Answer:
Conservation
Step-by-step explanation:
Conservation: Given by Jean Piaget in his developmental theory, and is defined as a person's logical thinking ability which helps the person to determine that a particular quantity will remain the same irrespective of the change in the shape, and size of the container. This stage starts from the age of seven and lasts until eleven years of age.
Example: A child gets offended by the fact that he believes that his mother has given more juice to his sister because the child's glass is wider than his sister. Hence, the volume of the juice seems to more in his sister's glass due to the thickness of the glass.
Piaget would say that Alice is demonstrating the knowledge of conservation.
