Document Summary
Piaget revisited: defined specific general stages of development (qualitative, each stage has its own logic and limits on logic, children construct knowledge of the world. Do this transformation in front of the child and they still get it wrong see video: each task transforms one dimensions of the quantity. Preoperational period: child lacks operators of compensation, reversibility and identity, for number task, children focus on the overall length of the row, they ignore the fact that the number of coins remains the same. Compensation a change in one dimension compensates for a change in another; increase in length of row is due to space in between coins. Reversibility changes can be reversed; can make the longer row shorter again. Concert operational period: children acquires operations of compensation, reversibility, and identity, can sort objects on correct dimensions ignoring other features that make them similar. To pass piaget"s task, children must hold in memory the relationships between the lengths of rods.
