This study examined the predictive validity of the Developing Cognitive Abilities Test (DCAT), a test similar in form to traditional intelligence tests but developed along a format that included both a cognitive taxonomy and content areas. Students in fourth through twelfth grades were administered the DCAT and the Achievement Series Test.…

For 271 middle-class tenth and eleventh graders, exploratory and confirmatory factor analyses were conducted on a correlation matrices of 90 items and 18 subtests, each containing five items. The Study Attitudes and Methods Survey was used. Via a multidimensional affective measure with homogeneous scales, both techniques yielded a high degree of…

Two studies were conducted to investigate the degree to which occupational stress among teachers could be attributed to personal characteristics of the individuals themselves. The first study developed dispositional stress scales. The second examined correlations between these scales, occupational stress scales, and teachers' attitudes toward…

Intercorrelations of 10 successive years of measurement of height and intelligence are presented for separate samples of girls and boys from the Harvard Growth Study. Findings did not differ appreciably by sex, but significant differences between the sexes in the cross-correlations were found. (Author/RH)

This article evaluated criticisms by Stevens and Aleamoni (1986) of an article by Gardner and Erdle (1984) on aggregation using either raw or standard scores. It was demonstrated that their criticisms were unfounded. (Author)

Three methods of transforming unordered categorical response variables are described: (1) analysis using dummy variables; (2) eigenanalysis of frequency patterns scaled relative to within-groups variance; (3) categorical variables analyzed separately with scale values generated so that the grouping variable and the categorical variable are…

In the family of correlation suggested by Janson and Vegilius, some coefficients are generalized squared product-moment correlations and some are not. This paper advocates a family of correlations for variables of mixed scale types in which all members are generalized squared product-moment correlations. Practical advantages are explained.…

The use of U-statistics based on rank correlation coefficients in estimating the strength of concordance among a group of rankers is examined for cases where the null hypothesis of random rankings is not tenable. (Author/BW)

A computer program randomly sampled ordered pairs of scores from known populations that departed from bivariate normal form and calculated correlation coefficients from sample values. Hypotheses were tested (1) that population correlations are zero using the t statistic; and (2) that population correlations have non-zero values using the r to z…

An analytic procedure is presented for testing the homogeneity of unstandardized regression weight vectors when the vectors are correlated. The basic design involves repeated measurements on a dependent variable and a set of independent variables. The method is illustrated with a study of perceived leader behavior. (Author/BW)

Describes a study which examined the relationship between learner chatacteristics and achievement in French as a second language. Results indicate that subjects who have more schooling, a higher degree of nonverbal reasoning ability, and make greater use of French outside the classroom are more likely to benefit from formal language instruction.…

This study explored relationships among elementary students' cognitive styles, Logo programing, academic achievement, and cognitive abilities. It was found that top-down processing as measured by a writing activity is positively related to Logo programing success, field independence, holistic tendencies, and general academic achievement. LOGO…

Two samples of adult subjects of reasonably average intelligence were given IQ tests and a series of reaction time tests using 0, 1, 2, and 3 lists of information in a Hick paradigm. (Author/LMO)

This study compared the test-retest reliability of the Southern California Sensory Integration Tests and the Luria-Nebraska Neuropsychological Battery--Children's Version. Both sets were administered twice to a group of 30 dysfunctional eight-year-old children. Findings are discussed in relation to reliability coefficients for normal as well as…

Factor and cluster analyses are distinctly different multivariate procedures with different goals. However, when used in a complementary fashion, each set of methods can be used to enhance the interpretation of results found in the other set of methods. Simple examples illustrating the joint use of the methods are provided. (Author)
