The mental and physical health of 146 Dutch males exposed to severe war stress during their young adulthood were examined in 1986-1987 when they were at ages 61 to 66 years. The veterans' data were compared with a randomly selected population-based sample of same-aged males. In 2005, 70% of the war stress veterans had died, and only 35% of the comparison group. The baseline quality of life was significantly poorer in the war stress veterans than in the comparison group. Baseline variables explained 42% of the increased risk of mortality among war stress veterans. Smoking was the largest single contributor to mortality. 相似文献

Prior research has shown that depressive symptoms are associated with an enhanced attention toward negative stimuli and difficulty of disengaging attention from negative stimuli. The current study was an extension of a 2005 study by Koster and colleagues. A different stimulus presentation time and word set were used. The whole range of depressive symptoms was included in this sample instead of creating dichotomized groups. The Exogenous Cueing Task with negative, positive, and neutral cues was administered to 85 female undergraduate university students. Participants completed the Beck's Depression Inventory-II-NL questionnaire to measure self-reported depression. Contrary to previous findings, depressive symptoms were related to a facilitated rather than impaired attentional disengagement from negative stimuli. An explanation for the discrepancy with findings from Koster, et al. may be the different stimulus presentation time (1000 msec. instead of 500 or 1500 msec.). 相似文献

Two word fluency tasks, the FAS letter fluency task and the "animal" semantic fluency task, were administered to 130 healthy Swedish-speaking children between 6 and 15 years of age. The main aim was to gather normative data on these word fluency tasks for Swedish-speaking children. Another purpose was to examine the switching and clustering strategies used, along with the occurrence of erroneous responses, in relation to demographic data and number of words retrieved. Both phonological and semantic analyses of switching and clustering were conducted. Higher age was found to be related to a more effective use of phonological and semantic switching and clustering strategies. The reference data resulting from this study may be of clinical value in examinations of children with various diagnoses, including language impairment. 相似文献

Authoritarianism is a stable construct in terms of individual differences (social attitudes based on personality and values), but its manifestations and behavioral outcomes may depend on contextual factors. In the present experiment, we investigated whether authoritarianism is sensitive to religious influences in predicting rigid morality. Specifically, we investigated whether authoritarians, after supraliminal religious priming, would show, in hypothetical moral dilemmas, preference for impersonal societal norms even at the detriment of interpersonal, care‐based prosociality toward proximal persons and acquaintances in need. The results confirmed the expectations, with a small effect size for the religious priming × authoritarianism interaction. In addition, these results were specific to participants' authoritarianism and not to their individual religiosity. The interaction between authoritarian dispositions and religious ideas may constitute a powerful combination leading to behaviors that are detrimental for the well‐being and the life of others, even proximal people, in the name of abstract deontology.

The present research demonstrates that the attention bias to angry faces is modulated by how people categorize these faces. Since facial expressions contain psychologically meaningful information for social categorizations (i.e., gender, personality) but not for non-social categorizations (i.e., eye-color), angry facial expression should especially capture attention during social categorization tasks. Indeed, in three studies, participants were slower to name the gender of angry compared to happy or neutral faces, but not their color (blue or green; Study 1) or eye-color (blue or brown; Study 2). Furthermore, when different eye-colors were linked to a personality trait (introversion, extraversion) versus sensitivity to light frequencies (high, low), angry faces only slowed down categorizations when eye-color was indicative of a social characteristic (Study 3). Thus, vigilance for angry facial expressions is contingent on people's categorization goals, supporting the perspective that even basic attentional processes are moderated by social influences. 相似文献

The authors test predictions from climato-economic theories of culture that climate and wealth interact in their influence on psychological processes. Demanding climates (defined as colder than temperate and hotter than temperate climates) create potential threats for humans. If these demands can be met by available economic resources, individuals experience challenging opportunities for self-expression and personal growth and consequently will report lowest levels of ill-being. If threatening climatic demands cannot be met by resources, resulting levels of reported ill-being will be highest. These predictions are confirmed in nation-level means of health complaints, burnout, anxiety, and depression across 58 societies. Climate, wealth, and their interaction together account for 35% of the variation in overall subjective ill-being, even when controlling for known predictors of subjective well-being. Further investigations of the process suggest that cultural individualism does not mediate these effects, but subjective well-being may function as a mediator of the impact of ecological variables on ill-being. 相似文献

The aim of the study was to train and test support vector machines (SVM) and self-organizing maps (SOM) to correctly classify gait patterns before, during and after complete leg exhaustion by isokinetic leg exercises. Ground reaction forces were derived for 18 gait cycles on 9 adult participants. Immediately before the trials 7–12, participants were required to completely exhaust their calves with the aid of additional weights (44.4 ± 8.8 kg). Data were analyzed using: (a) the time courses directly and (b) only the deviations from each individual’s calculated average gait pattern. On an inter-individual level the person recognition of the gait patterns was 100% realizable. Fatigue recognition was also highly probable at 98.1%. Additionally, applied SOMs allowed an alternative visualization of the development of fatigue in the gait patterns over the progressive fatiguing exercise regimen. 相似文献

Several studies have shown that the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992) is diminished for highly arousing T2 stimuli (e.g., Anderson, 2005). Whereas this effect is most often interpreted as evidence for a more efficient processing of arousing information, it could be due also to a bias to report more arousing stimuli than neutral stimuli. We introduce a paradigm that allows one to control for such a response bias. Using this paradigm, we obtained evidence that the diminished AB for taboo words cannot be explained by a response bias. This supports the idea that the emotional modulation of the AB is caused by attentional processes. 相似文献
