The rubber square illusion
We report a new illusion of elasticity in a rigid surface. A square frame is presented behind a concentric occluding cross. When the two surfaces are rotated rigidly, the square frame appears “rubbery”, that is, it appears to contract or expand during the rotation. The rubber square illusion is related to a number of other illusory phenomena involving motion and surface stratification. It is ge...
متن کاملUnderstanding the Rotating Snakes illusion
This paper explores potential mechanisms underlying Rotating Snakes a piece of Op-Art by Kitaoka evoking a striking apparent motion illusion. The Op-Art is based on an illusion developed by Kitaoka & Ashida (2003) and is similar to previous illusions developed by Fraser & Wilcox (1979), Faubert & Herbert (1998) and Naor-Raz & Sekuler (2000). The subsequent illusions, including Rotating Snakes a...
متن کاملA new motion illusion: the Rotating-Tilted-Lines illusion.
Introduction Visual illusions are not just entertainingöthey also are non-invasive means for investigating human brain mechanisms.While they show us where our visual system fails, they can also tell us how it works. Therefore, we introduce here a new motion illusion that could represent the simplest pattern that elicits illusory motion through self-motion. It may be instrumental for future rese...
متن کاملThe Thatcher illusion: rotating the viewer instead of the picture.
Faces are difficult to recognise when presented upside down. This effect of face inversion was effectively demonstrated with the 'Thatcher illusion' by Thompson (1980 Perception 9 483-484). It has been tacitly assumed that this effect is due to inversion relative to retinal coordinates. Here we tested whether it is due to egocentric (i.e. retinal) inversion or whether the orientation of the bod...
متن کاملThe riddle of the Rotating-Tilted-Lines illusion.
Gori and Hamburger (2006, Perception 35 853-857) devised a new visual illusion of relative motion elicited by the observer's motion. We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a systematic error with respect to the two types of neurons in the primary visu...
