This is one of a series of four books which form part of the Open University course Child Development. The series provides a detailed and thorough undergraduate-level introduction to the central concepts, theories, current issues and research evidence in developmental psychology. Psychological Development and Early Childhood is a broad and accessible introduction to theory and research, presenting integrated research-based accounts of development in key areas of early childhood, such as perceptual abilities, early relationships, individuality and object knowledge. A focus on modern developmental theories is complemented by detailed consideration of models of developmental processes. A theme that runs through the book is a concern with the ways in which biological, social and cultural influences interact in development. Psychological Development and Early Childhood is a course text for the Open University course ED209.
