The purpose of this study was to examine the nature of the expectancy-performance relationship for each sex and to determine whether cross-sex comparisons are appropriate. Students' expectancies for academic performance and the relationship of the expectancies to actual grades were examined. Subjects were 331 students (168 women and 163 men)…

This report addresses the problem of sample size in developing prediction equations for college freshman grade averages under the American College Testing (ACT) Assessment Program. For the ACT Assessment, the prediction weights are estimated by standard least squares procedures. Because prediction weights are estimated regression coefficients…

The single parent who has to assume the role and the responsibilities of both mother and father provides a different sex-role model for the child than that provided in the two-parent family. Research has indicated that single parents are more androgynous than parents in intact families. To investigate the sex roles of 332 college students (213…

A model of internal principle for integrating past research findings on adult altruism postulates that although individuals' shared beliefs result in significant group effects, there remains a significant portion of variation due to a subject's "factor" or unique internal rule. To examine the influence of both the level (degree or amount) and the…

The purpose of the present longitudinal study was to determine how well a broad, comprehensive battery of tests administered in kindergarten predicts reading achievement in elementary school grades 1 through 6. The test variables were reduced to six predictive factors by factor analysis, and these, together with the variables, Child's Sex and…

Inconsistencies in the use of terminology to describe instructional treatments, confounding of discovery and expository methods with other aspects of instruction, and inconsistencies in defining independent and dependent variables within and between studies have all contributed to the lack of definitive conclusions about the effectiveness of…

One of the important components of the elaboration theory (Reigeluth, 1979) is the synthesizer, which provides information to relate and integrate a set of concepts and which can appear in different formats. This study investigated the effectiveness of three formats of post-instruction synthesizer on student recall of definitions of concepts and…

With the proliferation of suicide prevention centers in the United States, the task of rapidly and effectively assessing an individual caller's suicide potential has become an important research problem. However, the social science researcher is often confronted with an ethical problem when the results of his predictive equations can be used to…

This paper describes the self-evaluation maintenance model (SEM) which suggests that much social behavior can be understood by assuming that persons are motivated to maintain a positive self-evaluation. The two processes by which one's social circumstances may affect self-evaluation, i.e., reflection and comparison, are described. The relationship…

This report reviews five studies dealing with drug abuse and adolescence and presents an overview of the social changes which have contributed to the increased use of marijuana and other illicit drugs. The importance of the longitudinal study as a research tool is emphasized in describing the research projects that deal with the epidemiology of…

Fully addressing most problems clients bring to therapy usually requires more than one session. Some student therapists seem to be more capable than others of engaging clients and promoting more visits when warranted. To discover whether graduate admissions information can predict a psychologist-trainee's ability to readily engage clients, data…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

The purpose of this study was to determine which personality traits as measured by the California Psychological Inventory (CPI) are predictive of academic achievement in urban college freshmen of the Federal City College. The measures of achievement were grade point average (GPA) and the Comparative Guidance and Placement Program (CGPP) test…

This study is a cross-section regression analysis of male-female wage differentials in urban labor markets. Data for the study were obtained from the 1967 Survey of Economic Opportunity. A prime objective of this dissertation is to determine how much of the observed male-female wage differential can be attributed to the effects of discrimination…

Criteria and methods for developing a taxonomy for different situational categories are presented. (CK)
