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.

A critical exposition of Piaget's views on child language and thought.

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.

Since it was introduced to the English-speaking world in 1962, Lev Vygotsky's highly original exploration of human mental development has become recognized as a classic foundational work of cognitive science. Vygotsky analyzes the relationship between words and consciousness, arguing that speech is social in its origins and that only as children develop does it become internalized verbal thought. Now Alex Kozulin has created a new edition of the original MIT Press translation by Eugenia Hanfmann and Gertrude Vakar that restores the work's complete text and adds materials that will help readers better understand Vygotsky's meaning and intentions. Kozulin has also contributed an introductory essay that offers new insight into the author's life, intellectual milieu, and research methods. Lev S. Vygotsky (1896-1934) studied at Moscow University and acquired in his brief lifespan a nearly encyclopedic knowledge of the social sciences, psychology, philosophy, linguistics, literature, and the arts. He began his systematic work in psychology at the age of 28, and within a few years formulated his theory of the development of specifically human higher mental functions. He died of tuberculosis ten years later, and Thought and Languagewas published posthumously in 1934. Alex Kozulin studied at the Moscow Institute of Medicine and the Moscow Institute of Psychology, where he began his investigation of Vygotsky and the history of Soviet psychology. He emigrated in 1979 and is now Associate Professor of Psychiatry (Psychology) at Boston University. He is the author of Psychology in Utopia: Toward a Social History of Soviet Psychology(MIT Press 1984).
