Question

The children from the experiment in the passage participate in a separate study using Piaget's water conservation task. They are shown two identical beakers, containing equal amounts of water. The water from one of the containers is poured into a thinner and taller beaker. Which prediction is most likely to be confirmed?

A.All three age groups will state that the water in the taller beaker is greater in quantity.
B.The majority of the 11-year-olds will state that the amount of water in the taller beaker is the same as in the original beaker.
C.The majority of the 9- and 11-year-olds will state that the amount of water in the taller beaker is greater in quantity.
D.The majority of the 7-year-olds will state that the amount of water in the taller beaker is the same as in the original beaker.

Answer 1

The correct option is B: The majority of the 11-year-olds will state that the amount of water in the taller beaker is the same as in the original beaker.

Step-by-step explanation:

This question has to do with cognitive development and we take Piaget's theory into consideration. According to Piaget, the children at the age of 11 must have completed the concrete operations stage, and hence they must have mastered conservation tasks. This mastery would allow them to know that just because they poured water into a taller beaker does not mean that the quantity would change.
