Question

As children watched, Dr. Vallance poured the same amount of juice into two identical glasses. Then she poured the juice from one of those glasses into a taller, narrower glass. When asked which glass now has more juice, children in the concrete operational stage, who have acquired the ability of conservation would say that:__________.1. the tall glass has more2. both glasses have same amount3. they don't know4. the tall glass has less

Answer 1

2. both glasses have same amount

Step-by-step explanation:

Concrete operational stage is being explained by a renown French psychologist , Piaget. He explained in his theory that, concrete operational stage is the third stage of cognitive development in children, where they are able to understand ans solve problems in logical fashion, but they are typically not able to think abstractly or hypothetically. This means that, they have logical reasoning concerning real situations but are not being influenced by changes in appearance.

In this case, because the children is in concrete operational stage, they will still say that the two glasses have the same amount of juice, because they are concern with logical reasoning of real situations.

It should be noted that this stage occur in the children in the age range of 6-8 years.

Answer 2

2. both glasses have same amount

Step-by-step 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. Children who have not developed the concept of conservation will tell that the tall glass has more juice (because they focus on the height). However, 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. Thus they will say that both glasses have same amount of juice.
