This meta-analysis reviews 79 studies (N = 46,605) that examined the existence of gender difference on intelligence in school-aged children. To do so, we limited the literature search to works that assessed the construct of intelligence through the Wechsler Intelligence Scales for Children (WISC) batteries, evaluating eventual gender differences…

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…

Evaluates three approaches to dynamic assessment of intelligence in terms of their ability to address both classification and remediation functions of assessment in schools. Argues that relative to traditional intelligence tests, dynamic approaches have failed to provide evidence of satisfactory technical characteristics, such as reliability and…

Researchers have examined inductive reasoning to identify different cognitive processes when participants deal with inductive problems. This article presents a prescriptive theory of inductive reasoning that identifies cognitive processing using a procedural strategy for making comparisons. It is hypothesized that training in the use of the…

Argues that IQ tests work only for some people some of the time. Offers a theory that emphasizes the roles in intelligence of information-processing, the environmental context, and coping with novelty and automatization of task performance, as a possibility for improving levels of prediction.

Nine questions that link performance on the Kaufman Assessment Battery for Children to classroom teaching and pupil learning were posed. Results revealed the absence of empirical validation for linking K-ABC scores and altered teaching methods to known and desirable outcomes. (Author/CL)

This paper presents a description of four schools of thought on the nature of intelligence, some findings that have emerged from them, and an indication of how these findings reveal a common core of generalizations across the various schools. (Author/SJL)

This paper examines reports of empirical research on Feuerstein's "Instrumental Enrichment" (FIE) as a method of teaching thinking skills and asks what can be concluded from these reports with regard to: (1) the nature and statistical reliability observed FIE effects and (2) the "amount" of FIE for effects to appear.…

This article reviews Raymond B. Cattell's important contributions to intelligence testing and the theory of intelligence. His theory of fluid and crystallized intelligences and other high-order factors of cognitive ability has offered the most well-founded and reasonable approach to an acceptable theory. (Author/BS)

Performance on items in intelligence and achievement tests can be represented in terms of child development and information processes. Research is reviewed on item performance that supports developmental and information processing effects, particularly in children. Some suggestions regarding item development are made. (Author/TJH)

Howard Gardner's Multiple Intelligence construct is considered from the perspective of its viability in gifted education, especially in comparison with the more traditional Intelligence Quotient-based construct of intelligence. Empirical and theoretical support and contradictory findings are discussed from the literature in cognitive science and…

Major research findings relevant to use of the Wechsler Digit Span subtest in psychoeducational assessment are summarized. The cognitive processes and behavioral characteristics which determine performance on Digit Span are related to complex abilities. Recommendations and implications for research and assessment practice are presented.…

This article briefly traces the development of intelligence testing from its beginnings in 1905 with Alfred Binet; cites the intelligence theories of Spearman, Thurstone, and Guilford; and examines current objections to intelligence tests in terms of what they test and how they are interpreted. (SJL)

This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)
