Organized bodies of knowledge that we build up about particular objects, situations or phenomena are termed as

Organized bodies of knowledge built about particular objects, situations or phenomena are called schemas or mental schemata.

A schema is a mental framework that groups related information and guides how new experience is understood.

Memory is the broader capacity to store and retrieve information, not the organized structure itself.

Cognition names all mental processes of knowing, of which schemas are only one product.

Metacognition is awareness and control of one's own thinking, a level above simple schemas.

Piaget used schema centrally, and Bartlett's schema theory showed how such structures reshape what we remember.
