammation biomarkers at both time periods. Openness was negatively associated with inflammation biomarkers at T1 and T2, but not with changes in their levels. No significant associations were found for Agreeableness and Conscientiousness. The results suggest that personality traits might be involved in the inflammatory process both concurrently and over time, and thus indicate a possible mechanism by which personality traits might influence health, especially cardiovascular disease risk.     

Self-Report and Observer Ratings of Personality Functioning: A Study of the OPD System

Recent considerations around DSM–5 criteria of personality disorders (PDs) demand new concepts of assessing levels of personality functioning. Of special interest are multiperspective approaches accounting for clinicians’ as well as patients’ points of view. The study investigates observer-rated and self-assessed levels of personality functioning measured by the level of structural integration as defined by the Operationalized Psychodynamic Diagnosis System (OPD). Both perspectives were positively related. The combination of both measures was most efficient in discriminating among 3 diagnostic groups of varying degrees of personality dysfunction. Future studies should take into account expert ratings as well as self-report data.     

The role of executive function,personality and attitudes to risks in explaining self-reported driving behaviour in adolescent and adult male drivers

Young drivers show high levels of risky driving and are over-represented in motor vehicle crash statistics world-wide. As well as personality and attitudinal factors, high rates of risk taking during adolescence may be due to poorly developed executive functions, a result of the slow maturation of the pre-frontal cortex of the brain. This study was undertaken to investigate the roles of executive function, personality, attitudes to risk in relation to self-reported driving behaviour. Adolescent (n = 46, age 16–18 years) and adult (n = 32, 25 years and over) male drivers completed a battery of neuropsychological tests to assess general cognitive ability and executive function, and questionnaires to assess driving history, personality, attitudes to physical and psychological risk as well as questionnaires of self-reported driving behaviour (Driver risk taking and Driver Attitude Questionnaire, DAQ). The adolescent drivers showed poorer executive function, higher levels of impulsivity and risk-taking, lower levels of agreeableness and conscientiousness compared to adult drivers. Regression analyses revealed that attitudes to risk, agreeableness and working memory made unique significant contributions in explaining self-reported driving behaviour. Interestingly though, better working memory was associated with higher levels of self-reported risky driving and more accepting attitudes to risky driving. Together the findings suggest that some aspects of executive function, personality, and attitudes to risk may help to explain self-reported driving behaviour. Whether these findings are relevant to female drivers and apply to on-road driving behaviour should be the focus of future studies.     

Testosterone reactivity to infant crying and caregiving in women: The role of oral contraceptives and basal cortisol

Several studies have shown that mothers and fathers have significant lower levels of testosterone (T) than non-mothers and non-fathers, and that in men caregiving is related to a decrease in T. To date, only a few studies have examined T in women. We examined T reactivity to a crying infant simulator in 160 women. Use of oral contraceptives (OC), basal cortisol (CORT) levels and childhood experiences of maternal love withdrawal were taken into account. T levels were consistently significantly higher in women not using OC. In women not using OC, high basal CORT was related to higher initial T levels and larger decreases of T during caregiving. No effect of basal CORT was found in women with OC use. Childhood experiences of maternal love withdrawal did not affect T levels. This is the first study to show support for a decrease of T in women while taking care of a crying infant, supporting the Challenge hypothesis and the Steroid/Peptide Theory of Social Bonds.     

Measurement of Preoperative Anxiety in Young Children: Self-report Versus Observer-rated

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used, observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS), and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy.     

Digit ratio (2D:4D) and aggregate personality scores across nations: Data from the BBC internet study

The purpose of this study was to consider relationships between digit ratio (2D:4D, a putative correlate of prenatal sex steroids) and aggregate personality scores across nations. Differences in national personality scores may be influenced by such factors as prevalence of the parasite Toxoplasma gondii, latitude and economics, and variation in 2D:4D has also been linked to prevalence of T. gondii and to latitude. Here we report associations of mean 2D:4D per country and latitude, gross domestic product (GDP), T. gondii prevalence and personality profiles in 23 nations of an internet study. 2D:4D was not related to latitude or to T. gondii, but was related to GDP (women only). With regard to national personality scores, 2D:4D was not related to masculinity but there were significant positive relationships of 2D:4D with uncertainty avoidance in men and women and with neuroticism in men. Male 2D:4D was significantly related to uncertainty avoidance and neuroticism independent of T. gondii, whereas female 2D:4D was not significantly related to uncertainty avoidance or neuroticism after controlling for the effect of T. gondii and GDP. We conclude that nations with high male 2D:4D (low prenatal testosterone, high prenatal oestrogen) have high scores for uncertainty avoidance and neuroticism.     

Effects of implicit power motivation on men's and women's implicit learning and testosterone changes after social victory or defeat

Two studies examined interactions of implicit power motivation and experimentally varied victory or defeat in a contest on implicit learning of a visuomotor sequence associated with the contest outcome and changes in testosterone and self-reported affect. In men and women, power motivation predicted enhanced learning (sequence-execution accuracy) after a victory and impaired learning after a defeat. In men, power motivation predicted testosterone increases among winners and decreases among losers, and testosterone decreases mediated the negative effect of power motivation on learning in losers. In women, power motivation predicted postcontest testosterone increases, particularly among losers. In both men and women, self-reported affective states were influenced only by contest outcome and were unrelated to participants' testosterone changes or implicit learning.     

Personality and conflict communication patterns in cohabiting couples

We assessed the links between the five major personality dimensions and perceptions of conflict communication patterns within cohabiting heterosexual couples. Participants were 79 couples (N = 158) who completed the International Personality Item Pool (Goldberg, 1999) and the Communication Patterns Questionnaire (Christensen & Sullaway, 1984). Intraclass correlations were computed to determine whether communication patterns should be analyzed at the dyad or individual level. Results showed that self-reported neuroticism and conscientiousness among men were the strongest predictors of dyadic perceptions of constructiveness, avoidance and withholding, and man demand–woman withdraw. However, no significant personality predictors of men’s and women’s perceptions of woman demand–man withdraw were found. Possible explanations for these results are canvassed and the discussion is framed in the context of previous research findings as well as the nature of the major personality dimensions.     

Test anxiety and ego-threatening stress: Over- (and under-) estimation of emotional reactivity

Abstract

This study examined discrepancies between subjective and objective measures of state anxiety as a function of test anxiety in undergraduates. Under evaluative stress conditions, state anxiety was assessed in terms of (a) self-reported cognitive and somatic anxiety, (b) behavioral reactivity (motor and facial tension, avoidance comments and avoidance of eye contact), (c) physiological arousal (heart rate and skin resistance), and (d) cognitive and motor task performance. Participants high in test anxiety showed disproportionately greater self-reported than objective state anxiety. In contrast, those low in test anxiety showed lower self-reported than objective anxiety. The high- and the low-test-anxiety groups differed only in self-reported emotional reactivity. In line with current cognitive theories of anxiety, overestimation of reactivity in high-test anxiety, as well as underestimation in low-test anxiety, are conceptualized as a hypervigilance bias and an avoidance bias, respectively, in processing internal cues, i.e., prioritization and inhibition of attention to one's own behavioral and physiological signs of distress.     

BMI,age, Mate Value,and Intrasexual Competition in Chilean Women

Attractiveness is the most important component of women intrasexual competition and it certainly has an impact in female’s perceived mate value (i.e., the value of an individual to the opposite sex as a potential mate). In the realm of intrasexual competition women are eager to emphasize their attractiveness and compete with rivals displaying these cues. Accordingly, age is an important feature of women’s appeal to the opposite sex; youth is highly valued by men, and is perceived by women as an important component of their attractiveness. Another trait that is a reliable cue of health and fertility is Body Mass Index (BMI). A large body of literature has associated BMI to female attractiveness. However, more information is necessary about the associations of BMI and age with mate value, and female intrasexual competition. In the present research we report two studies that examined the associations of BMI and age with estimates of self-perceived mate value and intrasexual competition in Chilean women (18–39 years). More specifically, we hypothesized inverse relationships of BMI and age with mate value (N?=?234), and intrasexual competition (N?=?308). We found partial support to our propositions. The results revealed inverse associations between BMI, mate value and mating success, but BMI with intrasexual competition were not related. In contrast, age had a strong and negative effect on intrasexual competition. We discuss our results within the framework of Evolutionary Psychology and consider the central role of attractiveness (estimated from BMI and age) in the mating strategies of women.     

Individual differences in hedonic capacity,depressed mood,and affective states predict emotional reactivity

Identifying factors that contribute to inter-individual differences in emotional reactivity is central to understanding the basic mechanisms that give rise to adaptive emotion reactivity and to disruptions that may occur in psychopathology. The current study related emotional reactivity in an unselected young adult sample (N?=?101) to individual difference factors relevant to emotional functioning and mood pathology, specifically anhedonia, depressed mood, and current affective state. To assess emotional reactivity, participants rated their emotional responses to 100 pictures from the International Affective Picture System. Increased self-reported anhedonia (i.e. reduced hedonic capacity) predicted blunted emotional reactivity to both positive and negative images, relative to neutral images, while elevated depressed mood predicted potentiated emotional reactivity to negative vs. neutral images. Anhedonia also accounted for far greater variance in emotional reactivity than depressed mood. Further, more positive affective state predicted potentiated reactivity to positive versus neutral images while more negative affective state predicted potentiated reactivity to negative versus neutral images beyond effects of anhedonia and depressed mood. The current study identified separable effects of anhedonia, depressed mood, and current affect on emotional reactivity.     

Personality from a controlled processing perspective: An fMRI study of neuroticism,extraversion, and self-consciousness

Although neuroticism has been central to most theories of personality, self-reported neuroticism has had limited success in predicting expected behavioral outcomes. The reason for this may be due, in part, to the imprecision of self-reports. The purpose of this study was to examine the relationship between neural correlates of control systems and neuroticism, extraversion, and self-consciousness. In response to an oddball task, neuroticism was associated with increased dorsal anterior cingulate cortex (dACC) reactivity, typically associated with discrepancy detection, whereas extraversion and self-consciousness were associated with lateral and medial frontoparietal networks, respectively, typically associated with task-focused (lateral) or self-focused (medial) controlled processes. We also examined whether the neural measure of neuroticism would predict a relevant behavioral outcome better than self-reports would. Interoceptive accuracy, an outcome associated with neuroticism, was better accounted for by dACC reactivity (r ²=.74) than by self-reported neuroticism (r ²=.16), suggesting that neural reactivities may provide a more direct measure of personality than self-reports do.     

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.     

Personality and situational correlates of self-reported reasons for intimate partner violence among women versus men referred for batterers' intervention

This study examines personality and situational correlates of self-reported reasons for intimate partner violence (IPV) among women and men court-ordered to batterers' intervention as IPV offenders. Women endorsed self-defense and men retaliation as their primary reasons for IPV. Both also endorsed emotion dysregulation as a reason for much of their violence. Women's partner violence was largely, but not exclusively, situationally motivated. Women's reasons for violence also related significantly to self-reported borderline personality symptomology. Men's reasons for IPV related primarily to their self-reported antisocial and borderline personality traits, not to situational factors. Thus, the IPV of some women and some men may be considered "characterological," in that it reflects something about the individual's character or personality. Control or domination of one's partner was not a primary reason for violence among women or men, despite the assumption on which many batterer intervention programs are based, that IPV is primarily a power and control tactic. Clinical implications and recommendations for future research are provided.     

From Adolescence to Later Adulthood: Femininity, Masculinity, and Androgyny in Six Age Groups

We drew from developmental theory regarding the timing of historical events in individuals’ lives to examine age-related differences in self-reported masculine, feminine, and androgynous personality traits in a cross-sectional sample of American men (N?=?357) and women (N?=?404) representing six age groups (adolescents [12–17 years], younger [18–29 years], middle-aged [40–59], young-old [60–69], old-old [70–79], and oldest-old [80 and older] adults). Oldest-old women were less likely than younger and middle-aged women to endorse masculine and androgynous traits. Men in their 70s (old-old) were more likely than adolescents and younger men to endorse androgynous traits. Discussion of the results emphasizes the implications of the second wave of the women’s movement for understanding life-span gender development.     

Narcissism Predicts Heightened Cortisol Reactivity to a Psychosocial Stressor in Men

Narcissists' sensitivity to social evaluation should increase their physiological reactivity to evaluative stressors. However, very few studies have assessed the physiological correlates of narcissism. In this study, participants completed an evaluative laboratory stressor or a non-evaluative control task. Cortisol reactivity-a marker of the hypothalamic-pituitary-adrenal (HPA) axis stress response-and negative affect (NA) were higher in the stress versus control condition. However, men showed larger cortisol responses and, among men, higher narcissism scores predicted greater cortisol reactivity and larger increases in NA. Narcissism was unrelated to cortisol reactivity and NA among women and in the control condition. These findings highlight the influence of defensive personality traits on HPA reactivity and suggest a pathway through which narcissistic traits might influence long-term health outcomes.     

Cognitive and Personality Characteristics of Masculinity and Femininity Predict Wayfinding Competence and Strategies of Men and Women

Bem (1974) reconceptualized masculinity and femininity as independent and orthogonal constructs that both men and women possess to varying degrees. This perspective was used as a starting point to investigate whether the contributions of gender-typed characteristics can help to account for commonly observed gender differences in wayfinding (the ability to identify one’s current location and successfully navigate to an unseen location in the environment) favoring men. We further divided gender-typed characteristics into cognitive and personality characteristics to assess their separate influence on wayfinding and explored whether gender-typed characteristics predicted self-reported use of masculine wayfinding strategies (i.e., orientation strategies) and self-reported wayfinding competence. Participants were 452 college women and men in a southern U.S. public university. They completed the Gender-Stereotypic Characteristics questionnaire (Diekman and Eagly 2000), a social comparison questionnaire (created by the authors), a wayfinding strategy questionnaire (Lawton 1994), and a wayfinding competence questionnaire (Hegarty et al. 2002). For both men and women, higher masculine cognitive characteristics significantly correlated with greater use of orientation wayfinding strategies typical of men. For men, both higher masculine and feminine cognitive characteristics predicted better overall wayfinding competence whereas for women, only higher masculine cognitive characteristics predicted better overall wayfinding competence. For both men and women, higher feminine personality characteristics predicted poorer wayfinding competence. These results demonstrated the importance of considering cognitive and personality characteristics of masculinity and femininity in explaining individual differences in wayfinding.     

Personality features and characteristics of violent events committed by juvenile offenders

The present study investigated the relationship between characteristics of a violent event, as self-reported by 82 incarcerated juvenile offenders, and personality features measured by the Millon Adolescent Clinical Inventory (MACI). The study predicted that specific personality features that have previously been associated with psychopathy would be associated with the instrumentality, emotional reactivity, and empathy or guilt reported for the incident. Results confirmed that a self-reported pattern of elevated instrumental motivation and reduced empathy or guilt was associated with higher scores on the MACI Forceful, Unruly, Substance Abuse Proneness, Impulsive Propensity, and Family Discord Scales, as well as a recently developed Psychopathy Content Scale. Self-reported elevated instrumental motivation and reduced empathy or guilt was also associated with lower scores on the Submissive, Conforming, Anxious Feelings, and Sexual Discomfort Scales. There were no significant relationships observed between emotional reactivity and personality scales.
