Piaget's Stages of Cognitive Development
Conservation task
This video features three children completing conservation tasks. The first two children are confronted with a classic conservation task concerning liquid volumes. The first child does not understand conservation (the principle that even though the appearance of substances may change, their key properties remain the same) and is likely in the preoperational stage. The second child understands conservation, demonstrating the concrete operational stage. The third child fails to show an understanding of conservation, and thus is likely still in the preoperational stage of cognitive development.
