By Barry Fox A more effective way of embedding subliminal images in television programmes is being patented by Vitaliano Silingardi of Bologna (EP 995 458). The normal technique for transmitting a subliminal message—such as “smoking kills”—is to display it for a few milliseconds and then replace it with a blank white screen to stop the image from persisting on the retina. Silingardi’s trick is to first flash a trigger image—such as someone smoking—which prepares the brain for the subliminal message.
