Why do we make errors in perception, in memory, and in our actions? Variability and uncertainty are fundamental aspects of human behaviour, which worsen with advancing age or neurological disease. In the lab we measure these factors using visual psychophysics and memory tasks, eye tracking, limb motion-tracking and force feedback. Then, using mathematical models and computer simulations, we develop and test hypotheses about the underlying brain mechanisms.
Recent research in the lab focuses on visual memory and eye movements. Our ability to remember what we have seen is surprisingly limited: we investigate how this limited resource of visual memory is distributed between features of the visual scene and how it is updated when we move our eyes.
While cognitive functions such as attention and memory are often studied from a perceptual viewpoint, they are also critical for our ability to control movement and physically interact with our surroundings. Some of the newest research in our group investigates the role of these sensory functions in the skilled control of arm and hand movements.
