The Bilingual Brain

I have recently completed a certificate course on Coursera site called “The Bilingual Brain”. The course talked about the latest research related to how humans learn one or two languages and other cognitive skills. The course was very interesting, and I would like to share some interesting facts I learned in the course.

· Bilingual infants have a bias toward speech sounds from 2 languages at an early age.

· Studies have found that bilingual children can distinguish between the grammars of two languages by the age of 4.

· ASL (American Sign Language) can lead to better grammatical error judgment depending on the age of exposure.

· Perceptual expertise leads to the presence of inversion effects for faces, wholistic processing of cars in car experts, and wholistic processing of birds in bird experts

· Bilingual researchers have considered shared aspects of across languages which is like thinking about shared motions used in soccer, tennis, and baseball.
