Sorry, I didn't get the nineteenth term posted.
July 19th pick is Pareidolia
Pareidolia is a common psychological phenomenon in which random stimulus is organized by the brain into a recognizable pattern (e.g., seeing faces in wallpaper patterns, or hearing musical beats in the sound of heavy machinery). Often used synonymously with the term "matrixing," pareidolia explains a large percentage of visual evidence mistakenly touted as definitive proof of the paranormal. In photographic evidence, it occurs in the tendency to pick shapes out of the blurry background or the random contrasts of light and shade (the face in a window, for example, that's merely the window pane reflecting the trees). In audio evidence, it occurs largely in the tendency to hear words and phrases in random sound; a good example of this is in Class C EVPs where words and phrases are discerned in the white noise, but without consensus as to what they are saying. Critics of those who protest claims of pareidolia rightly point out the interpretive bias that often accompanies such evidence: an apparition in the rust of an oil tanker may resemble a veil and a blank face, but, predisposed to a religious interpretation, the observer will fill in the missing details and identify it as the face of the Virgin Mary; or, fear of "evil spirits" or concern for "lost souls" will influence the listener to hear "Get out!" or "Help me!" in the white noise of poorly recorded digital audio. Pareidolia can be a powerfully convincing experience and, as such, it is sometimes difficult to disabuse people of their assumptions once they take an emotional or psychological investment in them. Consequently, pareidolia is a challenging problem for paranormal investigators who value objectivity in their analysis of the evidence.
July 20th pick is White Noise
White noise is a random, neutral sound with a flat power spectral density. Most recording devices, analog or digital, generate a degree of white noise in their recordings, the sound of which is frequently compared to a rushing waterfall. In fact, white noise generators are used as meditative and sleep aids for this very reason, since white noise creates a calming and constant "background" sound that drowns out peripheral noises. Paranormal investigators fall into two camps of thought about its uses. One sees it as a substantial liability--a result of poorer quality microphones or inadequate controls on the baseline sound of the environment. Another, however, actively contrives it in the evidence with a belief that "spirits" harness white noise to facilitate EVP communication. Anything from specially designed white noise generators, to oscillating fans and coffee percolators, have been used to produce white noise with the express intention of culling EVP evidence. Critics of this technique, however, remain suspicious of the considerable opportunity for matrixing this creates, i.e., the human brain's tendency to impose ordered speech onto random sound. They also point out that little evidence relying on white noise ever surpasses a Class C EVP. This technique of generating white noise is by no means a new one, but it recently received a certain cache of credibility after the success of the film White Noise, which showcased electronic voice phenomena.
