physical illusion
   Also known as stimulus-distortion illusion. Both terms refer to an * illusion attributable to physical rather than neurophysiological or cognitive mechanisms. Some examples of physical illusions are the * mirage, the * rainbow, the * anthelic arc, the * anthelion, the * Brocken spectre, the * Ulloa circle, and the Moiré pattern. The term physical illusion is used in opposition to the terms * physiological illusion and *cognitive illusion. The term stimulus-distortion illusion is used in opposition to the term * perceiver-distortion illusion.
