Can you remember what it was like for you to learn your native language? Probably not, but why is that? As humans, we begin learning to speak our native language during the earliest stages of our lives, in infancy. Most people don’t have many accessible memories from this period of development.

On this week’s episode of Two Guys on Your Head , Art Markman and Bob Duke explore how we learn language.
