We say we see with our eyes but, really, we see with our brain. Our brain organizes the visual information that falls on our retina and constructs a coherent precept of the outside world; without the brain we would be blind. Visual awareness is thus determined by the way the brain interprets visual input. My main interest is on how this interpretation is influenced by what we have seen before (perceptual memory) and what we want to see (will-full attentional control).

Multi-interpretable stimuli provide a tool to study changes in visual awareness without a change in the actual visual input. We study how the perceptual interpretation of multi-interpretable stimuli is influenced by previous exposure to the stimulus or by voluntarily favoring a certain percept. We use brain-imaging techniques (EEG, fMRI) to measure brain activity related to visual awareness and we use novel multivariate data-analysis methods to predict visual awareness based on these brain activity measures.
