Since the end of the sixties, Piagetian general theory with its inherent power of unification has gradually given way to a multitude of more specific models which is in evidence today. In this volume the authors concentrate on three perspectives namely cognitive, perceptuo-motor and neuropsychological development and attempt to coordinate these traditionally separated views. Good illustrations of these theoretical connections can be found in different chapters although the persistent isolation of these three domains still remains. However the authors believe efforts in developmental psychology must continue in the direction of domain interaction, for theoretical concepts as well as methodological tools.
