The accepted history of data processing without consciousness, also called masked or shadow information and even referred to as peripheral information, but more commonly known by the general public under one universal label as subliminal sessions, is really just a history of contemporary manoeuvring.
Vance Packard's, Hidden Persuaders, appeared in 1957. It quotes the New Jersey Sunday Times an account of a theater in which ice cream ads were being flashed on the silver screen during movie showing. That trick apparently resulted in an otherwise inexplicable swelling in ice cream sales. The New Jersey Times referred to this technology then as "subthreshold effects", nowadays its subliminal sessions.
Packard's book warned psychologists who turned merchandisers and the resulting psychoseduction of American consumers. From systems of faith to product recognition, Packard presented a case for influence through art and science of motivational analysis, feedback, and psychological manipulation. The book was the first effort to tell the public of a potentially Big Brother means to bind the mind and to do so covertly.
In his 1974 book Subliminal Seduction, Wilson Brian Key argues that not only is the people being subjected to subliminal sessions and merchandised today but the public has been seduced for the longest time. Wilson Key, a Canadian university professor, sums it all up in the title to a third book on the subject, Media Sexploitation, 1977.
In the, Subliminal Communication, 1990 it was discussed that the earliest modern reference found on the subject of subliminal sessions. Suslowa reported in 1973 an increase in the two-point discrimination threshold as a function of subliminal electrical stimulation. In 1894 W. R. Dunham, M.D. wrote an attention-grabbing remark on the subliminal mind, subliminal communication and subliminal sessions. Nearly one hundred years later, W.R. Dunham's amazing essay reads much like contemporary research on the subject. In The Science of the Vital Force, W.R. Dunham showed the existence of both the subliminal mind and subliminal sessions in communication.
One of Sigmund Freud's most significant work to approaching the mystery known as the human condition is the revelation that the human race is a mere particle of his potential. Unconscious processes determine conscious choices and therefore by extension behavior. The aggregates of attitude and behavior constitute a person's personality. The personality to a certain extent is rather rigid, and as a result the human condition is a terrible silhouette of itself. What is more, according to Sigmund Freud, it is inherently in conflict with itself.
The peripheral insight, shadowed or masked information, all under the genre of subliminal sessions, is one of the most powerful techniques presently available. It can literally reprogram the preconscious mind, by stripping away all the negative expectations and self-doubt, and replacing these unhelpful patterns with positive input, thus bringing about optimistic changes in an easy and natural way from the inside out.
There is nothing strange or outstanding about all of this. Yet, part of the difficulty in understanding subliminal sessions rests in the word itself. A subliminal message, at least in the instance of an audio device, could be distinct as a spoken stimulus perceived below the level of awareness. Now, the key word here is awareness.
