Over the past decades, the field of sign language linguistics has expanded considerably. Recent research on sign languages includes a wide range of subdomains such as reference grammars, theoretical linguistics, psycho- and neurolinguistics, sociolinguistics, and applied studies on sign languages and Deaf communities. The SLDC series is concerned with the study of sign languages in a comprehensive way, covering various theoretical, experimental, and applied dimensions of sign language research and their relationship to Deaf communities around the world. The series provides a multidisciplinary platform for innovative and outstanding research in sign language linguistics and aims at linking the study of sign languages to current trends in modern linguistics, such as new experimental and theoretical investigations, the importance of language endangerment, the impact of technological developments on data collection and Deaf education, and the broadening geographical scope of typological sign language studies, especially in terms of research on non-Western sign languages and Deaf communities.

The recent recognition of sign languages as legitimate human languages has opened up new and unique ways for both theoretical and applied psycholinguistics and language acquisition have begun to demonstrate the universality of language acquisition, comprehension, and production processes across a wide variety of modes of communication. As a result, many language practitioners, teachers, and clinicians have begun to examine the role of sign language in the education of the deaf as well as in language intervention for atypical, language-delayed populations. This collection, edited by Patricia Siple and Susan D. Fischer, brings together theoretically important contributions from both basic research and applied settings. The studies include native sign language acquisition; acquisition and processing of sign language through a single mode under widely varying conditions; acquisition and processing of bimodal (speech and sign) input; and the use of sign language with atypical, autistic, and mentally retarded groups. All the chapters in this collection of state-of-the-art research address one or more issues related to universality of language processes, language plasticity, and the relative contributions of biology and input to language acquisition and use.

This is the second volume in the series 'Trends in language acquisition research'. The unusual combination in one volume of reports on various different sign languages in acquisition makes this book quite unique.

Only recently has linguistic research recognized sign languages as legitimate human languages with properties analogous to those cataloged for French or Navajo, for example. There are many different sign languages, which can be analyzed on a variety of levels—phonetics, phonology, morphology, syntax, and semantics—in the same way as spoken languages. Yet the recognition that not all of the principles established for spoken languages hold for sign languages has made sign languages a crucial testing ground for linguistic theory. Edited by Susan Fischer and Patricia Siple, this collection is divided into four sections, reflecting the traditional core areas of phonology, morphology, syntax, and semantics. Although most of the contributions consider American Sign Language (ASL), five treat sign languages unrelated to ASL, offering valuable perspectives on sign universals. Since some of these languages or systems are only recently established, they provide a window onto the evolution and growth of sign languages.

This book defines the notion of applied sign linguistics by drawing on data from projects that have explored sign language in action in various domains. The book gives professionals working with sign languages, signed language teachers and students, research students and their supervisors, authoritative access to current ideas and practice.

How children acquire a sign language and the stages of sign language development are extremely important topics in sign linguistics and deaf education, with studies in this field enabling assessment of an individual child’s communicative skills in comparison to others. In order to do research in this area it is important to use the right methodological tools. The contributions to this volume address issues covering the basics of doing sign acquisition research, the use of assessment tools, problems of transcription, analyzing narratives and carrying out interaction studies. It serves as an ideal reference source for any researcher or student of sign languages who is planning to do such work. This volume was originally published as a Special Issue of Sign Language & Linguistics 8:1/2 (2005)

This book focuses on how sign language ideologies influence, manifest in, and are challenged by communicative practices. Sign languages are minority languages using the visual-gestural and tactile modalities, whose affordances are very different from those of spoken languages using the auditory-oral modality.

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 pioneering and original 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.

Recent research on the syntax of signed language has revealed that, apart from some modality-specific differences, signed languages are organized according to the same underlying principles as spoken languages. This book addresses the organization and distribution of functional categories in American Sign Language (ASL), focusing on tense, agreement and wh-constructions.
