A study conducted by the University of Toronto has found that exposure to fast-food logos can cause people to feel impatient and make them more likely to buy things
. Subjects in the study were exposed to nearly imperceptible flashes of images (for 12 to 80 milliseconds) which included fast-food logos for some. The subjects were then asked to read about and choose between two different kinds of skin-care treatments, one of which was a three-in-one. Those who had the logos flashed before them read "significantly faster" and chose the more time-saving skin product. From the article: "The researchers concluded 'fast food, originally designed to save time, can have the unexpected consequence of inducing haste and impatience' and 'preference for time-saving products when there are potentially other important aspects upon which to choose a product.' So, basically, driving past a McDonald's on the highway has the potential to not only make you drive faster, it will make you more likely to buy two-for-one Pantene Pro-V Shampoo and Conditioner the next time you go to Duane Reade. One, it seems, is considerably less ominous than the other." I guess this explains why my nephews will chew on their seat belts and try to get out the windows just to be first into the McDonald's Playland.
