Sherry X. Xian xx37 @ cornell.edu 203 Uris Hall      607-255-7898   [edit] Research Associate associated with: David J. Field Department: Human Development, Psychology Keywords: Behavioral Neuroscience (9), Cognitive Neuroscience (17), color vision (1), Neurophysiology (5), Systems Neuroscience (25), Vision (11) I am interested in human perception, neural representation and natural scene statistics of color. Here in Cornell, I use psychophysical methods to measure perception of chromatic illusions which provide a good tool to test hypotheses about color processing in the brain. Together with Dr. David Field, we use both psychophysical and computational methods to study the natural scene statistics with special emphasis on color. Is our trichromacy shaped by natural scenes? Can we explain the formation of different visual pathways and color opponent receptive fields with computational models based on natural scenes? During my post-doctoral study at Stanford, I studied neuronal representation of color and color appearance in V4 using neurophysiology method, e.g. single-electrode recording in Dr. Tirin Moore¡¯s lab. We will continue to collaborate on these projects and will also study the influence of eye movements to processes along different visual pathways.
