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.
本研究考察了15至19岁以及55至93岁这5个年龄组中，黑人和白人受试者在霍恩的Gf-Gc理论所涉及的6种能力上的差异（白人受试者共956名，黑人受试者共128名）。白人受试者在所有6种能力上的得分均显著更高，但在流体推理、短期理解与提取方面的差异小于0.5个标准差。年龄与种族的交互作用不显著，这表明黑人和白人受试者得分之间的差异不会随年龄而变化。
