"This book examines spatial language in sign languages (Turkish Sign Language, Croatian Sign Language, American Sign Language, and Austrian Sign Language) and spoken languages (Turkish, English, and Croatian). The book presents a novel model, the Crossmodal Spatial Language, to account for similarities and differences in these languages. The model, which consists of spatial representations, reference frames, temporal representations, conceptual structure, and linguistic representations, shows that the features from spatial input are not necessarily mapped on the spatial descriptions regardless of modality and language." -- book jacket.
