Those of us who try to learn our first foreign language as adults are at a huge disadvantage. I’m not just talking about the common knowledge that languages are harder for adults to learn than children. (This is news to no one.) I’m talking about actual scientific evidence that monolingual brains simply aren’t wired for it.
It turns out that even high school is too late for monolinguals to start learning a language. (News to approximately zero high school students and teachers.) Middle school too. Experts are now saying preschool or kindergarten – before age 7 – is the last best opportunity to learn a second language. By that age the “electrical language pathways” in the brain have solidified, after which it starts becoming difficult to make new ones.
Seven-year-olds have hardly mastered their first language, so how can we be talking about a second one already? Well, this isn’t vocabulary or correctness or even intelligence we’re talking about; it’s the simple ability to differentiate among sounds. This is where adults have a hard time: with their ears being able to hear sounds that don’t exist in their native language, and with their tongues being able to reproduce those sounds. (A 7-year-old can also understand intuitively that “the boy runs” while “the boys run” without stressing over this seemingly random rule of grammar.)
Our brain circuitry for language is established way earlier than that, actually. It goes back to infancy. The brain of a 6-month-old baby can recognize all the sounds that make up all the languages in the world, and will respond equally to them, but shortly after this age they begin selecting only the ones they hear most frequently. Their brains begin “pruning” the neural connections no longer needed. By 10 months of age, babies who have not yet been exposed to a foreign language will simply filter it out when hearing one for the first time. Their brains treat the foreign sounds as “noise” and don’t respond to them. This selective hearing process and pathway pruning continues until the ripe old age of – you guessed it – seven.
Babies exposed to two or more languages from the beginning, however, treat them as equally important inputs. When they hear any of these sounds their brains light up, synapses firing. Those neural pathways are preserved. For life, maybe. There’s evidence indicating that even if a second language lies dormant for many years, it can be revived in adulthood rather easily. There’s also evidence pointing to the rapid ability to learn a third, fourth, fifth language for people who are already bilingual.
Alas, I must have been one of those babies surrounded exclusively by English. Which makes sense, being born in Kansas and all. Trying to learn French now is like doing constant battle with my brain, prodding it to stay alert, forcing it to pay attention when all it wants to do is tune out, relax, and wait for someone to come along and translate for me anything that must be important. In fact if I don’t work diligently I find that it’s trying to imagine English words, no matter how ridiculous, out of certain French sounds. Like hearing a syllable that sounds like “pie” and picturing one in my head, even though I know we’re not talking about pie. (A silly example, and one that I think I’ve finally outgrown, but you get my point.)
Each time I sit down for a focused French lesson, I find that my poor little monolingual brain gets pooped pretty easily. Like after 20 minutes I need a break. I’ve also found myself extremely hungry during these study sessions… thinking this hard is apparently a good calorie burn! Disadvantaged brains must require a lot of fuel. Maybe that’s why I’m picturing a pie.
Why the heck am I writing this, anyway… am I trying to discourage someone from trying to learn a second language as an adult?? No. Lots of people with badly wired brains have overcome this disadvantage and reached fluency, albeit with lots of hard work. Many more have become functional (albeit with lots of errors) relatively quickly. It can be done, but I suspect it’s easier if you have realistic expectations going into it. That’s why I think I failed miserably at my first attempt, Spanish. I thought it would have been easy, and was incredibly dismayed when I found that it wasn’t. Today I still struggle with my immature expectations to speak French perfectly… which is impossible and keeps me from speaking at all. Counterproductive.
I took an informal poll around here, at the base camp of an American mining company in French-speaking Congo. The vast majority of expats show up here with the best intentions to learn French… and then give up pretty quickly. Not having enough time to put into it is one thing, and completely understandable, especially if there isn’t a pressing motivation to keep going. (Most business here, especially at the higher levels, is conducted in English.) But most expats informally polled say they would have liked to learn French but they found it too hard, too strange to their American ears. They called it off.
I think most of us assume that some people are gifted at foreign languages while others are not, just like some people are good at math while others are good at art. (Certainly the people exposed to foreign sounds as an infant or who already speak a second language are more “gifted” than the rest of us, but forget them — they’re in a completely different category.) If we’ve never tried a foreign language before, we have no idea if we’re going to be in the “gifted” category or not. So as soon as we start our first lessons we’re on high alert to figure this out before any further unnecessary humiliation. If we feel we’re struggling too much, which is inevitable, then we’re likely to give up.
But our assumption that we must not be gifted is false. When pretty much anyone first learns to play the clarinet, they make only horrible squeaks for the first six months.
So that’s why I’m writing this. Not to demotivate anyone; just the opposite. When you find that your chosen second language is hard to learn, remember that it’s supposed to be. If you can see that it’s not your age, talent, nor self-perceived “lack” of intelligence, but rather just the way your brain is wired along with billions of others, you can more easily knock down what I think is the first barrier to language learning, and that is not having enough patience with yourself.
Squeak away, future clarinet maestros!
