The benefits of learning more than one language

Dave Barry, Pulitzer Prize winning American author and columnist, stated in 1991 that: “Americans who travel abroad for the first time are often shocked to discover that, despite all the progress that has been made in the last 30 years, many foreign people still speak in foreign languages”.

Behind Mr. Barry’s satire is a common yet hidden thought among many Americans; “Why bother to learn another language when our economy is the drive of the world and English is the most used language in economic and commercial transactions across the globe?.”

It is hard to know the exact number of people in the world who have an ability to speak more than one language, as there are no reliable global studies. But in 2012, a Eurobarometer survey established that just over half of Europeans (54%) are bilingual, and other studies hypothesize that more than half of the world population uses two or more languages every day. The pervasive presence of bilingualism shows that humans can learn two languages without apparent difficulty.

However, in the United States, bilingualism is often associated with low socioeconomic status, as can be appreciated by the fact that legislation referring to bilingual education used to be included in a Federal program for disadvantaged students. But interest in other languages and cultures is emerging. For some people, interested arose after major events that presented immediate and direct threats to the country’s future[1]. For others, the interest arose hand in hand with the increase of globalization where interactions between countries are closer than ever and they are not only limited to trade, but to politics, to social issues, to scientific collaborations, to music, culture, cuisine.

The ability of a citizenry to speak multiple languages provides a comparative advantage in our globalizing world.  This is because learning a new language is not only a means to improving communication, but more importantly it is a way to promote global understanding. In order to keep its global competitiveness, the United States should raise more educated and multilingual children.



In an interconnected and rapidly changing world, many believe that America’s prosperity and economic strength depends on its students mastering a language other than English.  Consequently, the government, both state and federal, are paving the way to get a multilingual workforce which will enhance their competitiveness in the future. One of the most well-known examples is the 1 Million Strong initiative, endorsed by the US and Chinese governments, whose goal is to expand the number of US students studying Mandarin to 1 million by 2020.  Additionally, some states are now investing heavily in dual immersion programs[2] with one major purpose: to increase their multilingual workforce so to attract new businesses to their states. New York is currently developing 40 new language-immersion programs in its school system. Montana, Delaware, Oregon, Washington, California, Texas and Utah are investing heavily in dual immersion programs. In the case of Utah, its Governor, Gary Herbert, set a target in 2010 for the development of 100 programs in intensive dual-language immersion programs serving 25,000 students by 2015. Utah met that goal two years ago, and the brisk pace continues with the launch of additional programs.

It is clear that there is a growing understanding that multilingualism is a key to future success. Last December 14, 2015, the Senate Education Committee favorably reported Senate Bill No. 3279 that establishes the State Seal of Biliteracy, a recognition for high school graduates who have attained a high level of proficiency in speaking, reading, and writing in one or more world languages in addition to English. The purposes of the State seal are to: encourage students to study languages and promote foreign language instruction in public schools; certify attainment of biliteracy; provide employers with a method of identifying people with language skills; provide colleges and universities with a method to recognize and award academic credits to applicants seeking admission; prepare students with 21st century skills; and affirm the value of diversity and honor multiple cultures.

One month later, the New Jersey Governor, Chris Christie, signed the State Seal of Biliteracy into law. New Jersey is now the 14th state to adopt it, and it is under consideration in a half-dozen more states.


In most school systems, foreign language is taken in high school, with many schools requiring one to three years of foreign language in order to graduate. In some school systems, foreign language is also taught during middle school, and recently, many elementary schools have begun teaching foreign languages as well. While this certainly signifies progress, there is much more to be done. According to the scientific community, second language acquisition should start much earlier.

Almost all human beings acquire a language (and sometimes more than one), to the level of native competency, before age 5. That is because we are all born with an innate biological ability for understanding the principles of organization common to all languages. Furthermore, according to research performed at the University of Washington, language has a critical period of learning. Babies and children are linguistic geniuses until they turn 7 where there is a systematic decline. The graph shown below is indisputable by scientists but there is no common explanation of this phenomena.

  1. Better job opportunities

We have to stop thinking that speaking a foreign language is a nice-to-have rather than a must-have asset.

We live in a competitive world where competition for jobs is increasingly fierce. Not only that, the world is more interconnected than ever and therefore, learning languages is crucial. In fact it’s vital. It is no longer an advantage for a job seeker to speak just one non-native language. Rather, it now could be a drawback for a job seeker to only speak one language. Here there are some eye opening facts:

  • At the end of 2013, CNN Money published that the hottest job skill is being fluent in a foreign language.
  • The Department of Labor estimates a 42% increase in jobs for translators and interpreters between 2010 and 2020.
  • According to, employers may pay between 5-20% more than the base rate to hires with language skills
  • America’s $15-billion, high-tech STEM[3] industry depends on languages to reach foreign markets worth $1.5 trillion.

In the public sector, more than one quarter of the “State Department’s language-designated positions” could not be filled with fully qualified personnel in 2012. Similarly, only 28% of language designated positions in the Department of Defense were filled with personnel who met the proficiency level requirements. U.S. Army soldiers can earn up to $1,000 extra per month by demonstrating proficiency in multiple languages

In the private sector, companies targeting global audiences are seeking bilingual employees to broaden their reach. In New Jersey in particular, there is an increasing demand from employers for candidates who speak world languages. In 2014, jobs for bilingual workers represented at least 1 in 5 online job postings at many of New Jersey’s top employers[4].  New Jersey’s key industries (including Finance and Insurance, Health Care and Social Assistance, and Educational Services) accounted for 3,552 online job postings for bilingual candidates in 2014. Finally, from 2010 to 2014, industries that require high levels of service and communication also show increased demand for bilingual job candidates.

In summary, learning a foreign language makes students more marketable, opens the door for higher pay, and prepares them to join the global workforce.

  1. More global understanding

“To have another language is to possess a second soul” – Charlemagne

Thomas Jefferson is probably one of the best examples of a multilingual American. “I read Greek, Latin, French, Italian, Spanish, and English of course, with something of its radix the Anglo-Saxon.” In addition to the languages he lists, there is some evidence that Jefferson was attempting German. The third president of United States knew the importance to learn other languages and cultures for political reasons.

Language learning is not only a means of improved communication, but more importantly it plays a key role in promoting global understanding and respecting cultural differences.  Language exposes students to another culture, sparking curiosity, empathy and understanding. And these qualities prepare students to interact with people of all ethnicities and backgrounds.

Learning a language is a double win. As brilliant translator Michael Hofmann explains well, “to speak a single language is to be enclosed in one cultural possibility – to be preordained to live in the linguistic and cultural cage into which you are born. If you don’t have another language, you are condemned to occupy the same positions, the same phrases all your life,” he wrote. “It’s harder to outwit yourself, harder to doubt yourself in just one language. It’s harder to play.” To acquire another language is to open yourself up to the world and to increase vastly your employability.

  1. Better cognitive abilities

On the classic TV show “I Love Lucy,” Ricky Ricardo was known for switching into rapid-fire Spanish whenever he was upset, despite the fact Lucy had no idea what her Cuban husband was saying. These scenes were comedy gold, but they also provided a relatable portrayal of the linguistic phenomenon of code-switching.

Code-switching requires a great brain effort. It means that the brain has to discriminate selectively one language as you speak the other, when it is known that both languages are active all the time. It requires a great amount of processing functions in our brains.

There is enough experimental evidence to state that children mastering in more than one language face higher brain processing demands that lead to an increase in brain activity. This increase improves their “brain’s executive function”, the system we use for problem solving, planning, flexible switching, focusing, multi-tasking, inhibitory control, etc. This means that children with a high command of a second language improve their ability to adjust to changes in demands or priorities and switch between goals, increase memory and concentration skills, among others.

Metalinguistic ability is also improved though the acquisition of a second language. This ability allows children to see through the meaning of language to its underlying structure. With metalinguistic ability, children can analyze linguistic representations to extract general grammatical rules and state them explicitly, and control attention to different aspects of a sentence or a word such as its form or its meaning. Of the different metalinguistic abilities, phonological awareness has received most attention. Phonological awareness is the ability to recognize and manipulate linguistic sounds separate from their meanings and has been shown to have a significant contribution to children learning to read.

People who speak two languages have also been shown to have more efficient monitoring systems. According to a study performed by the University of Maryland in conjunction with the University of Pennsylvania and Barcelona, monolinguals and bilinguals respond similarly when the brain’s monitoring system is not taxed, but in conditions requiring high monitoring demands, bilinguals were faster. Bilingual people also outperform monolingual people in spatial working memory tasks.

Studies indicates too that early exposure (before the age of 3) to different languages continues to influence neural processing later in life even after the language is no longer used. Another study by Susan E. Carey, Harvard University, shows that better cognitive development is gained as early as in 7 month old bilingual infants.

Studies also indicate a relationship between language study and basic skills development, including listening and reading. Moreover, there is a correlation between years of language study and SAT scores. And not just on the verbal section. On average, students with four years of foreign language study outscored other students by more than 100 points on the verbal and math sections.

  1. Bilingual people are healthier

We all know that taking part in stimulating physical or mental activity can help maintain cognitive function. It turns out that learning a second language has long lasting cognitive benefits even if it is learnt later in life. It promotes the maintenance of white matter[5] integrity and increases the grey matter[6]. In fact, the higher command in a second language, the better for the brain; the effects of long-life bilingualism on neural circuitry have been shown to promote cognitive reserve[7] in elderly people. As a result, elderly bilinguals outperform monolinguals in executive control tasks.

Furthermore, the ability to speak more than one language helps to delay behavioral symptoms associated with neurodegenerative disorders such as dementia. In particular, the estimated age of onset of Alzheimer’s and the age of the first medical appointment related to symptoms associated with dementia are about 4–5 years later in proficient bilinguals than in monolinguals. This is not to say that mastering at a second language protects against the development of neurodegenerative diseases. Rather, the symptoms associated with such diseases may be delayed in people able to speak more than one language because of the presence of greater cognitive reserve caused by the bilingual experience.

A newer study published by the American Heart Association revealed the people who speak two or more languages are twice as likely to have normal cognition after strokes as those who speak only one.



Language competencies are increasingly important. In this time of globalization, language learning is central to politics, economics, history, and most obviously education.

Marty Abbott, the executive director of the American Council on the Teaching of Foreign Languages, says the U.S. is still far behind other developed countries in producing a multilingual workforce, due to “the Anglophone factor and Americans believing that English is good enough to get along.” However, more and more public institutions, including State and Federal Governments, are acting in response to this interconnected and rapidly changing world by investing in dual immersion programs. They know that competition is not local any more, and in order to compete globally, the U.S. needs a globally prepared workforce.  Moreover, it´s not only about economy. America’s language deficit limits the nation’s ability to coordinate with countries on trade, development, disaster relief, global security, and beyond.

Regarding New Jersey, its demand for bilingual talent is on the rise due to the increasing need to communicate with a diverse customer base, and with operations and competitors overseas.

But learning a second language provides far more than professional opportunities. It develops better social and communicative skills and a deeper knowledge of the world.

Furthermore learning a second language is mental exercise. And there is sufficient experimental evidence supporting the notion that bilingualism/learning a second language improves cognitive abilities beyond language processing, especially on those involved in executive control, outperforming monolinguals in a variety of tasks such as problem solving, planning, flexible switching, focusing, multi-tasking, and inhibitory control. This boost in executive control abilities, which affect cognitive development as early as 7 months-old, continues throughout the life span, possibly enhancing cognitive reserve in the elderly delaying the onset of diseases like dementia and helping better recovery from strokes.

Our role as parents, our role as educators

Unfortunately there are not too many studies about bilingualism yet but researchers agree that the strategies for promoting monolingual children’s language development can be applied successfully to bilingual children.  Below are some tips which studies have proven work for developing language. While you may find some of these tips pretty obvious, I hope you can find useful and new information too.

The more exposure to a second (or third) language, the better.

Decades of research with monolingual children and more recent research with multilingual children have found out that the more exposure the child has had to the language, the better. These studies indicate that the amount of exposure to each language predicts a child’s levels of vocabulary and grammatical development in each language.

The earlier a child is exposed to a second language, the better.

Existing research states that the earlier you introduce your child to the language, the better language outcome he will get. We spoke about quantity before, but high quality exposure gives even better results.

Particularly for children under 18 months, children are more favorable to language learning when we use it as a response to the child’s behavior, attention or verbalization.

With 2 and 3 years old, beneficial language experience takes the form of conversations in which parents or fathers ask their children questions and there are numerous conversational exchanges.

In fact, Children who are exposed to high quality input in two languages before the age of 3 years (and continue to be exposed to both languages over time) outperform others who are first exposed after age 3 in reading, phonological awareness, and competence in both languages. Children who hear two languages from infancy start to learn both languages simultaneously, and the course of development in each language looks very much like the trajectory followed by monolingual children.

Content of parent talk

Additionally, it is not just speaking the language that is important; the content of spoken interactions between parents and children is also extremely important to develop language skills.   If the discussion gets a response from the child,the child is learning more. If we speak about something the child is looking at, the child will be more prone to learn because he will be interested. However children will learn fewer words if parents redirect children’s attention and label objects not of their interest.

Diversity of parental speech

The richer and more diverse the parental speech is, the better the children’s vocabulary development will become. The richness of vocabulary, grammatical and lexical structures is associated with children’s vocabulary size, rate of vocabulary growth, and communicative diversity, phonological awareness, listening comprehension and cognitive skills.

Speaking about past experiences

Parents who talk at length with their children regarding past experiences have children with better vocabulary, story comprehension and narrative skills. This is a very good and easy exercise. Ask questions to your children about past events and encourage them to explain who was there, what objects were involved, what happened, how one thing led to another and why people behaved as they did.

Take dictations

One easy way to significantly raise your child’s vocabulary is taking dictations of children’s oral narratives. It is proven to improve the spelling and the reading comprehension too. . Take a tale that your child likes and do a couple of minutes of dictation every day.

Positive tone

Positive tone is also important. Not only because a negative tone discourages the child, but because the grammatical construction itself. Negative language is typically less rich because it is focused on very few specific words. Furthermore, commands don’t invite a conversation. There is a big different between “Where would you like to go?” and “Let’s go”.

Teaching vocabulary in context

Teaching vocabulary in context also enriches and deepens the child’s background knowledge and hence his or her vocabulary.

A mother that speaks about tools, seasons, plants, insects, and seeds while gardening is providing vocabulary in an appropriate context and therefore, helping her child to acquire a better extensive and connected vocabulary and assimilation of concepts. Do you like to have walks? Bring your child and explain to him/her what you see. Even a visit to the supermarket can enrich the children´s vocabulary with the right interaction.

Reading books

Everyone knows that reading is important, but reading books in particular has numerous advantages. It develops oral language, growth of vocabulary and narrative skills, concepts and knowledge, articulation, phonological awareness, and early forms of writing such as scribbles and drawings. Reading books helps parents to use a more diverse vocabulary and invites conversations around the stories and content of the books.

The last report from the National Early Literacy Panel (2008) presents research and recommendations for early childhood educators for promoting foundational literacy skills. The report identifies the types of early literacy intervention that promote children’s early literacy skills. Their findings support the importance of alphabet knowledge, phonological awareness, rapid auto-naming of letters or digits, rapid auto-naming of objects or colors, writing one’s name, and phonological memory as predictive skills for literacy development. An additional five early literacy skills were also identified as potentially important variables, including concepts of print, print knowledge, reading readiness (e.g., alphabet knowledge), oral language skills, and visual processing. Engagement in literacy activities such as book reading promotes all these literacy skills.

The importance of a community

Having a community that reinforces the use of the second language is paramount to the development and the acquisition of second language. Hearing substantial language input from multiple speakers of any given language is more supportive of language development than hearing it from fewer speakers.


The importance of having bilingual programs available:

In the United States, it is a common pattern for toddlers to become increasingly English-dominant in their language skills during the preschool years, while growth in the secondary language decelerates. However, studies have documented that this doesn’t happen when both languages, the majority and the secondary language receive continual support. If you have the opportunity to enroll your child in a bilingual program, do not hesitate to do it. Many people have the wrong assumption that learning a secondary language negatively affects the language acquisition of the primary language, but studies indicate that children in environments where the dual language input is maintained perform at the same level as monolingual children in both languages by the age of 10 years. And researchers point out that bilingual programs have other important advantages too. Access to multilingual programming can assist children in their language and literacy development by facilitating the integration of component skills such as grammatical knowledge or vocabulary knowledge. Furthermore, this development can contribute to the development of parallel skills in a second or third language because children improve their ability to assimilate concepts. Even adults who can speak two languages find it easier to learn a third language because they have trained their brain for acquiring such a skill.

Becoming bilingual – fast facts and tips

I recently bought a short pamphlet from the American Speech Language Hearing Association (ASHA), whose content I like to share with the families that come to my class, because it highlights in a concise way some important facts and tips.

How to become bilngual

Using two languages is like any other skill. To do it well, children need lots of practice, which families can help provide. Without practice, it may be difficult for children to understand or communicate with people in both languages. It can be hard to know how to teach your child to be bilingual. These facts can help:

Fact 1: There are lots of ways to become bilingual

Some people think that there is one best way to teach children to become bilingual. There is no one right way, but there are different ways preferred among the bilingual families:

  • One parent, one language. For example, Mom speaks Spanish and Dad speaks English. This is the system I personally think it works best for our situation, since Dad is not proficient in Spanish, although he tries his best using as many words in Spanish as he can. Anyway, and this unfortunately is not included in this pamphlet, the ideal way from my point of view would be by location. It works better when both parents can speak both languages and they choose the language to speak depending on the location. For example, they speak English outside home and Spanish when they are at home.
  • By time of day. For example, Spanish is spoken in the daytime, and English is spoken at night.
  • By activity. For example, Spanish is spoken at mealtimes, and English is spoken on the playground.

Another way to help a child learn a new language is to use only one language at home and let the child begin to learn the new one when she/he starts school.

ASHA enumerates different resources to help you teach your child two languages:

Books. Read to your child in both languages. Find the books you need at stores, at libraries, and on the Internet. I’m looking for them non stop to prepare the upcoming lessons, and I’m planning to include all my searches in this blog to make your task easier.

Computer programs or mobile apps. There are many interactive programs and apps that can help your child develop language skills. Initially I was reluctant to use apps and the computer at such a short age, but I have found out that a couple of minutes per day has very good results above all to train the ear in the distinction of the Spanish sounds.

Music. Singing is a great way to introduce a second language to your child, and it can be lots of fun!

Television programs and DVDs. Television programs and DVDs are available in many languages. There are different provides of satellite TV, like Dish, with a wide selection of channels from different countries.

Language groups. Children can learn to be bilingual at language camps, bilingual schools or in bilingual education programs. These groups give children the chance to use two languages with other children. I strongly believe this is the most important resource that can help your children to become bilingual. Language is all about communication, so if your children don’t have an environment where they can communicate in the secondary language, they will just not practice it. And as you know, you can easily forget a language if you don’t practice it.

Fact 2. Most children learn to communicate at about the same age and follow typical developmental patterns. This is true for children learning one, two, or more languages. 

Every bilingual child is unique. Developing skills in two languages depends on the quality and amount of experience the child has using both languages. Use languages that you feel comfortable using. Children learn best when they are provided with good models. That’s true, but it’s true too that monolingual parents can raise bilingual children. I will post more about it in the following weeks.

Fact 3. Learning two languages will not confuse your child

From time to time, children may mix grammar rules, or they might use words from both languages in the same sentence. This is a normal part of bilingual language development. I met once a 5 years old child whose father spoke to her in Catalonian and her mother in Spanish. The family lived in Rumania and enrolled her and her brother in the American International School of Bucarest, where her classes were mainly taken in English. Therefore, she was exposed since a very short age to four languages. One day she woke up and she started speaking in a mix of those four languages that nobody was able to understand. Obviously her parents were astonished and extremely worried. However, a couple of days later, she started speaking normal again, being able to answer and speak in each language without mixing all them up.

It is normal too that when a second language is introduced, some children may not talk very much for a while. This “silent period” can sometimes last several months. Again, this is normal.

Speaking more than one language does not cause a language disorder. Also, research shows that, with practice, children with disorders can learn more than one language.

Your child should be:

using words in the more familiar language (1-1.5 years old).

following simple directions (1-2 years old).

putting two or three words together (2-3 years old).

Every kid can speak more than one language. Even children with disabilities like the Down syndrome. The only difference is that he will need extra help from a speech-language-pathologist. If you are worried about your children’s language development, ASHA recommends you to contact a speech-language pathologist. For more information you can contact or visit their website:
