D. Alexander Varakin

Assistant Professor of Psychology

General Interests
"In general, I am interested in how visual processes contribute to cognition as a whole, how cognition as a whole impacts visual processes and how these interactions are shaped by, and influence, the way we think about and act in the world.

Much of my research has been on failures of visual awareness. People seem to keep track of a very small amount of visual information from one view to the next; that is, people don't see everything they think they do. There are numerous real-world implications for this research, for example, in the area of computer interface design. In more recent work, I have been investigating how people mentally represent pictures and other kinds of visual information in short- and long-term memory. In one series of experiments, a colleague and I demonstrated that the act of recognizing previously viewed pictures may not draw upon memory representations that are very picture-like. In other words, the memories we use to recognize photographs are not 'photographic'."
