The YouTube video called “The benefits of a bilingual brain-Mia Nacamulli” is about the bilingual brain, how it develops and how it can benefit our lives. One interesting quote found in the video was “The heightened workout a bilingual brain receives through its life can also help delay the onset of diseases, like Alzheimers’s and dementia by as much as 5 years.” Through this video, I learned that there are three types of bilinguals which consist of the compound bilingual, the coordinate bilingual and the subordinate bilingual. The compound bilingual learn two languages from an early age, the coordinate bilingual learns two languages in two contexts such as home and school, and the subordinate bilingual learns a second language by filtering it through their primary language. Also, being bilingual used to be seen as a learning handicap but newer research shows that the frequent switching of the brain between the two languages causes a strengthening of the dorsolateral prefrontal cortex, which helps with problem-solving.
This resource is useful as it provides a brief overview of the bilingual brain, which helps me answer the questions on how the bilingual brain develops and what are some of the benefits that are not just social but also relating to our brain development.
