Research Description:

Low-level and object-salient features influence perception, but questions remain about how these features interact. We study the effects of contrast, luminance, and orientation of visual features on target detectability, and are pursuing experiments that investigate these features' relation to figure-ground assignment.

We are also interested in how people learn to identify ambiguous objects using both behavioral and functional imaging techniques.
