Subliminal stimuli ( /sʌbˈlɪmɨnəl/; literally "below threshold"), contrary to supraliminal stimuli or "above threshold", are any sensory stimuli below an individual's threshold for conscious perception. Some research has found that subliminal messages do not produce strong or lasting changes in behavior. However, a recent review of functional magnetic resonance imaging (fMRI) studies shows that subliminal stimuli activate specific regions of the brain despite participants being unaware. Visual stimuli may be quickly flashed before an individual can process them, or flashed and then masked, thereby interrupting the processing. Audio stimuli may be played below audible volumes, masked by other stimuli, or recorded backwards in a process called backmasking.

Some articles on subliminal stimuli:
... a deficit in the late stages of conscious perception, but subliminal processing of the masked stimuli is preserved ... people who do not have the disease were primed with Arabic digit stimuli, followed by a mask that occurred at different, varying intervals ... longer threshold delay between the digit and conscious perception of the mask, but the subliminal priming of masked numbers was effective and had the same effects for both groups ...
Famous quotes containing the word stimuli:
“Unable to create a meaningful life for itself, the personality takes its own revenge: from the lower depths comes a regressive form of spontaneity: raw animality forms a counterpoise to the meaningless stimuli and the vicarious life to which the ordinary man is conditioned. Getting spiritual nourishment from this chaos of events, sensations, and devious interpretations is the equivalent of trying to pick through a garbage pile for food.”
—Lewis Mumford (18951990)
