An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book",some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

Kinesthetic aftereffect: One phenomenon or two? | SpringerLink - Kinesthetic (figural) aftereffect (KAE) studies almost always involve an aftereffect-inducing stimulus (I) that is wider or narrower than the test stimulus (T). I ≠ T has been presumed to be a necessary condition for KAE's occurrence. We contend that this, in part, reflects researchers' failure to use an appropriate control condition (here, I = T): Effects due to size difference and

Figural aftereffects in the perception of faces | SpringerLink - We examined figural aftereffects in images of human faces, for which changes in configuration are highly discriminable. Observers either matched or rated faces before or after viewing distorted images of faces. Prior adaptation strongly biases face perception by causing the original face to appear distorted in a direction opposite to the adapting distortion. Aftereffects transferred across

Hans Wallach - Wikipedia - Hans Wallach (November 28, 1904 - February 5, 1998) was a German-American experimental psychologist whose research focused on perception and learning. Although he was trained in the Gestalt psychology tradition, much of his later work explored the adaptability of perceptual systems based on the perceiver's experience, whereas most Gestalt theorists emphasized inherent qualities of stimuli

A mathematical theory of optical illusions and figural aftereffects - If it is assumed that spurious enhancement of receptive field excitations near the intersection of image lines on the retina contributes to the cortical determination of the geometry of two-dimensional figures, an equation based on the least-squares fit of data points to a straight line-can be obtained to represent theapparent line. Such a fit serves as anextreemum on the precision with which

FIGURAL AFTEREFFECTS - Psychology Dictionary - The extent of figural aftereffects increases with the amount of exposure to the first figure, beginning with an exposure of two to five seconds anTEShing a maximum after about one minute.

Two well-known theories of figural after-effects (FSEs) have been stated in terms of the physiological proc-esses set up as the result of inspecting a Egure.

Figural aftereffects; an investigation of visual processes - Prolonged inspection of an outline figure, , an oblong or a circle, gives rise to certain aftereffects whose characteristics are revealed as apparent distortions in test figures subsequently inspected. The affected region of the visual field is said to be satiated by the process of inspecting the original figure. The character and degree of such satiation are measured by the extent and

Effects of inspection figure persistence on a figural aftereffect - Four experimental and four control Ss were presented monocularly with a large white circle on a black background (Inspection figure). Then Ss were asked to switch to the opposite eye and make relative size judgments of two smaller circles, equal in size, one of which (the T-figure) was centered on the same point as the I-figure. For FAE control Ss the I-figure was removed during and subsequent

The Phi Phenomenon: The Optical Illusion Your Brain Creates - The phi phenomenon (φ) is an optical illusion that our brain generates by making us believe that a fixed figure is in motion. The Gestalt school defined and coined this term in 1912. This, in turn, helped to demonstrate an important concept, that perception goes beyond our senses, and beyond what we see or feel

Kinesthetic aftereffect: One phenomenon or two? | SpringerLink - Two different KAE phenomena apparently exist: an aftereffect induction phenomenon and a contrast effect.
