Not Sure If You Should Take The Leap? Cognitive Benefits of Learning Foreign Languages
We may not look back on our foreign language classes at school with much fondness.However, after reading about the following benefits of learning foreign languages, we may all be searching for our Spanish or French class notes.
Learning a foreign language can be difficult. The older you are, the more challenging it can be. Nevertheless, learning a new language can have a range of cognitive, health and cultural benefits.
Benefits of learning foreign languages: Beneficial for traveling, learning and communicating
Learning a foreign language means you can explore a whole new culture, country, or continent through the native tongue. Learning a foreign language also allows us to communicate with individuals who do not speak our mother tongue.
Benefits of learning foreign languages
Benefits of learning foreign languages: Stay young and stave off disease
Research has found that bilingualism can help counteract cognitive decline. In fact, it was noted that bilingual older adults had better memory than monolingual older adults. Furthermore, there has been links between bilingualism and Alzheimer’s, showing the correlation to speaking more than one language and preventing Alzheimer’s disease. Additionally, Evy Woumans and colleagues have found that in older adults diagnosed with Alzheimer’s disease, the rate of progression is slower in bilingual patients compared to monolingual patients.
Benefits of learning foreign languages: Be more creative
A review into the cognitive correlates of bilingualism, by Olusola Adesope and colleagues found that bilingualism has been associated with enhanced creativity and abstract thinking. Essentially, being proficient in a foreign language can make you more creative and can help you think outside the box.
Benefits of learning foreign languages: Improved problem-solving skills
Bilinguals tend to have better problem-solving skills than monolinguals. In addition, bilinguals tend to perform better on tasks like the Stroop test, which requires an element of conflict management. Being fluent in a foreign language has been linked to enhanced inhibitory control ability. This means that bilinguals are better at ignoring information that interferes with their ability to complete a task. The message here seems to be that learning a foreign language can help us to solve problems faster and help us to ignore irrelevant information.
Benefits of learning foreign languages: Better cognitive control
Researchers Viorica Marion and Anthony Shook tested bilinguals in experiments of task switching. Participants were required to switch between sorting objects based on colour and by shape. Compared to monolinguals, bilinguals displayed high levels of cognitive control. They find it easier to switch between tasks compared to monolinguals. Essentially, learning a foreign language may improve our task switching ability. Researchers propose enhanced cognitive control is due to the ability to balance two languages. Bilingual language processing networks for both languages are active at the same time. As both languages are activated, the individual responds in the correct language by learning to inhibit one language over the other. By doing this, bilinguals improve their inhibitory control mechanism, to the point where when processing language, the process of inhibiting the language that isn’t needed at a particular time becomes second nature.

Benefits of learning foreign languages: Changes brain structure
Bilingualism has been found to increase neuroplasticity. Researcher Rosanna Olsen and colleagues investigated structural brain differences in monolinguals and bilinguals using fMRI. Scans revealed that bilinguals display increased activation in the dorso-lateral prefrontal cortex (DLPFC plays an important role in tasks which require control). This part of the brain is associated with attention and inhibition. The researchers found that the hippocampus and the left superior temporal gyrus are more malleable in bilinguals (The hippocampus is associated with memory and the superior temporal gyrus is associated with sound processing). Furthermore, these structures as well as the frontal lobe are thicker in bilingual individuals (The frontal lobes are associated with executive functions such as problem solving and executive control-need some exercises to improve executive functions?). Increased volumes of white matter have been noted in frontal and temporal lobes. According to researcher Christos Pilatsikas and colleagues, when learning a second language age doesn’t matter, as adults who have learnt a foreign language have shown increase white matter. Being proficient in a foreign language can improve connections of brain regions that control our memory, executive functioning, attention and inhibition processes.

Benefits of learning foreign languages: Improves attention and attention control
Studies have shown that on tasks of attention control, bilinguals tend to perform better than monolinguals. Also bilinguals tend to have a higher attention capacity. Bilinguals are better at filtering out unwanted information and find it easier to focus on more relevant information.
Improves ability to process information– Benefits of learning foreign languages
Being bilingual can benefit sensory and information processing. Jennifer Krizman and colleagues present participants with target sounds embedded in background noise. Compared to monolinguals, bilinguals found it easier to filter out background noise. The researchers found bilingualism enhances sound processing and sustained attention. The study found that bilinguals process sound similarly to musicians. This means that one of the benefits of learning a foreign language is being able to improve the efficiency of the brain’s auditory system, and enhance our ability to distinguish between similar sounds.

Enhances working memory– Benefits of learning foreign languages
Managing two languages puts increased pressure our working memory. To ease the pressure, bilinguals become more efficient at information processing. Combining this with their enhanced inhibitory control ability, a bilingual’s working memory capacity and efficiency us greater than monolinguals.
Learning multiple foreign languages
We have already established that being fluent in a foreign language can improve our information processing abilities and enhance our sustained attention. As a result of these enhanced processes, bilinguals find it easier to learn a third or even fourth foreign language.
Benefits of learning foreign languages
Learning a foreign language can have numerous benefits on our cognitive functions. It improves executive functions, cognitive control, attention, and memory. In addition, neuroimaging studies have revealed that learning a foreign language in later life can actually grow the brain and improve the connections between different brain regions. What is even more interesting is that learning a foreign language can counteract cognitive decline and slow down the progression of Alzheimer’s disease. Regardless of the age at which we learn a foreign language, it is still beneficial for our brains to do so. So, although it may be a little more difficult, it is clearly never too late to reap the benefits of learning foreign languages! Encouraging young children to learn a foreign language may benefit them in later life, so schools should look at making learning a foreign language a compulsory part of the curriculum. Aside from the benefits to cognition and the brain, for all of us who have the travelling bug and want to explore new cultures, learning the lingo is obviously the best place to start!
