Relationships between salivary estradiol and components of mental rotation in young men.
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.
