A Twin Study of Gender-Influenced Individual Differences in General Cognitive Ability.
Knopik, Valerie S.; Defries, John C.
Intelligence, v26 n2 p81-89 1998
To study whether individual differences in general cognitive ability differ in males and females, full-scale IQ data from 426 child twin pairs were fitted to a structural equation model of sex limitation. Individual differences in general cognitive ability appear to be substantially due to common genetic influences in males and females. (SLD)
