This is a book recommendation for those wanting to learn about second language acquisition.
It is not about learning languages it is about how people learn languages.
Check it by yourself and be surprised on how much it tunes in with AJATT and Kaufman's views.
It is really fun how it debunks old research, specially about grammar based learning and the critical period hypothesis.
The first chapter is about learning vocabulary!
One thing that I found really interesting is that it says that each word generally has about 25 meanings and more than that, these meanings evolve with time.
There are 2 chapters that talk about brain function and have pretty pictures of brain imaging comparing Early Second Language learners and late second language learners with poor or great skills. It seems the brain gets less and less active with the improvement in skill in the language.
The book didn't got to this conclusion, but isn't it maybe the vocabulary solidifying?
