Image fading with retinal stabilization; Perceptual fading; Perceptual filling in; Troxler’s effect
Troxler fading refers to the apparent disappearance of a visual stimulus that remains stationary on the retina. An internet search of the terms Troxler fading or Troxler’s effect will provide the reader with many examples of this intriguing phenomenon. Although Troxler fading refers to the fading of visual images and this entry focuses on visual processing as it relates to Troxler fading, it is important to note that stimulus fading occurs in other sensory modalities; therefore, Troxler fading probably represents a general process by which the nervous stimulus habituates to redundant sensory information.
Visual images that remain stationary on the retina become dim and eventually fade from one’s awareness even though they are still physically present and can be readily seen again simply by moving the eyes or moving the stimulus. Images can be stabilized on the retina...
