Louann Brizendine, MD has written "The Female Brain", "The Male Brain" and will soon have "The Upgrade" available. It will be released as a Kindle book on April 22. The female brain and the upgrade are both about brain structures and hormone effects on women and girls. I read that at one time scientists thought they knew the body's system but had not accounted for hormones. The book "Aroused" by Randi Hunter Epstein, MD discusses the basics of hormones.
The Female Brain explains that all babies are female at first but those destined to be male get an early testosterone bath. The dousing results in a brain structure that is less social and more ready for aggression. Brizendine also emphasizes the cognitive and emotional development of women to get high levels of pleasure from language and social interaction while males less so. Every hour, I see behavior in me and others that acts out exactly what Brizendine describes.
I can see what she writes about in myself. I tend to feel that "chit-chat" is 'frivolous' but not male kidding and punning. My stepfather asserted that I personally was clearly vaccinated with a phonograph needle, since I seemed quite talkative, notably so. That is not typical and sometimes, it isn't welcome. Dr. Brizendine writes:
Girls who expect their boyfriends to chat with them the way their girlfriends do are in for a big surprise. Phone conversations can have painful lulls while she waits for him to say something. The best she can often hope for is that he is an attentive listener. She may not realize he's just bored and wants to get back to his video game.
She continues:
This difference may also be at the core of the major disappointment women feel all their lives with their marriage partners—he doesn't feel like being social, he doesn't crave long talks. But it's not his fault. When he is a teen, his testosterone levels begin soaring off the charts, and he "disappears into adolescence," a phase used by one psychologist friend of mine to describe why her fifteen-year-old son never wants to talk to her anymore, takes refuge with his buddies in person or online gaming, and visibly cringes at the thought of a family dinner or outing. More than anything, he wants to be left alone in his room.
