Here we address the question by modelling not human physiology or perception directly as is typically the case but our natural visual world and the need for robust behaviour. Artificial neural networks were trained to predict the reflectance of surfaces in a synthetic ecology co...

We investigated why we have no perception of a smeared image resuhing from the reduction in contrast (grey-out) occurring at the retina during saccadic eye movements. By turning on light in the experimental room only during the eye movement. we were able to show that this grey-out was perceived as a smeared image of the visual scene. However, when the exnerimental room was illuminated before an...
