The Visual Psychophysics Group at the University of Plymouth develops and applies psychophysical methods, such as detection/discrimination threshold measurements or neuronal adaptation, to study visual perception in healthy subjects and clinical populations. The research interests of this group range from basic research to understand shape, object, colour, motion and face perception, to the development of efficient clinical tests for specific ocular diseases, such as amblyopia, age-related macular degeneration, and glaucoma.
