Co-rumination and Immune Inflammatory Response in Healthy Young Adults: Associations with Interleukin-6 and C-Reactive Protein     

Justin P. Boren  Alice E. Veksler 《Communication Research Reports》2018,35(2):152-161

A rich literature exists reinforcing the notion that both perceived and received social support has stress ameliorating and protective benefits both psychologically and physiologically. However, recent literature suggests that excessive dyadic negative problem talk about an issue, a phenomenon labeled co-rumination, may reverse much of the beneficial effects of social support. Healthy young adults participated in a laboratory research study exploring the associations between co-rumination and immune system inflammatory response. Partial correlations indicated a positive association between co-rumination and C-reactive protein and a negative association between co-rumination and interleukin-6 after controlling for stress, anxiety, and temperature. Discussion focuses on the means by which co-rumination may lead to negative health outcomes.  相似文献

竞技运动中自我控制的反语效应     

郑猛  张雯 《福建体育科技》2010,29(4):32-34,43

自我控制的反语效应是指处于高心理压力下的个体,努力想控制自己的心理状态,由于消极暗示（他人给予的或自我给予的）的原因,往往得到与期望相反结果的现象。本文的目的是考察关于运动技术表现失败的自我控制的反语效应。研究中,方便抽样抽取63名被试,随机分配到低压力和高压力情景中的积极暗示组、消极暗示组和控制组。结果发现,高压力下,消极暗示组更容易使被试产生自我控制的反语效应。研究结果提示：较大的比赛压力下,教练员不应对运动员消极暗示,而应是积极暗示,这样可能会有效地避免反语效应的发生。  相似文献

Prediction of stress levels in the workplace using surrounding stress     

《Information processing & management》2022,59(6):103064

Occupational stress has a significant adverse effect on workers’ well-being, productivity, and performance and is becoming a major concern for both individual companies and the overall economy. To reduce negative consequences, early detection of stress is a key factor. In response several stress prediction methods have been proposed, whose primary aim is to analyse physiological and behavioural data. However, evidence suggests that solutions based on physiological and behavioural data alone might be challenging when implemented in real-world settings. These solutions are sensitive to data problems arising from losses in signal quality or alterations in body responses, which are common in everyday activities. The contagious nature of stress and its sensitivity to the surroundings can be used to improve these methods. In this study, we sought to investigate automatic stress prediction using both surrounding stress data, which we define as close colleagues’ stress levels and the stress level history of the individuals. We introduce a real-life, unconstrained study conducted with 30 workers monitored over 8 weeks. Furthermore, we propose a method to investigate the effect of stress levels of close colleagues on the prediction of an individual’s stress levels. Our method is also validated on an external, independent dataset. Our results show that surrounding stress can be used to improve stress prediction in the workplace, where we achieve 80% of F-score in predicting individuals’ stress levels from the surrounding stress data in a multiclass stress classification.  相似文献   

运动训练适应理论研究综述--兼论运动训练的本质     

张建华 《四川体育科学》2014,(4):63-67

采用文献资料法和逻辑分析法,借助生物适应理论探讨运动训练的本质,为提高运动员竞技能力提供理论依据。运动训练是有目的的改造人类自身的实践活动,其本质就是基于内稳态的生物适应,是对内稳态理论的应用与发展。运动训练中人体对训练负荷产生的应激反应,能引起有机体机能水平的适应性提高,适应过程和适应机理均可通过应激学说来解释。训练刺激会给机体内部带来正负两种效应：适应效应和疲劳效应。在有效的时间内,任何一次训练刺激最终表现为正负两种效应的综合。  相似文献
