Scientists are using the latest tools of genetics and neuroscience to explore deep-rooted behavioral differences between the sexes. They report significant difference in the structure and functioning of male and female brains in both humans and animals. One example given in the article is a computerized maze-searching experiment done at Wayne State University . Scott Mowatt, a psychologist, said it took females five minutes longer than males to find their way to a goal. But an experiment at the National Institutes of Mental Health found that women outperformed men in a test of verbal fluency. The news story ran widely today in Knight Ridder newspapers across the country.
