A sign language developed by children at a school in Managua, Nicaragua, over the last 35 years and studied by a Barnard team led by Ann Senghas has been in the news recently (Barnard press release, BBC News, New Scientist, NPR audio; also, from five years ago, a long NY Times Magazine story with photos), and a number of people have sent me links (thanks Bonnie, Eve, and whoever I’m forgetting!). The Wikipedia entry has a good summary of events:
Following the 1979 Sandinista revolution, the newly installed Nicaraguan Government had hundreds of deaf students enrolled in two Managua schools. Initially, the education officials adopted “finger spelling,” using simple signs to limn the alphabets of spoken languages. The result was a complete failure, because most students did not even grasp the concept of words, never having been exposed either to spoken or to written language. The children remained linguistically disconnected from their teachers.
Initially, the students could only use crude gestural signs developed within their own families, but once the students were placed together, they began to build on one another’s signs. While the inexperienced teachers found it hard to understand their students, the children had no problem communicating with each other. A new language had begun to bloom. Within just a few generations, a mature language with rules and grammar was born.
