·12汶川地震发生两个月后,对508名灾区的幼儿园、中小学教师进行测量,结合他们对地震前状况的回忆,考察其地震后主观幸福感的变化情况及其影响因素。结果表明:(1)与回忆得到的地震前感受相比,地震后灾区教师体验到主观幸福感水平显著降低。(2)极重灾区教师体验到的主观幸福感降低程度大于重灾区和轻灾区教师。(3)教师遭受的客观损失严重程度能显著预测其体验到的主观幸福感降低;而创伤后身心症状在其中起完全中介的作用,即创伤事件引发教师创伤后身心症状,而这些症状日趋严重,使其体验到的消极情感增加、主观幸福感降低。  相似文献

Uncontrollability has been often associated with impaired or rigid cognitive processing. However, perceived stability of uncontrollable events modulated some of these detrimental effects on cognition. We investigated whether the experience of sequential control loss and restoration can enhance cognitive flexibility. We manipulated uncontrollability using a concept formation procedure that entailed either only unsolvable tasks (control deprivation condition), unsolvable tasks followed by solvable ones (control restoration condition) or only solvable tasks (control condition). To assess cognitive flexibility, we used a task-switching procedure that incorporated social categories. In Experiment 1 participants categorized people based on gender or age, and in Experiment 2 and 3 based on gender or social roles. Participants showed more flexibility in control restoration than in control deprivation condition. Additionally, in Experiments 2 and 3 this effect was mainly pronounced in the condition where the task evoked more cognitive conflict. We discuss the motivational underpinnings of unstable experiences of control loss and restoration.

African American adolescent girls are at increased risk of being exposed to community violence and being diagnosed with a sexually transmitted infection. Fewer studies, however, have examined the protective roles of natural mentorship and organizational religious involvement as potential moderators that could lessen the effects of violence exposure on health risk behavior. Data from 273 African American ninth grade girls were used to test hypothesized independent and moderated‐moderation models. Results suggest that natural mentorship and religious involvement were protective for girls who reported at least one mentor and moderate to high levels of religious involvement. Our findings may be relevant for community stakeholders and organizations that directly interact with religious institutions and community programs that focus on outreach to African American adolescent girls.  相似文献

This paper reports the results of our study that assessed the treatment efficacy of multiple family therapy (MFT) from the perspective of participating Chinese children with attention deficit hyperactivity disorder (ADHD) and identified their subjective experiences. Forty‐three children with ADHD in the experimental group (EG) completed a forty‐two‐hour MFT, whilst forty‐five children with ADHD in the control group (CG) had attended two writing classes scheduled three months apart that were similar to those of the MFT. Data from the outcome study were gathered using standardized questionnaires and data from the qualitative study were drawn from thirteen children with ADHD who had completed the MFT and attended the focus group interviews (n = 5) or individual interviews (n = 8) conducted in the post‐treatment phase. The results of the Paired sample t‐test and MANOVA indicated no significant changes on the scores for the four measures adopted (perception of competence, hopefulness, parent‐child relationship and perceived social support) in the pre‐ and post‐treatment for the EG and the CG. Five themes emerged from the narratives of children with ADHD, which revealed the children’s subjective experiences with the MFT: (a) full of fun; (b) building friendships through common experiences; (c) a happy family time; (d) safe space; and (e) positive parental responses and communications.  相似文献

基于分部评分模型的思路, 本文提出了一般化的分部评分认知诊断模型(General Partial Credit Diagnostic Model, GPCDM), 与国际上已有的基于分部评分模型思路的多级评分模型GDM (von Davier, 2008)和PC-DINA (de la Torre, 2012)相比, GPCDM的Q矩阵定义更加灵活, 项目参数的约束条件更少。Monte Carlo实验研究表明, GPCDM模型的参数估计精度指标RMSE介于[0.015, 0.043], 表明估计精度尚可; TIMSS (2007)实证数据应用研究表明, 与GDM和PC-DINA模型相比, GPCDM与该数据的拟合度更好, 并且使用GPCDM分析该数据的诊断效果也更优。总之, 本研究提供了一种约束条件更少、功能更为强大的多级评分认知诊断模型。  相似文献

从契约制定过程角度,探究个体制定契约参与度对人际信任的影响及其机制。现场研究结果表明参与制定宿舍契约能提升宿舍人际信任,认同感在其中起中介作用。实验室实验结果表明:契约参与度不但能提升被试对其他被试的情感(善心)和认知(依赖)信任,而且能提升被试在信任游戏中对其他被试的信任行为; 并且认同感在前者的关系中起中介作用。综合两个研究结果,契约参与度能提高对共同参与制定契约的同伴的信任,且社会认同能解释这种影响。  相似文献

To differentiate romantic disillusionment from similar constructs of dissatisfaction and regret, functional Magnetic Resonance Imaging (fMRI) data obtained when romantically involved individuals (N = 39) were reminded of relationship events representing these emotions were analyzed. Whole‐brain activations suggested disillusionment‐linked processes not observed for dissatisfaction or regret. Compared to dissatisfying events, disillusioning ones showed greater activity in regions pertaining to evaluation, reflection, and reconciling conflicting information (e.g., anterior cingulate cortex). No regions showed significantly more activation for dissatisfying than disillusioning events. Compared to regret‐inducing events, disillusioning events showed greater activation in areas thought pertinent to detail processing and decision making (occipital fusiform and lingual gyrus). Regret‐inducing events activated regions suggesting the planning and thoughts of how one could have acted differently (e.g., prefrontal cortex).  相似文献

不同社会群体特征对内隐领导因素的影响   总被引:2,自引:0,他引:2  
研究发现,中国人内隐领导理论的内容由个人品德、目标有效性、人际能力和多面性四个因素构成。不同的年龄、职业和教育水平等评分者的特点,对领导诸因素的评分有着显著的影响。综合分析发现,教育水平是影响内隐领导因素评分的主要变量。另外,各组都倾向于把人际能力作为领导最大的特质来加以评分。  相似文献
