 At the same time, by reflecting on their own actions, children develop an increasingly sophisticated awareness of the "rules" that govern them in various ways.For example, it is by this route that Piaget explains this child's growing awareness of notions such as "right", "valid", "necessary", "proper", and so on.In other words, it is through the process of objectification, reflection and abstraction that the child constructs the principles on which action is not only effective or correct but also "justified".
