The general goal of our research is to understand and model the perception of visual patterns by normal, human, adult viewers. Our experiments isolate and model these second order processes.
Viewers constantly make decisions about the information presented by the eyes.
We examine the criteria used by viewers by imbedding stimuli in dynamic noise and determining which noise patterns are confused with the stimuli. By examining these patterns we estimate which of the several properties of the stimulus are used by the viewer in decision processes. In collaboration with Professor Mark Greenlee in Germany, we are exploring short-term visual memory processes. Present work is focusing on short-term memory for color and uses fMRI to identify important cortical areas. Publications A. Published Work 1.
