Immersion Learning & Brain Growth: What Your Brain Looks Like When Speaking a Foreign Language

What happens in our brains when we speak a foreign language?

Do we think in that language?

Do our brains “Google translate” from our native tongue?

Through MRIs and electrophysiology, researchers took a look at the brain to see what visual effects manifest with foreign language learning.

They also analyzed what these effects can tell us about learning a language.

Brain Growth

In an article by Alison Mackey, an MRI study took a look at two groups: young military recruits with a propensity for language and a control group of medical and cognitive science students.

The language groups studied Dari, Arabic, and Russian, while the control group studied other intensive topics but not language.

Taking MRI scans of both the language students and the control group found that certain areas of the brain grew in size for the language group, while those of the control group did not.

Those in the language group who experienced more brain development in the hippocampus of the cerebral cortex (which has a primary role in learning and memory) demonstrated superior language skills to those who experienced more brain development in the motor region of the cerebral cortex (which has a primary role in speaking words).

The ease with which a language student learned, understood, and spoke the language saw a direct correlation with the areas of the brain that grew.

And brain development directly correlated to performance.

Immersion is Key

Another study, noted in an article by Guy Brockless on Bilingua, explored the inner workings of the brain via electrophysiology.

Completed by Professor Kara Morgan-Short at the University of Illinois, the study used an artificial language to identify the differences in the brain’s function when experiencing immersion learning versus rule learning.

Both groups learned the language, but the immersion group learned it via processes similar to native speakers, which is ideal if your goal is native-like fluency.

Morgan-Short said about the study:

“This brain-based research tells us not only that some adults can learn through immersion, like children, but might enable us to match individual adult learners with the optimal learning contexts for them.”

Both studies inform our understanding of how our brains work when learning a second language.

They also indicate that while not all brains work or develop the same during the process, that data can allow language learners to tailor and customize the best methods of language learning for their own personal growth.

Learning a Culture: From Scholastic Learning to Experiential Learning

Over the past few weeks, we’ve spent a lot of time discussing how important learning the language, religion, and history of your host culture is.

This conscious, and often scholastic, learning process requires time, energy, and discipline in ways that may make you feel like you’re back at school.

It can oftentimes be a tough process, requiring many studious hours logged. After all, you’re investing in educating yourself about an entire culture.

But don’t worry, not all cultural learning will require you to dust off the books. Some of it – and some might say the most important part of it – is experiential.

Learning Through Sharing

You are not going to learn the power and emotion of Spanish flamenco watching it on YouTube.

You are not going to learn the colloquial idioms of Portuguese by memorizing by rote.

You are not going to learn how to make Italian pasta by hand without getting your hands dirty (or flour-y).

Learning culture is an experiential process and, without learning by sharing, you’ll be missing out on all the warmth of learning culture.

Cultures are not two-dimensional. They are living and breathing; they must be experienced in-the-round.

Immersion for Integration

“Instead of having 100 rubles, it’s better to have 100 friends.”

That’s what a Russian proverb says.

And foreign friends will be so much more valuable to you than rubles, as they will be able to show you their cultural behaviors, tell you their history, and teach you their traditions better than any book can.

Making friends is an investment in your cultural integration, as it allows immersion learning.

This type of learning involves sharing time and food and language with local friends.

Whether you’re an expatriate living in your host country or an international manager traveling abroad often, local friends will make learning fun rather than book work.

Not only will local friends make you culturally savvy, but they’re likely to expose you to local entertainment and opportunities that you wouldn’t have been privy to on your own.

And, even better, you’ll build life-long relationships in the process.
