An afterimage in general is an optical illusion that refers to an image continuing to appear after exposure to the original image has ceased. Prolonged viewing of the colored patch induces an afterimage of the complementary color (for example, yellow color induces a bluish afterimage).
A classical example for a physical distortion would be the apparent bending of a stick half immersed in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). [4] An example for a physiological fiction is an afterimage. [4]
This theory also explains negative afterimages; once a stimulus of a certain color is presented, the opponent color is perceived after the stimulus is removed because the anabolic and catabolic processes are reversed. For example, red creates a positive (or excitatory) response while green creates a negative (or inhibitory) response.
Afterimage on empty shape (also known as color dove illusion) This type of illusion is designed to exploit graphical similarities. Ambiguous image: These are images that can form two separate pictures. For example, the image shown forms a rabbit and a duck. Ambigram: A calligraphic design that has multiple or symmetric interpretations. Ames ...
Experiments by Zeki et al., [37] using the Land Color Mondrian, have shown that when normal observers view, for example, a green surface which is part of a multi-colored scene and which reflects more green than red light it looks green and its afterimage is magenta. But when the same green surface reflects more red than green light, it still ...
For example, after staring at a computer screen and looking away, a vague afterimage of the screen remains in the visual field. A stimulus consistently produces the same afterimage , which is dependent on the stimulus intensity and contrast , the time of fixation , and the retinal adaptation state .
Experientially basic and primarily spatial image schemas such as the Containment schema and its derivatives the Out schemas lend their logic to non-spatial situations. For example, one may metaphorically use the term out to describe non-spatial experiences: (4) Leave out that big log when you stack the firewood.
Another example of a bistable figure Rubin included in his Danish-language, two-volume book was the Maltese cross. A 3D model of a Rubin vase Rubin presented in his doctoral thesis (1915) a detailed description of the visual figure-ground relationship, an outgrowth of the visual perception and memory work in the laboratory of his mentor, Georg ...
