轻微及中度抑郁者的积极自我

研究基于积极心理视角,考察抑郁个体在多个自我维度上,外显及内隐自尊的水平高低与稳定特性。被试选自高中学生,有效数据131人,分为抑郁(65人)与正常(66人)两组。所有被试在有/无应激两个时间点完成自我描述问卷II与改进内隐联想测验。结果发现,不论外显/内隐水平,抑郁个体倾向在指向个体内部的自我维度上具有积极自我,并且倾向在核心价值之外的自我维度上具有稳定自尊。由此证实,抑郁个体自我机制中的确存在积极成分。     

来源记忆提取的情境线索效应

探索当存在多维来源信息时,对一个维度的来源信息的再现是否会促进对另一个维度的来源记忆的提取,即出现情境线索效应。以汉字词语作为项目刺激,以背景颜色作为情境线索,通过两个实验分别考察对呈现位置和背景形状的提取是否会出现情境线索效应。结果发现：只在对背景形状的提取中出现了情境线索效应,并且线索负载越高,效应越小。该结果表明对来源记忆提取时,来源信息间的高可结合性是引发情境线索效应的重要因素。     

双因子模型：多维构念测量的新视角

双因子模型是一种既有全局因子又有局部因子的模型,近年来有了许多应用。本文讨论了双因子模型和高阶因子模型在数学模型、参数之间的关系,概念上和应用上的差异;概述了双因子模型在信度研究、平衡量表、探索性因子分析和项目反应理论中的应用。作为例子,在Rosenberg自尊量表结构的研究中,通过双因子模型分析了自尊特质效应与项目表述方法效应。     

A sufficient condition for pooling data

We consider the problems arising from using sequences of experiments to discover the causal structure among a set of variables, none of whom are known ahead of time to be an “outcome”. In particular, we present various approaches to resolve conflicts in the experimental results arising from sampling variability in the experiments. We provide a sufficient condition that allows for pooling of data from experiments with different joint distributions over the variables. Satisfaction of the condition allows for an independence test with greater sample size that may resolve some of the conflicts in the experimental results. The pooling condition has its own problems, but should—due to its generality—be informative to techniques for meta-analysis.     

临床方法依然是神经内科医师最重要的诊断法宝

通过7例疑难、危重患者的诊治过程说明临床方法的重要性,在神经科疾病研究中尤为突出。忽视细致的病史采集和体查,常导致了诊疗的失误;面对种目繁多的检查,更需要以临床方法选择之;临床逻辑思维能力非常重要,正确的临床思维出新知。在实验室检查方法越来越多的今天,临床方法是神经内科医师最重要、方便、快捷、有效的诊断法宝,具有不可替代性。     

Conscious and unconscious forms of memory in different implicit tests

This study investigated how shallow processing (complexity rating), deep processing (pleasantness rating), and semantic generation (translating from English) of Chinese words affects conscious memory (CM) and unconscious memory (UM) of the words with three implicit tests: word association, word identification, and word-stem completion. A metacognition-based dissociation procedure was used to estimate the two forms of memory for each test. Except for the shallow condition preceding the word-association test, all three study conditions produced a positive effect on the estimate of CM. The estimate of UM did not benefit from any of the study conditions in the word-association test, it benefited from the shallow and deep conditions but did not benefit from the generation condition in the stem-completion test, and it benefited from the shallow condition but did not benefit from the deep and generation conditions in the word-identification test. Implications of these results for CM and UM operations are discussed.     

多维项目反应理论：参数估计及其在心理测验中的应用

本研究介绍并引进了现代测量理论中的前沿技术—— 多维项目反应理论, 采用MCMC算法实现了其参数估计; 并将MIRT应用于瑞文高级推理测验, 以探讨MIRT在心理测验中的具体应用。研究结果表明：(1)本研究自主编制的MIRT参数估计程序基本可行, 其估计的精度与国外研究结论相当甚至更好。(2)在测验维度和样本容量两因素完全随机实验设计下(2×3), 随着被试和题目样本容量的增加, MIRT参数估计的精度越高且估计的稳定性越强; 但随着测验维度的增加, MIRT参数估计精度和稳定性均随之降低。(3)MIRT对心理测验的分析比UIRT能提供更为精确和细致的信息。它对心理测验的编制、开发及评价具有重要的指导和参考价值, 值得引进及借鉴。     

学前儿童的现实性监测:即时和延时测验

考察了4至5岁儿童的现实性监测在延时0天、3天和7天条件下的成绩。结果发现:对真实动作的源混淆更多地发生在延时3-7天,而对想象动作的源混淆更多地发生在0-3天,且对想象动作的现实性监测比对真实动作的现实性监测更早达到随机水平。这表明事件在现实性监测的时间效应中存在不同的特点。     

Practical Limitations in Making Decisions Regarding the Distribution of Applicant Personality Test Scores Based on Incumbent Data

For practitioners, the possibility of faking on personality tests has potential implications that are much broader than those captured by current theoretical debates over criterion-related validity, factor structure, or psychological processes. One unexplored potential impact of response distortion involves the pass rates associated with applying cutoff scores developed using a concurrent validation design to applicant samples. This practitioner-oriented paper compared applicant and incumbent scores on three personality dimensions and uncovered significant standardized group differences. These differences greatly influenced pass rates for three different selection models, which impacted expected utility of the selection system. Potential solutions for practitioners are provided, along with recommendations for future research in this area. An earlier version of this paper was presented at the annual meeting of the Society for Industrial and Organizational Psychologists in Orlando, Florida.
