Piagetian Theory, Development of Conceptual Structure

Jean Piaget established an important approach to the study of mental development. He distinguished a series of stages of cognitive development and outlined a process of change through which children actively create a new type of intelligence at each stage. New tools, in contextual and cultural analysis, dynamical systems theory, and neuroscience, are helping to realize his goal of connecting developmental stages with processes of growth.
