When a child learns that a truck is different from a car, even though both have four wheels and a metal body, has occurred?

The accommodation has occured. Accommodation is a learning process described by Jean Piaget. This process consists in integrating new information to the existing information that we possessed of a particular topic to expand the knowledge. In this case, for example, the child already has a notion of what a car is but adds new information to differentiate between a car and a truck.

I hope my answer can help you.
