The concept of backward masking originated in psychoacoustics, referring to temporal masking of quiet sounds that occur moments before a louder sound. In cognitive psychology , visual backward masking involves presenting one visual stimulus (a "mask" or "masking stimulus") immediately after a brief (usually 30 ms) "target" visual stimulus resulting in a failure to consciously perceive the first stimulus. [1]
"Perceptual Masking" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings). Descriptors are
Although electrical stimulation produces an abnormal temporal response in the auditory nerve, temporal Tinnitus: Processing of Auditory Phantom Sound☆. In forward masking an early stimuli takes hold over consciousness (resulting in top-down activation) that prevents a later stimuli from overshooting the selective attention threshold, thus the latter remains subliminal (limen is threshold in Latin, so sub-liminal is literally below threshold). Visual masking is a phenomenon of visual perception. It occurs when the visibility of one image, called a target, is reduced by the presence of another image, called a mask.
with similar time constants. In psychoacoustics forward masking and other temporal phenomena are typically explained by integration over a temporal window. The masking stimulus is presented either before the test stimulus (forward masking), at the same time From: auditory masking in A Dictionary of Psychology ». Forward masking occurs when a sound (the signal) cannot be perceived due to the presence of a preceding sound (the masker). In a typical adult experiment, 3. The iso-forward masking contour near the threshold of the masking effect across masker frequencies approximates a fiber's frequency threshold curve ( FTC).

As t increases, there is less masking; although Forward masking is greater the nearer in time to the masker that the signal occurs. This is illustrated in the left panel of Figure 12 .
It also simulates published data showing only small threshold shifts when a psychophysical forward-masking paradigm is applied to AN responses. The model is extended to simulate a simple but physiologically plausible mechanism for making threshold decisions based on coincidental firing of a number of AN fibers.
Yet, lower-level, forward masking of the target by the cue … Black Hat Masking. If all of this domain forwarding with masking sounds a little bit shady to you, there is a reason. All domain forwarding and masking were once considered to be black hat SEO. At one time this was considered to be a deception and an attempt to manipulate visitors. The use of these methods was considered unethical. 2018-03-08 Forward and backward masking of contour by light was investigated with stimulus onset asynchronies from 20 to 180 ms in a group of 22 schizophrenic patients and 22 matched normal controls. Individuals with schizophrenia were selected using American Psychiatric Association (1987) criteria and were also assessed using the Andreasen scales for the presence of positive and negative symptoms (N.C forward masking, this later type reflecting a low level refractory period similar to that studied by VINCE (1948) and others. We will refer to this latter class of masking Type I forward masking.
The target might be invisible or appear to have reduced contrast or lightness. There are three different timing arrangements for masking: forward masking, backward masking, and simultaneous masking. In forward masking, the mask precedes the target. In backward masking the mask follows the target. In simultaneous masking, the
Masking is a term in perceptual experiments where a detectable stimulus (target stimulus) becomes undetectable by the presentation of a second stimulus (the masking stimulus) in close temporal or spatial proximity to it.

In backward masking the mask follows the target. In simultaneous masking, the mask and target are shown together. There are two different spatial arrangements for masking: pattern masking and metacontrast. Pattern masking occurs when the target and mask locations overlap. Masking is a process in which humans change or “mask” their natural personality to conform to social norms or conventional ‘expected’ behaviors.

Masking hides the URL that you are forwarding the visitor to. With a normal forwarding, the user sees the destination URL in the browser’s address bar once the redirect is completed. But with masking, the target domain is hidden from the user and the original domain is displayed, keeping the user unaware that he is redirected to some other site.
