Socioeconomic Status and Levels of Ability.
Harris, Jerry D.
Major tenets summarizing Jensen's two-level theory of mental abilities were examined in a static-group comparison, correlational study. Caucasian siblings in grades one through four from low- and middle-socioeconomic (SES) populations were administered five Level I (associative learning ability) tasks and Raven's Progressive Matrices. Consistent with Jensen's theory, SES groups differed most on Level II (conceptual or problem solving ability) measures. However, predictions derived from Jensen's explanation of the phenomenon were not fulfilled. The functional dependence of II on I and the stronger relation of I and II in the middle-SES population were not supported. The pattern and strength of relationships among Level tasks were not suggestive of a relatively homogeneous class of performances or ability. (Author/RC)
