Subliminal messages on slot machines

CBC News is reporting that Ontario’s gambling regulator has removed almost 90 slot machines from use because they appear to show subliminal jackpot displays every time the game is played.

Information displayed very quickly, or within a sequence of other images (known as ‘masking’ in psychology), can be found to have a detectable effect on the brain and measurable mental processes, despite the fact that people may be unaware of seeing them.

For example, one study found that images of fearful faces displayed at a rapid rate changed activity in a brain area called the amygdala, despite the participants having no conscious experience of seeing the fearful expressions.

It is not clear how much this sort of thing actually changes anyone’s behaviour, although the practice is outlawed in many countries as being dishonest.
