题目难度分布和样本容量对两种CTT等值结果的影响

基于经典测验理论(CTT)的等值方法主要有线性等值和等百分位等值两种。在不同情境下,不同的等值方法会产生不同的等值结果。本研究以真分数等值为依据,用蒙特卡洛模拟研究方法,综合比较了各种题目难度分布条件下和各种样本容量条件下两种CTT等值方法的等值结果。研究结果表明:(1)线性等值的误差受题目难度分布影响较大,等百分位等值的误差几乎不受题目难度分布影响。(2)线性等值的误差几乎不受样本容量的影响,等百分位等值的误差受样本容量影响较大。(3)不论题目难度分布如何,只要样本容量足够大,等百分位等值的效果都比线性等值更好。     

数学问题类比迁移的影响因素研究

类比迁移在人类的学习中有着不可替代的地位,但学科问题类比迁移的相关研究仍不充足。本文以数学问题解决为研究对象,探讨了数学问题类比迁移的影响因素。实验研究了问题相似性、被试特点(年级、元认知监控)对数学问题类比迁移的影响。实验结果表明:源靶问题间的表面相似性是影响类比迁移的主要因素,它既促进正迁移,也容易导致负迁移;不同年级被试解决数学问题成绩差异显著;被试在解决数学问题时的实时元认知监控与该问题的解决相关显著。

Reliability coefficients for multiple group item response theory models

Reliability of scores from psychological or educational assessments provides important information regarding the precision of measurement. The reliability of scores is however population dependent and may vary across groups. In item response theory, this population dependence can be attributed to differential item functioning or to differences in the latent distributions between groups and needs to be accounted for when estimating the reliability of scores for different groups. Here, we introduce group-specific and overall reliability coefficients for sum scores and maximum likelihood ability estimates defined by a multiple group item response theory model. We derive confidence intervals using asymptotic theory and evaluate the empirical properties of estimators and the confidence intervals in a simulation study. The results show that the estimators are largely unbiased and that the confidence intervals are accurate with moderately large sample sizes. We exemplify the approach with the Montreal Cognitive Assessment (MoCA) in two groups defined by education level and give recommendations for applied work.

计算机自适应测验在特质焦虑量表中的运用

将基于项目反应理论的计算机自适应测验运用于特质焦虑量表,考察这一测验形式在人格测量中所具有的特性.收集特质焦虑量表真实纸笔作答数据,选用合适的心理测量模型,模拟计算机自适应测验.结果表明：相对纸笔测验而言,计算机自适应测验的测试效率更高、对被试的分辨力更强、结果更直观.计算机自适应测验在人格测量中的实践值得进一步探索.     

记忆汉字和英语单词的差异脑区研究

通过英文词和汉字的记忆实验,探讨储存和提取不同阶段汉字与英文的脑加工差异。采用经典的"学习-再认"实验范式,8名大学生进行英文与汉字记忆和再认测验,fMRI采集数据,AFNI软件进行预处理、多元回归及ANOVA组分析统计语言差异。结果显示:汉字记忆减英文记忆激活右扣带回;英文记忆减汉字记忆激活右颞上回(BA38)、左扣带回(BA31)、左小脑扁桃体。汉字再认减英文再认的差异脑区为小脑扁桃体、左颞上回。英文再认减汉字再认在0.05水平上没有脑区差异。汉字记忆激活左侧梭状回、右舌回、左顶上小叶、左额下回;英文记忆激活右舌回、左内侧前额叶、左中央前回、左额中回。汉字再认激活左枕下回、左顶下小叶、右额下回、左额中回、右豆状核、左小脑扁桃体、左颞上回、右内侧前额叶。英文再认激活右舌回、左额上回、左顶下小叶、额下回、左中央前回、右顶上小叶、豆状核、右侧尾状核、左中央后回、左侧丘脑。本研究发现:(1)记忆的差异性统计激活颞叶,表明颞叶是记忆存储脑区;(2)学习和记忆阶段有额叶、顶叶激活,表明这些脑区参与文字加工;(3)英文再认比汉字再认激活更多脑区,花费更多的脑资源。     

The Order of Pascal's Politics

This essay rejects two common views of Pascal: (a) that he holds only temporal and contingent standards of justice to be available to human beings and (b) that he is indifferent to all but eternal standards of justice. Against these reductive misunderstandings, I provide a detailed reconstruction of Pascal's political thought, drawn from the Pensées and other texts. I show that Pascal develops an account of two distinct and hierarchized orders of justice: a temporal order and an eternal order. Pascal recognizes the integrity of the temporal order of justice, as expressed in local, particular custom and the historical development of positive law and, at the same time, holds that the axiological and ontological condition of this temporal order is an eternal order, a horizon beyond history which serves to ground it. Pascal's politics, rather than a tragic pessimism or a passion for the absolute, is simply a limited specification of his moral and metaphysical realism.     

Validating a New Measure of Self-Complexity

The construct of self-complexity has been recognized as important for understanding psychological adjustment. However, research in this area has been impeded by measurement problems. In particular, the most commonly used measure, Linville's (1985, 1987) H statistic, cannot assess this construct appropriately. In this article, we present a new measure designed to tap two components of self-complexity separately: the number of self-aspects and the average distinction among them. We conducted a validation study with 131 Chinese college students. The results indicate that (a) this new measure is not confounded with conscious social desirability bias, (b) it has incremental validity beyond existing measures, and (c) the two components as assessed by this new measure are relatively independent and have different psychological functions. We discuss the implications of these findings for future studies of self-complexity and clinical practice.
