This meta-analysis examined the validity of an alternative to traditional assessments called the Wonderlic which is a brief measure of general mental ability. Our results showed significant, positive correlations between Wonderlic scores and academic performance in general ([r-bar] = 0.26), between Wonderlic scores and undergraduate GPA in…

The least squares distance method (LSDM) was used in a cognitive diagnostic analysis of TIMSS (Trends in International Mathematics and Science Study) items administered to 4,498 8th-grade students from seven geographical regions of Turkey, extending analysis of attributes from content to process and skill attributes. Logit item positions were…

The broad cognitive abilities defined by the Cattell-Horn-Carroll (CHC) theory have been shown to predict school achievement. However, the ecological validity of these constructs has not been studied in classroom settings. This study compares ratings by a sample of teachers (n = 53) and school psychologists (n = 86) of the importance of the CHC…

Purpose: The purpose of this report is to evaluate the reliability and validity of the five-item Evaluation to Sign Consent (ESC), a measure that can guide determination of an older adult's capacity to consent for research. Design and Methods: Information was obtained from 346 nursing home residents from six facilities who were being enrolled into…

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…

Performed confirmatory factor analyses of Kaufman Assessment Battery for Children (K-ABC) using subtest correlations for standardization samples provided in manuals to test hypothesis that factors underlying K-ABC are substantially intercorrelated at all age levels for two- and three-factor models. Findings suggest K-ABC cannot distinguish between…

A battery of nine cognitive abilities tests to assess verbal, spatial, perceptual speed, and memory abilities in children at age four was constructed and administered to a sample of 267 children in the Colorado Adoption Project. Exploratory and confirmatory factor analyses revealed four correlated factors that adequately describe the covariation…

Administered the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) to educable mentally retarded children (N=30). Results showed significant mean differences between WISC-R and WJTCA full-scale standard scores, providing implications for placement of children in classes for the…

Three new tests presented as alternatives to the Wechsler tests for children were described in earlier papers of this session. This discussion reviews the earlier papers and comments on the developed tests: (1) the Woodcock-Johnson test; (2) the new Stanford-Binet; and (3) the K-ABC. The Woodcock-Johnson battery, state-of-the-art applications of…

Examined and compared the validity of Friedman's Developmental Level (DL) and Exner's Developmental Quality (DQ) as measures of cognitive development in children (N=134). Results supported the convergent and discriminant validity of both DL and DQ. The DL and DQ were most strongly related to different types of cognitive ability. (JAC)

This study involving 30 college students with learning disabilities and 30 students without learning disabilities (ages 18-30) compared results obtained on the Wechsler Adult Intelligence Scale-Revised and the Kaufman Adolescent and Adult Intelligence Test. Results found no significant differences between the two groups or between tests.…

Reviews research on ability testing for adults with visual impairments, especially the tests used for vocational assessment and counseling. The verbal scales of the Wechsler Adult Intelligence Scale-Revised were found to be widely accepted. The problems, however, with relying solely on verbal assessment are addressed, and the need for tests for…

Reviews several research studies helpful for further examining Piaget's ideas and their applicability to physics teaching. Indicates that care must be taken with devices designed to measure cognitive ability. (Author/SK)

Validated a parent-based assessment of cognitive abilities of 3-year-olds, the Parent Report of Children's Abilities for 3s (PARCA3), against a standard tester-administered measure, the McCarthy Scales of Children's Abilities, and a vocabulary checklist. Found that PARCA3 parent report and parent-administered components significantly related to…

The primary goal of this review is to acquaint developmental psychologists who have had little experience in the study of individual differences in cognition with some of the basic rules that govern this type of research. A second goal is to stimulate researchers to consider the potential benefits of studying differences among individuals whose…
