Based on the articles brought together for this special issue, this article proposes a transversal analysis and theoretical elaboration of the question of the uses of religious elements for meaning making and boundary work. In order to do so, we will first propose a sociocultural psychological perspective to examine meaning making dynamics. Second, we will apply a boundary work perspective, as recently developed in the social sciences, on the organization of religious differences. The first considers religious elements as resources that can be used by people to orient themselves in time and the social space, to interpret and guide action, and to create new forms of life. The second approach proposes an analysis of uses of religious stuff in order to understand how boundaries between groups are created, transgressed or dissolved as well as to explore the link between religion and power. Our argument is that the articulation of these two approaches can itself offer a rich theoretical frame to apprehend religions in contemporary society. 相似文献

People often draw trait inferences from the facial appearance of other people. We investigated the minimal conditions under which people make such inferences. In five experiments, each focusing on a specific trait judgment, we manipulated the exposure time of unfamiliar faces. Judgments made after a 100-ms exposure correlated highly with judgments made in the absence of time constraints, suggesting that this exposure time was sufficient for participants to form an impression. In fact, for all judgments-attractiveness, likeability, trustworthiness, competence, and aggressiveness-increased exposure time did not significantly increase the correlations. When exposure time increased from 100 to 500 ms, participants' judgments became more negative, response times for judgments decreased, and confidence in judgments increased. When exposure time increased from 500 to 1,000 ms, trait judgments and response times did not change significantly (with one exception), but confidence increased for some of the judgments; this result suggests that additional time may simply boost confidence in judgments. However, increased exposure time led to more differentiated person impressions. 相似文献

In this study, we analyzed the participation of the entorhinal cortex in extinction of a learned aversive response. Rats with infusion cannulae aimed to the entorhinal cortex were trained in a one-trial step-down inhibitory avoidance task (IA) and submitted to four consecutive daily test sessions without the footshock, a procedure that induced extinction of the conditioned response in control animals. When infused into the entorhinal cortex immediately after the first extinction session at doses able to block consolidation of IA memory, the NMDA receptor antagonist, AP5 (25 nmol/side), the inhibitor of protein synthesis anisomycin (300 nmol/side) and the inhibitor of CaMKII, KN-93 (10 nmol/side), but not the MEK1/2 inhibitor PD-98059 (5 nmol/side) hindered extinction of the IA response. The same results were obtained when the interval between the first and second test session was 48 instead of 24h. The data indicate that normal functionality of the NMDA receptors, together with CaMKII activity and protein synthesis are necessary in the entorhinal cortex at the time of the first test session to generate extinction. Our results also suggest that the ERK1/2 pathway does not play a role in this process. 相似文献

Adenosine A1 and A2A receptor agonists and antagonists have been reported to alter learning and memory. The aim of our study was to investigate the involvement of adenosinergic system in memory retrieval into posterior cingulate cortex (PCC) of Wistar rats. To clarify this question, we tested specifics agonist and antagonists of adenosine A1 and A2A receptors in rats submitted to a one-trial inhibitory avoidance task. The stimulation of adenosine A1 and A2A receptors by CPA and CGS21680, respectively, impaired memory retrieval for inhibitory avoidance task, into PCC. These findings provide behavioral evidence for the role of adenosinergic system in the memory retrieval into PCC. 相似文献

An object in continuous motion is perceived ahead of the briefly flashed object, although the two images are physically aligned (Nijhawan, 1994), the phenomenon called flash-lag effect. Flash-lag effects have been found also with other continuously changing features such as color, pattern entropy, and brightness (Sheth, Nijhawan, & Shimojo, 2000) as well as with streamed pre- and post-target input without any change of the feature values of streaming items in feature space (Bachmann & P?der, 2001a. 2001b). We interpret all instances of the flash-lag as a consequence of a more fundamental property of conscious perception in general: acceleration of the speed with which samples of perceptual information become represented in explicit format immediately after the stimulation onset. Decreased visual latency of the samples of stimulus information from the streamed input leads to the relative perceptual lag for the separately flashed stimulus because it is not preceded by adjacent sensory input that would have accelerated its perception. Experimental support for the notion of perceptual acceleration is reviewed. 相似文献

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings. 相似文献

The effects of aging on judgments of short temporal durations were explored using the prospective paradigm and the methods of verbal estimation and production. Younger and older adults performed a perceptual judgment task at five levels of complexity for periods of 30, 60, and 120 sec. Participants either continued to perform the task for a specified interval (production) or were stopped and then verbally estimated the interval. Older adults gave shorter verbal estimates and longer productions than did younger adults. The methods of verbal estimation and production yielded approximately equal duration judgment ratios once range effects were taken into account. Task complexity had little effect. The major conclusion is that duration judgment ratios decrease from younger to older adults when the intervals are filled with a mental task. 相似文献

Illness irreversibly alters our lives and our relationships. More than a physical or psychological experience, the passage
of illness is an existential crisis that is potentially transformative for an individual and his or her loved ones. It is
through ritual enactment that we can most fully experience the transformative potential of illness. Rituals are common during
illness, but are underutilized for the critically-important reintegration period following acute illness, when personal, interpersonal,
and communal healing must occur. Pastoral counselors and others who comfort and counsel the sick and their loved ones should
encourage religious and secular ritual enactment to ease this passage. 相似文献

Early parent–child conversations about past emotional experiences provide a rich environment for the socialization of emotions. This study explored the role of parent and child gender in this process. Participants were 21 White, middle-class, 40- to 45-month-old children and their mothers and fathers. At separate home visits, each parent discussed with their child four specific past events during which the child experienced happiness, anger, sadness, and fear, respectively. Mothers conversed more overall, talked more about emotional aspects of the experience, and used more emotion words than did fathers. Similarly, girls talked more about emotional aspects of their experiences than did boys. Further, girls used more emotion words when discussing scary events than did boys. Most intriguingly, both mothers and fathers used more emotional utterances when discussing sad events with daughters than with sons. Parent–daughter dyads also placed emotional experiences in a more interpersonal context than did parent–son dyads. Implications for the development of gender, emotional understanding, and clinical repercussions are discussed. 相似文献
