This book is the first of its kind to summarize and discuss the latest findings into how children make evaluations about the truth of what people tell them - when do they trust what people tell them, and when are they skeptical? With an international range of contributors, and two concluding commentaries which integrate the findings within broader perspectives, the book provides a thorough overview of this emerging sub-field. It will be essential reading for researchers, academic teachers and advanced students working in the areas of cognitive and language development, and will also be of great interest to educationists concerned with nursery and primary education.
