Final answer:
Piaget's cognitive stages of development are the sensory-motor stage, preoperational stage, concrete operational stage, and formal operational stage.
Step-by-step explanation:
Piaget's theory of cognitive development consists of four stages:
- Sensory-Motor Stage: This stage occurs from birth to approximately 2 years old. During this stage, children learn about the world through their senses and motor behavior.
- Preoperational Stage: This stage occurs from approximately 2 to 7 years old. Children in this stage use symbols to represent words, images, and ideas, but they cannot understand adult logic or mentally manipulate information.
- Concrete Operational Stage: This stage occurs from approximately 7 to 11 years old. Children in this stage can think logically about real events, understand transformations, and grasp the concept of conservation.
- Formal Operational Stage: This stage occurs from age 11 to adulthood. Children in this stage can think abstractly, use hypothetical reasoning, and engage in problem-solving.
