Subjects were trained against their initial dimensional preference in a two-dimensional simultaneous discrimination learning task. (RH)

In a conceptual replication and extension of a study by Bem and Lenney, male (n=90) and female (n=118) college students rated their comfort in and preference for performing several series of masculine, feminine, and neutral activities. (MP)

Hawkin's procedure for testing a sequence of observations for a shift in location could have applicability for assessing change within a single subject. Monte Carlo results suggest that Hawkins' procedure is robust with respect to moderate violations of its underlying assumptions of homogeneity of variance and normality. (Author/GDC)

Errors of misclassification and their effects on categorical data analysis are discussed. The chi-square test for equality of two proportions is examined in the context of errorful categorical data. The effects of such errors are illustrated. A correction procedure is developed and discussed. (Author/MH)

Evaluations involving nonrandom assignment to treatment or control groups are vulnerable to an accidental or intentional confounding of a selection effect with the treatment effect. Two techniques, discriminant analysis and base expectancy analysis, permit separate estimation of the selection and treatment effects in the final results. (Author/CTM)

A data analysis procedure for testing the hypothesis that one task is a developmental prerequisite for another task is illustrated. The procedure was applied to new data on the acquisition of conservation concepts to test the hypothesis that synthesis, visual-scanning skills, and memory capacity are prerequisites of conservation mastery. (JMB)

Argues that current teaching of scientific inquiry overemphasizes hypothesis testing to the exclusion of hypothesis generation. (SL)

Examines children's readers to find out whether Riesman, Glazer, Denney, and William F. Whyte's descriptions of changes in the American character are represented in the models offered to school children. Compares the models used in the early McGuffey Readers with contemporary readers. (Editor/RK)

An attempt was made to delineate the degree to which distortions in the perception of depression were related to the severity level of the patient's depression and the degree to which denial was utilized as a coping mechanism. (Author)

Attempts to discover if there was a significant relationship between the clothing behavior of two different groups of college males (identified as conservative dressers and hippie dressers) and their social-political beliefs. (Author/RK)

Focuses on selecting learning experiencing which allow students direct involvement in the discussion of issues most important to them. Reports research findings from a 1971 study of marital role expectations of high school students in a large Alberta city and outlines teaching strategies which utilize this data. (Author/RK)

Investigates the prediction that the usual superiority of pictures over words for repetitions of the same items would disappear for items that were different instances of repeated categories. (Author/RK)

Tests whether children's learnings in one of the social sciences, geography, are as hypothesized, hierarchically dependent; that is, whether learning of each in a series of central, analytic processes in one of the social sciences facilitates, through positive transfer, the learning of each succeeding higher-order capability in the field.…

This research was designed to measure how students enrolled in introductory marketing courses perceived mass section multimedia lecture classes in comparison with other commonly utilized teaching formats. (Author/RK)

Attempts to define the relationships between four measures of recall in a two-recall task, namely (a) initial short-term recall (STR), (b) unconditional final free recall (FFR), (c) final free recall conditionalized on an initial successful recall (FFR/STR), and (d) final free recall conditionalized on an unsuccessful recall (FFR/STR).
