Excerpt from The Female Brain
Boys know how to employ this affiliative speech style, too, but research shows they typically don't use it. Instead, they'll generally use language to command others, get things done, brag, threaten, ignore a partner's suggestion, and override each other's attempts to speak. It was never long after Joseph's arrival on the playground that Leila ended up in tears. At this age boys won't hesitate to take action or grab something they desire. Joseph took Leila's toys whenever he wanted and usually destroyed whatever Leila and the other girls were making. Boys will do this to one another—they are not concerned about the risk of conflict. Competition is part of their makeup. And they routinely ignore comments or commands given by girls.
The testosterone-formed boy brain simply doesn't look for social connection in the same way a girl brain does. In fact, disorders that inhibit people from picking up on social nuance—called autism spectrum disorders and Asperger's syndrome—are eight times more common in boys. Scientists now believe that the typical male brain, with only one dose of X chromosome (there are two X's in a girl), gets flooded with testosterone during development and somehow becomes more easily socially handicapped. Extra testosterone and the genes in people with these disorders may be killing off some of the brain's circuits for emotional and social sensitivity.
