该研究尝试用一种新的视角一取向研究视角,对以往情绪理论进行整合研究,建构一种与社会情境结合更紧密,更具概括性的情绪取向理论.情绪取向理论的假设建构模型包括四个维度:理性取向、感性取向、积极取向和消极取向.根据理论模型编制情绪取向量表,以779名被试为研究对象,运用探索性因素分析和验证性因素分析方法对该理论模型进行实证研究.结果证明了该理论建构的存在,理论建构中各维度的因素负荷和拟合指数良好,情绪取向量表具有良好的信度和建构效度.  相似文献

该研究以广州市与台中市大学生为被试,抽取500人为预测样本及800人为正式施测样本,通过探索性因素分析和验证性因素分析编制生命意义量表,并通过t检验和潜在剖面分析考察两岸大学生生命意义现况的差异.结果表明:(1)编制的生命意义量表由存在意义、追寻意义、存在盈实、苦难接纳、死亡接纳以及求意义的意志等6个维度组成,具有良好的信度和效度.(2)两岸大学生生命意义总体无显著差异;存在盈实、苦难接受与死亡接纳维度有显著或非常显著的差异.(3)潜在剖面分析结果显示,两岸大学生生命意义类型相似.Wald检验结果表明,对于“死亡接纳”维度,台湾与大陆学生在各潜在类别的均分上存在显著的差异.  相似文献

本文在对当前国内外主要心理统计学教材进行比较的基础上,指出与上个世纪八十年代的心理统计学教材内容相比较,在内容上的新探索主要体现在(1)由“假设检验”的内容中发展出“统计检验力”和“效果大小”的统计指标和估计方法;(2)引进一般线性模型来统合方差分析和回归分析这两种统计方法;(3)适度增加一些“多元统计分析”的内容等三个方面.本文对前两个方面的新内容作了简要评述,并对教材内容的编排方面提出了新的思路.  相似文献

主观幸福感回溯式自陈报告测量存在一定的不足,在此基础上研究者们发展了关注时间因素的即时测量方法,如经验取样法(ESM),生态瞬时评定法(EMA),日重现法(DRM),U指数(The U-Index)等.从传统测量走向多样化测量大大提高了主观幸福感测量的生态效度,同时也为国民幸福指数的构建与评估提供了一定参考.  相似文献

谊研宛采用工作压力源量表、压力反应量表以及积极心理资本问卷对天津市某企业230名员工进行了调查。分析了心理资本与工作压力源和压力反应的关系及其作用机制。结果发现:(1)工作压力源对压力反应有显著的正向预洲作用;(2)心理资本对压力反应有显著的负向预测作用;(3)心理资本在工作压力源与压力反应之间起部分中介作用而不是调节作用,其中中介效应占总效应的比例为16%;(4)心理资本在各种工作压力源与压力反应问均起到中介作用,中介效应和直接效应的比值介于17.4%-26.1%之间。  相似文献

Although many forms of differential treatment based on group membership are perceived to be legitimate, disadvantaged group members’ responses to discrimination have been studied primarily in contexts in which such treatment is appraised as illegitimate. This has resulted in an impoverished understanding of differential group-based treatment and a failure to illuminate the processes by which discrimination can shift from being seen as legitimate to being viewed as illegitimate. We discuss the determinants of disadvantaged group members’ legitimacy appraisals and the de-legitimisation process, whereby forms of discrimination appraised as legitimate come to be increasingly perceived as illegitimate. Whether group-based exclusion is addressed collectively or individually depends on socio-structural factors such as the pervasiveness of discrimination, impermeability of intergroup boundaries, and the availability of cognitive alternatives to the status quo. We conclude that understanding the antecedents and consequences of legitimacy appraisals is necessary to develop a comprehensive account of disadvantaged group members’ experiences of group-based discrimination.  相似文献

Exposure to a microgravity environment leads to adverse effects in motion and musculoskeletal properties. However, few studies have investigated the recovery of altered locomotion and muscle atrophy simultaneously. The authors investigated altered locomotion in rats submitted to simulated microgravity by hindlimb unloading for 2 weeks. Motion deficits were characterized by hyperextension of the knees and ankle joints and forward-shifted limb motion. Furthermore, these locomotor deficits did not revert to their original form after a 2-week recovery period, although muscle atrophy in the hindlimbs had recovered, implying discordance in recovery between altered locomotion and muscle atrophy, and that other factors such as neural drives might control behavioral adaptations to microgravity.  相似文献

Abstract

This 1-year longitudinal study examined the bidirectional mediating role of loneliness in the association between shyness and generalized pathological Internet use (GPIU) in a sample of 291 Chinese university students (143 men, mean age =?19.07?years). A fully cross-lagged panel design was used in which shyness, loneliness, and GPIU were assessed at 3 time points separated by 6-month intervals (named T1, T2, and T3). The results indicated that relationships among shyness, loneliness, and GPIU were dynamic and bidirectional. Specifically, T1 shyness positively predicted increased T2 loneliness, T2 shyness positively predicted increased T3 loneliness, and T2 loneliness positively predicted increased T3 shyness. Additionally, T1 GPIU positively predicted increased T2 loneliness, T2 GPIU positively predicted increased T3 loneliness, and T2 loneliness positively predicted increased T3 GPIU. Loneliness was found to play a bidirectional mediating role in the association between shyness and GPIU. Specifically, T1 shyness and T3 GPIU were mediated through increased loneliness at T2, and T1 GPIU and T3 shyness were mediated through increased loneliness at T2. Furthermore, relationships among shyness, loneliness, and GPIU were the same across the 2 groups, with the strength of relationships being stronger for men.  相似文献

The purpose of this study was to investigate the differences of knee concentric and eccentric strength and impact related knee biomechanics between jumpers and non-jumpers during step-off landing tasks. Ten male college swimming athletes (non-jumpers) and 10 track and volleyball athletes (jumpers) were recruited to participate in two test sessions: a muscle strength testing session of concentric and eccentric extension for dominant knee joint at 60 °/s and 180 °/s and a landing testing session. The participants performed five trials of step-off landing in each of four conditions: soft and stiff landing from 0.4 m and 0.6 m landing heights. The three-dimensional kinematics and ground reaction force were recorded simultaneously during step-off landing conditions. The results showed that the jumpers had significantly greater peak knee eccentric extension and concentric flexion torques compared to the non-jumpers. No significant group effects were found for peak vertical ground reaction force and knee range of motion during landing. The jumpers had significantly greater knee contact flexion angle, maximum knee flexion angle and initial knee extension moment compared to the non-jumpers. These results suggest that these athletes adopted a favorable impact attenuation strategy that is related to the greater knee eccentric muscle strength and training.  相似文献
