We tested whether and why observers dislike individuals who convey self-superiority through blatant social comparison (the hubris hypothesis). Participants read self-superiority claims (\"I am better than others\"; Experiments 1-7), noncomparative positive claims (\"I am good\"; Experiments 1-2, 4), self-equality claims (\"I am as good as others\"; Experiments 3-4, 6), temporally comparative self-superiority claims (\"I am better than I used to be\"; Experiment 5), other-superiority claims (\"S/he is better than others\"; Experiment 6), and self-superiority claims accompanied by persistent disclaimers (Experiment 7). They judged the claim and the claimant (Experiments 1-7) and made inferences about the claimant's self-view and view of others (Experiments 4-7) as well as the claimant's probable view of them (Experiment 7). Self-superiority claims elicited unfavorable evaluations relative to all other claims. Evaluation unfavorability was accounted for by the perception that the claimant implied a negative view of others (Experiments 4-6) and particularly of the observer (Experiment 7). Supporting the hubris hypothesis, participants disliked individuals who communicated self-superiority beliefs in an explicitly comparative manner. Self-superiority beliefs may provoke undesirable interpersonal consequences when they are explicitly communicated to others but not when they are disguised as noncomparative positive self-claims or self-improvement claims.  相似文献

This study examined psychologists' views and practices regarding diagnostic classification systems for mental and behavioral disorders so as to inform the development of the ICD‐11 by the World Health Organization (WHO). WHO and the International Union of Psychological Science (IUPsyS) conducted a multilingual survey of 2155 psychologists from 23 countries, recruited through their national psychological associations. Sixty percent of global psychologists routinely used a formal classification system, with ICD‐10 used most frequently by 51% and DSM‐IV by 44%. Psychologists viewed informing treatment decisions and facilitating communication as the most important purposes of classification, and preferred flexible diagnostic guidelines to strict criteria. Clinicians favorably evaluated most diagnostic categories, but identified a number of problematic diagnoses. Substantial percentages reported problems with crosscultural applicability and cultural bias, especially among psychologists outside the USA and Europe. Findings underscore the priority of clinical utility and professional and cultural differences in international psychology. Implications for ICD‐11 development and dissemination are discussed.  相似文献

A large body of research has clearly demonstrated that healthy ageing is accompanied by an associative memory deficit. Older adults exhibit disproportionately poor performance on memory tasks requiring the retention of associations between items (e.g., pairs of unrelated words). In contrast to this robust deficit, older adults’ ability to form and temporarily hold bound representations of an object's surface features, such as colour and shape, appears to be relatively well preserved. However, the findings of one set of experiments suggest that older adults may struggle to form temporary bound representations in visual working memory when given more time to study objects. However, these findings were based on between-participant comparisons across experimental paradigms. The present study directly assesses the role of presentation time in the ability of younger and older adults to bind shape and colour in visual working memory using a within-participant design. We report new evidence that giving older adults longer to study memory objects does not differentially affect their immediate memory for feature combinations relative to individual features. This is in line with a growing body of research suggesting that there is no age-related impairment in immediate memory for colour-shape binding.  相似文献

African Americans are disproportionately affected by the HIV epidemic inclusive of men who have sex with men, heterosexual men, and women. As part of a community‐based participatory research study we assessed HIV testing experience among sexually active 18–30 year old Black men and women in Durham, NC. Of 508 participants, 173 (74 %) men and 236 (86 %; p = 0.0008) women reported ever being tested. Barriers to testing (e.g., perceived risk and stigma) were the same for men and women, but men fell behind mainly because a primary facilitator of testing—routine screening in clinical settings—was more effective at reaching women. Structural and behavioral risk factors associated with HIV infection were prevalent but did not predict HIV testing experience. Reduced access to health care services for low income Black young adults may exacerbate HIV testing barriers that already exist for men and undermine previous success rates in reaching women.  相似文献

Two studies investigate the psychological processes underlying short- and long-term effects of video game violence on interpersonal trust. Study 1 demonstrates that interacting with physically aggressive virtual agents decreases players' trust in subsequent interactions. This effect was stronger for players who were dispositionally sensitive to victimization. In Study 2, long-term effects of adolescents' frequent exposure to video game violence on interpersonal trust and victim sensitivity were investigated. Cross-lagged path analyses show that the reported frequency of playing violent video games reduced interpersonal trust over a period of 12 months, particularly among victim-sensitive players. These findings are in line with the sensitivity to mean intentions (SeMI) model, and they suggest that interpersonal mistrust is a relevant long-term outcome of frequent exposure to video game violence.  相似文献

Three levels of working memory load of a visual search (Memory and Search) task were tested in a 72-hour sleep deprivation paradigm. General performance and accuracy decrease over time with monotonic and rhythmic components. The signal detection discriminability index, d', decreases monotonically with rhythmic variations. The index of response bias, β, shows no monotonic trend, but significant circadian rhythmicity. The extent of the monotonic and rhythmic changes in accuracy and in d' is directly related to the level of working memory load. The amplitude of the circadian component of accuracy and d' is enhanced for the higher levels of working memory load. The implication of potentiated circadian rhythmicity as a function of cumulative sleep loss is discussed.  相似文献

In the present research the interaction between the endogenous ligand for the cannabinoid CB1 receptor anandamide (arachidonylethanolamide) and morphine in memory consolidation was investigated. Four sets of experiments were carried out with CD1 mice tested in a one-trial inhibitory avoidance task. The drugs were administered intraperitoneally after training of the animals in the apparatus. In the first set of experiments morphine (0.3 or 0.5, but not 0.15mg/kg) or anandamide (3 or 6 but not 1.5mg/kg) dose-dependently impaired memory consolidation. In the second set of experiments the administration of an otherwise ineffective dose of anandamide (1.5mg/kg) enhanced the memory impairment exerted by morphine (0.3 and 0.5mg/kg) when the drugs were injected immediately after training. In the third set of experiments the combined treatments of anandamide (1.5mg/kg) and morphine (0.5mg/kg) 2h after training were ineffective showing that the effects observed on performance following immediate posttraining administration of anandamide and morphine combinations were reflecting direct influences on memory consolidation. In the fourth set of experiments otherwise ineffective doses of the D1 DA receptor agonist SKF 38393 or the D2 DA receptor agonist LY 171555 antagonized the memory impairment produced by anandamide and morphine in combination, suggesting a possible involvement of dopaminergic mechanisms.  相似文献

An operationalization of mental pain is presented in three studies. The first study describes the operationalization of mental pain and the factor structure of the items produced by a content analysis of self-reports yielding a scale with nine factors: the experience of irreversibility, loss of control, narcissistic wounds, emotional flooding, freezing, estrangement, confusion, social distancing, and emptiness. Study 2 tested the relationship between mental pain and depression and anxiety in a normal population. Study 3 focused on the relationship between mental pain and coping. Mental pain is conceptualized as a perception of negative changes in the self and its functions that are accompanied by negative feelings. It is suggested that it can be meaningfully applied to the study of different mental states, life conditions, and transitions in life.  相似文献

Past research has shown that attachment orientations shape sexual processes within relationships. Yet, little has been done to explore the opposite direction. In the present research, we examined whether sexual desire and emotional intimacy reduce attachment insecurities over time in emerging relationships. In an 8‐month longitudinal study, we followed 62 newly dating couples across three measurement waves. At Time 1, romantic partners discussed sexual aspects of their relationship and judges coded their displays of sexual desire and intimacy. Participants also completed measures of relationship‐specific attachment anxiety and avoidance in each wave. The results indicated that men's displays of desire predicted a decline in their own and their partner's relationship‐specific insecurities. Conversely, women's displays of desire inhibited the decline in their partner's relationship‐specific insecurities, whereas women's displays of intimacy predicted a decline in their partner's relationship‐specific insecurities. These findings suggest that different sex‐related processes underlie attachment formation in men and women.  相似文献
