Detection of Feigned Posttraumatic Stress Disorder: A Comparison of the MMPI-2 and PAI

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and Personality Assessment Inventory (PAI) were compared for detecting feigned posttraumatic stress disorder (PTSD) in a simulation research design. Participants were 85 undergraduates in one of three groups: PTSDs (n = 23), Fakers (n = 31), and Controls (n = 31). As expected, both the MMPI-2 and PAI discriminated PTSDs and Controls, with PTSDs scoring significantly higher on fake-bad validity scales and PTSD-relevant clinical scales. However, only the MMPI-2 discriminated Fakers and PTSDs, with Fakers scoring significantly higher on all MMPI-2 scales considered, but on only one PAI scale. Further, in logistic regression analyses the MMPI-2 demonstrated higher overall correct classification of PTSDs and Fakers than did the PAI. Although the MMPI-2 outperformed the PAI in detecting feigned PTSD, a substantial proportion of Fakers avoided detection by MMPI-2 fake-bad validity scales, suggesting that both tests are vulnerable to feigning of PTSD by motivated respondents with relatively limited coaching.     

Analysis of a two-alternative force-choice signal detection theory model

A basic problem in psychophysics is recovering the mean internal response and noise amplitude from sensory discrimination data. Since these components cannot be estimated independently, several indirect methods were suggested to resolve this issue. Here we analyze the two-alternative force-choice method (2AFC), using a signal detection theory approach, and show analytically that the 2AFC data are not always suitable for a reliable estimation of the mean internal responses and noise amplitudes. Specifically, we show that there is a subspace of internal parameters that are highly sensitive to sampling errors (singularities), which results in a large range of estimated parameters with a finite number of experimental trials. Four types of singular models were identified, including the models where the noise amplitude is independent of the stimulus intensity, a situation often encountered in visual contrast discrimination. Finally, we consider two ways to avoid singularities: (1) inserting external noise to the stimuli, and (2) using one-interval forced-choice scaling methods (such as the Thurstonian scaling method for successive intervals).     

如何导引"儒门道脉同归佛海"?——蕅益智旭对《论语》的解释

该文分析十七世纪蕅益智旭(1599-1677)对《论语》的思想世界的解释。该文首先指出,智旭以无限生命、死生一致的观点作为核心,重构孔门的生死观,再以心学之立场重新解释孔子思想中的“学”、“道”与“天命”三个重要概念。智旭将“学”解释为“心”之觉醒,将“道”理解为“空生大觉”之道,将“知天命”解释为对“不生不灭之理”与“虚妄生灭之原”的通透。凡此种种新诠,在东亚《论语》诠释史上,均有其特殊性,一方面展现王阳明以后以“心”学解释经典的“自由的”学风,另一方面则显示明末三教合一之思想趋向。     

医学生综合素质评价的科学性思考

对医学生综合素质的评价应建立发展性评价观,要充分体现六个统一:评价指标体系做到职业需要和社会发展相统一;评价功能做到全面性和发展性相统一;评价标准要做到综合化和个性化相统一;评价过程要做到结果与过程相统一;评价方法做到量化评价与质性评价相统一;评价主体要做到外部评价和内部评价相统一.使素质教育评价科学化,能真正促进医学生素质的全面发展,培养出合格的适合社会需要的医学人才.     

幼儿加减法运算中的策略发展特点

本研究随机选取北京市三所普通幼儿园小、中、大班儿童共90名,采用实物操作的非言语任务,考察3-5岁幼儿在加减法运算中的策略发展特点。结果表明:随着年龄的增长,儿童使用的策略由模仿、交换向内化、相反数策略转化;3、4岁幼儿在相反数题中,更多使用模仿和交换策略,而5岁幼儿更多使用模仿、相反数策略;在标准型题中,儿童一般较多使用模仿和内化策略;最大表征对儿童策略选择存在影响。     

儿童计算的元认知监测及其对策略选择的影响

为了考察儿童在计算中的元认知监测及其对策略选择的影响,选用两种实验材料,对五种元认知监测判断的特点及监测判断对策略选择的影响进行考察,发现:儿童的元认知监测判断等级值总体上具有较高的一致性,元认知监测判断大多与策略选择高度相关,具有较好的预测力,但受材料、指导语等因素影响,又呈现出复杂的关系。本研究从一个侧面证实了元认知监控的基本假说和元认知监测判断的状态说。     

初中生数学焦虑的调查及其调控研究

数学焦虑既是心理科学研究的对象,又与教育、教学,特别是学科教学密切相关。本文调查发现:部分初中生存在过度的数学焦虑,并且在年级、性别等维度上具有明显差异;教师的评价方式、课堂气氛、数学考试是形成数学焦虑的主要原因。运用三条教学策略的实验研究表明,数学焦虑是可以调控的,而且数学焦虑的缓解对学生数学成绩的提高有一定的促进作用。

从认知发展看思维和逻辑的基本类型

人类和个人对事物的认知发展过程可分为感性认知和理性认知两大阶段。思维即理性认知。思维按其意识和复杂性程度可分为直觉思维、形象思维、抽象思维和辩证思维四种基本类型。逻辑学是描述思维的产物即思想的形式结构与其规律的科学,也是为思维提供思维形式与其变形规则的模规范性科学。当代逻辑学按其产生和适用的主要思维领域不同,可分为准逻辑、形象逻辑、形式逻辑和辩证逻辑四种基本类型。     

On value and culture

Value stands for the significance of things, and concepts of value are ideas, opinions and attitudes about what kind of things are significant. Studies on the concept of value cannot be separated from culture. Every society has its own distinct culture and concept of value shared by its people. The relationship between concept of value and culture shows that the building of the concept of value must be based on culture. Developing culture, providing excellent products of culture and better humanitarian environment are the premise for people’s possession of the correct concept of value. __________ Translated from Hebei Xuekan 河北学刊 (Hebei Academic Journal), 2005 (1) by Dong Lihe
