And that, heterosexual females dilated a lot more firmly with the reduced stimulating sex than just did heterosexual men, p = .01, d = step one.00.
Consistency around the Steps

The typical pure relationship is actually.64 inside the guys and you can.55 in women. A continual strategies t-sample, having computed gender differences in correlations in this sets from parameters, ideal your magnitude away from natural correlations are significantly more powerful for the men than simply girls, t(20) = eight.83, p Desk 2 ). Almost every other research has stated corresponding sex differences , .
