Motion-induced blindnessMotion-induced blindness was originally discovered by Ramachandran and Gregory in 1991.However it was given more attention and named when rediscovered by Bonneh, Cooperman, and Sagi in 2001. The researchers originally attributed its causes strictly to attentional mechanisms, seeing the visual system as operating in a winner-takes-it-all manner.
Troxler's fading, discovered by Troxler in 1804, is a very similar phenomenon in which an object away from one's focus of attention disappears and reappears irregularly. There is no necessity for a moving background for this illusion to occur. Other similar phenomena in which salient stimuli disappear and reappear include binocular rivalry, discovered as early as 1593, monocular rivalry,and flash suppression.
As the phenomenon was discovered so recently, researchers have speculated about whether MIB occurs outside the laboratory, without being noticed as such. Situations such as driving, in which some night drivers should see stationary red tail lights of the preceding cars disappear temporally when they attend to the moving stream of lights from oncoming traffic may be case points.
In this demonstration the observer focuses at the flickering green dot in the middle. After about 10 seconds, the observer sees one, two or all three of the static yellow dots arranged at the corners of an imaginary equilateral triangle disappear and then reappear. These disappearances and reappearances continue pseudo-randomly for as long as the observer cares to look. (Wikipedia)
If you concentrate your eyes on the moon, you’ll experience the disappearance of the stars.
