Scientists identify why girls often mature faster than boys. For example, autism spectrum disorders are almost 5 times more common among boys (1 in 54) than among girls (1 in 252). girls really do mature quicker than boys, scientists find girls brains can begin maturing from the age of 10 while some men have to wait until 20 before the same organisational structures take. Mainly, because maturity as a trait, has for long been envisioned, only after a girl or a boy reach a certain age that is 12 or 13, which is also the age when they hit puberty. So, get the point why we say, early puberty in girls than boys is an important factor reasoning why women mature faster than men. Stop using the excuse that boys mature slower than girls for bad behaviour rebecca reid monday 541 pm share this article via facebook share this article via twitter share this. On average, girls are potty trained earlier than boys, though its unclear whether this is due to physical or social differences. (moms usually do the training, and it may be easier for a girl to identify with someone of the same gender.). its always been conventional wisdom that girls reach maturity more quickly than boys, but now scientists have provided some proof. In new research published in the journal cerebral cortex, an international group of researchers led by a team from newcastle university in england found that girls brains march through the reorganization and pruning typical of normal brain development earlier. But i would say the personal development how fast it happens depends on the individual and it can not be generalized, since we are talking about. A 2013 study published in cerebral cortex offers a scientific explanation behind the common notion that men take longer to act their age than women do. Boys have a slower rate of maturation in the respiratory and immune systems before birth making them more susceptible to illnesses in the early years. Boys brains are about 9 larger than female brains, but girls mature at a physiologically faster rate up to puberty. More boys than girls suffer fetal distress during the birth process and.
