Mouth actions in sign languages have been controversially discussed but the sociolinguistic factors determining their form and functions remain uncertain. This first empirical analysis of mouth actions in Irish Sign Language focuses on correlations with gender, age, and word class. It contributes to the linguistic description of ISL, research into non-manuals in sign languages, and is relevant for the cross-modal study of word classes.

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...

This book examines sociolinguistic, educational and psycholinguistic factors that shape the path to sign bilingualism in deaf individuals and contributes to a better understanding of the specific characteristics of a type of bilingualism that is neither territorial nor commonly the result of parent-to-child transmission. The evolution of sign bilingualism at the individual level is discussed from a developmental linguistics perspective on the basis of a longitudinal investigation of deaf learners' bilingual acquisition of German sign language (DGS) and German.

Since the recent creation of a large-scale corpus of Italian Sign Language (LIS), a new research branch has been established to study the sociolinguistic variation characterizing this language in various linguistic domains. However, for nominal modification, the role of language-internal variation remains uncertain. This volume represents the first attempt to investigate sign order variability in this domain, examining what shapes the syntactic structure of LIS nominal expressions. In particular, three empirical studies are presented and discussed: the first two are corpus studies...
