Perception, 1981
In the standard version of the Poggendorff figure a transversal intersects two parallel verticals and the segment of the transversal between the two intersection points, A and B, is not shown.

Is the Moon Illusion an Illusion?

2012
The Moon Illusion refers to the fact that the moon (or sun) appears larger near the horizon than higher in the sky.

Perceptual and Motor Skills, 1975
16 college males participated in a study exploring active and passive illusions in touch. Analogs to 2 primary and 2 secondary visual illusions were constructed for active and for passive tactual presentation. Tactual illusory effects similar to those one would predict from vision were found in the active mode of presentation of the Müller-Lyer, and ...
