Final answer:
The inability to view an object from another's vantage point is called egocentrism, a concept from Piaget's stages of cognitive development.
Step-by-step explanation:
The quality of not being able to view an object from another's vantage point is called egocentrism. This is a cognitive characteristic found in children during Piaget's preoperational stage of cognitive development. An example of egocentrism in adolescence is when a 15-year-old might overestimate the visibility of a small pimple, mistakenly believing that others must share her perception. As cognitive abilities develop, individuals often engage in reflective thought, which can lead to a reconsideration of previously held contradictory beliefs and the adoption of a more internally coherent belief system.
