The child is likely in the Concrete Operational stage of cognitive development, according to Jean Piaget's theory. This stage occurs roughly between the ages of 7 and 11 years and is characterized by the development of logical thought and the understanding of the concept of conservation—the idea that quantity remains the same despite changes in shape or appearance. The child's understanding that the amount of water remains the same despite its appearance in a different shaped container indicates this level of cognitive development.
