Subliminal Messages Motivate People To Actually Do Things They Already Wanted To Do

How is it possible that you were not planning on going shopping, but that you still end up going and even return home with four new shirts? Apparently you really did want to go shopping but were not consciously aware of it. Researchers have demonstrated that you can motivate people with subliminal messaging: quickly flashing words onto a screen without their noticing. This is only successful, however, if the subliminal message matches a biological need and if the behavior is associated with a positive effect.
