Black individuals have been found to report the highest levels of self-esteem of any racial group in the United States. The purpose of the present research was to examine whether Black individuals also report higher levels of narcissism than White individuals. Study 1 (N = 367) found that Black individuals reported higher levels of narcissism than White individuals even when controlling for gender, self-esteem level, and socially desirable response tendencies. Study 2 (N = 967) and Study 3 (N = 315) found similar results such that Black individuals reported higher levels of narcissism than White individuals on the narcissism measures that captured less pathological facets of this construct. Study 3 also included indicators of psychological adjustment and found that the pathological aspects of narcissism were more strongly associated with maladjustment for Black individuals than for White individuals. The implications of these results for understanding the Black self-esteem advantage are discussed.  相似文献

The present study had two aims: First, to investigate the joint and specific roles of working memory (WM) and intelligence as predictors of school achievement. And second, to replicate and extend earlier findings (Spinath, Spinath, Harlaar, & Plomin, 2006) on the incremental validity of non-cognitive over cognitive abilities in the prediction of school achievement. The present sample consisted of N = 179 Chinese primary school children in the fourth grade. All measures including working memory (WM), intelligence and motivational items were assessed in class. Teachers provided test scores for the domains of Chinese and Math. We found that WM was a good predictor of school achievement and comparable in predictive power to intelligence. Together, cognitive ability including both WM and intelligence explained 17.8% and 36.4% of the variance in children's Chinese and Math scores, respectively. The relative importance of WM and intelligence varied with school domains with greater predictive power of WM for Math while intelligence explained a greater proportion of the variance in Chinese although the magnitude of this difference was only moderate. Domain-specific motivational constructs contributed only marginally to the prediction of school achievement for both Chinese and Math.  相似文献

Safety in numbers is thought to be the principal advantage of living in groups for many species. The group can only provide protection against predators, however, when group cohesion is maintained. Vocalisations are used to monitor inter-individual distances, especially under conditions of poor visibility, but should be avoided in the presence of predators. Mentally tracking the movements of silent and invisible group members would allow animals foraging in dense vegetation to stay close to their group members while reducing the use of vocal contact. We tested the socio-spatial cognitive abilities of wild vervet monkeys (Chlorocebus pygerythrus) by comparing their reactions to plausible and implausible displacements of group members simulated by sound playbacks. Our methods are comparable to those used in studies of ‘object permanence’ and ‘invisible displacements’ of inanimate objects. Our results show that vervets can track the whereabouts of invisibly and silently moving group members, at least over short periods of time.  相似文献

IntroductionSo far, no qualitative content analysis (QCA) has analysed pilots’ experiences and perceptions regarding weaknesses of fatigue risk management (FRM), flight time limitations (FTL), rosters, fatigue-severity, sleep problems, and how they relate to pilots’ mental health and well-being.ObjectiveThis research analyses pilots’ described perceptions of stress, fatigue, aviation safety and how regulations like FTL can affect their health and well-being.MethodIn total, 119 international pilots described their perceptions of FTL, rosters, aviation safety, and how they relate to fatigue and health. The QCA was conducted to analyse interactions of working conditions, stressors, fatigue, sleep problems and mental health of EASA-based and Australian pilots.ResultsAlthough pilots were rostered for only 60.8% to 62.5% of the legally allowed duty and flight hours/month, 78.6% reported severe or very high fatigue, 22.8% significant depression, 12.3% significant anxiety symptoms, 10.5% reported significant depression and anxiety symptoms. Pilots uttered severe concerns about FTL, sleep restrictions associated with early starts, minimum rest, etc. Pilots also expressed distinct fears regarding more fatigue-related crashes, and how adverse working conditions, work-related and psychosocial stress could impair their health.ConclusionsThis QCA provided valuable insights into interactions of working conditions, fatigue, sleep restrictions, physical and mental health. Progressive health impairment due to lack of sleep and accumulated fatigue promote burnout, mental and physical health problems, which not only threaten flight safety, but also sustainability of aviation.  相似文献

This paper examines some of the debates over maternal instinct in France under the Third Republic. It focuses on the work of three naturalists (Fabre, Perrier, and Giard) and shows how these scientists shaped, reinforced, or challenged feminine identities as well as a number of sexual social conventions making constant reference to the natural as their authority. This paper highlights these scientists’ views on womanhood and maternity and their stances on contemporary feminist discourses as well as seeking to establish the extent to which these views and stances influenced their scientific discourses and practices. It also aims to demonstrate the interpenetration of science and policy, not only in terms of the transfer of political concepts into the scientific domain (and back again), but also as a joint construction process, which produced a new political and natural order in nineteenth century France.  相似文献

This study represents the first longitudinal examination of the trajectory of overgeneral memory (OGM) in children and how this relates to psychopathology immediately after trauma exposure. We recruited fifty 7‐ to 17‐year‐olds who had experienced an accidental injury that resulted in hospital admission. Assessment of psychological symptoms, OGM and cognitive processes proposed to drive OGM was completed at three points over a 6‐month period post‐trauma. We found that OGM was not related to depressive symptoms and that time since trauma exposure moderated the relationship between post‐traumatic stress disorder symptoms and OGM. Although no relationship was found in the first 3 months following trauma, OGM was protective against post‐traumatic stress disorder symptoms at 6 months post‐trauma. Despite models of OGM (e.g. Williams et al., 2007 ) emphasising the role of rumination and executive control in explaining OGM, we found no evidence that they were related to OGM.
