Jason Haberman

Assistant Professor of Psychology
(901) 843-3231

Dr. Haberman is an assistant professor in psychology and a member of the neuroscience program. His research focuses broadly on visual perception, with a focus on a phenomenon known as ensemble perception. This critical heuristic, or shortcut, allows us to represent copious amounts of information using summary statistics. For example, we can readily see the ′average in the crowd,′ whether that average is motion, size, or even facial expression. Ensemble perception helps provide us with the sense of a complete visual world, even though at any given moment we are explicitly aware of only a very small fraction of it.
