Cognitive psychology significantly shaped Jean Piaget's philosophies by emphasizing the developmental stages of human cognition. Piaget proposed that children progress through distinct stages—sensorimotor, preoperational, concrete operational, and formal operational—highlighting how they construct knowledge through active learning and interaction with their environment. His theories challenged traditional education methods, advocating for teaching strategies that align with developmental readiness. Piaget's work laid a foundation for understanding constructivist learning, influencing educational practices worldwide, as it emphasizes the role of experience and active engagement in cognitive development, reshaping how educators approach teaching and learning.
