Fascinating. Many thanks.
Anne Moir has written about this in "Brainsex" and "Why men don't iron".

Incidentally the multi-tasking capabilities are more complicated than "Women good, men bad". For example something like simultaneous map reading and talking is an example of where men outperform women. Apparently with this combination of tasks it's an advantage to be more specialised and use more distinct parts of the brain for different tasks.
