Tying together almost four decades of neo-Piagetian research, "Cognitive Development" provides a unique critical analysis and a comparison of concepts across neo-Piagetian theories. Like Piaget, neo-Piagetian theorists take a constructivist approach to cognitive development, are broad in scope, and assume that cognitive development is divided into stages with qualitative differences. Unlike Piaget, however, they define the increasing complexity of the stages in accordance with the child"s information processing system, rather than in terms of logical properties. This volume illustrates these characteristics and evidences the exciting possibilities for neo-Piagetian research to build connections both with other theoretical approaches such as dynamic systems and with other fields such as brain science. The opening chapter provides a historical orientation, including a critical distinction between the "logical" and the "dialectical" Piaget. In subsequent chapters the major theories...
