团队心智模型相似性与正确性对团队创造力的影响 总被引:1,自引:0,他引:1
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。 相似文献

他评法是一种有效的人格评价手段, 甚至在一些情境下比自评法更为有效。在现实准确性模型(the Realistic Accuracy Model, RAM)以及权重平均模型(the Weighted-average Model, WAM)的基础上, 对于影响他评准确性的因素进行了梳理, 涉及熟悉性、关系质量、特质可见度以及假设相似性等。针对目前研究中存在的问题, 提出要在中国文化背景下, 进一步拓展研究对象的取样范围, 在更多不同的情境下提高研究的生态效度, 同时采用更多的人格评价手段。 相似文献

The authors used a conditional accuracy function (CAF) method to compute the mean accuracy of multiple reaction time ranges, to investigate the association between aerobic fitness and the utilization of cognitive control strategy during preadolescence. Thirty-eight higher- and lower-fit children were grouped according to their cardiorespiratory capacity (VO2max) and completed a modified flanker task. Seventeen young adults were recruited as a reference group of maturation. The results showed that higher-fit children exhibited an adult-like performance pattern, and demonstrated increased overall response accuracy compared to lower-fit children, with a disproportionally larger increase in individual responses when the time allowed for discriminative processing was constrained. These findings suggest that aerobic fitness is associated with enhanced cognitive control and development of a more proactive control strategy during flanker task in preadolescent children. 相似文献

本研究通过蒙特卡洛模拟考查了分类精确性指数Entropy及其变式受样本量、潜类别数目、类别距离和指标个数及其组合的影响情况。研究结果表明:(1)尽管Entropy值与分类精确性高相关,但其值随类别数、样本量和指标数的变化而变化,很难确定唯一的临界值;(2)其他条件不变的情况下,样本量越大,Entropy的值越小,分类精确性越差;(3)类别距离对分类精确性的影响具有跨样本量和跨类别数的一致性;(4)小样本(N=50~100)的情况下,指标数越多,Entropy的结果越好;(5)在各种条件下Entropy对分类错误率比其它变式更灵敏。 相似文献

According to Hunt's match hypothesis, the accuracy of parents' beliefs about their children's abilities can influence the nature of the early learning experiences they provide. The present study examined the accuracy of parents' beliefs about their preschoolers' number development and relations to parent‐reported frequency of engaging children in number related experiences at home. Parents reported engaging their preschoolers more frequently in conventional numeracy activities, (i.e. counting and identifying numbers) than advanced number‐related activities (e.g. arithmetic) at home, though the frequency of advanced activities increased with the development of children's advanced number skills. Parents were most uncertain about their children's advanced number skills, though they demonstrated an overall tendency to overestimate their children's abilities across number tasks. Increased rates of overestimation and decreased rates of underestimation were associated with increased incidences of advanced activity engagement at home. Thus, results suggest guiding parents to understand their own children's numerical understanding in a wide range of number domains could promote more advanced at‐home number‐related activity engagement.

Abstract— A commonly used method for comparing groups of individuals is the analysis of variance (ANOVA) F test. When the assumptions underlying the derivation of this test are true, its power, meaning its probability of detecting true differences among the groups, competes well with all other methods that might be used. But when these assumptions are false, its power can be relatively low. Many new statistical methods have been proposed—ones that are aimed at achieving about the same amount of power when the assumptions of the F test are true but which have the potential of high power in situations where the F test performs poorly. A brief summary of some relevant issues and recent developments is provided. Some related issues are discussed and implications for future research are described. 相似文献
