are deeply ingrained assumptions, generalizations, or even pictures and images that influence how we understand the world and how we take action. For example, most students think of "class" as a teacher standing in front of the room lecturing students. This vision of a class, however, is based on an assumption developed from prior experience...and may not be a valid mental model in some classes (hint). Such biases, stereotypes, assumptions, and so on are all examples of mental models. Your psychological type influences your mental models.
