During this stage, children are now capable of thinking in a more logical manner and their moral judgement has become subjective as <u>they now center on the motives of wrongdoers as well as on the amount of damage done when assigning blame</u>. For instance, they are able to judge another child according to the amount of damage she/he has done and whether it was done in purpose or accidentally.

They can also center on two dimensions of a problem at once and have thoughts that involve tangible objects instead of abstract ideas.
