Scientists at Toronto University in Canada say that symbols of fast food can incite individuals to become impatient, squander money, and crave instant gratification. From theTimes of London:
Participants in experiments became jittery even when shown the logo of the McDonald's burger chain on screen for such a short instant that they could not recognise it.
Although each individual sighting of a logo has only a short-term subliminal effect, researchers fear that walking daily past numerous burger bars and sandwich shops could have a cumulative "behavioural priming" effect, making people hurry whether or not they are pushed for time.
We're finding that the mere exposure to fast food is promoting a general sense of haste and impatience regardless of the context."
