Which theorist is known for proposing four stages of cognitive development in children?

• A. Froebel
• B. Piaget
• C. Vygotsky
• D. Montessori

Answer: (B)

Think about how children's thinking grows through distinct phases. Piaget is the psychologist who described four major stages of cognitive development that children pass through as they learn to think about the world. He laid them out in order: sensorimotor (birth to about 2 years), where babies learn through senses and actions and develop object permanence; preoperational (about ages 2 to 7), where symbolic thinking emerges but logic is limited and egocentrism is common; concrete operational (about ages 7 to 11), where logical thinking about concrete objects and concepts develops and conservation emerges; and formal operational (beginnings around 12 and up), where abstract and hypothetical reasoning becomes possible. These stages reflect qualitative changes in how children think, not just more of the same. Other theorists—Froebel with an emphasis on play, Montessori with a focus on a prepared environment and hands-on materials, and Vygotsky with the importance of social interaction—contribute different ideas, but the framework of four distinct cognitive stages is specifically associated with Piaget.
