Introduces the inspection-time (IT) measure in psychology, and argues that its much-replicated correlation with intelligence quotient (IQ) and its potential for theoretical tractability has more potential for the understanding of individual differences in cognitive ability than other indices of human information processing. It summarizes studies…

The problem of dimensionality with respect to Raven's Advanced Progressive Matrices (APM) specifically and, more generally, "g" or fluid intelligence, has been a long-standing issue. The present article reports two studies examining the dimensionality of both the original Set II of the APM (n = 506) and a short form (n = 644), using principal…

This investigation explored the accuracy of a short form of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III} in predicting Full Scale IQ when administered as a separate test. The Dumont-Faro short form (i.e., Picture Completion, Information, Coding, Block Design, and Vocabulary; Dumont & Faro, 1993) was administered to 60…

Non-verbal tests are paper-and-pencil tests that are designed to measure cognitive processes that do not involve verbal language. Such tests use shapes, patterns, diagrams, and sequences to measure general intellectual skills of a non-verbal nature. The use of such tests in schools is described. Performance tests using concrete apparatus are…

A Group of children were given the Otis Lennon Mental Abilities Tests in grades 3, 5, and 7, to measure the degree of score consistency over time. The test predicted future academic success only moderately well in grade 5 and slightly, if at all, in grade 3. (Author/SJL)

The efficacy of Raven's Matrices in the gifted identification process is reviewed, focusing on their reliability, validity, and fairness and comparing them with other intelligence tests. It is concluded that, despite problems with narrowness of scope and standardization practices, these tests provide a useful screening device for intellectually…

The GEON-Project (1973-80) was a teacher-oriented program to improve kindergarten education in certain Dutch schools. Teachers were trained in diagnostic and differentiated teaching methods to improve students' emotional and cognitive development. The summative program evaluation found improvement in intelligence test results, but student school…

Discrepancies between the K-ABC and its theoretical base of simultaneous and sequential mental processing; technical and design problems related to disproportionate subtest contributions of the Simultaneous Scale to the Mental Processing Composite; the method of subtest-specific variance computation and use in interpretation; and utility with…

Previous findings have indicated that the reasoning abilities of gifted students are associated with gender differences. However, the factors affecting the emergence of gender differences, including age, remain to be studied. The main purpose of this study is to investigate whether the spatial, verbal and quantitative reasoning abilities of gifted…

The System of Multicultural Pluralistic Assessment (SOMPA) is described as an example of the structural and cultural pluralistic model of assessment. Mercer's concept of estimated learning potential is described and the medical, social, and pluralistic models are mentioned. Standardization, test administration, validation, and the manuals are…

Five papers concerning standardized testing are presented. Topics addressed include measures for distinct aspects of human intelligence (multiple intelligences), the use of portfolio assessments with regard to instructional planning, practical reasoning, cognitive and conative constructs, and cognition and assessment practices. (TJH)

This critical evaluation of the Slosson Intelligence Test (SIT) determined that the test items are 30 years old, scores are derived from a nonrepresentative norm group, and scores are not interchangeable with other intelligence measures. The paper concludes that the SIT is unsuited for educational decision-making purposes, including screening,…

The six articles of this theme issue relate the history of empirical research in education to its sociohistorical background, examining the proposition that the rise of empirical research in education was linked to complex factors such as the rise of positivism in the 19th century or the institutional growth of an educational market. (SLD)

Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

There is a resurgence of scientific and public interest and controversy centering on four interrelated themes: (1) intelligence testing; (2) racial, ethnic, and socioeconomic differences in measured IQ; (3) genetic and environmental influences on abilities; and (4) the role of scientific research in social policy. Given the polarization of views,…
