This paper examines the activities of churches in Baltimore, Maryland, concerning the issues of sexuality, whether they potentially stigmatize persons with or at risk for HIV/AIDS, and to what extent individual agency versus institutional forces influence churches in this regard. In-depth interviews were conducted with 20 leaders from 16 churches and analyzed using a grounded theory methodology. Although many churches were involved in HIV/AIDS-related activities, the content of such initiatives was sometimes limited due to organizational constraints. Church leaders varied, however, in the extent to which they responded in accordance with or resisted these constraints, highlighting the importance of individual agency influencing churches?? responses to HIV/AIDS. 相似文献

This study used event-related potentials to explore whether mind wandering (task-unrelated thought, or TUT) emerges through general problems in distraction, deficits of task-relevant processing (the executive-function view), or a general reduction in attention to external events regardless of their relevance (the decoupling hypothesis). Twenty-five participants performed a visual oddball task, in which they were required to differentiate between a rare target stimulus (to measure task-relevant processes), a rare novel stimulus (to measure distractor processing), and a frequent nontarget stimulus. TUT was measured immediately following task performance using a validated retrospective measure. High levels of TUT were associated with a reduction in cortical processing of task-relevant events and distractor stimuli. These data contradict the suggestion that mind wandering is associated with distraction problems or specific deficits in task-relevant processes. Instead, the data are consistent with the decoupling hypothesis: that TUT dampens the processing of sensory information irrespective of that information's task relevance. 相似文献

The first candidate gene studies of human personality promised much but, in the fifteen years since their publication, have delivered little in the way of clear evidence for the contribution of specific genetic variants to observed variation in personality traits. This is most likely due to the very small effects conferred by individual loci. The advent of genome-wide association studies has brought growing awareness that high levels of statistical stringency, very large sample sizes, and independent replication will be minimum requirements for future genetic studies of personality. At the same time, evidence from other fields indicates that the genetic architecture of personality is likely to consist of the combined effect of many hundreds, if not thousands, of small effect loci. 相似文献

Extensive work over the past decade has shown that race can bias perceptions and responses to threat. However, the previous work focused almost exclusively on responses to men and overlooked how gender and the interaction of race and gender influence decisions regarding use of force. In the current article, two studies examine the implications of gender (Study 1) and both race and gender (Study 2) for decisions to shoot criminal suspects on a computerized simulation. In Study 1, participants were biased away from shooting White female suspects compared to White male suspects. In Study 2, White participants showed a pronounced bias toward shooting Black men but a bias away from shooting Black women and White ingroup members, providing evidence of a behavioral threat-related response specific to outgroup men stereotypically associated with aggression. The theoretical and practical implications of these findings are discussed. 相似文献

An important dimension of cognitive control is the adaptive regulation of the balance between exploitation (pursuing known
sources of reward) and exploration (seeking new ones) in response to changes in task utility. Recent studies have suggested
that the locus coeruleus-norepinephrine system may play an important role in this function and that pupil diameter can be
used to index locus coeruleus activity. On the basis of this, we reasoned that pupil diameter may correlate closely with control
state and associated changes in behavior. Specifically, we predicted that increases in baseline pupil diameter would be associated
with decreases in task utility and disengagement from the task (exploration), whereas reduced baseline diameter (but increases
in task-evoked dilations) would be associated with task engagement (exploitation). Findings in three experiments were consistent
with these predictions, suggesting that pupillometry may be useful as an index of both control state and, indirectly, locus
coeruleus function. 相似文献

Affective Intelligence (AI) theory proposes to answer a fundamental question about democracy: how it succeeds even though most citizens pay little attention to politics. AI contends that, when circumstances generate sufficient anxiety, citizens make informed and thoughtful political decisions. In Ladd and Lenz (2008 ), we showed that two simpler depictions of anxiety's role can explain the vote interactions that apparently support AI. Here, we again replicate Marcus, Neuman and MacKuen's (2000 )'s voting model, which they contend supports AI, and again show that it is vulnerable to these alternative explanations, regardless of how candidate choice is measured. We also briefly review the broader literature and discuss Brader's (2005, 2006 ) important experimental results. Although the literature undoubtedly supports other aspects of AI, few studies directly test AI's voting claims, which were the focus of our reassessment. In our view, the only study that does so while ruling out the two alternatives is our analysis of the 1980 ANES Major Panel ( Ladd & Lenz, 2008 ), which finds no support for AI, but ample support for the alternatives. None of the responses to Ladd and Lenz (2008 ) addresses these findings. Overall, evidence that anxiety helps solve the problem of voter competence remains sparse and vulnerable to alternative explanations. 相似文献

I argue that the aporetic character of clemency must be understood in terms of its unmerited and merited character to achieve the underlying purposes of justice within criminal justice: justice as fairness (punishment must be deserved and proportionate) and justice as restoration (repair of the harm to victims and society and the reintegration of offenders) are paramount goals. Rather than destabilizing political order, pardons can render productive potential tensions between justice as fairness and justice as restoration. Taking as my conceptual point of departure Paul Ricoeur's claims about the suprajuridical and supraethical character of pardon, I develop the argument through three central sections: an excursus into historical and contemporary practices of clemency in the United States; a critical analysis of the merited and unmerited aspects of clemency with respect to remorse and atonement theories within theological and legal discourse; and a normative engagement with pardons and felony disenfranchisement. 相似文献

Three lexical decision experiments in French investigated the effects of briefly presented forward-masked non-word primes on latencies to phonologically and/or orthographically related targets. At 64-msec prime presentation durations, primes that are pseudohomophones of the target produced facilitatory effects compared to orthographic controls, but these orthographically similar non-word primes did not facilitate target recognition compared to unrelated controls. These results were obtained independently of target word frequency and independently of the presence or absence of pseudohomophone targets in the experimental lists. With a 32-msec prime duration, on the other hand, pseudohomophone and orthographic primes had similar effects on target recognition, both producing facilitation relative to unrelated controls. The results are discussed in terms of the time course of phonological and orthographic code activation in the processing of pronounceable strings of letters. 相似文献
