Past literature shows that the brain regions involved in the understanding and production of verbal languages are the same brain regions that allow one to communicate in sign language. Brain lesion studies have con.finned that both spoken and signed language rely on a common system of neural and cognitive mechanisms. Further research has con.finned that by acquiring sign language skills at a young age, children have the advantage of enhanced cognitive processes pertaining to language, spatial reasoning, and attention. Future research could be conducted regarding the advantages that sign language acquired early in life could have on minimizing both the learning and attention disabilities in hearing and deaf children.
