The theoretical background, organization, performance subtests (object assembly, geometric design, block design, mazes, picture completion, and animal pegs), verbal subtests (information, comprehension, arithmetic, vocabulary, similarities, and sentences), reliability, validity (factor analysis), interpretation, advantages, and limitations of the…

The Cognitive Levels Test, for use with ages 5-21, is designed as a quick cognitive assessment instrument with 4 subdomains: verbal reasoning, abstract reasoning, quantitative reasoning, and memory. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)

The Stanford Binet Intelligence Scale measures four areas of cognitive abilities (verbal reasoning, abstract/visual reasoning, quantitative reasoning, and short-term memory), providing a continuous scale for appraising cognitive development from age two to adult. This paper describes the test's administration, standardization, reliability, and…

Discussion of time-related measures in computerized ability tests focuses on a study of college students that used two intelligence test item types to develop a multitrait, multimethod assessment of response time measures. Convergent and discriminant validation are discussed, correlations between response time and accuracy are examined, and…

Discusses visual literacy and its impact on school performance. Topics include rising scores on intelligence tests; the importance of visual literacy skills for university students; and implications for school practices related to technology, including teaching methods, teacher training, and equity issues. (LRW)

Examines national data sets of cognitive scores for intellectual dysgenesis by considering race, socioeconomic status, and ability-related changes in test scores over time. The analysis did not support the dysgenic hypothesis; however, it indicates a convergence of the various segments of U.S. society. (MMU)

Five-year follow-up study examined the predictive validity of the Kaufman Assessment Battery for Children (K-ABC) for 39 children identified during preschool as exhibiting language impairment (n=10), behavior control deficits (n=13), or normal language and behavioral development (n=16). Results generally supported the predictive validity of the…

The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…

Current psychometric and testing practices are inadequate for assessing the intelligence of American Indian students, due to complicating factors of culture and language. These deficient methods are then used to make educational decisions, resulting in improper special education placements. The benefits of alternative methods of testing, including…

D.V. Cicchetti, A.S. Kaufman, and S.S. Sparrow (this issue) use six criteria to evaluate the published findings from seven different studies of PCB exposure and neuropsychological function. They point out a number of weaknesses or flaws in each study and conclude that these weaknesses make the overall conclusion that PCB exposure negatively…

Background: Developmental dyslexia is typically defined by deficits in phonological skills, but it is also associated with anomalous performance on measures of balance. Although balance assessments are included in several screening batteries for dyslexia, the association between impairments in literacy and deficits in postural stability could be…

The predictive validity and utility of assessment procedures can be increased by adding predictors to the prediction supplied by general ability tests. Of Jensen's early work comes the suggestion of focusing on the cognitive ability short-term memory (STM), especially for low-"g" Black children. Meta-analysis convincingly shows high…

The main purpose of this study was to evaluate the effects of a package of activities, known as "Portfolio", on cognitive functioning, self-regulation, and academic achievement. The study was carried out with a group of 40 students from Compulsory Secondary Education (mean age 13 years old) during 120 hours distributed over two school years. A…

Researchers have typically found a mean difference of about 15 points between Blacks and Whites on traditional measures of intelligence. Some have argued that the difference between Blacks and Whites would be smaller on measures of cognitive processing. This study examined Black (n = 298) and White (n = 1,691) children on Planning, Attention,…

The primary purpose of this study was to test two hypotheses proposed by Bracken and McCallum (1998), authors of the Universal Nonverbal Intelligence Test (UNIT), as to how children diagnosed with ADHD would perform on the UNIT. Twenty-nine students between the ages of 5 and 17 years were administered the extended battery of the UNIT twice, with…
