Texts often suggest running preliminary tests for homogeneity of variance prior to running an ANOVA. While it has been known for some time that most of the suggested tests are probably not appropriate, they are still being used. This paper is a review of the literature in terms of the implications involved in running preliminary tests in general…

Neglected issues of simultaneous statistical inference and statistical power in survey research applications of the general linear model are reviewed, and it was found that classical hypothesis testing as it is currently applied, is inadequate for the purposes of social research. The intelligent use of statistical inference demands control over…

Four experiments gave direct tests of a popular hypothesis about the role of classical conditioning in person perception and social judgment. (Editor)

False-positive and false-negative decisions are the two possible errors committed with a mastery test; yet the estimation of the likelihood of committing these errors has not been investigated. Two methods of this type of estimation are presented and discussed. (Author/JKS)

The evidence for the effectiveness of the first letter mnemonic technique is confused. There are at least three studies showing no effect, and one where an improvement in recall occurred. Reports two experiments which attempted to locate the conditions under which the first letter mnemonic is effective. (Author/RK)

Examines the objectives of a 16-week course on how a professor can determine the degree to which traits of creativity have been developed in students. Also tests for creative thinking are evaluated. (Author/RK)

Attempts to help specify the boundary conditions for use of the recognition-recall method, i.e., recall made conditional upon recognition, and to use this method to evaluate a hypothesis about stimulus-concreteness effects with low-meaningful responses. (Author/RK)

Discusses words in statistical theory and practice with emphasis on the reality that words get short shrift in most statistical teaching and exposition. Uses common misuse of statistical words as example. (Author/RK)

The results of this study are interpreted as demonstrating a bias in favor of aiding and promoting members of one's own sex in managerial situations. (Author)

Jones (1976) has shown that the memory trace resulting from the viewing of a picture corresponds to a "fragment" of that picture. This research shows that the fragmentation hypothesis also correctly represents the recall of memories derived from sentences, i.e., the functional unit of memory, the mnemonic trace, is a fragment of the original item.…

35 undergraduates segmented one of two videotapes of an actor methodically assembling 20 five-page questionnaires. Tests the hypothesis that behavior that differs systematically in the availability of action-defining changes will be segmented into perceived actions in a systematically different way. (Author/RK)

An unobtrusive experimental manipulation was used to test the hypothesis that the mere presence of others can influence an individual's performance. A task was employed for which there were no clear performance criteria, and which was very unlikely to engender evaluation apprehension. Concludes that the mere presence of others is a sufficient…

An experiment was conducted to test the proposition that rewards undermine or enhance intrinsic interest in a task to the extent that individuals interpret their behavior as being motivated by the reward. It was predicted that when subjects were denied the opportunity to develop and confirm this attribution, rewards would not produce an…

Perspective ability is the ability to represent how objects look relative to each other from another person's viewpoint. This ability involves two different but interrelated skills: multiple classification and perspective-taking. The intent here was to devise a training program designed to study the causes of transition from one stage of…

This research tested the hypothesis that grouping has adverse effects on the recall of tactual shapes but facilitates the recall of tactual letters on the assumption that this depends on different processes. A further question was the relation of grouping to letter recall span (set-size).
