Piaget was a developmental psychologist who studied cognitive development. He believed that children progress through four distinct stages of mental development, moving from concrete thinking in early childhood to more abstract logical thought in adolescence. Piaget's stage theory of cognitive development proposed that children build understanding of the world through experiences interacting with objects and adapting mental schemas.
