There is a general and extensive literature in the development of representational thought and symbolic processes because of its centrality in human evolution. However, the umbrella of science and its method does not necessarily lead to a coherent conceptual model, or agreements among scholars. These basic differences among various disciplines have led to the creation of new and exciting realms of research. This book considers how representational or symbolic thought develops for children's use in a wide array of these circumstances.
