Explanation:
According to Piaget, Donny would be in the preoperational stage, which ranges from two to seven years of age. Children of this age are self-centered because <em>they often believe that people see the world as they do</em>. At this stage the children focus only on one aspect of the objects. That's why Donny pays attention only to the height of the glass without considering its width. For this reason, he considers that his mother served him less juice by having a shorter glass.
<u>The preoperational stage is also characterized in that the infant thinks that inanimate objects have the same sensory capacity as a human</u>, such as seeing, feeling or hearing.
