On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk , Strayer explained that all this time spent with technology is making our brains tired.
Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain,which, Strayer explains, is important for critical thinking, problem-solving and decision-making.
So, it is important to give the brain a rest. And being in nature , Strayer claims , helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore , swim, sleep, eat and play. Camping may be just what a tired brain needs.
Take Carl for example.He lives in West Virginia and enjoys camping . He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children . She calls it a “regenerative” experience.
At the University of Utah , David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found , it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

【推荐3】New research suggests that there are only four basic facial expressions of emotion. However, how these expressions are understood might depend on where you are from.
Research by scientists from the University of Glasgow in the UK has challenged the traditional view of how the face expresses emotions. Many scientists had believed that there were six basic emotions that people from all cultures recognized. These were happiness, sadness, fear, anger, surprise and disgust(厌恶). However, the University of Glasgow’s work now suggests that the human face only had four basic expressions of emotions. This is because some pairs of emotions are impossible to tell apart, especially when they are first shown on the face. Fear and surprise, both share wide-open eyes. The facial expressions for anger and disgust also look the same.
So if our faces are only able to express four basic emotions, how do we communicate much more complex feelings? The study found that the way expressions are understood is different in different cultures. Lead researcher Rachael Jack was studying this because “facial expressions were considered to be universal”, she explained. However, while looking at how people from the East and West recognize different parts of the face, they found that although there are some common features across cultures, the six basic facial expressions of emotion are not recognized universally.
“We said we don’t know what a disgust face looks like in China, so the best way to go about that is to make all combinations of facial movements and show the Chinese people and ask them to choose the ones they think are disgust faces.” With the software they developed, they discovered that in the early stages of signaling emotion, fear and surprise, and anger and disgust, were often confused. Jack explained that this development of facial expressions is related to biology and social situations.
What has caught people’s interest is the cross-cultural aspect of the work. “This study shows which emotions we share, and which are different in different cultures,” Jack said. This finding could help us develop new communication technologies, for example ones that use video-calling programs like Skype. When you talk to someone in Japan in the future, a programme could “read” your facial expressions and then “translate” them for the Japanese person. The Japanese person would see the Japanese facial expression on their screen. In this way, people from different cultures could understand each other better.

【推荐1】Today, there are numerous ways to exercise and stay healthy. From working out in a gym to riding a bike to work, staying active may have never been easier. Despite all this, a new study finds Americans are actually much less active than their ancestors 200 years ago. In fact, researchers from Harvard University say the average American stays physically active for 30 fewer minutes than people did in 1820.
The team came to this conclusion after examining historical data which shows that body temperature among Americans has been falling for years. The results of a Stanford University report showed that the average body temperature of Americans has dropped from the age-old 98. 6 degrees Fahrenheit to about 97. 5 degrees.
They also looked at changes in metabolic rates (代谢率), which measure how physically active people are. Researchers found that the resting metabolic rate-the total number of calories the body burns while completely at rest-has declined by six percent since 1820. Researchers say metabolism plays a key role in producing bod heat and much of this depends on how active a person is.
So what’s the cause of all this? “Instead of walking to work, we take cars or trains; instead of physical labor in factories, we use machines,” says lead author Andrew K. Yegian. “We’ve made technology do our physical activity for us. Our hope is that this helps people think more about the long-term changes of activity that have come with our changes in lifestyle and technology.”
The team also pulled data from two other studies to come up with an estimate of how much exercise Americans got in 1820 in comparison to today. “This will bring great benefits to my field of work because it can help us assess just how much increases in the incidence (发生率) of heart disease and Alzheimer’s (老年痴呆症) is related to decreases in physical activity,” says Daniel E. Lieberman.

【推荐2】If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple --- eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.
During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.
The reason is thought to be the so–called similarity attraction theory --- where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food’s role in earning trust.
In a test, participants were told to watch TV --- where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.
The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”
Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”
