Muslim Americans are increasingly integrated into American life, displaying high socioeconomic status, political participation, and adherence to American values. However, they are evaluated more negatively than many other racial, ethnic, and religious minorities and are frequent targets of discrimination. This article examines the mismatch between the integration of Muslims and their poor reception. Drawing on theories of cultural fluency and cognitive dissonance, we argue that cultural integration can exacerbate, rather than mitigate, perceived discrimination because integrated individuals are socialized to expect fair treatment and can recognize and decode even subtle forms of discrimination due to high levels of cultural and language fluency. Using three nationally representative surveys and an opt-in, online study of American Muslims between 2007 and 2017, we find that integrated Muslims are consistently more likely than their counterparts to report individual- and group-level societal and political discrimination. The paradox between adopting the host culture and feeling marginalized poses a challenge to the assumption that integration naturally leads to a sense of belonging among minorities, with important implications for liberal democracies.  相似文献

Researchers have paid almost no attention to the narrative comments that typically accompany multirater feedback reports despite the fact that both anecdotal and empirical evidence suggest that feedback recipients devote considerable attention to such comments. The authors examined improvement in upward feedback ratings over a 1-year period for 176 managers as a function of (a) the number of narrative comments each manager received, (b) whether those comments were favorable (vs. unfavorable), and (c) whether the comments were behavior/task focused (vs. trait focused). The authors found that managers who received a small number of unfavorable, behavior/task-focused comments improved more than did other managers, whereas managers who received a large number of unfavorable, behavior/task-focused comments declined more than did other managers.  相似文献

Sleep-dependent learning and motor-skill complexity   总被引:4,自引:0,他引:4       下载免费PDF全文
Learning of a procedural motor-skill task is known to progress through a series of unique memory stages. Performance initially improves during training, and continues to improve, without further rehearsal, across subsequent periods of sleep. Here, we investigate how this delayed sleep-dependent learning is affected when the task characteristics are varied across several degrees of difficulty, and whether this improvement differentially enhances individual transitions of the motor-sequence pattern being learned. We report that subjects show similar overnight improvements in speed whether learning a five-element unimanual sequence (17.7% improvement), a nine-element unimanual sequence (20.2%), or a five-element bimanual sequence (17.5%), but show markedly increased overnight improvement (28.9%) with a nine-element bimanual sequence. In addition, individual transitions within the motor-sequence pattern that appeared most difficult at the end of training showed a significant 17.8% increase in speed overnight, whereas those transitions that were performed most rapidly at the end of training showed only a non-significant 1.4% improvement. Together, these findings suggest that the sleep-dependent learning process selectively provides maximum benefit to motor-skill procedures that proved to be most difficult prior to sleep.  相似文献

Schizotypal personality disorder is characterized by interpersonal and verbal communication deficits. Despite the important role of gesture in social communication, no published reports examine the use of gesture by individuals with SPD. In this study, raters code gesture from videotaped interviews of unmedicated adolescents with SPD, other personality disorders, or no Axis II disorder. Results indicate that SPD adolescents show significantly fewer gestures but do not differ from the other groups in overall rate of movement. The findings are discussed in light of brain regions involved in dysfunction, parallels to schizophrenia, and treatment implications.  相似文献

Little is known about the affective features of acculturative stress or its relation to attributional styles for negative events. The authors examined associations among acculturative stress, attributional style, and positive and negative affect among 96 ethnic minority college students. They hypothesized that acculturative stress would be characterized by elevated negative affect and global and stable attributions for negative events. Consistent with prediction, acculturative stress was significantly associated with negative affect and global attributions, even when controlling for other relevant predictors. Attributional style did not account for the association between negative affect and acculturative stress. Positive affect and stable and internal attributional styles were not related to acculturative stress. The authors discuss implications for reducing stress associated with acculturation.  相似文献

In two studies people judged the order in which two real-world events occurred. Ordering performance was better for events that were recent or widely separated in time. Ordering performance was also consistently related to predicted event memorability and to the amount of processing given to an event during encoding. Ordering performance was not consistently related to the person-typicality, pleasantness, or emotional intensity of the events, and was also not related to whether the two events judged came from the same thematic category. These results suggest that memory for event order is not entirely reconstructed from event content. We suggest that the self-concept may sometimes serve as an implicit timekeeper in autobiographical memory.  相似文献

A lack of information about disease in children can lead to erroneous views such as children believing that hospital admittance or the presence of a disease is a punishment for a perceived wrong. There has thus far been no standard tool available to measure children's illness conceptualizations from a Leventhalian framework. Three groups of children with eczema, asthma and eczema and asthma between the ages of 7 and 12 years of age were recruited. Children were given the Children's Illness Perception Questionnaire (CIPQ), a 26-item instrument adapted from the Illness Perception Questionnaire for adults. A Kuder - Richardson 20 test of reliability for dichotomous data was performed allowing an estimate of the internal consistency of the measurement scales. It can be seen that, for all three illness groups, internal consistency is acceptable for the timeline and consequences scale. The cure/control scale, however, was not internally consistent for any illness group. As health professionals, we need to develop the means to further understand how paediatric illness beliefs relate to specific disease types, age and psychosocial factors and the utility of this instrument is discussed within this context.  相似文献

Reduced hypothalamic-pituitary-adrenal (HPA) responses to stress during the last week of pregnancy and lactation have been consistently observed in rat studies. Several contributing factors have been proposed for this phenomenon in lactation, including the suckling stimulus from the pups, hormones (oxytocin and prolactin) and opioids, a decrease in the ability of noradrenaline to potentiate hypothalamic responses and changes in pituitary responsiveness to ACTH secretagogues (AVP and CRF). In contrast to this vast literature using the rat model, only few studies have addressed this issue in the human population. The consensus is that women engaging in breastfeeding activities exhibit reduced anxiety, although the reductions in neuroendocrine and autonomic responses to stressors are variable, in part because of the different nature of the stressors used. Further work is required to investigate how additional factors, such as maternal parity or emotional salience of the stressor can affect stress responsiveness in postpartum women. Here, we review first the findings regarding stress responsiveness during lactation in both rat and human studies, and then discuss potential research avenues and methodological issues that could be the lead to future research protocols in human subjects. Knowing the reciprocal relationship in the mother-infant dyad, it is clear that investigation of the mechanisms regulating stress responses and mental health in postpartum mothers can only be beneficial to the development of the infant.  相似文献
