Quizplus · Accepted Answer

Rachel's response is indicative of the preoperational stage of cognitive development, according to Jean Piaget. This stage, which typically occurs from ages 2 to 7, is characterized by egocentrism and a lack of understanding of the concept of conservation—the understanding that quantity remains the same despite changes in shape or appearance. Rachel's belief that Edith has more juice because it appears higher in the glass, despite both glasses containing the same amount, highlights this lack of conservation understanding.
