"This book focuses on American Sign Language to examine the grammatical and conceptual significance of these signs. It guides the reader through the various types of directional signs, the types of spatial representations signs are directed toward, how such spatial conceptions can be represented in mental space theory, and the conceptual purposes served by these signs. The book explains how the pointing behavior of signs accomplishes functions that must be accomplished by any language, spoken or signed. It demonstrates a remarkable integration of grammar and gesture in the service of constructing meaning. These results also suggest that our concept of "language" has been much too narrow and that a more comprehensive look at vocally produced languages will reveal the same integration of gestural, gradient, and symbolic elements."--Jacket.
