Brain Plasticity

If a person’s brain didn’t receive enough stimulation before the age of three, then it would basically lose its functionality as opposed to those who had it. For instance, if a child was secluded for 10 years without any contact of human language, he or she might not be able to acquire a language even being exposed to linguistic training afterward.

However, my speculation is the plasticity of adult brain and its possibility to acquire a second language. Would it be possible for an adult to learn a foreign language like a child? Supposedly, an individual who did obtain the necessary linguistic stimulation and development of neurons for the language skills, he should be able to acquire another language with native-like fluency. The current theory suggest that a person will not be able to learn a second language if he passes the critical period, especially with the issue of accent. If our brain is being able to be manipulated, then there is no reason that one cannot acquire his second language well.

Is it possible we invent a certain device with electrodes to stimulate our brain so as to make a person acquire a foreign language more easily? If so, what kind of areas should we focus on stimulating? What about a person’s psychological factor, determination, and will power? Can we narrow down to a specific frequency in terms of applying the aforementioned factors to influence our brain’s acquisition of new skills? Would playing a positive and encouraging pep message via audio devices during our sleep help to enhance the brain activities? I’m intrigued to conduct such a research and find out whether this method would improve a person’s second language acquisition.
