The social sciences offer a variety of theories on how children develop, and various theories and disciplines apply their own vocabularies and conceptualise different aspects of the processes of socialization. This book looks at the theorizing of socialization in sociology, anthropology, psychology, in the life course approach, and as the interplay of genetics and environmental factors. It analyses the dominant perspectives and viewpoints within each discipline and field, and shows how the various theories and disciplines apply their own vocabularies and conceptualise different aspects of the processes of socialization. It argues that socialization does not represent a fixed trajectory into a static social order, and that different disciplines meet the challenges of complex developmental processes and changing environments in different ways. Socialization is a fundamental concept in sociology, but sociology has only to a limited degree sought to produce a coherent understanding of the processes of socialization, which has to encompass the interplay of societal, psychological and genetic factors. This book draws the threads together and, by doing so, offers a general framework for our understanding of the socialization process. At the centre of this process is the child as a subject, in an interplay with the patterns and significant others of the micro environment as well as with the macro-conditions of the modern knowledge based economies.
