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.

Elective off premises activities of 65 functionally mobile patients in two nursing homes were studied for a six-month period. More intact patients engaged in a greater frequency of off premises outings. Thus, in-house recreational activities in a long-term care setting should be geared to the more deprived intellectually impaired patient…

Lower class black and lower class white first-grade children learned an unorganized and an organized list of words to test Jensen's hypothesis of racial differences in mental abilities. Both groups of children performed significantly better on the organized list with comparable means for each list. Most of the predicted relationships were not…

Quantitative racism is defined as the intentional or unintentional misuse of statistical and quantitative methods to show some kind or type of ethnic superiority, usually with respect to black-white differences. This essay identifies some fallacious applications of statistical methods common to a number of recent studies in the behavioral…

This paper examines the implications of recent theory and research in cognitive psychology for the understanding and assessment of intelligence. Three major themes are developed. The first has to do with how changes in the social and educational climate for testing can influence the conception of intellectual compentence and the technology of…

The author reexamines the controversy surrounding his genetic hypothesis in an attempt to clarify his contention that differences in IQ scores between blacks and whites may be attributable as much to heredity as environment. (EH)

Examines the definitions of intelligence and educability and discusses these terms in relation to the writings of Jensen and of Darlington. (PEB)

This paper offers a detailed review of the literature concerning sex differences in the learning of mathematics. It identifies cognitive, affective and educational variables which have been either shown or hypothesized to contribute to sex-related differences in mathematics learning. The author analyzes each study in detail. One important finding…

Intelligence is related to executive performance though different kinds of executive work seem to require differing intellectual abilities. To examine these different intellectual functions and their relationship to performance ratings, 208 male executives completed the School and College Ability Test (SCAT), the Abstract Reasoning Test, and three…

Developmental and individual differences in mathematical aptitude were investigated as a function of knowledge structure and processing variables. Results indicated the relative importance of knowledge structure and strategy skills in aptitude test performance. Protocol data further elaborated the interrelationships between knowledge and process…

THE DATA FROM PREVIOUS STUDIES WERE USED TO DETERMINE IF THERE WERE DIFFERENTIAL NONINTELLECTUAL (PERSONALITY) CHANGES IN YOUNG ADULTS WHO DIFFERED MARKEDLY IN MEASURED ACADEMIC APTITUDE. THREE OF THE FORMER STUDIES WERE FOR A 2-YEAR TEST AND RETEST TIME PERIOD, AND TWO WERE FOR A 4-YEAR TEST AND RETEST TIME PERIOD. COMPARISONS OF NONINTELLECTUAL…

Ronald C. Johnson argued that if early environmental stimulation or deprivation has a significant effect on intellectual ability, then individuals who are genetically identical and who are exposed to a common early environment should resemble one another more closely in IQ than similar individuals who have not shared a common environment. Johnson…
