个体完成系列回忆任务时错误类型发展的实验研究

本实验以小学一、三、五年级学生和大学生为被试,选择三种类型的汉字(普通字、形似字和同音字)为实验材料,要求被试完成系列回忆任务。结果发现：各组被试在完成系列回忆任务时,出现了四种错误,即遗漏错误、侵入错误、移动错误和重复错误。其中遗漏错误、侵入错误和移动错误随年级升高而降低;移动错误的相对比例最高,重复错误的相对比例最低。同时还发现同音字引起的错误率明显高于普通字和形似字。     

《齐风》的"和谐"美

和谐是礼的最高境界,温柔敦厚是《诗经》和谐美的集中体现。《齐风》的和谐美,在社会生活方面,表现为女子个性的自由张扬,男人气度的雍容豪放;在诗歌形式方面,表现为声韵节奏的和谐舒缓。而春秋时期,齐国泱泱的大国气象,正是《齐风》和谐美建构的社会基础。     

积极组织学术研究--当代组织管理学中的新运动

积极组织学术研究是管理学中的一项新运动,由密歇根大学商学院倡导建立的积极组织学术研究小组发起。主张发展积极的人类优势,复苏、振兴和激发组织活力,使组织兴旺发达,使其员工迈向成功。研究者将研究重点集中于在组织环境中培养积极的要素,并在研究中构建严谨、系统的理论基础,以期实现组织、员工及研究者的共同发展。     

顿悟式组块破解的时间进程：ERP研究

本研究旨在探讨顿悟式组块破解的信息加工机制及神经动态变化。被试完成汉字拆解任务,也即从一个源汉字中移动部件从而得到有效汉字。研究操纵部件之间在空间交错背景下的类别关系：同类（移动部件和剩余部件都是汉字）和异类（移动部件是笔画,剩余部件是汉字）。与此同时记录事件相关电位变化。结果显示,同类条件比异类条件引发了更大的N2波动和减小的LPC波动。早期的N2效应可能提示了组块破解过程中的识别困难,而晚期的LPC效应可能提示了组块破解过程中的知觉转换困难。     

Responsibility Attribution For Violence Against Women: A Study Of Chinese Public Service Professionals

This study examined how Chinese public service professionals attributed responsibility to victims and perpetrators of violence against women (VAW). A total of 2,308 Chinese public service professionals in Hong Kong completed questionnaires on attitudes toward women, VAW–related perceptions, and assignment of responsibility to actors in written VAW vignettes. Compared to agency professionals consisting of medical doctors, lawyers, and police officers, communal professionals consisting of psychologists, social workers, and nurses attributed a higher level of responsibility to VAW victims and perpetrators. For both professional groups, attitudes toward women and educational attainment were the most salient predictors of responsibility attribution to VAW victims and perpetrators. Perceived VAW effects on victims were also a robust predictor of responsibility attribution to perpetrators. With regard to group differences, gender was predictive of responsibility attribution for communal but not for agency professionals. Except for perpetrator responsibility attribution for agency professionals, age was also predictive of how professionals assigned responsibility to VAW victims and perpetrators.     

胆囊收缩素对脂多糖诱发的病态行为及外周细胞因子的影响

细胞因子在病态行为的产生中有重要的作用。八肽胆囊收缩素在前人研究中表明能够拮抗脂多糖在大鼠体内引起的细胞因子的分泌。实验目的：利用八肽胆囊收缩素的抗炎作用研究细胞因子在病态行为中的作用。实验方法：共分两个实验进行, 将大鼠分为控制组、免疫激活剂脂多糖组(200 μg/kg剂量, 腹腔注射)以及注射不同剂量的八肽胆囊收缩素的实验组(分别为20 μg/kg 、40 μg/kg 、80 μg/kg 和120 μg/kg剂量), 各实验组在注射脂多糖前半小时注射相应剂量的八肽胆囊收缩素, 药物注射两小时后进行行为实验 (糖水摄取量测验、旷场测验和高架十字迷宫测验), 然后对大鼠前炎性细胞因子包括白细胞介素-1β(IL-1β)、白细胞介素-6 (IL-6)、肿瘤坏死因子-α (TNF-α)及抗炎性细胞因子白细胞介素-10(IL-10)的血清浓度进行分析。实验结果：脂多糖诱发大鼠产生病态行为, 与控制组相比, 脂多糖组糖水摄取量降低, 旷场测验中活动性降低, 高架闭臂进入次数减少; 脂多糖诱导炎性细胞因子分泌增加, 与控制组相比, 脂多糖组前炎性细胞因子IL-1β、IL-6、TNF-α的分泌增加。在脂多糖注射前注射八肽胆囊收缩素能够抑制前炎性细胞因子IL-1β、IL-6、TNF-α的分泌, 但八肽胆囊收缩素未能改善免疫诱导的病态行为。结论：本实验结果表明仅改变外周的细胞因子浓度并不能完全改变动物的病态行为, 病态行为的产生可能与脑区的细胞因子有更大的联系。     

通过法则关系区分员工对组织的认同与反认同

员工对组织的认同与反认同有相关的心理机制(如员工对自尊的追求)与社会基础(如组织身分的多样性), 但它们是相互独立的两个构念。在个人建立自己的社会身分时, 认同体现了“求同”、而反认同则体现“存异”。基于理论分析所构建的法则关系中, 二者具有不同的前因变量和结果变量。对5家企业250名员工的问卷研究发现, 对组织认同的员工会更倾向于主动维护组织利益, 而对组织反认同的员工在工作中敷衍了事。嵌套的系列结构方程结果表明二者分离的模型对数据的拟合, 好于将二者合并的模型, 验证了这两个构念不同的基本论点。     

Controlling item exposure and test overlap on the fly in computerized adaptive testing

This paper proposes an on‐line version of the Sympson and Hetter procedure with test overlap control (SHT) that can provide item exposure control at both the item and test levels on the fly without iterative simulations. The on‐line procedure is similar to the SHT procedure in that exposure parameters are used for simultaneous control of item exposure rates and test overlap rate. The exposure parameters for the on‐line procedure, however, are updated sequentially on the fly, rather than through iterative simulations conducted prior to operational computerized adaptive tests (CATs). Unlike the SHT procedure, the on‐line version can control item exposure rate and test overlap rate without time‐consuming iterative simulations even when item pools or examinee populations have been changed. Moreover, the on‐line procedure was found to perform better than the SHT procedure in controlling item exposure and test overlap for examinees who take tests earlier. Compared with two other on‐line alternatives, this proposed on‐line method provided the best all‐around test security control. Thus, it would be an efficient procedure for controlling item exposure and test overlap in CATs.     

Dispositional resistance to change: measurement equivalence and the link to personal values across 17 nations

The concept of dispositional resistance to change has been introduced in a series of exploratory and confirmatory analyses through which the validity of the Resistance to Change (RTC) Scale has been established (S. Oreg, 2003). However, the vast majority of participants with whom the scale was validated were from the United States. The purpose of the present work was to examine the meaningfulness of the construct and the validity of the scale across nations. Measurement equivalence analyses of data from 17 countries, representing 13 languages and 4 continents, confirmed the cross-national validity of the scale. Equivalent patterns of relationships between personal values and RTC across samples extend the nomological net of the construct and provide further evidence that dispositional resistance to change holds equivalent meanings across nations.
