I was referring to mental rotation ability, I clarified it in an edit.

I also don't have time to go into the studies you linked about general differences but similar studies have been debunked before. For example with 1.5 day old infants where the experimenters knew about the sex and their bias subtly corrupted the experiment and it did not reproduce when the bias was truly accounted for.
