Presents the drastic effects that selection on several variables can sometimes have on the validity of predictor variables. Discusses practical implications of correcting correlations for selection effects and reporting results of validity studies. (Author)

Compares, within the context of parole decision making, the predictive utility of five statistical methods commonly used to develop correctional risk-screening devices. Results suggest that no apparent empirical advantage accrues to any particular model. Further, most devices developed are highly intercorrelated. (Author)

Integrated schools, family income, and regional differences were not a factor in achievements of Black professionals. Most were educated by parents only and service rather than money was the basis of career choice. Those in helping professions should consider successful Blacks in developing a mental health model.

Economic factors serve to control the degree to which individual and work-related factors can explain variation in turnover. Individual and work-related variables will be more predictive of turnover under prosperous economic conditions than when the economy is strained. (Author)

Focuses on the consequences that the structural configuration of lexical knowledge has for the timecourse of parsing. Discusses reduced relative clauses and proposes a new lexical-structural analysis for manner of motion verbs. The article examines consequences for frequency-based models and all models whose difficulty derives from the ambiguity…

Counselor ratings and statistical data from client files were gathered for 71 rehabilitation clients. A Markov Chain model was developed which provided viable probabilities for predicting rehabilitation outcome at three time periods, from 1 to 13 weeks after initial interview. Predictions generally followed a time progression toward stronger and…

Tested predictive validity of stress-vulnerability model of suicide ideation and behavior. Undergraduates completed measures of social/emotional alienation, adaptive resources for living, and cognitive rigidity at beginning of semester. Measures of stress and cumulative negative life stress were obtained midterm. Found that combination of…

We develop a simple model of teacher behavior that offers a solution to the ''class size puzzle'' and is useful for analyzing the potential effects of the No Child Left Behind Act. When teachers must allocate limited classroom time between multiple instructional methods, rational teachers may respond to reductions in class size by reallocating…

Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…

Article based on a presentation given at a special commemorative session at the 1964 annual meeting of the American Psychological Association, Los Angeles

This study tests the basic assumptions underlying Fishbein's Model of Attitudes by correlating an individual's selective exposure to types of television programs (situation comedies, family drama, and action/adventure) with the attitudinal similarity between individual attitudes and attitudes characterized on the programs. Twenty-three college…

This study sought to develop and test a method for predicting inpatient utilization in the New York State Department of Mental Hygiene. A Markov chain mathematical model was developed and tested ex post facto for its accuracy in prediction of inpatient workload by age groups for two successive fiscal years. (Author)

The generalizability of the Fishbein model for behavior prediction was extended to a new field of behavior, alcohol drinking by adolescents. This research investigated the predictive importance of the model's two components, attitudes and normative beliefs. (Editor/RK)
