  • RICHARD LYNN (a1), EDUARDO BACKHOFF (a2) and L. A. CONTRERAS (a2)

Abstract

Raven’s Standard Progressive Matrices test was administered to a representative sample of 920 white, Mestizo and Native Mexican Indian children aged 7–10 years in Mexico. The mean IQs in relation to a British mean of 100 obtained from the 1979 British standardization sample and adjusted for the estimated subsequent increase were: 98·0 for whites, 94·3 for Mestizos and 83·3 for Native Mexican Indians.
