Hacking our senses to boost learning power

Some schools are pumping music, noises and pleasant smells into the classroom to see if it improves exam results. Could it work? Why do songs stick in our heads? What does your school smell like? Is it noisy or peaceful?

It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity. Indeed, some head teachers have recently taken to broadcasting noises and pumping smells into their schools to see whether it can boost grades. Is there anything in it? And if so, what are the implications for the way we work and study?

There is certainly some well-established research to suggest that some noises can have a harmful effect on learning. Numerous studies over the past 15 years have found that children attending schools under the flight paths of large airports fall behind in their exam results. Bridget Shield, a professor of acoustics (声学) at London South Bank University, and Julie Dockrell, from the Institute of Education, have been conducting studies on the effects of all sorts of noises, such as traffic and sirens (汽笛), as well as noise generated by the children themselves. When they recreated those particular sounds in an experimental setting while children completed various learning tasks, they found a significant negative effect on exam scores. “Everything points to a bad impact of the noise on children’s performance, in numeracy, in literacy, and in spelling,” says Shield. The noise seemed to have an especially harmful effect on children with special needs.

Whether background sounds are beneficial or not seems to depend on what kind of noise it is — and the volume. In a series of studies published last year, Ravi Mehta from the College of Business at Illinois and his colleagues tested people’s creativity while exposed to a soundtrack made up of background noises — such as coffee-shop chatter and construction-site drilling — at different volumes. They found that people were more creative when the background noises were played at a medium level than when volume was low. Loud background noise, however, damaged their creativity.

Many teachers all over the world already play music to students in class. Many are inspired by the belief that hearing music can boost IQ in later tasks, the so-called Mozart effect. While the evidence actually suggests it’s hard to say classical music boosts brainpower, researchers do think pleasant sounds before a task can sometimes lift your mood and help you perform well, says Perham, who has done his own studies on the phenomenon. The key appears to be that you enjoy what you’re hearing. “If you like the music or you like the sound — even listening to a Stephen King novel — then you do better. It doesn’t matter about the music,” he says.

So, it seems that schools that choose to prevent disturbing noises and create positive soundscapes could enhance the learning of their students, so long as they make careful choices. Yet this isn’t the only sense being used to affect learning. Special educational needs students at Sydenham high school in London are being encouraged to revise different subjects in the presence of different smells — grapefruit scents for maths, lavender for French and spearmint for history.

All it took was a slice of Xinjiang cake to spark heated debates online over China's policy on ethnic minorities (少数民族) .

Since Monday, qiegao (cut cake) has been a trending topic on Sina Weibo, China’s main Twitter-like microblogging service.

The cake was a reference to Xinjiang’s famed nut cake, sometimes known by its old Turkic name baklava, a popular pastry across Central Asia and the Middle East. In Xinjiang, they are sold by Uygur vendors on tricycles who are known to charge dubious prices depending on the time and season.

The ethnic flare-up started after the Yueyang police from Hunan province posted a message on their official Weibo account. It reported a dispute in Pingjiang county over an overpriced piece of nut cake between a Xinjiang Uygur vendor and a villager named "Ling".

Villager Ling got into a fight with a Uygur due to a misunderstanding. The verbal dispute eventually escalated into a fight and then a mass fight. As a result, two people were injured and Xinjiang nut cakes worth about 160,000 yuan (US$25,000) were destroyed. The total damage was worth 200,000 yuan which included a broken motorcycle and injuries to people. Local police have detained Ling. The 16 Uygur sellers were dully compensated and sent back to Xinjiang.

"Yueyang police incident" quickly became one of the most popular topics on Weibo. Yueyang police removed the post shortly after. As of Tuesday night, the topic was still amassing more than 66,000 hits.

The incident is just one of many similar cases of ethnic tensions across China, notably in Xinjiang province, where deeply entrenched social and racial frictions between the dominant ethnic Han Chinese and minority Uygur Muslims occasionally spark violence. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists.

1.Which of the following is true?

A. The dispute is between a Xinjiang Uygur vendor and a policeman.

B. Nut cake is a popular pastry across East Asia and the Middle East.

C. The prices of Baklava will change according to the time and season.

D. The demand of the 16 Uygur sellers were refused and they were sent back to Xinjiang.

2.How much did the broken motorcycle cost？

A. 160,000 yuan B. 200,000 yuan C. 40,000yuan D. We don’t know

3.What’s the best title of the passage?

A. World's most expensive baklava

B. Ethnic tensions across China

C. Pay attention to the Uygurs

D. Misunderstanding caused a fight

4.What can we infer from the passage?

A. Yueyang police are afraid of the Xinjiang Uygur vendor

B. It’s not the only ethnic tension across China,

C. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists.

D. Villager Ling got into a fight with a Uygur due to a misunderstanding.

Zebras have their own bug repellent(驱虫剂)?

Eww bugs! They are so annoying! We humans are lucky that we can apply repellents to avoid nasty bites. But what’s an animal to do? They have no choice but to spend their days shooing them off with their tails, unless, of course, they are zebras, who apparently have their own automatic repellent--- their striped skin!

Scientists had originally thought that the reason why the animal had developed the black and white lines was to help protect itself from predators in the African savannah, because the stripes make it difficult to single out one zebra that is traveling with a herd.While that may be true, the theory has never been tested or proven. Now the experts have another---that the stripes have evolved to repel the annoying horse flies that not only feed off their blood, but also, transmit dangerous germs into the bodies of these innocent animals.

The study was performed by a team of Swedish scientists. One of the clues that got them thinking along these lines was the fact that darker horses got bitten more often than light-colored or white ones.

The fact that zebras are born black and only develop strips as they grow older made the scientists theorize that the stripes may be something the animals have developed to make themselves less attractive to flies.

To test if this may be the case, they painted some boards at a horse-infested horse farm in Budapest with patterns of black and white stripes of varying widths and applied a layer of glue on them. What they noticed was that the places where the black and white stripes were at their narrowest (similar to what zebras have) attracted the fewest flies. They achieved similar results when they painted horses with black and white zebra-like stripes.

While the research are not sure why this may be the case, they believe it may be something to do with the way insects operate---horseflies are attracted to horizontally polarized light（偏振光）; since white does not reflect it, white horses are luckier than black ones. But zebras seem to be the luckiest of all. When the researchers measured the polarized light reflected from real zebra skins, they found that it matched light patterns that were the least attractive to horseflies.

While this theory does make logical sense, nobody is 100 percent sure that it is really true, given that it has never been tested on a real zebra. If it is true, it does raise the question of why a horse, a close relative of the zebra has failed to develop stripes. The researchers believe that this could be because there are more horseflies in Africa, where zebras reside, then anywhere else in the world.
