The wider implication for the study, published in Current Biology, is that techniques such as subliminal advertising, now banned in the UK but still legal in the USA, certainly do leave their mark on the brain. University College London researchers have found the first physiological evidence that invisible subliminal images do attract the brain's attention on a subconscious level. One East Coast chain amounted savings of 600,000 over a nine-month period.Īnother story in the Wall Street Journal in 1980 stated that subliminal messaging a New Orleans supermarket resulted in an all time low within 6 months of use - from 50,000 per six month period to a figure of 13,000! Furthermore cashier shortages dropped from 125 per week to below 10 per week. and Canada had been using subliminal messages over their music systems which had resulted in a significant reduction in both customer based shoplifting and employee theft. In 1979 that nearly 50 department stores in the U.S. The following sections have more information on specific studies in which the effectiveness of subliminal stimuli are investigated.Īn article with several links to research on the topic: Importantly, research on action priming has shown that subliminal stimuli can trigger only those actions that one plans to perform anyway: an action can be triggered subliminally only if the person already has the specific intention to perform this specific action. Applications, however, often base themselves on the persuasiveness of the message. The effectiveness in subliminal messaging has been demonstrated to prime individual responses and stimulate mild emotional activity. I take it you mean to send a subliminal command and make someone obey that command.īased on that definition, here's some of what I find from googling:

PDF Available FREE from National Chiao Tung University A meta-analysis of consumer choice and subliminal advertising, Psychology & Marketing, 13(5): pp. Of course, one has to consider if subliminal perception is qualitatively and quantitatively different depending on the modality of the stimuli but then again I am unconvinced of a considerable effect of subliminal messaging on behaviour. Also, what I get from most psychology textbooks is that the general consensus is that subliminal messaging has a poor and temporary effect (Schacter, Gilbert and Wegner, 2009). On the other hand, studies by Vockey and Read (1985) challenged the effect of subliminal messages in songs and a meta-analysis carried out by Charles Trappey (1996) showed a negligible effect on consumer behavior.
Other than null results or junk science I haven't seen any convincing study supporting these claims. My question is about certain big claims like those of Bryan Wilson Key on subliminal messages with sexual content and consumer behaviour, those about subliminal self-help tapes or those even more suspicious that are about subliminal messages detering shoplifters to steal.
I certainly don't question the existence of subliminal perception which has been demonstrated many times in priming studies like those of Daniel Schacter and many others, nor do I reject the notion of the cognitive unconscious introduced by Kihlstrom (I definitely have my doubts on the psychodynamic unconscious however).
