right brain – Success Across Cultures

Both sides of the brain contribute to language learning and expression.

Last week, we found that the left side helps produce speech.

So, what does the right side do?

Let’s take a look.

Right Brain Activated

The left side of the brain is considered the language processing hub.

But when someone suffers a stroke or another injury that impacts the language center in the left hemisphere of the brain, something amazing happens: the right hemisphere takes over.

This made scientists curious as to how much each side of the brain is actually responsible for language processing and production.

This is what they found.

Processing Sounds

Studies have shown that the right hemisphere is specifically triggered when differentiating between sounds.

A study by the University of Delaware taught Mandarin Chinese to 24 native English-speaking adults.

Looking at the students’ brain scans during language acquisition, the study found that the right hemisphere of the brain took center stage when focusing on acoustic details while learning Mandarin Chinese.

Being that the right hemisphere of the brain has been largely overlooked in past language research, University of Delaware cognitive neuroscientist Zhenghan Qi believes these findings can help us understand language learning.

While the right side’s role in language diminishes as the student progresses, in the beginning stages, the right is crucial to pronunciation.

Qi explained:

“It turns out that the right hemisphere is very important in processing foreign speech sounds at the beginning of learning…We found that the more active the right hemisphere is, the more sensitive the listener is to acoustic differences in sound. Everyone has different levels of activation, but even if you don’t have that sensitivity to begin with, you can still learn successfully if your brain is plastic enough.”

Qi explained that adults can train themselves to “become more sensitive to foreign speech sounds.”

Another aspect of right-brain involvement in language was uncovered in the study by cognitive neuroscientist Kshipra Gurunandan, analyzed in last week’s post.

The study found that the right hemisphere was most active in reading foreign language, followed by listening.

Researchers there also found greater right hemisphere involvement in adults who’d learned more than one language in early childhood versus monolingual adults.

So, while right-brain learners might think they don’t stand a chance at learning a second language, due to the stronger left-brain involvement, these studies tell a different story.

Are you a right-brain thinker? Or a left-brain thinker?

In other words, are you a creative, innovative type (right-brain)? Or are you logical and analytical (left-brain)?

And which side is a stronger language learner?

Never fear: both sides of the brain assist language learning, according to research.

But to different degrees and in different ways.

Let’s see how.

Left Side Activated

The left hemisphere of the brain stores some 90 percent of our native language.

This is why it’s long been thought that left-brain thinkers may have a better capacity to learn a second language.

The left frontal lobe – specifically Broca’s area – activates the production and articulation of speech.

The left temporal lobe – specifically the Wernicke’s area – influences language comprehension and development.

This does not mean language learning only involves the left side of the brain; both sides work together in the learning and production of language.

Various parts of the brain are activated to degrees, depending on what aspect of language one is learning, whether it’s the lexicon (words), the sounds (phonology), or the syntax (grammar).

Speech

Studies have found that speaking a foreign language largely activates the left side of the brain.

A study by cognitive neuroscientist Kshipra Gurunandan, of the Basque Center on Cognition, Brain, and Language, looked at brain scans from Spanish speakers who were learning English or Basque.

Each group performed language tasks, involving reading, speaking, and listening in their native and foreign languages.

No matter the language level of the speaker, the left hemisphere of the brain was primarily activated during speaking tasks, while reading and listening were variable.

Gurunandan explained:

“In the earliest stages of language learning the native and new languages tended to activate the same hemisphere, while in the more advanced learners they activated different hemispheres. And the switch from the same to the opposite hemispheres was largest in reading, it was slightly smaller in listening and it was non-existent in speaking.”

The researchers believe this left-brain focus during speech specifically is due to the specialized circuits in this hemisphere which control speech production.

The conclusion we draw here is that left-brain learners will have a greater propensity for learning how to speak a second language.

Next week, we’ll discuss where right-brain learners may have an edge.
