Gillborn, David – Peabody Journal of Education, 2018
Derrick Bell's thesis, that racism is a permanent feature of society, is frequently misrepresented by detractors as signaling a view of racism as monolithic--bold, obvious, and unchanging. This paper argues that critical race theory [CRT] reveals a very different understanding of racism as relentless, yet fluid, and quick to morph depending on…

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…

Gelade, Garry A. – Intelligence, 2008
This paper examines the distribution of national IQ in geographical space. When the heritability of IQ and its dependence on eco-social factors are considered from a global perspective, they suggest that the IQs of neighboring countries should be similar. Using previously published IQ data for 113 nations (Lynn, R., & Vanhanen, T., (2006). IQ and…

Bridgett, David J.; Walker, Michael E. – Psychological Assessment, 2006
Although attention has been given to the intellectual functioning of children with attention-deficit/hyperactivity disorder (ADHD) relative to their non-ADHD peers, few studies have examined intellectual functioning in adults with ADHD. The purpose of the current investigation was to examine differences in intellectual ability between adults with…

Templer, Donald I.; Arikawa, Hiroko – Intelligence, 2006
The impetus for our study was the contention of both Lynn [Lynn, R. (1991) "Race differences in intelligence: A global perspective." "Mankind Quarterly," 31, 255-296] and Rushton [Rushton, J. P. (1995). "Race, evolution and behavior: A life history perspective." New Brunswick, NJ: "Transaction"; Rushton, J.…

Jensen, Arthur R. – 1981
The specificity doctrine, holds that psychometric tests measure nothing other than the specific bits of knowledge and learned skills reflected in the item content of the tests. This prevailing doctrine has influenced the interpretation of test scores and the conceptualization of test validity, as well as the practical use of tests in educational…

Lynn, Richard; Longley, David – Intelligence, 2006
A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…

Jensen, Arthur R. – Intelligence, 1981
The Ramey and Haskins intervention experiment is examined. Narrow transfer of training from cognitive intervention techniques to IQ test performance in early childhood, rather than enhancement of the g factor itself, is hypothesized as a cause of the typical fadeout of early IQ gains in later childhood.

Nettelbeck, Ted; Wilson, Carlene – Intelligence, 2004
Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

Chipuer, Heather M.; And Others – Intelligence, 1990
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)

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…
