The Sex by Race Interaction in Cognitive Measures.
Humphreys, Lloyd G.; And Others
Data consisting of more than 80 cognitive measures from Project TALENT for 100,000 white and black students was analyzed for possible race by sex interactions. Control variables included geographical area, grade in high school, and socioeconomic class. Race-by-sex interactions were largest when socioeconomic class was controlled, and were highly related to the size of the main effect of sex as well. White boys and girls differed more than black boys and girls regardless of whether the overall sex differences favored males or females. Sex-by-grade and, to a lesser extent, sex-by-area interactions were also moderately large and consistent with the size of the sex main effect. Because there were no consistent relationships with other main effects, and because the measures producing sex differences also tended to produce the interactions, it was concluded that sex differences and the interactions with sex share the same causes. Differences between these results and those of Jensen were also discussed. (Author/PC)
