知识差异和知识冲突对团队创新的影响

通过情景模拟实验比较了高低知识差异和有无知识冲突两个变量四个水平下的团队创新度。结果表明,知识差异和知识冲突存在着交互作用;当知识差异较小时,知识冲突对于团队创新度具有积极作用;当知识差异较大时,知识冲突所起的是一种震荡作用;当团队不存在知识冲突时,较高的知识差异对团队创新度具有积极作用;存在知识冲突时,高知识差异团队和低知识差异团队的创新度没有显著差异     

交互记忆系统研究回顾与展望

交互记忆系统是团队成员之间形成的一种彼此依赖的,用以编码、储存和提取不同领域知识的合作分工系统。其研究有助于发现高效工作团队如何处理解决问题所需要的信息,解释团队成员怎样通过发挥各自的专长去解决团队面临的问题。它是解释团队知识处理过程的一个机制。相关研究已有近20年的历史。文章从交互记忆系统的形成和维护、测量、影响因素及其对团队有效性的作用等几个方面对已有研究进行回顾,并指出其对管理研究和管理实践的借鉴意义及未来可能的研究方向     

复杂任务中共享心智模型间的缓冲作用

共享心智模型（SMM）指队员对于团队的共享心理表征。复杂任务下高的一致性难以获得且易造成小集体意识,SMM的作用在于相互间的调节及共享信念对低一致性的调节作用。为了验证这些假设对9名不同行业创业者进行访谈,对访谈材料进行内容分析得到心智模型关键概念,经过概化理论分析后得到了4个SMM：任务、队友、团队协作以及团队精神。使用心智模型问卷在ERP模拟实验中测量31个团队的绩效和SMM一致性。结果发现团队协作模型一致性是预测绩效的有力指标;团队构成不影响各个SMM一致性;任务模型一致性正向缓冲了团队协作模型一致性对绩效的作用;团队精神模型一致性正向缓冲了团队协作模型一致性对绩效的作用。研究提示SMM对冲突的引导及增进团队成员相互理解方面的作用。     

Cohesiveness, coach's interpersonal style and psychological needs: Their effects on self-determination and athletes' subjective well-being

GoalThe goal of this study was to test the impact of cohesiveness and coaches' controlling interpersonal style on athletes' perceptions of autonomy, competence and relatedness. A contextual motivation sequence [Vallerand, R. J. (1997). Toward a hierarchical model of intrinsic and extrinsic motivation. In M. Zanna (Ed.), Advances in experimental social psychology, Vol. 29 (pp. 271–360). New York: Academic Press.] was tested whereby social factors supporting the satisfaction of basic needs would increase the level of sport self-determination, which in turn, should predict subjective well-being in athletes.MethodThe proposed sequence was tested with 197 basketball players using structural equation modeling. The hypothesized model was supported.ResultsPerceptions of cohesiveness positively predicted the satisfaction of the basic needs. Perceptions of coaches' controlling interpersonal style negatively impacted feelings of autonomy. In turn, psychological needs predicted self-determination in sports ensuing greater sport satisfaction and positive emotions in sports. Tests of indirect effects also supported the mediating role of psychological needs and self-determination.ConclusionResults are discussed in light of the different types of motivational antecedents and their influence on the psychological needs.     

决策者-建议者系统模型的回顾与前瞻

自从决策者-建议者系统于1995年被提出以来,在决策领域引起了广泛的关注。通过总结决策者-建议者系统的研究范式和过程模型,比较了其与群体决策和团队决策的异同。目前在该系统模型中的主要研究变量涉及信任、建议者信心、专门知识、报酬、任务难度和相似性,已有的理论解释主要包括心理契约理论、态度改变理论、信念修正理论和沉没成本理论。未来的研究应当从变量关系、信任机制、建议提出和任务类型的角度进行专题探讨,并应当开展跨文化研究。     

School track and ethnic classroom composition relate to the mainstream identity of adolescents with immigrant background in Germany,but not their ethnic identity

Although developing a cultural identity is a core task for adolescents from immigrant families and the school is a highly important context in adolescence, to date, few studies have examined whether adolescents with particular cultural identities cluster in certain school contexts. Using data from a representative German sample including 7702 secondary school students of immigrant background from 1643 classrooms, we examined how the attended school track and four aspects of ethnic classroom composition relate to adolescents' cultural identity (i.e., their ethnic identity and mainstream identity). Two-level structural equation models indicated that students' ethnic identity was not systematically associated with the attended school track and the ethnic composition of the classroom. However, attending the academic school track, a classroom with a low proportion of classmates with immigrant background and frequently using German with classmates related positively to mainstream identity. Ethnic diversity and proportion of co-ethnics in class did not relate to mainstream identification. Our findings suggest that the ethnic identity of adolescents with an immigrant background in Germany is largely independent from the different socialisation contexts related to school tracks and the ethnic classroom composition. Yet, students' with a strong mainstream identity cluster in certain school contexts.     

A Forward Bias in Human Profile-Oriented Portraits

The spatial composition of human portraits obeys historically changing cultural norms. We show that it is also affected by cognitive factors that cause greater spontaneous attention to what is in front rather in the back of an agent. Scenes with more space in front of a directed object are both more often produced and judged as more aesthetically pleasant. This leads to the prediction that, in profile-oriented human portraits, compositions with more space in front of depicted agents (a “forward bias”) should be over-represented. By analyzing a large dataset (total N of 1,831 paintings by 582 unique identified European painters from the 15th to the 20th century), we found evidence of this forward bias: Painters tended to put more free space in front of, rather than behind, the sitters. Additionally, we found evidence that this forward bias became stronger when cultural norms of spatial composition favoring centering became less stringent.     

多团队成员身份及其作用机制

多团队成员身份(multiple team membership)是指员工在一段时间内以正式身份参与多个团队的工作状态及工作模式。以往围绕“团队数量”和“团队成员身份多样性”展开的研究未能对多团队成员身份的效应形成一致的认识和研究结论。因此,在系统回顾发展历程、厘清概念内涵的基础上,提炼出多团队成员身份“多重团队情境”和“多重团队认同”两个关键特征,并从注意力资源视角、社会网络视角和社会身份视角梳理并发展多团队成员身份的作用机制。最后,针对以往研究对多团队成员身份关键特征的关注缺失、社会网络视角和社会身份视角下有意义却尚未被探索的问题,综合技术和时间等因素提出了未来研究建议。     

The impact of virtuality on team effectiveness in organizational and non-organizational teams: A meta-analysis

We meta-analytically assess the virtuality-team effectiveness relationship using 73 samples of organizational teams (5738 teams) reporting on a wide range of productive (e.g. earnings), performance (e.g. customer ratings), social (e.g. cohesion), and team member (e.g. project satisfaction) outcomes. Our results suggest that in work organizations, virtuality is not a direct input—negative or positive—to team effectiveness. In contrast, using 109 samples of non-organizational teams (5620 teams), we show that virtuality is a significant negative input to team effectiveness. We also meta-analytically assess the issue of results generalizability from non-organizational to organizational settings, and find that overall, results from non-organizational studies largely fail to generalize to organizational virtual teams. Using moderator analysis, we explore a number of study features that may explain the poor results generalizability from non-organizational to organizational studies. We find that results from non-organizational studies using undergraduate students, short team duration, and laboratory settings drive the non-generalizability effect, whereas results from non-organizational studies using graduate students, longer team duration, and classroom settings produce results comparable to those of organizational studies of virtual teams. Theoretical, methodological, and practical implications are discussed.
