Abstract
IF a dimly illuminated target is steadily fixated in a darkened room, all or parts of the target may seem to disappear and then reappear. There have been several reports that such disappearances are “structured” or “meaningful”1–3. For example, whole lines presumably tend to disappear and reappear as units. Such “structured” disappearances have also been reported in stabilized retinal image and after-image conditions4. Hebb interpreted the seeming ubiquity of whole line disappearances as support for the idea that the whole line is a basic perceptual “unit” in complex visual percepts.
