This document discusses two theories of cognitive and moral development:
1. Piaget's Theory of Cognitive Development which describes four stages from birth to adulthood: sensory-motor, preoperational, concrete operational, and formal operational.
2. Kohlberg's Theory of Moral Development which describes three levels of moral reasoning: preconventional (obedience and punishment), conventional (social norms), and postconventional (social contract and universal principles).
The document provides brief explanations of the stages and levels in each theory.
