Are You Pre-Wired to Be Bilingual?
Some brains appear to be pre-wired to acquire a second language, according investigators who analyzed MRI scans of native English speakers who were asked to study Chinese vocabulary for six weeks. The pre-study MRI scans of those who were most successful at learning Chinese revealed a greater number of neural connections in the areas of the brain associated with some thinking and language skills. Study co-author Dr. Ping Li adds that, “[The brain] becomes more connected and integrated after learning [but] the brain networks of the more successful learners are better connected even before learning takes place.” It’s not yet clear what percentage of people are pre-wired to excel at learning a second language, and it’s not known if training can improve this type of brain wiring.
