Spatial Ability, Handedness, and Human Sexual Orientation

Psychoneuroendocrinology. 1995;20(5):487-97. doi: 10.1016/0306-4530(94)00075-l.


We investigated the relations among mental rotations and spatial perception abilities, handedness, and sexual orientation in both men and women. The present study included a relatively large sample and attempted to control statistically for important covariates such as general intelligence. Significant sex differences were obtained for mental rotations and spatial perception, but not for handedness. None of these measures was significantly related to sexual orientation within either sex.
