Question

Quizplus · Accepted Answer

The concept of conservation is the understanding that changes in the appearance of an object do not necessarily mean changes in the object's quantity. Tammy's belief that the narrow glass contains more soda than the wide glass despite containing the same amount, indicates a lack of conservation. Egocentrism refers to the tendency to view the world solely from one's own perspective and is not relevant in this scenario. Assimilation refers to the process of incorporating new information into pre-existing schemas and is also not relevant here. Object permanence is the understanding that objects continue to exist even when they are no longer visible and is not relevant to the scenario described.
