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:
