基于RSM对Q矩阵相同的无锚题测验的等值

传统锚题-非等组设计下的测验等值,等值要求的满足具有主观性,并且由于锚题失效或难以获得等因素的影响,则该方法的使用受到了限制。因此,本研究基于规则空间模型的Q矩阵理论,生成两个Q矩阵相同但无锚题的测验的共同受测者,使用共同组设计,利用同时性估计的方法对测验进行等值,并考虑了作答失误率和测验结构对等值稳定性的影响。结果表明:共同组设计同时估计方法的等值稳定性取得了优于或等于锚题-非等组同时估计方法;失误率的增大也会导致等值稳定性的下降;并且不同的测验结构也对等值稳定性产生了影响,其中直线型和收敛型结构稳定性较好,发散型和无结构型较差。     

净影慧远与嘉祥吉藏的判教思想及其意义

慧远以二藏、四宗、顿渐局来判释佛陀所说经教.吉藏则以二藏三法轮来判释佛教经教.二者的共同之处在于皆以二藏判教思想为旨归.慧远、吉藏的二藏判教思想,是对整个南北朝判教思想的总结,标志着南北朝佛教判教思想的成熟.     

A Survey of Management Educators’ Perceptions of Unethical Faculty Behavior

To help academic associations in management develop, refine, and implement a code of ethics, we conducted a survey of management educators’ perception of the ethicality of 142 specific behaviors in teaching, research, and service. The results of the survey could be used to inform ethics committees of these associations regarding the level of acceptability of such conduct. The potential value of our study for the Academy of Management or similar management associations lie in our (1) systematically involving the members in building support for the code of ethics, (2) assessing members’ ethical judgments on both cross-sectional and longitudinal bases so as to identify areas needing particular attention in ethical training, (3) providing an extensive list of specific examples of questionable and potentially unethical behaviors so as to make it easier to implement the code, and (4) providing a template survey document for potential use in involving more stakeholder groups in the development of codes of ethics.

成就目标定向、测验焦虑与工作记忆的关系

在工作记忆广度测验情境下,以152名中学生为被试,考察成就目标定向、测验焦虑和工作记忆的关系。结果表明四种成就目标定向与测验焦虑和工作记忆间具有不同的关系模式：成绩-接近目标与较低的测验焦虑水平和较高的工作记忆广度相关;掌握-接近目标与担忧、情绪化,与工作记忆广度相关不显著;成绩-回避目标与测验焦虑中的担忧和情绪化正相关,与工作记忆广度负相关;掌握-回避目标与担忧和情绪化存在正相关,与工作记忆广度存在接近显著的相关。测验焦虑是成绩-接近和成绩-回避目标影响工作记忆的中介变量。在测验焦虑中,情绪化对工作记忆的干扰大于担忧的干扰     

视知觉学习的认知与神经机制研究

知觉学习是指由于训练或经验而引起的长期稳定的知觉变化,是一种内隐性的学习。近20年来,视知觉学习的大量研究结果提示大脑皮层的各个区域,甚至包括初级感觉皮层,在成熟之后仍然具有一定的可塑性。该文根据近年来的研究进展,对视知觉学习在大脑的什么地方,什么时候,以何种方式发生等热点问题进行了探讨。研究提示,视知觉学习涉及了包括初级视皮层在内的多个大脑皮层,并且存在一种自上而下的调控机制;视知觉学习可以在不同的时间尺度上发生,快速学习之后将伴随着慢速学习;通过视知觉学习,人们对于复杂物体的表征将从高级皮层区域移向低级皮层区域,任务执行也将趋于自动化     

句法加工的脑机制

语言理解中,句法加工至关重要,它把各个意义单元以不同的方式整合起来,从而形成整体的意义表征。句法加工的脑机制是心理语言学比较关注的问题,目前由于ERP技术和功能成像技术的进步,使对这一机制的探讨成为可能。该文对有关句法加工的脑机制的研究进行了回顾与总结,并针对目前该领域存在的问题与争论进行了讨论     

The psychophysics of chasing: A case study in the perception of animacy

Psychologists have long been captivated by the perception of animacy – the fact that even simple moving shapes may appear to engage in animate, intentional, and goal-directed movements. Here we report several new types of studies of a particularly salient form of perceived animacy: chasing, in which one shape (the ‘wolf’) pursues another shape (‘the sheep’). We first demonstrate two new cues to perceived chasing – chasing subtlety (the degree to which the wolf deviates from perfectly ‘heat-seeking’ pursuit) and directionality (whether and how the shapes ‘face’ each other). We then use these cues to show how it is possible to assess the objective accuracy of such percepts, and to distinguish the immediate perception of chasing from those more subtle (but nevertheless real) types of ‘stalking’ that cannot be readily perceived. We also report several methodological advances. Previous studies of the perception of animacy have faced two major challenges: (a) it is difficult to measure perceived animacy with quantitative precision; and (b) task demands make it difficult to distinguish perception from higher-level inferences about animacy. We show how these challenges can be met, at least in our case study of perceived chasing, via tasks based on dynamic visual search (the Find-the-Chase task) and a new type of interactive display (the Don’t-Get-Caught! task).     

Young children's affective decision-making in a gambling task: Does difficulty in learning the gain/loss schedule matter?

This research investigated the development of affective decision-making (ADM) during early childhood, in particular role of difficulty in learning a gain/loss schedule. In Experiment 1, we administrated the Children's Gambling Task (CGT) to 60 Chinese children aged 3 and 4, replicating the results obtained by Kerr and Zelazo [Kerr, A., & Zelazo, P. D. (2004). Development of “hot” executive function: The Children's Gambling Task. Brain and Cognition, 55, 148–157]. In Experiment 2, the CGT was modified to make it easier for young children to learn the gain/loss schedule by increasing delayed loss frequency and magnitude in the disadvantageous deck, and a larger sample (181 children aged 3–5) was assessed. Age-differences between 3- and 4-year-olds, rather than 4- and 5-year-olds, showed that ADM develops rapidly between 3 and 4 years. The reduction of the difficulty in learning the gain/loss schedule provides the basis for an account of the development of young children's AMD.     

内疚和羞耻的关系——来自反事实思维的验证

运用情境模拟法从反事实思维的角度探讨内疚与羞耻的关系.并比较了大学生和青少年罪犯反事实思维与内疚和羞耻关系方面的特点.结果表明:(1)研究结果部分支持"内疚事件和羞耻事件"假设,但不支持Lewis提出的"自我和行为"假设,甚至与该假设相反;(2)大学生和青少年罪犯反事实思维与内疚和羞耻的关系具有某些方面的一致性.但也存在着很大的差异.大学生自我导向的反事实思维与内疚感有更为密切的联系,而青少年罪犯行为导向的反事实思维与羞耻感有更为密切的联系.
