Kirby and Das (EJ 182 444) dichotomized measures of individual differences and treated them as independent variables in an analysis of variance. Correlational analysis would have provided more powerful tests of their hypotheses. Interpretation of the dichotomized variables as independent, causal antecedents of their measures of intelligence would…

The t ratio used in testing the difference between two independent regression coefficients is generalized to the multivariate case of testing the difference between two vectors of regression coefficients. This is particularly useful in determining which of two variables best predicts a number of criterion variables. (Author/JKS)

Scales from the Guilford-Zimmerman Temperament Survey and from the Thurstone Interest Schedule were correlated with achievement for students in a personnel evaluation course. Achievement was significantly correlated with the emotional stability and personal relations scales. (JKS)

The relationship between environmental ratings of community homes using factor scores derived from the Program Analysis of Service Systems and changes in adaptive behavior of 245 developmentally disabled residents living in those facilites was investigated. (Author/PHR)

Demonstrates how recalibration of education and occupation predictor variables relating to income attainment can improve accuracy with which income attainment is predicted. (Author/DB)

Tests indicated that kindergarten children with impulsive conceptual tempos performed significantly lower on several measures of achievement and reasoning ability than did children with reflective tempos. (Editor)

Seven easily obtainable background variables, such as number of persons, rooms, or cars per family dwelling; kindergarten attendance; and sex were found to have a multiple correlation of .52 with a standard achievement test for a large sample of fourth grade pupils in a metropolitan school district. (JKS)

This paper evaluates and tests several theories of middle class delinquency. Arguments that middle-class boys are less delinquent and commit different kinds of delinquent acts than boys from other classes are not supported by the data. A modified version of social control theory is tested. (Author/AM)

Sixty children were individually administered the Matching Familiar Figures Test and the Bender Gestalt Test. A significant relationship was found between errors on the Bender Gestalt Test and impulsivity. Specifically, increased or decreased loops, change in angulation, loops for circles, and circles for dots or dots for circles were all…

This study compared three models for predicting altruistic behavior. The helping behavior (donating blood) of 251 undergraduate students was examined as a function of intention (model I), norms and ascription of responsibility (model II), and attitudes and self-monitoring (model III). (CM)

In order to determine whether counselor self-disclosure was predictive of counselor self assertion, a regression model containing 15 predictor variables was utilized. Results showed that self-disclosure may assist individuals in asserting themselves, and that it accounts for almost half of the variance within assertive behavior. (Author/MV)

This study involved the determination of the relationship between each of 15 predictor variables (primarily reflecting cognitive abilities and study skills) and each of 13 criterion measures representing course grades and scores on the National League for Nursing Achievement Tests. (Author/RC)

A predictive equation for estimating performance in a basic course in methods of psychological research from scores on the Differential Aptitude Test reasoning scales and on the Davis Reading Test, from measures of attitudes toward issues in psychology, and from self-ratings of abilities and of expected course grades is developed. (Author/DEP)

Expressed vocational choices were more predictive of employment status four years after high school graduation for males than were scores on either the Vocational Preference Inventory or the Kuder Preference Record--Vocational. Predictions for males were more accurate than for females on all measures. (Author)

Possible respondents in a 1974 survey of University of Kentucky doctoral graduates were sent either computer-prepared or offset-printed questionnaires, personalized and identical in content. Overall response rates were similar except when the responses were categorized by the academic major of each recipient. (Editor/LBH)
