The First Signs of Washoe
All normal humans have language: no other living organisms do.
This view is still maintained by many scientists: that one of the essential differences between man and other animals is our unique control of language.
But in 1966, two psychologists began an experiment that challenges this assumption. They took a chimpanzee called Washoe into their own home and brought her up almost as a human child-but using only sign language in her presence. Hoping that she would somehow pick it up, they recorded her progress on film. Their efforts did not go unrewarded. Narrator IAN HOLM
