Final answer:
Jean Piaget envisioned cognitive development as a process that unfolds in stages, with the four stages being sensorimotor, preoperational, concrete operational, and formal operational. Children work through these stages until they reach the concrete operational stage, where they can think logically about real events. Schemas, assimilation, and accommodation are key concepts in Piaget's theory of cognitive development.
Step-by-step explanation:
Jean Piaget envisioned cognitive development as a process that unfolds in stages. He proposed a theory of cognitive development that includes four stages: sensorimotor, preoperational, concrete operational, and formal operational. In Piaget's theory, a schema is a mental framework that helps us make sense of the world. Children work through these stages until they reach the concrete operational stage, where they can think logically about real events. Assimilation, the process of incorporating new information into existing schemas, and accommodation, the process of altering schemas based on new information, play important roles in Piaget's theory of cognitive development.
