There are a million different ways to study perceptual awareness. Much of the work in the lab focuses on ambiguous stimuli and other visual illusions that involve big perceptual changes despite no change in the presented stimuli. One striking example is binocular rivalry, a phenomenon that occurs when different images are presented to the left and right eye simultaneously. Despite the fact that the two images are always being presented, people generally report only seeing one of the images at a time because the other image is completely suppressed from awareness. Our research is focused on the factors that influence the process of switching between conscious states.
