Subliminal Messages Might Actually Work
GrumpySimon writes "New research indicates that subliminal messages may actually work. In a paper titled Attentional Load Modulates Responses of Human Primary Visual Cortex to Invisible Stimuli, Bahrani et al. demonstrate that even though stimuli may not be available to consciousness, they are processed by the visual cortex. While I'm sure that marketing agencies all over the world are rubbing their hands in glee at this news, the authors report that there's no evidence that this can make people buy things against their will. So with any luck the use of subliminal messages in advertising will remain an urban legend."
This isn't exactly new information. It's been widely available for decades that yes, in fact, you do register subliminal messages. But it's also been proven time and again, that they have a statistically insignificant effect on your desires, and CERTAINLY not enough to change your opinions.
If I remember my college psych classes properly, subliminal messages to buy a product may work to some degree, but obvious ads to buy a product work far better. There's lots of studies on the effectiveness of advertising, and not very many on the effectiveness of subliminal messages.
I think Greenwald is the author I was thinking of, but some of these other articles may be useful.
