In the Laboratory for Integrative Vision, we are interested in understanding the many factors that influence how visual processing unfolds. Although it may seem we look out of our heads to illuminate the world around us, complex neural processing occurs between the time when photons hit our retinas and when we perceive the world around us. Of specific interest to our lab is attention, a psychological concept relating to the idea that at any one time only a subset of visual input is selected for processing. Many factors, including the nature of the incoming input, an observer’s current goals, and recent experiences all play a role in determining how selection occurs. We use methods such as psychophysics, eye-tracking, and EEG/ERP to better understand how attentional mechanisms operate over space and time, as well as across individuals.
