Gestures are prevalent in communication and tightly linked to language and speech. As such they can shed important light on issues of language development across the lifespan. This volume, originally published as a Special Issue of "Gesture" Volume 8:2 (2008), brings together studies from different disciplines that examine language development in children and adults from varying perspectives. It provides a review of common theoretical and empirical themes, and the contributions address topics such as gesture use in prelinguistic infants, the relationship between gestures and lexical development in typically and atypically developing children and in second language learners, what gestures reveal about discourse, and how all languages that adult second language speakers know can influence each other. The papers exemplify a vibrant new field of study with relevance for multiple disciplines.

Landmark study on the role of gestures in relation to speech and thought.

Over the past few years, scientists and philosophers have discussed the concept of gesture as promising to overcome hyper-intellectualist conceptions of human beings. Its ascendancy reaffirmed the importance of the pragmatic, relational dimension in human experience and cognitive processes. Many questions arise when we focus on the cognitive role of gestures, especially in the new cultural landscape shaped by the digital revolution. Does the idea of gestures highlight the preeminence of bodily experiences? Does it lead to the thinning of the distinction between humans and nonhuman animals? Do gestures help us rethink the allegedly higher human capacities in an antireductionist vein? Do gestures involve reasoning? Are they purely external actions? Do they serve to communicate, or is all communication a form of gesture? What kinds of social relations are involved in the concept of gesture? According to a multidisciplinary orientation, the book inquiries into the possibilities and issues opened up by attending to a philosophy of gestures in philosophy, sociology, psychology, anthropology, and communication studies. Given the current centrality of gestures, the general aim of the book is to reconsider the meaning of "gestures" and try to answer old and new questions.

Many nonverbal behaviors—smiling, blushing, shrugging—reveal our emotions. One nonverbal behavior, gesturing, exposes our thoughts. This book explores how we move our hands when we talk, and what it means when we do so. Susan Goldin-Meadow begins with an intriguing discovery: when explaining their answer to a task, children sometimes communicate different ideas with their hand gestures than with their spoken words. Moreover, children whose gestures do not match their speech are particularly likely to benefit from instruction in that task. Not only do gestures provide insight into the unspoken thoughts of children (one of Goldin-Meadow’s central claims), but gestures reveal a child’s readiness to learn, and even suggest which teaching strategies might be most beneficial. In addition, Goldin-Meadow characterizes gesture when it fulfills the entire function of language (as in the case of Sign Languages of the Deaf), when it is reshaped to suit different cultures (American and Chinese), and even when it occurs in children who are blind from birth. Focusing on what we can discover about speakers—adults and children alike—by watching their hands, this book discloses the active role that gesture plays in conversation and, more fundamentally, in thinking. In general, we are unaware of gesture, which occurs as an undercurrent alongside an acknowledged verbal exchange. In this book, Susan Goldin-Meadow makes clear why we must not ignore the background conversation.

Gestures are now viewed as an integral part of spoken language. But little attention has been paid to the recipients’ cognitive processes of integrating both gesture and speech. How do people understand a speaker’s gestures when inserted into gaps in the flow of speech? What cognitive-semiotic mechanisms allow this integration to occur? And what linguistic and gestural properties do people draw on when construing multimodal meaning? This book offers answers by investigating multimodal utterances in which speech is replaced by gestures. Through fine-grained cognitive-linguistic and cognitive-semiotic analyses of multimodal utterances combined with naturalistic perception experiments, six chapters explore gestures’ potential to realize grammatical notions of nouns and verbs and to integrate with speech by merging into multimodal syntactic constructions. Analyses of speech-replacing gestures and a range of related phenomena compel us to consider gestures as well as spoken and signed language as manifestations of the same conceptual system. An overarching framework is proposed for studying these different modalities together – a multimodal cognitive grammar.

Research on the multifaceted aspects of modeling, analysis, and synthesis of - man gesture is receiving growing interest from both the academic and industrial communities. On one hand, recent scienti?c developments on cognition, on - fect/emotion, on multimodal interfaces, and on multimedia have opened new perspectives on the integration of more sophisticated models of gesture in c- putersystems.Ontheotherhand,theconsolidationofnewtechnologiesenabling “disappearing” computers and (multimodal) interfaces to be integrated into the natural environments of users are making it realistic to consider tackling the complex meaning and subtleties of human gesture in multimedia systems, - abling a deeper, user-centered, enhanced physical participation and experience in the human-machine interaction process. The research programs supported by the European Commission and s- eral national institutions and governments individuated in recent years strategic ?elds strictly concerned with gesture research. For example, the DG Infor- tion Society of the European Commission (www.cordis.lu/ist) supports several initiatives, such as the “Disappearing Computer” and “Presence” EU-IST FET (Future and Emerging Technologies), the IST program “Interfaces & Enhanced Audio-Visual Services” (see for example the project MEGA, Multisensory - pressive Gesture Applications, www.megaproject.org), and the IST strategic - jective “Multimodal Interfaces.” Several EC projects and other funded research are represented in the chapters of this book.
