Identifies key mechanisms through which a child operates with external knowledge in her social context.This study identifies key mechanisms through which a young child operates with external knowledge in her immediate social context. Central to this is the child's capacity to draw on discourse-based understandings which have become evident in prior interaction. In contrast to studies which analyse development under different headings, such as language, emotions and cognition, Tony Wootton links these aspects in his examination of the state of understanding which exists at any given moment in interaction. The result is a distinctive social constructionist approach to children's development.This study identifies key mechanisms through which a young child operates with external knowledge in her immediate social context.
