Another explanation is the "framing-effects hypothesis", which says that the difference in the separation or gap of the horizontal lines from the framing converging lines may determine, or at least contribute to the magnitude of the distortion. The Ponzo illusion is one possible explanation of the Moon illusion, as suggested by Ponzo in 1912. [3]
The widely accepted interpretation of, e.g. the Poggendorff and Hering illusions as manifestation of expansion of acute angles at line intersections, is an example of successful implementation of a "bottom-up," physiological explanation of a geometrical–optical illusion. Ponzo illusion in a purely schematic form and, below, with perspective clues
The Ponzo illusion is an example of an illusion which uses monocular cues of depth perception to fool the eye. But even with two-dimensional images, the brain exaggerates vertical distances when compared with horizontal distances, as in the vertical–horizontal illusion where the two lines are exactly the same length.
The Poggendorff illusion (1860) involves the misperception of the position of one segment of a transverse line that has been interrupted by the contour of an intervening structure (here a rectangle). Ponzo illusion: In the Ponzo illusion (1911) two identical lines across a pair of converging lines, similar to railway tracks, are drawn. The ...
Ponzo illusion: Top line is perceived as larger than the bottom line, though they are identical in size. Size constancy is one type of visual subjective constancy. [3] Within a certain range, people's perception of one particular object's size will not change, regardless of changes in distance or the video size change on the retina.
Art historians say Leonardo da Vinci hid an optical illusion in the Mona Lisa's face: she doesn't always appear to be smiling. There's question as to whether it was intentional, but new research ...
An auditory illusion driving social media insane has a surprisingly simple solution — but that certainly doesn’t make it any less entertaining.
The Jastrow illusion has been compared with other optical illusions, such as the Fat Face illusion, [7] [8] the Leaning Tower illusion and the Ponzo illusion. [9] [10] Masaki Tomonaga, a researcher at Kyoto University, compared the Jastrow Illusion with the so-called Fat Face Illusion.
