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

The effects of the motion path and the length of the variable segment in the Poggendorff illusion without parallels
TL;DR: This article showed that small but consistent, errors in an alignment task occur for oblique lines when the variable stimulus is a line segment but not when it is a dot, this discrepancy could have been due to the structure of the variable stimuli or its path of motion.

Evidence for a significant contribution of interactions between oriented line segments in the Tolansky version of the Poggendorff illusion
TL;DR: It was found that the addition of parallel inducing lines significantly increased illusions, but only when transverse pointers were line segments rather than dots, which was consistent with previous research, which has shown that line interactions are a significant component of Poggendorff effects.

Three-dimensional Müller-Lyer illusion.
TL;DR: Three-dimensional variants of the Müller-Lyer pattern were created to address the question of where along the path of information flow in the visual system the illusion might occur, and it was shown that this 3-D illusion is homologous with the classical illusion, and that the two may share a common causal mechanism.

Retinal Mechanisms in the Perception of Subjective Contours: The Contribution of Lateral Inhibition
TL;DR: Subjective contour stimuli were displayed under an intermittent light source, with rapid onset and slow offset as has been shown to increase lateral inhibitory interactions by allowing summation of neural onset transients, and a sample of forty subjects reported increased subjective contour clarity and brightness effects under these exposure conditions.

The effect of a moving dot transversal on the Poggendorff illusion
TL;DR: In this article, responses to three types of transversal were measured and it was concluded that the magnitude of the moving dot effect could not be attributed to temporal sequence, and an eyemovement hypothesis was suggested instead.

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.
