Abstract
INVESTIGATES WHAT EACH of the tests in a battery of 53 perceptual, cognitive, linguistic, and achievement measures was assessing in two socio-economic level (SEL) groups: upper-middle and low. Subjects were 211 second-grade boys and girls from the Atlanta Public Schools, approximately one third black and two thirds white from each SEL. Separate intercorrelation matrices and factor analyses were computed for the two SEL groups. Several well-defined factors common to both groups were found: immediate memory span, academic achievement, vocabulary, and four visual-perceptual factors. A separate auditory processing factor was found for the low SEL group and a verbal mediation factor for the upper-middle SEL group. The greatest similarity between the two SEL groups seemed to be in the visual factors and the greatest difference in the language factors. Implications were made about use of some of the tests and about teaching reading to Southern upper-middle and low SEL children.
