There is some evidence of subliminal perception inthe auditory and tactile systems, but a discussion of these effects isbeyond the scope of this module. I should note at the outset that we will be restricting our discussionof subliminal presentations to those that are presented exclusively tothe visual system. Along the waywe will consider the generalizability and reliability of subliminalinfluences, whether cognitive scientists can accommodate subliminalperception in current theories about the mind, why the phenomenon ofsubliminal perception is even interesting to cognitive scientists, andwhether there are any marketing implications for subliminal perception.
We will introduce you tothe nuts and bolts of subliminal presentations by letting you try toreplicate two, purportedly reliable, subliminal effects. This researchstands in stark contrast to the failings of subliminal advertising, andin this module we will investigate the replicability, generalizability,and validity of some of these new findings. Or do they? Cognitive and socialpsychologists are now learning that stimuli presented subliminally cannot only be perceived, but can have a considerable influence over avariety of cognitive processes (possibly even behavior). In short,research on subliminal advertising suggests that subliminally presentedstimuli have little or no influence on our thoughts, attitudes,preferences, or behavior. Regardless of its truth of falsity, Vicary's report spurredwhat has now been over 30 years of research into the effectiveness of anew marketing tool: subliminal advertising.The resulting body of work,not surprisingly given its dubious origin, has produced far fromimpressive results and has led to the strong conclusion that subliminaladvertising cannot influence the type of laundry detergent you buy, thetype of underwear you wear, or the candidate you vote for. Vicary, however, was the first to report impressivebehavioral influences in a domain with tremendous money makingpotential.

The notion that stimuli presented outsideconscious awareness could influence cognition was not new - in 1884 Peirce and Jastrow reported that peoplecould perceive small differencesin pressure to the skin without conscious awareness of differentsensations. Yearslater, Vicary himself admitted this scam was simply an attempt to savehis dying advertising agency.
There was, however, one significant and oftenunknown problem with Vicary's study - it was all a hoax. This startling prophecy seemed to gain plausibility in the late1950's after James Vicary reported significant increases in Coke andpopcorn sales after flashing directives to "Drink Coke" and "EatPopcorn" during a movie.Īlthough Vicary never actually published thesefindings, his reports created a frenzy of consumer concern andgovernment legislation aimed at stopping these forms of seeminglyinsidious mind control. Background.In the prophetic novel 1984,George Orwell foretold of a future in which our thoughts,attitudes, and behaviors would be controlled almost entirely by themedia.
