The majority of Americans identify themselves as belonging to some religious group. There is a mixed body of literature on whether or not religious affiliation has an influence on engaging in risky behaviors among young adults attending college. This study examined associations between religious affiliation, risky sexual practices, substance use, and family structure among a sample of predominantly white college females attending a southeastern university. Given the high risk of acquiring genital human papillomavirus infection as a result of high risk sexual practices, gaining a better understanding of how religious affiliation can be used to promote healthy sexual behaviors is warranted. 相似文献

Influential models highlight the central integration of bodily arousal with emotion. Some emotions, notably disgust, are more closely coupled to visceral state than others. Cardiac baroreceptors, activated at systole within each cardiac cycle, provide short-term visceral feedback. Here we explored how phasic baroreceptor activation may alter the appraisal of brief emotional stimuli and consequent cardiovascular reactions. We used functional MRI (fMRI) to measure brain responses to emotional face stimuli presented before and during cardiac systole. We observed that the processing of emotional stimuli was altered by concurrent natural baroreceptor activation. Specifically, facial expressions of disgust were judged as more intense when presented at systole, and rebound heart rate increases were attenuated after expressions of disgust and happiness. Neural activity within prefrontal cortex correlated with emotionality ratings. Activity within periaqueductal gray matter reflected both emotional ratings and their interaction with cardiac timing. Activity within regions including prefrontal and visual cortices correlated with increases in heart rate evoked by the face stimuli, while orbitofrontal activity reflected both evoked heart rate change and its interaction with cardiac timing. Our findings demonstrate that momentary physiological fluctuations in cardiovascular afferent information (1) influence specific emotional judgments, mediated through regions including the periaqueductal gray matter, and (2) shape evoked autonomic responses through engagement of orbitofrontal cortex. Together these findings highlight the close coupling of visceral and emotional processes and identify neural regions mediating bodily state influences on affective judgment. 相似文献

According to Botvinick’s (2007) integrative account, conflict monitoring is aversive because individuals anticipate cognitive demand, whereas the revised
reinforcement sensitivity theory (rRST) predicts that conflict processing is aversive because individuals anticipate aversive
reinforcement of erroneous responses. Because these accounts give different reasons for the aversive aspects of conflict,
we manipulated cognitive demand and the aversive reinforcement as a consequence of wrong choices in a go/no-go task. Thereby,
we also aimed to investigate whether individual differences in conflict sensitivity (i.e., in trait anxiety, linked to high
sensitivity of the behavioral inhibition system [trait-BIS]) represent the effects of aversive reinforcement and cognitive
demand in conflict tasks. We expected that these manipulations would have effects on the frontal N2 component representing
activity of the anterior cingulate cortex. Moreover, higher-trait-BIS individuals should be more sensitive than lower-trait-BIS
individuals to aversive effects in conflict situations, resulting in a more negative frontal N2 for higher-trait-BIS individuals.
In Study 1, with N = 104 students, and Study 2, with N = 47 students, aversive reinforcement was manipulated in three levels (within-subjects factor) and cognitive demand in two
levels (between-subjects factor). The behavioral findings from the go/no-go task with noncounterbalanced reinforcement levels
(Study 1) could be widely replicated in a task with counterbalanced reinforcement levels (Study 2). The frontal mean no-go
N2 amplitude and the frontal no-go N2 dipole captured predicted reinforcement-related variations of conflict monitoring, indicating
that the anticipation of aversive reinforcement induces variations in conflict monitoring intensity in frontal brain areas.
The aversive nature of conflict was underlined by the more pronounced conflict monitoring in higher- than in lower-trait-BIS
individuals. 相似文献

Three studies examined the relative valence and strength of implicit attitudes toward Arab-Muslims using the Implicit Association Test (IAT) while exploring the moderation of such implicit effects. Studies have suggested that repeated exposure to information associating members of a social group (e.g., Arab-Muslims) with evaluative attributes (e.g., terrorism) might create automatic attitudes toward them. Consistent with this notion, the IAT results indicated strong implicit preference for White over Arab-Muslim, whereas the magnitude of such a bias was substantially diminished when assessed by explicit measures (Study 1). It is also interesting to note that participants exhibited implicit preference for Black over Arab-Muslim when measured by the IAT, whereas no difference was found between the 2 groups in stimulus familiarity and in explicit attitudes (Studies 2 and 3). However, such implicit effects were moderated when participants were exposed to positive information about Arab-Muslims (Study 3). Theoretical and practical implications of these findings are further discussed. 相似文献

AbstractThe aim of this paper is to identify what I take to be the main conceptual problem in Lewis’ semantics for counterfactuals when the Limit Assumption (LA) is not satisfied, what I call the Discrimination Problem (DP), and to present and discuss a modification of Lewis’ semantics that aims at solving DP. First, I outline Lewis’ semantics, highlighting the aspects that will be relevant for our discussion. Second, I present DP and discuss it with a heuristic example. Third, I present the new proposal and comment some formal consequences and the objections they give rise to. Fourth, I present an allegedly equivalent version of the proposal and discuss the difference between counterfactuals and strict conditionals. Finally, I defend that the two proposals are different and argue for the first one as the best way of capturing two intuitions that seem in conflict when the LA is not satisfied. I conclude with a dilemma: either the proposal here defended works or LA is inescapable. Thus, if the proposal doesn’t work, the paper must then be considered as an indirect defense of the Limit Assumption. 相似文献

In this article, we look at the recent introduction of more relational-oriented learning principles and how they translate into practice by documenting the experiences of both trainees and instructors. It became clear that actors held different opinions and viewpoints on learning objectives and process ingredients for achieving these objectives. This divergence in opinions resulted in an “impoverished” learning trajectory. We suggest that remedying this situation implies introducing reflexivity regarding learning processes or, stated otherwise, addressing “meta-cognitions” that participants inevitably bring to the process as they affect the way in which people engage in the relational field that encompasses the learning trajectory. Despite some recent arguments in favour of a distinction between cognitive and meta-cognitive mediation, we argue for a similar approach with respect to both types of mediation. We end this article by suggesting that designing learning trajectories with this dual concern in mind might open the road to “learning to learn”. 相似文献

ABSTRACT Prospective memory involves remembering to perform intended actions in the future. Previous work with the multinomial model of event-based prospective memory indicated that adult age-related differences in prospective-memory performance were due to the prospective (not the retrospective) component of the task (Smith & Bayen, 2006, Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 623). However, ongoing-task performance was also lower in older adults in that study. In the current study with young and older adults, the difficulty of the ongoing task was manipulated by varying the number of colors per trial to create easier and harder versions of the ongoing task for each age group. The easier version included 2 colors per trial for older adults and 4 colors for young adults. The harder version included 4 colors for older adults and 6 colors for young adults. By adjusting the ongoing-task difficulty, older adults were able to perform the ongoing task as well or better than the young adults. Analyses with the multinomial model revealed that making the ongoing task easier for older adults (or more difficult for young adults) did not eliminate age-related differences in prospective-memory performance and the underlying prospective component. 相似文献
