title: Relationships between salivary estradiol and components of mental rotation in young men.
abstract: Testosterone and estradiol levels were measured by saliva assays in 15 young men, and their relationships with different processes in a mental rotation task were elucidated. The estradiol level was positively correlated with reaction time; this effect was yielded by the slope of functions relating performance to angular disparity. These findings suggest that estrogen may inhibit the performance of a mental rotation task by affecting perception of the rotation process.
