The Piaget's stages of development is a theory of development that was postulated by Jean Piaget, a cognitive theorist. The theory stated four different stages explaining how a child grows up. each of the stages involves milestones and skills a child develops.
The Piaget's stages of development are:
- The sensorimotor stage (0 - 2 years)
- The preoperational stage (2–7 years)
- The concrete operational stage (7–11 years)
- The formal operational stage (12+ years)
Therefore, the period of cognitive development that follows the concrete operational stage is: the formal operational stage.
