Piaget focuses on which domain of development?

• A. Moral development
• B. Social development
• C. Intellectual development
• D. Physical development

Answer: (C)

Piaget’s work centers on how children's thinking develops—cognitive development. He described how thinking changes qualitatively as children grow, moving through stages where they use different kinds of reasoning—from concrete, perceptual understanding to abstract, hypothetical thought. Key ideas like schemas, assimilation, accommodation, and equilibration explain how kids actively construct and reorganize knowledge in response to new experiences. This emphasis on the processes of thinking and problem solving distinguishes his focus from other domains: moral development concerns judgments of right and wrong, social development concerns interactions and relationships, and physical development concerns growth and motor skills.
