My PhD research focused on how camouflage patterns interfere with motion perception, and in particular whether certain types of high contrast patterning (such as stripes or zigzags) can affect speed or direction perception. This idea has been termed ‘motion dazzle’ and it has been hypothesised that it may explain some of the striking patterning seen in many animals, including zebras and many snakes, fish and insects. I am also interested more generally in the interaction between patterning, form and motion perception. My work uses human subjects and a variety of psychophysical techniques, including eyetracking and modelling.

Anna’s work asks: Why do animals have the patterning they do and how does it affect their lives? For instance, why do zebras have high contrast black and white stripes when it only makes them even more easy to see? One idea is that they may cause “motion dazzle” that makes it more difficult for predators to track them when they move. Anna’s work using psychophysics shows this may indeed be the case.
