title: Homogeneity of effect sizes for sex across spatial tests and cultures: implications for hormonal theories.
abstract: Japanese and Canadian samples were compared on two spatial test which typically show higher male scores but tend to differ in the magnitude of the sex difference. Sex differences, both in terms of direction and magnitude, were similar between cultures. Results are discussed in terms of their relevance for hormonal theories of spatial sex differences.
