Lewis, Andrew – Perspectives in Education, 2019
With the ascent of the National Party to power in South Africa in 1948, education reflected apartheid thinking and practices and implemented the ideology of separate development in educational institutions. Pronouncements of the African child's inferiority were reflected in government policy and legislation. The origins of this thinking and…

Sundet, Jon Martin; Eriksen, Willy; Borren, Ingrid; Tambs, Kristian – Intelligence, 2010
The aim of the study was to investigate the relationship between the Flynn effect and the effects of age differences between siblings on the intelligence difference between them. In Norway, the secular trends in intelligence-test score means vary both in magnitude and direction. We identified three periods: one period where the mean intelligence…

Lopez, Lorna M.; Mullen, William; Zurbig, Petra; Harris, Sarah E.; Gow, Alan J.; Starr, John M.; Porteous, David J.; Mischak, Harald; Deary, Ian J. – Intelligence, 2011
Intelligence is an important indicator of physical, mental and social well-being. In old age, intelligence is also associated with a higher quality of life and better health. Heritability studies have shown that there are strong genetic influences, yet unknown, on intelligence, including in old age. Other approaches may be useful to investigate…

Brunner, Martin – Learning and Individual Differences, 2008
This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

Gebauer, Guido F.; Mackintosh, Nicholas J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2007
The hypothesis that performance on implicit learning tasks is unrelated to psychometric intelligence was examined in a sample of 605 German pupils. Performance in artificial grammar learning, process control, and serial learning did not correlate with various measures of intelligence when participants were given standard implicit instructions.…

Sternberg, Robert J. – Intelligence, 1981
A three-stage model for the evolution of theories of intelligence is proposed and applied to understanding the evolution of correlationally based and experimentally based theories of intelligence. In stage one, alternative conceptions compete. In subsequent stages, alternative conceptions, which combine elements of prior approaches, emerge and…

Carroll, John B. – Intelligence, 1997
R. Herrnstein and C. Murray, in "The Bell Curve," stated six propositions concerning a "g" factor of intelligence. These propositions are found to be reasonably well supported in the scientific literature. These conclusions can be reached whether or not one accepts Herrnstein and Murray's claims about the social significance of…

Ceci, Stephen J. – Intelligence, 1990
The assumption that a singular biological resource pool embedded in the central nervous system results in differences in macrolevel outcomes because of the constraints it imposes on efficiencies of microlevel processing is refuted. Moderating effects on the causal pathways between microlevel and macrolevel performance are discussed. (SLD)

Haynes, Norris M. – 1995
Few books have generated as much controversy as the recently published "The Bell Curve: Intelligence and Class Structure in American Life." The tremendous polarization on the issue of the relationship between intelligence quotient (IQ) to race and social class, reinforced by the book, and the potential this book has for undermining…

Rushton, J. Philippe – Intelligence, 1989
Genetic influence was estimated on Wechsler Intelligence Scale for Children subtests from inbreeding depression scores calculated on cousin marriages in Japan (n=1,854 children) and correlated with American Black-White racial differences. The genetic contribution of racial differences in cognitive performance may be more robust than was previously…

Lim, Tock Keng – 1993
Confirmatory Factor Analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across male and female samples. Subjects were a stratified random sample of 234 male and 225 female 15-year-old students in Singapore attending Secondary 3 (the equivalent of grade 9). Four first-order factors were found…

Jensen, Arthur R. – Oxford Review of Education, 1991
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…
