5 things that happen to your brain when you learn a new language
Never has the bar to entry been so low and the recognized benefits so high.
- Learning a new language has been shown to sharpen your cognitive abilities while helping stave off dementia as you age.
- A University of Chicago study found that businesspeople make better decisions when weighing problems in a non-native tongue.
- Juggling multiple languages lets bilingual speakers switch between tasks with less stress and more control than monolinguists.
In an increasingly globalized world, some believe you only need to speak English in order to engage in international business. As language expert David Crystal explains in his book, How Language Works, this is a false assumption. In Europe, for example, Crystal points out speaking multiple languages is "seen as a criterion of responsible international citizenship."
Crystal writes that multilingualism prepares children to cope with a constantly changing society. Of course, learning a new language isn't confined to the young: there are myriad benefits at every age. We list five important brain-boosting features of learning a foreign language below.
From increased tolerance and employment opportunities to a wide range of memory and problem-solving skills, foreign languages teach us about others as well as ourselves. When you speak in a new language you gain perspective on the reality you've constructed around your original tongue. Not only do you speak differently, you learn how to think differently.
Whether doing it for others or yourself, the many benefits of multilingualism are available through a variety of online courses and apps like Rype or Babbel. Never has the bar to entry been so low and the recognized benefits so high.
1. A boon for cognition
Your muscles become weak when you stop training them. They even atrophy over time. The human brain works in much the same manner. When you stop learning, neural connections are weakened. This results in forgetfulness and potentially dementia.
One of the best means for staving off dementia is learning a new language. As a 2018 review, published in the journal Frontiers in Human Neuroscience, puts it, "One of the non-pharmacological approaches, which may enhance cognitive abilities and protect against the decline in healthy older population, seems to be the learning of a foreign language."
You can grow new neuronal connections at any age provided you keep learning. Foreign languages force you to think differently. A language lesson is like a session in the brain gym. The most effective way to not lose your memory is to keep using it—a necessity when learning a language. Besides memory enhancement, languages improve overall cognitive functioning, raise self-esteem, and increase opportunities for socializing, all necessary skills in aging populations.
2. Improve your decision-making skills
A unique study at the University of Chicago found that businesspeople make better decisions when weighing problems in a non-native tongue. UChicago psychologist Boaz Keysar argues that foreign languages force you to contemplate decisions instead of relying on intuition, which is riddled with biases. As people tend to be loss-averse, they sometimes overlook favorable opportunities. By considering a business opportunity presented in a foreign language, they have to spend more time thinking through all angles of every deal. This reduces the emotional pull of a risky endeavor while revealing potential avenues that have not been considered. This skill makes you a better critical thinker in every language you speak.
3. Creativity unleashed!
An extensive review of the benefits of multilingualism indicate a strong connection between creative flexibility, fluency, and originality. How often have you heard a non-native English speaker make a unique observation with a combination of words you've never heard but that make complete sense? New languages cause you to picture landscapes of possibilities. Choosing the proper term for a feeling or thought is itself an act of creation. During the first few years of life we do this at a rapid pace. As you age, you become more deliberate in your word choice. New languages free you from the conventions of habit. Expressing yourself in a new language is a creative act, and that mindset translates into other realms of life.
4. Increased attention
We live in an attention economy and many people suffer from a deficit. When you hear a word or phrase being spoken, your brain actually guesses at the completed statement. We're constantly guessing reality all the time. Interestingly, bilingual speakers don't turn off one language when listening to another. They're anticipating words from multiple languages all the time, according to an article published in the journal, Cerebrum. As the authors write,
"To maintain the relative balance between two languages, the bilingual brain relies on executive functions, a regulatory system of general cognitive abilities that includes processes such as attention and inhibition."
Because bilingual speakers must navigate two (or more) languages during every conversation, their brain is primed for attention. This results in greater executive control of their cognitive functions, which is a great advantage in the current attention economy.
5. Masters of multitasking
Research from Penn State found bilingual speakers have enhanced cognitive flexibility, which facilitates new learning. This follows a study at the same university that discovered juggling multiple languages affords the speaker greater cognitive control, allowing the speaker to code-switch with ease. This ability to juggle languages lets them switch between tasks with less stress and more control than monolinguists. Instead of bogging the bilingual speaker down when searching for the right language, speaking in multiple tongues actually speeds up their ability to jump from mental task to mental task.

The experience of life flashing before one's eyes has been reported for well over a century, but where's the science behind it?
At the age of 16, when Tony Kofi was an apprentice builder living in Nottingham, he fell from the third story of a building. Time seemed to slow down massively, and he saw a complex series of images flash before his eyes.
As he described it, “In my mind's eye I saw many, many things: children that I hadn't even had yet, friends that I had never seen but are now my friends. The thing that really stuck in my mind was playing an instrument". Then Tony landed on his head and lost consciousness.
When he came to at the hospital, he felt like a different person and didn't want to return to his previous life. Over the following weeks, the images kept flashing back into his mind. He felt that he was “being shown something" and that the images represented his future.
Later, Tony saw a picture of a saxophone and recognized it as the instrument he'd seen himself playing. He used his compensation money from the accident to buy one. Now, Tony Kofi is one of the UK's most successful jazz musicians, having won the BBC Jazz awards twice, in 2005 and 2008.
Though Tony's belief that he saw into his future is uncommon, it's by no means uncommon for people to report witnessing multiple scenes from their past during split-second emergency situations. After all, this is where the phrase “my life flashed before my eyes" comes from.
But what explains this phenomenon? Psychologists have proposed a number of explanations, but I'd argue the key to understanding Tony's experience lies in a different interpretation of time itself.
When life flashes before our eyes
The experience of life flashing before one's eyes has been reported for well over a century. In 1892, a Swiss geologist named Albert Heim fell from a precipice while mountain climbing. In his account of the fall, he wrote is was “as if on a distant stage, my whole past life [was] playing itself out in numerous scenes".
More recently, in July 2005, a young woman called Gill Hicks was sitting near one of the bombs that exploded on the London Underground. In the minutes after the accident, she hovered on the brink of death where, as she describes it: “my life was flashing before my eyes, flickering through every scene, every happy and sad moment, everything I have ever done, said, experienced".
In some cases, people don't see a review of their whole lives, but a series of past experiences and events that have special significance to them.
Explaining life reviews
Perhaps surprisingly, given how common it is, the “life review experience" has been studied very little. A handful of theories have been put forward, but they're understandably tentative and rather vague.
For example, a group of Israeli researchers suggested in 2017 that our life events may exist as a continuum in our minds, and may come to the forefront in extreme conditions of psychological and physiological stress.
Another theory is that, when we're close to death, our memories suddenly “unload" themselves, like the contents of a skip being dumped. This could be related to “cortical disinhibition" – a breaking down of the normal regulatory processes of the brain – in highly stressful or dangerous situations, causing a “cascade" of mental impressions.
But the life review is usually reported as a serene and ordered experience, completely unlike the kind of chaotic cascade of experiences associated with cortical disinhibition. And none of these theories explain how it's possible for such a vast amount of information – in many cases, all the events of a person's life – to manifest themselves in a period of a few seconds, and often far less.
Thinking in 'spatial' time
An alternative explanation is to think of time in a “spatial" sense. Our commonsense view of time is as an arrow that moves from the past through the present towards the future, in which we only have direct access to the present. But modern physics has cast doubt on this simple linear view of time.
Indeed, since Einstein's theory of relativity, some physicists have adopted a “spatial" view of time. They argue we live in a static “block universe" in which time is spread out in a kind of panorama where the past, the present and the future co-exist simultaneously.
The modern physicist Carlo Rovelli – author of the best-selling The Order of Time – also holds the view that linear time doesn't exist as a universal fact. This idea reflects the view of the philosopher Immanuel Kant, who argued that time is not an objectively real phenomenon, but a construct of the human mind.
This could explain why some people are able to review the events of their whole lives in an instant. A good deal of previous research – including my own – has suggested that our normal perception of time is simply a product of our normal state of consciousness.
In many altered states of consciousness, time slows down so dramatically that seconds seem to stretch out into minutes. This is a common feature of emergency situations, as well as states of deep meditation, experiences on psychedelic drugs and when athletes are “in the zone".
The limits of understanding
But what about Tony Kofi's apparent visions of his future? Did he really glimpse scenes from his future life? Did he see himself playing the saxophone because somehow his future as a musician was already established?
There are obviously some mundane interpretations of Tony's experience. Perhaps, for instance, he became a saxophone player simply because he saw himself playing it in his vision. But I don't think it's impossible that Tony did glimpse future events.
If time really does exist in a spatial sense – and if it's true that time is a construct of the human mind – then perhaps in some way future events may already be present, just as past events are still present.
Admittedly, this is very difficult to make sense of. But why should everything make sense to us? As I have suggested in a recent book, there must be some aspects of reality that are beyond our comprehension. After all, we're just animals, with a limited awareness of reality. And perhaps more than any other phenomenon, this is especially true of time.
Might as well face it, you're addicted to love.
- Many writers have commented on the addictive qualities of love. Science agrees.
- The reward system of the brain reacts similarly to both love and drugs
- Someday, it might be possible to treat "love addiction."
Since people started writing, they've written about love. The oldest love poem known dates back to the 21st century BCE. For most of that time, writers also apparently have been of two (or more) minds about it, announcing that love can be painful, impossible to quit, or even addictive — while also mentioning how nice it is.
The idea of love as an addiction is one that is both familiar and unsettling. Surely it can't be the case that our mutual love with our partner — a thing that can produce euphoria, consumes a great deal of our time, and which we fear losing — can be compared to a drug habit? But indeed, many scientists have turned their attention to the idea of "love addiction" and how your brain on drugs might resemble your brain in love.
Love and other drugs
In a 2017 article published in the journal Philosophy, Psychiatry, & Psychology, a team of neuroethicists considered the idea that love is addicting and held the idea up to science for scrutiny.
They point out that the leading model of addiction rests on the notion of a drug causing the brain to release an unnatural level of reward chemicals, such as dopamine, effectively hijacking the brain's reward system. This phenomenon isn't strictly limited to drugs, though they are more effective at this process than other things. Rats can get a similar rush from sugar as from cocaine, and they can have terrible withdrawal symptoms when the sugar crash kicks in.
On the structural level, there is a fair amount of overlap between the parts of the brain that handle love and pair-bonding and the parts that deal with addiction and reward processing. When inside an MRI machine and asked to think about the person they love romantically, the reward centers of people's brains light up like Broadway.
Love as an addiction
These facts lead the authors to consider two ideas, dubbed the "narrow" and "broad" views of love as an addiction.
The narrow view holds that addiction is the result of abnormal brain processes that simply don't exist in non-addicts. Under this paradigm, "food-seeking or love-seeking behaviors are not truly the result of addiction, no matter how addiction-like they may outwardly appear." It could be that abnormal processes cause the brain's reward system to misfire when exposed to love and to react to it excessively.
If this model is accurate, love addiction would be a rare thing — one study puts it around five to ten percent of the population — but could be considered a disorder similar to others and caused by faulty wiring in the brain. As with other addictions, this malfunction of the reward system could lead to an inability to fully live a typical life, difficulty having healthy relationships, and a number of other negative consequences.
The broad view looks at addiction differently, perhaps even radically.
It begins with the idea that addiction exists on a spectrum of motivations. All of our appetites, including those for food and water, exist on this spectrum and activate similar parts of the brain when satisfied. We can have appetites for anything that taps into our reward system, including food, gambling, sex, drugs, and love. For most people most of the time, our appetites are fairly temperate, if recurring. I might be slightly "addicted" to food — I do need some a few times per day — but that "addiction" doesn't have any negative effects on my health.
An appetite for cocaine, however, is rarely temperate and usually dangerous. Likewise, a person's appetite for love could reach addiction levels, and a person could be considered "hooked" on relationships (or on a particular person). This would put love addiction at the extreme end of the spectrum.
None of this is to say that the authors think that love is bad for you just because it can resemble an addiction. Love addiction is not the same as cocaine addiction at the neurological level: important differences, like how long it takes for the desire for another "hit" to occur, do exist. Rather, the authors see this as an opportunity to reconsider our approach to addiction in general and to think about how we can help the heartsick when they just can't seem to get over their last relationship.
Is "love addiction" a treatable disorder?
Hypothetically, a neurological basis for an addiction to love could point toward interventions that "correct" for it. If the narrow view of addiction is accurate, perhaps some people will be able to seek treatment for love addiction in the same way that others seek help to quit smoking. If the broad view of addiction is correct, the treatment of love addiction would be unlikely as it may be difficult to properly identify where the cutoff of acceptability on a spectrum should be.
Either way, since love is generally held in high regard by all cultures and doesn't quite seem to be in the same category as a bad cocaine habit in terms of social undesirability, the authors doubt we'll be treating anyone for "love addiction" anytime soon.
A brief passage from a recent UN report describes what could be the first-known case of an autonomous weapon, powered by artificial intelligence, killing in the battlefield.
- Autonomous weapons have been used in war for decades, but artificial intelligence is ushering in a new category of autonomous weapons.
- These weapons are not only capable of moving autonomously but also identifying and attacking targets on their own without oversight from a human.
- There's currently no clear international restrictions on the use of new autonomous weapons, but some nations are calling for preemptive bans.
Nothing transforms warfare more violently than new weapons technology. In prehistoric times, it was the club, the spear, the bow and arrow, the sword. The 16th century brought rifles. The World Wars of the 20th century introduced machine guns, planes, and atomic bombs.
Now we might be seeing the first stages of the next battlefield revolution: autonomous weapons powered by artificial intelligence.
In March, the United Nations Security Council published an extensive report on the Second Libyan War that describes what could be the first-known case of an AI-powered autonomous weapon killing people in the battlefield.
The incident took place in March 2020, when soldiers with the Government of National Accord (GNA) were battling troops supporting the Libyan National Army of Khalifa Haftar (called Haftar Affiliated Forces, or HAF, in the report). One passage describes how GNA troops may have used an autonomous drone to kill retreating HAF soldiers:
"Logistics convoys and retreating HAF were subsequently hunted down and remotely engaged by the unmanned combat aerial vehicles or the lethal autonomous weapons systems such as the STM Kargu-2... and other loitering munitions. The lethal autonomous weapons systems were programmed to attack targets without requiring data connectivity between the operator and the munition: in effect, a true 'fire, forget and find' capability."
Still, because the GNA forces were also firing surface-to-air missiles at the HAF troops, it's currently difficult to know how many, if any, troops were killed by autonomous drones. It's also unclear whether this incident represents anything new. After all, autonomous weapons have been used in war for decades.
Lethal autonomous weapons
Lethal autonomous weapon systems (LAWS) are weapon systems that can search for and fire upon targets on their own. It's a broad category whose definition is debatable. For example, you could argue that land mines and naval mines, used in battle for centuries, are LAWS, albeit relatively passive and "dumb." Since the 1970s, navies have used active protection systems that identify, track, and shoot down enemy projectiles fired toward ships, if the human controller chooses to pull the trigger.
Then there are drones, an umbrella term that commonly refers to unmanned weapons systems. Introduced in 1991 with unmanned (yet human-controlled) aerial vehicles, drones now represent a broad suite of weapons systems, including unmanned combat aerial vehicles (UCAVs), loitering munitions (commonly called "kamikaze drones"), and unmanned ground vehicles (UGVs), to name a few.
Some unmanned weapons are largely autonomous. The key question to understanding the potential significance of the March 2020 incident is: what exactly was the weapon's level of autonomy? In other words, who made the ultimate decision to kill: human or robot?
The Kargu-2 system
One of the weapons described in the UN report was the Kargu-2 system, which is a type of loitering munitions weapon. This type of unmanned aerial vehicle loiters above potential targets (usually anti-air weapons) and, when it detects radar signals from enemy systems, swoops down and explodes in a kamikaze-style attack.
Kargu-2 is produced by the Turkish defense contractor STM, which says the system can be operated both manually and autonomously using "real-time image processing capabilities and machine learning algorithms" to identify and attack targets on the battlefield.

In other words, STM says its robot can detect targets and autonomously attack them without a human "pulling the trigger." If that's what happened in Libya in March 2020, it'd be the first-known attack of its kind. But the UN report isn't conclusive.
It states that HAF troops suffered "continual harassment from the unmanned combat aerial vehicles and lethal autonomous weapons systems," which were "programmed to attack targets without requiring data connectivity between the operator and the munition: in effect, a true 'fire, forget and find' capability."
What does that last bit mean? Basically, that a human operator might have programmed the drone to conduct the attack and then sent it a few miles away, where it didn't have connectivity to the operator. Without connectivity to the human operator, the robot would have had the final call on whether to attack.

To be sure, it's unclear if anyone died from such an autonomous attack in Libya. In any case, LAWS technology has evolved to the point where such attacks are possible. What's more, STM is developing swarms of drones that could work together to execute autonomous attacks.
Noah Smith, an economics writer, described what these attacks might look like on his Substack:
"Combined with A.I., tiny cheap little battery-powered drones could be a huge game-changer. Imagine releasing a networked swarm of autonomous quadcopters into an urban area held by enemy infantry, each armed with little rocket-propelled fragmentation grenades and equipped with computer vision technology that allowed it to recognize friend from foe."
But could drones accurately discern friend from foe? After all, computer-vision systems like facial recognition don't identify objects and people with perfect accuracy; one study found that very slightly tweaking an image can lead an AI to miscategorize it. Can LAWS be trusted to differentiate between a soldier with a rifle slung over his back and, say, a kid wearing a backpack?
Opposition to LAWS
Unsurprisingly, many humanitarian groups are concerned about introducing a new generation of autonomous weapons to the battlefield. One such group is the Campaign to Stop Killer Robots, whose 2018 survey of roughly 19,000 people across 26 countries found that 61 percent of respondents said they oppose the use of LAWS.
In 2018, the United Nations Convention on Certain Conventional Weapons issued a rather vague set of guidelines aiming to restrict the use of LAWS. One guideline states that "human responsibility must be retained when it comes to decisions on the use of weapons systems." Meanwhile, at least a couple dozen nations have called for preemptive bans on LAWS.
The U.S. and Russia oppose such bans, while China's position is a bit ambiguous. It's impossible to predict how the international community will regulate AI-powered autonomous weapons in the future, but among the world's superpowers, one assumption seems safe: If these weapons provide a clear tactical advantage, they will be used on the battlefield.
