国外外群体同质性效应研究述评

外群体同质性是刻板印象研究的一个特例,它是指人们倾向于认为外群体成员比内群体成员具有更加固定、刻板的特征,成员间具有更多的相似性和更少的变异性。目前国外外群体同质性效应研究具有以下几个特点:研究对象更为广泛;测量方法多样化;注重对机制的探讨;关注中介变量。     

Prolonged subjective duration near the hands: Effects of hand proximity on temporal reproduction

Psychonomic Bulletin & Review - It has been reported that human visual perception and attention are altered when the hands are nearby. Previous studies indicate that placing hands near stimuli...     

A Bayesian Power Analysis Procedure Considering Uncertainty in Effect Size Estimates from a Meta-analysis

In conventional frequentist power analysis, one often uses an effect size estimate, treats it as if it were the true value, and ignores uncertainty in the effect size estimate for the analysis. The resulting sample sizes can vary dramatically depending on the chosen effect size value. To resolve the problem, we propose a hybrid Bayesian power analysis procedure that models uncertainty in the effect size estimates from a meta-analysis. We use observed effect sizes and prior distributions to obtain the posterior distribution of the effect size and model parameters. Then, we simulate effect sizes from the obtained posterior distribution. For each simulated effect size, we obtain a power value. With an estimated power distribution for a given sample size, we can estimate the probability of reaching a power level or higher and the expected power. With a range of planned sample sizes, we can generate a power assurance curve. Both the conventional frequentist and our Bayesian procedures were applied to conduct prospective power analyses for two meta-analysis examples (testing standardized mean differences in example 1 and Pearson's correlations in example 2). The advantages of our proposed procedure are demonstrated and discussed.     

Reevaluating the two-representation model of numerical magnitude processing

One debate in mathematical cognition centers on the single-representation model versus the two-representation model. Using an improved number Stroop paradigm (i.e., systematically manipulating physical size distance), in the present study we tested the predictions of the two models for number magnitude processing. The results supported the single-representation model and, more importantly, explained how a design problem (failure to manipulate physical size distance) and an analytical problem (failure to consider the interaction between congruity and task-irrelevant numerical distance) might have contributed to the evidence used to support the two-representation model. This study, therefore, can help settle the debate between the single-representation and two-representation models.     

Assessing team performance: Moderating roles of transactive memory,hypercompetition, and emotional regulation

This study proposes a model based on transactive memory theory to analyze team performance. In the proposed model, team performance is influenced by hypercompetition and emotional regulation directly and indirectly via the mediation of transactive memory and knowledge sharing. According to the model, the direct effect of knowledge sharing on team performance is moderated by both hypercompetition and emotional regulation. Empirical testing of this model, using team personnel in banking, insurance, and financing firms, confirmed the applicability of the transactive memory theory among these service firms’ work teams. Managerial implications and research limitations are discussed.     

Hope,social support,and depression among Hong Kong youth: personal and relational self-esteem as mediators

Previous studies have shown that depression is negatively associated with hope and social support. However, little research has been undertaken to investigate the theoretical mechanisms underlying the connections among hope, social support, and depression. This study examined how two types of self-esteem (personal and relational) would mediate the relationship of hope and social support to depression among 384 Hong Kong adolescents (age: 12–18 years; M = 14, SD = 1.19). Participants reported their levels of hope, social support, personal self-esteem, relational self-esteem, and depressive mood. Results of the path analysis showed that both personal and relational self-esteem mediated the associations of hope and social support with depression. Hope and social support were associated with higher levels of personal and relational self-esteem, which were in turn related to decreased levels of depression. Theoretical and practical implications are discussed.

青州城历史城市地理的初步研究——以广县城与广固城为研究重心

青州城市建成区一带,历史时期曾经先后存在四座城市,即广县城——广固城——东阳城或南阳城——满城。广县城,西汉时期既已存在,之所以产生于下圈村一带,关键在于其地地处高阜,不宜受到洪水侵袭,且南倚含水丰富的岩层,无缺水之虞。广固城建于魏晋十六国时期,因时逢乱世,地理上重军事防御的色彩明显。由临淄城而广固城,历史时期青齐地区实现了第一次中心城市的转移,就魏晋十六国乱世而言,这一城市选择行为是相当成功的。进而论之,代广固城而兴的东、南两阳城及清代的青州满城,之所以均大体不出今天青州市区的范围,与它们均接近青齐地区几何中心的地理位置关系极大。
