Current Projects



Studying the impact of bottom-up versus top-down scene context on visual search behavior in an eye tracking paradigm



Exploring the impact of a retro cue on fragile (rather than working) memory storage of stimulus features



Continuing an investigation into the interactions between illusory color spreading, luminance, surface area, and priming on figure-ground reversibility of semantic and abstract images



Examining color spreading illusions under a various global contexts more similar to the real-world



Exploring the impact of figure-ground reversibility using the watercolor illusion



Studying the manifestation of boundary extension in a more ecologically valid virtual reality setting






Using eye tracking to study visual search and social gaze



Boundary extension in the real-world: is this error of commission real or lab created?
