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。

Interactive Effects of Team and Task Shared Mental Models as Related to Air Traffic Controllers' Collective Efficacy and Effectiveness

We assessed the influence of task and team shared mental models (SMMs) on team effectiveness, as mediated by collective efficacy. Using a sample of 422 air traffic controllers representing 43 Navy teams from land-based towers, task SMMs exhibited a significant linear relationship with team effectiveness, whereas team SMMs did not. Moreover, the interaction of team and task SMMs was positively related to team effectiveness. Collective efficacy was found to mediate the relationship between task SMMs (but not team SMMs or their interaction) and team effectiveness. Results are discussed in terms of the complex nature of SMMs and team outcomes.     

Examining the convergent validity of shared mental model measures

Despite widespread interest in shared mental models (SMMs) within teams and groups and an extensive empirical literature examining SMM?Cperformance links, very little is known about the convergent validity of commonly used measures of SMMs. In this study, two-person teams (n = 96) engaged in a complex flight task and completed three SMM measures: concept mapping, paired ratings, and causal mapping. Task-based sharedness scores were compared across the measures. Analyses were conducted in two ways: using SMMs of actual team members (n = 96 pairs) and using the SMMs of pairs of participants who worked separately but for whom similarity indices were calculated after the study (n = 18,240). The purpose of the latter pairs, coined pseudo-partners, was to create a sample with considerable power to test the convergent validity of the SMM measures. The results call into some question the convergent validity of these task-based SMM measures.     

Investigating linear and interactive effects of shared mental models on safety and efficiency in a field setting

Linkages between 2 types of shared mental models (SMMs)--that is, positional-goal interdependencies and cue-strategy associations--and effectiveness in an air traffic control environment were investigated. Two types of SMMs were expected to contribute uniquely, as well as interact, to predict tower safety and efficiency. Using SMM data from 306 air traffic controllers, and corresponding archival efficiency and safety measures for 47 airports, the authors found no significant linear relationships between SMMs and either outcome measure. However, the 2 SMMs interacted with one another to predict both outcomes. Results are discussed in terms of the importance of measuring multiple types of SMMs, the examination of complex relationships, and the importance of indexing decisions.     

团队心智模型相似性与正确性对团队创造力的影响

现代组织越来越依赖团队进行创造与创新活动, 团队创造力成为理论与实践共同关注的热点问题。最新理论指出, 与个体类似, 团队也是信息加工者, 团队决策实质上也是信息搜寻、编码、存储和提取的认知加工过程。从团队认知角度开展研究是团队创造力领域的新方向。鉴于此, 本研究从团队认知的角度出发, 探讨共享心智模型与团队创造力之间的关系。基于80个信息平台运行维护团队的数据, 研究结果表明, 心智模型的相似性与正确性均能影响团队创造力, 但方向正好相反。心智模型相似性负向预测团队创造力, 而心智模型正确性则正向预测团队创造力。两者还共同影响团队创造力, 当成员心智模型正确性高且相似性低时, 团队创造力最高; 而当成员心智模型彼此相似但错误时, 团队创造力最差。本研究首次将团队认知和团队创造力两个研究领域结合起来, 研究结果有望丰富和拓展两个领域研究成果。     

团队作业与团队互动两类共享心智模型的发展特征

共享心智模型指团队成员关于团队作业、策略、团队情境、团队互动等的共同的知识结构,根据内容不同可以分为团队作业模型和团队互动模型两类。该研究通过实验室实验探讨两类共享心智模型的发展特征。132名大学生组成44个3人团队,随机分为团队绩效反馈组和无团队绩效反馈组。采用相似性评定法在团队执行作业前、中、后三次测量两类共享心智模型。结果发现：（1）共享心智模型随团队运作时间增加而发展;（2）团队互动模型形成和发展的难度高于团队作业模型;（3）团队绩效反馈对两类心智模型发展的作用不同,反馈加速了团队作业模型的发展速度,但却是团队互动模型能否得以发展的决定性因素。两类共享心智模型的不同发展特征应归因于两者特异性高低的不同     

Psychological capital as a team phenomenon: Mediating the relationship between learning climate and outcomes at the individual and team levels

Psychological capital is a positive psychological state that influences employees’ behaviors and attitudes. Research has only recently begun to examine the phenomenon as a shared psychological team state. The purpose of this research is to examine the mediating role of team psychological capital in the relationship between learning climate and outcomes at the individual and team levels. The findings, which were carried out among 82 school management teams, indicated a positive relationship between learning climate and the team’s psychological capital, and between the team’s psychological capital and the individual’s job satisfaction and the team’s organizational citizenship behavior (OCB). It was also found that team’s psychological capital mediates the relationship between the team’s learning climate and job satisfaction, and between learning mechanisms and the team’s OCB. The findings might encourage research into psychological capital as a team phenomenon and encourage decision-makers to develop ways of reinforcing psychological capital among teams.     

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.     

Selection in Teams: An Exploration of the Teamwork Knowledge,Skills, and Ability Test

In 1994, Stevens and Campion introduced the Teamwork Knowledge, Skills, and Ability test (teamwork KSA test) for selecting employees for team–based organizations. Using experimental data from 57 ad hoc student teams (N = 227), we examined this test's relationship with both the behavior of the assigned leader in a team and the behavior of the other team members, respectively. We found that the teamwork KSA test successfully predicted individual team member behavior as indexed by external raters (r= .31) and peers (r= .34) such that higher scores on the teamwork KSA test related to greater individual effectiveness within the team. The teamwork KSA test was unrelated to the behavior of the assigned leader in the teams studied. Self–efficacy for teamwork was not related to individual behavior in teams, nor did it moderate the relationship between the teamwork KSA test and individual performance in teams. Limitations as well as directions for future research in team selection are discussed.     

共享心智模型影响团队绩效的权变模型

共享心智模型指团队成员关于团队关键要素的共同的知识结构, 诸多研究表明其能有效提高团队运作效能。本研究从权变的角度入手, 以负责通讯网络监控与维护的106个高技术团队为分析对象, 探讨团队的共享心智模型与团队绩效的关系, 并揭示团队互依性作为权变因素对共享心智模型与团队绩效关系的调节效应。层次回归分析结果表明, 共享心智模型能显著预测团队绩效, 而团队互依性则负向调节两者之间的关系, 即在互依性程度较低的团队里, 共享心智模型才显著提高团队绩效。作者从共享心智模型的测量和权变因素的作用两个角度展开讨论, 并基于此提出了后续的研究方向。     

团队权力分布差异对团队冲突的影响：程序公平和合法性的作用

近年来团队权力分布差异与团队冲突间关系受到了学界较大关注, 但相关研究结果仍存在分歧。通过对70个工作团队的调查, 探讨了团队权力分布差异对团队冲突(任务冲突、关系冲突)作用的边界条件。结果发现, 程序公平调节了两者间关系：当程序公平较高时, 团队权力分布差异与任务冲突、关系冲突负相关; 当程序公平较低时, 团队权力分布差异与任务冲突、关系冲突正相关。此外, 被中介的调节模型分析显示, 团队合法性感知中介了程序公平的上述调节作用。     

A MULTILEVEL INVESTIGATION OF LEADER– MEMBER EXCHANGE,INFORMAL LEADER EMERGENCE,AND INDIVIDUAL AND TEAM PERFORMANCE

This study examines the antecedents and outcomes of informal leader emergence in work teams. Drawing upon research in vertical and shared leadership, we hypothesized that the relationship between leader‐‐member exchange (LMX) quality and employees’ emergence as informal leaders is moderated by team shared vision such that there is a positive (negative) LMX—leader emergence relationship for teams with high (low) shared vision. Informal leader emergence, in turn, was expected to relate to higher individual and team performance. Results based on multisource and multimethod data collected at 3 points in time (361 followers in 74 work teams) provided support for these hypotheses. The findings highlight the role played by formal leaders and team shared vision in jointly promoting or inhibiting informal leader emergence and thereby impacting individual performance and team effectiveness.     

KNOWLEDGE WORKER TEAM EFFECTIVENESS: THE ROLE OF AUTONOMY, INTERDEPENDENCE, TEAM DEVELOPMENT, AND CONTEXTUAL SUPPORT VARIABLES

This study investigated how autonomy, interdependence, and team development, along with process and contextual support variables, were related to the effectiveness of teams of "knowledge workers." The sample included 231 knowledge workers from 27 work teams. Team members completed surveys measuring the design, process, and contextual factors. Effectiveness measures included multiple key stakeholder evaluations of team performance and self-report measures of attitudinal outcomes. The results suggest that interactions among design, process, and contextual support factors have important implications for team effectiveness. In particular, the positive relationship between team autonomy and team job motivation was reduced as teams worked under more interdependent conditions. This interaction effect also varied across the types of autonomy (e.g., planning-related, product-related, and people-related) the team was given. Results also demonstrated that the relationship between job motivation and team process behaviors (helping, sharing, and innovating) was more positive in teams who were developmental mature. Process behaviors were positively related to effectiveness, but those relationships became more positive in the presence of certain contextual factors (high-quality goals and efficient information transmission), and less positive in the presence of others (feedback and time pressure). Future research needs and practical implications of these results are discussed.     

Does diversity in team members’ agreeableness benefit creative teams?

Although deep-level diversity among team members are often discussed as important catalysts of team creativity, little is currently understood about the impact of diversity in team members’ personality on team creativity and team satisfaction. We propose that diversity in team members’ agreeableness would reduce the effectiveness of creative teams through its impact on team conflict experienced. To test our hypotheses, we recruited 93 student teams to participate in a laboratory study where each member had their personality traits assessed before engaging in a team creativity task. We found that diversity in team members’ agreeableness was positively associated with team task conflict experienced which, in turn, was negatively associated with team creativity. Additionally, we found that diversity in team members’ agreeableness was positively associated with team relationship conflict, which, in turn, was negatively associated with team satisfaction. Implications and future directions are discussed.     

团队人格组成、团队过程对团队有效性的作用

由于团队对组织的重要性,团队有效性的研究倍受关注。通过对342个大学生短期团队完成决策任务的研究,旨在探讨团队人格组成与团队中间过程对团队有效性的作用机制。研究以自陈式问卷调查收集数据,采用层次回归与结构方程模型进行统计分析。研究结果表明：团队过程变量（协作、信念、凝聚力）在团队人格组成（外向性、宜人性、神经质）与团队有效性之间起中介作用,横断研究的I-P-O整体模型得到验证     

Does Teaming Obscure Low Performance? Exploring the Temporal Effects of Team Performance Diversity

Organizations are increasingly using team-based projects to achieve goals. As such, it is important to understand how team members (e.g., their differences) influence team outcomes such as effectiveness. In the present study, we examine performance diversity, differences in members’ past performance, as an antecedent to team effectiveness. In addition, we assessed the length of time the group performed together as a moderator and social loafing among members as a mediator of the performance diversity—team effectiveness relationship. Using multisource data for 673 individuals in 139 project teams, we found that performance diversity had an increasingly negative effect for groups that were together longer. Specifically, greater diversity resulted in more social loafing, thereby diminishing team satisfaction and supervisor-rated team performance.     

Solidarity in STEM: How Gender Composition Affects Women’s Experience in Work Teams

The relationships among the percentage of women in a team and women’s sense of team identification and collective efficacy as well as team performance was examined. We explored these relationships in a sample of student teams conducting a semester-long social science research project within the context of science and technology-focused university. Findings with 95 U.S. college students (43 women) show that women experience higher team identification and collective efficacy as the percent of women teammates increases. Additionally, women’s team identification and collective efficacy mediate the relationship between the percentage of women on the team and overall team performance. Interestingly, the number of men on the team did not influence men’s sense of team identification, collective efficacy, or team performance. This research has implications for team composition. Specifically, when navigating diversity in teams, managers and leaders should aim to build teams that are composed of multiple women versus an approach that divides women up among various teams. In doing so, managers can better secure conditions for the development of positive teamwork experiences and, ultimately, performance.

     

Personality,Self-Efficacy and Functioning in Management Teams: A Contribution to Validation

The relationship between individual difference variables and the contribution to team functioning was examined in 58 members of management teams. Extraversion and self-efficacy for working in teams were related to attraction to the team, which in turn was related to a rating of team effectiveness. Extraversion was also related directly to team effectiveness. The relationship between conscientiousness and team functioning was not clear. The results are considered supportive for the validity of self-efficacy for teams and extraversion as indicators of the ability and propensity of individuals to contribute to the functioning of management teams.     

冲突对绩效的影响：个体、团队宜人性的调节作用

以往个体和团队冲突研究主要考察了个人特征或团队特征对冲突结果的影响, 而尚未充分关注冲突管理过程中个体特征与团队特征间的交互效应。基于个人-团队匹配理论, 本研究探讨了个体层面宜人性与团队层面宜人性异质性对团队中个体冲突(关系冲突、任务冲突)和工作绩效间关系的影响。基于来自64个银行服务团队(包含339名下属和64名主管)的多来源、多时点纵向数据, 本研究所得结果显示：(1)关系冲突显著负向影响工作绩效, 任务冲突对工作绩效的影响不显著。(2)个体宜人性能够显著减弱关系冲突对工作绩效的负面影响, 而增强任务冲突对工作绩效的正向影响。(3)关系/任务冲突、个体宜人性和团队宜人性异质性间存在着三重交互效应, 共同影响工作绩效。具体而言, 当团队宜人性异质性水平较低时, 个体宜人性对关系/任务冲突与工作绩效间关系的调节作用更加显著。
