In his comment, Black (AA 526 155) argued that Maier and Seligman (EJ 138 911) incorrectly interpreted competing motor response explanations of the learned helplessness effect. Here, it is argued that no article that has proposed a competing motor response explanation of the learned helplessness effect has alluded to a mechanism similar to the one…

Suggests that penis envy leads to punishment of sexual aggression, and several psychoanalytic hypotheses for further experimentation on this construct are presented. (Editor)

Practical significance is concerned with whether a research result is useful in the real world. The use of procedures to supplement the null hypothesis significance test in four journals of the American Psychological Association is examined, and an approach to assessing practical significance is presented. (SLD)

The relative merits of two prominent lines of inquiry into the linkage between organizational culture and effectiveness (culture type and strong culture hypotheses) were studied with 334 colleges and universities. Findings support both approaches and suggest that alternative culture types are differentially effective on different performance…

Discussion of electronic commerce and online marketing focuses on an empirical study that investigated differences between Internet shopping intentions for products categorized by cost and tangibility. Highlights include hypotheses; respondent characteristics; results that showed that intentions to shop using the Internet differ by tangibility of…

Describes a direct linear relation between the number of articles in a journal and the journal's impact factor. Hypotheses are presented; theoretical considerations are discussed; and results are described that show exceptions for review journals and translation journals, as well as for journals in mathematics and chemistry. (Author/LRW)

Presents a theory of distance education to demonstrate its potential, based on a discussion of the concept of theory in general. Topics include the scope of a theory of distance education, generating hypotheses, descriptive elements and testable hypotheses generated, and the potential and applicability of the theory suggested. (71 references) (LRW)

An extension of the discussion of loglinear models presents post hoc procedures for statistically evaluating treatment effects, contrasts, and confidence intervals, illustrating methods for main effect and interaction contrasts and paying special attention to odds ratios and their interval estimates. Procedures for treating variables as…

A distinction is made between statistics based on scientific theory and theory-free statistics. This distinction is discussed in the contexts of hypothesis testing, Bayesian inference, a priori planned contrasts, a new simple computational method, and alternative data interpretations. (TJH)

In multigroup covariance structure analysis with structured means, the traditional latent selection model is formulated as a special case of phenotypic selection. Illustrations with real and simulated data demonstrate how one can test specific hypotheses concerning selection on latent variables. (SLD)

Examines documents and citations relating to literature of the Ortega Hypothesis, reviews citing behaviors and errors of individual citations, and includes analysis of the occurrences of secondary and tertiary citing. Findings show there is little evidence to prove that secondary and tertiary citing is not occurring and suggests that further…

This discussion of the discovery process in science suggests that discoveries are often made by a pattern recognition process which includes elaboration of a perceived pattern involving development of a descriptive vocabulary, elucidation of mathematical relations and measures, development of measurement instruments and techniques, and deduction…

Two experiments examined the hypothesis that aging is associated with an increase in schema-related influences on memory performance. Attention allocated during the study was disrupted more by lack of scene organization in older adults. There were relatively systematic age differences for retention. (RH)

Criteria for factor identification in factor analysis according to J. Algina (1980) are summarized, and a procedure is presented to determine rotationally underidentified factors by adding restrictors and to carry out the rotation for old and new restrictions and in latent path analysis. Two illustrations are presented. (SLD)

Compares face-to-face negotiation outcomes with computer-mediated negotiation outcomes using an integrative (win-win) negotiation. Highlights include the use of electronic mail; literature reviews on negotiation literature, computer-mediated communication literature, and computer-mediated negotiation literature; hypotheses tested; Pareto…
