Until then, girls are on average always more mature than boys at any given chronological age. So comparing boys and girls, say, at age 10, is like comparing boys at age 10 and girls at age 12. Although in most cases girls act more mature at a certain age than boys, sometimes boys mature faster than other boys, and even faster than the girls. a 7 year hits the nail on the head when she talks about the differences between girls and boys. the researchers believe that the earlier reorganization in girls makes the brain work more efficiently, and therefore reach a more mature state for processing the environment.
