2 THE ORIGIN AND EVOLUTION OF HUMAN COMMUNICATION If we were walking the walk, were we talking the talk?

3 If we want to understand human communication, therefore, we cannot begin with language. --(Tomasello, p.59, 2008)

15 REFERENTIAL AND INTENTIONAL GESTURE IN CHIMPANZEES Referential pointing and individual intentionality: arm raise = acquire object Referential pointing (referential) and pantomime (iconic gesturing)in Bonobos

16 WHAT WERE THE FUNDAMENTAL BUILDING BLOCKS OF HUMAN COOPERATIVE COMMUNICATION?

17 SHARED INTENTIONALITY Joint intention Joint attention Establishing a common ground (shared understanding of the situation at hand)

18 I KNOW THAT YOU KNOW THAT I KNOW

19 AN ESSENTIAL BUILDING BLOCK Recursive mind-reading
