Every once in a while nature gives us insight into the human condition by providing us with a unique case whose special properties illuminate the species as a whole. Christopher is such an example. Despite disabilities which mean that everyday tasks are burdensome chores, Christopher is a linguistic wonder who can read, write, speak, understand and translate more than twenty languages. On some tests he shows a severely low IQ, hinting at ineducability, yet his English language ability indicates an IQ in excess of 120 (a level more than sufficient to enter university). Christopher is a savant, someone with an island of startling talent in a sea of inability. This book documents his learning of British Sign Language, casting light on the modularity of cognition, the modality neutrality of the language faculty, the structure of memory, the grammar of signed language and the nature of the human mind.

This is the first detailed explanation of the way British Sign Language works and is the product of many years' experience of research and teaching sign linguistics to deaf and hearing people. It assumes no previous knowledge of linguistics or sign language, and is not structured around traditional headings such as phonology, morphology and syntax. Instead it is set out in such a way as to help learners and their teachers understand the linguistic principles behind the language. There are sections on BSL grammar and also on the use of BSL, including social acceptability in signing, variation, and poetry and humour in BSL. Technical terms and linguistic jargon are kept to a minimum, and the text contains many examples from English, BSL, and other spoken and sign languages. The book is amply illustrated and contains exercises, as well as a reading list for further study.

The discovery of the importance of sign language in the deaf community is very recent indeed. This book provides a study of the communication and culture of deaf people, and particularly of the deaf community in Britain. The authors' principal aim is to inform educators, psychologists, linguists and professionals working with deaf people about the rich language the deaf have developed for themselves - a language of movement and space, of the hands and of the eyes, of abstract communication as well as iconic story telling. The first chapters of the book discuss the history of sign language use, its social aspects and the issues surrounding the language acquisition of deaf children (BSL) follows, and the authors also consider how the signs come into existence, change over time and alter their meanings, and how BSL compares and contrasts with spoken languages and other signed languages. Subsequent chapters examine sign language learning from a psychological perspective and other cognitive issues. The book concludes with a consideration of the applications of sign language research, particularly in the contentious field of education. There is still much to be discovered about sign language and the deaf community, but the authors have succeeded in providing an extensive framework on which other researchers can build, from which professionals can develop a coherent practice for their work with deaf people, and from which hearing parents of deaf children can draw the confidence to understand their children's world.

This is the first textbook dealing specifically with British sign linguistics. It provides essential support for learners of British Sign Language and others interested in the structure and use of BSL, and assumes no previous knowledge of linguistics and sign language. Technical terms and linguistic jargon are kept to a minimum. The book contains over three hundred illustrations and an index of signs and sign phrases. There are also exercises and a reading list for further independent study.
