Level I and Level II Abilities in Three Ethnic Groups.
Jensen, Arthur R.
A large battery of various tests of intelligence, scholastic achievement, and short-term memory was administered to some 2,000 white, black, and Mexican American pupils in grades 4, 5, and 6 in a largely agricultural school district in the central valley of California; the 3 grades were used as separate replications. Factor analysis with oblique rotation yielded three main factors, identified as fluid intelligence, crystalized intelligence, and a memory factor. Mean factor scores for the three ethnic groups differed significantly. The white and black groups differed markedly in fluid and crystalized intelligence but not in memory; the white and Mexican American groups differed markedly in fluid, but much less in crystalized intelligence and memory. The black and Mexican American groups differed the most in fluid but only slightly in crystalized intelligence. There were also systematic ethnic group differences in the pattern of intercorrelations among factor scores, and in the correlations of the factor scores with an index of SES. The results are discussed in relation to Jensen's two-level theory of mental abilities and Cattell's theory of fluid and crystalized intelligence. (Author)
