Studying a language later in life adjustments how the 2 halves of the mind contribute. As expertise enhance, language comprehension adjustments hemisphere specialization, however manufacturing doesn’t, in keeping with new analysis printed 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 best hemisphere can take over after an harm to the left. The precise hemisphere may 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 match neural exercise between hemispheres in grownup language learners whereas studying, listening, and talking of their native and new languages. Within the earlier phases of language studying, native and new languages seemed fairly related within the mind, however in superior learners, the 2 languages had been extra distinct. The native and new languages had 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 will likely clarify why it’s tougher to be taught to talk a brand new language as an grownup, despite the fact that it’s potential to be taught to grasp it fairly nicely.
