Frequency illusion is common in the linguistic field. Zwicky, who coined the term frequency illusion, is a linguist himself. He gave the example of how linguists "working on innovative uses of 'all,' especially the quotative use," believed their friends used the quotative "all" in conversation frequently.
The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...
The tritone paradox is an auditory illusion in which a sequentially played pair of Shepard tones [1] separated by an interval of a tritone, or half octave, is heard as ascending by some people and as descending by others. [2]
David Murdock on seemingly unrelated subjects that trigger endless research, a concept that is known as frequency illusion.
The frequency-doubling illusion is an apparent doubling of spatial frequency when a sinusoidal grating is modulated rapidly in temporal counterphase. [ 1 ] [ 2 ] Recently, it has been proposed that the illusion arises from a spatially nonlinear ganglion cell class. [ 3 ]
Salience (also called saliency, from Latin saliō meaning “leap, spring” [1]) is the property by which some thing stands out.Salient events are an attentional mechanism by which organisms learn and survive; those organisms can focus their limited perceptual and cognitive resources on the pertinent (that is, salient) subset of the sensory data available to them.
The magnitude, shape, periodicity and frequency of the TLMs will depend on many factors such as the type of light source, the electrical mains-supply frequency, the driver or ballast technology and type of light regulation technology applied (e.g. pulse-width modulation).
Troxler's fading, also called Troxler fading or the Troxler effect, is an optical illusion affecting visual perception. When one fixates on a particular point for even a short period of time, an unchanging stimulus away from the fixation point will fade away and disappear. Research suggests that at least some portion of the perceptual phenomena ...
