The Operational Potential of Subliminal Perception – 1958
Approved for release 1984 – CIA Historical Review Program 
Same Document – Page 65
– Individual perception without awareness of the stimulus
– Studied in laboratories for 70 years at the time (1958)
Example: An increase in popcorn sales in a New Jersey movie theater is said to have been stimulated by subliminal interruptions of the feature film with an advertisement urging the patrons to buy popcorn.
– Exposure time is a fraction of a second
– It has been demonstrated that certain individuals can at certain times and under certain circumstances be influenced to act abnormally without awareness of the influence.
– Danger of a “flashback” and unpredictable results.
– Four principle categories of behavior without awareness
a) An individual fails to realize his abnormal behavior because his normal awareness and self control have been interrupted by disturbing agents such as fear, anxiety, illness, drugs, or hypnotic suggestion.
b) Operant conditioning (also called “instrumental conditioning”) is a learning process through which the strength of a behavior is modified by reward or punishment.
