FEAST aims to become a regular forum to discuss formal approaches to sign language grammar (in particular in the generative tradition), experimental approaches to sign languages, and their interaction. Tentatively, the 2012 "FEAST" should be organized by the University of Goettingen.
The grammars of sign languages are as highly complex as the grammars of spoken languages and share with them many universal features, despite the difference in modality between spoken languages (which use the auditory channel) and sign languages (which use the visual channel).
Yet, sign languages also differ from spoken languages in radical ways: morphological information in sign languages is often conveyed simultaneously by different articulators rather than linearly; moreover, certain aspects of their phonological, syntactic and semantic structures are not commonly found in spoken languages. These differences raise an interesting challenge both for formal linguistic and experimental research frameworks.
