双价效应及其认知机制

任务转换时, 如果一个刺激不仅包含当前任务的特征还包含另一任务的关联特征, 这样的刺激被称为双价刺激。双价刺激能影响个体对单价刺激的加工, 使个体对后续所有单价刺激的反应减慢, 这种现象被称为双价效应(bivalency effect)。研究者发现双价效应具有一定的普遍性和稳定性。对双价效应的理论解释主要有情境捆绑说和基于经验的预测模型。双价效应的产生与额外视觉特征的提取及自上而下的认知控制调整有关, 前者主要与颞-顶联合区的激活有关, 后者主要与背侧前扣带回以及前辅助运动区的激活相关。     

团队任务冲突与团队领导行为及团队学习的关系研究

本研究旨在探讨项目团队领导基于角色的不同行为对团队内部的任务冲突互动,以及团队学习的影响.以128个项目团队为研究对象进行的问卷调查结果表明,在领导行为与团队学习的关系中任务冲突存在显著的中介效应.其中,团队领导的促进者与指挥者角色行为完全通过任务冲突的中介传导,对团队学习产生影响,;而领导的创新型行为则通过任务冲突的部分中介作用,产生对团队学习的正向影响.     

家庭环境类型与青少年亲子冲突解决的关系

以北京829名普通中学生为被试.探讨了家庭环境类型与亲子冲突解决的关系.结果表明: (1)高亲密度、高情感表达、低矛盾性的家庭在亲子冲突解决的关系目标上的得分显著高于其它类型家庭;低亲密度、低表达性、高矛盾性的家庭在权力、公平、自认和自主目标上的得分显著高于其它类型家庭. (2)高亲密度、高表达性、低矛盾性的家庭更多使用积极的冲突解决策略;低亲密度、低表达性、高矛盾性的家庭更多使用消极的冲突解决策略.说明不同家庭环境类型下的青少年亲子冲突解决有不同的特点.     

Interactive effects of work group and organizational identification on job satisfaction and extra-role behavior

Past research has focused on the differential relationships of organizational and work group identification with attitudes and behavior. However, no systematic effort has been undertaken yet to explore interactive effects between these foci of identification. We predicted that in cases of positive overlap of identifications (i.e. high work group and organizational identification) identifications are more strongly associated with employee job satisfaction and extra-role behavior than when only one of the identifications is high—that is, the one identification augments the influence of the other. These hypotheses were tested and supported with data from two samples of bank employees (N = 358) and travel agency employees (N = 308).     

Positive and negative effects of family involvement on work-related burnout

We aimed to explain the influence of family involvement on feelings of burnout among employees who combine work and family tasks. As proxies for family involvement, we used the family structure (partner, number and age of children) and family tasks (e.g. hours spent on household chores). We compared conflict theory and enrichment theory, and investigated how well they explain the relationship between family involvement and feelings of burnout. Based on a sample of 1046 employees at 30 Dutch organizations, the results showed that the presence of young children and doing more household chores were positively related to feelings of burnout, whereas having children reduced employees’ feelings of burnout. We also investigated interaction effects of gender and gender-role norms. We conclude that family life can reduce work-related burnout and that for men, the relationship between family involvement and feelings of burnout differs depending on whether they have traditional or modern gender-role norms.     

Why dieters fail: Testing the goal conflict model of eating

A new theory of eating regulation is presented to account for the over-responsiveness of restrained eaters to external food-relevant cues. According to this theory, the food intake of restrained eaters is characterized by a conflict between two chronically accessible incentives or goals: eating enjoyment and weight control. Their difficulty in weight control is due to their behavioral sensitivity to eating enjoyment and its incompatibility with the eating control goal. Accordingly, exposure to food-relevant stimuli primes the goal of eating enjoyment in restrained (but not unrestrained) eaters, resulting in an inhibition of weight control thoughts. Three studies are reported that support these assumptions. Study 1 demonstrates a substantial relation between Eating Restraint and measures of ambivalence towards eating. Studies 2 and 3 show that priming eating enjoyment decreases the accessibility of eating control concepts. The results are discussed in the context of current research on the psychology of obesity and restrained eating.     

When and how do differences matter? An exploration of perceived similarity in teams

In this paper, we directly assess perceived similarity—the degree to which members view themselves as having few differences—because we want to understand when teams notice diversity on various member characteristics and how they interpret it. Our results indicate social category diversity was related to initial estimates of both perceived social category similarity (SCS) and perceived work style similarity (WSS). And, whereas perceived SCS did not change over time, perceived WSS decreased significantly over the period of our study. We suggest this change in perceived WSS can be explained by an information-processing/decision-making framework. We found informational diversity was positively related to conflict in teams, and in turn conflict was negatively related to subsequent estimates of perceived WSS. However, informational diversity was positively related to information sharing in teams, which in turn was positively related to subsequent estimates of perceived WSS. Finally, these updated estimates of perceived WSS affected subgroup formation and team process effectiveness. We discuss how our research explores the subjective experience of diversity by team members, provides a dynamic view of the relationship between diversity and team outcomes, and informs emerging theory about the activation of faultlines in teams.     

Work–Family Conflict: The Importance of Family-Friendly Employment Practices and Family-Supportive Supervisors

In the study reported in this paper, we examined the relationship between the use of four family-friendly employment practices (i.e., telecommuting, ability to take work home, flexible work hours, and family leave) and work–family conflict. In addition, we examined whether reporting to a family-supportive supervisor was related to the use of the four practices and to work–family conflict. We found that the use of three of the four practices was related to work–family conflict. In addition, our results showed that reporting to a family-supportive supervisor was related to the use of certain practices and to work–family conflict.

民族冲突的社会心理机制

民族冲突是影响社会和谐与稳定的重大现实问题, 其社会心理机制是尚未解决的重要科学问题。本项目拟以我国西部地区藏族为例, 纳入社会威胁情境因素, 并整合社会认同理论和社会类别的心理本质论框架下的群际冲突研究。其基本理论命题是：民族冲突形成并不是单一因素所致, 而是基于个体层面、群体层面和社会情境层面的多水平变量相互作用的结果。本项目拟通过既相对独立又彼此关联的三个实证研究, 旨在考察少数民族关于“民族”的心理本质论对民族冲突的预测和影响作用, 探索民族身份延伸和社会威胁情境在其中的影响作用, 从而揭示民族冲突形成的社会心理机制, 旨在为构建民族冲突的预警机制模型奠定基础, 为跨越民族界限、实现多民族和谐共处和完善民族政策提供科学依据。
