One afternoon last week, I saw three tearful children from my son's school being comforted by teachers. That morning, my 11-year-old had stomach pains, retching(干呕)into a bowl. Talking to other mothers later, I heard about other children with stomachache or difficulty sleeping the night before.

What caused so much pain? Sports day. Sports day might be necessary at a highly-competitive independent school, but not at a village primary school. For the children who can fly like the wind, sports day causes no problem. For those who are overweight or just not good at sport, it is a nightmare(噩梦). Even for those who enjoy running but fall halfway down the track in front of the entire school and their parents, it can prove a disaster.

    Why do we put our children through this annual suffering? Some may say competition is character building; or it's taking part, not winning, that's important; or that it is a tradition of school life. I just felt great pity for those children in tears or in pain.

    Team games at the end of sports day produced some close races, wild enthusiasm, lots of shouting—and were fun to watch. More importantly, the children who were not so fast or quick at passing the ball were hidden a little from everyone's eyes. Some of them also had the thrill of being on the winning side.

    I wish that sports day could be abandoned and replaced with some other less-competitive event. Perhaps an afternoon of team games, with a few races for those who want them, would be less stressful for the children and a lot more fun to watch.

    A new study from the Georgia Institute of Technology finds that older and younger people have a varying preference for what they would want a personal robot to look like. And they change their minds based on what the robot is supposed to do.

    Participants were shown a series of photos, either robotic, human or mixed human-robot faces, and were asked to select the one that they would prefer for their robot's appearance. Most college-aged adults in the study preferred a robotic appearance, although the others were also generally open to them. However, nearly 60 percent of older adults said they would want a robot with a human face, and only 6 percent of them chose one with a mixed human-robot appearance.

    "We found that participants, both younger and older, will assign emotional traits to a robot based on its face, which will determine what they are most comfortably interacting with," Akanksha Prakash, a psychology graduate student at Georgia Tech who led the study, said in a statement. So when participants were told the robot was helping with personal care, chores, social interaction or helping to make decisions, something interesting happened.

    Preference was less strong for helping with chores, although the majority of older and younger participants chose a robot with a robotic face. But for decision-making tasks, such as getting advice on where to invest money, younger participants tended to select a mixed human-robot appearance. A robotic face was their least favored choice for this task. Older adults generally preferred a human face. Personal care tasks such as bathing caused the most divisive preferences within both age groups. Those who chose a human face did so because they associated the robot with human-like care capabilities — such as nursing — and trustworthy traits. Many others didn't want anything looking like a human to bathe them due to the private nature of the task.

    Based on this early research, the researcher says that if a robot is designed to help only with a specific task, its appearance should fit in with the task. For instance, if the robot is designed to specifically assist the user with critical decisions, the robot should be given an intelligent look instead of a funny one. However, if the robot is tasked with a variety of jobs in the home, allowing for appearance customizability(可定制性) might be the best option.

    The researcher next plans to expand the study to other age groups and people with more diverse educational backgrounds.

    A 12-year-old with end stage cancer, the child's parents had recently moved her from the hospital to her home in the suburbs of Los Angeles. Some days later the girl's breath quickened, and her father phoned the family's hospice nurse. Please come, he said.

    The nurse knew the visit would require more than four hours of her time: a two-hour drive in each direction, plus her time with the girl. Why don't we connect over FaceTime, she asked. The father agreed, and they connected.

The nurse asked the father to move his daughter gently to her side, then to her back, to lift the child's shirt. The nurse would ask: What do you see, what concerns you, and the father would explain. In this fashion the pair examined the girl — the nurse on her computer, the father his iPad. Together they decided that the nurse's presence was not necessary, that the child had more time.

    Later, the father reported feeling comforted by the nurse. He appreciated her availability, the fact that she could see what he saw, and their ability to discuss it in real time.

Telemedicine has become a trend in America. Some hospitals have gone so far as to specially design telemedicine clinics. The room is staged like an office but with better lighting. There's a nice desk for the clinician to sit behind, a computer situated stage left, and books in the background. A physician taking a video call from home might wear a pair of headphones, equipped with a mic — to ensure whatever the patient says isn't broadcast to anyone off-camera.

    However, there is something more than the technology bit. According to David, the head of the telemedicine pilot the girl's family had been part of, there are some people who are great in person and you put them on camera they're a dead fish. “Some physicians are camera shy. For others, the physical isolation can actually help them be more empathetic.” He adds.

    “My experience is that, once you get past some initial hurdles, you can maintain an intimate, immediate connection with patients that in some cases may be more useful than even in-person interactions,” David says.

We are interested in the preservation of the biodiversity on Earth. What I've been working on is rats. Just looking at rats, you can understand continental drift and climate change. We've actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn't exist? They wouldn't even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been: We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face— It looked like he'd seen a ghost.

I certainly understand the argument: "Who cares about an extinct rat?" but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that's why people love pandas and want to keep them around. You never hear, "What good is panda?" Ecologically, these rats are much more important to their ecosystem than those pandas— not that I don't love pandas but we have to look beyond the big and beautiful.

    I teach conservation biology and evolution. In both you have to appeal to people asking "Why is this important to me?" Some scientists refuse to do that. That's my entire approach. I'll ask "How many of you had a family member who was in a tornado, hurricane or flood?" .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

    An article describing the attitude of post-1990s generations toward life has recently gone viral on Chinese social media, which resonates with(引起共鸣) millions of youngsters for reflecting their casualness and calmness under gradually increasing social pressure.

    The article was first published on WeChat with the title of “The first group of post-90s generation who have become monks”. By using the phrase “Buddha-like youngsters”(佛系青年), it claimed that some of the post-90s generations, who were born between 1990 and 1992, have “seen through the emptiness of life” and kept a casual and calm attitude toward career and life.

    “It's fine to have something or not and there is no need to pursue or win anything," said the article, while defining "Buddha-like" people and clarifying that the phrase has nothing to do with the religion of Buddhism. An easy example is that Buddha-like youngsters do not care about taking which way to return home or choosing what to eat for lunch, according to the article.

    The phrase has touched the nerves of the Chinese youngsters who are facing the fast-paced life, cut-throat world of career and great mental pressure in China, read a commentary by People's Daily on Wednesday. The phrase was well received by Chinese netizens; the original WeChat post has been viewed by more than 1 million times and then read more than 60 million times on SinaWeibo by Wednesday.

    “The phrase properly describes the mentalities and lifestyle of (some of) the post-90s generations in China, who have become less ambitious and more casual toward life due to the great pressure and fierce competition in today's China”, one SinaWeibo user commented.

    Are you a Buddha-like youngster？

    Psychology has a new application in the field of medicine. Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals, modern therapy(疗法)seems to focus on the physical disease. Patients may feel they are treated like broken machines. Some doctors have recognized this as a problem. They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine. The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.

    The doctor knows that a disease affects a patient's body physically. The body of the patient changes because of the disease. He is not only physically affected, but also has an emotional response to the disease. Because his mind is affected, and his attitude and behavior change. The medical treatment might cure the patient's physical problems, but the patient's mind must fight the emotional ones. For example, the studies of one doctor, Carl Simonton, M.D., have shown that a typical cancer patient has predictable attitudes. She typically feels depressed, upset, and angry. Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses. Such attitudes and behaviors prevent recovery. Therefore, a doctor's treatment must help the patient change that. Simonton's method emphasizes treatment of the "whole" patient.

    The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive. The physician who is following Simonton's psychological treatment plan suggests that the patient imagine that he or she can see the tumor(肿瘤)in the body. In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hitting the tumor cells and causing them to shrink. For another cancer patient, Dr. Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carrying away the dead cells. Both the medical therapy and the patient's positive attitude fight the disease.

    Doctors are not certain why this mental therapy works. However, this use of psychology does help some patients because their attitudes about themselves change. They become more confident because they use the power within their own minds to help stop the disease.

    Another application of using the mind to help cure disease is the use of suggestion therapy. At first, the doctor helps the patient to concentrate deeply. The patient thinks only about one thing. He becomes so unaware of other things around him that he is asleep, or rather in a trance(催眠状态). Then the physician makes "a suggestion" to the patient about the medical problem. The patient's mind responds to the suggestion even after the patient is no longer in the trance. In this way, the patient uses his mind to help his body respond to treatment.

    Doctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with the strong pain of some disease. Furthermore, such treatment may help the patient with a chronic diseases. Suggestion has been used to change children's habits like nail­biting, thumb­sucking, and sleep­related problems.

    Many professional medical groups have accepted the medical use of psychology and that psychology has important applications in medicine.
