In one, scientists dressed newborns in gender-neutral clothes and misled adults about their sex. The adults described the "boys" (actually girls) as angry or distressed more often than did adults who thought they were observing girls, and described the "girls" (actually boys) as happy and socially engaged more than adults who knew the babies were boys. Dozens of such disguised-gender experiments have shown that adults perceive baby boys and girls differently, seeing identical behavior through a gender-tinted lens. In another study, mothers estimated how steep a slope their 11-month-olds could crawl down. Moms of boys got it right to within one degree; moms of girls underestimated what their daughters could do by nine degrees, even though there are no differences in the motor skills of infant boys and girls. But that prejudice may cause parents to unconsciously limit their daughter's physical activity. How we perceive children-sociable or remote, physically bold or reticent-shapes how we treat them and therefore what experiences we give them. Since life leaves footprints on the very structure and function of the brain, these various experiences produce sex differences in adult behavior and brains-the result not of innate and inborn nature but of nurture.

Deak is a psychologist and author of "Girls will be Girls." She lectures around the world about sex and gender. And she's on the board of the Seattle Girls' School. She spoke mostly about adolescence, which she called the magic decade, because there are "things going on that didn't happen before and that won't happen again," she said. I called her office in Ohio and she explained that the amygdala, the part of the brain that deals with emotions, swells, which makes all teens more sensitive and volatile. At the same time, the prefrontal cortex stops functioning well. That's the part that controls higher functions, like judgment. Hormones keep teens from falling asleep when parents say they should and make it difficult for them to wake up at hours dictated by school schedules. The single most profound difference we could make on education, Deak said, would be to let teens sleep on nature's schedule (midnight to 9 a.m. or later).
