In addition to ethnic origin, the subjects were further grouped by social class, middle and lower only. Social Class was a more important factor than ethnic origin in WISC differences; and, nonverbal ability differences (Cohen factors) were found to relate only to S's membership in a particular social class."

A critique arguing: (1) that the assumptions underlying the use of intelligence tests are invalid; (2) that findings regarding individual differences can not be generalized to differences between populations; and, (3) that the studies cited as evidence were both incorrectly designed and improperly executed. (JM)

Reviews Richard Herrnstein's article and book concerning I.Q. and argues that the questions of the nature of intelligence and the respective influences of environment and heredity are important not just in the interpretation of statistical evidence but because these questions have implications in the lives of human beings. (Author/JM)

By nonintellective" are meant factors which are present in a test situation and which influence the test scores obtained but are not obviously related to the skills or knowledge ostensibly being measured by the test. (Authors)

The purposes of the study to determine psychometric characteristics of the Series Learning Potential Test, the effects of Learning Potential training on Series scores, and the relationship of Series scores to IQ, race, social class, and reading achievement. The Series Test was administered to students in 79 classrooms in five Connecticut towns…

IQ tests and intelligence were discussed from an evolutionary perspective and implications concerning legal decisions and social policy were presented. It was concluded that disproportionate social and economic benefits need not result from the use of IQ tests in the selection of educational and occupational elites. (RD)

A within cultural comparative examination of three samples of school-children residing in Saskatchewan, South Australia and Nova Scotia enabled the effects of family size and socioeconomic status on measured intelligence to be ascertained. Samples of schoolchildren in Regina (Canada), Adelaide (Australia) and Sydney (Canada), divided into…

In this address, Jensen discusses his views on the effects of heredity and environment on human intelligence, in an attempt to clarify his original statements on this subject. Since his article appeared in the "Harvard Educational Review" in 1969, the term "Jensenism" has accrued a variety of meanings through popular usage (according to Jensen)…

While debates over the heritability of IQ and the potential for culture bias in measuring instruments have generated much research and public comment, it is also possible to investigate the significance of interracial differences in mean IQ by ignoring both the foregoing issues and instead examining the social psychology of the test situation…

Noting that many of the attacks on individual scientists as well as some of the attacks on the field of behavior genetics are more than intemperate--they are non-rational--the author discusses his experience as a signatory to a document drawn up by Ellis B. Page during the winter of 1971-1972. The intent of this controversial document was to…

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…

Once again intelligence tests are being used as the major basis to establish the genetically determined limitations of minority and economically disadvantaged groups. By reviewing the arguments regarding the I.Q. test and the hereditability of intelligence, the author compares these with two sets of phenomena: the I.Q. test scores and the…

Gottesman, professor of psychology, University of Minnesota; Arthur R. Jensen; and Jane R. Mercer, associate professor of sociology, University of California, Riverside; (2) such…

It has been said that the heritability of learning ability or of intelligence is irrelevant to teachability. In support of this statement we see it pointed out that a child or a group of children show some response to training, and this is held up as evidence against the heritability of intelligence or learning ability. Most estimates of the…

This document comprises three presentations made on March 23 at a symposium sponsored by the Southern Regional Council focusing on Human Intelligence, Social Science and Social Policy.
