Question

Our sense of smell, which we normally take for granted, is nowadays being increasingly used for purposes which might surprise us if we realized them.
One area in which smells are created to achieve particular results is marketing. For some time producers have taken advantage of our sense of smell with regard to household goods.
When pleasant smells are passed through a store’s air conditioning system, people tend to spend more time in the store and buy more. For example, the smell of chocolate is used in sweet stores, while the smell of leather and perfume are used in clothes stores.
In a test, people looked at the same types of shoes in two rooms—one filled with purified air, the other with a smell of mixed flowers. Eighty-four percent of the people preferred the shoes in the room with the smell of flowers. In fact, many said they would have paid up to US $ 10 more for a pair.
Smells also have other uses. Research has shown that certain smells can help to calm anxious people and increase their feeling of safety. Smells such as that of flowers and pine forests might therefore be used to relax patients in doctors’ and dentists’ waiting rooms, and to make the environment more pleasant and less stressful to them.
Some companies are experimenting with different smells to produce different efferent effects on their workers according to the time of day.
For example, early in the morning they might put the smell of lemon in the air conditioning system to wake people up. In the middle of the morning, when the atmosphere tends to become more tense, the smell of wood could be used to calm people down. Before lunchtime the smell of melting butter would encourage people to go to lunch on time. After lunch, when people often begin to lose attention, the smell of mint would increase their watchfulness.
While some of these uses of smells may e helpful and effective, not everyone would agree with their use to control customers in stores. It has been suggested by consumers’ organizations that one way to avoid this new subconscious（无意识）pressure to buy is to go shopping when people are less likely to be influenced by smells.
