Sex and age differences on the Raven's matrices.

This study examined the effects of sex and age on scores on a matrices test among university and college students aged 17 to 51 yr. Sex differences in mean scores were nonsignificant. The general decline with age was linear and negative, significantly so for women (n = 132), not for men (n = 74). Significant decrements occurred from the age of 26 yr. upwards for women only. The findings suggest that loss of intellectual capacity on the Raven's Matrices can be attributed to age.
