Social comparison theory predicts that when the person is uncertain about the level of his ability, he may seek comparison information through competitive behavior. An experiment is reported in which the level of the subject's uncertainty about his competence was manipulated and subsequent measures of his competitive motivation and behavior were…

Two free-recall experiments were performed in which the subjects were required to rehearse items an equal number of times, but the number of items presented at a given time was varied. The main hypothesis was that increasing the number of items presented at once would increase processing demands and decrease performance. (Editor)

Three linear models (Fixed, Random, and Provisional) and their inferential counterparts are presented and discussed. The three linear models are considered in relation to the analysis of nonlinearity, and limitations in the use of polynominal and product variables are discussed. Several exemplary research papers are examined and reconsidered in…

Three hypotheses are tested in order to reveal racial differences in the reaction to Watergate in a sample of 944 high school seniors in Atlanta; the partisanship, social deprivation, and political reality hypotheses. (Author/AM)

These experiments are addressed specifically to the question of whether transituational transfer of immunizing and therapeutic effects will occur when these procedures involve responses and settings which are very different from those used in final testing. (Author/RK)

A free association technique was used to investigate the semantic structure of three forms of encoding: verbal, visual imagery, and kinesthetic imagery. Discusses the relevance of these findings to creativity and the concept of semantic memory. (Editor/RK)

It has been demonstrated that instructions to learn have no effect on immediate recall in the incidental learning paradigm used by Jenkins (1974). This research further investigated this finding by factorially manipulating recall instructions (incidental vs. intentional learning), presentation rate of materials, retention interval, and type of…

Two experiments investigated the relationship between social influence and the number of persons attempting influence. Findings suggest that the manner in which persons are initially organized into groups and aggregates of individuals affects their persuasive impact on observers. (Editor/RK)

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. (Editor)

Describes an experiment that tested the effects of a vertical versus a horizontal arrangement of brief structured text entries on know-item search time. The results discussed include the effects of the searcher's age and entry arrangement on search times, and subjects' judgments on the ease of use of the entry arrangements. (Author/CLB)

Tests several hypotheses derived from the Guttentag-Secord theory which relates societal-level sex ratios to women's status and roles. Finds that the effects of sex ratio on women's roles are more pronounced in developed countries but that correlations between sex ratio and certain dimensions of women's roles provide little support for the theory.…

For the conditions investigated in the study, the parametric ANCOVA was typically the procedure of choice both as a test of equality of conditional means and as a test of equality of conditional distributions. (Author/LMO)

Five experiments were performed to determine whether different amounts of attention were demanded of readers under the following conditions: (1) during the reading of relevant segments of text prefaced by questions; (2) by questions following relevant segments of text; and (3) during the reading of prefatory questions. (LMO)

Khuri's and Satterthwaite's methods of obtaining confidence intervals of variance components are compared. The article discusses that Khuri's method may be applied to obtain confidence intervals for the variance components and other linear functions of the expected mean squares used in generalizability theory.
