Fatigue: relationships with basic personality and temperament dimensions

This study examined the relationships between the Five-Factor-Model (FFM) personality dimensions (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness/Autonomy), the Pavlovian temperament variables (Strength of Excitation, Strength of Inhibition, Mobility), and fatigue. We expected that all these person characteristics would be negatively associated with fatigue. In a survey among persons working at least 20 h a week (N=765), respondents completed a personality questionnaire (the Five-Factor Personality Inventory), a temperament scale (the Pavlov Temperament Survey), and two fatigue questionnaires (the Checklist Individual Strength-20 and the Emotional Exhaustion scale of the Maslach Burnout Inventory). Results indicated that high scores on Autonomy, and low scores on Extraversion, Conscientiousness, Emotional Stability, and Strength of Excitation were, in various combinations, predictors of higher fatigue scores. Agreeableness, Strength of Inhibition, and Mobility did not play a role in the prediction of any fatigue score. In conclusion, personality and temperament dimensions explained significant proportions of the variance in fatigue. It is stated that there is an urgent need for longitudinal studies in order to examine the predictive value of the personality dimensions over time.     

When differences matter: intergroup distinctiveness and the evaluation of impostors

The present study examined the effect of intergroup distinctiveness and group membership on evaluations of impostors. We predicted that ingroup members would be harsher than outgroup members on an impostor and that perceptions of intergroup distinctiveness would further moderate these evaluations. Specifically, we tested the social identity theory prediction that low intergroup distinctiveness would lead to greater derogation of the impostor (the ‘reactive distinctiveness’ hypothesis) against the self‐categorization hypothesis that high intergroup distinctiveness would instigate more derogation of an impostor (the ‘reflective distinctiveness’ hypothesis). In this study, vegetarians (ingroup members) and meat eaters (outgroup members) were presented with a target claiming to be vegetarian, but caught indulging in a meat dish. We found that ingroup members derogated the impostor more and felt less pleased about discovering the impostor behaviour than did outgroup members. In line with the reflective distinctiveness hypothesis, the heightened derogation displayed by ingroup members only emerged when intergroup distinctiveness was high, an effect that was mediated by ratings of group identification. The discussion focuses on the different responses intergroup distinctiveness may evoke. Copyright © 2005 John Wiley & Sons, Ltd.     

Distress in couples coping with cancer: a meta-analysis and critical review of role and gender effects

Research concerning distress in couples coping with cancer was integrated using meta-analysis and narrative critical appraisal. Individual levels of distress were determined more by gender than by the role of being the person with cancer versus that person's partner. That is, women reported consistently more distress than men regardless of their role (standardized mean difference = 0.31). The association between patient and partner distress within couples was only moderate (r = .29) but is sufficient to warrant further consideration of the notion that these couples react as an emotional system rather than as individuals. It is noteworthy that this association is not moderated by gender. With a general lack of comparison groups, the question of how much distress can be ascribed to the cancer experience cannot be answered decisively; elevations in distress are probably modest. We critically discuss these results, identify important unanswered questions, and indicate directions for future research. Attention needs to be directed toward factors other than cancer as direct influences of distress in these couples and to mediators and moderators of the cancer experience.     

'I remember therefore I am, and I am therefore I remember': exploring the contributions of episodic and semantic self-knowledge to strength of identity

The present research explores the relationship between the two components of autobiographical memory--episodic and semantic self-knowledge--and identity strength in older adults living in the community and residential care. Participants (N= 32) completed the autobiographical memory interview and measures of personal identity strength and multiple group memberships. Contrary to previous research, autobiographical memory for all time periods (childhood, early adulthood, and recent life) in the semantic domain was associated with greater strength in personal identity. Further, we obtained support for the hypothesis that the relationship between episodic self-knowledge and identity strength would be mediated by knowledge of personal semantic facts. However, there was also support for a reverse mediation model indicating that a strong sense of identity is associated with semantic self-knowledge and through this may enhance self-relevant recollection. The discussion elaborates on these findings and we propose a self-knowledge and identity model (SKIM) whereby semantic self-knowledge mediates a bidirectional relationship between episodic self-knowledge and identity.     

When group members admit to being conformist: the role of relative intragroup status in conformity self-reports

Five studies examined the hypothesis that people will strategically portray the self as being more group influenced the more junior they feel within the group. Among social psychologists (Study 1), ratings of self-conformity by group members were greater when the status of the participant was low than when it was high. These effects were replicated in Studies 2, 3, and 4 in which relative intragroup status was manipulated. In Study 3, the authors found junior group members described themselves as more conformist than senior members when they were addressing an ingroup audience, but when they were addressing an outgroup audience the effect disappeared. Furthermore, junior members (but not senior members) rated themselves as more conformist when they were led to believe their responses were public than when responses were private (Study 5). The discussion focuses on the strategic processes underlying low-status group members' self-reports of group influence and the functional role of conformity in groups.     

Protecting threatened identity: sticking with the group by emphasizing ingroup heterogeneity

In two studies (Ns=163, 164), the authors tested the prediction that perceptions of group variability can steer and guide the way that loyalty is expressed in times of identity threat. In both studies, participants were classified as lower or higher identifiers on the basis of their scores on a group identification measure, and manipulations involved group variability perceptions (homogeneous ingroup vs. heterogeneous ingroup) and threat to the ingroup. Higher identifiers presented with a homogeneous ingroup perceived more ingroup homogeneity under threat than when there was no threat. In contrast, higher identifiers who perceived the ingroup initially as heterogeneous perceived more ingroup heterogeneity under threat than in no threat conditions. Lower identifiers perceived more ingroup heterogeneity under threat (vs. no threat) irrespective of manipulated group variability perceptions. Discussion focuses on different ways that group loyalty can be expressed in times of identity threat.     

Personality judgments in adolescents' families: the perceiver,the target,their relationship,and the family

The present study investigated whether personality judgments involve different processes in a family setting than in a nonfamily setting. We used the Social Relations Model to distinguish the effects of perceiver, target, perceiver-target relationship, and family on personality judgments. Family members of families with adolescents judged their own and the other members' Big Five factors. Judgments were found to depend on the relevance of personality factors within the family setting: Agreeableness and Conscientiousness were judged most consistently. Large relationship variance indicated that parents adjust their judgments to the target family member; large perceiver variance indicated that adolescents judge family members' personalities rather similarly. However, a comparison of self- and other-judgments showed adolescents' judgments to be no more related to their self-perceptions than parents' judgments. We concluded that the relevance of personality factors may differ on specific tasks within a setting.     

How living in economically unequal societies shapes our minds and our social lives

In recent decades, the economies of many countries have produced increasingly unequal outcomes for the rich and poor. This economic trend has attracted interest from members of the media, public and political classes as well as researchers who are interested in its societal implications. While this research has traditionally been the purview of economists and sociologists, there has been a burgeoning growth in research that has sought to understand the psychology of economic inequality. In this review, we summarize this work, focusing on two major themes: (1) how people perceive the scale of economic inequality and appraise its significance, and (2) how living in an economically unequal environment shapes people's social lives. Together, this work affirms claims that economic inequality is ‘the defining issue of our time’ (Obama, 2013) with a great deal of destructive potential. We identify important questions that await further research attention.     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.
