Denne undersøgelse analyserer kønsforskelle i rumlige evner gennem en meta-analyse af 286 effektstørrelser. Resultaterne viser, at der er betydelige kønsforskelle i flere tests, men også variation mellem testene. Der er delvis støtte til, at størrelsen på forskellene er faldet over tid, og at tidspunktet for, hvornår forskelle opstår, afhænger af testen.

Magnitude of Sex Differences in Spatial Abilities: A Meta-Analysis and Consideration of Critical Variables.

Hele abstrakt på originalsprog:
In recent years, the magnitude, consistency, and stability across time of cognitive sex differences have been questioned. The present study examined these issues in the context of spatial abilities. A meta-analysis of 286 effect sizes from a variety of spatial ability measures was conducted. Effect sizes were partitioned by the specific test used and by a number of variables related to the experimental procedure in order to achieve homogeneity. Results showed that sex differences are significant in several tests but that some intertest differences exist. Partial support was found for the notion that the magnitude of sex differences has decreased in recent years. Finally, it was found that the age of emergence of sex differences depends on the test used. Results are discussed with regard to their implications for the study of sex differences in spatial abilities.
