Neuroscience and the Bilingual Brain | Edutopia

Neuroscience and the Bilingual Brain | Edutopia:




A selective attentive focus and the ability to block out distraction are seminal executive functions that are minimally developed in youngsters. These functions gradually become stronger throughout the years of prefrontal cortex maturation, which last into the twenties. It is with regard to these executive functions that research about the "bilingual brain" is particularly exciting.
The research refers to children raised with a language at home that differs from the dominant language outside the home, such as in school. Compared to monolinguals, the bilingual children develop greater attention focus, distraction resistance, decision-making judgment and responsiveness to feedback. The correlated fMRI scans of these children reveal more activity in the prefrontal cortex networks that control these executive functions.
