- Shepard-Tische sind eine optische Täuschung, die Roger N. Shepard, ein Psychologe der Stanford University, 1990 mit der Bildunterschrift Tischedrehen („Turning the Tables“) in seinem Buch Mind Sights über die von ihm erschaffenen Wahrnehmungstäuschungen veröffentlicht hat. Es ist eine sehr wirkungsvolle optische Täuschung, bei der die tatsächliche Länge meist um 20–25 % falsch geschätzt wird. (de)
- Les tables de Shepard sont une illusion d'optique publiée pour la première fois en 1990 sous le nom « Turning the Tables » (en français : « Tourner les tables ») par le psychologue Roger Shepard dans son livre Mind Sights. C'est l'une des illusions d’optique les plus puissantes, pouvant créer des erreurs de calcul de longueur de 20 à 25 %. (fr)
- Shepard tables (also known as the Shepard tabletop illusion) are an optical illusion first published in 1990 as "Turning the Tables," by Stanford psychologist Roger N. Shepard in his book Mind Sights, a collection of illusions that he had created. It is one of the most powerful optical illusions, typically creating length miscalculations of 20–25%. To quote A Dictionary of Psychology, the Shepard table illusion makes "a pair of identical parallelograms representing the tops of two tables appear radically different" because our eyes decode them according to rules for three-dimensional objects. This illusion is based on a drawing of two parallelograms, identical aside from a rotation of 90 degrees. When the parallelograms are presented as tabletops, however, we see them as objects in three-dimensional space. One "table" seems long and narrow, with its longer dimension receding into the distance. The other "table" looks almost square, because we interpret its shorter dimension as foreshortening. The MIT Encyclopedia of the Cognitive Sciences explains the illusion as an effect of "size and shape constancy [which] subjectively expand[s] the near-far dimension along the line of sight." It classifies Shepard tables as an example of a geometrical illusion, in the category of an "illusion of size." According to Shepard, "any knowledge or understanding of the illusion we may gain at the intellectual level remains virtually powerless to diminish the magnitude of the illusion." Children diagnosed with autism spectrum disorder are less susceptible to the Shepard table illusion than typically developing children but are equally susceptible to the Ebbinghaus illusion. Shepard had described an earlier, less-powerful version of the illusion in 1981 as the "parallelogram illusion" (Perceptual Organization, pp. 297–9). The illusion can also be constructed using identical trapezoids rather than identical parallelograms. A variant of the Shepard tabletop illusion was named "Best Illusion of the Year" for 2009. Christopher W. Tyler, among others, has done scholarly research on the illusion. (en)
