eat popcorn!
Imagine the power of an advertiser who could put persuasive thoughts into your mind without your conscious awareness! This is the idea behind so-called "subliminal" advertising. According to some popular accounts, movie theaters can sneak frames into the move that flash, "eat popcorn," and the audience, supposedly unaware of having read this message, will comply and buy more popcorn. The idea is that the message is displayed for such a short period of time that the viewer does not have time to consciously process it, and so is therefore not consciously aware of having ever seen the message. According to proponents of this idea, the viewer will nonetheless process the message at some level below consciousness and thereby act upon it.

tachistoscope
[Etymology: Greek Tachistos, very rapid, fr. Tachys, rapid, + skopeo, to view]

- An apparatus that projects a series of images onto a screen at rapid speed to test visual perception, memory, and learning.
[The American Heritage Dictionary of the English Language, Fourth Edition]

- A tachistoscope is a device that displays (usually by projecting) an image for a specific amount of time. It can be used to increase recognition speed or to show something too fast to be consciously recognized. The actual tachistoscopes use a slide or transparency projector equipped with the mechanical shutter system typical of a camera. The slide is loaded, the shutter locked open, and focusing and alignment are adjusted, then the shutter is closed. When ready for the test, a shutter speed is selected, and the shutter is tripped normally.
