Visual spatial skills : It is accepted that high levels of prenatal testosterone encourage development of the right side of the brain, which would also encourage the visual spatial skills important in science. Brosnan’s findings appear to contradict this, with a more "female" pattern found in the scientists studied.
The researchers therefore speculate that exposure to either unusually high or low levels of testosterone in male fetuses could lead to a "scientific" brain. From this it would follow that average levels of hormone exposure could lead to a "social science" brain. http://www.newscientist.com/news/news.jsp?id=ns99996564
