Quizplus · Accepted Answer

Justin's inability to understand conservation is evidenced by his belief that Jay has more gum simply because it appears longer. This inability to understand conservation is a typical developmental milestone for a child his age. Animism, object permanence, and egocentricity are all concepts that develop earlier in a child's development.
