Effect size, power, and sample size determination for structured means modeling and mimic approaches to between-groups hypothesis testing of means on a single latent construct

While effect size estimates, post hoc power estimates, and a priori sample size determination are becoming a routine part of univariate analyses involving measured variables (e.g., ANOVA), such measures and methods have not been articulated for analyses involving latent means. The current article presents standardized effect size measures for latent mean differences inferred from both structured means modeling and MIMIC approaches to hypothesis testing about differences among means on a single latent construct. These measures are then related to post hoc power analysis, a priori sample size determination, and a relevant measure of construct reliability.I wish to convey my appreciation to the reviewers and Associate Editor, whose suggestions extended and strengthened the article's content immensely, and to Ralph Mueller of The George Washington University for enhancing the clarity of its presentation.     

Wilson on Circular Arguments

This paper criticizes Kent Wilson's (`Circular Arguments', 1988) arguments against the analysis of the fallacy of begging the question in epistemic terms and against the division of the fallacy into equivalence and dependency types. It is argued that Wilson does not succeed in showing that the epistemic attitude to the fallacy analysis should be given up. Further, it is argued that Wilson's arguments against the division of the fallacy into two types can be overcome by altering the accounts he criticizes (David Sanford (1971, 1984, 1988) and John Biro (1977, 1984)): fallacy analysis should concentrate on externalized arguments, but this does not mean that either the epistemic attitude or the dependency conception should be given up.     

组织研究中的多层面问题

多层面理论（multilevel theory）已成为组织研究中的一个新范式,它可以研究微观和宏观二者之间的交互作用。为了给组织研究者提供一个思考和决策框架,文章在简要回顾多层面研究的来源后,介绍了3种集体层面的结构、集体层面结构的5种“构成模型”（composition model）、以及1个判断框架,并介绍了多层面研究中常用的4个论证指标（rwg、ICC（1）、ICC（2）、WABAI）的算法和区别,最后对常用的3种分析方法（WABA：within-and-between-analysis、HLM：hierarchical linear modeling、CLOP：cross-level operator）进行了简单介绍和比较。     

内隐和外显记忆测验的信度比较研究及思考

任务分离的实验范式以功能分离和随机独立性等证据说明不同记忆任务的底层系统或加工机制。近期研究发现,两种记忆测量重测信度、复本信度和分半信度差异显著,内隐测验的信度更低一些,因而对变量效果缺乏足够的敏感性。两种测验信度差异对任务分离提出了区别于系统说或加工观点的另外解释。以后在研究外显和内隐记忆分离的时候应该慎重考虑测验信度的检验问题,还应通过各种方法来提高内隐记忆测验的信度,使两种记忆测验的信度具有可比性。

Derived relational responding as generalized operant behavior

The major aim of the present study was to demonstrate that derived relational responding may be viewed as a form of generalized operant behavior. In Experiment 1, 4 subjects were divided into two conditions (2 in each condition). Using a two-comparison matching-to-sample procedure, all subjects were trained and tested for the formation of two combinatorially entailed relations. Subjects were trained and tested across multiple stimulus sets. Each set was composed of novel stimuli. Both Conditions 1 and 2 involved explicit performance-contingent feedback presented at the end of each block of test trials (i.e., delayed feedback). In Condition 1, feedback was accurate (consistent with the experimenter-designated relations) following exposure to the initial stimulus sets. When subjects' responding reached a predefined mastery criterion, the feedback then switched to inaccurate (not consistent with the experimenter-designated relations) until responding once again reached a predefined criterion. Condition 2 was similar to Condition 1, except that exposure to the initial stimulus sets was followed by inaccurate feedback and once the criterion was reached feedback switched to accurate. Once relational responding emerged and stabilized, response patterns on novel stimulus sets were controlled by the feedback delivered for previous stimulus sets. Experiment 2 replicated Experiment 1, except that during Conditions 3 and 4 four comparison stimuli were employed during training and testing. Experiment 3 was similar to Condition 1 of Experiment 1, except that after the mastery criterion was reached for class-consistent responding, feedback alternated from accurate to inaccurate across each successive stimulus set. Experiment 4 involved two types of feedback, one type following tests for mutual entailment and the other type following tests for combinatorial entailment. Results from this experiment demonstrated that mutual and combinatorial entailment may be controlled independently by accurate and inaccurate feedback. Overall, the data support the suggestion, made by relational frame theory, that derived relational responding is a form of generalized operant behavior.     

Development and validation of Swedish classical and modern sexism scales

In two studies we develop and validate a Classical--overt or direct--and a Modern--covert or subtle--Sexism Scale concerning attitudes toward women, for a Swedish (Scandinavian) context. Further, we examine whether these two forms of prejudice are distinguishable. Confirmatory factor analyses showed that, although highly correlated, classical and modern sexism are distinguishable. The construct validations showed that men had higher means on modern and classical sexism scores than women, and that our scales were related to other constructs as expected. In a third study, we analyzed the knowledge and the content of cultural stereotypes about women. There were no differences in the knowledge of cultural stereotypes between men and women or between high- and low-sexist individuals. The findings are discussed in relation to previous international studies that examine people's modern and/or classical sexism.     

The structure of equivalence classes

THE STRUCTURE OF EQUIVALENCE CLASSES CAN BE COMPLETELY DESCRIBED BY FOUR PARAMETERS: class size, number of nodes, the distribution of "singles" among nodes, and directionality of training. Class size refers to the number of stimuli in a class. Nodes are stimuli linked by training to at least two other stimuli. Singles are stimuli linked by training to only one other stimulus. The distribution of singles refers to the number of singles linked by training to each node. Directionality of training refers to the use of stimuli as samples and as comparison stimuli in training. These four parameters define the different ways in which the stimuli in a class can be organized, and thus provide a basis for systematically characterizing the properties of stimuli in a given equivalence class. The four parameters can also be used to account for the development of individual differences that are commonly characterized in terms of "understanding" and connotative meaning.Methods are described for generating all possible combinations of parameter values, and a formula is introduced which specifies all of the parameter values for an equivalence class. Its utility for interrelating experimental procedures is demonstrated by analyzing a number of representative experiments that have addressed equivalence-class formation.     

The psychometric properties of several measures of body image

Despite the recent upsurge of interest in the construct of body image, there is relatively little information on the psychometric properties of the instruments used to measure it. This study investigated the reliability and validity of several measures of body image and compared bulimics and normals on these measures. One hundred ten normal weight females, half of whom were diagnosed as bulimic, were administered two measures of affect toward one's body, two measures of perceptions of one's entire body, and three measures of perceptions of the size of specific body sites (face, shoulders, waist, and hips). In themain, the measures provided reliable indices of body image. Examination of the correlation matrix for the measures disclosed convergence for the affective measures of body image and for all but one of the perceptual measures of body image. There was also significant covariation between the affective and the perceptual measures. The multitrait-multimethod technique was used to investigate the construct validity of the measures concerned with perceptions of the size of body sites. The multitrait-multimethod matrices disclosed substantial convergence between perceptions of face, shoulder, waist, and hip size across the three measures. However, the measure which used kinesthetic estimates of body-site size produced low reliabilities and all three of the measures showed substantial method variance. Bulimics and normals differed significantly on both the affective and the perceptual components of body image.This study is based on the first author's masters thesis. Portions of this study were represented at the 1986 meeting of the Southeastern Psychological Association. A grant to the third author from the Anclote Psychiatric Center provided support for this research project.
