Imagine a village where everyone 'speaks'0 sign language. Just such a village - an isolated Bedouin community in Israel with an unusually high rate of deafness - is at the heart of 'Talking Hands - What Sign Language Reveals About the Mind'. There, an indigenous sign language has sprung up, used by deaf and hearing villagers alike. It is a language no outsider has been able to decode, until now. 'Talking Hands' offers an introduction to the signed languages of the world - languages as emphatically human as any other - explaining why they are now furnishing cognitive scientists with long-sought keys to understanding how language works in the mind.
