Previous studies consistently found that trait self-compassion is positively associated with health-promoting behaviours, and perceived stress mediates the relationship. The current study primarily aimed at examining whether state self-compassion varying from day to day (daily self-compassion) played the same role as trait self-compassion in improving health-promoting behaviours and whether or not perceived stress would be the mediator in this relationship. Eighty-nine Chinese employees were recruited to finish demographic information and the trait measure of self-compassion first, and then finish daily diaries for seven consecutive days. Daily diary measures included daily self-compassion, perceived stress and health-promoting behaviours including both eating behaviours and exercise behaviours. The results of 1-1-1 multilevel mediation analyses showed that, at both the within- and between-person level, daily self-compassion could positively predict daily eating behaviour through the reduction of perceived stress. However, daily self-compassion did not influence exercise behaviour at both levels. The results of 2-1-1 multilevel mediation analyses cross-validated the between-person relationships in the 1-1-1 multilevel mediation models. These results suggest that, both short-term interventions aiming at increasing state self-compassion and long-term interventions aiming at increasing trait self-compassion can benefit one's eating behaviours through the reduction of stress. 相似文献

The authors examined the relative contribution of ethnicity, life satisfaction, level of stress, familiarity with mental health treatment, and self- and public stigma on attitudes toward mental health treatment among a diverse sample (N = 632) of adults. Results indicated that ethnicity, stress, familiarity, and self-stigma of mental illness were significant predictors of attitudes. Additionally, familiarity with mental health treatment moderated the relationship between public stigma and attitude. 相似文献

While the operational and crash reduction benefits of adaptive signal control technology (ASCT) have long been investigated, the impact of this technology on driver behavior and stress is still uncertain. This study evaluated the impact of ASCT on driver behavior and stress in a real-world environment. Participants travelled through two arterial corridors, one equipped with ASCT and the other having traditional time-of-day coordinated signals. Driver stress was measured using a heart rate detector and a perceived stress scale while driver behavior was examined using vehicular trajectory data. Overall, driving behavior improved on the ASCT as compared to the non-ASCT corridor, as indicated by higher speeds and a fewer number of stops on the ASCT corridor relative to the non-ASCT corridor. Repeated measures ANOVA showed a statistically significant reduction in driver heart rate by −10 beats per minute over the ASCT corridor. A similar trend was observed for drivers’ perceived stress, analyzed by Wilcoxon sign ranked test. Driving behavior also showed significant improvement with ASCT presence, and speed was found to be negatively correlated with stress. Furthermore, the participants’ speed was controlled by the two systems i.e. ASCT and non-ASCT as expected. This study provides a significant proof of concept that ASCT can create positive improvements in driver stress and behavior that can be further investigated in the future. 相似文献

Although much is known about working memory (WM) and emotion perception deficits in schizophrenia, little is known of how these deficits interact. We sought to address this gap by conducting a narrative review of relevant literatures and distilling core themes. First, people with schizophrenia have difficulty with high load and during initial phases of WM (e.g., encoding, early rehearsal), yet are able to activate WM-related prefrontal brain regions to the same maximal degree as comparison controls under certain circumstances. Second, people with schizophrenia have difficulty identifying and expressing facial emotions, yet demonstrate heightened automatic/implicit processing of facial emotions. Third, people with schizophrenia behaviourally demonstrate intact cognition–emotion interactions on laboratory tasks wherein emotional processing is automatic/implicit, yet demonstrate cognition–emotion disconnections in other levels of analysis. Insights are drawn from basic science showing interdependency between WM load and implicit emotion. Future research questions are raised regarding interactions between WM load and implicit facial-affective processing in schizophrenia. 相似文献

回顾了近20年来军事应激下的有关认知工效学研究,主要包括五部分:基本理论;应激对认知的影响;研究方法;处理应激的方法;总结。其中在研究方法中重点是对已有事故的分析,竞争性游戏和虚拟现实技术。在减少应激对认知不良影响的方法中值得注意的是:对抗应激人员的选拔、对人员的训练和能够对抗应激的人-机系统的开发。对于我军今后类似研究提供了思路和可能入手点 相似文献

急性情绪应激对大鼠行为和脑神经颗粒素磷酸化水平的影响 总被引:2,自引:1,他引:1
为探讨急性情绪应激对大鼠旷场行为的影响,以及脑神经颗粒素(Neuroganin,NG)变化与应激性行为效应之间的相互关系。以急性不确定性空瓶刺激,建立情绪应激动物模型。将40只雄性SD大鼠随机分为情绪应激组1(ES1,接受情绪应激和旷场测试)、情绪应激组2(ES2,只接受情绪应激)、正常对照组1(C1,无情绪应激,但接受旷场测试)和正常对照组(C2,无情绪应激,也无旷场测试)(n=10)。以旷场行为和高架十字迷宫任务来评定大鼠应激后的行为变化,Western印迹杂交法(Western blotting)测定海马和前脑皮层中的NG含量和磷酸化水平。结果表明:(1) 应激后ES1组的水平活动增加,与C1组比较,差异有显著性, p<0.01;(2)ES1组海马和前脑皮层的NG磷酸化水平高于C1和C2组,差异有显著性, 均为p<0.05; ES2组的前脑皮层NG的磷酸化水平高于C1组,差异有显著性,为p<0.05;(3) 海马的NG磷酸化水平与水平活动之间的相关达显著水平。提示急性情绪应激能导致动物明显的行为改变如焦虑,这种行为改变可能与脑内NG磷酸化水平的变化有关。水平活动可能是反映急性情绪应激的较敏感行为指标,海马NG磷酸化水平可能是预测急性情绪应激所致焦虑或抑郁行为的较敏感生物学指标 相似文献

不同应激范式对大鼠行为和脑神经颗粒素含量的影响 总被引:4,自引:2,他引:2
为探讨慢性情绪应激、生理应激对大鼠旷场行为和脑神经颗粒素(Neurogranin,NG)含量的不同作用,以及NG含量变化与应激性行为效应之间的相互关系。分别以不确定性空瓶刺激和饮水剥夺,建立情绪应激和生理应激动物模型。将40只雄性SD大鼠随机分为情绪应激组(ES)、生理应激组(PS)、定时饮水组(C1)和正常对照组(C2)(n=10)。以旷场行为任务来评定大鼠应激后的行为变化,Western blotting方法测定海马和前脑皮层中的NG含量。结果表明:应激后四组大鼠海马的NG含量差异无显著性;ES组前脑皮层的NG含量低于C2组,差异具有显著性,p<0.01;PS组的前脑皮层NG含量也下降,但与C2组相比差异无显著性; 应激后ES组、PS组修饰行为多于C2组,差异具有显著性,分别为p<0.01,p<0.05;前脑皮层NG含量与修饰行为之间的相关达显著水平。提示慢性情绪和生理应激均能导致前脑皮层NG含量下降,修饰行为增加,情绪应激作用更显著。修饰行为可能是反映情绪状态的较敏感行为指标,前脑皮层NG水平可能是预测情绪应激所致焦虑或抑郁行为的较敏感生物学指标。 相似文献

The aim was to explore the patterns of correlations between psychosocial stress indices and neuroendocrinological factors
in managers. Fifty-eight male managers in three Swedish companies constituted the sample. They answered two questionnaires
with 17 selected stress indices and also an organizational test. The indices have been analyzed by means of computations of
age adjusted partial correlations with nine different variables analyzed in fasting blood samples. The serum concentrations
of lipids were the variables most strongly correlated with psychosocial factors. Neither smoking nor physical activity changed
the correlations significantly. Good social support at work and in private life was consistently associated with low adverse
serum lipids and corresponding lipoproteins. On the other hand, some indices of social support were associated with indices
of high arousal levels. This may indicate a possible psychophysiological “load effect” of some aspects of social support in
managers. The analyses of corporate culture measured as “Rules of the Game” indicated that “bureaucracy” was significantly
associated with high LDL-cholesterol and low HDL-cholesterol. Managers have special conditions and therefore the patterns
of associations between psychosocial conditions and coping strategies on one hand and endocrine-biochemical state on the other
hand may be different, from those of other groups. To what extent such differences are due to individual characteristics or
environmental factors needs to be further investigated. According to the results, however, good social support is in general
health promoting also to managers, at least with regard to serum lipids. Bureaucracy, on the other hand, seems to be dangerous
to the health of managers. 相似文献

The Chronic Mild Stress (CMS) model for depression has become central to the empirical literature on depression. There are
however inconsistencies in the literature concerning the robustness of the phenomenon of anhedonia following CMS procedures.
We report that not only did our procedures (modeled on the original reports) fail to induce an anhedonia, but in fact led
to increased sucrose consumption. Furthermore, corticosterone levels following CMS procedures were lower than following control
procedures. Given that this is not the first report of such findings, it is important to evaluate whether and which aspects
of the experimental methodology are necessary or sufficient to induce the state of anhedonia. 相似文献
