Humans are able to unconsciously perceive certain stimuli in their surroundings and whose intensity may approach both our minimum sensory threshold as well as the absolute maximum, usually of brief duration. These are known as subliminal messages.

But, do they have any effect on our behaviour?

This is the primary question and to answer it the first study was carried out in the 1950s and is still being researched today. What we do know is that independently of their efficacy, such messages have been used a large extent in the advertising sector in the spite of being considered illicit. It is interesting that they can be found with a wide variety of products, films and even in drawings.
