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.…

The differential impact of birth order and IQ on sibling roles were examined with particular interest focused on achievement outcomes. Subjects were a stratified sample of 37 pairs of near-in-age siblings, all within the normal range in personality and IQ, but differing significantly in scores on the Slosson IQ Test. Results indicate that when the…

A private corporation conducted a study for the United States Air Force in 1973, investigating the long term effects of drug use on general mental ability. The air force personnel selected for participation in the study were 3741 known drug users and 6772 controls. Subjects received requests to sign a form allowing their high schools to release…

Evaluated demographic and developmental differences in case studies of disturbed children (N=58) who were treated with developmental therapy. Results indicated children differed in age, intelligence, and mother's employment status. Although all children progressed in behavior, communication, socialization, and academics, no difference was found in…

The author reviews cross-sectional and longitudinal studies on the status of intelligence in the aging, and finds conflicting conclusions: (1) intelligence does decline as persons grow older; (2) only some aspects decline while others improve; and (3) intelligence does not decline. Certain factors are adduced to suggest that such…

Social, physical, emotional, and cognitive developmental rates for gifted children do not correspond to each other and--except for physical development--do not necessarily correspond to age peer norms. Giftedness itself causes asynchrony; that is, it causes children to be out of sync with other components. In the classroom, the teacher is…

A study designed to examine biological, sociological, and early maturational correlates of intelligence collected data prospectively, from birth to 15 years of age, on a sample of 987 black children. Multiple indicators of eight independent and three dependent variables were tested in a structural equation model. Altogether, clear sex differences…

Much of our thinking about contemporary social problems reflects tacit presuppositions regarding the operation of heredity and environment in human behavior. These beliefs have important implications for practical decisions. Advances in genetics, psychology, anthropology, and other disciplines have contributed much to a clarification of the…

Reviews the current theories concerning individual differences in cognitive functioning. While some argue that heredity places a genetic cap on intellectual development, others emphasize the dynamic interrelationship between cultural and environmental factors. Concludes that intelligence is more complex than the heredity advocates allow. (MJP)

The nutritional status of Kindergarten children has been studied in relation to performance in behavioral tests and the effects of several types of nutritional intervention in nutrition and behavior have been evaluated. In a study in 1969-70, children who received breakfast and lunch at school showed significant improvement in hemoglobin…

Seven contributors treat teacher diagnosis of educational difficulties. Robert Smith and John Neisworth review the fundamentals of informal educational assessment; Neisworth describes the educational irrelevance of intelligence; and Smith discusses perceptual motor skills. Also included are James Lister on personal-social-emotional skills, G.…
