the reason they called it teen brain is not because it's underdeveloped but because it's the brain of someone in teenage years. when they get older (21) it's not a teen brain anymore but an adult brain. that doesn't mean it has to be a fully/normally developed brain there are indeed other factors that come to mind when this happens like extra chromosomes/ missing neurons/ or other complications. but that's the reason they called it teen brain though.

and as i said maybe the writer of the acticle didn't take in mind that people might miss interperate his/her writing. just because it's written on a scientific page doesn't mean the scientists themselves wrote it, just like we aren't the writers of another....sadly....

as for the enviroments. yes living in different places might bring different behavior but it won't vary much from that of the rest of the world. usually these 'tests' are executed globaly not just in america or europe or asia. this test is done globally since it's not a european article yet dutch articles state the same. it's part of how tenagers grow. wether it be in asia, america or europe it's the same everywhere. race doesn't matter either as is stated in other articles. it's like how people get a lower voice or facial hair over a certain period of time. some people grow allot of hair some people barely. some people have a very low voice some people barely change at all. it's all part of the body changing over time which may vary a bit from person to person. but eventually it follows a certain path that is the same for everyone. infant-child-teen-adult (roughly put together) and every stage brings certain changes to the body.

therefore 8 year old children don't have huge bears as teenagers don't have certain neurons in the brain yet. that is something that starts developing at around 18-20 it's all part of growing up.
