Wolff has recently reinterpreted the data of Lee to indicate that Black migration from the south to Philadelphia had been selective in an IQ-relevant manner. However, Wolff's deduction from Lee's data is shown to depend entirely upon an assumption about cumulative IQ deficit in southern Black children. (Author/CTM)

Kamin has contended that arguments presented in Wolff are too weak to justify selective migration. Although Kamin's critique points up the need for closer scrutiny of the cumulative-deficit phenomenon, it fails to refute Wolff's conclusion that selective migration is partly responsible for the North-South Black IQ differential.

Reviewed are findings in the literature of racial differences in intelligence which are consistent in revealing "real differences in test performance between Negroes and whites." The interpretation that these racial differences are due to cultural bias in the tests is denied. A discussion of the genetic vs. environmental etiology of the…

The thesis that intelligence is based on heredity was dramatically revived in 1969 by an article in the "Harvard Educational Review" by Arthur Jensen, a psychologist at the University of California at Berkeley. The article, which received wide attention, was sharply criticized by those who hold that it is environment rather than genes which puts…

In an effort to isolate the emergence and causes of social class differences in intellectual performance, this longitudinal study was undertaken as a follow-up on a cross-sectional study that yielded no social class differences on the Cattell Infant Intelligence Scale for 12-, 18-, and 24-month-old black children. In the present study, 89 children…

Arthur R. Jensen's article presented no new data: it only reorganized a biased sample of already existent data. Nevertheless, it has been taken by opponents of school integration as definitive scientific evidence of the innate inequality of black and white students. Jensen and Van Den Haag advocate additional studies on individual learning ability…

This collection of essays about intelligence stems from the revived nature-nurture controversy about the origins of mental abilities, led notably by Arthur Jensen, whose article in 1969 created a furore in the U.S.A., and more lately by H. J. Eysenck in Britain. In planning this book, an attempt has been made to step back from the debate itself…

The results and interpretation of three years of research into inequality are presented in this book. Chapters cover these topics: (1) from equal opportunity to equal results; (2) inequality in the schools--access to schools and colleges, expenditure differences between schools and individuals, access to privileged school mates, and access to fast…

This illustrated booklet describes research procedures in the Infant Laboratory of the Educational Testing Service to investigate measurable factors in infant behavior which can predict intellectual potential. The research is currently focusing on attending, the manner in which infants respond to various stimuli presented to them during their…

A model-fitting analysis of the covariance structure of an intelligence quotient (IQ) data set is reported using a model that considers additive and nonadditive genetic parameters and shared and nonshared environment parameters that permit different estimates for different types of relatives. The use of LISREL for such purposes is reviewed. (SLD)

This longitudinal study attempted to assess how environmental factors affect the development of competence, as defined by White, by delineating in detail the everyday environmental transactions of a group of children from age 1 to 3. The key questions of this research were: (1) Are certain experiences encountered by the young child in his everyday…

The absence of a meaningful conception of Negro culture has forced the interpretation of almost all psychology's data on the Negro into two seemingly dichotomous categories: either that of biological incapacity, i.e., genetic inferiority, or social deviance and pathology, i.e., environmental deprivation. The cultural difference theory asserts that…

This book includes nine essays. In the Introduction: "The Lingering Infatuation with IQ," the editors argue that since the IQ test has again risen as an instrument of conservative policy, the test and the arguments built around it must be reexamined. Noam Chomsky criticizes the well-known "Atlantic" article, "IQ" (September, 1971), in "The Fallacy…

Urban and rural Aboriginal- and Anglo-Australian children were tested for reading and math achievement, for nonverbal psychometric test intelligence, and for three cognitive styles. Psychometric intelligence was clearly a more powerful predictor of the effects of culture and location on school achievement than was cognitive style. (Author/CMG)
