The construct validity of the Sequential Processing, Simultaneous Processing and Achievement scales of the Kaufman Assessment Battery for Children was supported by factor-analytic investigations of a representative national stratified sample of 2,000 children. Correlations provided insight into the relationship of sequential/simultaneous…

Twenty-four measures of crystallized intelligence and fluid intelligence were obtained for samples of graduates and failures of an innovative instructional setting where computer-managed mastery learning was implemented to teach elementary electricity and electronics. Results suggest that some unconventional educational environments are not…

Seeing intelligence as neither strongly hereditary nor necessarily stable over time, and accepting the notion that it is a significant determinant of future occupational status, liberal psychologists and educators rely on the intervention of social institutions, primarily the school. The liberal view toward testing and intelligence is discussed.…

The preceding article by Robert Sternberg implicitly accepts the idea that there is a single human potential called "intelligence" that is scientifically measurable. Human beings do not possess any such generalized intelligence, however. Instead, each person possesses a mix of several basic intellectual competencies or…

Thorndike's Stanford-Binet data suggest that from 1932 to 1971-72 preschool children enjoyed greater IQ gains than older children, possibly due to the rise of television. Additional analysis indicated that gains were either due to sampling error or totally antedated 1947. Gains of 12 IQ points were found for Americans. (Author/EGS)

The relationship between psychometric intelligence and rapid acoustic information processing was explored in two experiments using college students. Group differences occurred in threshold interstimulus intervals required for recognition and in speed. Results were interpreted as indicating better information processing efficiency (higher…

The hierarchical and radex models of ability organization are shown to be parallel. Both suggest a complexity continuum for cognitive performance tasks which, in the radex model, corresponds to the general-to-specific dimension in factor analyses. The bases for this continuum indicate its importance for theories of intelligence. (Author/RD)

Where estimation of abilities in the lower half of the ability distribution for the Raven Progressive Matrices is important, or an increase in accuracy of ability estimation is needed, the multiple category latent trait estimation provides a rational procedure for realizing gains in accuracy from the use of information in wrong responses.…

The major findings of this study support the view that the social environment plays a dominant role in determining the average IQ level of black children and that both social and genetic variables contribute to individual variation among them. (Author/AM)

Timed and untimed scoring methods were employed with five WAIS subtests administered to 40 young and 40 old subjects matched for verbal intelligence. Elimination of bonuses for rapid performance differentially improved the scores of older subjects but did not raise those scores to levels achieved by the young. (Author)

The State of Washington special education regulations address the eligibility determination for specific learning disabilities and require the development of regression tables for calculating a severe discrepancy between intellectual ability and academic achievement. The Office of Superintendent of Public Instruction (OSPI) Special Education,…

Since Howard Gardner proposed the theory of multiple intelligences as an alternative to the unitary concept of general intelligence, educators have been searching for an acceptable method of assessment. To help with this search, three studies that describe the development and validation of a self- (and parent-) report measure of children's…

The publication of "The Bell Curve" by R. Herrnstein and C. Murray enraged many with its contention that black children are genetically less able to learn because of their race and its suggestions that some groups may be less worthy of the expenditure of attention and resources because of a reduced capacity for education. This collection…

The Multiple Intelligences Developmental Assessment Scales (MIDAS) instrument was developed to measure eight constructs of intelligence. The 119-item MIDAS provides scores for 26 subscales in addition to the 8 major scales. Using the 26 subscales, a factor structure was developed on half of a U.S. sample of college students (n=834), while the…

Argues that from a black perspective, the real concern is not merely that of defining intelligence, about which there is lacking a consensus among psychologists, but one which challenges the basic scientific considerations of validity, reliability, and standardization of intelligence tests.
