Employing a computer-controlled experimental paradigm for studying coalition formation and bargaining, the present study tests three models for n-person games in characteristic function form, namely, the bargaining set and two of its subsets, the competitive bargaining set and the kernel. Twelve groups of subjects participated in several four…

Recent research on the behavioral assessment and treatment of social anxiety and inhibition is reviewed. Subjects for the studies were college men and women selected on the basis of heterosexual anxiety and inhibition. The first part of the paper is concerned with assessment. The behavioral assessment procedures developed include: (1) direct…

To analyze selected demographic and psychometric characteristics of dropouts and graduates from vocational training at a comprehensive rehabilitation center, nearly 600 dropouts and graduates of the Pennsylvania Rehabilitation Center were studied. Five variables were found to be useful in predicting dropouts: (1) preselected training goal upon…

A simple, rigorous, small-sample statistical technique is described for testing the hypothesis that two sets of measurements differ only because of errors of measurement and because of differing origins and units of measurement. (Author)

This paper emphasizes the need to go beyond structural models of personality and intellect to develop sequential models of psychological process, particularly for such complex phenomena of prime concern to theory and application as learning, problem solving, and creativity. It is further argued that factor analysis, in a multitude of studies of…

Although it has been claimed that the Rasch model leads to a higher degree of objectivity in measurement than has been previously possible, this model has had little impact on test development. Population-invariant item and ability calibrations along with the statistical equivalency of any two item subsets are supposedly possible if the item pool…

The contribution of a 20-minute essay question, given as part of the one-hour achievement test in American History and Social Studies, to the pool of information available on a candidate from an all-objective examination of the College Board Admissions Testing Program is presented in this report. The study limits itself to a consideration of the…

This research was undertaken to determine the factor structure of the 26-item revised versions of the Mehrabian (1968) Female and Male scales, a self-report instrument designed to measure achievement motivation. (Author/RK)

A pair of related experiments examined the psychometric properties on the Threat Index (TI), a theoretically based scale for the assessment of threat of death. The high reliability of the TI suggested its functioning as an index of stable conceptual orientation toward death. (Author)

Timed performance measures from a coincidence timing task taking about 10 minutes are shown to have significant correlations with psychometric general intelligence in a group of 56 children. The mean absolute error across three conditions correlated -.294 with Raven's Standard Progressive Matrices scores but was sex-biased, with girls being less…

Psychometricians working in factor analysis and econometricians working in regression with measurement error in all variables are both interested in the rank of dispersion matrices under variation of diagonal elements. This paper reviews both fields; points out various small errors; and presents a methodological comparision of factor analysis and…

Psychometric characteristics of the test scores of 5,663 examinees on six patient management problem tests were studied. The total scores can be divided into subscores based on all options keyed "select" and "omit." Component scores are generally correlated negatively, as reflected in reduced discrimination indices and…

The reviewer praises the book as a good elementary introduction to theory and method in factor analysis as it applies to psychometrics and social science research. (TJH)

An approximate relationship is devised between the unidimensional model used in data analysis and a multidimensional model hypothesized to be generating the item responses. Scale shrinkage is successfully predicted for several sets of simulated data. (Author/LMO)

This study investigated whether measures of habituation and dishabituation in early infancy predicted later intelligence. Results were compared with those from other comparable studies. It was argued that the psychometric acceptability of infant cognitive measures needs to be demonstrated before they can be considered to be potential predictors.…
