研究表明,只是闻闻咖啡香就能提高数学能力
It's known to make you feel more awake, and now it seems that coffee may also improve your maths skills. And the best news is that you don't even need to drink it to see the improvements - you just need to smell it. Coffee is actually very healthy. It is loaded with antioxidants and beneficial nutrients that can improve your health. The studies show that coffee drinkers have a much lower risk of several serious diseases. A new study by researchers from Stevens Institute of Technology has revealed that the scent of coffee may help your maths skills. Professor Adriana Madzharov, who led the study, said: "It's not just that the coffee-like scent helped people perform better on analytical tasks, which was already interesting. But they also thought they would do better, and we demonstrated that this expectation was at least partly responsible for their improved performance." In the study, 100 business students took a 10-question algebra test. Half the group took the test in the presence of a coffee-like scent, while the other half took the test in an unscented room. The results revealed that the group in the coffee-smelling room scored significantly higher on the test than those in the unscented room. In a follow-up study, the researchers quizzed 200 new participants on their beliefs about various scents and their effects on human performance. Their answers revealed that they believed they would feel more alert in the presence of a coffee scent. This suggests that their expectations about performance may have influenced their improved skills. The researchers believe that the findings could have major implications in the real world. Professor Madzharov added: "Olfaction is one of our most powerful senses. Employers, architects, building developers, retail space managers and others, can use subtle scents to help shape employees' or occupants' experience with their environment. It's an area of great interest and potential." |
