Nathan Janes, PUPAGANDA.com: Many people may not realize that when they turn on the television in their home, what they see as a constant flow of images is actually flickering. Although we do not see this consciously, the repetitive pattern of flickering images creates a state that is similar to hypnosis in the television viewer.
Studies by researcher Herbert Krugman have shown that within 30 seconds of television viewing, brain waves switch from predominantly beta waves, indicating alert and conscious attention, to predominantly alpha waves, indicating an unfocused, receptive lack of attention. The brain’s left hemisphere, which processes information logically and analytically, tunes out while the person is watching TV, while the right hemisphere of the brain, which processes information emotionally and non-critically, is allowed to function without hindrance.
Due to this phenomenon, television transmits information, which is not actively thought about at the time of exposure, much like hypnosis. When viewing television, we do not consciously rationalize the information resonating within our unconscious depths at the time of transmission and the viewer becomes more open and suggestible.
