There are actually many models in the literature; most of the people
studying the problem seem not to be aware of each other's work.  In
addition to those already mentioned, [Feldman+Ballard] have proposed a
model inspired by [Treisman+Gelade].  (References are at the end of
this message.)  [Strong+Whitehead] have implemented a similar model.
[Fukushima]'s model is rather different.  [Koch+Ullman]'s and
[Mozer]'s models seem closest to the psychophysical and
neurophysiological data to me.  I [Chapman] have implemented
[Koch+Ullman]'s proposal successfully and used it to model in detail
the psychophysically-based theories of visual search due to
[Treisman+Geldade, Treisman+Gormican].  My thesis [Chapman] describes
these and other models of attention and tries to sort out their
relative strengths.

It's probably time for someone to write a review article.
