Sex differences on the progressive matrices: A meta-analysis.

  title={Sex differences on the progressive matrices: A meta-analysis.},
  author={Richard John Lynn and Paul Irwing},
A meta-analysis is presented of 57 studies of sex differences in general population samples on the Standard and Advanced Progressive Matrices (SPM and APM, respectively). Results showed that there is no difference among children aged 6–14 years, but that males obtain higher means from the age of 15 through to old age. Among adults, the male advantage is 0.33d equivalent to 5 IQ points. These results disconfirm the frequent assertion than there are no sex differences on the progressive matrices… Expand
