Performing in sign language & speaking in words uses the same area of the brain, says study
A recent study by New York University says that speaking verbally and performing sign language require the same parts of the brain. This is the first time that a study has brought out the association between these two forms of communication.
Researchers say that the neural skills needed to perform sign language are like the skills required to speak a sentence out loud.
The study says that despite the significant differences between verbal and sign language, the same part of the brain is used for both.
The study was conducted on two groups of people. One was a group that was familiar with American Sign Language. The other was a group of people who knew English and could speak and hear.
The ASL signers and the English speakers were shown the same pictures. Both groups named them using semantically identical expressions.
