Computation of a one-way analysis of variance (ANOVA) "F" ratio from descriptive statistics in the absence of raw data is corrected from two sources. Means associated with inferential statistical hypotheses are identified as estimable population parameters. (Author)

Responds to previous article by Fincham, Beach, Moore, and Diener (this issue) on child sexual abuse. Focuses on importance of recognizing that attempts to reduce probability of false claims of child abuse would result in increasing probability of missing true claims of child abuse. Offers hypothesis-testing framework as useful heuristic for…

Describes a study that examined the rates of use of descriptors in the ERIC (Educational Resources Information Center) system during 1966-86 to determine whether certain levels of terms were used more than others and whether patterns of use were similar among hierarchies in the ERIC Thesaurus. (10 references) (LRW)

Results of a study of low-income, inner-city mothers and their 13-month-old infants supported the hypothesis that increased physical contact achieved through the use of a soft baby carrier makes mothers more responsive to their infants and promotes the formation of more secure attachment between infants and mothers. (RH)

Describes the development of "Europe in the Round," a CD-ROM that was designed to test the hypothesis that a combination of hypertext with mass storage would make a powerful learning tool. Screen design is discussed, including universal icons and visual effects, and field testing is described. (five references) (LRW)

Two forms of Holland's Hexagon Model (circular order and circumplex structure) are proposed and evaluated to demonstrate a randomization test of hypothesized order relations and confirmatory factor analysis. The models and methods are illustrated with correlation matrices based on the Unisex Edition of the ACT Interest Inventory. (Author/SK)

Research on the direct-product model is extended by deriving hierarchically nested models for explicitly testing the patterns of method and trait factors and through formal tests developed for the pattern of communalities. These procedures are illustrated, and use of the MUTMUM computer program is discussed. (SLD)

Seven univariate procedures for testing omnibus null hypotheses for data gathered from repeated measures designs were evaluated, comparing five alternative approaches with two more traditional procedures. Results suggest that the alternatives are improvements. The most effective alternate procedure in controlling Type I error rates is discussed.…

This article shows how a multivariate approximate degrees of freedom procedure based on the Welch-James procedure as simplified by S. Johansen (1980) can be applied to the analysis of repeated measures designs without assuming covariance homogeneity. A Monte Carlo study illustrates the approach. (SLD)

This article presents a didactic discussion on the role of asymptotically independent test statistics and separable hypotheses as they pertain to issues of specification error, power, and model misspecification in the covariance structure modeling framework. A small population study supports the major findings. (SLD)

Significance tests are often used inappropriately in counseling research. In addition to comments on the significance test controversy (Vacha-Haase and Nilsson, this issue), a wider historical context and personal experiences are provided. The controversy is discussed, and seven recommendations for using significance tests are included. (EMK)

Introduces the three subsequent articles from this special section, which extend the discussion of future prospects for progress in the reporting and interpreting of effect sizes by researchers. The authors of these pieces represent diverse views. (SLD)

Describes student-led research projects conducted at the University of Florida's General Clinical Research Center. First-year medical and M.D.-Ph.D. students collaborate on a hypothesis-driven experiment involving students as volunteer subjects and investigators. Feedback indicates students find the program useful and that it encourages pursuit of…

Tests the hypothesis that a fifth stage of intellectual development characterized by the ability to test alternative explanations involving unseen theoretical entities exists. This hypothesis is tested in the context of a nonmajor college-level biology course in which the assumption is made that some students have acquired Stage 5 reasoning…

Discussion of the use of color for enhancing recognition memory focuses on a study of undergraduates that evaluated images as black and white, full color, or highlight color and the effect these characteristics had on recognition memory and recall for learners classified as field-dependent and field-independent in terms of cognitive style.
