The five-year-old's conception of the appearance, reality, and identity of physical objects was investigated. These concepts are not coextensive in the structure of the young child's cognition. Nor are his identity concepts of conservation the cognitive products of his knowledge about appearance and reality. Indeed, his conservation concepts tend to outstrip his judgments about appearance and reality. Moreover, training the child to more correctly distinguish between appearance and reality does not generally affect his conceptions of conservation.
