Answer:
Luis is in the concrete operational stage of cognitive development
Explanation:
Psychologist Jean Piaget, was known for his work on child development. One of his most important theories is the theory of cognitive development.
As per Piaglet’s theory, Luis is in the concrete operational stage, this occurs around 7 and 11 years old.
During this stage, children develop logical thoughts, their thinking becomes very concrete and they are able to articulate their feelings, ideas and solve problems using dialogue.
They start to understand logic and inductive reasoning; they are able to go from a specific experience to a general principle. They are also able to concentrate on many aspects of the a situation and process different things at the same time.
Children at this stage also start to take perspective of others, and start trying to see things the way others see them.
