What is a Subliminal Message?
Below “absolute threshold”› Smallest amount of a stimulus that a
person can detect
Examples: Sight: A candle flame at 30 miles
away Sound: A watch ticking 20 feet away
Definition of a Subliminal Message
Sights & sounds presented so briefly or faintly that we fail to perceive them.
Presented BELOW our absolute threshold of sensory awareness.
But can these feeble stimuli influence our behavior?

How Are They Supposed to Work?
Claim #1: your brain understands complex meanings of phrases presented at WEAK levels
Claim #2: Subliminal stimuli worm their way into your unconsciousness
Modern Psychology
Accepts that much of our mental processing goes on OUTSIDE our immediate awareness.
Serial vs. Parallel processing
Dual processing
Conscious & unconscious work together
Serial Processing (CONSCIOUS): controlled› Step by step (one completed, go to the next)› New chess players take one move at a time.
Parallel Processing (UNCONSCIOUS): automatic
› Processing many different stimuli simultaneously› Experienced chess players, planning moves in
advance
Color, Depth, Movement, Form

Parallel & Serial Processing
New experiences require MORE conscious attention
Behaviors can become automatic with practice.
What can you do without your conscious attention?
Normal Dissociation
Daydreaming
Getting “lost” in a good› Book› TV Show› Conversation
“Highway hypnosis”
Real vs. Pop Psychology
These examples are different from the “non-conscious” processing proposed by proponents.
Holdovers from Freudian view of the mind.
Freudian View
Unconscious:
Primitive, primarily sexual, urges
Operate outside of our awareness
Influences our behavior
View Popularized 1950’s
James Vicary
Subliminal advertising
“Drink Coca-Cola,” “Hungry? Eat Popcorn” flashed 1/3,000 of a second
Reported that sales increased
1962, Vicary admitted he lied
But the Idea Caught On…
Subliminal Seduction (1973)
Wilson Brian Key› Advertisers using sexual images
› Warned that single exposure could affect consumers 1 week later!
› No real evidence
Public Alarm
U.S. Federal Communications Commission (FCC)
› Found no evidence
› But declared it “contrary to public interest”
Canadian Broadcasting System
Nationwide test Viewers informed Subliminally flashed “phone now” (352
times during program) Phone usage did NOT increase A few called in to say they felt hungrier
and thirstier!! Still NO evidence!
Other Bizarre Claims
Backmasking
Judas Priest (heavy metal rock band)
Encouraged suicidal behavior or subvert morality of teens

Thursday› Myth #7 – Sleep and Dreams› New Seats
John Vokey & J. Don Read (1985)
Controlled test
Participants given subtle suggestions as to what they were going to hear, perceived nonexistent messages in backward messages.
What Does Research Tell Us?
Short-lived and modest subliminal effects
Experiment:› Flash “priming” words or pictures briefly › Observers unaware› Speed & accuracy increases when asked to
identify a later stimulus
Example (Merikle, 1992):
Present subject with word stem “gui_ _”
Ask her to form a complete word (“guide” and “guile” are options)
Subliminally flash “direct,” “lead,” “escort” , probability for “guide”
Flash “deceit,” “treachery,” & “duplicity”, for “guile”
