Subliminal messages - do they really work? Featured science projectScience project video

Abstract

This experiment was conducted to find out whether subliminal messages can be effectively used to influence the decisions that the person makes.

Hypothesis

Persons exposed to  subliminal messages will more likely respond accordingly to the information contained in the messages.

Scientific Terms

Subliminal messaging, conscious, subconscious

Background

Subliminal message

Subliminal messaging is the transmission of information that will normally be ignored by our conscious mind but is instead perceived by our subconscious mind. The message may be transmitted  in the form of audio, visual, video or text. It is thought that because the subliminal message goes directly to the subconscious mind without the conscious mind  analyzing it, it becomes more easily accepted.

It is also believed that the behavior of a person can be altered by the use of subliminal messaging. Advertisers on radio and television are believed to be using subliminal messaging to convey hidden messages to the public.

The effectiveness of subliminal messaging has never really been proven. There is also a ban in some countries against the use of subliminal messaging in advertising. However this ban does not typically cover the music and the film industries.
