Different roles of shared and vertical leadership in promoting team creativity: Cultivating and synthesizing team members’ individual creativity

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.     

The longitudinal association between social status insecurity and relational aggression: Moderation effects of social cognition about relational aggression

Previous research has shown that adolescents’ insecurity about their social status is related to their use of relational aggression. However, little is known about how adolescents’ social cognition may moderate this association. Employing a mixed-method approach and a short-term longitudinal design, this study addresses this issue by examining the moderation effects of attribution and outcome expectancies regarding relational aggression on the associations between social status insecurity and relational aggression among 476 Chinese adolescents (238 girls). The main results showed that self-serving attributions and instrumental outcome expectancies strengthened the positive and longitudinal association between social status insecurity and self-reported relational aggression. The findings of this study enrich our knowledge about the social cognitive processes pertinent to peer status and relational aggression among adolescents.

Working memory and stroop interference: an individual differences investigation

We investigated the claim that individual differences in working-memory capacity reflect limitations on the ability to inhibit task-irrelevant information and/or to maintain activation in the face of distracting or interfering events. Specifically, we investigated whether high- and low-capacity individuals differed in their susceptibility to interference on the Stroop task and whether high-capacity individuals employed a strategy for minimizing Stroop interference. In Experiment 1, we found that high-capacity participants showed substantial interference when conflict trials were infrequent, but almost no interference when conflict trials were frequent. In contrast, low-capacity participants showed substantial interference irrespective of the proportion of conflict trials. In Experiment 2, we found that high-capacity participants experienced substantial negative priming, slow responses when the to-be-named color was the irrelevant word on the previous trial. We discuss these results and their implications for high-capacity individuals' ability to reduce Stroop interference in light of both inhibitory and noninhibitory accounts of negative priming.     

The representation of discourse in the two hemispheres: an individual differences investigation

Two experiments were conducted to investigate discourse representation in the two cerebral hemispheres as a function of reading skill. We used a lateralized visual-field procedure to compare left hemisphere (LH) and right hemisphere (RH) sensitivity to different discourse relations in readers with varying skill levels. In Experiment 1, we investigated two levels of discourse representation in memory: (a) the propositional representation and (b) the discourse model. We found that all readers were sensitive to propositional relations in the LH. In contrast, sensitivity to propositional relations in the RH increased as a function of reading skill. In addition, reading skill was positively related to topic relations in the LH, whereas it was negatively in the RH. In Experiment 2, we investigated propositional relations of different distances and again found that all readers were sensitive to propositional relations in the LH, whereas sensitivity to propositional relations in the RH was negatively related to reading skill. In general, reading skill appears to be associated with left-lateralized discourse representations.     

归纳推理中的属性中心性效应

通过三个实验研究了属性的中心性程度对归纳推理的影响,结果表明,在归纳推理中存在属性中心性效应,中心属性比其他属性（次中心属性、再次中心属性）更能影响归纳推理。但属性中心性效应的出现受到了前提对象和结论对象相似性程度的制约,当前提对象和结论对象的相似程度高时,中心属性比其他属性更能影响归纳推理;随着相似性水平的降低,中心属性的归纳推理力度越来越弱,而次中心属性、再次中心属性的归纳推理力度则会依次表现出越来越强的趋势,到最后当前提对象和结论对象的属性完全不相似时,最次中心属性的归纳推理力度达到最高水平,而中心属性的归纳推理力度则降低到最低水平。由于再次中心属性的归纳推理力度的最高水平没有显著高于随机水平,而中心属性的归纳推理力度的最低水平却显著低于随机水平,因此,研究者认为,在前提对象和结论对象完全不相似的情况下,被试将确信不能采用中心属性来进行归纳推理的力度判断,而采用猜测的方式选择了肯定可以排除的项目之外的其他项目,这体现了具有不确定的归纳推理活动的过程的典型特征     

家长式领导与组织公正感的关系

以428名企事业单位员工为调查对象,采用问卷法,探讨了家长式领导与组织公正感的关系,结果表明：（1）仁慈领导对组织公正感各维度有显著的积极影响;德行领导对组织公正感各维度有显著的积极影响;权威领导对领导公正有显著的消极影响;（2）在分配公正、程序公正上,德行与权威领导有显著负交互效应;在领导公正、领导解释上,仁慈与权威领导有显著负交互效应。最后,对研究的理论和实践意义作了探讨,并提出了未来的研究方向
