How Play Energizes Your Kid's Brain - The New York Times - 0 views

  • To the untrained eye, play can seem aimless, repetitive, wild or foolish. But play can offer a window into the developing mind. Piaget viewed certain kinds of play as milestones, signs that a child had reached a new stage of development.
  • nstead of simply making objects move through space, they begin to make believe. A banana might become a telephone and a pencil might take flight like an airplane.
  • That is, the ones who could imagine hypotheticals that hadn’t occurred were also the best at pretending to operate an imaginary machine with an imaginary zando.

  • Mulling over past “what ifs” helps us better plan for the future.
  • “That’s a very important, very distinctive human ability,”
  • That means separating actual events from possible events and pretend play helps children do that. What would happen if I could use this banana to call my grandma? What if this pencil could take flight
  • by pretending, children are practicing deciphering others’ emotions and beliefs. But an alternate hypothesis is that pretend play helps kids develop a skill known as counterfactual reasoning.
  • Open the box, they told the kids, and you’ll be able to play with the toy.
  • They asked a quarter of the children to pretend to be someone else while they completed the task — Batman or an intrepid adventurer like Dora the Explorer.
  • And the kids did get frustrated. In an odd twist, none of the keys actually worked
  • The children who pretended to be the hardworking fictional characters stayed calmer. They also spent more time trying to open the box and tried more keys.
  • For kids, of course, play isn’t about learning or planning or regulating emotions. It’s about having fun. Play may be “evolution’s way of building in an insurance policy” to learn and develop, said Dr. Feigenson. It’s so enjoyable that most kids can’t resist, and along the way they develop the skills they need to succeed as adults.

But most of my brain is saying, ‘OK, Trump wins and New York is not getting a fiscal bailout and we’re going to lose more ground on the environment, we’re going to lose on Roe v. Wade, we’re going to lose on health care.’”
  • It’s hard to overstate the degree of anxiety in America right now, as the country confronts a Hydra of troubles: the pandemic, the economy, the fires, the protests, the violent plots against public officials, the assault on voting rights, the state-sponsored disinformation, the sense that democracy itself is on the ballot.

  • “Polls give people a false sense of security, and they think they don’t have to turn out to vote,” he said. “Is there going to be a peaceful transfer of power? That’s a big question. The big worry is that he won’t accept the results, or he’s going to incite violence.”

Starbucks v Dunkin': how capitalism gives us the illusion of choice | Richard Reeves | Opinion | The Guardian - 0 views

  • US adults are three times as likely to have a “very favorable” view of small businesses as they are of large enterprises (59% v 17%), according to a 2018 survey from the Public Affairs Council.
  • The nostalgia for small-town life and “mom and pop” stores stands in stark contrast not only to an urbanized population but the power of large companies.

  • Big companies dominate consumption. This is not a bad thing in itself.

Human Brain: facts and information - 0 views

  • The human brain is more complex than any other known structure in the universe.
  • Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.
  • The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Animals such as elephants, dolphins, and whales actually have larger brains, but humans have the most developed cerebrum. It's packed to capacity inside our skulls, with deep folds that cleverly maximize the total surface area of the cortex.
  • ...18 more annotations...
  • The cerebrum has two halves, or hemispheres, that are further divided into four regions, or lobes. The frontal lobes, located behind the forehead, are involved with speech, thought, learning, emotion, and movement.
  • Behind them are the parietal lobes, which process sensory information such as touch, temperature, and pain.
  • At the rear of the brain are the occipital lobes, dealing with vision
  • Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.
  • The second-largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum.
  • diencephalon, located in the core of the brain. A complex of structures roughly the size of an apricot, its two major sections are the thalamus and hypothalamus
  • The brain is extremely sensitive and delicate, and so it requires maximum protection, which is provided by the hard bone of the skull and three tough membranes called meninges.
  • Want more proof that the brain is extraordinary? Look no further than the blood-brain barrier.
  • This led scientists to learn that the brain has an ingenious, protective layer. Called the blood-brain barrier, it’s made up of special, tightly bound cells that together function as a kind of semi-permeable gate throughout most of the organ. It keeps the brain environment safe and stable by preventing some toxins, pathogens, and other harmful substances from entering the brain through the bloodstream, while simultaneously allowing oxygen and vital nutrients to pass through.
  • One in five Americans suffers from some form of neurological damage, a wide-ranging list that includes stroke, epilepsy, and cerebral palsy, as well as dementia.
  • Alzheimer’s disease, which is characterized in part by a gradual progression of short-term memory loss, disorientation, and mood swings, is the most common cause of dementia. It is the sixth leading cause of death in the United States
  • 50 million people suffer from Alzheimer’s or some form of dementia. While there are a handful of drugs available to mitigate Alzheimer’s symptoms, there is no cure.
  • Unfortunately, negative attitudes toward people who suffer from mental illness are widespread. The stigma attached to mental illness can create feelings of shame, embarrassment, and rejection, causing many people to suffer in silence.
  • In the United States, where anxiety disorders are the most common forms of mental illness, only about 40 percent of sufferers receive treatment. Anxiety disorders often stem from abnormalities in the brain’s hippocampus and prefrontal cortex.
  • Attention-deficit/hyperactivity disorder, or ADHD, is a mental health condition that also affects adults but is far more often diagnosed in children.
  • ADHD is characterized by hyperactivity and an inability to stay focused.
  • Depression is another common mental health condition. It is the leading cause of disability worldwide and is often accompanied by anxiety. Depression can be marked by an array of symptoms, including persistent sadness, irritability, and changes in appetite.
  • The good news is that in general, anxiety and depression are highly treatable through various medications—which help the brain use certain chemicals more efficiently—and through forms of therapy

It's Science: Eat Dinner Together - The Family Dinner Project - The Family Dinner Project - 0 views

  • It turns out that sitting down for a nightly meal is great for the brain, the body and the spirit
  • And that nightly dinner doesn’t have to be a gourmet meal that took three hours to cook, nor does it need to be made with organic arugula and heirloom parsnips.
  • For starters, researchers found that for young children, dinnertime conversation boosts vocabulary even more than being read aloud t
  • ...14 more annotations...
  • Other researchers reported a consistent association between family dinner frequency and teen academic performance. Adolescents who ate family meals 5 to 7 times a week were twice as likely to get A’s in school as those who ate dinner with their families fewer than two times a week.
  • Children who eat regular family dinners also consume more fruits, vegetables, vitamins and micronutrients, as well as fewer fried foods and soft drinks.
  • And the nutritional benefits keep paying dividends even after kids grow up: young adults who ate regular family meals as teens are less likely to be obese and more likely to eat healthily once they live on their own.
  • Some research has even found a connection between regular family dinners and the reduction of symptoms in medical disorders, such as asthma.
  • The benefit might be due to two possible byproducts of a shared family meal: lower anxiety and the chance to check in about a child’s medication compliance.
  • The dinner atmosphere is also important. Parents need to be warm and engaged, rather than controlling and restrictive, to encourage healthy eating in their children.
  • In a very recent study, kids who had been victims of cyberbullying bounced back more readily if they had regular family dinners.
  • Family dinners have been found to be a more powerful deterrent against high-risk teen behaviors than church attendance or good grades.
  • In a New Zealand study, a higher frequency of family meals was strongly associated with positive moods in adolescents. Similarly, other researchers have shown that teens who dine regularly with their families also have a more positive view of the future, compared to their peers who don’t eat with parents.
  • dinner is the most reliable way for families to connect and find out what’s going on with each other
  • American teens were asked when they were most likely to talk with their parents: dinner was their top answer
  • Kids who eat dinner with their parents experience less stress and have a better relationship with them
  • Of course, the real power of dinners lies in their interpersonal quality. If family members sit in stony silence, if parents yell at each other, or scold their kids, family dinner won’t confer positive benefits.
  • But, dinner may be the one time of the day when a parent and child can share a positive experience – a well-cooked meal, a joke, or a story – and these small moments can gain momentum to create stronger connections away from the table.

The Best Educational Systems in the World - 0 views

  • In 2020, the top three educational systems in the world were Finland, Denmark, and South Korea
  • This is based on developmental levels including early childhood enrollment, test scores in math, reading, and science in primary and secondary levels, completion rates, high school and college graduation, and adult literacy rates.
  • Finland's education system is a dream: early education is designed around learning through play, school meals are free, and universities are tuition-free for students coming from EU, European Economic Area (EEA) countries, and Switzerland. A majority of teachers also have a master's degree; in fact, basic education teachers are required to have them.

Asking yourself 'What's the meaning of life?' may extend it - CNN - 0 views

  • "What is the meaning of life?" It's one of those enormous questions that's so important -- both philosophically and practically, in terms of how we live our lives -- and yet we rarely, if ever, stop to really think about the answer.
  • After studying 1,300 subjects from ages 21 to more than 100, the authors found that older people were more likely to have found their life's purpose, while younger people were more likely still searching. That's logical, given that wisdom is often born from experience. According to research by Stanford education professor William Damon, the author of "The Path to Purpose," only 20% of young adults have a fully realized sense of their life's meaning.And according to the new study, the presence of meaning in one's life showed a positive correlation to one's health, including improved cognitive function, while searching for it may have a slight negative effect. Mental and physical well-being was self-reported, and having a sense of purpose tended to peak around age 60, the study found.
  • According to two other studies published in 2014 -- one among 9,000 participants over age 65 and another among 6,000 people between 20 and 75 -- those who could articulate the meaning and purpose of their lives lived longer than those who saw their lives as aimless. It didn't seem to matter what meaning participants ascribed to their life, whether it was personal (like happiness), creative (like making art) or altruistic (like making the world a better place). It was having an answer to the question that mattered.
  • ...4 more annotations...
  • Great thinkers (and celebrities) have given the question thought, so you can look to the words attributed to them for inspiration. Aristotle, the Greek philosopher who lived 2,500 years ago, is believed to have written that the essence of life is "to serve others and to do good," and the Roman philosopher Cicero, born 280 years later, came to the same conclusion. As did Russian author Leo Tolstoy, who wrote, "The sole meaning of life is to serve humanity." And His Holiness the Dalai Lama added, "if you can't help them, at least don't hurt them."
  • My favorite answer, though, is the Zen-like circular reasoning attributed to writer Robert Byrne, who put it, "The purpose of life is a life of purpose."
  • Some have concluded that life's meaning is subjective. "There is not one big cosmic meaning for all," Anaïs Nin wrote in her diary. "There is only the meaning we each give to our life, an individual meaning, an individual plot, like an individual novel, a book for each person."
  • In 1997, my answer was "the discovery, pursuit and attainment of one's bliss," inspired by myth expert Joseph Campbell. A year later, is was to make "the world a better place." In 2002, the year I got engaged, it was simply "Love." And the year we conceived our oldest daughter, it was the less-romantic "continuation of one's DNA to the next generation." But most years, my answer is some combination of love, legacy, happiness, experience and helping others.

The Truth About Photographic Memory | Psychology Today - 0 views

  • According to mounting evidence, it's impossible to recall images with near perfect accuracy.
  • But people with Herculean memories tend to be adept at one specific task—i.e., a person who memorizes cards may be inept at recognizing faces.

  • While people can improve their recall through tricks and practice, eidetikers are born, not made, says Searleman. The ability isn't linked to other traits, such as high intelligence. Children are more likely to possess eidetic memory than adults, though they begin losing the ability after age six as they learn to process information more abstractly.
  • Although psychologists don't know why children lose the ability, the loss of this skill may be functional: Were humans to remember every single image, it would be difficult to make it through the day.

7 Surprising Ways Cell Phones Affect Your Health - ABC News - 0 views

  • In a study published in the journal Annals of Clinical Microbiology, researchers at Ondokuz Mayis University in Samsun, Turkey screened the mobile phones of 200 health care workers in hospitals for germs that are known to be dangerous to human health.
  • The solution to this problem may be decidedly low tech -- disinfectant spray and a paper towel.
  • Specifically, researchers at Carnegie Mellon University studied the brain waves of drivers using cell phones -- and they found that even just listening to a conversation reduced the amount of brain activity devoted to driving by 37 percent
  • ...8 more annotations...
  • "The science tells [us] when [we're] on the phone while driving, it is a high-risk activity -- very, very risky,"
  • Even hands-free phones appear to contribute to unsafe driving
  • What they found was that when children were on the cell phones, their attention to traffic -- the number of times a participant looked right or left -- went down 20 percent. The risk of getting hit by a car, or the number of close calls, went up 43 percent
  • Our reliance on our cell phones may actually be "training" some of us to believe it is vibrating when it is not. In the case of cell phones, people are rewarded when they pick up their calls and read their incoming text messages, which causes them to pick up their cell phones more and more frequently.
  • The sores and blisters that some experience from too much texting and typing have earned monikers such as "BlackBerry thumb." And while the sore thumbs may seem like a new phenomenon, medical experts say there is a rational explanation for this modern-day nuisance.
  • These sorts of injuries, known as repetitive strain injuries or a repetitive motion disorders, are sometimes minor. But they can also lead to serious medical problems.
  • According to statistics from the U.S. Centers for Disease Control and Prevention (http://www.cdc.gov/healthyyouth/noise/index.htm), about 12.5 percent of children and adolescents 6 and 19 years old and 17 percent of adults between 20 and 69 years of age have suffered permanent damage to their hearing from excessive exposure to noise. In total, this accounts for more than 30 million people.
  • Sounds louder than 85 decibels can damage hearing. Normal conversation is about 60 decibels, and stereo headphones out of our MP3-enabled devices often reach 100 decibels.

What scientists know so far about the effects of coronavirus on children | Jonathan Ball | Opinion | The Guardian - 0 views

  • These were the groups initially urged to socially distance themselves. But we’re beginning to see that coronavirus can make some younger people seriously ill.
  • Compared to other European countries, the UK was slow in closing schools – waiting until there had already been 104 deaths due to coronavirus to take action. Studies from China showed children were rarely diagnosed with novel coronavirus, and therefore presumably had little role in the spread of the disease.
  • Like many of my colleagues, I could see no obvious reason why children weren’t being infected: this was a virus spread by the respiratory route, not through a process unique to adults. If significant numbers of children were infected and suffered very minor cold-like symptoms, then their potential to spread the virus was immense.
  • ...2 more annotations...
  • The current coronavirus is different. In more than 85% of confirmed cases symptoms can go undetected or be easily confused with the common cold of mild flu. Its biggest weapon – the thing that has, according to one study, allowed it to spread so easily – is this ability to cause mild disease in the majority of people it infects. When you can’t easily tell if someone has a cold or coronavirus, case identification and infection control are far more difficult.
  • Judging from past pandemics, school closures can be an effective way to reduce the spread of a virus – particularly when they form part of a larger programme of social distancing measures. Every school day, children congregate en masse, often in close proximity, and then return home, taking with them any new infection they’ve picked up. Intuitively, reducing this cycle should help slow the virus.

Sensory perception | Science Features | Naked Scientists - 0 views

  • Deciphering how the brain processes sight and hearing could have implications for how we understand and treat conditions such as dyslexia, autism and schizophrenia.
  • schizophrenia
  • Through a project called SENSOCOM, she is exploring how sensory perception affects communication, focusing on the brain’s deep subcortical structures.By doing this, she and her team are exploring a part of the brain traditionally excluded by research trying to understand communication impairments found in autism spectrum disorder and dyslexia, conditions which affect around 53 million people in Europe.
  • ...5 more annotations...
  • To do this they have been focusing on the sensory pathways linked to these deep structures. She and her group discovered that adults with dyslexia have weaker pathway connections between a visual subcortical structure (the left visual thalamus) with an area of the cortex called V5/MT, which is critical for the perception of visual motion. In the auditory mode, there was a similar finding. The team discovered weaker connections between the left auditory thalamus and a cortex structure linked to auditory motion, which is important for speech perception. These connections could therefore be important for reading and for predicting reading skill, according to Dr von Kriegstein.
  • So how might this translate into helping people with dyslexia? This is basic science, says Prof. von Kriegstein, so first it’s crucial to understand the mechanisms behind communications disorders before developing therapy training tools, although she is optimistic these could lie within reach.
  • The way the brain encodes information and in turn directs perception of that sensory experience is a highly variable process.
  • The sensory overload or distorted and heightened perceptions described by schizophrenia patients, for instance, could relate to these deficits. Sensory dysfunction has also been linked to delusions and hallucinations as well as difficulties with attention and reading the emotions or tone of others – all of which can affect social interaction.
  • According to Dr Fellin, decreased connectivity between nerve cells (neurons) appears to play an important role in the progression of schizophrenia. So far, Dr Fellin and his group have identified which specific neurons influence sensory responses in mouse studies, but not yet in animal models of schizophrenia, with similar investigations in glial cells  - the supporting cells of the nervous system.

Schizophrenia study finds evidence of reduced links between brain cells | Science | The Guardian - 0 views

  • A groundbreaking brain-scanning technique has uncovered evidence that suggests schizophrenia is linked to a loss of connections between brain cells.
  • They used a tracer that binds to the protein and which emits a signal that can be picked up by a PET brain scan, which provided an indirect measure of the density of connections. The team scanned 18 adults with schizophrenia and compared them with 18 people without the condition. They found that levels of SV2A were significantly lower in the front of the brain – the region involved in planning – in people with schizophrenia.

How the Brain Deletes Old Memories | Science | AAAS - 0 views

  • Although the precise role of neurogenesis in memory is still controversial, more than a decade of research has demonstrated that boosting neurogenesis with exercise and antidepressants such as Prozac can increase rodents' ability to learn new information about places and events. A few years ago, however, neuroscientist Paul Frankland of the Hospital for Sick Children in Toronto, Canada, noticed that some of the animals in his experiment actually did worse on certain memory tasks when their neuron birth rates had been ramped up. In particular, they performed poorly on tests that required them to retain details about past events.
  • It is difficult to completely eliminate the birth of new neurons in infant mice, but by genetically engineering dividing neural stem cells to self-destruct the team was able to achieve about a 50% reduction of neurogenesis in the animals, Frankland says. With less neurogenesis, the young rodents acted more like adult mice in the experiment. They froze when first placed in the box for roughly a week, rather than just 1 day, after receiving the foot shocks.

  • "A law enforcement source and another source familiar with the matter tell CNN that first lady Melania Trump and their son, Barron, were also taken to the bunker.
  • So, why would Trump describe it falsely to Fox? Especially when there are a few other things going on in the country -- most notably ongoing protests over the murder of a black man at the hands of police in Minneapolis and a global pandemic that has killed 106,000 Americans and is projected to kill 135,000 by early August.
  • There is nothing Trump hates more than weakness. And the image of him cowering in an underground bunker while protesters stood outside the gates of the White House is simply not something he cannot accept. This is a man who has been telling himself a story of his life -- one in which he is always the toughest, the smartest and the winner-est -- for, well, his entire adult life.
  • He could have gone anytime, of course! It was just a coincidence he was down there amid the protests outside the White House! Just going down to make sure all the buttons worked! All the brass was sufficiently polished! And the like.
