We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

Background: Data from sex offender treatment programmes (SOTP) on the re-offending of convicted sex offenders from the prison service in England and Wales was recently reviewed and found to be associated with no change in sexual reoffending. While this result is at variance with a number of other reviews it does give rise to concern as most…

The article reviews the history of intellectual assessment of children and adolescents in Greece, as well as procedures, current practices, and future directions. Although the history of special education is long in Greece, there has been very sporadic and incoherent legislation and decision making on the subject. Currently, intelligence tests are…

Children born preterm are at risk for developmental deficits across multiple functional domains. As the rate of survival for preterm infants increases due to medical advancements, a greater understanding is needed for how to meet the needs of this growing population in schools. Because approximately 50-70% of children born preterm require…

Assessment is a crucial component of gifted education. Not only does it facilitate the recognition of the potential and specific needs of gifted students, it also monitors the progress and growth of gifted students, and allows for the evaluation of gifted education programs. In the present review, we synthesize the literature on assessment in…

On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the…

Much has been written about gifted students with learning disabilities, but there have been few large-scale empirical investigations, and the concept has proven controversial. The authors reviewed the available empirical literature on these students, focusing on (a) the criteria by which the students were identified and (b) the students'…

A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of 0.77 and 0.78 were found…

The Wechsler Adult Intelligence Scale-3rd Edition (WAIS-III) was released in 1997. Short forms developed for previous versions have not yet been investigated for the WAIS-III in special populations. A 4-subtest short form by A. B. Silverstein emerged as the most promising short form in an elderly sample. (Contains 49 references, 4 tables, and 2…

Profile analysis refers to interpreting or analyzing the pattern of tests, subtests, or scores. The analysis may be across groups or across scores for one individual. This approach to analyzing data is being used by clinicians to help in the translation of the results of popular assessment instruments. This paper examines several examples of the…

Describes research involving adolescent marijuana abusers. Using Wechsler Memory Scale-Revised and Wechsler Adult Intelligence Scale-Revised found characteristics consistent with pattern produced by cerebral dysfunction including reduced memory indices in relation to intellectual function and attentional ability. Intelligence was found to be in…

Tables are presented for the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) IQ and index scores by education level for both the U.S. and Canadian normative samples. This allows clinicians to provide more accurate identification of relative strengths or weaknesses, compared to expectations from an individual's background, rather than…

Explores alternative empirical foundations of verbal and performance dichotomous constructs of Wechsler Intelligence Scales. Argues that Macmann and Barnett's position on the value of these constructs are based upon narrow interpretations of investigative results. Supports contention with IQ data from investigations of diverse populations. (CRR)

The author reviews research to show that the Wechsler Scales (the Wechsler Intelligence Scale for Children, the Wechsler Intelligence Scale for Children-Revised, and the Wechsler Adult Intelligence Scale) can be grossly unrepresentative of the general population in identifying mental retardation. (CL)

Reacts to previous arguments regarding verbal and performance constructs of Wechsler Scales. Contends that general factor model is more plausible representation of data for these scales. Suggests issue is moot when considered in regards to practical applications. Supports analysis of needed skills and instructional environments in educational…
