With the advent of quantum mechanics, physics has merged with psychology, and cognitive science has been revolutionized. Quantum logic supports the notion of influencing the environment by increasing the child's capacity for cognitive processing. This special educational approach is theoretically more effective than social and political…

Discusses issues raised in "The Bell Curve: Intelligence and Class Structure in American Life" (Richard Herrnstein, Charles Murray), a controversial book that looks at the role of intelligence in shaping social structure. The authors' methodology, approach, and interpretations of statistical data are criticized. It is suggested that a…

Examined whether differentiating processes existed for 7 composite indices of positive and negative adolescent adjustment in 720 sibling pairs. Found that siblings born 1 year apart at Time 1 were more similar to each other than were siblings born 2 years apart, suggesting that shared environmental influences counteract sibling differentiation…

Theories explaining differences in IQ performances between races in terms of (a) genetics and (b) the role of the environment are both criticized. It is argued that the Cultural Distance Approach, which stresses the role of a subculture's distance from the major culture on which IQ questions are based, has the greatest explanatory power. (RDN)

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)

Suggests that Dunn's genetic explanation for low Hispanic academic achievement is flawed, racist, and scientifically unfounded. Reviews historical efforts to suppress foreign language use and instruction in the United States. Calls for a reexamination of the implications of IQ test results in light of socioeconomic and cultural differences.…

Reviews criticism of Dunn's monograph on Hispanic-Anglo differences in IQ scores. Discusses the heritability and malleability of IQ, the reciprocal relationship between achievement and intelligence, negative effects of schooling for some caste-like minorities, and superior cognitive skills among balanced bilingual students. Contains 19 references.…

The egalitarian dogma, the belief that blacks and whites are genetically equal in cognitive ability, has been perpetuated through intimidation and pious thinking. Data on racial differences and the corruption of scholarship that causes them to be ignored are discussed. (SLD)

Data from the Colorado Adoption Project for 493 first-grade adopted and nonadopted children are used to separate parental intelligence quotient (IQ) from the effects of school environment. Several of the variables show direct environmental associations with reading and mathematics achievement independent of effects of parental IQ. (SLD)

Examines Black social scientists' intellectual efforts, starting in the 1920s, to challenge research conclusions about the innate mental inferiority of Blacks, disclaim the validity of intelligence tests used, and demonstrate the influence of environment on test performance. Finds irony in Black intellectuals' use of the mental tests they…

Two studies investigated how social class and race are associated with mathematical thinking. The first study compared poor Black preschoolers with a group of both Black and White middle-class children; the second study compared Black and White children of lower- and middle-class status. Children were drawn from both preschool and kindergarten…

Adoptive parents and their adoptive and natural children took IQ tests. Speed of solution correlated with verbal IQ and .51 with performance IQ among the parents. Mothers' speed correlated negligibly with scores of adoptive and natural children. Fathers' speed correlated more with their natural than adopted children's performance scores.…

Sex, body size, several sociocultural variables, and status rank were measured in mixed-sex small groups. The intervening sociocultural variables explained some but not all of the interrelationships. Results underscore the empirical vulnerability of social-psychological explanations of sex-role behavior and signal the need for further research.…

Swedish longitudinal studies of twins support Scarr-Salapatek's explanation of nature-nurture influences on intelligence. This model predicts more genetic variance in test results for advantaged than disadvantaged groups. Jensen's work, however, suggests equal amounts of variance among different social classes. (Author/CP)

This article summarizes the thesis of "The Bell Curve: Intelligence and Class Structure in American Life," noting its rejection of educational intervention to solve social problems correlated to low IQ. It critiques the book for its failure to consider important research findings, and addresses the race issue, urging that the book's…
