Scientists found that moderate (适度的) noise can make people more creative, The New York Times reported.
Scientists did tests on students. They divided them into four groups. They then asked the students to do certain tasks involving creative thinking. But each group did the task with different volumes (音量) of background noise. They found that students did best when working under moderate noise—70 decibels (分贝). This is about the same volume of background noise in a cafe. Students did worse in low noise (50 dB). This is the volume of a quiet room. They did the poorest when in a high-noise (85 dB) environment. This is the noise level in a factory.
Moderate noise can distract (分心) people just enough so that they think more creatively. "It helps you think outside the box," Raci Mehta, a lead researcher in the study, said to the Business Standard. On the one hand, working in a very quiet place can strengthen our focus. But it also stops
us from thinking abstractly (抽象).
"This is why if you are too focused on a problem and you can't solve it," said Mehta, "you leave it for some time and then come back to it and you'll get the solution."
However, the scientists said that when you need to do detailed things, like proofreading (校对) a paper, a quiet place is better than a noisy one.
It's not WASTE until it is WASTED!
With the World Environment Day coming, our school is now requiring every student to form a habit of sorting the waste. Here in our schoolyard we lay four different colors of rubbish bins for different kinds of rubbish. The red is for harmful waste; the blue is for waste that can be recycled; the green is for kitchen waste; the yellow is for other waste. The followings are some instructions for you. Glass: Empty bottles without caps can be recycled to make new glass bottles. Warning: Mirrors and light bulbs must not be included in the glass waste. Paper: Newspapers, magazines, boxes must be clean enough to be recycled. Warning: Paper tissues and wallpaper are not recyclable as paper and should be kept separately. PMD waste: Packaging made of Plastic or Metal and drink boxes are used to make new packaging. Warning: Plastic pots (e.g. yoghurt pots), plastic bags must not be included in the PMD waste. Harmful waste: out-of-date drugs, used batteries(电池), paint and oil … Besides, if you don't need your old bikes at all, our school volunteers will collect them. We're going to fix them up and then give them away to kids who don't have enough money for a bike. To find out more about recycling, you can visit our school website. | |
