Longitudinal construct validity of Brief Symptom Inventory subscales in schizophrenia

Longitudinal validity of Brief Symptom Inventory subscales was examined in a sample (N = 318) with schizophrenia-related illness measured at baseline and every 6 months for 3 years. Nonlinear factor analysis of items was used to test graded response models (GRMs) for subscales in isolation. The models varied in their within-time and between-times parameter constraints, with the homogeneous model being the least constrained, followed by the 2-parameter GRM and 1-parameter GRM. Results show that 4 subscales (Interpersonal Sensitivity, Hostility, Paranoid Ideation, Psychoticism) were consistent with the 1-parameter GRM, and 5 subscales (Somatization, Obsessive-Compulsive, Depression, Anxiety, Phobic Anxiety) were consistent with the 2-parameter GRM. There is evidence that the 9 subscales may be validly used to study change in single constructs over time.     

公平敏感性研究述评

公平敏感性是基于对Adams公平理论的批评提出来的,反映的是人们在公平问题上的个体差异性。该文首先对公平敏感性概念的提出与修正进行了回顾,并介绍了公平敏感性的测量方法和分类标准;然后分析了公平敏感性对于结果变量的直接及调节效应,个人及社会文化因素对公平敏感性的影响,并介绍了公平敏感性的跨文化比较;最后指出该领域未来的研究应着重澄清对概念理解的差异,改进分类标准,加强对公平敏感性影响因素以及中国人公平敏感性的研究     

教师组织公民行为与学校效能的关系研究

采用自编教师组织公民行为问卷和我国台湾学者陈信君编制的学校效能问卷,对301名中小学教师进行问卷调查。结果表明：①高级职称教师的组织公民行为高于低级职称教师;②省一级学校教师的组织公民行为高于市一级学校教师,而市一级学校教师的组织公民行为高于区一级学校教师;③教师组织公民行为与学校效能之间存在着显著的正相关;④教师组织公民行为的学校认同、责任意识和利他行为因素对学校效能有着显著的预测作用。     

驾驶员视觉注意对危险识别的影响及作用机制

驾驶中, 有效的视觉注意模式是驾驶员搜索与识别潜在道路危险的先决条件。通过分析驾驶员视觉注意对危险识别的影响, 提出情境意识假设与心理负荷假设。情境意识假设认为, 情境意识的质量决定了驾驶员视觉注意模式的灵活性, 进而影响危险识别。心理负荷假设认为, 心理负荷水平提高, 驾驶员视觉注意趋于集中, 不利于危险识别。建议未来研究可以在比较不同驾驶员情境意识的认知兼容性, 应用汽车驾驶自动化技术降低心理负荷以及检测并区分情境意识与心理负荷的影响等方面加以深入。     

可操作性在物体表征中的作用

近10年来, 越来越多的研究表明, 对可操作物体的识别不仅依赖物体的视觉信息, 同时也依赖操作它的动作信息和知识, 即可操作性。来自行为实验、脑成像和脑损伤病人的研究都表明, 物体的可操作性在物体识别中会被激活, 并起着重要的作用。可操作性的研究不但重新解释了生物与非生物、名词与动词的分离现象, 而且对于研究物体表征, 以及视觉物体识别的神经通路有着重要的理论意义。     

分配制度公平对员工分配公平感的影响:中国组织情境下的实证研究*

西方组织公平领域的主流观点认为要想提高员工的分配公平感,应着力提高分配过程的公平性以及上下级互动的公平性,即程序公平和互动公平。本研究发现:在中国组织情境下,较之程序公平和互动公平(人际公平、信息公平),分配制度公平对员工分配公平感的解释力最强;在分配制度不公平的情境下,程序公平和人际公平才会影响分配公平感,仅仅起到亡羊补牢的作用。     

可修改答案的计算机化自适应测验的方法

与传统的纸笔测验(Paper And Pencil Based Test, P&P)相比计算机化自适应测验(Computerized Adaptive Testing, CAT)根据被试的作答反应自适应地选择题目, 它不仅缩短了测验长度, 还极大地提高了测验的准确性。然而, 目前绝大多数CAT不允许被试修改答案, 研究者主要担心修改答案会降低CAT的有效性。允许修改答案符合被试一贯的测验习惯, 修改之后的分数更能反映被试真实的水平, 从而能够进一步促进CAT在实际中的应用。现有的研究主要从三个方面提出了可修改答案CAT的控制方法：一是测验设计; 二是改进选题策略; 三是建构模型。未来的研究应进一步探讨这些方法之间的比较与结合, 以及对可修改答案认知诊断CAT (Cognitive Diagnostic CAT, CD-CAT)的研究。     

Putting Raters in Ratees’ Shoes: Perspective Taking and Assessment of Creative Products

This study reported 2 experiments that studied the effect of perspective taking on assessment of creative products by using human raters. Forty responses of 2 alternative uses tasks (AUTs) and 15 alien stories generated by 6th-grade students were used as assessment materials. Undergraduate students as the novice raters assessed the products under 3 experimental conditions: assessing without any information of the ratees, assessing only with age information of the ratees, and assessing with age information and taking the perspective of the ratees. Results of Experiment 1 showed significant differences in creativity ratings between group 1 and 2. But no significant difference was found between group 2 and 3. In Experiment 2, raters in group 1 used objective perception and raters in group 3 were asked to take the perspective for more time. Raters in group 3 assigned higher ratings than the other 2 groups but no difference was found between group 1 and 2. Overall, the results showed the effect of perspective taking on assessment of creative products. Possible mechanisms of the effect and implications for creativity assessment and creativity teaching practice were discussed.     

Aging and the perception of speed

Two experiments were conducted to explore the potential effects of aging upon the perception and discrimination of speed. In the first experiment, speed difference thresholds were obtained for younger and older observers for a variety of standard speeds ranging from slow to fast. The second experiment was designed to evaluate the observers' ability to discriminate differences in the speed of moving patterns in the presence of significant amounts of noise (the noise was manipulated by limiting the lifetimes of individual moving stimulus elements). The results of both experiments revealed a significant deterioration in the ability of the older observers to perceive or detect differences in speed. While the presence of noise was found to affect the observers' discrimination performance, it affected both younger and older observers' thresholds in a proportionally equivalent manner-the older observers were no more affected by noise than the younger observers.     

The utility of psychological testing in assessing emotional damages in personal injury litigation

Psychological testing and assessment instruments frequently play a small but important role when psychologists assist the courts as emotional damage experts in personal injury matters. However, examiners frequently, if sometimes inadvertently, mislead the court with test interpretations that are based on clinical rather than forensic populations and that fail to appreciate the lack of robustness of clinical measures in this forensic context. Whereas published computerized interpretations repeatedly remind experts that personality test results should only be used as a method to generate hypotheses about the examinee that are to be subjected to further investigation and consideration, experts all too often inform the courts of test interpretations as if the test results were measures of clinical constructs rather than plaintiffs' self-reports of symptoms.
