TLDR
The results indicate that lateral inhibition may play a contributory role in illusion formation, but it is not the primary casual, mechanism.Abstract:
It has been suggested that lateral inhibitory processes, operating through the mutual inhibition and displacement of spatially adjacent contours imaged on the retina, may account for many of the classical geometric illusions. Two experiments were conducted, one using an alternative form of the Poggendorff illusion, and the other an alternative form of the Muller—Lyer, in which the adjacent contours necessary for the operation of the inhibitory mechanism were eliminated. In both instances the illusion was still found to exist, although somewhat reduced in magnitude. These results indicate that lateral inhibition may play a contributory role in illusion formation, but it is not the primary casual, mechanism.read more

Poggendorff and Müller-Lyer illusions: common effects.
TL;DR: Adaptation-level theory and the positive-context model accommodate the major findings of the present study and the relationship between the magnitude of the illusion and the dimensions of the Poggendorff figure was found to be generally in line with previous findings relating to the Müller-Lyer illusion.

Spatial distortions within the Poggendorff fig are and its variants: A parametric analysis
TL;DR: In this paper, the distance between the obliques of the Poggendorff figure relative to a pair of comparison dots during 250msec tachistoscopic presentations was investigated.

Peripheral and central components in variants of the Mueller-Lyer illusion
TL;DR: Results indicate that all of the variant forms of the Mueller-Lyer illusion share a common, central component, while the peripheral components vary as a function of the presence of converging lines in the illusion configurations.

Spatial context affects the Poggendorff illusion.
TL;DR: The results do not serve to explain the mechanisms behind the Poggendorff illusion, but they do demonstrate the importance of visual reference frames in understanding perceived misalignment.

Some informational aspects of visual perception.
TL;DR: Special types of lawfulness which may exist in space at a fixed time, and which seem particularly relevant to processes of visual perception are focused on.

Eye movements and decrement in the Muller-Lyer illusion.
TL;DR: Two experiments are reported in which a decrement in the magnitude of the Müller-Lyer illusion was found if free eye movements were allowed and saccades across the perceptually short side of the Muller-Lyers figure were found to be shorter than across the perceived long side.

The influence of optical aberrations on the magnitude of the Poggendorff illusion
TL;DR: In this paper, the amount of blurring of the retinal image can be reduced by proper selection of an artificial pupil and a chromatic filter, and the magnitude of the reduction is smaller than would be expected if the illusion was predominantly determined by blur due to optical aberration.

Binocular and stereoscopic viewing of geometric illusions.
Peter Schiller,Morton Wiener +1 more
TL;DR: It is found that the reduction of illusions under stereoscopic conditions can be attributed to both binocular rivalry and depth perception of the stimuli, and Day concluded that the interpretations of Ohwaki and Springbett regarding the retinal origin of geometric illusions thus seem unjustified.
