Positive illusions are associated with unrealistic optimism about the future and an inflated assessment of one's abilities. They are prevalent in normal life and are considered essential for maintaining a healthy mental state, although, there are disagreements to the extent to which people demonstrate these positive illusions and whether they are beneficial or not. But whatever the situation, i...

These experiments were designed to investigate illusions of movements of the fingers produced by combined feedback from muscle spindle receptors and receptors located in different regions of the skin of the hand. Vibration (100 Hz) applied in cyclic bursts (4 s 'on', 4 s 'off') over the tendons of the finger extensors of the right wrist produced illusions of flexion-extension of the fingers. Cu...

In everyday life, many diverse bits of information, simultaneously derived from the different sensory channels, converge into discrete brain areas, and are ultimately synthetized into unified percepts. Such multisensory integration can dramatically alter the phenomenal experience of both environmental events and our own body. Crossmodal illusions are one intriguing product of multisensory integ...

The computational problem of motion perception involves early processes of computing image motion from the retinal images, and later processes of interpreting the image motion in terms of the 3D motion of the observer and the objects in the scene. At the level of mathematical abstraction, computing image motion amounts to an estimation problem and can be analyzed using the tools of statistics a...

Most previous research on illusions of control focused on generative scenarios, in which participants' actions aim to produce a desired outcome. By contrast, the illusions that may appear in preventive scenarios, in which actions aim to prevent an undesired outcome before it occurs, are less known. In this experiment, we studied two variables that modulate generative illusions of control, the p...

Inconsistent information from different modalities can be delusive for perception. This phenomenon can be observed with simultaneously presented inconsistent numbers of brief flashes and short tones. The conflict of bimodal information is reflected in double flash or fission, and flash fusion illusions, respectively. The temporal resolution of the vision system plays a fundamental role in the d...

It has been suggested that there maybe no olfactory illusions. This manuscript examines this claim and argues that it arises because olfactory illusions are not typically accompanied by an awareness of their illusory nature. To demonstrate that olfactory illusions do occur, the relevant empirical literature is reviewed, by examining instances of where the same stimulus results in different perc...

We have accepted a total of 42 articles for this special issue, which together have earned 80,000 views as of June 2, 2016, showing the popularity of illusions as a subject for both authors and readers. The papers address conceptual and perceptual illusions, typically using psychophysical, computational, or phenonomological methods, or some mixture of these. Narrowly defined, an illusion is a m...

Recently, a number of philosophers have argued that property illusions—cases in which we perceive property, but is not the it seems to us be virtue our perceptual experience—and veridical veridically an object's properties, experience some specific nonetheless unsuccessful or illusory—can occur. I defend contrary view. First, maintain there are compelling reasons conclude illusions and cannot o...
