It seems indeed that In other words, what we experience is but the tip of the iceberg: massive amounts of informationĪre processed, have an influence on our behaviour, all the while going unnoticed. The great mysteries that common knowledge has come to associate with psychology is the idea that much of what goes on in our Extensive testing by researchers has shown that these products have no therapeutic utility.Ever since the concept of the “unconscious” defragmented one of the last nuclei of certitude in the western world, one of For example, in the 1980s subliminal auditory tapes were advertised as being able to produce many desirable effects, including weight loss, memory enhancement, and improvement of sexual function. While some researchers have reported subliminal effects of a more profound nature than a mere priming effect, the claims are, at best, controversial and sometimes completely false. In fact, two-word subliminal primes do not appear to work. It does not show that people's motives, beliefs, or behavior can be significantly altered by secret messages. It is important to emphasize that subliminal priming is obtained under extraordinarily artificial conditions, and that the effect is very subtle and brief. Thus, there is a discrepancy between what is perceived and what the viewer is aware of having perceived. Would the priming effect still occur? The answer is yes, and this finding is interesting because it shows that the prime initiates cognitive activity in the brain, even though the viewer does not feel as if any word recognition took place. Researchers interested in subliminal perception wondered what would happen if the prime was presented so briefly that the viewer could not recognize it. This priming effect is a well-established phenomenon. Thus, people will identify the target string DOCTOR as a word more quickly if it is primed with NURSE than they would if it were primed with an unrelated word like TRUCK. Reaction times are faster when the target is preceded by a word whose meaning is similar to the target's meaning (e.g., NURSE). Of special interest is how long it takes the subject to make his or her decision. If it isn't a word (e.g., TORCOD), he pushes the "no" button. If the target is a legitimate word (e.g., DOCTOR), the respondent pushes the "yes" button. ![]() In a priming task, the viewer's task is to decide whether or not a presented letter string (the target) is a word or not. The best evidence for subliminal perception comes from studies on semantic priming. Careful laboratory research has explored the extent to which subliminal stimulation can affect our behavior. ![]()
