Noam Chomsky

For years since I started to study English after the age of 10, I've always been frustrated at the lack of improvement in my ability to speak English without a trace of foreign accent and my ability to write without any grammatical errors. It always seemed to me that learning languages is unlike learning anything else. I can logically understand the pronunciation of the a word and the rules of grammar, but for an unknown reason, I always found it hard to incorporate logical knowledge of language into the actual speaking and writing of English. So a question evolved in my mind: Why is it, that even if you study a language for more than 10 years, you will never be able to improve up to the level of the native speakers?

At first I though the answer would be something to the extend of finding a region of the brain that is specialized for the learning of languages and that region is more developed in people other than I, who are good at linguistics. However, it turned out that the answer entails more than specialized regions in the brain. What I found more interesting is that there is much evidence that supports the selectivist theory, found by Noam Chomsky that the ability to learn language is innate. Here innate means that ‘the language template is pre-organized in the neuronal structure of the brain, so that the fact of being an integral part of a given environment selects the borders of each individual neuronal structure without affecting its fine organization, which pre-exists.’ In this paper, I wish to point out evidence that supports this theory of the innateness of language, and to exam how the language template develops. In conclusion, I wish to gain a better understand of my own language learning process in light of these new findings.

One evidence that points to the innateness of language is the accuracy and speed at which humans process language and the accelerating rate at which children acquire language.
The average speaker produces approximately 150 words per minute, each word chosen from somewhere between 20000 and 40000 alternatives, at error rates below .1%. The average child is already well on her way toward that remarkable level of performance by 5 years of age, with a vocabulary of more than 6000 words and productive control over almost every aspect of sound and grammar in her language. Therefore, unlike learning of other things, which depends on the firing of neuron to make connections, the connections for the learning of language already exist before humans are expose to language through their environments, which accounts for the accuracy of processing language and the speed of acquisition of language.

So how does the innateness of language account for my lack of improved proficiency in English? It turned out that language learning has a critical period. During the acquisition of language, the brain goes through clearing unnecessary connections as language development takes place. In other words, the neuronal synaptic connections are not created, or built as we learn language: they pre-exist: unnecessary ones merely decay as language learning takes place. As a result of this cleaning period, the ability to learn language fluently decreases with age. Young children deprived of languages acquire language fully if learning takes place before puberty. If after puberty, they are very inept at language. ‘Among Chinese and Korean children who have immigrated to the United States there is a linear relationship until puberty between the age of arrival and proficiency in English.’

Alas, this is the answer to my question. Because the ability to learn language is innate and it has a critical development period before the puberty age, when I started to study English, perhaps the innate structure in my brain had already begun its regression in acquiring languages. The language template within my brain had been filled with the Hungarian language, it had already gone through most of the cleaning, meaning it had strengthened the neuronal connection needed for the Hungarian language and gotten rid of the ones that is not needed for learning other languages. The quote in the previous chapter about the age of arrival and proficiency in language, support my speculation about the difficulties in attaining language proficiency after a certain age. Because I started just a little bit before pre teenage years, while there is still room to learn another language, the ability to learn language had already begins its stage of decline and therefore, acquisition and proficiency of the English Language does not come easily for me compared to those who might started studying from an earlier year.

Of course knowing that the structures for learning languages pre-exist within our brain is only the first step to understanding how our brain processes languages. While I gained a basic understanding of the innateness of the ability to learn language and how it accounts for, to some degree, my struggles in achieving proficiency of English, there is still a lot to learn about the structures of the language-learning template. From researching the broad topic of brain and language, I also learned about the lateralization and localization of language on the brain. Even though it would take another paper to elaborate on these two topics, writing the this short essay about learning a foreign language is a good start to understand the greater topic of human language.
