The purpose of this study was to examine individual differences in the activation and regulation of the hypothalamic-pituitary-adrenal (HPA) axis in prepubertal children after exposure to two different stress modalities and to evaluate the utility of an individual differences approach to the examination of HPA axis functioning. After a 30-min controlled baseline period, 73 7-year-olds (40 boys and 33 girls) were randomly assigned to a validity check condition or one of two experimental tasks designed to elicit fear or frustration. This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples were collected, including 12 poststress samples at 5-min intervals. There was a significant stress modality effect, with children exposed to the fear condition reaching peak cortisol levels at 25 min poststress and those exposed to the frustration condition reaching peak levels at 45 min poststress. There was no difference in peak cortisol levels between the stress modalities. Individual variability across conditions was significant, with participants reaching peak levels as early as 10 min poststress and as late as 60 min poststress. Our data suggest that analysis of individual curves prior to making group-level comparisons may improve the explanatory power of HPA axis behavior models. 相似文献

This paper reports the findings of two field studies of Australian drivers in which individual differences in stress and fatigue were investigated. In the first study, 58 professional drivers completed measures of mood, fatigue and other subjective stress state measures, before and after performing a prolonged driving trip. The results indicated that the scales were sensitive to increased fatigue following the driving trip, and correlated appropriately with Fatigue Proneness, a driver stress trait. In the second study, 104 non-professional drivers completed identical subjective stress state measures as the professional drivers, before and after performing a driving trip. Drivers completed a measure of driving-related stress traits, the Driver Stress Inventory (DSI), and a measure of coping, the Driving Coping Questionnaire (DCQ). Both measures were predictive of state response to driving, and the association between Fatigue Proneness and post-drive fatigue found in the first study was replicated. Findings from these studies suggest that fatigue and stress reactions to driving are psychometrically distinct, but may have some common antecedents, such as use of emotion-focused coping. The studies confirm the importance of fatigue and stress as potential safety problems, but also highlight the role of individual differences in response to the demands of driving. 相似文献

A total of 779 article-embedded photographs from six popular US magazines during 2004 (Newsweek, Time, Fortune, Money, People, and Sports Illustrated) were examined assessing the relationship between occupational status and gender and the depiction of men and women in print
media. Results show individuals depicted in intellectually focused occupations had higher face-to-body ratios than individuals
depicted in physically focused occupations. Gender differences in facial prominence did not reach significance. A gender by
occupation interaction indicated men in intellectually focused occupations had higher face-to-body ratios than women in similar
professions, whereas women in physical occupations had higher face-to-body ratios than men in similar occupations. This suggests
a disparity in the media with regard to displaying men and women equally in similar occupational roles. 相似文献

The article considers the changing relationship between independent Pentecostal and charismatic groups and radical Islamic movements in Northern Nigeria between the 1970s and the early years of the twenty-first century. All these groups, be they Christian or Muslim, represent a new dimension in religious fundamentalism in contemporary Nigeria. In spite of being internal revivalist groups within their respective religious traditions, they reflect negative attitudes toward each other. Their relationship has been marked by continuous competition for public space. In the late 1980s and early 1990s, the demonization of Islamic groups was a feature of Pentecostal discourse. Through their involvement in political activities under the umbrella of the Christian Association of Nigeria (CAN), evangelicals and Pentecostals developed a common front in the face of Muslim fundamentalism. 相似文献

Among cancers, colorectal (CRC) is the third most incident and the second most lethal. Although screening for the disease has been shown to be effective in reducing morbidity and mortality, screening rates remain low. Risk of disease has been shown to increase screening uptake, but different types of risk may influence intent to screen, screening in a timely manner, or participating in screening at all. A cross-sectional design was used to select a diverse sample of CRC asymptomatic patients 50 or more years of age (N=104) visiting one of three Midwestern medical clinics. Results showed a positive relationship between receipt of CRC screening and planning to screen for CRC in the future. Objective risk factors (personal/family history and having a primary care physician) were associated with CRC screening uptake and screening within the time intervals recommended by professional screening guidelines, but subjective risk did not obtain significance for screening participation. Both objective (primary care physician) and subjective risk (long-term comparative risk, knowledge) were associated with future plans to screen. Findings suggest that CRC screening behaviors may be differentially influenced by type of risk. 相似文献

Millikan [2000] has levelled a number of persuasive criticisms against Cummins's [1996] theory of mental representation. In this paper, I pave a middle path in the debate between Cummins [2000] and Millikan [2000] to answer two questions. (1) How are representations applied to targets? (2) How is the content of a representation determined? The result is a new theory of mental representation, which I call narrow structuralism. 相似文献

Putnam and Searle famously argue against computational theories of mind on the skeptical ground that there is no fact of the matter as to what mathematical function a physical system is computing: both conclude (albeit for somewhat different reasons) that virtually any physical object computes every computable function, implements every program or automaton. There has been considerable discussion of Putnam's and Searle's arguments, though as yet there is little consensus as to what, if anything, is wrong with these arguments. In the present paper we show that an analogous line of reasoning can be raised against the numerical measurement (i.e., numerical representation) of physical magnitudes, and we argue that this result is a reductio ad absurdum of the challenge to computational skepticism. We then use this reductio to get clearer about both (i) what's wrong with Putnam's and Searle's arguments against computationalism, and (ii) what can be learned about both computational implementation and numerical measurement from the shortcomings of both sorts of skeptical argument. 相似文献

The ability of the early environment to programme the developing hypothalamo-pituitary-adrenal (HPA) axis has been reported in several animal species. There is considerable evidence that a similar process can occur in the human, and that long-term alterations in HPA function are associated with altered susceptibility to disease in later life. The phenotype of HPA function following early manipulation depends on the timing and intensity of the manipulation as well as the gender of the fetus/neonate. There is considerable interplay between the developing HPA and the reproductive axes and emerging evidence indicates that this interaction is modified by early environmental manipulation. Studies are rapidly unravelling the mechanisms that underlie developmental programming of the HPA axis. In this context, the serotonergic system has been identified as a primary system involved in this process. Understanding the mechanisms involved in neuroendocrine programming will facilitate the development of interventions aimed at reversing or ameliorating the impact of an adverse intrauterine environment. 相似文献
