It's pretty obvious why men at better are spatial cognition tests. Men were the primary hunters and needed to navigate complex spaces with little reference points away from camp for days a time. Because of this, there was probably a strong selection pressure for men to be good at hunting. Those who were the best at it and didn't get lost were rewarded with increased female reproductive access.
