As I was looking for a limited a list of words I should go for first when learning a new language, I bumped into this interesting paragraph from this blog.
No computer program can change the fact that, for whatever reason, learning a language is hard for adults. Rosetta Stone seeks to emulate a child’s learning, but it’s possible that the brain has changed to make this much harder as an adult. In The Language Instinct, Harvard psycholinguists Steven Pinker guesses this is because learning language was evolutionarily necessary only in childhood. The brain is a metabolic hog that uses a disproportionate share of the calories we consume—it doesn’t make sense to keep around equipment, like the language-learning circuitry, that we won’t need later on.
I find it interesting that evolutionary processes have understood that a kid’s ability to learn how to communicate is vital, thus providing them with an extraordinary but vanishing disposition.
In the same fashion, earlier I was reading extensively about Lactose Intelorance, that post-teenage inability of digesting above a certain quantity of milk. Most studies suggest that you need milk as a baby and that your body can digest very well when young. But just like languages, evolutionary processes also understand that there is no reason you should be drinking milk at age 20, from your mother’s breasts of course as evolution understands… As an obvious consequence, you have a harder time digesting milk when older, because you are not supposed to have any. You’re also having a harder time learning a new language because as evolution seems to understand it, it’s not a natural thing to be speaking more languages that you needed during childhood.
