What causes motion induced blindness?
When a global moving pattern surrounds a high-contrast stationary or slowly moving target stimulus, the target disappears and reappears alternately for durations of several seconds, a phenomenon called ‘motion-induced blindness’ (MIB) (Bonneh, Cooperman, & Sagi, 2001).
How does the motion induced blindness illusion work?
Motion induced blindness illusions use apparent background motion to make static portions of the visual field temporarily disappear from view. They produce an effect that seems similar to the blind spot in the eye, or the disappearance of images in Cheshire cat illusions, but which apparently has a different cause.
When was motion induced blindness discovered?
Motion-induced blindness was originally discovered by Grindley and Townsend in 1965, followed by Ramachandran and Gregory in 1991. However it was given more attention and named when rediscovered by Bonneh, Cooperman, and Sagi in 2001.
What is a perceptual scotoma?
‘Perceptual scotomas’: A functional account of motion-induced blindness.
Is seeing motion blur normal?
Abstract. Under normal viewing conditions we are little conscious of blur in moving objects, despite the persistence of vision. Moving objects look more blurred in brief than in long exposures, suggesting an active mechanism for suppressing motion blur.
Why do things disappear when I stare at them?
Stars disappear when you look directly at them because of the anatomy of the photoreceptors in your retina. We all have two types of light-sensing cells in our eyes, the rods and the cones.
What is Bálint’s syndrome?
Bálint’s syndrome is an uncommon and incompletely understood triad of severe neuropsychological impairments: inability to perceive the visual field as a whole (simultanagnosia), difficulty in fixating the eyes (oculomotor apraxia), and inability to move the hand to a specific object by using vision (optic ataxia).
