Studying a language later in life modifications how the 2 halves of the mind contribute. As abilities enhance, language comprehension modifications hemisphere specialization, however manufacturing doesn’t, in accordance with new analysis revealed in JNeurosci.
The 2 sides of the mind do not evenly cut up labor for each perform. In most individuals, language depends on the left hemisphere, however the precise hemisphere can take over after an harm to the left. The correct hemisphere may also contribute when studying a brand new language, making it unclear if the left hemisphere is definitely specialised for language.
Gurunandan et al. used fMRI to check neural exercise between hemispheres in grownup language learners whereas studying, listening, and talking of their native and new languages. Within the earlier levels of language studying, native and new languages seemed fairly related within the mind, however in superior learners, the 2 languages have been extra distinct. The native and new languages have been capable of recruit reverse hemispheres for comprehension however talking both language remained reliant on the left hemisphere. These outcomes recommend manufacturing is hard-wired to the left hemisphere, whereas comprehension is extra versatile.
This may increasingly clarify why it’s harder to be taught to talk a brand new language as an grownup, although it’s potential to be taught to grasp it fairly nicely.
