The advent of modern neurobiological methods over the last three decades has provided overwhelming evidence that it is the interaction of genetic factors and the experience of the individual that guides and supports brain development. Brains do not develop normally in the absence of critical genetic signaling, and they do not develop normally in the absence of essential environmental input. The key to understanding the origins and emergence of both the brain and behavior lies in understanding how inherited and environmental factors are engaged in the dynamic and interactive processes that define and direct development of the neurobehavioral system.Neural Plasticity and Cognitive Development focuses on children who suffered focal brain insult (typically stroke) in the pre- or perinatal period which provides a model for exploring the dynamic nature of early brain and cognitive development. In most, though not all, of the cases considered, the injuries affect substantial portions of one cerebral hemisphere, resulting in patterns of neural damage that would compromise cognitive ability in adults. However, longitudinal behavioral studies of this population of children have revealed only mild cognitive deficits, and preliminary data from functional brain imaging studies suggest that alternative patterns of functional organization emerge in the wake of early injury. Neural Plasticity and Cognitive Development posits that the capacity for adaptation is not the result of early insult. Rather, it reflects normal developmental processes which are both dynamic and adaptive operating against a backdrop of serious perturbation of the neural substrate.

This book brings together papers which address a range of issues regarding the nature and structure of sign languages and other gestural systems, and how they exploit the space in which they are conveyed. The chapters focus on five pertinent areas reflecting different, but related research topics: * space in language and gesture, * point of view and referential shift, * morphosyntax of verbs in ASL, * gestural systems and sign language, and * language acquisition and gesture. Sign languages and gestural systems are produced in physical space; they manipulate spatial contrasts for linguistic and communicative purposes. In addition to exploring the different functions of space, researchers discuss similarities and differences between visual-gestural systems -- established sign languages, pidgin sign language (International Sign), "homesign" systems developed by deaf children with no sign language input, novel gesture systems invented by hearing nonsigners, and the gesticulation that accompanies speech. The development of gesture and sign language in children is also examined in both hearing and deaf children, charting the emergence of gesture ("manual babbling"), its use as a prelinguistic communicative device, and its transformation into language-like systems in homesigners. Finally, theoretical linguistic accounts of the structure of sign languages are provided in chapters dealing with the analysis of referential shift, the structure of narrative, the analysis of tense and the structure of the verb phrase in American Sign Language. Taken together, the chapters in this volume present a comprehensive picture of sign language and gesture research from a group of international scholars who investigate a range of communicative systems from formal sign languages to the gesticulation that accompanies speech.

This work shows that professionals can learn a great deal about young children's emerging language and communication skills by consulting the ones who know the children best - their parents or caregivers.
