公平规范执行中内群体偏爱的心理发展机制

如何揭示群体规范和公平价值在个体心理发展中的作用机理, 提升儿童-青少年在群际互动当中的公平感知与规范执行, 是教育心理领域的关键问题。公平规范执行中内群体偏爱现象是近年来的研究热点之一, 然而先前研究存在以下不足：1)大多采用问卷法, 易受社会赞许性的影响, 存在言行不一致的情况; 2)大多采用情景实验, 聚焦社会互动的最终行为输出端, 无法实时有效地把握社会决策的动态进程; 3)脑成像研究仍以fMRI技术为主, 侧重于评估认知加工潜在的脑区激活模式及各脑区间的功能连接, 缺乏对群际公平规范执行中大脑激活动态模式的精确把握。针对这些不足, 本项目从资产分配情景出发, 以儿童和青少年为研究对象, 联合运用认知、行为、眼动和电生理等多层次测评手段, 对公平规范执行中内群体偏爱的发生过程进行认知解析, 探讨认知控制和心智化在其间的关键作用机制及其心理发展轨迹。研究结果将服务于中小学管理中的德育教育, 引导与培养学生的公正感与行为。     

付出回报失衡与高校青年教师的焦虑：心理契约破裂的中介作用和过度承诺的调节作用

基于付出回报失衡模型,考察了高校青年教师的付出回报失衡与焦虑的关系。对336名高校青年教师进行了多时间点调查。结果显示：（1）付出回报失衡对高校青年教师的焦虑有显著正向预测作用;（2）付出回报失衡通过心理契约破裂间接影响高校青年教师的焦虑;（3）相较于低过度承诺教师,高过度承诺教师的付出回报失衡经由心理契约破裂对焦虑的影响更为突出。研究结果揭示了付出回报失衡对焦虑影响的过程机制和边界条件,对高校青年教师工作焦虑的改善有一定启示。     

受害者视角下职场不文明行为对组织公民行为影响的双路径机制

本文基于资源保存理论,探讨职场不文明行为对组织公民行为的影响机制及作用边界。通过问卷调查315份员工和领导的配对样本数据,结果表明：职场不文明行为负向预测组织公民行为,情绪耗竭、组织自尊中介了职场不文明行为与组织公民行为间的关系;心理韧性调节了情绪耗竭、组织自尊在二者间的中介作用。     

青少年创伤后应激障碍症状与网络成瘾症状的关系：惩罚敏感性和孤独感的中介及性别的调节

汶川地震9.5年后,对汶川县和都江堰市767名中学生进行调查,考察惩罚敏感性和孤独感在创伤后应激障碍症状和网络成瘾症状之间的多重中介作用及性别差异。结果发现：（1）PTSD症状正向预测网络成瘾症状,并分别通过惩罚敏感性、孤独感的单独中介作用及两者的链式中介作用显著预测网络成瘾症状;（2）女性的PTSD症状显著正向预测网络成瘾症状,并分别通过惩罚敏感性和孤独感间接影响网络成瘾症状;男性的网络成瘾症状仅被PTSD症状正向预测。     

四周简易正念减压训练对初中生焦虑的影响

选取68名初一学生并以班级为单位分为四周正念减压(mindfulness-based stress reduction,MBSR)训练组和对照组,探讨四周MBSR对初中生焦虑和正念水平的影响,以及训练效果是否存在基线效应与性别差异。结果发现:(1)四周MBSR可以提高初中生的正念水平,缓解其焦虑情况;(2)“不判断”和“特质焦虑”基线水平影响正念训练的效果;(3)四周MBSR对初中生的训练效果不存在性别差异。     

Some subordinates are more equal than others: Play fihgting amongst adult subordinate male rats

Adult male rats living together form dominance relationships, with one dominant and the remainder adopting subordinate roles. In previous studies, it was shown that in adult male pairs, the subordinate rat initiates more playful contacts and retains a more juvenile response to the playful contacts by the dominant. In this experiment, triads were used to examine the play between subordinate males. The subordinates directed fewer playful contacts to each other than to the dominant rat, and there was a symmetrical play relationship between the subordinates. After the dominant was removed from the colony, one subordinate became the dominant. Playful interactions amongst these pairs increased, with the subordiante intiating more playful contacts than the dominant. Furthermore, from a similarly low frequency of juvenile-type response to playful contact to each other when in triads, the subordinate in the dyads increased its frequency of juvenile responses to the dominant partner. This supports the hypothesis that the playful behavior of subordinate male rats towards the dominant is an adaptive response, playful behavior of subordinate male rats towards the dominant is an adaptive response, serving a “friendship maintenance” function. Finally, when in triads, one subordinate was more playful with the dominant than the other subordinate. It was the least playful subordinate that was the most likely to become the dominant. This sugests that within a colony, not all subordinates are the same. © 1993 Wiley-Liss, Inc.     

Pregrouping aggression and defense scores influences alcohol consumption for dominant and subordinate rats in visible burrow systems

Five male/two female rat colonies were established in visible burrow systems, with males selected for pregrouping attack scores and also evaluated in open field and cat odor tests. Dominant-subordinate pregrouping attack differences suggested that the males becoming dominant are those showing more persistent and higher level attack. For six colonies showing dominant-subordinate behavioral differences, pregrouping defense tests failed to predict subordinate status. However, pregrouping defense scores were reliably correlated with subordinate pre-postgrouping change scores for voluntary ethanol consumption. Subordinates showed higher ranked ethanol consumption than dominants, but these groups were not different on pregrouping ethanol consumption. Subordinate postgrouping ethanol consumption was positively correlated with pregrouping attack toward an adult intruder, consonant with previous findings that highly aggressive subordinates are the targets of more intense attack by dominants. These results provide further support for a view that subordination stress increases voluntary ethanol consumption in male rats and suggest some additional individual differences factors that may be involved in increased ethanol consumption for male subordinates. © 1992 Wiley-Liss, Inc.     

Mechanisms of Empowerment: Psychological Processes for Members of Power-based Community Organizations

The paper reports a study of participatory experiences among members of power-based community organizations. A path model of psychological empowerment was tested. Perceived relational characteristics of the community organization were hypothesized as exogenous to participation, perceived organizational power and psychological empowerment. An alternative model was reproduced with the strongest relationships between perceived organizational intimacy and psychological empowerment and an inverse relationship between perceived organizational regulation and perceptions of organizational power.     

Fighting experiences and natural killer cell activity in male laboratory mice

There is currently much interest in the potential impact of psychological factors on immune responses. An attempt was made to assess the effects of dominant/subordinate polarity in male mice on the cytotoxic activities of their natural-killer (NK) cells. On the basis of repeated agonistic encounters, categories of subordinate and dominat animals were selected. These animals were compared with manipulated controls (introduced to a novel test cage without an opponent on each occasion) and undisturbed controls (who remained in isolation without manipulation). In terms of NK activity, immunosuppression was observed in both dominant and subordinate categories when compared to undisturbed controls. There were, however, no differences between the fighting exposed subjects and the manipulated controls, suggesting that stress accounts for any changes. © 1994 Wiley-Liss, Inc.
