Social Affiliation from Religious Disaffiliation: Evidence of Selective Mixing Among Youth with No Religious Preference During the Transition to College 下载免费PDF全文
Brandon Sepulvado David Hachen Michael Penta Omar Lizardo 《Journal for the scientific study of religion》2015,54(4):833-841
The number of individuals claiming a nonreligious identity in the United States is on the rise, with one‐fourth of the overall U.S. public failing to identify with any of the major religious traditions. In this article, we examine whether religious disaffiliation structures social network formation in a social context in which religious identification (and religiosity) is a salient cultural marker. We take advantage of unique data on the personal networks of youth transitioning into a college where religion is a culturally salient facet of everyday life. We hypothesize that, if there is nonreligious homophily, it may result from an attraction of the disaffiliated to each other or from a repulsion away from the religiously affiliated. Results of exponential random graph models suggest that both mechanisms may be at play. We find that religious “Nones” and affiliated non‐Catholics are disproportionately more likely to form and maintain relationships with one another and are relatively less likely to form and maintain relationships with members of their respective religious out‐groups. We close by outlining the implications of our findings and delineating promising avenues for future research. 相似文献

The current set of studies was designed to test a new credibility assessment tool, the Psychologically Based Credibility Assessment Tool (PBCAT). Participants watched lab-generated videos of true and false alibi statements, provided while under varying degrees of cognitive load. Judges either provided a truth/lie judgment only, or also rated 11 behavioral cues on the PBCAT. When stories were told under cognitive load the effectiveness of cues at discriminating truth/deception was enhanced, with targets under higher load judged more accurately. Results regarding the new assessment tool indicate that it is capable of improving deception detection performance, even with minimally trained, nonexpert observers. 相似文献

This study examined the effectiveness of a universal school-based prevention program that was designed to increase coping resources in preadolescents through the modeling and teaching of optimistic thinking skills. School psychologists, together with classroom teachers, implemented an eight-week program in eight Year 5 and 6 class groups as part of the regular school curricula. One hundred and sixty children who participated in the program were compared to 135 children in 8 control groups on pre- and post-test questionnaires. Post-test responses show that children who participated in the program reported significant improvements in coping efficacy, and reductions in depressive attributions and use of the non-productive coping strategies of worry, wishful thinking, not coping, and ignoring the problem when compared to controls. These results support the feasibility of implementing low-cost, non-intrusive programs in school settings that address the emotional health of all young people. Support is also provided for theories that suggest attributions for events and coping efficacy influence the selection of coping strategies. 相似文献

Using pharmacological approaches, others have suggested that L-type voltage-gated calcium channels (L-VGCCs) mediate both consolidation and extinction of conditioned fear. In the absence of L-VGCC isoform-specific antagonists, we have begun to investigate the subtype-specific role of LVGCCs in consolidation and extinction of conditioned fear using a molecular genetics approach. Previously, we used this approach to demonstrate that the Ca(v)1.3 isoform mediates consolidation, but not extinction, of contextually conditioned fear. Here, we used mice in which the gene for the L-VGCC pore-forming subunit Ca(v)1.2 was conditionally deleted in forebrain excitatory neurons (Ca(v)1.2(cKO) mice) to address the role of Ca(v)1.2 in consolidation and extinction of conditioned fear. We demonstrate that Ca(v)1.2(cKO) mice consolidate and extinguish conditioned fear as well as control littermates. These data suggest that Ca(v)1.2 is not critical for these processes and together with our previous data argue against a role for either of the brain-expressed L-VGCCs (Ca(v)1.2 or Ca(v)1.3) in extinction of conditioned fear. Additionally, we present data demonstrating that the L-VGCC antagonist nifedipine, which has been used in previous conditioned fear extinction studies, impairs locomotion, and induces an aversive state. We further demonstrate that this aversive state can enter into associations with conditioned stimuli that are present at the time that it is experienced, suggesting that previous studies using nifedipine were likely confounded by drug toxicity. Taken together, our genetic and pharmacological data argue against a role for Ca(v)1.2 in consolidation of conditioned fear as well as a role for L-VGCCs in extinction of conditioned fear. 相似文献

Tobacco smoking has been associated with the development and exacerbation of chronically painful conditions. Conversely, there is reason to believe that smokers may be motivated to use tobacco as a means of coping with their pain. To date, no controlled, experimental studies have tested for a causal relationship between pain and smoking motivation. The primary aim of the current study was to test the hypothesis that laboratory-induced cold pressor pain would enhance smoking motivation, as measured by self-reported urge to smoke and observation of immediate smoking behavior. Smokers (N=132) were randomly assigned to either pain or no pain conditions. Results indicated that situational pain increased urge ratings and produced shorter latencies to smoke. The relationship between pain and increased urge to smoke was partially mediated by pain-induced negative affect. The relationship between pain and shorter latency to smoke was fully mediated by pain-induced urge to smoke. This study provides the 1st experimental evidence that situational pain can be a potent motivator of smoking. 相似文献

Although several theories assert that understanding the search for meaning in life is important, empirical research on this construct is sparse. Three studies provide the first extensive effort to understand the correlates of the search for meaning in a multistudy research program. Assessed were relations between search for meaning and well-being, cognitive style, and the Big Five, Big Three, Approach/Avoidance, and Interest models of personality, with a particular emphasis on understanding the correlates of search for meaning that are independent of presence of meaning. Conceptual models of the relation between search and presence were tested. Findings suggest that people lacking meaning search for it; the search for meaning did not appear to lead to its presence. Study 3 found that basic motive dispositions moderated relations between search for meaning and its presence. Results highlight the importance of basic personality dispositions in understanding the search for meaning and its correlates. 相似文献

Contradicting evidence exists regarding the link between loneliness and sensitivity to facial cues of emotion, as loneliness has been related to better but also to worse performance on facial emotion recognition tasks. This study aims to contribute to this debate and extends previous work by (a) focusing on both accuracy and sensitivity to detecting positive and negative expressions, (b) controlling for depressive symptoms and social anxiety, and (c) using an advanced emotion recognition task with videos of neutral adolescent faces gradually morphing into full-intensity expressions. Participants were 170 adolescents (49% boys; Mage?=?13.65 years) from rural, low-income schools. Results showed that loneliness was associated with increased sensitivity to happy, sad, and fear faces. When controlling for depressive symptoms and social anxiety, loneliness remained significantly associated with sensitivity to sad and fear faces. Together, these results suggest that lonely adolescents are vigilant to negative facial cues of emotion. 相似文献
