BACKGROUND In rubber hand illusions and full body illusions, touch sensations are projected to non-body objects such as rubber hands, dolls or virtual bodies. The robustness, limits and further perceptual consequences of such illusions are not yet fully explored or understood. A number of experiments are reported that test the limits of a variant of the rubber hand illusion. METHODOLOGY/PRINC...

This paper presents a novel approach for creating self-moving objects using hollow-face illusion. Given a clip of character animation, our approach generates a static object. Looking at the object at different views, the similar deformation can be observed. To accomplish this challenging mission, we give qualitative and quantitative analysis of hollow-face illusion. Methodology in computer visi...

In the Fröhlich illusion, judgements of the first position of a moving object are typically displaced in the direction of motion. The illusion has been obtained with linear motion of a small target, and with rotary motion of a spatially extended line. We compared judgements of the initial orientation of a small dot and a line that rotated around the point of fixation. The illusion was absent wi...

Imperfectly competitive macroeconomic models typically assume a symmetric equilibrium with identical firms, despite the fact that most industries are characterised by substantial degrees of firm heterogeneity. We examine how inter-firm efficiency gaps affect fiscal policy effectiveness under monopolistic competition.  2000 Elsevier Science S.A. All rights reserved.

Since the proof of Theorem 1 is rather cumbersome, it is useful to break it into several lemmas.

PURPOSE The Duncker illusion, also known as induced motion, is the illusory component of an object's motion that results from background movement. The origins of this robust phenomenon are still subject to debate. The goal of this study was to examine the role eye movements play in its generation. METHODS The Duncker illusion was generated by rear-projecting an LED target and a random-dot bac...

The closer a line extends toward a surrounding frame, the longer it appears. This is known as a framing effect. Over 70 years ago, Teodor Künnapas demonstrated that the shape of the visual field itself can act as a frame to influence the perceived length of lines in the vertical-horizontal illusion. This illusion is typically created by having a vertical line rise from the center of a horizonta...
