Answer:
2. both glasses have same amount
Explanation:
Jean Piaget was a psychologist who developed a theory of cognitive development according to which we go through different stages of cognitive development (since birth and until adolescence) and our thinking becomes more complex and logical.
The concrete operational stage takes place between the ages of 7 and 11 years of age and in this stage kids develop the ability of conservation which is a logical thinking ability in which a person understands that a certain quantity will remain the same even if it changes of container or form.
In this example, Dr. Vallance pours the same amount of juice into two identical glasses, then she pours the juice from one of those glasses into a taller, narrower glass. <u>Children who have not developed the concept of conservation will tell that the tall glass has more juice (because they focus on the height)</u>. However, <u>children in the concrete operational stage who have acquired the ability of conservation would understand that the amount of juice is the same if it just changes of container.</u> Thus they will say that both glasses have same amount of juice.
