Effects of Three Sources of Social Support on Survivors' Posttraumatic Stress After the Wenchuan Earthquake

This study investigated the relationship between social support and symptoms of posttraumatic stress among adolescents who were exposed to the 2008 Wenchuan earthquake in China. The results showed that three sources of social support—support from family, support from friends, and support from significant others—have significant main effects on posttraumatic stress disorder (PTSD). Buffering effects of social support were not supported. Gender and residency were also associated with PTSD, with female adolescents and adolescents from rural areas demonstrating higher levels of PTSD than their male counterparts and adolescents from urban and township areas.     

Influence of Culture on Ethical Decision Making in Psychology

This study focused on the influence of American and Chinese cultures on consequentialism orientation in decision-making within the broader context of psychologists’ academic roles and responsibilities. In addition, this study hypothesized that educational level would affect culturally influenced ethical decision making in both cultures. Based on the American Psychological Association Ethics Code, 20 ethical scenarios in 5 domains in psychology were created and used to examine the influence of culturally ethical beliefs on psychologists’ decision making among 181 participants. The results indicated that significant cultural differences in consequentialism orientation differentiated Chinese and American participants and influenced their resolution of ethical issues.     

听觉诱发表象的眼动机制

视觉心理表象是一种基于过去经验的自上而下的加工过程,它是信息表征的一种形式.以往的研究主要采用视觉来诱发表象,但是这很难排除视觉后像的干扰,而且与表象“自上而下”的加工过程不一致.听觉诱发表象很好地解决了视觉后像的干扰问题,也更吻合表象“自上而下”的加工过程,因为被试产生的表象是基于自己过去的经验,从自身出发,主动加工的结果.采用实验法,考察通过听觉通道诱发表象眼动的情况,使用眼动仪记录被试的眼动轨迹.结果发现：（1）不管是运动还是静止的物体,都能诱发表象,在表象时存在眼动行为.（2）运动的物体诱发眼动的程度更大.（3）眼动影响表象的建构,在表象建构中起机能性作用.     

A New Online Calibration Method for Multidimensional Computerized Adaptive Testing

Multidimensional-Method A (M-Method A) has been proposed as an efficient and effective online calibration method for multidimensional computerized adaptive testing (MCAT) (Chen & Xin, Paper presented at the 78th Meeting of the Psychometric Society, Arnhem, The Netherlands, 2013). However, a key assumption of M-Method A is that it treats person parameter estimates as their true values, thus this method might yield erroneous item calibration when person parameter estimates contain non-ignorable measurement errors. To improve the performance of M-Method A, this paper proposes a new MCAT online calibration method, namely, the full functional MLE-M-Method A (FFMLE-M-Method A). This new method combines the full functional MLE (Jones & Jin in Psychometrika 59:59–75, 1994; Stefanski & Carroll in Annals of Statistics 13:1335–1351, 1985) with the original M-Method A in an effort to correct for the estimation error of ability vector that might otherwise adversely affect the precision of item calibration. Two correction schemes are also proposed when implementing the new method. A simulation study was conducted to show that the new method generated more accurate item parameter estimation than the original M-Method A in almost all conditions.     

团队中帮助行为的多水平整合模型

团队中帮助行为包含团队成员个体帮助行为, 成员-成员的人际帮助, 以及团队帮助行为。既有研究聚焦于团队中个体帮助行为的积极作用, 忽视了施助者与受助者之间的二元关系影响、以团队为研究层级的帮助行为机理及团队中不同层级间的影响效应研究。研究提出团队中帮助行为的多水平整合理论模型框架, 认为未来研究应进一步探讨团队帮助行为的涌现溢出机制及团队中帮助行为可能存在的负面效应的内在心理机制。     

整体运动知觉老化伴随颞中回静息态功能改变

以个体整体运动一致性阈值为指标, 探讨老年人整体运动敏感性(GMS)下降和静息态下兴趣脑区功能活动的关系。发现与阈值负相关且老年人低于青年人的指标主要有：MT/V5区的ReHo和ALFF值, 各网络拓扑属性; 与阈值正相关且老年人显著高于青年人的有：MT/V5区与前运动皮层之间的、各兴趣脑区之间的功能连接。结果用“去分化”等观点进行了解释, 提示老年人GMS的下降可能不仅与安静状态下MT/V5区的功能改变有关, 还可能与全脑更广泛区域的功能改变有关。     

中国人整体性思维特征的情境评估法及其应用

创设了新的中国人思维特征的情境评估方法, 初步应用于整体性思维特征与创造力倾向关系的研究并对其信效度进行了检验。新评估法选取体现典型文化意境和中国人思维特征的成语谜语作为材料, 利用虚拟现实技术构建形与意、情境与语境相互转换的成语谜语文化园, 记录被试游览时即景说出的成语建立成语库, 并编码所录成语的思维特征类型以作为被试的整体性思维测量指标。基于测试数据的信效度分析表明整体性思维成语测试系统信效度表现良好。整体性思维与创造力倾向的相关分析表明, 整体性思维与创造力倾向中的好奇性显著负相关。研究首次证实了利用虚拟现实技术来重建传统文化情境以实现对中国人思维特征的情境评估的可行性, 提示基于虚拟现实技术的情境评估法在未来心理学相关研究中的应用价值。     

基于正念的干预与自我同情的关系：一项元分析

运用元分析方法对国内外有关基于正念的干预与自我同情的关系问题进行了探讨, 通过文献检索, 纳入文献65篇, 总样本量为8103。异质性检验发现, 选择随机效应模型比较合适; 敏感性分析显示, 使用One-study removed逐步删除异质性较高研究, 基于正念的干预与自我同情呈显著正相关; 次群体检验表明, 基于正念的干预与自我同情关系受对比方式的调节与影响, 但不受群体和测量工具的影响。研究结果表明, 正念对自我同情水平会产生不同程度的积极影响, 同时随着对比方式的不同对基于正念的干预与自我同情的关系会产生不同的调节作用, 而群体和测量工具对基于正念的干预与自我同情的关系并无调节效应。
