Robert Kentridge’s research examines the relationship between visual attention and visual consciousness and the perception of the material properties of objects.
In 1999, he discovered that prompting neurological patients to attend to areas in which they were blind as a consequence of their brain damage could improve their ability to respond accurately to stimuli of which they were unaware. His recent work has shown that the perception of colour as a material property occurs independently of colour experience – something at odds with long-held philosophical views about colour perception.
