Be able to recognize examples (and errors that children make) of object permanence, animism, egocentrism and conservation and know what Piagetian stage they occur in
Object permanence: the act of remembering an object... with babies before they achieve object permanence, out of sight, out of mind... when a baby doesn't see the object, they forget about it
Anaimism: they believe objects have intentions... such as believing a wall wanted to hurt them.
egocentrism: they believe that everyone can see, hear, and think like them
conservation: water in one cup, is the same volume as water in another cup
