Marcy's belief that the broken candy bar has more candy than the unbroken candy bar shows a lack of conservation. Conservation is the understanding that the amount of a substance remains the same even if its shape or arrangement changes. According to Piaget's theory, conservation is a skill that develops during the concrete operational stage of development, which occurs between the ages of 7 and 11. Therefore, Marcy has not yet completed the transition to the concrete operational stage.
