ABSTRACT
The use of computational models to simulate unimpaired human psychological behavior
is now fairly common, and use of such models to simulate impaired behavior has also
increased. In this article I discuss the relation of computational models to behavioral
investigation and to theory, with a view to clarifying what a computational model
is, and what its value may be in investigating unimpaired and pathological human psychological
behavior.

It may be worth noting that a mathematical model is a particular type of computational
model, in which the behavior of the model can be fully described in terms of an equation
or set of equations. This property is not typically true of other types of computational
models. There are also certain other typical differences between mathematical and
other computational models, but discussion of these is beyond the scope of the present
article.
