工作场所排斥与员工心理健康、工作满意度的关系：性别的调节作用

为考察工作场所排斥问卷（WOS）在国内的适用性,以及不同性别员工在遭受工作场所排斥后的心理健康和工作满意度状况,采用中文版WOS对437名员工进行调查,结果表明：（1） 9题版WOS为单维结构,信效度良好;（2）性别在工作场所排斥与心理健康、工作满意度的关系中起调节作用。由此,修订后的中文版WOS可以作为评定工作场所排斥的工具使用;女性受工作场所排斥的负面影响更大。     

汉语简单否定陈述句理解的心理模拟过程

采用自定步速阅读的方法, 从体验认知的角度探索了汉语简单否定句的动态理解过程。以具有对立谓词的汉语陈述性的肯定句和否定句为实验句, 以与否定句的两种状态相对应的图片为实验图片, 并构成句子-图片匹配/不匹配两种匹配状态。研究结果表明, 实验1在以250 ms为间隔时间的条件下, 肯定句和否定句的理解有显著的匹配效应; 实验2以750 ms为间隔时间, 则未表现出匹配效应, 而实验3以1500 ms为间隔时间, 肯定句和否定句的理解又表现出显著的匹配效应。实验结果证明, 具有对立谓词的简单的汉语否定句理解的心理模拟过程, 并不像两步模拟假设所设想的那样遵循着先模拟被否定状态再模拟实际状态的顺序, 而是在理解的初期就完成了对事件的实际状态的模拟。     

中文阅读过程中的副中央凹预视效应

副中央凹预视效应指当读者正注视某个词(即位于中央凹的词n)时, 可以获得词n右侧词(即位于副中央凹词n+1或词n+2)的部分信息。在阅读过程中读者能否从副中央凹预视到信息, 会直接影响他们的阅读效率。因此, 探讨阅读过程中的副中央凹预视效应产生的条件、影响因素及机制, 成为阅读心理学需要解决的基本问题之一。本文系统总结了中外文阅读过程中副中央凹预视效应的研究进展, 包括副中央凹预视效应的研究范式, 中外文阅读过程中副中央凹预视的信息类型、不同类型信息预视加工的时间进程, 以及空间上获得预视信息的范围。最后提出中文阅读过程中副中央凹预视研究需要解决的几个关键问题。     

客体工作记忆任务中大脑皮层活动的记忆负荷效应

利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了20名正常被试完成不同负荷客体任务时的皮层慢电位（slow cortical potentials,简称sp成分）,实验发现：背侧前额叶在刺激呈现后的700ms到1400ms出现记忆负荷效应,高负荷任务诱发的sp成分显著负于低负荷任务;低负荷任务诱发的sp成分在左前额区（500~1800ms）、左前额-中央区（700~1800ms）、左中央-顶叶区（1000~1400s和1800~4800ms）、右前额区（1800~4800ms）和右前额-中央区（1400~4800ms）显著负于高负荷任务,出现记忆负荷效应,但这种负荷效应在左右大脑半球所反映的心理意义可能不同     

Genetic and environmental sources of continuity and change in teacher‐rated aggression during early adolescence

Genetic and environmental sources of continuity and change in aggression were studied in a sample of 1,041 twin pairs (364 monozygotic; 348 same‐sex dizygotic; and 329 opposite‐sex dizygotic) as part of an ongoing, population‐based Finnish twin‐family study. At ages 12 and 14, the twins' aggression was assessed by their classroom teachers, using a rating form of the Multidimensional Peer Nomination Inventory. Genetic and environmental sources of continuity and change were studied by fitting a longitudinal bivariate Cholesky decomposition model. Longitudinal model‐fitting results indicated that both genetic and environmental factors influenced continuity in aggression during this 2‐year period, but the age‐to‐age correlation of these factors differed by sex. Continuity in boys' aggression was mediated by genes and common environmental factors; in girls, in contrast, continuity was due primarily to common environmental, and to a lesser degree, unique environmental factors. Genes and unique environments contributed to change in aggression in both sexes. Aggr. Behav. 31:1–13, 2006. © 2006 Wiley‐Liss, Inc.     

The Dark Triad Traits,Humor Styles,and Schadenfreude: Others' Misery as the Devil's Laughing Stocks1

This research investigated the relationships of the Dark Triad traits, humor styles, and schadenfreude with 169 participants who completed the Short Dark Triad, the Humor Style Questionnaire, and a measure of schadenfreude. Significant correlations imply that those with salient dark traits (psychopathy, Machiavellianism, narcissism) elicit pleasure from others' misfortune. Additionally, schadenfreude can be a product of self-defeating and aggressive humor styles. Indirect effect analysis revealed the significance of the indirect effect of the measured aggressive humor style on the Dark Triad's direct effects on schadenfreude. These results imply that those with salient Dark Triad traits enjoy others' misery as a means to undermine them. Hence, individuals with salient Dark Triad traits tend to engage in downward social comparison.     

Method effects due to social desirability as a parsimonious explanation of the deviation from unidimensionality in LOT-R scores

Dispositional optimism measured by the Life Orientation Test (Revised; LOT-R, Scheier et al., 1994) was originally proposed as a unidimensional construct pertaining to individual differences in positive outcome expectancies. However, factor analytic research has suggested two separate “optimism” and “pessimism” factors associated with positively and negatively worded items respectively. Using confirmatory factor analysis with data from N = 658 students it is shown that a general optimism model with method effects of the positively worded items fits even better than the “optimism–pessimism” model in terms of the AIC statistic, which accounts for both model parsimony and model fit. Furthermore, an attempt is made to explain the method effects by social desirability: impression management, one of two components of socially desirable responding, correlates significantly with the method factor whereas the other component, self-deceptive enhancement, is related to the general optimism factor. Thus it is shown that the deviation from unidimensionality of observed scores does not imply deviation from unidimensionality of optimism when method effects are incorporated in the model.     

The Role of Strategy in Mixed-Gender Group Interactions: A Study of the Television Show “The Weakest Link”

This paper studies mixed-gender group interactions in a strategic game where group members are sequentially eliminated till a single winner takes all. Study 1 tests the hypothesis that female contestants are retained till final rounds where they are eliminated. Using observational data from the US television show The Weakest Link (20 shows), results show that females are finalists but not winners. In a laboratory study (Study 2, 67 Berkeley undergraduates), we show that this effect is attenuated when winnings are shared among finalists (versus one winner takes all) due to the reduction in competitive pressures in the context. This research was supported in part by the Junior Faculty Research Grant awarded by the University of California at Berkeley to the second author.     

大学生对两个原因交互作用效应的评估

用大学生被试的两个实验考察人们对两个原因交互作用效应的定性评估和定量评估。实验结果表明,被试的定性评估与交互作用对比的性质相一致,而与因果力的性质不相一致;被试的定量评估随交互作用对比值增加而增加,而不受因果力的影响。实验结果一致支持交互作用对比标准,而不支持因果力标准和交叉乘积比率标准。这不同于以往的有关研究结果     

青少年外向/宜人性人格、互联网服务偏好与"网络成瘾"的关系

该研究采用问卷法,以481名中学生为被试,通过无约束结构方程模型分析方法探讨了外向性、宜人性人格特征与互联网服务偏好的交互作用对网络成瘾的影响。研究发现在对网络成瘾的影响上,青少年宜人性人格特征与互联网社交服务偏好存在显著的交互作用,但与互联网娱乐、信息和交易服务偏好的交互作用不显著。外向性人格特征与互联服务偏好不存在显著的交互作用。(1)从平均影响来看,外向性、宜人性、互联网社交、娱乐和交易使用偏好能够正向预测网络成瘾,互联网信息使用偏好对网络成瘾没有显著的预测效果;(2)在宜人性高分组中,互联网社交服务偏好与PIU的正向关系要强于宜人性低分组。斜率检验表明对于低宜人性人格的青少年来说,互联网社交服务偏好不易导致其成瘾,而对高宜人性人格的青少年而言,互联网社交服务偏好反而容易导致其成瘾。
