FILLINGIN
Filling-in
In vision, filling-in phenomena are those responsible for the completion of missing information across the physiological blind spot, and across natural and artificial scotomata. There is also evidence for similar mechanisms of completion in normal visual analysis. Classical demonstrations of perceptual filling-in involve images stabilized on the retina either by means of special lenses, or under certain conditions of steady fixation. If a stimulus is entirely stabilized, its colour and lightness fade until they are no longer seen and the area fills in with the colour and lightness of the surrounding region. A famous example of fading under steady fixation is ...The above text is a snippet from Wikipedia: Filling-in
