Social class demarcates sociocultural environments differing in the relative abundance and scarcity of resources, which in turn differentially afford independent and interdependent psychological processes. The relationships between social class and psychological processes are well documented in Western populations but less so elsewhere. Examining such a relationship is particularly important in China, with its unique historical and sociocultural issues surrounding social class. This research examined the relationship between social class and independence–interdependence among Chinese adolescents (N = 1184). Findings were consistent across a diverse array of psychological processes implicated by independence–interdependence: Participants with well‐educated parents experienced more socially disengaging emotions and a higher level of self‐esteem, and were more inclined toward dispositional attribution and focused attention, compared to participants with less well‐educated parents. These findings highlight the cross‐cultural commonality in the relationship between social class and independence–interdependence. 相似文献

The present study examined the spatial distribution of involuntary attentional capture over the two visual hemi-fields. A new experiment, and an analysis of three previous experiments showed that distractors in the left visual field that matched a sought-for target in color produced a much larger capture effect than identical distractors in the right visual field, revealing a visual field asymmetry in color-based contingent capture. On the other hand, abrupt onsets in the two hemi-fields did not differ in the magnitude of their capture effect, indicating a symmetric distribution of onset capture. The different spatial patterns for contingent capture and onset capture reveal differences between the two types of attentional capture, possibly indicating differences in the underlying brain mechanisms. 相似文献

垄断企业高管薪酬:不足还是过度? 总被引:1,自引:0,他引:1
垄断的"放大效应"使垄断企业业绩对高管努力的敏感度大干非垄断企业业绩对高管努力的敏感度.本文用模型证明了,当高管能力相同、努力程度相同时,资产规模相同的垄断企业的业绩大干非垄断企业的业绩,主要是因为垄断企业天生被赋予的垄断优势.因此,当垄断企业和非垄断企业业绩相同时,支付给垄断企业高管的薪酬应该低于支付给非垄断企业高管的薪酬.论文还用2008年上市公司的数据验证了垄断的"放大效应",检验了当前垄断企业高管薪酬水平的合理性,最终发现目前垄断企业的高管薪酬相对于其业绩来说是过高的,存在激励过度问题. 相似文献

AbstractLiterature addressing missing data handling for random coefficient models is particularly scant, and the few studies to date have focused on the fully conditional specification framework and “reverse random coefficient” imputation. Although it has not received much attention in the literature, a joint modeling strategy that uses random within-cluster covariance matrices to preserve cluster-specific associations is a promising alternative for random coefficient analyses. This study is apparently the first to directly compare these procedures. Analytic results suggest that both imputation procedures can introduce bias-inducing incompatibilities with a random coefficient analysis model. Problems with fully conditional specification result from an incorrect distributional assumption, whereas joint imputation uses an underparameterized model that assumes uncorrelated intercepts and slopes. Monte Carlo simulations suggest that biases from these issues are tolerable if the missing data rate is 10% or lower and the sample is composed of at least 30 clusters with 15 observations per group. Furthermore, fully conditional specification tends to be superior with intraclass correlations that are typical of crosssectional data (e.g., ICC?=?.10), whereas the joint model is preferable with high values typical of longitudinal designs (e.g., ICC?=?.50). 相似文献

CLARION是一个与其它认知理论明显不同的计算认知模型,它可用来研究内隐和外显学习交互作用的各种定量数据。通过对经典内隐学习任务(如系列反应时任务、加工控制任务及其他高级认知加工任务)的模拟实验,在与人类实验数据的拟合上,CLARION展示出比以往认知模型更好的性能。它主要有两个特征:一是对内隐学习和外显学习的整合,二是对自下而上加工的强调。近几年,CLARION模型在理论和实践上都有较大进展。文章简要评述了CLARION模型,并围绕此模型介绍了学界有关内隐和外显加工交互作用的探索 相似文献

本研究通过两个实验来比较源记忆和靶记忆的难度。实验一比较两种记忆提取阶段的事件相关电位(ERPs)。实验二设置较高的成功标准,比较两者达标所需的时间,以此比较它们的难度。在实验一中,被试先进行项目记忆任务,接着进行源记忆任务(从两位虚拟人处接收项目,并记住项目的来源)和靶记忆任务(向两位虚拟人递送项目,并记住项目的去向)。源记忆和靶记忆的测试阶段要求被试再认项目的源或靶,并记录提取阶段的脑电。结果显示,虽然源记忆与靶记忆的正确率没有显著差异,但是在正确提取的ERP中观察到,两者与回想有关的LPC之间有边缘显著差异(靶记忆比源记忆更趋正向,且在顶区差异最明显),这说明在回想上,靶记忆可能比源记忆需要更深的加工。实验二将源记忆和靶记忆结合在同一个任务中,要求被试反复尝试,直至两种记忆的正确率都达到较高的成功标准(近90%)。结果进一步证实,源记忆的加工水平深于源记忆。 相似文献
