Analyses of 109 drug-abusing adolescents indicated that inhalant abusers performed significantly more poorly than polydrug abusers on 20 of 67 neuropsychological measures. Deficits were observed on both global (WAIS and WRAT) and specific measures (perception of speech sounds, visual suppression, sensory perception, and trails). (Author/SJL)

The scores of elementary school students on the Quick Test were compared with scores on the Full Scale Wechsler Intelligence Scale for Children-Revised. The relationship between the two tests varied significantly with age and intelligence levels. (Author/CP)

This study provides guidelines for practitioners to determine the minimum differences, in scaled score points, needed for statistical significance when applying the Bannatyne recategorization of Wechsler Intelligence Scale for Children--Revised subtests on a individual basis. (Author)

The Genetics Society of America has released a statement saying that the possibility of a "genetic difference in intelligence between races" is still an open question and warning against "the misuse of genetics for political purposes". (Editor)

Responds to "Birth Order and Intelligence: Further Tests of the Confluence Model" by Robert D. Retherford and William H. Sewell. Reviews their arguments and suggests that their analyses of the Wisconsin Longitudinal Study data support rather than contradict the model. (CJS)

Uses neuropsychological and developmental models of number, counting, and arithmetical skills as well as supporting working memory and speed of articulation systems as the theoretical framework for comparing groups of low- and average-IQ children. Indicates that low-IQ children's conceptual understanding of counting did not differ from that of…

Describes a system of categories to subdivide the gifted and talented population into the following more homogeneous subgroups: mild, moderate, high, exceptional, and extreme. Based on the metric system, each of the five levels, including the minimum threshold, selects the top 10% of the previous level. (Author/CR)

This article considered some of the assumptions underlying studies of race and I. Q., the degree to which these studies can serve as secure guides to educational strategies, and the wider implications of such research for the value systems that operate within academic institutions. (Editor/RK)

Some of the key problems of educational equality -- equality of opportunities and inequality of performance; individual differences vs. group differences, coping with group inequality -- are made explicit. (Author/KM)

A critical review of Jensen's book which contains a reprint of the original controversial 1969 "Harvard Educational Review" article, 5 related articles by Jensen, and a bibliography of related articles. (EH)

Report of a set of tentative estimates of the economic impact of infant malnutrition in Santiago, Chile. The economic costs and benefits of alleviating malnutrition are discussed in terms of their policy implications. (EH)

The essential components of self-paced systems are frequently prohibitive in cost for implementation for all students. Selection of students who can profit most from individualized programs can be made by choosing students in upper and lower extremes in mental ability who possess certain elements in their cognitive styles. (Author)

The author argues that no "hard" data exists on genetically based differences in intelligence among human groups. IQ measures the heritability of IQ, and statistical inaccuracies in reported studies are discussed and questioned. The current interest in biological determinism of intelligence is trivial; individuals can not be judged by group means.…
