I have always been fascinated by people’s ability to communicate in multiple languages. I imagine this is because I was brought up in a dual culture, where two languages are the norm, not the exception. I love to read in French, speak Spanish and write Mandarin, as each language brings a different feeling depending on what is being communicated. I am interested in how an infant acquires language, and how when we are brought up learning one language, how we are able to learn another. What are some of the underlying cognitive mechanisms that facilitate language?
Throughout history people have been interested in language acquisition, but not until Paul Broca and Carl Wernicke began studying language in the late 1800’s that some theories about where language resides in the brain were explored. They felt that language was in two different areas of the brain called Broca and Wernicke’s areas. Later, research found there are not only specific areas, but that language is distributed throughout different areas of the brain.
In the 1950’s, in order for it to fit their school of thought, behaviorist proposed language is learned through reinforcement. They believed children are reinforced positively for speaking correctly and punished for incorrect language usage. After reading this in our text, my first thought was that the behaviorist must not have had children, because if they had they would know how absurd that theory sounds to a parent. When my son was almost 2, he insulted someone he did not like by calling him a “baggy of meat,” was that learned behavior? No, I am positive we did not teach him that, but it was interesting.
Luckily, Noam Chomsky came to the rescue directly challenging the absurd behaviorist when he published his book called, “Syntactic Structures.” In this book, Chomsky proposed language is coded in our genes and that all language has a similar underlying mechanism. He felt we all have a genetically enhanced ability for grammar structure. This was a fortuitous as it facilitated a way of studying the properties of the mind which helped usher in the age of the cognitive revolution. Chomsky, and I, definitely agree that, “as children learn language, they produce sentences that they have never heard and have never been reinforced.” (Chomsky, 1957)
So, just how do infants acquire language ability? According to Eve Clark from Stanford University, children build on categories they have already distinguished. Then, they are able to map language using broad conceptual representations on a cognitive basis. Also, learning to speak draws their attention to grammar, and they are able to build upon what they know. Their ability to conceptualize information is later replaced by linguistic abilities. For a child, language begins with perceptual and auditory input which is a bottom up process, and then they output language by talking which turns it into a top down process.
