Chronic stress weakens the immune system and leads to heightened bodily inflammation, which in turn is linked with serious health conditions. This study examined whether religiosity moderates the relationship between stress and inflammation (measured by C-reactive Protein (CRP)). A sample of 4,734 community-dwelling older adults was drawn from the 2006 wave of the Health and Retirement Study. Logistic regression was used to analyze the relationship between chronic stress (8-item index), inflammation (high CRP level), and religiosity (organizational, nonorganizational, and intrinsic), controlling for other factors. Higher levels of stress were significantly associated with high inflammation/CRP (p = .039). Further, intrinsic religiosity acted as a moderator of this relationship (p = .024), such that the relationship between stress and inflammation is lessened for persons with higher levels of intrinsic religiosity. Higher intrinsic religiosity attenuated the effects of stress on inflammation, suggesting that individuals with stronger religious commitment/motivation may better cope with stress. 相似文献

Predictors of Cheating Behavior at a University: A Lesson From the Psychology of Work 总被引:1,自引:0,他引:1

The present study investigated students' behavior across academic departments to establish how personality, demographic, educational, attitudinal, and climate (both psychological and departmental) predicted self-reported cheating behavior at a university. Participants were 107 students from a variety of academic disciplines. The results explain 50.5% of the variability in self-reported cheating behavior in terms of demographic (male, school education qualifications), departmental climate, and individual differences (Lie and Neuroticism scales). We concluded that an expanded theoretical perspective (utilizing a wide range of person and situation variables) explained more variability than would otherwise be explained from any single perspective, and that findings from the literature of integrity at work generalize to educational settings. Finally, we discuss the limitations and implications of this research. 相似文献

The beliefs that individuals hold about knowledge and knowing have been the focus of a growing body of work on “personal epistemology.” There has been general agreement among researchers about a developmental trajectory of epistemological understanding that takes place in adolescence and adulthood. Rarely has this research included children, however, and we know little about the origins of epistemological awareness or its early development. A separate group of researchers have investigated children's “theory of mind,” or the ability to understand others’ beliefs, actions, and desires, with primary attention to the onset of this cognitive achievement between the ages of 3 and 5. This article reviews the theoretical foundation for a proposed relation between these constructs, and reports on an exploratory investigation with 3–5 year olds, in which epistemological level was significantly related to theory of mind ability. Results are discussed in relation to a general timeline depicting the development of children's beliefs about knowledge and knowing, a process that involves an ongoing tension between objective and subjective perspectives. We propose that the trajectory of epistemological development be expanded to include an initial period of egocentric subjectivity that characterizes epistemological thinking prior to the achievement of theory of mind. 相似文献

This paper briefly examines ethics as a process and as an element of philosophy with a long historical tradition. The paper then reviews elements of the professional ethics of a terrorist or hostage event, issues involved with consulting with an institution, and ethical issues for the clinician who chooses to become personally involved in a hostage event. Although reference is made particularly to psychiatrists, the principles discussed apply in large part to other mental health professionals as well. The paper concludes with the principles articulated by the American Psychiatric Association's Task Force on the Psychiatric Aspects of Terrorism and Its Victims as guidelines for psychiatric intervention in hostage or terrorist situations. 相似文献

Recognition of positive and negative bandpass-filtered images 总被引:4,自引:0,他引:4
A study is reported in which the significance for vision of low- and high-spatial-frequency components of photographic positive and negative images was investigated by measuring recognition of bandpass-filtered photographs of faces. The results show that a 1.5 octave bandpass-filtered image contains sufficient visual information for good recognition performance, provided the filter is centred close to 20 cycles facewidth-1. At low spatial frequencies negatives are more difficult to recognize than positives, but at high spatial frequencies there is no difference in recognition, implying that it is the low-frequency components of negatives which present difficulties for the visual system. 相似文献

Prolonged adaptation to delayed sensory feedback to a simple motor act (such as pressing a key) causes recalibration of sensory‐motor synchronization, so instantaneous feedback appears to precede the motor act that caused it (Stetson, Cui, Montague & Eagleman, 2006). We investigated whether similar recalibration occurs in school‐age children. Although plasticity may be expected to be even greater in children than in adults, we found no evidence of recalibration in children aged 8–11 years. Subjects adapted to delayed feedback for 100 trials, intermittently pressing a key that caused a tone to sound after a 200 ms delay. During the test phase, subjects responded to a visual cue by pressing a key, which triggered a tone to be played at variable intervals before or after the keypress. Subjects judged whether the tone preceded or followed the keypress, yielding psychometric functions estimating the delay when they perceived the tone to be synchronous with the action. The psychometric functions also gave an estimate of the precision of the temporal order judgment. In agreement with previous studies, adaptation caused a shift in perceived synchrony in adults, so the keypress appeared to trail behind the auditory feedback, implying sensory‐motor recalibration. However, school children of 8 to 11 years showed no measureable adaptation of perceived simultaneity, even after adaptation with 500 ms lags. Importantly, precision in the simultaneity task also improved with age, and this developmental trend correlated strongly with the magnitude of recalibration. This suggests that lack of recalibration of sensory‐motor simultaneity after adaptation in school‐age children is related to their poor precision in temporal order judgments. To test this idea we measured recalibration in adult subjects with auditory noise added to the stimuli (which hampered temporal precision). Under these conditions, recalibration was greatly reduced, with the magnitude of recalibration strongly correlating with temporal precision. 相似文献

This study explored whether factors related to the work environment could predict changes in body mass index (BMI) and whether the effect of psychosocial factors was dependent on baseline BMI. The sample consisted of 1,980 male employees from the Danish National Work Environment Cohort Study. Changes in BMI between 1995 and 2000 were analyzed, by multiple regression, as a function of background variables and a series of occupational variables obtained in 1995. Age, baseline BMI, job insecurity, and psychological demands predicted changes in BMI. Job insecurity and high or low psychological demands increased the likelihood of weight gain among obese employees, whereas they increased the likelihood of weight loss among employees with a low BMI. 相似文献

Human performance on instances of computationally intractable optimization problems, such as the travelling salesperson problem (TSP), can be excellent. We have proposed a boundary-following heuristic to account for this finding. We report three experiments with TSPs where the capacity to employ this heuristic was varied. In Experiment 1, participants free to use the heuristic produced solutions significantly closer to optimal than did those prevented from doing so. Experiments 2 and 3 together replicated this finding in larger problems and demonstrated that a potential confound had no effect. In all three experiments, performance was closely matched by a boundary-following model. The results implicate global rather than purely local processes. Humans may have access to simple, perceptually based, heuristics that are suited to some combinatorial optimization tasks. 相似文献
