Sex differences on the progressive matrices: A meta-analysis

Research output: Contribution to journalArticlepeer-review

Abstract

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 0.33 d equivalent to 5 IQ points. These results disconfirm the frequent assertion than there are no sex differences on the progressive matrices and support a developmental theory that a male advantage appears from the age of 15 years. A meta-analysis of 15 studies of child samples on the Colored Progressive Matrices showed that among children aged 5-11 years boys have an advantage of 0.21 d equivalent to 3.2 IQ points. © 2004 Elsevier Inc.
