Past research indicates that being religious is associated with prejudice toward racial and value-violating out-groups. However, this past research treated religiosity as a unidimensional construct without taking into account how different components of religiosity—belief in a higher power and the rigidity/flexibility of religious beliefs—are associated with measures of prejudice. Two studies examined the relationship between these two components of religiosity, as measured by the Post-Critical Beliefs Scale, and racial (African Americans, Arabs) and value-violating prejudices (atheists, gay men). As the flexibility of religious beliefs increased (literal vs. symbolic dimension), attitudes toward racial and value-violating out-groups became more positive (Study 1). As belief in God strengthened (exclusion vs. inclusion of transcendence dimension), attitudes toward value-violating out-groups became more negative. Study 2 demonstrated that these two components of religiosity fully mediated the relationship between general religiosity and prejudice toward African Americans, Arabs, and gay men and partially mediated the relationship between religiosity and prejudice toward atheists. Results are discussed in light of reexamining the conclusion that simply being religious is associated with prejudice. 相似文献

ABSTRACTNegative emotion influences cognitive control, and more specifically conflict adaptation. However, discrepant results have often been reported in the literature. In this study, we broke down negative emotion into integral and incidental components using a modern motivation-based framework, and assessed whether the former could change conflict adaptation. In the first experiment, we manipulated the duration of the inter-trial-interval (ITI) to assess the actual time-scale of this effect. Integral negative emotion was induced by using loss-related feedback contingent on task performance, and measured at the subjective and physiological levels. Results showed that conflict-driven adaptive control was enhanced when integral negative emotion was elicited, compared to a control condition without changes in defensive motivation. Importantly, this effect was only found when a short, as opposed to long ITI was used, suggesting that it had a short time scale. In the second experiment, we controlled for effects of feature repetition and contingency learning, and replicated an enhanced conflict adaptation effect when integral negative emotion was elicited and a short ITI was used. We interpret these new results against a standard cognitive control framework assuming that integral negative emotion amplifies specific control signals transiently, and in turn enhances conflict adaptation. 相似文献

From a longitudinal study, we have repeatedly measured data from multiple individuals at multiple occasions. For each individual, the relation between 2 variables can be measured by the Pearson’s correlation. The question is how to aggregate the multiple correlations and conduct statistical inference on the aggregated intra-individual correlation. Several methods are proposed to aggregate and test intra-individual correlations: (a) a meta-analysis method based on Fisher’s Z transformed correlations, (b) a meta-analysis method based on the Pearson’s correlations, and (c) a multilevel modeling method using data standardized within each individual. The performance of the methods after bias corrections was compared using simulations with considering factors including numbers of individuals, numbers of time points, population effect sizes, and their distribution forms (homogeneous vs heterogeneous). The results from the simulation studies show that estimation biases were found using the meta-analytic methods and suggestions on when and how to correct biases were provided based on the simulation results. Furthermore, the performance of the 3 methods after necessary bias corrections was found to be comparable and reasonably good, indicating that all 3 methods worked for aggregating and testing intra-individual correlations. An empirical daily diary data set was then used to illustrate the applications of the 3 methods. The assumptions, advantages and disadvantages, and possible extensions of the 3 methods were discussed. 相似文献

Written emotional disclosure has been reported to confer a variety of benefits on physical and psychological well-being. However, variable findings suggest that outcomes may vary systematically as a function of specific parameters of the experimental design. This study aims to investigate the unique and combined effects of disclosure instructions focusing on emotional expression and instructions facilitating cognitive reappraisal and to examine how ambivalence over emotional expression and ethnicity moderate the effects of these writing instructions. Seventy-one Asian and 59 Caucasian undergraduates (N = 130) with at least minimal physical or depressive symptoms were randomly assigned to one of the four writing conditions: emotional disclosure (ED), cognitive reappraisal (COG), the combination of ED and COG, or a control condition. Self-reported physical symptoms, positive affect (PA) and negative affect were assessed at baseline and three follow-ups spanning 4 months. Mixed linear models revealed that COG writing reduced physical symptoms, ED buffered a decrease in PA over time, and the combination of ED and COG (i.e. self-regulation; SR) was most effective. Asians and highly ambivalent participants benefited most from expressive writing. Findings contribute to the development of a SR moderator model and carry implications for designing expressive disclosure studies, particularly for ethnic minorities. 相似文献

A key challenge in the fabrication of superhard nanocomposite films is how to control the distribution of grain sizes in these materials. High-resolution transmission electron microscopy has been used to measure nanograin-size distributions in the Ti–B–N films with various B contents. The results show that the mean grain size decreases with increase of B content and the grain-size distribution conforms to a log-normal function when the hardness approaches a maximum value. The transition from normal to log-normal distributions can be determined by analysis in terms of a minimum information criterion. The origin of a log-normal size distribution probably results from heterogeneity arising from a diffusion-drift process. 相似文献

功能核磁共振成像技术在探讨欺骗机制和开发测谎技术中的应用是目前的研究热点,前者使用多种范式来考察假装失忆、故意错误及人际交互中的欺骗行为的认知和神经机制,而后者主要沿用传统的GKT和CQT范式检测欺骗行为。已有研究突显了前额叶和顶叶这些参与执行控制过程的脑区在欺骗中的核心作用,但基于这些脑区信号进行测谎时,得到的准确率不容乐观。未来研究应探索除执行控制过程外的欺骗的其它认知成分,尝试从"记忆痕迹"和"欺骗结果"等方面寻找测谎的新线索。并应揭示"欺骗特质"的神经基础,以启发"忠诚度"的测量方法。 相似文献

近几年,风水术又流行起来。风水先生不足论,在一些学者的言论和论著中,也把风水说成是建筑选址的“环境科学”,比如要依山傍水,背风向阳之类。笔者经过对历史文献的考察,发现这完全是一种误解。兹将结果发表,供有关人士参考。一、风水术不是孔孟老庄及其以前的传统选择适当的地方做窝,是许多动物的本能。据研究,有些动物还有选择葬地的行为。到该死的时 相似文献
