Learning a Second Language May Depend on Brain’s Connections
According to a study recently published in the Journal of Neuroscience, learning a second language is easier for some adults than others, and innate differences in how various parts of the brain communicate with each other may help explain the reason why. To study this, the group at the Montreal Neurological Institute scanned the brains of 15 adult English speakers who were about to begin an intensive 12-week French course, and then tested their language abilities both before and after the course. Using resting state fMRI, the researchers examined the connectivity within the participants’ brains prior to the start of the French course. They looked at the strength of connections between various areas in the brain and two specific language regions: an area of the brain implicated in verbal fluency, the left anterior insula/frontal operculum (AI/FO), and an area active in reading, the visual word form area (VWFA). The researchers tested the participants’ verbal fluency and reading speed both prior to the course and after its completion. To test verbal fluency, the researchers gave participants a prompt and asked them to speak for two minutes in French. The researchers counted the number of unique words that were used correctly. To test reading speed, the researchers had participants read French passages aloud, and they calculated the number of words read per minute. Participants with stronger connections between the left AI/FO and an important region of the brain’s language network, the left superior temporal gyrus, showed greater improvement in the speaking test. Participants with greater connectivity between the VWFA and a different area of the left superior temporal gyrus language area in the left temporal lobe showed greater improvement in reading speed by the end of the 12-week course. “The most interesting part of this finding is that the connectivity between the different areas was observed before learning,” said a neuroscientist who studies second-language learning and was not involved in the study. “This shows that some individuals may have a particular neuronal activity pattern that may lend itself to better learning of a second language.” To read more about this study, click here.
