<unk>  is a phenomenon in which people who are perceptually blind in a certain area of their visual field demonstrate some response to visual stimuli, without any qualitative experience ('qualia'). In Type 1<unk>  subjects have no awareness whatsoever of any stimuli, but yet are able to predict, at levels significantly above chance, aspects of a visual stimulus, such as location, or type of movement, often in a forced-response or guessing situation. Type 2<unk>  is when subjects have some awareness of, for example, movement within the blind area, but no visual percept, or quale. This may be caused by, for example, the person being aware of their eyes' tracking motion which will function normally.<unk>  is caused by injury to the part of the brain responsible for vision.
