Visual cognition, perception, attention, and memory. Most of my recent research has focused on the cognitive underpinnings of our experience of a stable and continuous visual world. One line of research focuses on change blindness. These failures to notice large changes to scenes suggest that we are aware of far less of our visual world than we think. Related studies explore what aspects of our environment automatically capture attention and what objects and events go unnoticed. Such studies reveal the surprising extent of inattentional blindness - the failure to notice unusual and salient events in their visual world when attention is otherwise engaged and the events are unexpected. Other active research interests include scene perception, object recognition, visual memory, visual fading, attention, and driving and distraction. Research in my laboratory adopts methods ranging from real-world and video-based approaches to computer-based psychophysical techniques, and it includes basic behavioral measures, eye tracking, simulator studies, and training studies. This diversity of approaches helps establish closer links between basic research on the mechanisms of attention and the real-world implications and consequences of our findings.

Click on the title to check out these pictures from the classroom remodeling project in the basement. A second project to replace the elevators will begin in September. Beginning with the freight elevator, each elevator will be out of service for three months. To get quickly from one floor to another, and improve your fitness, we will encourage the use of the stairs. The repainting of the northeast stairwell has been completed, and the painter is starting on the southwest stairwell. The repainted stairwell looks astonishingly better. Be sure to thank Rick, the painter, who has been working hard on the repainting for many weeks.
