Persons representing the extremes of intelligence cannot be included in the same study unless they are approximately equated on mental age, in which case the relative performances of the extreme groups can provide useful information about the nature of intelligence. (Author/RD)

This article reviews sex studies of children of cousin marriages and three studies of children of incestuous matings. It is argued that these studies, taken as a whole, provide no substantial evidence for an inbreeding depression effect within the polygenic system commonly asserted to determine IQ. (Author/DB)

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

Multiple regression is used to discover interconnections between IQ and vocabulary test scores as one variable, and socioeconomic factors as the other. Results show total variance as explained by predictors is never more than eight per cent, indicating differences in IQ scores are not attributable to environmental factors. (RW)

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…

The Flynn effect, documented by a New Zealand political scientist, refers to the fact that average IQ scores have been increasing over time, reflecting the effects of environmental factors. Implications for the measurement of the intelligence of African American children and their educations are discussed. (SLD)

As a response to recent public debate about the nature of intelligence, this article reviews the "state of the art" in the study of intelligence, exploring significant conceptualizations of intelligence, the use and interpretation of intelligence tests, racial or ethnic differences in intelligence, and major issues yet to be resolved.…

Presents social scientists' claim that IQ scores can determine a person's social, educational, and occupational future at an early age. Echoes the Platonic idea that each individual should be put to the use for which nature intended, and that IQ, which is thought to be hereditary, can effectively predict this use.

We review past and current psychometric theories about intelligence and critically evaluate the usefulness of modern IQ tests in guiding decisions within an educational context. To accomplish this we consider whether knowledge about intelligence extends beyond mere description to provide a scientific framework for further advancing our…

A total of 378 Hong Kong adolescents estimated their own and their parents' IQ score on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body-kinesthetic, interpersonal, intrapersonal, existential, spiritual and naturalistic. They answered three simple questions concerning intelligence and…

The impetus for our study was the contention of both Lynn [Lynn, R. (1991) "Race differences in intelligence: A global perspective." "Mankind Quarterly," 31, 255-296] and Rushton [Rushton, J. P. (1995). "Race, evolution and behavior: A life history perspective." New Brunswick, NJ: "Transaction"; Rushton, J.…

Author explained what the quotient in IQ stands for, whether the IQ changes, how to relate IQ to other factors, and its future in measuring human intelligence and personality development. (RK)

THE RELEVANCE OF INTELLIGENCE TESTS FOR EDUCATIONAL USES IS CHALLENGED ON TWO GROUNDS--(1) TESTS WHICH MERELY PREDICT THE LIKELIHOOD OF FUTURE SUCCESS DO NOT PROVIDE USEFUL INFORMATION FOR THOSE WHO WISH TO PRESCRIBE TREATMENTS TO ENHANCE PERFORMANCE, AND (2) INTELLIGENCE IS NOT DEFINED AND HENCE THE INTERPRETATION OF SCORES IS MISLEADING. IT IS…

Evidence of a relationship between the electrical responses of the human brain and psychometric measure of intelligence is presented. These involuntary cortical responses, known as average evoked potentials are considered to be the electrical signs of information processing by the brain. The time delays of these responses from presentation of a…

The purposes of this study were to investigate adolescent intellectual decline, and to attempt to determine some of the sexual differences possibly inherent in the phenomenon. It was hypothesized that (1) girls would decline in greater numbers and to a greater degree than boys; and (2) areas and amounts of sex differences of the decliners would…
