Proponents of the innateness hypothesis (a.k.a linguistic nativism) argue that language is acquired because, as Chomsky contended, humans are born equipped with what he called language acquisition device (LAD). LAD is an inherent biological mechanism that enables us to easily acquire and produce language. One strong evidence in favour of innateness hypothesis is the fact that we can understand and produce sentences and utterances we have never heard.
On the other hand, there is the empiricist camp (linguistic empiricism) which views language as a product of learning. To them all forms of knowledge is learned through senses and that “language and grammar are only learned through exposure and accumulated experience. This is also called the "nurture" perspective as opposed to the "nature" perspective (linguistic nativism).” Check out this Wikipedia page for a detailed discussion of these two hypotheses.
Regardless of which hypothesis provides a valid account of the acquisition vs learning problematic, one solid fact remains indisputable: language or more precisely linguistic performance, parole in de Saussure’s terminology, is an exclusive human feat. It is a source of fascination and wonder, a theme which I want to highlight in today’s post through a curated list of wonderful TED Ed talks.
These are educational video lessons that tackle a wide variety of interesting topics related to language learning, from contentious issues in language philosophy to issues related to the syntactic and semantic mechanics of language learning. You can use these talks with your students in class to engage them in discussions about language.
