The research focuses on the study of laterization changes

The research focuses on the study of the laterization changes of brain functions during the performance of different linguistic tasks such as reading, speaking or listening in the native language in comparison with a foreign language that that person was learning.

One of the “main findings” is the demonstration that the left hemisphere “is key to speaking, reading and listening in the native language”.

However, when an adult learns another language, “this condition remains in speech,” while for reading and listening comprehension, “resources from both hemispheres of the brain are recruited,” said BCBL researcher Kshipra Gurunandan.

“This may explain why it is more difficult to learn to speak a new language than to understand it at a very high level. More brain resources are used for oral and written comprehension than for speech ”, he indicated.

According to the study, in the early stages of foreign language learning, language systems activate the same brain region (left hemisphere), but as competence in the new acquired language increases, changes in reading comprehension and learning are observed. auditory, which do not occur in speech.

Research has revealed that language learning in adulthood is associated with the brain’s ability to transform itself into the field of language understanding, but not for production or speaking.

“These results also help to better understand how language is organized in the brain and what the consequences can be on the different linguistic systems of an accident, trauma or disease that affects a specific brain area, as well as its possible recovery” Gurunandan pointed out.

The study, which has been published in the prestigious scientific journal “The Journal of Neuroscience”, has lasted for 7 years and has had the participation of 50 volunteers between 17 and 60 years old.
