Japanese Inbreeding Depression Scores: Predictors of Cognitive Differences between Blacks and Whites.
Peer reviewed Peer reviewed
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…

Correlations of Mental Tests with Each Other and with Cognitive Variables Are Highest for Low IQ Groups.
Peer reviewed Peer reviewed
Detterman, Douglas K.; Daniel, Mark H. – Intelligence, 1989
Two studies (N=4,261 persons) illustrate an inverse relationship between ability level and correlations among IQ measures. Low IQ subjects showed higher correlations than did high IQ subjects. Intercorrelations of IQ subtests, intercorrelations of cognitive ability measures, and correlations of IQ with measures of cognitive ability displayed the…

Forward and Backward Digit Span Interaction with Race and IQ: A Longitudinal Developmental Comparison.
Jensen, Arthur R.; Osborne, R. Travis – 1979
Longitudinal data on the auditory forward and backward digit span (FDS and BDS) subtests of the Wechsler Intelligence Scale for Children (WISC) were obtained at five age levels (between 6 and 13), in samples of white and black children. Factor analysis and analysis of variance of the data were conducted to test 5 hypotheses, related to Jensen's…
