My doctoral and postdoctoral research focused on neural mechanisms of spatial and color perception, particularly on how these mechanisms are compromised by aging. This work combined psychophysical techniques with advanced optical imaging to test specific hypothesis about visual performance throughout the life span. These lines of research remain among my interests, and include new projects under development.
More recently, I extended this work to individual differences in visual perception and how differences directly alter an individual’s every day experience of, and interactions with, the natural world. For instance, if color appearance relies on spatial cues (e.g., perceived 3-D structure or luminance contours; Elliott & Shevell, 2013), how is color appearance different for individuals with reduced spatial vision in one eye (e.g., amblyopia) or both eyes (e.g., due to aging)? In addition, studies determined how individual differences in perception relate to individual behaviors in areas beyond vision, such as social cognition. A current line of research focuses on how visual processes mediating face perception are influenced by social attitudes about members of a perceived out-group.
