Document Note: Question: What are mental models?
Answer: Mental models are psychological representations of real, hypothetical, or imaginary situations that the mind constructs to anticipate events, to reason, and to underlie explanation.
Question: Who first postulated the idea of mental models?
Answer: The idea of mental models was first postulated by the Scottish psychologist Kenneth Craik in 1943.
Question: Are mental models just mental pictures or images?
Answer: No, mental models are a more general notion than just mental pictures or images. Some models cannot be visualized, and images depend on underlying models.
The document is about the theory of mental models and its application to reasoning, decision-making, and meta-reasoning. It discusses how the mind constructs mental models as a result of perception, imagination, and knowledge, and how these models are used to subserve reasoning of various sorts. The document also contrasts the model theory with the orthodox view that reasoning is based on a sort of mental logic and examines a crucial consequence of the model theory, which predicts that reasoners are programmed to commit certain systematic fallacies. Finally, the document applies models to the relatively unexplored domain of meta-reasoning, which is reasoning about what other people have reasoned, a topic that is highly pertinent to economic behavior.
Summary: The document discusses the concept of mental models in cognitive science and how they are used in reasoning. It contrasts the traditional view of reasoning based on formal rules of inference with the idea that reasoning is driven by mental models. The document presents experiments that support the existence of mental models and their influence on reasoning. It also explores how mental models are used in probabilistic reasoning and decision making. The document suggests that the existence of systematic fallacies in human reasoning can be explained by the neglect of what is false in mental models.
Mental models are psychological representations of real, hypothetical, or imaginary situations. They were first postulated by the Scottish psychologist Kenneth Craik (1943), who wrote that the mind constructs “small-scale models” of reality that it uses to anticipate events, to reason, and to underlie explanation.

When people first hear about mental models, as the epigraph from Boltzmann suggests, they suppose that they are nothing more than mental pictures or images. In fact, models are a more general notion both because some models cannot be visualized, and because images depend on underlying models. (View Highlight)
