This comparison of regression discrepancy model results for learning disability identification used published IQ-achievement and reliability coefficients and generic, mean values. Use of mean IQ-achievement values resulted in higher discrepancy rates for a clinical sample. Use of both mean IQ-achievement and reliability values resulted in higher…

An adaptation of the multiple regression approach of De Fries and Fulker (DF analysis) is used to account simultaneously for genetic and environmental influences on achievement. The model was fitted to achievement measures of 1,044 related pairs of children from the National Longitudinal Study of Youth (NLSY). (SLD)

Provides evidence of detrimental effects of lead exposure on child behavior at levels typical of present-day exposure. Behavior and lead-blood level were examined for 201 African-American children aged 2 through 5 years. A standardized parent report measure and consideration of maternal morale are features of study methodology. (SLD)

The economic utility of the following 5 weighting methods for evaluating consumer loan applications was determined using a sample of 443 loans: (1) unit; (2) weighted application blank; (3) chi square; (4) Bayes; and (5) regression. The unit and weighted application blank procedures were the best approaches. (SLD)

This article addresses the international community's differing attitudes on mandatory retirement. The authors explored various factors, such as sociodemographics and political ideology and the latter's predictive value for attitudes on compulsory retirement. Education proved the strongest sociodemographic predictor. Most Americans opposed mandated…

A two-parameter logistic regression model for personnel selection is proposed. The model was tested with a database of 84,808 military enlistees. The probability of job success was related directly to trait levels, addressing such topics as selection, validity generalization, employee classification, selection bias, and utility-based fair…

Students tend to emphasize important information more than less important information in their lecture notes. Whether this strategy changes with lecture repetition was investigated in 3 experiments with 71 undergraduate students. Students' assessments and shifts of strategy with lecture repetition are discussed. (SLD)

Relations among observed family interaction patterns, preadolescent boys' classroom self-restraint, and academic achievement were studied in a sample of 65 intact families. Findings identify behavioral self-restraint, a form of social competence, as a noncognitive mediator between the quality of family functioning and academic achievement in early…

The reliability and validity of the revised California Psychological Inventory's (CPI) Vector 1 scale, a measure of introversion and extraversion, were studied with 345 college students (109 males and 236 females). Results support the scale as a valid measure of the introversion-extraversion construct of H. G. Gough. (SLD)

Summarizes British educational input-output analysis research, highlighting the extension of Michael Rutter's findings in "Fifteen Thousand Hours" (1979) by Steedman (1983) and Hough and Warburton (1986). Smith and Tomlinson's study of 3,000 children in 20 multiracial urban comprehensive schools found important interschool differences in…

Preschoolers at high risk for intellectual impairment were enrolled in an educational day care program. Repeated testing, with a control group, demonstrated that such a program could lessen the incidence of retardation. (DM)

Explores the causal nature of the association between grade repetition and later adolescent problem behaviors for 197 retained and 204 promoted African-American sixth and seventh graders in two urban middle schools. Regression analyses imply that retention reduced rebellious behavior in school and increased attachment to school. (SLD)

Uses ordinary least-squares multivariate regression analysis to determine if jurisdictional types vary in their willingness to increase taxation for schools, employing 892 education fund referenda conducted in Illinois from 1981 to 1989. Outcomes do differ by jurisdiction type. The strongest predictor is willingness to pay for higher taxes. (29…

Believes that the World Wide Web has great potential for delivering interactive computer-aided instruction using programming language like Java and Javascript. Describes a website on object-oriented microeconomics that integrates a textbook, mini-lecture series, graphical calculator, animated drawing program, spreadsheet, and regression package.…

The purpose of this split-sample regression study was to determine whether quantitative and verbal scores on the Graduate Management Admissions Test, undergraduate grade point averages, age, and gender differentially predicted performance for 198 MBA students. Findings suggest that commonly used predictor variables may predict achievement…
