Three measures of person-fit (the extent to which an examinee's response pattern on a multiple-choice test is consistent with his ability as estimated by total score) were computed for students taking classroom tests under 12 different instructors at a comprehensive university. Supplementary questions on each test inquired concerning students'…

A study assessed the predictive validity of two substantially different instruments (a questionnaire or a philosophy statement) which may be used to predict critics' ballot behavior in Cross Examination Debate Association (CEDA) debate. Questionnaires were distributed to 29 debate tournaments across the United States for completion by critics…

A statistical model for investigating predictive validity at highly selective institutions is described. When the selection ratio is small, one must typically deal with a data set containing relatively large amounts of missing data on both criterion and predictor variables. Standard statistical approaches are based on the strong assumption that…

Psychologists and psychiatrists are regularly used during civil commitment and other hearings to prognosticate dangerousness for the courts. In this process, the judiciary has shown almost complete deference to the recommendations of forensic specialists despite a number of early studies that did not support a clinician's ability to predict…

The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of…

Quality of performance data yielded by subjective judgment is of major concern to researchers in performance appraisal. However, some confusion exists in the analysis of quality on ratings obtained from different rating scale formats and from different raters. To clarify this confusion, a study was conducted to assess the quality of judgmental…

Four studies were conducted to investigate the relationship between communication and predictive accuracy. Subjects, students enrolled in various college speech and communication classes, completed the Allport-Vernon-Lindzey Study of Values, first in terms of their own values and then in terms of how they believed a specified target would respond.…

Of the many short forms of the Minnesota Multiphasic Personality Inventory (MMPI) that have been developed, the MMPI-168 is among the most promising. To determine whether clinical judgments based on the MMPI-168 are comparable to judgments based on the standard MMPI, 30 clinical psychologists participated in a randomized block, repeated treatment…

Considerable research has examined the correlates of job involvement and its conceptual independence from the notions of satisfaction and motivation, with an indication of considerable overlap beween the three concepts as well as the possibility that job involvement may be more aligned with motivation than with satisfaction. A job attitude survey…

Discriminant analysis of Holland's Self Directed Search and Vocational Preference Inventory significantly improved the predictive validity of his classification scheme, over the traditional method of assigning high point codes. These results were obtained with both an initial and a replication sample of undergraduates pursuing various degrees. The…

According to Fiedler's Contingency Model of Leadership Effectiveness, group performance is a function of the leader-situation interaction. A review of past validations has found several problems associated with the model. Meta-analytic techniques were applied to the Contingency Model in order to assess the validation evidence quantitatively. The…

This study investigated several levels of internal and external disequilibrium and their interaction. Subjects were 63 fifth graders assigned to three groups according to their degree of internal disequilibrium. Internal disequilibrium was measured by the amount "level mixture" (a tendency to respond to various events at several…

The common approach to studies of predictive bias is analyzed within the context of a conceptual model in which predictors and criterion measures are viewed as fallible indicators of idealized qualifications. (Author/PN)

The merits of double exponential smoothing are discussed relative to other types of pattern-based enrollment forecasting methods. The basic assumptions and formulas for its use are outlined. The difficulties associated with selecting an appropriate weight factor are discussed, and the potential effect on prediction results is illustrated.…

A study created and examined a new communication trait--the willingness to collaborate. The Willingness to Collaborate Trait Scale was created. Scale reliability was demonstrated through analysis of internal consistency of the 13-item scale. A communication trait model predictive of trait willingness to collaborate was tested using 401…
