The Scintillating Grid Illusion
Disk-shaped luminance increments were added to the intersections of a Hermann grid consisting of medium grey bars on a black background. Illusory spots, darker than the background, were perceived as flashing within the white disks with each flick of the eye. This striking phenomenon may be referred to as the scintillating grid illusion. We determined the conditions necessary for cancelling the ...
متن کاملThe scintillating grid illusion in stereo-depth
The dark scintillating dots occurring on a gray-on-black, modified Hermann grid [Schrauf, M., Lingelbach, B., & Wist, E. R. (1997). The scintillating grid illusion. Vision Research, 37, 1033-1038] were studied in stereo-depth by assigning various degrees of disparity to the white inducing disks. Dependent on the sign of disparity, the disks and the dark illusory spots within them appeared to li...
متن کاملThe scintillating grid illusion is enhanced by binocular viewing
The scintillating grid illusion is an intriguing stimulus consisting of a grey grid on a black background, with white discs at the grid intersections. Most viewers perceive illusory "scintillating" black discs within the physical white discs, especially at non-fixated locations. Here, we report for the first time that this scintillation percept is stronger when the stimulus is viewed binocularl...
متن کاملThe shape of luminance increments at the intersection alters the magnitude of the scintillating grid illusion
The scintillating grid illusion refers to an illusory perception of black spots on the luminance increments at the intersections of gray grids on a black background. In this study, we examined how the shape of luminance increments modulated the strength of the illusion. In Experiment 1, we concurrently controlled the size and shape of luminance increments, and found significant reduction of the...
متن کاملA Neural Model of the Scintillating Grid Illusion: Disinhibition and Self-Inhibition in Early Vision
A stationary display of white discs positioned on intersecting gray bars on a dark background gives rise to a striking scintillating effect--the scintillating grid illusion. The spatial and temporal properties of the illusion are well known, but a neuronal-level explanation of the mechanism has not been fully investigated. Motivated by the neurophysiology of the Limulus retina, we propose disin...
