Special Topic: Filial Piety: The Root of Morality or the Source of Corruption?

In recent years, Liu Qingping 劉清平 has published a series of articles criticizing Confucian ethics in its modern context (see various articles by Liu), which has drawn the attention of many scholars. My friends and I have debated with him and his allies on this issue (See Guo 2002, Yang Haiwen 2002, Yang Zebo 2003, 2004a, 2004b, Ding 2003, 2005a, 2005b, Gong 2004, Guo and Gong 2004, and Wen 2005). Most of the important articles in the debate are now collected in a volume I edited, A Collection of Contentions about Confucian Ethics: Focusing on the Mutual Concealment among Family Members (Guo 2005 [ed.]). In the following, I attempt to respond to some of Liu’s criticisms of Confucian ethics.     

考试自我效能感是考试焦虑影响考试成绩的中介变量

本文采用结构方程的统计分析技术．依据Baron(1986)提出的确定中介变量的规则和标准．对265名中学生的特质考试焦虑、考试自我效能感、数学期末考试成绩的关系进行了探讨。考试焦虑,考试自我效能感和数学考试成绩是三个潜变量。结果表明,考试焦虑通过考试自我效能感这一中介变量对考试成绩产生影响,考试自我效能感对考试成绩有直接的影响作用,是考试焦虑影响考试成绩的中介变量。     

时-空整合影响图形识别的眼动研究

采用眼动追踪的方法对在不同方向(上、下、左与右)及距离(2.0°‘和4.0°视角)上先后出现的特征组合不同的图形识别过程进行了研究。结果表明。首先,对由不同颜色和形状构成的图形的识别受到图形特征组合的影响,视觉系统对颜色和形状的加工存在明显差异,与颜色加工相比,视觉系统需要更多的时间才能完成形状识别。此外,虽然图形识别的速度和准确性受运动方向与距离的影响较小,但在不同运动方向和距离上,视觉系统是通过改变眼动的时间和空间特性来完成识别任务的,视觉系统在识别过程中的这种时间与空间的整合特点还有待于进一步研究。     

Sample size planning with the cost constraint for testing superiority and equivalence of two independent groups

The allocation of sufficient participants into different experimental groups for various research purposes under given constraints is an important practical problem faced by researchers. We address the problem of sample size determination between two independent groups for unequal and/or unknown variances when both the power and the differential cost are taken into consideration. We apply the well‐known Welch approximate test to derive various sample size allocation ratios by minimizing the total cost or, equivalently, maximizing the statistical power. Two types of hypotheses including superiority/non‐inferiority and equivalence of two means are each considered in the process of sample size planning. A simulation study is carried out and the proposed method is validated in terms of Type I error rate and statistical power. As a result, the simulation study reveals that the proposed sample size formulas are very satisfactory under various variances and sample size allocation ratios. Finally, a flowchart, tables, and figures of several sample size allocations are presented for practical reference.     

“物质无限可分”是全称存在命题

运用分析哲学方法研究物质可分性问题,能够得到这样的结果:"物质无限可分"是全称存在命题;"物质有限可分"是存在非存在命题。而这两个命题都既不可证实又不可证伪。因此,"物质结构是否无限可分"是一个超经验的信仰问题,无法从经验上证明究竟是肯定回答正确,还是否定回答正确,因而这方面的争论没有什么意义。     

Accumulative Equating Error after a Chain of Linear Equatings

After many equatings have been conducted in a testing program, equating errors can accumulate to a degree that is not negligible compared to the standard error of measurement. In this paper, the author investigates the asymptotic accumulative standard error of equating (ASEE) for linear equating methods, including chained linear, Tucker, and Levine, under the nonequivalent groups with anchor test (NEAT) design. A recursive formula for the ASEE is provided for a series of equatings that makes use of only historical summary statistics. This formula can serve as a new tool to measure the magnitude of equating errors that have accumulated over a series of equatings, and to help monitor and design testing programs.     

一种多级评分的广义认知诊断模型

认知诊断是近些年教育测量研究中的热点,大多数的认知诊断模型仅适用于0～1评分的情况.本文提出一种有多个潜变量多个滑动参数的多级评分认知诊断模型——GP-D1NA,只要由评分标准和知识状态能确定理想反应模式,就可以利用此方法进行认知诊断分析.在该方法中,我们给出项目滑动矩阵的概念,将被试的观测得分均看成由某个理想得分的滑动,并采用EM算法估计滑动矩阵.在模拟研究中,采用每掌握一个属性得1分的评分标准,结果表明线性型、收敛型、发散型、无结构型和独立型五种属性层级结构均有较高的判准率.     

Learning without consciously knowing: Evidence from event-related potentials in sequence learning

This paper investigated how implicit and explicit knowledge is reflected in event-related potentials (ERPs) in sequence learning. ERPs were recorded during a serial reaction time task. The results showed that there were greater RT benefits for standard compared with deviant stimuli later than early on, indicating sequence learning. After training, more standard triplets were generated under inclusion than exclusion tests and more standard triplets under exclusion than chance level, indicating that participants acquired both explicit and implicit knowledge. However, deviant targets elicited enhanced N2 and P3 components for targets with explicit knowledge but a larger N2 effect for targets with implicit knowledge, revealing that implicit knowledge expresses itself in relatively early components (N2) and explicit knowledge in additional P3 components. The results help resolve current debate about the neural substrates supporting implicit and explicit learning.     

元认知与学习动机关系的研究

对于元认知与学习动机之间的关系,已有研究采用相关分析、回归分析的方法进行了初步探讨,但无论是相关还是回归都不能使我们清楚地了解两者之间的相互作用。本研究的目的即是运用路径分析的方法对这一问题进行较为深入的探讨。路径分析表明,动机变量对元认知活动具有“供能”的作用;动机变量对元认知的影响有的是直接发生的,如考试焦虑、目标定向,有的则是以其它变量为中介而间接发生的,如动机强度、学业自我概念。     

自我:从生物性到精神性

本文一方面从“生物性”与“精神性”两个人性层次透视自我,将自我视为一个由“生物自我”与“精神自我”组成的、以“生物自我”为基础“精神自我”为目标的对立统一体;另一方面又从“内容”与“功能”两个意识维度解析自我,将自我看成既是一个意义的存在又是一架认识的“机器”。自我便是一个由上述两个层次与维度有机组成的心理系统,这里的“有机”的涵义主要体现在,不仅生物自我与精神自我是相辅相成的辩证结构,而且这两个层次又都各自表现为内容与功能相互联系的认识主体。
