Study on Piaget's Theory - Stages of Development

This study done shows a childs lack of Conservation, or the lack of change. That at this certain age of a person's life, they lack the skills to be able to understand the difference between quantitys as shown in the video. For instance, in the video they show that the child believes that they have the same amount of graham crackers because they both have two pieces, although the experimenter, to us, obviously as more than the child. Or when the amount of quarters in each row is the same, but appear unequal to a child because one row is more spaced out than the other.
I find this study very interesting, as it seems like such a simple concept to understand, as it is something very easy for older people to comprehend. But, at a young age children do not understand in their current stage of development the idea of Conservation, that things do not change in quanity when they are spread out, broken or put into a different container.
