Did you know that over 4 billion people around the world speak more than one language? That’s a pretty impressive number! While I currently only speak one language, I’m on a mission to learn Spanish using Duolingo. But more on that later.
Being bilingual, or even learning a new language later in life, isn’t just a cool skill—it’s like having a superpower for your brain. It can boost your mental abilities, slow down brain aging, and even help prevent certain diseases.
Let’s start with a simple exercise. Imagine looking at an image that could either be a rabbit or a duck. Most people can see both, but not at the same time. Your brain has to switch between the two images. This is similar to how bilingual individuals switch between languages. Children who grow up bilingual can switch between these images faster, as their brains are more practiced at switching between languages.
Learning a second language can also enhance your memory. Research shows that bilingual individuals, from children to those in their 80s, often outperform monolinguals in memory tasks. A study on elderly bilinguals aged 60 to 80 found that those who learned a second language later in life had an even greater memory advantage. This highlights that it’s never too late to start learning a new language.
Moreover, bilingualism can slow down the natural memory decline that comes with aging, which is a significant benefit.
Learning another language can also improve your problem-solving skills. For instance, if you look at two rows of arrows and need to determine if the middle arrows are pointing in the same or opposite directions, bilinguals can make this decision faster. Even in old age, bilinguals have quicker reaction times.
Brain scans reveal that the anterior cingulate cortex, which is linked to attention, decision-making, and impulse control, is more efficient in bilinguals. This makes them better at ignoring irrelevant information and focusing on tasks.
Speaking of focus, bilinguals are better at tuning out distractions. If I were to talk to you with background noise, bilinguals would be more adept at ignoring the noise and concentrating on the conversation.
Want to boost your creativity? A study involving 150 participants tested creativity through standard exercises. While monolinguals often excelled in verbal tasks, bilinguals were more creative with nonverbal solutions. This is likely because they view the world from a broader perspective.
Research consistently shows a positive correlation between bilingualism and creativity, regardless of age, race, or gender. Bilinguals excel in both divergent and convergent thinking and demonstrate stronger cognitive flexibility. This creative edge is evident even in fields like mathematics, where bilingualism enhances problem-solving flexibility.
Some worry that teaching children multiple languages might slow their development. However, most research suggests the opposite. While some language milestones might be delayed, children are essentially doing double the work. Learning a second language helps them understand the grammar of their first language better and doesn’t negatively impact their proficiency. Additionally, second language learners often excel in math and grasp mathematical concepts more effectively.
One of the most profound findings is that bilingualism may delay the onset of Alzheimer’s disease, a form of dementia characterized by memory loss and cognitive decline. Studies indicate that Alzheimer’s onset occurs four to five years later in bilingual individuals compared to monolinguals, regardless of sex, lifestyle, education, or occupation.
Even if you don’t develop dementia, your brain naturally slows with age due to atrophy and loss of synaptic connections. Learning a second language can help mitigate this. Some scientists advocate for language learning programs for older adults, as they engage brain regions affected by aging.
This concept is known as cognitive reserve—the idea that throughout our lives, we build a reserve of cognitive abilities. The larger this reserve, the more resilient we are to aging or disease. Bilingual individuals often recover better after a stroke, and learning new things, especially languages, enhances this cognitive reserve.
Learning another language not only connects you with different cultures but also improves your economic prospects and broadens your worldview. It’s a fantastic way to challenge and stimulate your brain, offering lifelong benefits.
If you’re interested in joining me on this language-learning journey, you can find me on Duolingo under the username ASAP Science Mitch. Let’s tackle learning a new language together! I’m eager to hear about your experiences with language learning on Duolingo, so feel free to share your thoughts. Stay tuned for more exciting science insights!
Engage in a language-switching exercise similar to the rabbit-duck image analogy. Choose two languages you are familiar with and practice switching between them by translating sentences back and forth. This will help you understand how bilingualism enhances cognitive flexibility and switching abilities.
Participate in a memory challenge by learning a list of new vocabulary words in a second language. Test yourself after a week to see how many words you remember. This activity will demonstrate the memory benefits of bilingualism and encourage you to expand your vocabulary.
Try solving puzzles or brain teasers in a second language. This could include crosswords, Sudoku, or logic puzzles. By doing this, you’ll experience firsthand how bilingualism can enhance problem-solving skills and improve focus.
Join a workshop where you express creativity through nonverbal means, such as drawing or music, while incorporating elements from different cultures. This will help you explore the link between bilingualism and creativity, as well as cognitive flexibility.
Participate in a cultural immersion event where you practice speaking a second language with native speakers. This will not only improve your language skills but also enhance your understanding of different cultures, highlighting the social and economic benefits of bilingualism.
Sure! Here’s a sanitized version of the transcript:

Over 4 billion people worldwide are bilingual or multilingual, meaning they speak more than one language, which is impressive. I only speak one language, but I am working hard to learn Spanish with Duolingo, who is today’s sponsor. More on them later.
What if I told you that being bilingual or even becoming bilingual at an older age isn’t just impressive but a brain-changing superpower? It could increase your mental abilities, slow the aging of your brain, and potentially even prevent disease.
Let’s start with a simple example. What do you see? Chances are you see a rabbit or a duck. A lot of people can actually see both, but not at the same time. Your brain has to switch back and forth between the two. These are called ambiguous figures, and it turns out that children who grow up bilingual can switch between the figures much faster, likely because their brains are more adept at switching back and forth between languages.
Learning a second language can also improve your memory. Studies on both children and adults into their 80s found that bilinguals almost always outperform monolinguals on working memory tasks, such as remembering more pictures, objects, or numbers. In fact, one study that looked at elderly bilinguals between 60 to 80 years old found that those who learned a second language later in life had an even greater advantage with memory tasks, highlighting that it’s never too late to start.
Even more significant, this same study found that bilingualism can minimize or delay natural memory degradation often caused by aging, which is huge.
Apart from memory, a second language can improve your problem-solving skills. For example, if you look at two rows and tell me if the middle arrows in each row are pointing in the same or opposite directions, bilinguals are able to make this decision and react more quickly.
Even into old age, bilinguals demonstrate much faster reaction times. Brain scans show that the anterior cingulate cortex, associated with attention, decision-making, and impulse control, is more efficient in bilinguals, making them better at suppressing irrelevant information and focusing on a given task.
Speaking of focus, if I start to talk to you while inserting distracting sounds and noises in the background, bilinguals are actually better at tuning out this noise and suppressing irrelevant information.
The benefits of bilingualism only get more impressive, and you can start your journey towards them with today’s sponsor, Duolingo. Self-learning a new language can be daunting, but Duolingo has made the experience feel like a game, helping you make it a routine, which is the number one factor in becoming bilingual. I’ve been using Duolingo to learn Spanish, and I’m currently working through section three, learning how to describe activities.
Duolingo uses research-backed teaching methods that have been tested for decades, preparing you for real conversations with reading, writing, listening, and speaking practice. After 4 to 6 weeks using Duolingo, eight out of ten learners can start a conversation. You can learn five semesters’ worth of language instruction in five sections on Duolingo. The lesson lengths are great because they allow you to learn on the go, anywhere, anytime.
Now, back to the amazing benefits of learning another language. Want to be more creative? One study tested 150 people on their performance in creativity using standard written exercises to evaluate their ability to create solutions to unique problems. While monolinguals typically had an advantage with verbal exercises, bilinguals were more creative with nonverbal solutions, likely because they perceived the world from a wider range of perspectives.
Many studies have found that bilingualism and creativity are positively correlated, regardless of age, race, or gender. Bilinguals are better at both divergent and convergent thinking and show stronger cognitive inhibition and cognitive flexibility. This creative advantage has even been shown in fields such as math, where bilingualism seems to affect flexibility in problem-solving.
If you’ve ever worried that teaching young kids multiple languages can slow them down, most research shows the opposite. While some language milestones may show delay, the child is doing double the work. Learning a second language helps children better understand the grammar of their first language and does not negatively impact their first language proficiency. Second language learners also show advantages in learning math and understanding mathematical concepts.
Perhaps one of the most profound discoveries in recent years is that bilingualism may actually delay the onset of Alzheimer’s disease, a form of dementia that involves memory loss and other cognitive disabilities. Studies have found that Alzheimer’s onset is around four to five years later in bilingual patients compared to monolinguals, regardless of sex, lifestyle, education, or occupation.
Even for those who won’t end up suffering from dementia, you can still expect your brain to slow as you age due to brain atrophy and the loss of synaptic connections. Learning a second language can play an important role in this too. Some scientists are now suggesting we promote language learning programs for older populations because it engages brain networks that overlap with regions negatively affected by aging.
This touches on a concept known as cognitive reserve—the idea that over our lives, we develop a reserve of thinking abilities. The bigger that reserve, the more aging or disease it takes to break down our capacity. In other words, if you build lots of neuronal connections in your brain throughout your life, losing some from aging won’t impact you as severely.
Bilingual people have even been shown to recover better after a stroke. Learning anything new can impact resilience or cognitive reserve, but language learning seems to be particularly special in this regard.
At the end of the day, learning another language connects you with other cultures, improves your economic outcomes, and allows you to see the world from a different perspective. It’s an incredible way to stimulate and challenge your brain with real benefits that will last a lifetime.
