Four studies investigated the conditions under which minority group members respond to group‐based discrimination with increased identification with their group. We propose that minorities' interaction goals should serve as a moderator: seeking distance from the majority might keep minority identification alive in the face of perceived discrimination. These predictions were tested correlationally in Study 1 among Chinese immigrants in Australia (sample 1a) and children of rural migrant workers in a Chinese city (sample 1b). In Studies 2 and 3, perceived discrimination was manipulated among Romanian immigrants in France and Polish immigrants in Scotland. In Study 4, both minority goals and perceived discrimination were manipulated among a sample of international students in Australia. Results showed that only for those who were inclined to seek distance from the majority, minority group identification increased when discrimination was high compared with low. Discussion focuses on the way that seeking distance might be an important strategy for coping with discrimination. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents’ friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends’ engagement in NSSI still significantly predicted adolescents’ own engagement in NSSI. Adolescents’ friendship groups’ NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI. 相似文献

This study examined how different components of working memory are involved in the acquisition of egocentric and allocentric survey knowledge by people with a good and poor sense of direction (SOD). We employed a dual‐task method and asked participants to learn routes from videos with verbal, visual, and spatial interference tasks and without any interference. Results showed that people with a good SOD encoded and integrated knowledge about landmarks and routes into egocentric survey knowledge in verbal and spatial working memory, which is then transformed into allocentric survey knowledge with the support of all three components, distances being processed in verbal and spatial working memory and directions in visual and spatial working memory. In contrast, people with a poor SOD relied on verbal working memory and lacked spatial processing, thus failing to acquire accurate survey knowledge. Based on the results, a possible model for explaining individual differences in spatial knowledge acquisition is proposed. 相似文献

本研究根据音乐加工的层级结构, 对现有的脑成像研究进行了元分析, 探讨了音乐知觉的神经基础。具体而言, 对特异于音乐知觉加工的两个层级, 音程分析和结构分析的神经基础进行了分析, 并在此基础上对比了参与两个层级加工的脑区。结果发现, 音程分析主要的激活分布在双侧颞上回和右侧额下回, 在中央前回、角回和脑岛等脑区也有分布。音程分析在颞上回激活最多, 可能表明颞上回为音程分析的核心区域。结构分析激活分布较广, 主要激活颞上回、颞横回和前额叶区域, 此外, 还激活了下顶叶、缘上回和舌回等顶枕区域。结构分析在前额叶激活最多, 可能表明前额叶为结构分析的核心区域。最后, 对比两层级激活的脑区发现, 二者仅在后侧颞上回存在着重合, 而在绝大部分脑区则表现出分离, 这暗示了音程分析和结构分析通过颞上回进行交流, 并负责音乐不同层面的加工。 相似文献

Attention is a complex domain that has reawakened research interest in recent years. There are relatively few studies that have examined age-related changes across different attention subcomponents, such as selection, maintenance, and control, using large samples covering a wide age range. The present study assessed performance in 466 participants in order to identify the ages at which mature performance was reached across differing attention subcomponents. Furthermore, we investigated whether the nature of the attentional demands or task difficulty predicted the age at which stable levels of performance were reached. The results supported the former rather than the latter alternative. 相似文献

The effect of chemical stresses upon the relation between extended dislocations and high-temperature creep in a thin plate has been investigated. The critical stress needed for the contraction of extended jogs and its effect on the creep rate are obtained. The results indicate that the critical stress needed for the contraction increases with decreasing stacking fault energy (SFE). However, creep occurs more easily with increasing SFE and increasing angle of the Burgers vector to the dislocation line, as well as with the concentration of any diffusing atoms. 相似文献

The crack-tip deformation behavior during a single overload, fatigue test of ferritic stainless steel, and Ni-based HAYNES 230 superalloy is studied at different structural levels using (1) neutron-diffraction, from which both the elastic-lattice strain and volume-averaged total dislocation densities are obtained, (2) polychromatic X-ray microdiffraction to probe the geometrically necessary dislocations and boundaries distribution, and (3) an irreversible and hysteretic cohesive interface model which has been implemented into a finite element framework to simulate the stress/strain evolution near the fatigue crack tip. Neutron strain measurements and finite element simulations are in qualitative agreement on the macroscopic length scale. Large plastic deformation induced by the overload and the resulting compressive residual strains are observed in front of the crack tip after the overload, and are the principal reason for the fatigue-crack-growth retardation. Strong strain gradients surrounding the crack propagation result in the formation of a high density of geometrically necessary dislocations near the fractured surface and cause local lattice rotations on the submicron level. 相似文献

Lead zirconate titanate (PZT) (Pb(Zr0.52Ti0.48)O3) and barium titanate (BaTiO3) thin films have been successfully prepared using a novel sol-gel- hydrothermal (SG-HT) technique at low temperatures, which involves a combination of the conventional sol-gel process and a hydrothermal method. Highly (111)-oriented PZT thin films with a single perovskite phase and polycrystalline BaTiO thin films with well developed crystallites were obtained at a processing temperature as low as 1600C. The microstructural characteristics demonstrate that the SG-HT-derived PZT and BaTiO3 thin films with good crystallinity and surface morphology are converted from the amorphous phase to the desired perovskite phase on platinum-coated and bare silicon substrates at a low processing temperature of 100-200 C. These results suggest that the SGHT technique, which is of great significance because of its low processing temperature, will become a potential and promising process for fabricating PZT, BaTiO3 and other oxide thin films. 相似文献

In November 2010, Maclean’s magazine published a provocative article “Too Asian?” which aroused hot debate and critique from various social groups. However, its racist nature and the role of media in reinforcing racial stereotypes, manufacturing consent, and naturalizing unequal power relations has not been examined in a systematic way. Using critical discourse analysis, this paper aims to reveal its ideological and hegemonic function in constructing unequal social identities and social relations which consequently prevents racialized minorities from accessing post-secondary educational opportunities. Four themes are identified and discussed here. First, the “Too Asian?” article reinforces an Us/Them division and a “forever foreigner” identity of racialized minorities. Second, it essentializes ethnic culture and identifies culture rather than structural constraints as an explanation for individual social behaviors. Third, it represents “Asian” students as self-segregationists who should be blamed for their own exclusion. Last, but most important, it aims to justify white privilege in the field of post-secondary education by questioning the idea of meritocracy as university admission criteria and suggests maintaining “WASP Credentials.” 相似文献
