 They describe both as visual attributes which are perceived in a certain region of the visual field regardless of being in the background (in the same manner as colour, brightness or texture) thus inducing target disappearance.They argue that because in both MIB and PFI the disappearance; or the incorporation of the background motion stimuli; becomes more profound with an increase in eccentricity, decrease in contrast and when perceptual grouping with other stimuli is controlled for; the two illusions are very likely to be a result of intermutual processes.Since MBI and PFI show to be structurally similar, it seems plausible that MIB can be a phenomenon responsible for completing missing information across the blind spot and scotomas where motion is involved.
