Gilbert’s understanding here showcases that his developmental stage, according to Jean Piaget, is at the concrete operational level.

Concrete operational is part of Piaget’s cognitive development stages, more specifically, the third stage which commonly occurs during age 7-11. It is characterized by the child’s capacity to reason and apply logical concepts – but only to physical objects.
