Offering a unique focus on the development of human communication, this book integrates and synthesizes a more comprehensive array of research than most investigations of communicative development. As such, it incorporates materials dealing with the development of nonverbal communication, language, and cognition, and examines how they are integrated in the growing child's everyday interaction. This information is distilled into a set of key principles and practices - culled from a variety of fields including developmental and social psychology, sociolinguistics, psycholinguistics, and communication - for parents or adults interested in child development. While this book does not offer an in-depth view in any one area, it provides a comprehensive overview of the various components of human communicative development and its significance for the child's cognitive and emotional growth. It is quite clear that developmental processes are constrained by multiple influences whose interactions have just begun to be uncovered. Examining the diverse facets of communicative development will enable professionals to garner further insights into the mystery of human communication.
