“…Shimojo 9 used a mirror ball to create a moving mask of bright spots across a room, and was able to cause the perceptual disappearance of a live person in their interactive museum display. Another demonstration of MIB in real life was reported by Inoue, Yagi and Kikuchi 10 , where they induced MIB by superimposing a target over the optic flow of a movie, filmed from the driver’s point of view while travelling in a car. Perceptual disappearance was induced much more often while travelling in forward motion compared to viewing the target over a still frame.…”

Motion Induced Blindness (MIB) is a well-established visual phenomenon whereby highly salient targets disappear when viewed against a moving background mask. No research has yet explored whether contracting and expanding optic flow can also trigger target disappearance. We explored MIB using mask speeds corresponding to driving at 35, 50, 65 and 80 km/h in simulated forward (expansion) and backward (contraction) motion as well as 2-D radial movement, random, and static mask motion types. Participants (n = 18) viewed MIB targets against masks with different movement types, speed, and target locations. To understand the relationship between saccades, pupil response and perceptual disappearance, we ran two additional eye-tracking experiments (n = 19). Target disappearance increased significantly with faster mask speeds and upper visual field target presentation. Simulated optic flow and 2-D radial movement caused comparable disappearance, and all moving masks caused significantly more disappearance than a static mask. Saccades could not entirely account for differences between conditions, suggesting that self-motion optic flow does cause MIB in an artificial setting. Pupil analyses implied that MIB disappearance induced by optic flow is not subjectively salient, potentially explaining why MIB is not noticed during driving. Potential implications of MIB for driving safety and Head-Up-Display (HUD) technologies are discussed.

These bistable phenomena allow subjects to experience varying phenomenology while receiving physically 17 constant visual input, thus, they can help delineate the neural correlates of consciousness by dissociating physical stimuli from 18 conscious perception 2, 3, 6 . 19MIB has been extensively studied under stimulus parameters designed to optimise perceptual disappearances [6][7][8] . While 20 it has been suggested that MIB may happen in the real world 1 , no research has yet explored MIB using parameters that 21 approximate those experienced in real world movement. To date only two predominantly anecdotal studies have explored 22 whether MIB may occur in the real world. Shimojo 9 used a mirror ball to create a moving mask of bright spots across a room, 23 and was able to cause the perceptual disappearance of a live person in their interactive museum display. Another demonstration 24 of MIB in real life was reported by Inoue, Yagi and Kikuchi 10 , where they induced MIB by superimposing a target over the 25 optic flow of a movie, filmed from the driver's point of view while travelling in a car. Perceptual disappearance was induced 26 much more often while travelling i...

“…The illusion manifests itself as transient episodes of perceptual blindness, leading observers to experience the sudden disappearance of the stationary targets. Beyond its application in psychophysical experiments, its importance is highlighted by using it in real-life simulations 23,24 . In the context of MIB, the brain appears to prioritize the more salient visual information (in this case the motion of the background pattern), leading to the disappearance of the peripheral stationary target from awareness 22 .…”

Polar angle asymmetries (PAAs), the differences in perceptual experiences and performance across different regions of the visual field are present in various paradigms and tasks of visual perception. Currently, research in this area is sparse, particularly regarding the influence of PAAs during perceptual illusions, highlighting a gap in visual cognition studies. We aim to fill this gap by measuring PAAs across the visual field during an illusion applied to test conscious vision widely. Motion-induced blindness (MIB) is an illusion when a peripheral target disappears from consciousness as the result of a continuouslymoving background pattern. During MIB we separately measured the average disappearance time of peripheral targets in eight equidistant peripheral visual field positions. Our results indicate a significant variation in MIB disappearance times as a function of peripheral target position. Specifically, we found shorter disappearance times along cardinal compared to oblique directions, and along the horizontal compared to the vertical meridian. Our results suggest specific consistencies between visual field asymmetries and conscious visual perception.
