This paper addresses the problem of heterogeneity of samples of learning disabled (LD) children by comparing five different systems for identifying homogeneous subgroups in terms of their ability to predict longitudinal reading and mathematics scores. One hundred and sixty LD children served as subjects. Three of the five subgrouping systems were…

Evaluation of mean score differences between the Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Intelligence Scale for Children (Revised) (WISC-R) for 126 children with academic difficulties found the Stanford-Binet composite score was significantly higher than the WISC-R score at the lower end of the ability continuum but…

The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

The stability of intelligence test scores over time was examined for the Wechsler Intelligence Scale for Children-Revised (WISC-R). Subjects included 64 children aged 6-16, who had been administered the WISC-R during prior evaluations. These students had been referred because of academic difficulties. One-third of the sample had taken the test…

A study of 33 elementary/middle school deaf children correlated Wechsler Intelligence Scale for Children-Revised Performance Intelligence Quotients (IQs) with Stanford Achievement Test-Hearing Impaired Edition (SAT-HI) grade equivalents and age-based percentiles. A second study of 64 children correlated nonverbal IQs from many tests with SAT-HI…

This book is intended to assist in using the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) and the Wechsler Intelligence Scale for Children-Third Edition as tools for identifying a child's strengths and weaknesses for the purpose of improving academic and behavioral functioning. The first chapter focuses on using the…

The Wechsler Intelligence Scale for Children-Revised (WISC-R), one of the most commonly used tests of cognitive ability, is difficult to administer accurately. The purpose of this study was primarily to assess interrater agreement on the WISC-R Administration Observational Checklist (WAOC), a new observational instrument that can be used by an…

The study investigated cultural bias in the verbal items of the Wechsler Intelligence Scale for Children-Revised (WISC-R). Six verbal subtests of the WISC-R were administered to 40 Anglo, 40 Mexican-American, and 40 Navajo intermediate grade students matched for grade level, sex, and socioeconomic status. The responses of three groups of subjects…

To examine the validity of short forms of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the WISC-R was first administered to 106 hospitalized psychiatric patients, aged 8-16. No subjects had a primary diagnosis of mental retardation or learning disability, and one-third were receiving psychotropic medication. WISC-R IQ scores…

This study examined whether Wechsler Intelligence Scale for Children (Revised) subtest patterns employing Kaufman's classification system differ between male and female elementary grade students receiving special education services. It also examined whether females in special education are more significantly impaired than males, and whether males…

Normal black adolescents were given neuropsychological tests of brain damage, and the interpretation of these tests was reviewed with respect to culturally relevant data. Subjects were 50 male and 50 female black students, aged 12-13, with no history of central nervous system trauma, and average scores on the Wechsler Intelligence Scale for…
