A Scheme For Conducting Two-Sample Profile Analysis.

A scheme for conducting two-sample profile analysis with Hotelling's T[SUP2] tests and univariate t tests is described. Formulas are provided and a decision tree is presented to guide users in selecting among the tests. Two example problems are worked to illustrate the analysis. The procedure evaluates virtually the same hypotheses as two-factor analysis of variance designs that have a repeated measures factor. However, the procedure has less restrictive assumptions than do repeated measures designs.

The WISC-R factor score profiles of cultural-familial mentally retarded and nonretarded youth.

Factor scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) were compared for two groups of cultural-familial mentally retarded youth and one group of nonretarded youth. The younger retarded group had a mean CA of 9.5 years; the older retarded group has a mean WISC-R MA of 9.5 years, and the nonretarded group had a mean WISC-R MA and a mean CA of 9.5 years. No significant difference was detected between the retarded and nonretarded groups in their patterns of intellectual strengths and weakness. This finding was consistent with an expectation of the developmental viewpoint of retardation but contrary to a prediction of the difference theory of retardation. Differences were found between the retarded groups in their intellectual strengths and weakness. The older retarded subjects exhibited a relative strength in perceptual organization abilities, whereas the younger ones demonstrated no pattern of comparative strengths and weaknesses.

WISC-R Verbal Performance IQ discrepancies among quay-classified adolescent male delinquents.

Wechsler Verbal-Performance IQ discrepancies have been associated with the broad classification of delinquency, but not with a specific criterion of acting out or psychopathic adjustment. Accordingly, this study examined the hypothesis that the WISC- R Verbal-Performance IQ discrepancy would be larger or more frequent for persons classified as exhibiting a psychopathic delinquent adjustment than for persons classified as either neurotic or subculturally delinquent. Within-subject differences on intellectual measures were obtained for both the psychopathic and subcultural, but not the neurotic, delinquent adjustment classification. This result indicated consistency of intellectual asymmetry across behaviorally diverse delinquent subgroups. No between-group differences were obtained. The results were interpreted as affirming a reliable intraindividual intellectual asymmetry which provides a foundation to model and test hypotheses relating intellectual processes and delinquent behavior.
