What Happens When a Child Grows Up With Zero Language

Right now, your brain is narrating your life in words — but that voice wasn't always there. It had to be built, inside a window of time you'll never remember, and if no one had spoken to you in time, it might never have switched on at all. This video uncovers what happens when a human grows up with no language at all — not a foreign language, not sign language, none. From the Wild Boy of Aveyron to a girl found in a Los Angeles back bedroom in 1970, you'll see what science discovered about the closing biological window for language, why grammar can lock shut even when vocabulary still comes easily, and what any of it has to do with the inner voice running through your own head right now.
