Watch this video from my favorite podcast, NPR Radio Lab
Can you follow the "words"?
This is a film from Will Hoffman and Daniel Mercadante to accompany Radiolab's Words episode.
Listen to the two audio podcasts that go with this video, discussing the relationship between language and thinking:
Words - " a debate about whether kids can think before they have words"
Voices in your head - " the connection between thought, inner speech, and the voice in our heads."
