What would happen if a human being was born with all faculties intact except for the language acquisition capacity?
What would happen if a human being was born with all faculties intact except for the language acquisition capacity? Assuming that the brain did not make up for the deficiency, as it usually does, is it true that: 1) the person can only learn language from observation. If so, can language be learned from observation only? 2) Such a human would more likely be considered deficient in cognition or intelligence, not a speech problem. If this is true, why?
Thanks.
