Philosopher Ludwig Wittgenstein once wrote, “The limits of my language mean the limits of my world.” When we learn a new language, it is said that we have access to more of the world.

However, that isn’t the only advantage of being bilingual, which is being able to speak more than one language.

Research has found that learning two or more languages can greatly enhance our cognitive ability, as bilingualism stimulates mental development not only in children, but even adults.

When we switch between languages, the executive function of our brain – a set of mental skills that include working memory, flexible thinking, and self-control – is enhanced, leading to a more flexible and agile mind.

BILINGUALISM TRAINS THE BRAIN

The bilingual mind works quickly to turn on one language and turn off the other. This mental work of going back-and-forth between two languages enhances cognitive development.

As such, children who are bilingual have mental flexibility, an agility of the mind that allows them to easily adapt to new rules and situations.

When we switch between languages, the executive function of our brain is enhanced, leading to a more flexible and agile mind.

Such flexibility also leads to greater creativity in bilingual children. That’s because children who can think in two languages can see the same situation in more than one way. This capacity for divergent thinking helps them solve complex problems.

Due to regularly having to switch between languages, bilingual children also have a stronger ability to focus and shift their attention between different tasks faster.

Researchers from the National University of Singapore and the Singapore Institute for Clinical Sciences found that hearing a second language helped children process information more quickly. Bilingual children demonstrated greater efficiency in stimulus encoding as well as in improved recognition memory for familiar stimuli as compared to monolinguals.

Infants who are exposed to more than one language show better attentional control than infants who are exposed to only one language. This means that exposure to bilingual environments should be considered a significant factor in the early development of attention in infancy, the researchers say, and could set the stage for lifelong cognitive benefits.

Studies among 16-month-old infants have found that even minimal multilingual exposure at an early age may enhance communication skills. Infants who regularly hear multiple languages have an advantage in understanding a speaker’s intended meaning – suggesting that practice inhibiting the unused language system could facilitate the development of executive function skills more generally.

Researchers have found that learning a first language enhanced and did not hinder the learning of a second language. A study carried out by Singh et al. (2016) showed that bilingual babies were more sensitive to changes in tone, which affects the meaning of a word in Mandarin but not in English. This year-long study involved 72 one-year-old babies and was conducted by psychologists at the National University of Singapore (NUS).

In another experiment, it was also shown that infants who had exposure to a bilingual background may have advantages when learning a third language. Results suggest that bilingual infants’ sustained openness to non-native contrast may facilitate the uptake of words in other foreign languages.

BILINGUALISM EXPANDS ONE'S OPENNESS TO OTHERS

Bilingual children have also been observed to be more socially well adjusted.

Language opens your child’s world to different communities. From early childhood, bilingual children are better able to see things from other people’s perspectives and communicate the viewpoints of another person.

Recent research from the National University of Singapore shows that bilingual children demonstrate fewer racial biases than monolingual children. Bilingualism, therefore unlocks the potential for building social connections.

Bilingual children are better able to see things from other people’s perspectives and communicate the viewpoints of another person.

Bilingualism may appear to be challenging for young children and their parents, but remember that babies are not born monolingual or bilingual. Every child thus has the potential to learn one or more languages, so don’t hesitate to immerse your children in a bilingual environment from birth!
