Zapping the Brain Improved Language Learning Abilities by 13%

“Humans are excellent perceptual learners,” the paper’s introduction reads. “Yet, a notable and well-documented exception is the acquisition of non-native speech categories in adulthood.”
By stimulating the vagus nerve using the ear pieces, the group was better able to better identify and distinguish between four different Mandarin tones, as
That’s impressive, because differentiating between those four common tones is extremely hard for native English speakers who are not used to tonal languages.
Overall, they saw an improvement of 13 percent in distinguishing an easier-to-tell-apart pair of Mandarin tones when compared to those who didn’t receive brain stimulation — although the effect was almost imperceptible more difficult tones.
“Showing that non-invasive peripheral nerve stimulation can make language learning easier potentially opens the door to improving cognitive performance across a wide range of domains,” Fernando Llanos, a postdoc researcher at the University of Pittsburg’s Sound Brain Lab and lead author on the study, said in
The same effect could be generalized to learning sound patterns of other languages according to the researchers.
“In general, people tend to get discouraged by how hard language learning can be, but if you could give someone 13 percent to 15 percent better results after their first session, maybe they’d be more likely to want to continue,” said Matthew Leonard, an assistant professor of neurological surgery at the University of California, San Francisco and co-author of the study.
The researchers are now investigating if extending the learning sessions with stimulation could enhance the effect for the more-difficult-to-distinguish tones.
Similar brain stimulation of the same area, the vagus nerve, has been used to
However, these treatments tend to be far more invasive when compared to the non-invasive ear pieces used during this particular study.
“We’re showing robust learning effects in a completely non-invasive and safe way, which potentially makes the technology scalable to a broader array of consumer and medical applications, such as rehabilitation after stroke,” senior author Bharath Chandrasekaran, professor and vice chair of research at the University of Pittsburgh School of Health and Rehabilitation Sciences, said in the statement.
