Black Intelligence Test of Cultural Homogeneity and Shipley-Institute of Living Scale Scores for Black Chicago Youths

Abstract

48 black teenagers living in the Douglas neighborhood of Chicago were given both the Black Intelligence Test of Cultural Homogeneity and the Shipley-Institute of Living Scale. Lower-class black subjects (housing project residents) scored below middle-class black subjects (high-rise apartment residents) on the vocabulary and abstract reasoning subtests of the Shipley but not on the Black Intelligence Test of Cultural Homogeneity. Scores on the latter increased directly with age, and females scored higher than males. When age was controlled for middle-class subjects Black Intelligence Test of Cultural Homogeneity scores were negatively related to vocabulary and when sex was controlled with lower-class subjects, scores were positively related to vocabulary. Abstract reasoning was negatively related to Black Intelligence Test of Cultural Homogeneity scores when age was controlled for all subjects.
