The results from this study may help explain why men and women excel at different types of tasks, said co-author and neuropsychologist Rex Jung of the University of New Mexico. For example, men tend to do better with tasks requiring more localized processing, such as mathematics, Jung said, while women are better at integrating and assimilating information from distributed gray-matter regions of the brain, which aids language skills. This in no way means women can't be as good (or better) at tasks requiring "localized" processing. It just means that our brains have evolved differently. It's fantastic. I realize that "infants understand more than they are able to vocalize". I am around two 9 month old kids every day. My daughter talks equally to both my wife and myself. I don't see her "mimicking" one more than the other. Her brain is just engineered differently than the little boys, by design. It's not better/worse, it just is. (actually.. I think it's better but I'm very biased) btw, my wife is fantastic at math and is FAR better at "localized processing" than I am. I am much better with language etc. -So anomalies do occur. source: http://www.livescience.com/3808-men-women-differently.html
