Conceptual Model
An explanation, usually highly simplified, of how something works, which is formed through experience, training and instruction.
Conceptual models provide understanding
They enable people to make associations with things that are familiar in order to understand how something works and what to do if something goes wrong.
Universal ideas we all share
Examples include the files, folders and app icons found on computers. The universality of these images makes them easier to understand and use. For more abstract concepts, like deleting, we use visual metaphors, such as the trash icon. We understand the concept of throwing something in the trash, so we can use that to represent the idea of deleting items.
Mismatched conceptual models cause frustration
In the absence of a good conceptual model, we act rashly and lack appreciation of why a system works the way it does, or become frustrated if something behaves differently to how we expect it to.
Origin
