Title: The ups and downs of a teenage brain.
Date: November 2011
The ups and downs of a teenage brain proves that what scientist thought about a
person’s IQ never changing, is probably not true. In this study, neuroscientists from
The University College London, used 33 teenagers from ages 12-16 years old and
gave them and IQ test and also took and MRI of their brain (which is a picture).
They started the study in 2004 and then three or four years later they brought back
the same 33 students. When the students came back they took another IQ test and
had another picture of their brain taken.
This study found that a teen’s IQ can change. They found that some IQs got higher
and some got lower. Along with the change in IQ scores, the scientists also found
that the gray matter in some of the teens brains had increased, which means more
brain cells. The scientists think that a possible reason for the increase in IQ, could
be from socializing and sports.
I think this article is interesting that some of the IQs went up and some went down,
when they thought they wouldn’t change. I was fun to learn about new facts and
