4 STAGES OF COGNITIVE DEVELOPMENT

Cognition refers to thinking and memory processes, and cognitive development refers to long-term changes in these processes.

One of the most widely known perspectives about cognitive development is the cognitive stage theory of a swiss psychologist named Jean Piaget.

Piaget proposed that cognition developed through distinct stages from birth through the end of adolescence:
