Factorial invariance of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) when administered to deaf children who use sign language was studied with 110 children and the WISC-III standardization sample of 2,200 children. Path coefficients, error variances, and factor covariances were not invariant, indicating that test…

Summarizes some prevailing policies and practices important to the assessment of mental retardation in Australia, France, the United States, and Zimbabwe. Discusses international standards for diagnosis and classification of mental disorders and cross-national similarities and differences. Also discusses implications for test development. (SLD)

The Kaufman Brief Intelligence Test (K-BIT) (A. S. Kaufman and N. L. Kaufman, 1990) was compared with short forms of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) using results from 64 referrals to a neuropsychology service. Advantages of each test are noted and their use discussed. (SLD)

Recent decades have seen major changes in measurements of cognitive ability and interpretation of results. Theory describing the factorial structure of cognitive ability has blossomed. Advances in psychometric and statistical tools available to test developers have facilitated application of better theory to new assessment instruments.(SM)

Studied the relationships between two real time dynamic decision making tasks (microworlds) and one intelligence test with 100 Swedish adults. Raven's Progressive Matrices scores were a predictor of success in the two microworlds. Discusses methodological problems with microworlds. (SLD)

Conducted follow-up study of 43 subjects in mentally retarded residential population. Findings corroborated earlier findings that Wechsler Intelligence Scale for Children-Revised and Wechsler Adult Intelligence Scale-Revised (WAIS-R) cannot be regarded as equivalent testing instruments. WAIS-R yielded consistently higher scores for intellectually…

Content analysis of the Columbia Mental Maturity Scale and the Test of Nonverbal Intelligence (TONI) revealed differences in the nature of perceptual and conceptual items. Both language-impaired and normal-language children performed significantly better on perceptual-type than conceptual-type items. The predominance of perceptual items was…

J. Dirks (1982) reported that the Block-Design subtest score from the Wechsler Intelligence Scale for Children--Revised is amenable to practice effects transferred from a game. Results from the assessment of two other spatial games, using 37 children in daycare (23 experimentals and 14 controls) indicate no transfer effects. (TJH)

The study examined Performance and Verbal IQ scores for 27 depressed and 15 nondepressed children (mean age 10 years) with learning difficulties. Previous findings (Brumbach, 1985) of a significant association between depression and Performance IQ deficits were not supported by the current study. (Author/DB)

Administered Wechsler Preschool and Primary Scale of Intelligence (WPPSI), Peabody Picture Vocabulary Test-Revised (PPVT-R), and Expressive One-Word Picture Vocabulary Test (EOWPVT) to 70 preschoolers identified at-risk. PPVT-R and EOWPVT were found to be significantly correlated with Verbal and Full Scale Intelligence Quotient (IQ) scores of…

The study investigated the concurrent validity of the Peabody Picture Vocabulary Test-Revised and Expressive One-Word Picture Vocabulary Test with the Wechsler Preschool and Primary Scale of Intelligence for 15 language delayed and 36 non-language delayed children (ages 45 to 76 months). (DB)

A chemistry professor emeritus explains the misguided association between gout and genius. Gout, a genetic disease arising from overproduction of uric acid, was prevalent in many historical, upper-class male figures. Gout is equally prevalent in poor rural blacks. Since both populations probably suffered from ingesting lead-poisoned alcoholic…

Protocols (n=149) of the Wechsler Adult Intelligence Scale-Revised that were completed by 22 graduate students were analyzed to determine the effectiveness of practice administrations in developing examiner competence. Even completing 10 administrations did not reduce errors students made, suggesting that careful training is required. (SLD)

Composite reliability and standard errors of measurement were computed for prorated Verbal, Performance, and Full-Scale intelligence quotient (IQ) scores from a seven-subtest short form of the Wechsler Adult Intelligence Scale-Revised. Results with 1,880 adults (standardization sample) indicate that this form is as reliable as the complete test.…

The clinical utility of the cluster solution of core profiles of the Wechsler Adult Intelligence Scale-Revised by McDermott and others (1989) was studied with 161 brain-damaged patients. Core profile methodology was not sensitive to brain damage and lacked neurodiagnostic utility. (SLD)
