The authors investigated trends over a 13-year period in the predictive validity of assessment center data for objective career advancement for a sample of 456 academic graduates. Using year of entry and tenure as controls, findings from research into managerial effectiveness and development were confirmed with respect to the importance of…

We present an expository account of the development of the theory of binary quadratic forms. Beginning with the formulation and proof of the Two-Square Theorem, we show how the study of forms of the type x[squared] + ny[squared] led to the discovery of the Quadratic Reciprocity Law, and how this theorem, along with the concept of reduction relates…

Replication was undertaken of a recent study conducted by Buell and Anthony which had found that recidivism and posthospital employment could be predicted by a single demographic variable, number of previous hospitalizations and employment history, respectively. Results of the replication were consistent for posthospital employment but not for…

Although criteria for the diagnosis, prognosis, and treatment of Alzheimer's disease (AD) have become better defined, few research findings have appeared in the literature which characterize the degenerative course of the disease. Of particular interest to both clinicians and researchers would be a study focusing on changes in the patient's…

A sample of 640 children between 2.5 and 6 years old provided norms for scales of the Revised Gesell Preschool Examination. Scales focused on motor, adaptive, verbal, number, and personal and social development. A total of 272 children were reevaluated at 8.5 years on 22 variables derived from teacher ratings, parent questionnaires, and tests. The…

Recently there appears to have been an increase in interest in the relative power of general ability and narrower cognitive aptitudes to predict real world performance in training programs and on the job. This area has important practical implications for personnel selection and classification, particularly for large organizations such as the…

Traditional vocational appraisal, based primarily on the questionable predictive validity of tests, is reappraised; a new look for appraisal is proposed and integrated with a comprehensive approach to career counseling. (Author)

This followup to a previous study questioning the use of the Academic Achievement score on the SVIB to predict the academic achievement of women supports the earlier study's results. (HMV)

First grade children in Israel were tested on the Wechsler Preschool Primary Scale of Intelligence (WPPSI); most were retested using measures of Reading and Arithmetic. Intelligence and achievement test scores were correlated to provide estimates of the predictive validity of the WPPSI. The Israeli WPPSI was highly valid for predicting school…

The hypothesis was tested that subjects fake personality tests by enacting a specific social role, rather than by responding in terms of personality constructs, and that such role faking cannot be detected by validity scales. Results support the hypothesis. (Author)
