数字空间联结的工作记忆机制

大量研究证实数字空间联结是一种稳定存在的表征形式。而关于数字空间联结的机制目前仍存在较大争论,本文在系统整理了大量有关长时记忆"心理数字线"难以解释的研究后,分析总结了工作记忆在数字空间联结中的重要作用。基于多个研究任务分析了工作记忆不同成分,即中央执行、语音环路和视空模板等,在数字空间联结中的重要作用,并系统介绍了对数字空间联结的工作记忆序列位置的解释。总之,数字空间联结的工作记忆机制仍有较多需要解决的问题,具有进一步探索的广泛空间。     

Exploring Child and Parent Factors in the Diagnostic Agreement on the Anxiety Disorders Interview Schedule

Worryingly low levels of parent–child agreement on child psychiatric diagnosis are reported. This study examined parent–child agreement on diagnostic categories and severity ratings with the Anxiety Disorders Interview Schedule, Child and Parents versions (ADIS-C/P). Children’s age, gender, motivation and self-concept and parent’s general psychopathology and diagnoses were examined. Participants were 110 children (aged 8–14 years) with a principal specific phobia diagnosis, and their parents. Findings revealed excellent parent–child agreement on principal specific phobia diagnosis (97.3%), and fair levels of concordance on most co-occurring secondary diagnoses. As expected, children with high motivation had generally stronger parent–child agreement on diagnoses and severity ratings (for ADHD p?p?p?相似文献   

浅析死刑认同的心理根源

我国民众普遍认同死刑,这种"死刑认同"具有三种心理情绪根源:死亡情结、社会情感以及正义报复感。死刑认同实质上是国民的一种个人情绪和社会情感的表达和要求。取消死刑是必然趋势,但必须具备相应的社会条件。     

ERP Evidence for the Rapid Assignment of an (Appropriate) Antecedent to PRO

Event-related brain potentials were recorded while subjects listened to sentences containing a controlled infinitival complement. Subject and object control items were used, both with 2 potential antecedents in the upper clause. Half of the sentences had a gender agreement violation between the null subject of the infinitival complement and an adjective predicated of it. The rapid detection of this anomaly would indicate that the parser had established the coreference relation between the null subject and an antecedent, and that the processor had rapidly consulted verb control information to select the proper antecedent of the null subject. The results showed that for both subject and object control items ungrammatical adjectives elicited a P600 effect. These data imply that the processor has coindexed the null subject with an antecedent, and that the antecedent has been selected on the basis of control information. These results are compatible with parsing models that emphasize the rapid influence of verb-specific information on sentence processing.     

Selecting polychoric instrumental variables in confirmatory factor analysis: An alternative specification test and effects of instrumental variables

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different numbers of IVs. Our results show that specification tests derived for continuous data are extremely oversized at all sample sizes when applied to ordinal variables. Possible modifications for ordinal data are proposed in the present study. Simulation results show that the modified specification tests with all available IVs are able to detect model misspecification. In terms of estimation accuracy, the PIV approach where the IVs outnumber the endogenous variables by one produces a lower bias but a higher variation than the PIV approach with more IVs for correctly specified factor loadings at small samples.     

多层次研究的数据聚合适当性检验:文献评价与关键问题试解

组织管理领域的多层次研究经常需要测量共享单位特性构念, 常用方法是将单位内若干个体成员的评分聚合到单位层次, 确保聚合后的分数具有充分代表性的统计前提是通过聚合适当性检验。聚合适当性检验的常用指标是组内一致性r_WG和组内信度ICC(1)、ICC(2), 但目前学界对于这两类指标何者更优、r_WG的原分布选择和数据清理、各指标的划界值等关键问题存在诸多争议。为此, 首先对国内9份管理学、心理学期刊2014年以来发表的166篇包含聚合适当性检验的论文进行内容分析, 并以Journal of Applied Psychology上的85篇论文为对比, 查明常规实践中的共性问题, 进而提出实践建议:(1)明确功能定位, 将r_WG作为聚合适当性指标, ICC(1)和ICC(2)分别作为效度、信度指标。(2)计算r_WG时审慎选择原分布, 排除组内一致性过低的组。(3)为各指标设定更加合理、有适度灵活性的划界值, 停止使用武断、粗糙的经验标准。最后, 强调研究者在模型构建和聚合决策中应加强理论考量, 避免片面依赖统计检验结果。     

Alternate methods and software for calculating interobserver agreement for continuous observation data

Portable electronic data collection devices permit investigators to collect large amounts of observational data in a form ready for computer analysis. These devices are particularly efficient for gathering continuous data on multiple behavior categories. We expect that the increasing availability of these devices will lead to greater use of continuous data collection methods in observational research. This paper addresses the difficulties encountered when calculating traditional interobserver agreement statistics for continuous, multiple-code scoring. Two alternative strategies are described that yield interobserver agreement values based on the exact time of behavior code entries by the primary and secondary observers.Work on this paper was supported in part by NICHD Grants P01HD15051 and R01HD17650 and Office of Special Education and Rehabilitation Services Grant G008302980.     

An entropy approach to the scaling of ordinal categorical data

This paper studies the problem of scaling ordinal categorical data observed over two or more sets of categories measuring a single characteristic. Scaling is obtained by solving a constrained entropy model which finds the most probable values of the scales given the data. A Kullback-Leibler statistic is generated which operationalizes a measure for the strength of consistency among the sets of categories. A variety of data of two and three sets of categories are analyzed using the entropy approach.This research was partially supported by the Air Force Office of Scientific Research under grant AFOSR 83-0234.
