Quizplus · Accepted Answer

George's behavior indicates that he has not yet developed the concept of conservation, which refers to the understanding that an object's properties (such as its quantity) remain the same despite changes in appearance or arrangement. Dumping out the marbles and seeing them scattered may have made it seem like there were more marbles to George, when in fact the quantity had not changed. Object permanence refers to the understanding that objects continue to exist even when they are out of sight, while accommodation and symbols refer to other aspects of cognitive development.
