团队异质性的平衡性对团队创造力的影响

团队异质性的平衡性是指团队中异质性属性的相对分布情况, 是一个从不平衡到平衡的连续谱概念。作为对团队构成维度的补充, 本研究探究其如何通过团队信息深化施加影响于团队创造力。通过对浙江理工大学451名学生的团队实验研究, 得出结论认为：团队知识异质性的平衡性能够积极影响团队创造力, 且团队信息深化在这一过程中起中介作用, 性别异质性的平衡性与团队创造力之间的关系不显著。这一研究结果将有助于打开团队构成和团队创造力研究的新局面。     

Conceptual elaboration versus direct lexical access in WAIS-similarities: differential effects of white-matter lesions and gray matter volumes

Wechsler Adult Intelligence Scale (WAIS) subscale Similarities have been classified as a test of either verbal comprehension or of inductive reasoning. The reason may be that items divide into two categories. We tested the hypothesis of heterogeneity of items in WAIS-Similarities. Consecutive patients at a memory clinic and healthy controls participated in the study. White-matter hyperintensities (WMHs) and normalized temporal lobe volumes were measured based on Magnetic resonance Imaging (MRI), and tests of verbal memory and attention were used in addition to WAIS-Similarities to collect behavioural data. Factor analysis supported the hypothesis that two factors are involved in the performance of WAIS-similarities: (1) semiautomatic lexical access and (2) conceptual elaboration. These factors were highly correlated but provided discriminative diagnostic information: In logistic regression analyses, scores of the lexical access factor and of the conceptual elaboration factor discriminated patients with mild cognitive impairment from Alzheimer’s disease patients and from healthy controls, respectively. High scores of WMH, indicating periventricular white-matter lesions, predicted factor scores of direct lexical access but not those of conceptual elaboration, which were predicted only by medial and lateral temporal lobe volumes.     

Changing prejudiced attitudes,promoting egalitarianism,and enhancing diversity through fundamental processes of persuasion

ABSTRACT

We review work from persuasion science relevant to reducing prejudiced attitudes. We begin by introducing the idea that the thoughts people generate – their number and valence – are critical for understanding when responding to persuasive attempts will result in egalitarian attitudes. A focus on thinking highlights the importance of understanding short and long-term attitude change in promoting diversity. How much people think is also consequential for spreading of initial change to more distal attitudes and generalization of change to other judgments. The second section describes a process of thought validation that emphasizes the importance of considering what people think and feel about their own thoughts. This meta-cognitive process is shown to make a difference in producing consequential changes in reducing prejudiced attitudes toward African Americans, immigrants, refugees, individuals with disabilities, and beyond. The conditions under which variables such as minority status and stigmatized sources affect elaboration and validation are also specified. The fourth section explores how these two processes are relevant for understanding explicit and implicit ambivalence and change in the domain of prejudiced attitudes. We highlight the utility of a process-oriented approach for designing future research and promoting more inclusive attitudes and actions.
