团队多样性与组织支持对团队创造力的影响

采用实验法在专业异质性与群体断层两个水平上操纵团队多样性, 通过两个实验考察团队多样性与组织支持的交互作用对团队创造力的影响。研究结果表明：(1)在独创性维度上, 专业异质团队在工具支持条件下的独创性显著高于专业同质团队, 情感和物质支持条件下二者差异不显著。当团队出现群体断层时, 情感支持与工具支持具有同样的促进作用, 即在这两种组织支持下, 强断层团队的独创性显著高于弱断层团队; 物质支持条件下二者差异不显著。(2)在适宜性维度上, 组织支持的主效应显著, 两个实验一致地发现物质支持条件下的适宜性显著高于情感支持和工具支持。本研究从团队多样性与组织支持交互作用的角度考察不同复杂程度、不同组织目标的多样性团队所需要的组织支持条件, 对促进团队创造力具有一定的理论与实践价值。     

A CONTRIBUTION TO THE DEBATE ON SCIENCE AND FAITH BY CHRISTIAN STUDENTS FROM ABIDJAN

The science and faith debate is dominated by Western voices. In order to enrich this debate, the authors study the discourses of different groups of Christian academics and master's students in francophone Africa. This article describes the process of reconstructing and analyzing the discourse of a group of master's students from Abidjan (Ivory Coast) with the help of group model building and focus groups. Three characteristic features that emerge from this discourse include the foundational position of faith, the central role of truth, and the ambiguous connotations of the term “science” in this context. The reconstructed discourse is then brought into conversation with the North Atlantic debate, with a special focus on the concept of scientism.     

Confidence in Dyadic Decision Making: The Role of Individual Differences

Groups typically express more confidence than individuals, yet how individual‐level confidence combines during collaborative decision tasks is not well understood. We prescreened 686 community members using a novel confidence measure (a true/false trivia test) intentionally designed to be difficult (accuracy rates were not significantly better than chance) and randomly assigned 72 individuals to collaborate on a matched version of the same test in dyads composed of two low‐confidence individuals, two high‐confidence individuals, or one of each (“mixed”). Consistent with past research, we found that the confidence expressed by dyads was higher than the confidence expressed by individuals; importantly, however, this pattern varied markedly by dyad type, with low‐confidence dyads showing the largest increase, mixed dyads showing a moderate increase, and high‐confidence dyads showing no increase—despite the fact that all dyads showed similarly low accuracy (about 55%). These results highlight the conditions under which groups express greater confidence than individuals and offer insights for the composition of collaborative decision‐making teams.

Using Response Surface Analysis to Interpret the Impact of Parent–Offspring Personality Similarity on Adolescent Externalizing Problems

Personality similarity between parent and offspring has been suggested to play an important role in offspring's development of externalizing problems. Nonetheless, much remains unknown regarding the nature of this association. This study aimed to investigate the effects of parent–offspring similarity at different levels of personality traits, comparing expectations based on evolutionary and goodness‐of‐fit perspectives. Two waves of data from the TRAILS study (N = 1587, 53% girls) were used to study parent–offspring similarity at different levels of personality traits at age 16 predicting externalizing problems at age 19. Polynomial regression analyses and Response Surface Analyses were used to disentangle effects of different levels and combinations of parents and offspring personality similarity. Although several facets of the offspring's personality had an impact on offspring's externalizing problems, few similarity effects were found. Therefore, there is little support for assumptions based on either an evolutionary or a goodness‐of‐fit perspective. Instead, our findings point in the direction that offspring personality, and at similar levels also parent personality might impact the development of externalizing problems during late adolescence. © 2017 The Authors.

For the Win: Risk‐Sensitive Decision‐Making in Teams

Risk‐sensitivity theory predicts that decision‐makers should prefer high‐risk options in high need situations when low‐risk options will not meet these needs. Recent attempts to adopt risk‐sensitivity as a framework for understanding human decision‐making have been promising. However, this research has focused on individual‐level decision‐making, has not examined behavior in naturalistic settings, and has not examined the influence of multiple levels of need on decision‐making under risk. We examined group‐level risk‐sensitive decision‐making in two American football leagues: the National Football League (NFL) and the National College Athletic Association (NCAA) Division I. Play decisions from the 2012 NFL (Study 1; N = 33 944), 2013 NFL (Study 2; N = 34 087), and 2012 NCAA (Study 3; N = 15 250) regular seasons were analyzed. Results demonstrate that teams made risk‐sensitive decisions based on two distinct needs: attaining first downs (a key proximate goal in football) and acquiring points above parity. Evidence for risk‐sensitive decisions was particularly strong when motivational needs were most salient. These findings are the first empirical demonstration of team risk‐sensitivity in a naturalistic organizational setting. Copyright © 2016 John Wiley & Sons, Ltd.     

领导-团队投入匹配对团队绩效的影响：团队满意度氛围的作用

基于领导-团队匹配的视角,研究以133名领导和645名成员的团队配对数据,采用二次多项式回归与响应面分析对领导工作投入与团队投入氛围的一致性匹配和不一致性匹配,以及团队满意度氛围如何影响团队绩效进行了探讨。结果发现：领导工作投入与团队投入氛围一致与不一致相比,团队绩效较好;并且一致性匹配具有加强效应,即当领导工作投入与团队投入氛围一致时,团队绩效随着双方投入的增加而提高;同时,团队满意度氛围在领导-团队投入的一致性匹配与团队绩效的线性关系中起到部分中介作用。     

555例危险行为高危青少年的心理干预：来自个体辅导和团体辅导的效果对照

对有较高风险发展为危险行为青少年的高危群体实施有针对性的心理干预是非常有价值的。本研究对青少年危险行为高危人群进行结构化的个体与团体心理干预,评估两种干预的即时效果和六个月的预后情况。采用《青少年健康相关危险行为问卷》等量表对16所中职院校的学生进行筛查,共555名学生参加本研究,被随机分为个体、团体和对照组并分别进行干预。结果发现：干预后,个体心理干预组被试的危险行为水平、心理健康以及抑郁和焦虑情绪均获得显著改善,并且6个月的预后效果依然明显,而接受团体辅导干预组仅在抑郁指标上有所改善,在危险行为评分、焦虑和心理健康水平上均没有明显的改善。研究认为,对危险行为易感青少年的心理干预应以经过良好设计的个体心理干预为主、团体干预为辅的方式进行。     

决策信心在信息化从众中的作用

研究采用JAS范式,通过操纵群体信息的性质（支持和反对）以及一致性程度,考察了决策信心在信息化从众过程中的作用。结果表明：（1）个体仅在接收到反对信息时会发生决策的偏转,表现出从众;（2）群体参照信息能够显著影响个体的信心：支持性的群体信息使个体的信心显著增高,而反对性的群体信息使信心显著降低,且表现出一种“负性偏向”（即个体对来自群体的负性信息更加敏感）;（3）在反对条件下,个体信心降低的程度能够很好地预测其决策偏转的概率,即信息化从众行为。这说明,决策信心可能在信息化从众中起着核心的中介作用——反对性的群体信息使得决策信心下降,而决策信心的下降导致了决策的偏转,从而表现出从众行为。     

群际威胁：影响因素与减少策略

群际威胁是增强消极刻板印象和偏见的重要因素, 甚至可以导致群际冲突或暴力。影响群际威胁的因素包括个体的感知与经验、群体特征、社会政策和法规等。通过改变社会分类, 模糊群际边界, 并创造群际接触的机会, 能够增加群际认同感, 降低群际威胁感, 减少群际偏见, 促进积极的群际关系。今后的研究需在不同的社会环境中完善群际威胁的理论模型, 并探索相关变量相互作用的内在机制, 为促进和改善群际关系提供理论依据。     

群体潜能对团队创新绩效的影响:转换型领导力的调节作用*

从团队创新内在动力视角出发,考察了群体潜能与团队绩效间的关系,并探索了转换型领导力对该作用过程的影响。研究发现:群体潜能与团队创新绩效有显著的正相关关系,该关系受到转换型领导力的调节,高水平的转换型领导力会增强两者的联系,低水平的转换型领导力会减弱两者的联系。
