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.

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…

This response to a paper by Linda Siegel (EC221505) on the relationship between Intelligence Quotient and learning disabilities addresses the differences between classification and identification, limitations in Siegel's conceptualization of intelligence, and the representation of the language and learning domains subsumed within the learning…

This paper reviews the advantages and disadvantages of testing for giftedness, the repercussions of testing and not testing, issues concerning intelligence quotients, and the effects of labeling children. (JDD)

Critiques ideas expressed by Gould in "The Mismeasure of Man." Agrees with Gould that many scientists who studied human intelligence were racist, but disagrees that their work must therefore necessarily be dismissed. Disputes Gould's claim that factor analysts who study human intelligence have reified their factors and that factor…

The Stanford-Binet IV is compared to the original version and criticized for having less power to measure the high end of intelligence and for having norms that discriminate against gifted students. Strengths of the Stanford-Binet L-M are pointed out, and use of both scales for different purposes is recommended. (JDD)

This article offers advice on interpreting intelligence quotient (IQ) data and other results from intelligence tests. Myths regarding the practical applications and broader implications of IQ profiles are debunked. Several warnings are given regarding test use along with general statements of intelligence tests' strengths and weaknesses in…

A table is provided for determining the frequency of occurrence of Verbal-Performance discrepancies on the Wechsler Intelligence Scale for Children-Revised (WISC-R) in profiles of high Intelligence Quotient children. Warnings are offered regarding the adverse effect of subtest substitution or omission when administering the WISC-R to highly…

This response to Detterman and Thompson (1997) analyzes their criticisms of special education and presents evidence of the effectiveness of current instructional techniques for children with disabilities in contrast with the cognitive approaches favored by Detterman and Thompson. Assumptions about the significance of intelligence testing and…

Considers how IQ tests may not be an effective means of identifying English-as-a-second language (ESL) students with learning disabilities due to inherent cultural biases of the tests. Concludes that the use of IQ tests with ESL or English-dialect students is inappropriate when the student's first or primary language is different from the language…

Age differences within the yo-yo trend in IQ, caused when aging norms that produce inflated scores are replaced with new norms, were examined using longitudinal WISC, WISC-R and WISC-III records of students tested for special education services from 10 school districts. Descriptive and individual growth modeling analyses revealed that while the…

We evaluated the predictive accuracy of short forms of the Wechsler intelligence scales for individuals with high functioning autism. Several short forms were derived from participants who had received the full procedure. Stepwise multiple regression analyses were performed to determine the strength of association between the subtests included in…

Spearman's hypothesis states that the differences between Blacks and Whites in psychometric IQ are attributable to a fundamental difference in general intelligence ("g"). To investigate this hypothesis, Jensen devised the method of correlated vectors. This method involves calculating the correlation between the factor loadings of the…

This research studied the interchangeability of individually administered and group administered cognitive tests. Seventy undergraduate students took the Hebrew version of the WAIS-R (Wechsler Adult Intelligence Scale-Revised), and their IQs were measured. They also took the IPET (Israeli Psychometric Entrance Test) and their IPET scores were…
