They excel in verbal fluency and comprehension. They tend to talk better, argue more persuasively, and learn foreign languages more easily than males do. They are better at expressing their feelings in words, and they are even better equipped to sing in tune. The relative advantages of each sex do shift over time. For example, girls develop verbal abbility much more rapidly than boys in infancy, but boys more or less catch up between the ages of 4 and 11.
Later girls get another boost and take the lead during their late teens and early twenties.
Boys don't begin to demonstrate their superiority in mathematical skills unntil adolescence. Prior to the 6 th or 7 th grade, mathematics achievement is about the same for both sexes. The corpus callosum is the central station for messages between the left and right hemispheres, and the bulge turned out to be an extra bundle of neurons that was missing in male brains. The researchers reasoned that females have a greater capacity to integrate the activities of the two sides of the brain, than do males. There is no research evidence which indicates that girls learn best from female role models.
