The predictive validity of the new Medical College Admission Test as it relates to end-of-quarter examinations in anatomy, histology, physiology, biochemistry, and "ages of man" is presented. Results indicate that the Science Knowledge assessment areas of chemistry and physics and the Science Problems subtest were most useful in…

Findings of this study argue against the existence of a separate diagnostic category of hyperactivity. Hyperactivity and conduct-problem scales should be combined for purposes of rating child behavior problems. A category of "attention deficit disorder without hyperactivity" should be considered as a separate rating scale factor.…

Results partially confirm the hypothesis that variations in collective bargaining agreements and major contract areas can be explained by the economic and institutional environments in which negotiations occur. (Author/IRT)

The extent to which the Group Embedded Figures Test (GEFT) measures aspects of personality and cognitive impairment was explored in 81 male alcoholics receiving treatment for alcoholism. Results suggest GEFT may be more a measure of cognitive impairment than personality. Alternative explanations are explored. (Author/RL)

Described is the use of two models of pocket calculators. The Hewlett-Packard HP67 and the Texas Instruments TI59, to solve problems arising in connection with ionic equilibria in solution. A three-parameter regression program is described and listed as a specific example, the hydrolysis of hexavalent uranium, is provided. (BT)

The socioeconomic status of a community is the strongest predictor of salary levels paid to teachers. Both community ability and effort are strongly affected by socioeconomic status factors, which in turn condition characteristics of teachers (experience and training levels) through staffing and salary policies of boards of education. (Author/IRT)

Contrasts aptitude by treatment interaction (ATI) and hierarchical linear modeling (HLM) methods for making cross-level inferences between individual-level and group-level factors in school effectiveness research. Recommends HLM when intraclass correlations are high. ATI is suitable when intraclass correlations are low, but partitioning the…

Investigates the pattern of predictors for male and female attitudes toward lesbians. The following significant predictors are investigated: (1) gender role attitudes; (2) parents' attitudes toward lesbians; (3) authoritarianism; and (4) education and media exposures. Sex differences in attitudes toward lesbians are discussed. (JS)

This study explores interrelationships among the following components of Erik Erikson's theory of ego identity formation: (1) the identity crisis; (2) the institutionalized moratoria; (3) the ego-superego struggle for dominance of the personality; and (4) the value orientation stages. Humanistically oriented adolescents are more likely to have a…

Bayesian and empirical Bayes approaches to shrinkage estimation of regression coefficients and uses of these in prediction (i.e., analyzing intelligence test data of children with learning problems) are investigated. The two methods are consistently better at predicting response variables than are either least squares or least absolute deviations.…

Discussion of teacher attitudes toward computer-assisted instruction (CAI) highlights a study that examined the relationship between Eysenck's personality factors (i.e., extraversion, neuroticism, and psychoticism), religiosity, and attitudes toward CAI in a sample of 190 female teacher trainees at Bar-Ilan University (Israel). (36 references)…

Examines two methods of differentially classifying language-delayed children as either specifically language impaired (SLI) or developmental-lag language impaired. Results indicated significant differences in classification between the two methods of defining SLI, as well as substantial changes in classification over time using either method. (47…

Analyzes structural factors affecting the cross-sectional variation in occupational differentiation between urban Blacks and Whites. Finds that the relative size of the Black population is the most powerful indicator of the level of occupational differentiation, but that educational level and the size of the urban population also had significant…

Tests of 172 fourth grade students in Zaria, Nigeria, supported the hypotheses that non-Western subjects' difficulties in judging depth in linear pictures are a function of individual perceptual organization, and that training could improve field independence and depth perception. Discusses child-rearing practices that may increase field…

Different approaches to defining suppression in multiple regression/correlation are compared, and their differences are illustrated. A test for determining the significance of a suppressor effect, which is based on the definition of suppression of W. F. Velicer, is extended to the general multiple predictor case and analysis of variance. (SLD)
