再探框架对风险决策行为的影响

期望理论运用Ｓ状的价值函数和非线性的权重函数来解释和预测框架效应。“齐当别”抉择模型将不同框架下的抉择行为简单地看成是“最好可能结果之间的取舍”或者“最坏可能结果之间的取舍”。本研究设计了一“匹配”技术,并用此对作者所报告过的支持框架效应与不支持框架效应的选择问题加以再检验。实验表明,采用不同的框架并不能预测性地决定不同的抉择偏爱,而匹配结果所示的“齐当别”策略则能更好地对所收集到的有关框架效应的数据作出解释。     

5·12汶川地震后灾区教师主观幸福感的变化趋势及中介效应分析

·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。

Violence Exposure and Sexual Risk Behaviors for African American Adolescent Girls: The Protective Role of Natural Mentorship and Organizational Religious Involvement

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.     

基于分部评分模型思路的多级评分认知诊断模型开发

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。     

Functional magnetic resonance imaging activation in response to prompts of romantically disillusioning events

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).     

不同社会群体特征对内隐领导因素的影响

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。     

社会称许性反应的测量与控制

社会称许性反应是影响人格测验效度最常见的一种反应偏差,从20世纪30年代至今,测量学家一直努力揭示社会称许性反应的性质和内部结构,并开发社会称许性量表对其直接测量。本文综述了社会称许性量表的发展脉络,指出了至今遗留的问题。并且,从事前控制和事后控制的角度,对当前主要的控制社会称许性反应的方法进行了论述,指出了社会称许性量表的效度对事后控制方法的重要影响,并给出了一些如何控制社会称许性反应的指导建议。

Physical interpersonal relationships and social anxiety among online game players.

Many online game players spend inordinate amounts of time in their favorite virtual worlds. A large percentage of these players are teenagers who show behaviors normally associated with physical addiction. Parents, educators, and social scientists are therefore saying that online games are sources of social problems. The authors surveyed 174 Taiwanese college-age online players to collect data on the potential effects of online games on the quality of interpersonal relationships and levels of social anxiety. According to the results, the quality of interpersonal relationships decreased and the amount of social anxiety increased as the amount of time spent playing online games increased.
