From the first moment of life, language development occurs in the context of social activities. This book emphasises how language development interacts with social and cognitive development, and shows how these abilities work together to turn children into sophisticated language users--a process that continues well beyond the early years. Covering the breadth of contemporary research on language development, Brooks and Kempe illustrate the methodological variety and multi-disciplinary character of the field, presenting recent findings with reference to major theoretical discussions. Through their clear and accessible style, readers are given an authentic flavour of the complexities of language development research. With such research advancing at a rapid pace, Language Development uncovers new insights into a variety of areas such as the neurophysiological underpinnings of language, the language processing capabilities of newborns, and the role of genes in regulating this amazing human ability.
