When Karl KIM immigrated to the United States from Korea s a teenager,he had a hard time learning English.Now he Speaks it
fluently,and he had a uniqe opportunity to see how our brains adapt to a second language. As a graduate student,Kim worked in the lab of joy Hirsch, a neuroscientist in New York .their work Led to a important discovery,They found evidence that children and adults don”t use the same parts of the brain when they learn a second language
The researchers used an instrument called an MRI scanner to study the brains of two groups of bilingual people .One group Consisted of those who had learned a second language as children.The other consisted of people who ,like Kim,leaned their second language later in life. People from both groups were place inside the MRI scanner. This allowed Kim and Hirsch to see which parts of the brain were getting more blood were active. They asked people from both groupa to think about what they had done the day bdfore,frist in one language and then the other.they couldn’t s speak out loud because any movement would disrupt the scanning.
KIM and Hirsch looked specifically at two language cetera in the
brain ….KIM and Hirsch found that both groups of people used the same part of Wernick’s area no matter what language they speaking. But their use of Broca’s area was different.
People who learned a second ….How does Hirsch explain this difference?.....the processing of a new language must be taken over By a different part of the brain.
A second possibility…….And that is very different from learing a language in a high school or college class.
