The relationship of language to cognition, especially in development, is an issue that has occupied philosophers, psychologists, and linguists for centuries. In recent years, the scientific study of sign languages and deaf individuals has greatly enhanced our understanding of deafness, language, and cognition. This Counterpoints volume considers the extent to which the use of sign language might affect the course and character of cognitive development, and presents a variety of viewpoints in this debate.
This volume brings the language-thought discussion into a clearer focus, both theoretically and practically, by placing it in the context of children growing up deaf and the influences of having sign language as their primary form of communication. The discussion is also sharpened by having internationally recognized contributors, such as Patricia Siple, Diane Lillo-Martin, and Ruth Campbell, with specialties in varied areas, all converging on a common interest in which each has conducted empirical research. These contributors clarify and challenge the theoretical assumptions that have driven arguments in the language-thought debate for centuries. An introduction by the editors provides a historical overview of the issues as well as a review of empirical findings that have been offered in response to questions about language-thought relations in deaf children. The final chapters are structured in the form of "live" debate, in which each contributor is given the opportunity to respond to the other perspectives presented in this volume.

Sign Languages: Structures and Contexts provides a succinct summary of major findings in the linguistic study of natural sign languages. Focusing on American Sign Language (ASL), this book: offers a comprehensive introduction to the basic grammatical components of phonology, morphology, and syntax with examples and illustrations; demonstrates how sign languages are acquired by Deaf children with varying degrees of input during early development, including no input where children create a language of their own; discusses the contexts of sign languages, including how different varieties are formed and used, attitudes towards sign languages, and how language planning affects language use; is accompanied by e-resources, which host links to video clips. Offering an engaging and accessible introduction to sign languages, this book is essential reading for students studying this topic for the first time with little or no background in linguistics.

Sign languages are of great interest to linguists, because while they are the product of the same brain, their physical transmission differs greatly from that of spoken languages. In this 2006 study, Wendy Sandler and Diane Lillo-Martin compare sign languages with spoken languages, in order to seek the universal properties they share. Drawing on general linguistic theory, they describe and analyze sign language structure, showing linguistic universals in the phonology, morphology, and syntax of sign language, while also revealing non-universal aspects of its structure that must be attributed to its physical transmission system. No prior background in sign language linguistics is assumed, and numerous pictures are provided to make descriptions of signs and facial expressions accessible to readers. Engaging and informative, Sign Language and Linguistic Universals will be invaluable to linguists, psychologists, and all those interested in sign languages, linguistic theory and the universal properties of human languages.
