Seiffert studies how people see and direct their attention to moving objects. The ability to follow the movement of objects is an important skill to all animals for avoiding contact with predators or coinciding actions with prey. For people, expertise at tracking is vital for many activities, from sports like basketball and football to driving a car through a busy intersection. Although a great deal is known about the limits of tracking in terms of visual input and motor outputs, the central component of this ability remains unknown. How does attention follow object movement? What is the neural implementation of this process? Why do errors in tracking occur? How is attention used in the active manipulation of moving objects? The long-term objective is to understand how visual attention interacts with motion perception and visuo-motor systems to track the motion of target objects. The methods of investigation in the Seiffert lab include human psychophysics, traditional cognitive experiments, human neuroimaging (fMRI) and brain stimulation (TMS). Grant funding from the National Eye Institute of the National Institutes of Health supports this work.
