Cognitive development: An example of the preoperational child's thinking; if you were to fill a tall beaker with 8 ounces of water this child would think that it was "more" than a short, wide bowl filled with 8 ounces of water. However, concrete operational children can understand the concept of _______ which means that changing one quality (in this example, height or water level) can be compensated for by changes in another quality (width). Conservation Seriation Classification Reversibility
