Explanation:

According to Jean Piaget's theory of cognitive development, there are four stages of cognition.

At this stage, children are able to deal with abstract concepts and theories, to think creatively, and to use logic to solve problems. The clear indication that the child has reached this stage is precisely the child's ability to reason in a non-concrete way, that is, to use abstract thinking.
