title: Examining the interaction of age x race pertaining to black-white differences at ages 15 to 93 on six Horn abilities assessed by K-FAST, K-SNAP, and KAIT subtests.
abstract: This study examined differences between black and white subjects on 6 abilities from Horn's Gf-Gc theory for 5 age groups between 15-19 and 55-93 years (total ns = 956 white and 128 black subjects). White respondents scored significantly higher on all 6 abilities, but differences on fluid reasoning and short-term apprehension and retrieval were less than .5 SD. Interactions of age x race were nonsignificant, indicating that the discrepancies between scores of black and white subjects did not vary as a function of age.
