Discusses the relationship between changes in delinquency prevalence over time and prediction error. Data from a 21-year British longitudinal study exemplify the formal relationships that are derived. Results indicate statistically, as prevalence increases, a relative increase in false negative errors and a decrease in false positive errors…

Looking back on enrollment trends in higher education in Britain since 1800, this study examines the trend toward expansion and the philosophy behind such expansion. A statistical model is developed for enrollment trends, and recent literature on enrollment is examined in light of the model presented. (MSE)

Kindergarten measures were significantly predictive of Anglo English speakers, somewhat less accurate for the Mexican American English-speaking group, and generally nonpredictive for Mexican American Spanish speakers. The tests were not language or culture specific. The importance of language as a factor in school screening is underscored. (Author)

Examined the usefulness of self-assessments of typing ability. Self-assessment of straight copy typing ability emerged as the best predictor of tested typing ability. Minority group members were generally less accurate in self-assessment of their typing ability. Presented at the Annual Convention of the American Psychological Association, Toronto,…

The computation, concept, and application subtests of the Stanford Achievement Tests (SAT) were administered to a student sample during grades 3, 5, and 7. The efficiency of earlier scores and Otis Lennon Mental Ability Test scores in predicting seventh-grade SAT math scores was examined and found to be weak. (SJL)

Responding to allegations about the effect of coaching on the Scholastic Aptitude Test (SAT) and its predictive validity ("Harvard Educational Review," May 1980), Jackson evaluates Slack and Porter's arguments and addresses the issues of the utility of SAT scores as admissions criteria and the alleged misrepresentation of negative…

The Bakke case is viewed as simply another reflection of elitist criteria which limit the success of minority groups in our society. The arguments brought forth by Bakke's lawyers are shown to support this position. (GC)

Characteristics of 11 Repgrid indices of cognitive structure, particularly Smith and Leach's hierarchical complexity index, are investigated among boys and girls, aged 9-15. The Smith & Leach index is shown to be significantly reliable; but in common with seven indices of cognitive differentiation, it is of dubious validity. (Author/GDC)

Investigates the psychometric properties of the Preschool and Primary Nowicki-Strickland Internal-External Control Scale (PPNS-IE). The test was administered to first, second and third graders. (CM)

For each of four subsamples of Olympic-quality athletes--14 discus, 8 hammer, 11 javelin, and 12 shotput measures of 19 personality constructs yielded only two statistically significant validity coefficients (out of 76 possible significant indices) in the prediction of average length of throw. (Author/JKS)

A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. (Author/CP)

High school males (N=66) and 60 high school females were tested for anxiety and vocational maturity levels. The experimental subjects were given the Self Directed Search (SDS). Statistical analysis indicated that the SDS was an effective instrument in reducing career indecision. (Author)

Assesses Ontario nursing student scores on the Nursing Comprehensive Examinations, and compares them with those from the Registered Nurse Exams. A positive correlation between the two examinations was found, suggesting that the comprehensive examinations predict success on the R.N. Exams. (YKH)

As part of a larger longitudinal study, scores of 239 children (ages 1 to 4) with disabilities on the Battelle Developmental Inventory (BDI) were compared with scores on the Woodcock-Johnson Test of Achievement (Revised) 1 to 3 years later. The BDI scores from children at or above age 2 predicted later achievement scores (mean correlation .74).…
