When we think someone is smart,we say they have a big brain.But are there any facts to prove that statement?
Yes ! In a new study done by Michael McDaniel , a psychologist at Virginia Commonwealth University,bigger does mean smarter."For all ages and sex groups,"he says,"it is now very clear that intelligence has something to do with brain volume(容量)."
McDaniel reached his conclusion after measuring the size and volume of 26 brains with the help of some instruments.He then used standard IQ tests to measure the intelligence of the owners of these brains. But do IQ tests really reveal intelligence?McDaniel believes that they do,and here are other studies to backup that point of view.One study last year found that IQ is related to the amount and distribution(分布) of gray matter in the brain.The study showed that the amount of gray matter in certain places was strongly related to high IQ.The distribution of gray matter in the brain,which is different for different people,could explain why one person with a high IQ is good at math but poor at spelling,while someone else with the same IQ has just the opposite ability.
Yet another recent study found that women have more gray matter(compared with white matter) than men!However,the study also showed that in the areas of the brain specifically(特别地) related to intelligence,men had much more gray matter,which is needed for some tasks,such as doing a math problem.Women ,on the other hand ,had more white matter ,which is necessary for collecting information.And the point is that intelligence can be influenced in different ways.
"On average,"McDaniel says,"smarter people learn more quickly,make fewer mistakes,and are more productive."He believes in the use of IQ tests to examine those who want to find a job.So,be well,do good work,and…exercise that brain!
