The systems approach in developmental psychology: fundamental concepts and principles

Developmental Psychology seems to have come to an unifying theoretical framework which may make feasible to overcome the fragmentation so frequently referred to within the discipline. This is indicated by the widespread support being given to the systems approach, enriched by dialectic and contextual postulates. In this article, we briefly review the antecedents of this approach and explore its core concepts, indicating their roots and the precise way in which they are applied to developmental analyses today. We also examine the implications of the systems approach for developmental investigation, and its challenges.
