of routines, scripts, and schemas to deal with the world. When a
person repeatedly
observes similar situations, such as the behavior of
authority figures, the mental models of such situations are reinforced,
and, very importantly, associations are constantly strengthened
between the mental models of these situations and the responses that
are observed as being typical. The mental models become mental ref-
erence models.
As we become more familiar with particular behaviors after
repeated exposures, we find them to be more acceptable — even per-
missible and desirable — as responses to situation types in whose
contexts they have been observed.
Examples include how a store
clerk deals with an angry customer, how an office worker chooses to
participate in office gossip, how a loan officer handles a personal
loan application with credit problems, and so on. The more familiar
we are with a situation type (i.e., the stronger our associations are),
the more automatic is our response. When associations are very
strong, we tend to react without reflection. When a person meets with
any situation, he relies on his library of
mental reference models to
interpret the situation and decide how to handle it. We hypothesize
that the selection of the mental models that guide the situation is
based primarily on the strength of associations; that is, the number
and intensity of exposures to similar situations, real or fictitious.
However, as may be apparent from earlier discussions, the
situation-at-hand will be different in some respect from any previous
situation, and therefore the mental reference models need to be mod-
ified, primarily by conceptual blending.
On Mental Models
Kenneth Craik (1943) suggested that the mind constructs “small-
scale models” (mental models) of reality
that it uses to anticipate
events. It has since become evident that such mental models are also
used to generate decisions and actions. People construct mental
models from what they perceive or imagine or from readings and
communications with people. Mental models may be visual images
or abstract representations of situations. We use the broader repre-
sentation of “mental models” to mean representations in the mind
of situations, events, etc., that have been experienced or are learned
from other sources. These are
real mental models. We also include
mental models that result from thought experiments and self-

imagined situations. These are
imaginary mental models, and may
be untrue.
Mental model structures may be analogous to the structure of the
situations that they represent, unlike, say, the abstract structure of
logical equations used in formal rule theories. Many recent studies
present experimental evidence that corroborates
the predictions of
the mental model theory of reasoning, while others suggest revisions
and modifications to some of the theory’s tenets to accommodate new
data. Critics of the model theory include proponents of alternative
theories such as deduction based on inference rules. The controversy
about whether people reason by relying on models or on inference
rules has led to better experiments and to developments of the mental
model theory of thinking and reasoning in novel domains.
