Understanding Bilingualism and Its Cognitive Effects

The video explores the cognitive and neurological impacts of bilingualism, highlighting the different types of bilinguals: compound, coordinate, and subordinate. It discusses how language learning affects brain hemispheres, with children using both hemispheres and adults typically using one. Bilingualism offers cognitive benefits, such as increased grey matter density and delayed onset of Alzheimer's. Historically seen as a handicap, modern research shows bilingualism enhances brain function, particularly in the dorsolateral prefrontal cortex, aiding in problem-solving and task-switching.

What is one of the benefits of being bilingual mentioned in the introduction?

What does the critical period hypothesis suggest about language learning?

• Language learning is not affected by age

• Language learning is only possible in childhood

• Children can use both brain hemispheres for language acquisition

• Adults learn languages more easily than children
