Stanford Binet: Fourth Edition (SB:IV) assessments have been collected longitudinally for 195 individuals with Down syndrome. This article discusses individual assessments which were selected for their ability to highlight major concerns that practitioners need to consider when interpreting intelligence test scores with this population. In this…

This response argues that Linda Siegel's paper (EC221505) confuses measures of intelligence with predicted achievement, calls for doing away with the construct of learning disabilities rather than the discrepancy definition model, and overlooks the need to determine which students qualify for special educational services for treatment of learning…

This critique of a paper by Linda Siegel (EC221505) challenges Siegel's assumptions on the relationship of Intelligence Quotient to learning disabilities as being unacceptable and non-literature-based, and points out that discussion of Intelligence Quotient cutoffs may be moot given that 49 states employ no cutoff for learning disabilities. (JDD)

Discuss seven basic intellectual competencies possessed by all human beings: linguistic, logical-mathematical, musical, spatial, bodily-kinesthetic, interpersonal, and intrapersonal. Because I.Q. tests can measure only the first two qualities, this interview suggests evaluating schools by quality of educational experiences and students by project…

This commentary supports Linda Siegel's challenge to the learning disabilities field (in EC221505) to produce data indicating that dyslexic readers differ from other poor readers in their cognitive processing, educational prognosis, and response to treatment. The commentary also points out that the existence of Matthew effects reinforces Siegel's…

This paper reviews Lev Vygotsky's theories concerning optimizing of potential through assistance, support, or instruction. The paper notes that there is a "zone of proximal development" or a band around intelligence quotient (IQ) scores reflecting one's true potential. IQ tests are generally well-standardized and "static,"…

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…

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…

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 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…

Discusses differential and information processing theories of intelligence and the problems of measuring intelligence. Considers the influence of sociocultural factors on the test performance of individuals and the procedures which have been suggested to reduce bias. (RJC)

This paper discusses applications of intelligence tests in schools, considering Binet's original warnings that his tests were primarily useful for identifying students needing intervention and inappropriate for classifying normal students. American applications of Binet's work for ranking are seen as stages of shifting from remedial to custodial…

This response to a paper by Linda Siegel (EC221505) discusses research on the relationship between social skills and Intelligence Quotient or academic performance. The research indicates that it is erroneous to assume that Intelligence Quotient or academic achievement account for the social problems of children with learning disabilities. (JDD)
