I’m interested in the basis of human visual perception. My research examines this using techniques derived from behavioural psychophysics, along with computational modelling, eye tracking and functional magnetic resonance imaging (fMRI).
A particular focus of my research is the nature of our peripheral vision and ‘visual crowding’, the deleterious effect of clutter on object recognition. I have examined crowding both in adult vision, where it is particularly prominent in the peripheral visual field, and in children, where it is elevated in central vision (around fixation) and particularly so for children with amblyopia (‘lazy eye’). I also have active interests in the perception of motion, depth, position, and density/numerosity, as well as visual adaptation, saccadic eye movements, face recognition, change detection and attention.
