This article explored the association between economic activity and the contribution to domestic labor in a Middle Eastern society. Analyses were carried out on cross-sectional survey data from 5,998 individuals, aged between 18 and 64 years, in three poor communities in the suburbs of Beirut, Lebanon. Domestic labor was evaluated with a composite index that takes into account both the type of task performed and the level of involvement. Housework categories included core household chores, care giving, financial management, home management, and home/car maintenance. Results showed that women continue to do most of the domestic labor in the three communities. However, women’s load of domestic labor decreased as they joined the labor market, whereas men’s contribution to domestic labor increased with involvement in paid work. Relatively speaking, the difference in contribution to housework between house members engaged and not engaged in paid labor was much higher for women than it was for men.  相似文献

Latino and White/European American children (N = 99; 5–11 years of age) participated in a study designed to examine their perceptions of racial/ethnic discrimination in educational settings. Children heard scenarios involving two children of different races/ethnicities, one who received a more positive outcome from a teacher than the other. Children were then asked about the reasons for the differential outcomes. The role of (a) situational information (i.e., the race/ethnicity of the children and teacher in the story, and information about the teacher's past choices); (b) social-cognitive abilities (i.e., theory of mind); and (c) child characteristics (i.e., child's race/ethnicity and racial/ethnic attitudes) in facilitating children's attributions to discrimination was assessed. Results indicated that children most frequently attributed differential outcomes to the quality of work or the ability of students. Children were most likely to make an attribution to discrimination when the teacher rewarded a same-race/ethnicity child and had a history of similar behavior. Children's attention to situational information was moderated, however, by their social-cognitive abilities. Children's own race/ethnicity and ethnic attitudes also affected their perceptions of discrimination.  相似文献

This is an examination of two essays on minimal religion by Mikhail Epstein (1982 and 1999), assessing the usefulness of the term ‘minimal religion’ for the analysis of religion in contemporary Russia. An adapted version of a paper delivered at the School of Slavonic and East European Studies (SSEES), University of London, on 8 December, 2003. Note regarding Mikhail Epstein’s use of the words ‘religion’, ‘religiosity’ and ‘spirituality’: Epstein uses the word ‘religion’ to signify ‘mainstream’, church-based manifestations of religion and also the institutional, hierarchical structures related to those. Although in English usage the word ‘religiosity’ has negative connotations – signifying either a superficially felt religious sentiment or a somehow false and insincere expression of religious feeling, intended for outward show – Epstein appears to use the term entirely neutrally. For him it simply serves as a synonym for the word ‘spirituality’. In the two essays examined in the present article the word ‘spirituality’ signifies the whole inner spiritual life and aspirations of the individual and her/his reflection on an ethical way of living, whether the person concerned is a committed, church-going believer, or someone engaged in a personal spiritual or philosophical quest for meaning, or else someone who has experienced what Epstein refers to as ‘the wilderness’ of the Soviet years and has learnt of a spiritual dimension to life through that formative experience.  相似文献

Beyond Fear Emotional Memory Mechanisms in the Human Brain   总被引:1,自引:0,他引:1  
ABSTRACT— Neurobiological accounts of emotional memory have been derived largely from animal models investigating the encoding and retention of memories for events that signal threat. This literature has implicated the amygdala, a structure in the brain's temporal lobe, in the learning and consolidation of fear memories. Its role in fear conditioning has been confirmed, but the human amygdala also interacts with cortical regions to mediate other aspects of emotional memory. These include the encoding and consolidation of pleasant and unpleasant arousing events into long-term memory, the narrowing of focus on central emotional information, the retrieval of prior emotional events and contexts, and the subjective experience of recollection and emotional intensity during retrieval. Along with other mechanisms that do not involve the amygdala, these functions ensure that significant life events leave a lasting impression in memory.  相似文献

Ordinality is – beyond numerical magnitude (i.e., quantity) – an important characteristic of the number system. There is converging empirical evidence that (intra)parietal brain regions mediate number magnitude processing. Furthermore, recent findings suggest that the human intraparietal sulcus (IPS) supports magnitude and ordinality in a domain-general way. However, the latter findings are derived from adult studies and with respect to children (i.e., developing brain systems) both the neural correlates of ordinality processing and the precise role of the IPS (domain-general vs. domain-specific) in ordinality processing are thus far unknown. The present study aims at filling this gap by employing functional magnetic resonance imaging (fMRI) to investigate numerical and non-numerical ordinality knowledge in children with and without developmental dyscalculia. In children (without DD) processing of numerical and non-numerical ordinality alike is supported by (intra)parietal cortex, thus extending the notion of a domain-general (intra)parietal cortex to developing brain systems. Moreover, activation extents in response to numerical ordinality processing differ significantly between children with and without dyscalculia in inferior parietal regions (supramarginal gyrus and IPS).  相似文献

The aim of the present study is to investigate the learning-related changes in brain activation induced by the training of hypothesis generation skills regarding biological phenomena. Eighteen undergraduate participants were scanned twice with functional magnetic resonance imaging (fMRI) before and after training over a period of 2 months. The experimental group underwent eight biological hypothesis generation training programs, but the control group was not given any during the 2-month period. The results showed that the left frontal gyri, the cingulate gyrus, and the cuneus were activated during hypothesis generation. In addition, the brain activation of the trained group increased in the left inferior and the superior frontal gyri, which are related to working memory load and higher-order inferential processes. However, the activation after training decreased in the occipito-parietal route, which is associated with the perception and the analysis processes of visual information. Furthermore, the results have suggested that the dorsolateral prefrontal cortex (DLPFC) region is the critical area in the training of hypothesis generation skills.  相似文献

Several studies have demonstrated that acquired expertise influences aesthetic judgments. In this paradigm we used functional magnetic resonance imaging (fMRI) to study aesthetic judgments of visually presented architectural stimuli and control-stimuli (faces) for a group of architects and a group of non-architects. This design allowed us to test whether level of expertise modulates neural activity in brain areas associated with either perceptual processing, memory, or reward processing. We show that experts and non-experts recruit bilateral medial orbitofrontal cortex (OFC) and subcallosal cingulate gyrus differentially during aesthetic judgment, even in the absence of behavioural aesthetic rating differences between experts and non-experts. By contrast, activity in nucleus accumbens (NAcc) exhibits a differential response profile compared to OFC and subcallosal cingulate gyrus, suggesting a dissociable role between these regions in the reward processing of expertise. Finally, categorical responses (irrespective of aesthetic ratings) resulted in expertise effects in memory-related areas such as hippocampus and precuneus. These results highlight the fact that expertise not only modulates cognitive processing, but also modulates the response in reward related brain areas.  相似文献

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.  相似文献

采用相对新近性判断范式(judgments of relative recency),通过三个实验探讨了工作记忆中时序信息和空间信息的存储方式及其关系。实验一比较了有无空间线索两种条件下时序信息的记忆绩效,结果发现,有无空间线索并不影响对时序信.E-的记忆。实验二和实验三通过控制刺激呈现的视野范围和减少呈现位置的不确定性来利化空间线索,结果表明,时序信息的记忆绩效也不受空间线索的影响。由此推论,工作记忆中的时序信息和空间信息是分离编码存储的,加入空间线索并不能提高时序信息的记忆绩效。  相似文献
