A collection of essays by leading developmental psychologists in which they focus on issues and questions guiding research in their own particular areas of specialty. The essays discuss developmental psychology's major achievements, and comment on what is now known, the sorts of methods that have been used, and where the field might be heading. An introductory chapter by the volume editor provides an overview of the history of the field and its major themes. Subsequent chapters cover a range of topics from behaviour genetics, through cognitive development, language acquisition, mindreading, social relationships, developmental psychopathology, to issues of epistemology in developmental psychology. Collectively, the chapters represent an assessment of the history and current state of knowledge in the field, and the challenges that lie ahead. The book should be useful reading for any researcher and student in developmental psychology, as well as for those in other fields who seek and up-to-date and accessible overview of this discipline.
