PDF on ERIC Download full text
Bulut, Okan; Cormier, Damien C.; Aquilina, Alexandra M.; Bulut, Hatice C. – Journal of Intelligence, 2021
The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) is a comprehensive assessment battery designed to assess broad and narrow cognitive abilities, as defined by the Cattell-Horn-Carroll (CHC) theory of intelligence. Previous studies examined the invariance of the WJ assessments across sex and age groups using factor analytic methods.…

What Can the WISC-R Measure?
Peer reviewed Peer reviewed
Conger, Anthony J.; And Others – Applied Psychological Measurement, 1979
The WISC-R was investigated by using measures of profile (multivariate) reliability to determine its most reliable dimensions and the precision and similarity of the multivariate structure across age groups. The structure of the WISC-R subscales was stable across age groups. Two strategies for the interpretation of WISC-R profiles are offered.…

WISC Performance Scale and Coloured Progressive Matrices With Deaf Children.
Peer reviewed Peer reviewed
Evans, L. – British Journal of Educational Psychology, 1980
When administered to 125 deaf youngsters, ages 5-12, the WISC performance test had good reliability and predictive validity, but administration to some young or physically handicapped children proved difficult. The Colored Progressive Matrices proved satisfactory with older subjects, but its suitability for younger deaf children was not confirmed.…

Reliability of WISC-III Subtest Composites.
Peer reviewed Peer reviewed
Siegel, Don J.; Piotrowski, Richard J. – Assessment, 1994
Reliability of subtest composites corresponding to 46 abilities and influences presented by Kaufman (1979) was examined for the Wechsler Intelligence Scale for Children using standardization sample data (ages 6, 11, and 16). Increasing composite reliability was associated with the number of subtests and inclusion of Verbal Scale subtests in the…

A Longitudinal Investigation of the Intellectual Differentiation Hypothesis
Peer reviewed Peer reviewed
Osborne, R. T.; Suddick, D. E. – Journal of Genetic Psychology, 1972
The mental growth patterns of 204 children were investigated on four different test occasions covering a five-year period, ages six to 11. There is no evidence of intellectual differentiation after age six nor is there a systematic decline in size of WISC subtest intercorrelations with increasing age. (Authors)

WISC-III Short Forms: Psychometric Properties vs. Clinical Relevance vs. Practical Utility.
PDF on ERIC Download full text
Kaufman, Alan S.; And Others – 1994
The reliability and validity of three short forms of the Wechsler Intelligence Scale for Children III (WISC-III) were compared. Each of the short forms was a tetrad composed of two verbal and two performance subtests. The first tetrad was selected based primarily on practical considerations, particularly its brevity to administer and score. The…
