Answer:
Prototype model
Explanation:
The prototype model is related to our prototype built in our memory related to the organization of things systematically. This model is closely related to our schema. The prototype is a system that is used to describe that whatever we perceived to have the complete image with qualities that are required. In psychology, the prototype is related to our cognition in which our things are organized in a graded way. We can say that something is more organized in the graded organization.
