Author Biography

Steven Yantis is Professor and Chair of the Department of Psychological and Brain Sciences at Johns Hopkins University, with secondary appointments in the Departments of Cognitive Science and Neuroscience.  He studied experimental psychology as an undergraduate at the University of Washington in Seattle, and later he received a PhD in Experimental Psychology at the University of Michigan. Following a year as postdoctoral fellow at Stanford University, he joined the faculty at Johns Hopkins University, where he has been ever since. Yantis has research interests that include visual perception, attention, and cognition.  Members of the Yantis laboratory measure behavior (response time, eye movements) and brain activity (functional MRI) as people carry out tasks that probe perception and attention. He has taught a variety of courses in human perception and attention for more than two decades. In Visual Perception: Essential Readings (Psychology Press, 2000), Yantis assembled 25 articles published over 100 years that laid the foundations of the field, and he is the volume editor of the Stevens Handbook of Experimental Psychology (3e): Volume 1: Sensation and Perception (Wiley, 2002). Yantis received the Early Career Award from the American Psychological Association in 1994 and the Troland Research Award from the National Academy of Sciences in 1996.
