Perception, 2015
Effect of perceptual inversion on illusion figures seen monocularly was explored using Ponzo and Muller-Lyer stimuli. It was found that inversion nullified the Ponzo effect but not the Muller-Lyer effect. This suggests that the determinants of the two illusory effects differ in their origin.

Visual Neuroscience, 2006
The discoloration illusion, a new visual phenomenon, is described. This phenomenon originates from the juxtaposition of eight chromatic parallel contours on a white background, creating a luminance gradient and enclosing a light red region. Under these conditions, the inner region appears white: the light red discolors and appears white with both ...

The Okuma Illusion: A New Illusion of Leaning
Perception, 2012A new illusion demonstrating the perception of tilted objects is reported. Physically, all the objects in a rotated image should tilt at the same degree. We, however, found that the tilt of objects in a rotated frame is perceived differently. We tested several objects and found that this phenomenon is especially noticeable when an element in the image

The Poggendorff Illusion: An Illusion of Linear Extent?
Perception, 1981In 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. The two portions of the transversal outside the parallels then seem to be misaligned. Besides this illusion of direction, there is also an illusion of size, the

Is the illusion of conscious will an illusion?
Behavioral and Brain Sciences, 2004This book is a tour de force in showing that what we believe to be actions dictated by conscious will are not, in fact, wholly dictated by conscious will. However, Wegner has fallen into the trap of making claims that go beyond his data to make his case more compelling and newsworthy. Psychology needs to be informed by common sense.

Archives of General Psychiatry, 1984
There are several diseases, including schizophrenia, alcoholism, and opiate addiction, for which the long-term prognosis is subject to disagreement between clinicians and researchers and also among researchers. Part of this disagreement may be attributable to a difference in the populations they sample.

Vision Research, 1976
Abstract Four experiments were performed to test for the occurrence of perceived central fusion of vertically disparate stimuli. Two of these employed the method of Signal Detection Theory in order to measure the sensitivity of observers in discriminating disparate from non-disparate cyclofusional stimuli along the horizontal meridian.

Is the Moon Illusion an Illusion?
2012The Moon Illusion refers to the fact that the moon (or sun) appears larger near the horizon than higher in the sky. It is called an illusion because the angular size of the celestial bodies does not change in different parts of the sky (apart from a slight shrinkage and shape distortion near the horizon owing to refraction).

Real illusion or illusory illusion: The method of Faux Illusions for verifying new illusions
Bioscience Hypotheses, 2008Abstract Here the problem of the verification of new illusions is addressed. Subtle perceptual illusory experiences can be hard to recognize, meaning that it can be difficult or impossible for an introspecting psychologist to convey a new illusion or verify that other people experience a new illusion without polluting other people's experience by ...
