Subliminal Message is a free application (available for mac and pc) that allows you to create and display custom subliminal messages while using your computer. Trying to quit smoking? Just add a custom message (“Cigarettes taste like the floor of a public bathroom”) and tweak the settings to determine the text size & color, how long the message appears on screen, and the period between flashes. The software comes with 90 built-in messages and also features a picture mode that allows you to display a jpg instead of text.
An interesting free application for anyone interested in experimenting with subliminals. Recent research suggests that the brain does perceive subliminal messages, though many question whether these messages influence behavior. I’m currently using the software with the message: “My mother-in-law is not evil incarnate”. Do subliminals work? Time will tell.
