Negative images key to most effective subliminal messaging

Washington, September 28 (ANI): Negative messages make for the most effective subliminal messaging, according to new research funded by the Wellcome Trust.

A report on the study describes subliminal images as those shown so briefly that the viewer does not consciously ’see’ them.

Such images have long been the subject of controversy, particularly in the area of advertising.

Studies conducted in the past have already hinted that people can unconsciously pick up on subliminal information intended to provoke an emotional response, but limitations in the design of the studies have meant that the conclusions were ambiguous.

In the latest study, a UCL team led by Professor Nilli Lavie have found evidence that people are able to process emotional information from subliminal images.

The researchers have demonstrated conclusively that even under such conditions, information of negative value is better detected than information of positive value.

During the study, Lavie’s team showed fifty participants a series of words on a computer screen. Each word appeared on-screen for only a fraction of second - at times only a fiftieth of a second, much too fast for the participants to consciously read the word.

The researchers have revealed that the words were either positive (e.g. cheerful, flower and peace), negative (e.g. agony, despair and murder) or neutral (e.g. box, ear or kettle).

After each word, participants were asked to choose whether the word was neutral or ‘emotional’ (i.e. positive or negative), and how confident they were of their decision.

It was observed that the participants answered most accurately when responding to negative words - even when they believed they were merely guessing the answer.

“There has been much speculation about whether people can process emotional information unconsciously, for example pictures, faces and words. We have shown that people can perceive the emotional value of subliminal messages and have demonstrated conclusively that people are much more attuned to negative words,” says Lavie.

“Clearly, there are evolutionary advantages to responding rapidly to emotional information. We can’t wait for our consciousness to kick in if we see someone running towards us with a knife or if we drive under rainy or foggy weather conditions and see a sign warning ‘danger’,” the researcher adds.

Lavie believes that her team’s findings may have implications for the use of subliminal marketing to convey messages, both for advertising and public service announcements such as safety campaigns.

“Negative words may have more of a rapid impact. ‘Kill your speed’ should be more noticeable than ‘Slow down’. More controversially, highlighting a competitor’s negative qualities may work on a subliminal level much more effectively than shouting about your own selling points,” she says.
