Answer:

This is an example of egocentrism.

Explanation:

Therefore, if they close their eyes and stop seeing you, they believe that means you can't see them too. That is what is taking place in the passage we are analyzing here. Jeremiah is only three years old, which means he is still in the preoperational stage. He is surprised that his older brother is able to see him when he thinks he is "hiding" so efficiently. Jeremiah is giving us an example of egocentrism.
