Differences Between The Scintillating and Hermann Grid Illusions
The difference between the Hermann grid illusion and the scintillating illusion is that scintillating illusions have dots already in place at the intersection, whereas there are no dots already in place at the intersections of Hermann grid illusions. Since they are so similar, the two names are commonly used interchangeably. But the scintillating illusion does not occur with an isolated intersection, as in the case of the Hermann grid; observations suggest that a minimum of 3 × 3 evenly spaced intersections with superimposed discs are required to produce the effect. This requirement suggests the participation of global processes of the kind proposed for the linking and grouping of features in an image, in addition to local processes.

Famous quotes containing the words differences between, differences and/or illusions:
“The extent to which a parent is able to see a child’s world through that child’s eyes depends very much on the parent’s ability to appreciate the differences between herself and her child and to respect those differences. Your own children need you to accept them for who they are, not who you would like them to be.”
—Lawrence Balter (20th century)
“The mother must teach her son how to respect and follow the rules. She must teach him how to compete successfully with the other boys. And she must teach him how to find a woman to take care of him and finish the job she began of training him how to live in a family. But no matter how good a job a woman does in teaching a boy how to be a man, he knows that she is not the real thing, and so he tends to exaggerate the differences between men and women that she embodies.”
—Frank Pittman (20th century)
“Swann was one of those men who, having long lived in the illusions of love, saw the well-being that they gave to many women heighten their happiness without evoking in these women any gratitude, any tenderness toward them; but in their child these men believe they feel an affection which, embodied in their very name, will make them outlast their death. When there was to no longer be a Charles Swann, there would still be a Mademoiselle Swann ... who would continue to love her departed father.”
—Marcel Proust (1871–1922)
