Cognitive development involves complex processes of thinking, problem solving, understanding, and learning that begin prenatally and continue throughout life. It involves acquiring and using knowledge, skills, and experiences to build mental models called schemas to manage and understand information. Cognitive development is shaped through interaction with one's environment and experiences that are hands-on, language-rich, allow for exploration and practice, and meet children's developmental readiness. Providing varied, stimulating yet unhurried interactions and experiences best supports children's cognitive growth.
