The recommendation to base the analysis of multi-wave data upon explicit models for change is advocated. Several univariate and multivariate models are described, which emerge from an interaction between the classical test theory and the structural equation modeling approach. The resulting structural models for analyzing change reflect in some of their parameters substantively interesting aspects of intra- and interindividual change in follow-up studies. The models are viewed as an alternative to an ANOVA-based analysis of longitudinal data, and are illustrated on data from a cognitive intervention study of old adults (Bakes et al , 1986). The approach presents a useful means of analyzing change over time, and is applicable for purposes of (latent) growth curve analysis when analysis of variance assumptions are violated (e.g., Schaie & Hertzog, 1982; Morrison, 1976). 相似文献

字频在直接和间接记忆测验中的比较研究 总被引:2,自引:1,他引:1
本研究通过3×2×2混合设计实验,比较了字频在即刻和第5天两种施测时间下的两类记忆测验中的不同作用。本研究支持了词汇通达搜索模型对宇频作用机制的分析及传输适当认知程序观点对实验性分离现象的解释,并发现外显记忆与内隐记忆都会发生遗忘,但原因可能并不相同,而且字频影响两类记忆的遗忘进程。 相似文献

An application of a future-oriented job analysis (FOJA) procedure used to gain an understanding of newly formed entry-level positions in a large insurance organization is described. A brief review of the relevant literature is presented to serve as a foundation upon which to consider the current FOJA procedure. Specific assumptions, stages, and results of the current procedure are detailed. The benefits of this application of FOJA are also discussed. 相似文献

利用计算机构造被试总体、模拟实验研究程序进行抽样研究,探讨抽样样本总体达到t检验显著性的数目与统计检验能力之间的一致性。模拟实验结果表明,统计检验能力与样本总体t检验显著性的数目具有很高的一致性,但两者同时受到显著性水平α、样本客量n和总体效果大小δ的影响,从而有可能影响统计推断的可靠性。因此,在进行显著性检验过程中,应对统计检验能力进行估计,这将有利于心理学研究成果的积累。 相似文献

75 adolescent psychiatric patients were diagnosed with the perceptual projective test the Defense Mechanism Test (DMT) and also according to Kernberg's theory of personality organization (PO). The test protocols were scored in respect of 130DMT variables and analyzed by means of partial least squares (PLS) discriminant analysis. The objective was to try to separate the three types of PO, psychotic (PPO), borderline (BPO) and neurotic (NPO) by means of the DMT and also to compare the results with a similar study on adult psychiatric patients. The results showed that it is possible to separate significantly the three groups of PO. The BPO group seemed to be heterogeneous. The results were fairly similar to those obtained with adult psychiatric patients. The overall results supported the concurrent validity of Kernberg's theory of PO and for the DMT as well. The DMT seems to be a useful diagnostic method in respect of adolescent psychiatric patients. 相似文献

Iterated revision and minimal change of conditional beliefs 总被引:5,自引:0,他引:5
Craig Boutilier 《Journal of Philosophical Logic》1996,25(3):263-305
We describe a model of iterated belief revision that extends the AGM theory of revision to account for the effect of a revision on the conditional beliefs of an agent. In particular, this model ensures that an agent makes as few changes as possible to the conditional component of its belief set. Adopting the Ramsey test, minimal conditional revision provides acceptance conditions for arbitrary right-nested conditionals. We show that problem of determining acceptance of any such nested conditional can be reduced to acceptance tests for unnested conditionals. Thus, iterated revision can be accomplished in a virtual manner, using uniterated revision. 相似文献

阿拉伯数字与汉字大写数字认知的大脑功能一侧化实验研究 总被引:3,自引:0,他引:3
用半视野速示术检查阿拉伯数字和汉字大写数字在三种任务加工条件(认读、简单相加、奇偶概念异同判断)下进行认知的大脑两半球机能活动一侧化效应。结果表明:以被试正确反应的百分数为指标,两类数字的三种任务加工均没有表现出明显的视野(大脑半球)优势。以被试正确反应的反应时为指标,两类数字的认读和简单相加也未出现视野(大脑半球)的明显差别,而两类数字的奇偶概念异同判断却出现了差异显著的右视野(左半球)优势。 相似文献

Repeated measures designs in psychology have traditionally been analyzed by the univariate mixed model approach, in which the repeated measures effect is tested against an error term based on the subject by treatment interaction. This paper considers the extension of this analysis to designs in which the individual repeated measures are multivariate. Sufficient conditions for a valid multivariate mixed model analysis are given, and a test is described to determine whether or not given data satisfy these conditions. 相似文献

The problem of predicting universe scores for samples of examinees based on their responses to samples of items is treated. A general measurement procedure is described in which multiple test forms are developed from a table of specifications and each form is administered to a different sample of examinees. The measurement model categorizes items according to the cells of such a table, and the linear function derived for minimizing error variance in prediction uses responses to these categories. In addition, some distinctions are drawn between aspects of the approach taken here and the familiar regressed score estimates.The author thanks Robert L. Brennan, Michael J. Kolen, and Richard Sawyer for helpful comments and corrections, and anonymous reviewers for suggested improvements. 相似文献

For ordinal measurement the concept of an individual propensity distribution is developed. For any given individual the mean of this distribution is his true score, for which estimation procedures are discussed. Two measures of individual dispersion are considered and their distributions derived in the null case. These measures are shown to be counterparts at the individual level of Kendall's tau and Spearman's rho. Estimation of the two dispersion measures from sample data is investigated, and the relation of these estimates to the variance of the individual propensity distribution is derived. 相似文献
