Etiology of high and low cognitive ability in adulthood was explored through multiple regression analysis of data from 302 pairs of Swedish twins (median age=65.6 years). Both high and low cognitive ability groups demonstrate significant group heritability, with shared rearing environment of relatively low importance. (SLD)

This study of 68 scientifically gifted Korean high school students indicated that males and females are more similar than different on mental health profiles. Both sexes were relatively free of maladjustment, with males scoring higher on self-criticism than females. Self-concept was correlated with intelligence but not with achievement.…

Dynamic assessment is presented as a method of measuring intellectual ability which addresses criticisms of traditional intelligence tests. Dynamic assessment can be used to identify children's learning abilities, determine how and/or what to teach, assess giftedness in minority and poor children, control for individual differences, and explore…

Development of an alternate form of Raven's Standard Progressive Matrices Test is described. Reliability analysis with 449 children of differing racial/ethnic backgrounds showed good reliability and comparable predictive validity. The alternate form is a promising research tool. (SLD)

According to Herrnstein and Murray's "The Bell Curve" (1994), public education cannot alter the economic, social, or political stratification of American society. Intelligence is supposedly being combined and concentrated, and there is no inexpensive, reliable method to raise IQ. Actually, the book justifies the economic status quo and a…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

Procedures recommended in the Wechsler Intelligence Scale for Children (Third Edition) (WISC-III) manual for factorial estimation may be replaced by new methods using the computer and a spreadsheet program. Constants and formulas needed to draft a spreadsheet program for estimating the factors using WISC-III scaled scores are presented. (SLD)

This study of third-grade and fourth-grade children with (n=59) and without (n=57) learning disabilities found that LD students perceived themselves as less competent in the areas of intelligence, academic skills, behavior, and social acceptance. Contrary to expectations, subjects' self-perceptions were not affected by the choice of LD or general…

Includes abstracts of 18 special interest group (SIG) sessions. Highlights include natural language processing, information science and terminology science, classification, knowledge-intensive information systems, information value and ownership issues, economics and theories of information science, information retrieval interfaces, fuzzy thinking…

Calls for careful but unemotional criticism of "The Bell Curve." Notes that: three chapters that deal with the IQ-race relationship have received most critical attention; genetically based racial categories do not exist; disadvantaged minority-group students have achieved success in Catholic schools with high expectations of students;…

This article reports the results of using a three-layer back propagation artificial neural network to predict item difficulty in a reading comprehension test. Three classes of variables were examined: text structure, propositional analysis, and cognitive demand. Results demonstrate that the networks can consistently predict item difficulty. (JL)

Presents an interview with a professor at the Harvard Graduate School of Education. Highlights include school improvement, cognitive development, multiple intelligences theory, school reform issues, national assessment and standards, the value of education in the United States and other countries, curriculum development, schools of the future,…

Explores some speculative hypotheses on states of knowing and learning, and how these states and processes might be applied to artificial intelligence and expert systems development. (JKP)

Views school readiness as an ideological issue affecting American society and dominated by middle-class white values, which results in different treatment for middle-class students and "deficient students." Advocates moving away from a two-tiered system of education and toward a more democratic form of schooling that recognizes multiple…

Considers the possibility of designing CAI (computer-assisted instruction) systems that are managed by semantic networks. Topics discussed include general descriptions of the suggested approach, lesson-presentation modes, and the architecture of a CAI system managed by a semantic network. (10 references) (MES)
