Instead, I will briefly review the theory's scope, comprehensiveness, parsimony, applicability, heuristic value and methodological underpinning. I will then evaluate in more detail the theory's utility in describing and explaining cognitive development.

The theory itself is wide-scoped (universal), comprehensive (covering a broad spectrum of cognitive achievement) and elegantly coherent (from neonate to adult).

Inevitably, such an ambitious theory has generated a wealth of research, some supporting, some supplementing, some extending and some disputing aspects of Piaget's theory.

Some of the weaker aspects of Piaget's theory appear to arise from his
