Piaget Conservation Task is a procedure that is used to test the theory that children between the ages of 3-5 thinking ability is limited by what is known as centration. Centration is the tendency to focus on a single, perceptually striking feature of an object or event. This test is not to trick the child, but to merely show that there thinking ability at this age literally doesn't process the fact that even though the glass is taller, it is also skinnier. These children can only focus on that one aspect even though they just watched everything that happened. In this video they also have an example of an older child doing the task to show that she has indeed over come the lack of knowledge of conservation. FACINATING! Watch and see for yourself.

Wow, that is interesting. I was especially surprised by the last test they did in the video with the graham crackers. I don't know any five year olds, but if I did I would certainly test it out on them. Thanks for posting!
