Sex differences are reported for samples of approximately 1000 16-year-old blacks, Indians and whites in South Africa on ten tests of cognitive ability. Males obtained significantly higher means on non-verbal reasoning, spatial and mechanical aptitude, and females obtained significantly higher means on perceptual speed and memory for meaning (except among the black sample). In general the sex differences in South Africa are consistent with those typically obtained in the United States.
