This author reviews published data and presents new data relevant to the Spearman hypothesis concerning racial differences on cognitive tests. He concludes that across-the-board difference between SES groups occurs primarily on the general factor, and that there are major determinants of race differences independent of the general factor.…

The author responds to criticisms made by Jensen pertaining to tests of the Spearman hypothesis. The near-zero correlation between Blacks and low socio-economic status Whites is neither an artifact of methodology nor a sampling fluke. Low and high SES White differences are highly correlated with general factor loadings. (LMO)

Argues that Herrnstein and Murray's cognitive stratification is not intrinsically ominous, since context determines its meaning; their "intelligence" data actually measures educational achievement; environmental effects are underestimated; and analyses and social policy recommendations are bound to the U.S. context. Concludes that…

The history and use of intelligence testing are reviewed, with emphasis on the validity of intelligence tests for black populations. Different definitions of intelligence are summarized, followed by an historical review of intelligence testing. The work of Alfred Binet is discussed, as well as the validity and reliability of his scales. A…

This paper focuses on the use of the variable race in educational research. Researchers are clearly considered to have the right to choose their variables. But, the use of race in a nonscholarly fashion is held to be professionally inadequate and often detrimental to black Americans. For years, researchers using race to make comparison s between…

Psychologists and a few sociologists have provided the academic respectability for the political rationale that the American body politic's civil rights indigestion needs a resurrected, separate but equal diet. Today, it is intellectually respectable to question the genetic equality of whites and blacks, to assert the cognitive incapacities of…

The basic tenet of this paper is that the difference between black and white children on IQ measures is not due to genetics but describes the cultural distance between the two groups. The cultural distance approach is described as an amalgam of the environmental and social psychology points of view. It holds that any subculture operating according…

This book is considered to provide a sober, balanced, and scholarly examination of the evidence that bears on the role of genetic and environmental factors in the determination of group differences in ability in the United States. The first chapter provides something of the background and recent history of the concern with racial-ethnic…

The identification of talent, and the understanding of its development and origins in terms of biographical data were investigated. The three central objectives were: to construct separate empirical procedures for Anglos and Blacks to predict certain academic performance criteria; to construct an empirical scoring procedure that could predict…

In previous studies of ethnic group bias in intelligence test items, the question of bias has been confounded with ability differences between the ethnic group samples compared. The present study is based on a conditional probability model in which an unbiased item is defined as one where the probability of a correct response to an item is the…

In 1969-70, the research department of the Children's Television Workshop (CTW) established research sites in day care centers to provide feedback to the CTW staff and to conduct a controlled study of the educational benefits derived from viewing the program "Sesame Street." A randomized sample of 200 preschool students was given an…

In these hearings, the following witnesses presented testimony: Dr. Henry E. Garrett, Chairman, Psychology Department (Emeritus), Columbia University; Dr. Arthur R. Jensen, Professor of Educational Psychology, University of California at Berkeley; Dr. Frank C. J. McGurk, Professor of Psychology, University of Montevallo; Dr. R. Travis Osborne,…

A longitudinal program of workshop-centered rehabilitation services was administered to mentally retarded adolescents. Results with the 36 remaining at the end of the 3rd year indicated that most characteristics central to vocational development were stable by early adolesence; a "competence cluster" of variables covaried systematically; high and…

The goal of this paper was to evaluate four alternative explanations to account for low feelings of political effectiveness and political trust among black school children. A discussion of research findings related to political efficacy and trust and a review of other pertinent research are followed by definitions of the basic concepts in the…

Criticizes approach to equal education that seeks equality of outcome as well as equality of opportunity. Discusses Spearman's theory of g that attempts to explain individual differences in intelligence. Contrasts efforts at genuinely reducing equality of outcome, including Aptitude X Treatment Interaction, Mastery Learning, and Thinking Skills…
