Variables that affect the deductive reasoning of adult students are isolated and relevant literature reviewed in order to facilitate the design of a reliable measurement instrument. The relationships of previous instruction, cultural background, occupation, intelligence, sex, and reasoning habits to test scores of examinees are discussed. Studies…

The relationship between variations in an auditory signal identification task and consequent changes in the abilities related to identification performance was investigated. Characteristics of the signal identification task were manipulated by varying signal duration and signal-to-noise ratio. Subjects received a battery of reference ability tests…

The relationship between the factor structure of a convariance matrix and the factor structure of a partial convariance matrix when one or more variables are partialled out of the original matrix is given in this brief note. (JKS)

The factor differentiation hypothesis suggests that the factor structure of a set of tests tends to differentiate over time, becoming more complex and articulated. This experimental study provides evidence confirming that hypothesis. (Author/JKS)

Investigated factor structures of Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) for 212 normal children. Findings suggest correspondence between: (1) WISC-R Verbal Comprehension and K-ABC Achievement; (2) WISC-R Perceptual Organization and K-ABC Simultaneous Processing; and (3) WISC-R…

Examination of factors derived from responses to the Facts on Aging Quiz were found to be different from those determined intuitively by Facts on Aging Quiz's author Palmore. Found reliability and validity of scale to be moderate and recommended Facts on Aging Quiz be used for only educational and not research purposes. (Author/ABL)

Research on the semantic differential technique has provided evidence for variance in Osgood's formulation of dimensions of connotative meaning. Retest data based on Piotrowski's original sample is reported. Results indicate support for stability and consistency of the Evaluation dimension. Moderate consistency was found in scales comprising the…

Cross-validated the factor structure of the McCarthy Scales of Children's Abilities for 105 kindergarten children. A factor analysis generated five factors, including Verbal Comprehension, Quantitative-Reasoning, Memory, Perceptual-Performance, and Motor factors. The overall factor pattern provides further evidence of the construct validity of the…

Replicated a recent report of the factorial structure of the Multidimensional Health Locus of Control Scale, using rehabilitation patients. Analyses failed to validate the previously reported three-dimensional structure, which indicates a need for careful interpretation of this scale when used with certain populations. An alternative factor…

The vocational interests of disabled adults can be differentiated and are structured in a way that corresponds closely with the interest dimensions of other populations. The United States Employment Service Interest Inventory (USES-II) is recommended for vocational rehabilitation counseling with disabled adults. (Author/ABB)

Reviews WISC-R factor analytic findings for developing a scheme for regrouping WISC-R subtests, consisting of verbal comprehension and spatial subtests. Subtests comprising these groupings are shown to have more common variance than specific variance and cluster together consistently across the samples of WISC-R scores. (Author/JAC)

Examines the structure of human abilities from a hierarchial viewpoint. Findings provided a description of the abilities that children may use in responding to the tasks included in the Wechsler Intelligence Scale for Children-Revised and provided a framework to generate clinical hypotheses about any child's performance. (LLL)

Factor-analyzed the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) scores of emotionally disturbed children (N=181). The results suggested that the structure of intelligence for emotionally disturbed children is similar to that for normal children. WPPSI profile analysis that uses subtest scores may be invalid in clinical settings.…

A factor validity study of the Learning Style Profile (LSP) developed by the National Association of Secondary School Principals was conducted. Developed for use with students in grades 6 through 12, the Profile, which consists of 26 questions representing 24 independent subscales, requires approximately 60 minutes to finish. A random sample of…

The twofold purpose of this study was to investigate the reliability and construct validity of scores on the Japanese version of an academic self-concept scale titled the Dimensions of Self-Concept (DOSC) Form H and ascertain any relationships between scores on the DOSC scale and selected demographic variables, including class, gender, and…
