Hoorn Warnings and Dangers

Men Are from Mars, Women Are from Venus, the catchy title of the 1992 bestseller by John Gray, succinctly expresses an ancient dilemma. What--if anything--do men's and women's brains do differently?

The general statement that men and women respond and behave differently under the same circumstances is true; For example, from the crib, male babies tend to be more aggressive and females more passive. As adults, in spatial operations, men have the edge in such skills as negotiating a maze, reading a map, and quickly discriminating between right and left. Men also perform better than women when asked to visualize an object and imagine rotating it. On the other hand, women tend to perform better than men when asked to look at objects of different shapes, sizes, and colors, and then to group them in some order.

This still doesn't explian why my female co-driver turns the map all around when I'm asking for the road to travel, while I like the map at one point so I can better visualize our position. Help!
