High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! Conservation refers to an ability in logical thinking according to the psychologist Jean Piaget who developed four stages in cognitive development. During the third stage, the Concrete operational stage, the child of age 7-11 masters this ability, to logically determine that a certain quantity will remain the same despite adjustment of the container, shape, or apparent size. Conservation tasks test a child's ability to see that some properties are conserved or invariant after an object undergoes physical transformation. Conservation itself is defined as the ability to keep in mind what stays the same and what changes in an object after it has changed aesthetically. One who can conserve is able to reverse the transformation mentally and understand compensation.
