1 . On a rainy afternoon in Aspinwall, Pennsylvania, a group of amateur musicians gathered to lay down a few tracks. This wasn’t the first time the band had performed together, but it was their first time in a recording studio.

The band, which calls itself Infinity, first performed its work at the 2022 Pittsburgh Schizophrenia Conference in November. All four band members are diagnosed with schizophrenia, a mental disorder that can cause people to interpret reality in abnormal ways, which can cause many kinds of disordered thinking.

Infinity formed five years ago when Flavio Chamis, a Brazilian composer and conductor, began working with the University of Pittsburgh Medical Center (UPMC) on how to use music to treat mental illness.

“Having a mental health diagnosis is not a reason to not have a creative life,” Chamis said. Schizophrenia can be disabling, but therapy, medication and even playing music can help, according to a growing body of research.

Chamis and K.N. Roy Chengappa, a professor of psychiatry (精神病学) at UPMC Western Psychiatric Hospital and the director of Pittsburgh’s schizophrenia conference, are continuing their efforts with the four musicians and to further investigate musical interventions in mental health outcomes.

As imaging techniques advance, scientists are working to answer precisely why music affects the brain in the ways that it does. Playing music seems to have an impact on timing systems in the brain, which are affected by major depression, schizophrenia and other illnesses. There is research indicating that training patients to play in rhythm can in fact help retrain the brain in other, less obvious ways. Interventions tend to have positive effects, but the research is still in early stages.

The band doesn’t have much formal music training, but they played and sang with touching sincerity. “It’s not supposed to be professional or perfect,” Chengappa said. “One of them has been my patient for 20 years. ... They’ve really blossomed.”

Chamis led the Infinity recording from the piano, with each musician in a separate sound-proof room listening to one another on headphones. The conductor and composer encouraged the musicians and gave advice after each take.

“It’s been great working on this with Flavio,” said guitarist David Baird. “I loved feeling like a professional. ... I want more.”

2 . Maps, number lines, shapes, artwork and other materials tend to cover elementary classroom walls. However, too much of a good thing may end up _______ attention and learning in young children, according to research published in Psychological Science.

Psychology researchers Anna V. Fisher, Karrie E. Godwin and Howard Seltman of Carnegie Mellon University looked at whether classroom displays affected children’s ability to maintain _______ during instruction and to learn the lesson content. They found that children in highly decorated classrooms were more distracted, spent more time off-task and demonstrated smaller learning _______than when the decorations were removed.

“Young children spend a lot of time — usually the whole day — in the same classroom, and we have shown that a classroom’s _______ environment can affect how much children learn,” said Fisher, lead author and associate professor of psychology in the Dietrich College of Humanities and Social Sciences.

Should teachers _______ their visual displays based on the findings of this study?

“We do not suggest by any means that this is the answer to all _______ problems. Furthermore,_______ research is needed to know what effect the classroom visual environment has on children’s attention and learning in real classrooms,” Fisher said. “_______, I would suggest that instead of removing all decorations, teachers should consider whether some of their visual displays do make it difficult for young children to _______.”

For the study, 24 kindergarten students were placed in ________classrooms for six introductory science lessons on topics they were unfamiliar with. Three lessons were taught in a heavily decorated classroom, and three lessons were given in a sparse (稀疏的) classroom. The results showed that while children learned in both __________ types, they learned more when the room was not heavily decorated. Specifically, children’s __________ on the test questions was higher in the sparse classroom (55% correct) than in the decorated classroom (42% correct).

“We were also interested in finding out if the visual displays were removed, whether the children’s attention would __________ to another distraction, such as talking to their peers, or the total amount of time they were distracted would remain the same,” said Godwin, a Ph.D. candidate in psychology and fellow of the Program in Interdisciplinary Education Research.

However, when the researchers totaled all of the time children spent off-task in both types of classrooms, the rate of off-task __________ was higher in the decorated classroom (38.6% time spent off-task) than in the sparse classroom (28.4% time spent off-task).

The researchers hope these findings will lead to further studies into developing guidelines to help teachers design classrooms __________.

Exercise Can Help Prevent Depression, Study Finds

How often do you exercise? A new     1     from researchers at the University of Cambridge shows that those who exercise are less likely to develop depression, even if they exercise less than the recommended amount.

The Department of Health and Human Services recommends that adults engage in 2.5 to 5 hours of moderate activity per week or one hour and 15 minutes to 2.5 hours of     2     aerobic (有氧的) exercise per week or some combination of the two.

Adults who took a walk for what     3     to 2.5 hours per week were less likely to develop depression than those who didn’t exercise at all, the study found. But even those who exercised less felt better than those who didn’t exercise at all, according to researchers. “In this study, a relatively small amount of physical activity were associated with a(n)     4     decrease in risks of depression,” the study says. The researchers analyzed 15 studies with nearly 200,000 participants. Those who did about half the recommended amount of physical activity per week had an 18% lower risk of depression     5     with adults who did not exercise, the study says. Participants who exercised the recommended amount had a 25% lower risk of depression than those who did not. Exercising more than the recommended amount hardly     6     depression risk, according to researchers.

Many     7     of exercise can lead to improved mental health. For example, working out can increase circulation (血液循环) to the brain and     8     the central nervous system, leading to what many refer to as a “runners high,” the study says. More exercise can also lead to improved physical health and a better body     9    , which can cause a person to be more social, researchers say.

Nearly 5% of adults in the U.S. report regular feelings of depression, according to the Centers for Disease Control and Prevention. Among the study participants, researchers estimate that 1 in every 9 cases of depression might have been prevented had everyone met recommended exercise     10    , the study says.

Why Ear-worms Get Stuck in Your Head

We all get a sensation when a song, for no apparent reason, refuses to leave your head — in fact we’re no strangers to the dreaded “ear-worm.” But a new study published in Psychology of Aesthetics, Creativity and the Arts reveals a fascinating insight into ear-worms, and why some songs are better than others in sticking in our heads by investigating the actual elements of the song that make it catchy in the first place.

To do this, most frequent ear-worms of the participants were entered into a database and compared to songs that had never been reported as an ear-worm at all. The melodic features of the tunes were then analyzed, revealing that ear-worm tunes were typically those songs that have overall melodic shapes common in Western pop music. A classic example of a common contour (音调的升降曲线) pattern is heard in Twinkle, Twinkle Little Star, where the first phrase rises in pitch and the second falls. This makes the tune easy to remember and has been exploited in many other nursery rhymes, but also in pop music.

In addition to the melodic shape, the other ingredient to the ear-worm formula is the unusual interval structure. The aim of this is to surpass the listener’s expectations of an average pop song, showing unexpected leaps or more repeated notes than usual. “Our findings show that you can, to some extent, predict which songs are going to get stuck in people’s heads based on the song’s melodic content,” says one of the researchers, “This could help song-writers or advertisers write a jingle (短歌) everyone will remember for days or months afterwards.”

The authors conclude that studies of ear-worms can help explain how the brain works, and improve our understanding in how perception, emotions, memory and spontaneous thoughts behave in different people.

7 . Pricing is managers’ biggest marketing headache. It’s where they feel the most pressure to perform and the least certain that they are doing a good job. All successful pricing efforts share two qualities: The policy combines well with the company’s overall marketing strategy, and the process is well-organized as a whole.

A company’s pricing policy sends a message to the market—it gives customers an important sense of a company’s philosophy. Consider Saturn Corporation (a wholly owned company of General Motors). Saturn wants to let consumers know that it is friendly and easy to do business with. Part of this concept is conveyed through initiatives such as inviting customers to the factory to see where the cars are made and sponsoring evenings at the dealership that combine a social event with training on car maintenance. But Saturn’s pricing policy sends a strong message as well. Can a friendly, trusting relationship be established with customers if a salesperson uses all the negotiating tricks in the book to try to separate them from that last $100? Of course not. Saturn has a “no hassle, no haggle” policy which removes the possibility of conflicts between dealer and potential customer. Customers have an easier time buying a car knowing that the next person in the door won’t negotiate a better deal.

Of course, there are typically many participants in the pricing process: Accounting provides cost estimates; marketing communicates the pricing strategy; sales provides specific customer input; production sets supply boundaries; and finance establishes the requirements for the entire company’s financial health. Input from diverse sources is necessary. However, problems arise when the philosophy of wide participation is carried over to the price-setting process without strong coordinating mechanisms (协调机制). For example, if the marketing department sets list prices, the salespeople negotiate discounts in the field, the legal department adjusts prices if necessary to prevent breaking the laws or contractual agreements, and the people filling orders negotiate price adjustments for delays in shipment, everybody’s best intentions usually end up bringing about less than the best results. In fact, the company may actually lose money on some orders.

9 . In the middle of 2023, a study conducted by the HuthLab at the University of Texas sent shockwaves through the fields of neuroscience (神经科学) and technology. For the first time, the thoughts and impressions of people _______ to communicate with the outside world were translated into continuous natural language, using a combination of artificial intelligence (AI) and brain imaging technology. This is the closest science has yet come to _______ someone’s mind.

Losing the ability to communicate is a deep cut to one’s sense of self. _______ this ability gives the patient greater control over their lives. But it could also give other entities, such as corporations, researchers and other third parties, a(n) _______ degree of insight into, or even control over, the lives of patients. The NeuroRights Foundation, based at Columbia University in New York, argues that new rights surrounding neurotechnologies will be _______ for all humans to preserve their privacy, identity, and free will. The potential _______ of disabled patients makes this a particularly important problem.

_______ this approach, Chile was the first country that adopted legislation, drafting new laws, to address the risks of neurotechnology. It not only introduced a new constitutional right to mental _______, but is also in the process of adopting a bill that bans selling neurodata, and forces all neurotech devices to be regulated as medical devices, even those intended for the general consumer.

The proposed legislation recognizes the intensely _______ nature of neural data and considers it as organ tissues, which cannot be bought or sold, only donated. But this legislation has also faced ________, with legal scholars questioning the need for new rights and pointing out that it could discourage beneficial brain research for disabled patients.

While the legal action taken by Chile is the most impactful and ________ to date, other countries are considering updating existing laws to face the new developments in neurotechnologies.

And while it is likely that the first applications of neurotech will be medical, future ________ are likely to involve consumer applications such as entertainment, as well as for military and security purposes. The growing ________ of neurotechnology in a commercial context only causes more legal concerns.

Different people, societies, and cultures will disagree on where to draw the line. We are at a(n) ________ stage of technological development. And as we begin to uncover the great potential of brain science, the need to consider their implications for legal action becomes more ________.

No Filming at Concerts and Movie Theaters on Phones

“Please, no flash photography.”

Polite requests like this can be found in museums all over the world, but they generally don’t discourage people from taking photos of     1     they feel like. The same goes for concerts, movie theaters and other places     2     people routinely ignore filming restrictions. A new patent from Apple may block that rule-breaking feature—on phones at least.

The patent,     3     (award) to Apple today, outlines a system which would allow venues, like concert halls or theaters, to use an infrared emitter (红外发射器) to remotely disable the camera function on smartphones. According to the patent, infrared beams could be picked up by the camera, and interpreted by the smartphone as a command     4     (block) the user from taking any photos or videos.

Many musicians and performers have banned cellphones from their shows     5     they object to the free footage circulating around the web.     6     this, images still manage to leak out. Prince’s last concert before he passed away in April was supposed to be cellphone-free—it apparently wasn’t. If Apple’s patent     7     (introduce) into iPhone software, with venues putting infrared emitters around their stage, leaks like this could potentially stop happening.

But the patent also raises questions about the sort of power that this technology would be handing over to     8     with more immoral intentions.

Given the company’s rigid support of personal privacy when it comes to police requests to break into users’ devices, it’s possible that Apple just     9     (patent) the technology so that no one else will use it. But who knows, if it does intend to introduce this feature to future operating systems, sales of camcorders, or even GoPros, could get a much-needed boost, as people try to avoid     10     (use) the prohibitive software.
