I've worked on topics including retinal anatomy (21,24,39),
retinal image processing (31,35,38), texture perception (43,45), and
models for choice behavior (14,15,17,19,45). Now I am studying:

Metacontrast. This is a type of visual masking in which the
visibility of a brieflyflashed target stimulus is reduced by a second
stimulus, the mask, that is also briefly flashed, but slightly later and
at a different location in the visual field. I'm interested in the effects
of target-mask similarity on strength of masking. One recent finding is
that some stimulus displays can produce a form of motion perception in
which no motion is experienced consciously, but certain perceptual
consequences of motion occur nevertheless, showing that the original
motion was registered by the visual system, but not a level accessible to
consciousness.

Ranking Models and Irreversibility. Suppose two people A and B
repeatedly express their preferences for the same three objects x,y,z by
rank ordering them, and that whenever A produces any given ranking, say x
y z, B always perversely produces exactly the opposite ordering -- here z
y x. In that case we say that A and B have "opposite preference systems."
Some mathematical models for ranking have the curious property that
whenever the model predicts any given system of preference probabilities,
it can never predict the opposite of that system. Such a model is said to
be "completely irreversible." I'm trying to determine which classes of
models do and do not have this property.
