IRT与MIRT在测验垂直等值中的应用

测验垂直等值是指将测试同一心理特质的不同水平的测验转换到同一个分数量尺上的过程。IRT与MIRT是实现垂直等值的主要方法。IRT无需假设被试的能力分布, 参数估计不依赖于样本, 是构建垂直量表的有效方法, 但测验不满足单维假设时其应用受到限制。MIRT结合IRT和因素分析的特点对IRT进行了拓展, 可更有效估计多维测验的项目参数和被试能力参数, 在垂直等值中有重要应用。已有研究主要探讨IRT和MIRT在垂直等值应用中的适用性、标定方法和参数估计方法, 比较研究两种方法的特性。未来研究应纳入更多变量条件进行比较研究, 拓展方法的应用。     

小学生学习坚持性和学习投入在效能感、内在价值与学业成就关系中的中介作用*

采用学习坚持性问卷、自我效能感问卷、内在价值问卷和学习投入量表,对407名四、五年级小学生施测,并收集学生期中考试成绩作为客观指标,建立结构方程模型以考察学习坚持性和学习投入在自我效能感、内在价值与学业成就关系中的中介作用。结果发现:(1)学习坚持性与自我效能感、内在价值、学习投入、学业成就均显著正相关;(2)学习坚持性可以部分中介自我效能感与学习投入、内在价值与学习投入之间的相关;(3)学习坚持性通过学习投入的中介作用影响学业成就。     

The Effectiveness and Trustworthiness of Faith-Based and Other Service Organizations: A Study of Recipients' Perceptions

Drawing on a new community study of more than 2,000 residents of low-income neighborhoods, we examine information about the kinds of service organizations respondents have contacted for assistance and the perceptions of these respondents about the effectiveness and trustworthiness of those organizations. We compare contact with and perceptions of faith-based organizations, nonsectarian organizations, government agencies, hospitals, and churches and employ a method that takes account of respondents' varying portfolios of service providers. The results indicate that the recipients of faith-based organizations resemble those of the public welfare department in the extent of financial need and scope of family problems, and differ significantly from recipients of help from congregations. The results also indicate that recipients' evaluations of the effectiveness and trustworthiness of their portfolio of service organizations are lower when they have sought assistance from public welfare agencies and higher when they have sought assistance from congregations, but are not significantly affected by having contacted faith-based or nonsectarian organizations.     

注意定势对基于空间位置的返回抑制的影响

将研究注意定势的比例控制范式与基于空间位置的返回抑制范式相结合。系统地探讨了与空间位置相关的注意定势对基于空间位置的返回抑制的影响。结果表明。在20％和50％有效条件下均出现了显著的返回抑制。但由于注意定势的作用。20％有效条件下的返回抑制量要明显高于50％有效条件;而在80％有效条件下．没有出现返回抑制。并且外显地形成相关注意定势的被试显示出显著的返回抑制的反转。而没有外显地形成相关注意定势的被试则显示出了返回抑制效应。这表明,内源性的注意定势对返回抑制的质和量都有重要影响。适当的注意定势可以在任意方向上改变返回抑制。     

制度研究的哲学视野选择及其问题梳理

由于制度在现代社会发展中不可或缺的地位与作用,使得学术理论界对于制度问题的研究给予了相当的重视.很多的学科,像制度经济学、制度政治学、历史社会学、法哲学等对于经济制度、政治制度、社会制度、法律制度等不同类型、不同层次的制度的具体内涵及其实施运行机理等内容,都进行了深入而又卓有成效的研究.相比之下,对"制度"本身的哲学理性认识和反思尚显不足.从制度元问题的层面、从世界观方法论的层面,借鉴各学科有益的研究方法,在各个学科已经取得的研究成果基础上进行哲学的、综合性的研究,无疑是有理论价值的.     

Exploring Factors Related to Young Children’s Word-Meaning Derivations During Read-Alouds

This study explores how child and text clues were related to 31 kindergarteners’ word-meaning derivation outcomes for 372 words presented in books read aloud to children. Data were analyzed using a multilevel, cross-classification, ordered logit model. Children showed no word-meaning derivation 40% of the time, indicating a need for instruction. Better word-meaning outcomes were related to text factors (written text clues in close proximity to the word) and child factors (literal comprehension and metacognition). Thus, using text with written clues in close proximity to the word and building children's literal comprehension and metacognition may improve word-meaning derivation.     

网络词语与非网络词语的知觉差异:时间知觉、空间距离知觉与知觉范围

根据具身认知理论,人们的认知会受到身体活动的影响。网络环境下人的身体活动受到限制,因而其认知活动与非网络环境存在很大的差异。本研究目的在于考察人们对网络词语与非网络的日常词语的时间知觉,空间距离知觉与知觉范围是否有差异。结果发现被试对网络词语的时间知觉更长;网络词语的空间距离感与日常词语没有显著差异;在启动网络词语之后,被试的知觉范围缩小,对中心刺激的反应显著快于边缘刺激。本研究发现了网络词语加工在时间知觉和知觉范围上的变化。     

生态化微表情识别测验EMERT的建立——对JACBART微表情识别测验的改进与发展

经典JACBART微表情识别测验只考察平静表情背景下微表情识别,生态效度不高。本研究创建生态化微表情识别测验,考察所有7种基本表情背景下的6种微表情识别特征。结果发现:(1)该测验具有良好的重测信度、校标效度和生态效度,能够稳定有效地测量生态化微表情识别。(2)信效度检验揭示了生态化微表情识别特征。某些生态化微表情识别存在训练效应。生态化微表情与经典微表情或普通表情普遍相关。恐惧、悲伤、厌恶、愤怒微表情背景主效应显著;惊讶和愉快微表情背景主效应不显著,成对比较发现各背景下惊讶/愉快微表情差异不显著,但是与普通表情有广泛的显著差异。用不同背景下微表情识别正确率的标准差定义生态化微表情识别波动,发现生态化微表情识别具有稳定的波动性。     

表象编码方式影响错误记忆的研究

考察表象编码方式对错误记忆的影响。结果发现,与整合表象编码比,个别表象编码能够促进项目的特异性加工,使项目更有区分性,阻止(或减弱)诱饵词的内隐表象激活,有利于个体获取表象的激活路径,减少错误记忆发生,说明表象编码方式对错误记忆具有重要影响。根据研究结果提出表象激活混淆假设,认为个体虽然可以使用表象作为信息表征方式,却无法直接获取与之联系的激活路径。当个体推测表象激活的来源时,容易混淆表象激活的来源,错误记忆就发生了。表象激活混淆假设为视觉表象引发错误记忆的心理机制提供了说明。     

Self-concept integration and differentiation in subclinical individuals with dissociation proneness

Dissociative pathology is characterized by an altered sense of self. Still, it remains unclear (a) whether the altered sense of self is also associated with non-pathological dissociation as well and (b) whether this potential association is an intrinsic connection or a consequence of other related constructs, including childhood trauma. This study addresses this question by examining how self-concept organization may differ among individuals with different levels of dissociation proneness. The structure of self-concept was operationalized by various indexes of self-concept integration and differentiation. Results showed that individuals high in dissociation proneness have lower self-concept clarity and compartmentalize self-aspects with more polarized evaluations. Notably, the association between dissociation proneness and evaluative self-compartmentalization held after controlling for childhood trauma, anxiety, and depression. This characteristic self-concept organization can be an attribute of non-pathological dissociation.
