STUDY OF JEAN PIAGET THEORY (PSYCHOLOGY- B.ED NOTE)
A schema can be defined as a set of linked mental representations of the world, which we use both to understand and to respond to situations. The assumption is that we store these mental representations and apply them when needed.
Whenever they are in a restaurant, they retrieve this schema from memory and apply it to the situation. The schemas Piaget described tend to be simpler than this - especially those used by infants. He described how - as a child gets older - his or her schemas become more numerous and elaborate.
