Article (Journal): Subliminal Messages in Advertising (n.d.)

A form of subliminal messaging commonly believed to exist involves the insertion of “hidden” messages into movies and TV programs. The concept of “moving pictures” relies on persistence of vision to create the illusion of movement in a series of images projected at 23 to 30 frames per second; the popular theory of subliminal messages usually suggests that subliminal commands can be inserted into this sequence at the rate of perhaps 1 frame in 25 (or roughly 1 frame per second). The hidden command in a single frame will flash across the screen so quickly that it is not consciously perceived, but the command will supposedly appeal to the subconscious mind of the viewer, and thus have some measurable effect in terms of behavior.¹
