The theoretical differences between the traditional definition of dimensionality and the more recently defined notion of essential dimensionality are presented. Monte Carlo simulations are used to demonstrate the utility of W. F. Stout's procedure to assess the essential unidimensionality of the latent space underlying a set of terms. The…

This study employed a psychometric paradigm to explore how young people think about risk. Forty-one high school students were asked to rate 30 activities on 14 characteristics such as personal risk, perceived control over the risk, peer influence, etc. The study also included a questionnaire on actual participation in each of the 30 activities.…

This paper contends that school psychologists often are expected to reconcile, interpret, and evaluate the cognitive and behavioral functioning of children with neurologically related disorders. In this light, it is suggested that students in graduate programs in school psychology could benefit from specialized education and experience in applied…

Much of the scientific community has believed that temperament variables could not be included in batteries of tests to predict job performance because no generalized principles could be discerned from the results. For Project A, a major Army project on the prediction of job performance, a temperament inventory was developed and implemented. This…

There are two types of errors made in feeling-of-knowing (FOK) studies: a commission error occurs when a subject answers a question incorrectly, and an omission error occurs when a subject fails to provide an answer for a given question. A subject makes a commission error if he or she responds to the following question, "In which city does…

A class of multidimensional latent trait models is described. The properties of the model parameters, and initial results on the accuracy of a maximum likelihood procedure for estimating the model parameters are discussed. The model presented is a special case of the general model described by Rasch (1961), with close similarities to the models…

This paper addresses practical Army problems in reading assessment from a theory base reflecting the most recent research on reading comprehension. Military and occupational research shows that reading proficiency is related to job performance. Reading assessment is a key issue in the Army due to changes in the reading ability levels of the Army…

The practice of not sharing tests results with clients may soon be in conflict with the Ethical Standards for Psychologist (sic). Studies using self-validation of feedback information to study feedback parameters have shown that the form of feedback is less important than the content. To investigate direct feedback of test results by computer, the…

SCHOOL PSYCHOLOGY ENCOMPASSES ANY AREA OF GENERAL PSYCHOLOGY BROUGHT TO BEAR ON ANY PROBLEM OF SCHOOLS, OR PERSONS IN SCHOOLS, OR THE EDUCATIONAL PROBLEMS OF SCHOOLS. AFTER WORLD WAR II, THE DEMAND FOR SCHOOL PROVISION OF CLINICAL SERVICES ROSE GREATLY BECAUSE OF THE RECOGNITION OF NEED, AFFLUENCE, AND THE POST-WAR BABY BOOM WHICH MAGNIFIED…

THREE PSYCHOLOGICAL DISCIPLINES OFFER APPROACHES TO AN UNDERSTANDING OF INTELLIGENCE. AN ATTEMPT IS MADE TO UNCOVER THE COMMON FEATURES OF THE PSYCHOMETRIC SCHOOL, LEARNING, AND MENTAL DEVELOPMENT APPROACHES. A STRUCTURAL CONCEPT IS SELECTED FROM EACH PSYCHOLOGICAL DISCIPLINE FOR COMPARATIVE ANALYSIS--THE CONCEPT OF FACTOR FROM THE PSYCHOMETRIC…

FOUR COMMONLY USED INDIVIDUAL INTELLIGENCE TESTS ARE DESCRIBED. DESCRIPTIONS OF SUBTESTS ARE GIVEN, ALONG WITH EXPLANATION OF WHAT EACH TEST MEASURES. THIS INFORMATION IS PROVIDED TO ASSIST THE TEACHER IN IDENTIFYING SPECIFIC ABILITIES AND WEAKNESSES IN INDIVIDUAL CHILDREN. (JW)

CRITERION MEASURES DEVELOPED FOR ON-THE-JOB PERFORMANCE OF PHYSICIANS WILL BE USED IN A SUBSEQUENT STUDY TO DETERMINE HOW MUCH THE PERFORMANCE OF PHYSICIANS CAN BE PREDICTED BY THEIR INDIVIDUAL ACHIEVEMENTS IN MEDICAL AND PREMEDICAL SCHOOL. APPROXIMATELY 29 MEASURES OF THE UNIVERSITY OF UTAH COLLEGE OF MEDICINE AND OTHER PHYSICIANS IN THE UTAH…

Bargmann's test for examining the statistical significance of simple structure in factor analysis, an extension of the original significance tables, and the application of the significance test to several noted factor analytic findings are described. Using Bargmann's test, only 2 of 25 factor analytic studies reviewed are considered acceptable.…

The first of three parts of the Vocational Evaluation Project final report contains an editorial, two task force reports, and brief summaries of the seven task force reports which comprise the final report. The editorial summarizes the project's purpose, its activities for the three years of its existence, and its results, and describes the task…

Psychological testing as an area has perhaps evoked more controversy and heated emotion than has any other area within the fields of psychology and counseling. Part of the reason for this has to do with the inherent complexity and difficulty of the task of assessing human abilities, emotions and achievements. But beyond this basic issue, an…
