I am aware of immersion methods as well as mnemonics such as the one Daniel Tammet mentioned in Born on a Blue Day. I read that Kim Peek's lack of corpus callosum enabled his brain to absorb information faster with his whole brain but that hindered other daily activities.
My question thus is two-fold:
- Are there any medical conditions which allow one to learn a language faster? For instance, consider John Travolta's character learning Portuguese in a half-an hour car drive.
- What are some current theories in cognitive science that allow one to acquire a language faster? For instance, see the book Babel No More. At the end the author mentions a trick of using the whole body to learn a language as well as the accent.
So, how would an artificial intelligence programmer view language learning? What sort of model would he attempt to create?
