Predicting occurrences of violent behavior in the population of emotionally disturbed criminal offenders was investigated by identifying a pattern of characteristics that significantly discriminates between violent and nonviolent offenders. Subjects were 149 current and former male patients in the Forensics Division of St. Elizabeths Hospital in…

A U.S. Air Force study was designed to investigate simultaneously four cognitive styles--field dependence-independence, reflectivity-impulsivity, leveling-sharpening, and visual-haptics. A sample of 206 undergraduate volunteers at the University of Oklahoma were tested with the Successive Perceptual Test I (SPT-I), the Hidden Figures Test (HFT),…

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…

Data from the 1970 census indicated that Blacks in low percentage Black neighborhoods had higher incomes, a greater probability of working wives, and higher educational levels than those in high percentage Black neighborhoods. Discriminant analysis suggested that social psychological factors may mediate demographic factors in Blacks' decisions to…

Multiple group discriminant analysis was employed to determine the utility of preenrollment traits and academic performance in identifying freshman students who persisted, stopped out, or withdrew early. After first-quarter academic performance, relatively clear distinctions can be made between students who persist and those who do not.…

Of 115 adult literacy students interviewed, 59 were contacted 8 months later to collect data on characteristics, academic and social integration, program and goal commitment, and withdrawal decisions. Factor and discriminant analyses identified 14 variables that accurately predicted the present status of 76 percent of completers, persisters, and…

A multivariate approach reexamined Lewis Terman's longitudinal study data comparing the 100 most successful and 100 least successful men identified in the 1920s as having very high intelligence. Results reaffirmed the importance of educational attainment in vocational achievement, though intelligence and amount of early acceleration also predicted…

The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model. Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting.…

The Basic Interest Scales (BISs) of the Strong Interest Inventory (SII; Harmon, Hansen, Borgen, & Hammer, 1994) have a 35-year history. The BISs are the specific content scales of the SII, as opposed to the SII general content scales, the General Occupational Themes (GOTs), which measure the six Holland (1997) RIASEC themes. Using 17,074…

This study tested the convergent and discriminant validity between two theories of college persistence: the Student Attrition Model and the Student Integration Model. The study examined conceptual similarities for each theory to explain departure decisions and examined how both theoretical frameworks enhanced the understanding of the processes…

A survey instrument containing 46 socioeconomic and attitudinal items was administered to a sample of 452 registered voters in the Columbia (Missouri) School District. Three past financial elections and two hypothetical future financial elections were chosen in order to describe and analyze the relationships between socioeconomic and attitudinal…

This paper is concerned with the identification and testing of salient variables which show potential for explaining client use of evaluation information. A single-page interview instrument was devised which aggregated the factors and factor categories collected following an extensive review of the literature. Data were collected from a…

A study using discriminant analysis to correct bias in predicting faculty rank is reported. Findings concerning the relationship of prediction error and gender and suggestions for use of the results to study salary-bias problems are also discussed. (Author/MSE)

Study compared teachers contemplating quitting the profession with teachers planning to continue. Subjects completed surveys which assessed work-related attitudes, perceptions, and reaction to work environment conditions. Results indicate that teachers who plan to quit or remain can be reliably distinguished by patterns of work-related attitudes,…

This study replicated previous research that tested the validity of A. Biglan's classification scheme, a theoretical framework for empirically examining the differences among academic disciplines and classifying them according to three dimensions (hard-soft, pure-applied, life-nonlife). In addition, new data were used to attempt continued…
