Discusses issues considered in the book "The Bell Curve: Intelligence and Class Structure in American Life" (Richard Herrnstein, Charles Murray), which stresses the importance of genetic differences between individuals and groups. The concept of a cognitive elite, cognitive classes and social behavior, ethnic differences in cognitive…

The ability of 248 older adults to improve their performance on fluid intelligence tests, with or without tutor-guided instruction in cognitive skills, was studied using multidimensional longitudinal structural equation models. Results suggest considerable plasticity in adult intellectual function and the capacity to improve performance. (SLD)

This paper argues that using intelligence as an aptitude benchmark in defining reading disability conceals unsupported assumptions about educational potential and makes it difficult to differentiate the cognitive characteristics of dyslexic children from those of other poor readers. The use of a more educationally relevant aptitude measure such as…

The use of adaptive behavior information for classification and placement of African-American and white students (n=707) with mental retardation was compared. Comparisons on general intellectual functioning and several indices of adaptive behavior yielded few differences, suggesting equal treatment was achieved despite substantial…

This study of 1,657 children (ages 7-16) found that although children with dyslexia had higher intelligence quotient scores than poor readers, the 2 groups did not differ in performance on reading, spelling, phonological processing, or most language and memory tasks. The performance of both reading-disabled groups was significantly below that of…

This overview of several programs, techniques, and approaches related to improving schools and student learning includes brief outlines of restructuring, effective schools, cooperative learning, whole language, technology, multiple intelligences, the Coalition of Essential Schools, the Accelerated Schools Project, the School Development Program,…

This study of 640 twins with reading disability and 436 controls (mean age 12) examined external validity of the distinction between specific reading retardation and reading backwardness, in 3 domains: genetic etiology, sex ratio and clinical correlates, and neuropsychological profiles. There was no evidence of differential genetic etiology of the…

Normative data for the Wechsler Memory Scale-Revised were derived empirically using a sample of 50 volunteers between 25 and 34 years of age, who matched U.S. Census data on demographic characteristics. Differences between these empirical norms and published norms that were estimated statistically appear clinically significant. (SLD)

Two key concepts in diagnosing learning disabilities ("severe discrepancy" and "process dysfunction") are reviewed, and their relationship to the habilitation of learning is discussed. Guidelines are given for calculating a severe discrepancy, and the evaluation of processing skills is discussed. Strength models of remediation…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

Critiques Walker's article in this issue. Argues that Walker's data do not meet technical standards regarding individual placement tests for normative comparisons, interjudge reliability, or predictive validity, and therefore do not justify the use of the Gesell test to place children in developmental kindergarten or transitional first grade.

Describes six types of instructional technology used in the nuclear industry: Study Pacs, computerized test banks, computer-based training, interactive videodisc, artificial intelligence, and full-scope simulation. Each description presents the need, training device, outcomes, and limitations or constraints on use. (SK)

Discusses the application of artificial intelligence to online information retrieval systems and describes several systems: (1) CANSEARCH, from MEDLINE; (2) Intelligent Interface for Information Retrieval (I3R); (3) Gausch's Query Reformulation; (4) Environmental Pollution Expert (EP-X); (5) PLEXUS (gardening); and (6) SCISOR (corporate…

Using a "review of reviews" methodology, this literature synthesis on stimulant use with children with attention deficit disorder compared three reviews from each of three review types (traditional, meta-analytic, general audience). A consensus was found to exist about the expected benefits and the acknowledged limitations of stimulant medication.…

Examined the relationship between depression rates, IQ, knowledge of the finality of death, exposure to suicidal behavior and knowledge of suicide methods. Found that the effect of these factors differed between suicidal and nonsuicidal psychiatrically hospitalized children and developmentally delayed adolescents. Also found that the factors had…
