Results from a battery of 17 diverse tests completed by 877 white and 855 black students in grades 3 through 8 support Spearman's hypothesis that the white-black difference in test performance is predominantly a general intelligence ("g") difference rather than a unitary developmental difference affecting all factors in test performance.…

Focuses on the issue of intelligence testing within Scotland during the 1920's and 1930's. Addresses the reasons why Scotland delayed the use of intelligence tests for selection for secondary education, even though the conditions seemed to have been ideal for the adoption of intelligence testing.

The pioneering work of Leta Hollingworth (1886-1939) in using above-level testing with highly intellectually talented young people is recounted and related to contemporary activities of the Study of Mathematically Precocious Youth. (DB)

The Learning Disability Index (LDI) was validated by an examination for mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum was found to measure Third Factor strengths/weaknesses as much as verbal-performance…

Seven hierarchical clustering methods were applied to the Wechsler Adult Intelligence Scale-Revised (WAIS-R) scores of 121 medical rehabilitation clients to investigate the possibility of method-dependent results and determine the stability of the clusters. This multiple-methods cluster analysis suggests that the underlying constructs of the…

Explored sex differences on the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a sample of 432 Arkansas school children, ages 6 to 16, referred for special education assessment. Analysis of variance indicated significant sex differences among WISC-R Full Scale, Verbal, and…

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…

Research procedures used to evaluate the intelligence of children with specific language impairment are reviewed. Almost half of the 167 studies did not include adequate descriptions of intelligence assessment. (Author/JDD)

Problems and issues in measuring functional literacy are explored through an overview of definitional dilemmas, synopsis of widely known assessments, examination of the concept of ecological validity, and discussion of the impact of concepts of validity on the interpretation of functional literacy test performance. (SK)

The study examined the demographic distribution of 102 subjects with attention deficits in the Wechsler Intelligence Scale for Children-Revised standardization sample. Although neither age nor occupational status were significant, males and female residents of the West were overrepresented. (Author/DB)

Administered Kaufman Assessment Battery for Children (K-ABC) and Stanford-Binet Fourth Edition (Binet IV) to 32 gifted third- and fourth-graders. Binet IV scores averaged eight points higher than K-ABC scores. Concurrent validity coefficient of .70 indicated high degree of association between test performance on two tests. Results support use of…

Patterns of intelligence scale subtest scores and standardized achievement test scores of 80 gifted and 41 gifted learning-disabled students were compared. A distinctive cognitive pattern of intelligence test scores and patterns in group achievement test scores were identified to target students warranting more in-depth evaluation for early…

Use of the discrepancy approach in defining learning disabilities is challenged, as intelligence tests do not measure potential, are not independent from what is measured by achievement tests, and are not powerful predictors of low reading performance. Use of intelligence tests in analysis, identification, and definition of learning disabilities…

In commenting on Linda Siegel's argument (in EC221505) that Intelligence Quotient is not causally related to reading difficulties, this paper argues that Intelligence Quotient is relevant to the definition of reading disabilities but that present knowledge may not justify its use in the selection of children for special services. (JDD)

This response to Linda Siegel's paper (EC221505) suggests some alternative explanations of phonological processing as a basis for determining reading disability. Discussed are the use of pseudoword tests, the relationship between phonological coding and intelligence quotient, and the relationship between phonological coding and reading…
