When first published in 1923, this classic work took the psychological world by storm. Piaget's views expressed in this book, have continued to influence the world of developmental psychology to this day.

Jean Piaget was one of the most salient and inspirational figures in psychological and educational research of the 20th century. He was also prolific, authoring or editing over 80 books and numerous journals and papers which spawned a continuation of his work over the following decades. His work now compromises a major component of many courses on children's psychological development and in a research tradition which is expanding, scholars may need access to the original texts rather than secondhand accounts. This volume is the sixth of nine reproducing Piaget's original works - they are also available as a boxed set.

This is one of a series of four books that forms part of the Open University course on child development. The series provides a detailed and thorough introduction to the central concepts, theories, issues and research evidence in developmental psychology. Cognitive and Language Development in Children gives an up-to-date and accessible account of how thinking and language develop during childhood. The book is innovative in its approach: it starts by considering cognition and language in infants and continues to weave together these two areas in subsequent chapters that cover aspects of their development through childhood. The chapters have been prepared by leading researchers and theorists in collaboration with members of the Open University course team. Building on the themes in The Foundations of Child Development, a previous book within the series, the editors provide a fully up-to-date, broad and engaging overview of the field, ranging from modern understandings of brain architecture and function to the social and cultural contexts of learning. The chapters have many features to assist and facilitate understanding, including defined learning outcomes, research summaries, activities, readings, definitions of key terms and section summaries.

Jean Piaget was one of the most salient and inspirational figures in psychological and educational research this century. He was prolific, authoring or editing over eighty books and numerous journal papers which have spawned a huge and fertile continuation of his research over the decades. A major component of any course on children's psychological development and a research tradition that is expanding, scholars need access to the original texts rather than relying on secondhand accounts. Piaget wanted to revolutionize the way research methods were conducted. Although he started researching with his colleagues using a traditional method of data collection, he was not fully satisfied with the results and wanted to keep trying to find new ways of researching using a combination of data, which included: naturalistic observation, psychometrics, and the psychiatric clinical examination, in order to have a less guided form of research that would produce more genuine results. As Piaget developed new research methods, he wrote "The Language and Thought of the Child," which aimed to synthesize the methods he was using in order to study the conclusion children drew from situations and how they arrived to such conclusion. The main idea was to observe how children responded and articulated certain situations with their own reasoning, in order to examine their thought processes.

First Published in 1999. Readers will find in this book no direct analysis of child morality as it is practised in home and school life or in children's societies. It is the moral judgment that we propose to investigate, not moral behaviour or sentiments. With this aim in view, a large number of children from the Geneva and Neuchatel schools were questioned and held conversations with them, similar to those we had had before on their conception of the world and of causality. The present volume contains the results of these conversations.
