Walter Mischel, The Marshallow Test, and Self-Control - The New Yorker - 1 views

  • Mischel’s story isn’t surprising—nicotine is addictive, and quitting is difficult—except for one thing: Mischel is the creator of the marshmallow test, one of the most famous experiments in the history of psychology, which is often cited as evidence of the importance of self-control. In the original test, which was administered at the Bing Nursery School, at Stanford, in the nineteen-sixties, Mischel’s team would present a child with a treat (marshmallows were just one option) and tell her that she could either eat the one treat immediately or wait alone in the room for several minutes until the researcher returned, at which point she could have two treats. The promised treats were always visible and the child knew that all she had to do to stop the agonizing wait was ring a bell to call the experimenter back—although in that case, she wouldn’t get the second treat. The longer a child delayed gratification, Mischel found—that is, the longer she was able to wait—the better she would fare later in life at numerous measures of what we now call executive function. She would perform better academically, earn more money, and be healthier and happier. She would also be more likely to avoid a number of negative outcomes, including jail time, obesity, and drug use.
  • It was not until one day in the late nineteen-sixties, when he saw a man with metastasized lung cancer in the halls of Stanford’s medical school—chest exposed, head shaved, little green “x” marks all over his body, marking the points where radiation would go—that Mischel realized he was fooling himself. Finally, something clicked. From then on, each time he wanted a cigarette (approximately every three minutes, by his count) he would create a picture in his mind of the man in the hallway. As he described it to me, “I changed the objective value of the cigarette. It went from something I craved to something disgusting.” He hasn’t had a smoke since.
  •  
    "Mischel, who is now eighty-four years old, has just published his first popular book, "The Marshmallow Test: Mastering Self-Control." It is part memoir, part scientific analysis, and part self-help guide. In the book, he describes the original impetus for the marshmallow study. At the time, his daughters, Judith, Rebecca, and Linda, were three, four, and five years old, respectively. "I began to see this fascinating phenomenon where they morphed from being highly impulsive, immediate creatures who couldn't delay anything," he told me. "There were these amazingly rapid changes-everything around them was the same, but something inside them had changed. I realized I didn't have a clue what was going on in their heads." He wondered what was it that had enabled them to go from deciding that they wanted to wait to actually being able to do so. He found the answer among their classmates at the Bing preschool."

How Children Learn To Read - The New Yorker - 0 views

  • Why is it easy for some people to learn to read, and difficult for others? It’s a tough question with a long history. We know that it’s not just about raw intelligence, nor is it wholly about repetition and dogged persistence. We also know that there are some conditions that, effort aside, can hold a child back. Socioeconomic status, for instance, has been reliably linked to reading achievement. And, regardless of background, children with lower general verbal ability and those who have difficulty with phonetic processing seem to struggle. But what underlies those differences? How do we learn to translate abstract symbols into meaningful sounds in the first place, and why are some children better at it than others?
  • When Hoeft took into account all of the explanatory factors that had been linked to reading difficulty in the past—genetic risk, environmental factors, pre-literate language ability, and over-all cognitive capacity—she found that only one thing consistently predicted how well a child would learn to read. That was the growth of white matter in one specific area of the brain, the left temporoparietal region. The amount of white matter that a child arrived with in kindergarten didn’t make a difference. But the change in volume between kindergarten and third grade did.
  • She likens it to the Dr. Seuss story of Horton and the egg. Horton sits on an egg that isn’t his own, and, because of his dedication, the creature that eventually hatches looks half like his mother, and half like the elephant. In this particular case, Hoeft and her colleagues can’t yet separate cause and effect: Were certain children predisposed to develop strong white-matter pathways that then helped them to learn to read, or was superior instruction and a rich environment prompting the building of those pathways?

What to Call a Doubter of Climate Change? - NYTimes.com - 0 views

  • People who reject the findings of climate science are dismissed as “deniers” and “disinformers.” Those who accept the science are attacked as “alarmists” or “warmistas. ” The latter term, evoking the Sandinista revolutionaries of Nicaragua, is perhaps meant to suggest that the science is part of some socialist plot.
  • The petition asks the news media to abandon the most frequently used term for people who question climate science, “skeptic,” and call them “climate deniers” instead. By Degrees A column by Justin Gillis about our changing climate. 3.6 Degrees of Uncertainty DEC 15 A Tricky Transition From Fossil Fuel NOV 10 Shining Star Power on a Crucial Subject SEP 22 In the Ocean, Clues to Change AUG 11 Picking Lesser of Two Climate Evils JUL 7 See More » Climate scientists are among the most vocal critics of using the term “climate skeptic” to describe people who flatly reject their findings. They point out that skepticism is the very foundation of the scientific method. The modern consensus about the risks of climate change, they say, is based on evidence that has piled up over the course of decades and has been subjected to critical scrutiny every step of the way.
  • In other words, the climate scientists see themselves as the true skeptics, having arrived at a durable consensus about emissions simply because the evidence of risk has become overwhelming. And in this view, people who reject the evidence are phony skeptics, arguing their case by cherry-picking studies, manipulating data, and refusing to weigh the evidence as a whole.The petition asking the media to drop the “climate skeptic” label began with Mark B. Boslough, a physicist in New Mexico who grew increasingly annoyed by the term over several years. The phrase is wrong, he said, because “these people do not embrace the scientific method.”

Executing Them Softly - NYTimes.com - 0 views

  • Since the late 19th century in the United States, critical responses to the spectacle of pain in executions have continued to spur ardent calls for the improvement of killing technology. One of the most prolific legal theorists of capital punishment, Austin Sarat, has concisely referred to this history: “The movement from hanging to electrocution, from electrocution to the gas chamber, from gas to lethal injection, reads like someone’s version of the triumph of progress, with each new technique enthusiastically embraced as the latest and best way to kill without imposing pain.” Recent debates over the administration of midazolam and pentobarbital, and in what dosage, seamlessly integrate themselves into Sarat’s grim progress narrative. The inexhaustible impulse to seek out less painful killing technologies puts a series of questions in sharp relief: What is, and should be, the role of pain in retributive justice? And how has the law come to rationalize the condemned’s experience of pain during an execution? While the Eighth Amendment stipulates the necessity of avoiding “cruel and unusual punishment,” in 1890 the Supreme Court decided this clause could mean that no method of execution should impose “something more than the mere extinguishment of life.” And then, in 1958, the court also determined that the amendment should reflect the “evolving standards of decency that mark the progress of a maturing society.” If we were to consider the “standard of decency” in our society today, we would be pushed to ask: By what moral order have we continued to establish the “extinguishment of life” as something “mere,” and the pain of the condemned as excessive? In other words, how has the pain experienced during an execution become considered cruel and unconstitutional but not the very act of killing itself? We should dial back to older histories of law to tap into pain’s perennially vexed role in retributive theories of justice.

Vermont Proposes Official Latin Motto, Wingnuts Tell Vermont To Go Back To Mexico | Won... - 0 views

  • Here’s a sweet little story of Democracy in Action. A bright eighth grader writes to her state legislator with an idea for a law: Vermont doesn’t have an official Latin motto, so why not adopt one? And for that matter, make it a reference to history? Neato! So state Sen. Joe Benning — a Republican who was actually trying to do a good thing, which he has probably learned to never try again — introduced a bill to adopt the motto “Stella quarta decima fulgeat.” — May the fourteenth star shine bright.” Because Vermont was the 14th state, see? Benning noted that when Vermont briefly minted its own currency, it was engraved with “Stella Quarta Deccima,” so the phrase had real historical cachet.ADVERTISEMENTAnd then Burlington TV station WCAX put the story on its Facebook page with the headline, “Should Vermont have an official Latin motto?” and all Stupid broke loose when morons thought that Vermont was knuckling under to a bunch of goddamned illegal immigrants. Charles Topher at “If you Only News” collected some of the worst of the over 600 comments from some of the geniuses worried about protecting ‘Merca from the invading Latin hordes:

Arguments Against God - NYTimes.com - 2 views

  • L.A.: O.K. So the question is, why do I say that theism is false, rather than just unproven? Because the question has been settled to my satisfaction. I say “there is no God” with the same confidence I say “there are no ghosts” or “there is no magic.” The main issue is supernaturalism — I deny that there are beings or phenomena outside the scope of natural law.
  • That’s not to say that I think everything is within the scope of human knowledge. Surely there are things not dreamt of in our philosophy, not to mention in our science – but that fact is not a reason to believe in supernatural beings. I think many arguments for the existence of a God depend on the insufficiencies of human cognition. I readily grant that we have cognitive limitations. But when we bump up against them, when we find we cannot explain something — like why the fundamental physical parameters happen to have the values that they have — the right conclusion to draw is that we just can’t explain the thing. That’s the proper place for agnosticism and humility. But getting back to your question: I’m puzzled why you are puzzled how rational people could disagree about the existence of God. Why not ask about disagreements among theists? Jews and Muslims disagree with Christians about the divinity of Jesus; Protestants disagree with Catholics about the virginity of Mary; Protestants disagree with Protestants about predestination, infant baptism and the inerrancy of the Bible. Hindus think there are many gods while Unitarians think there is at most one. Don’t all these disagreements demand explanation too? Must a Christian Scientist say that Episcopalians are just not thinking clearly? Are you going to ask a Catholic if she thinks there are no good reasons for believing in the angel Moroni?

Chinese teacher wakes up after stroke speaking English but no Chinese | Daily Mail Online - 2 views

  • However, she is not the only person to wake up from a coma speaking another language.Australian Ben McMahon woke up able to speak Mandarin after being involved in a car accident, while a 13-year-old Croatian girl woke up having replaced her fluency in her native language with speaking German. There was also the case of a U.S. navy veteran was found unconscious in a motel room who had no recollection of who he was and woke up speaking fluent Swedish. A Queensland Brain Institute neuroscientist suggested a possible explanation last year. Dr Pankaj Sah said the brain was made up of different circuits - which assist in language, breathing, speaking and thinking - similar to electronic circuits.According to him, it is possible in Ben's case that the parts of the brain which recalled English were damaged in the crash and those that retained Mandarin were activated when the 22-year-old woke up.Whether this is what happened to Ms Jieyu is not known. More commonly, people are known to have woken up with a different accent, like in the case of Kath Locket, who was born and bred in Stafford. But after she was rushed into hospital unable to speak or swallow, she developed a strong accent which was distinctly European.  WHAT IS FOREIGN ACCENT SYNDROME?

BBC News - China: Stroke patient loses Chinese language ability - 0 views

  • An elderly Chinese woman is only able to speak English after suffering a stroke, it's been reported. Liu Jaiyu, a 94-year-old former English teacher, has found herself no longer able to speak Chinese after parts of her brain relating to native language were damaged by a cerebral infarction, the local Hunan TV reports. Television pictures show her in bed, answering simple questions in English, which means the nursing staff are having to brush up on their language skills. "She greets me in the morning using English, after she's eaten her meals in the afternoon she uses English," one nurse tells the TV. "My memory of the language isn't too good, sometimes I don't understand what she's saying!" A doctor at the hospital says that Ms Liu is suffering from paralysis of all her limbs, as well as an "obstacle" to her language functions. "It seems the part of her brain responsible for her mother tongue has been damaged, however the part that uses English has been preserved," Li Yanfang says. There have been rare cases where patients develop a different accent after a stroke, migraine or head trauma. But Ms Liu's case appears different because she has apparently turned to an already-learned language. Experts say that the complex Chinese language requires the use of both parts of the brain, while English only uses one side.

BBC - Culture - The greatest mistranslations ever - 0 views

  •  
    "Life on Mars When Italian astronomer Giovanni Virginio Schiaparelli began mapping Mars in 1877, he inadvertently sparked an entire science-fiction oeuvre. The director of Milan's Brera Observatory dubbed dark and light areas on the planet's surface 'seas' and 'continents' - labelling what he thought were channels with the Italian word 'canali'. Unfortunately, his peers translated that as 'canals', launching a theory that they had been created by intelligent lifeforms on Mars. Convinced that the canals were real, US astronomer Percival Lowell mapped hundreds of them between 1894 and 1895. Over the following two decades he published three books on Mars with illustrations showing what he thought were artificial structures built to carry water by a brilliant race of engineers. One writer influenced by Lowell's theories published his own book about intelligent Martians. In The War of the Worlds, which first appeared in serialised form in 1897, H G Wells described an invasion of Earth by deadly Martians and spawned a sci-fi subgenre. A Princess of Mars, a novel by Edgar Rice Burroughs published in 1911, also features a dying Martian civilisation, using Schiaparelli's names for features on the planet. While the water-carrying artificial trenches were a product of language and a feverish imagination, astronomers now agree that there aren't any channels on the surface of Mars. According to Nasa, "The network of crisscrossing lines covering the surface of Mars was only a product of the human tendency to see patterns, even when patterns do not exist. When looking at a faint group of dark smudges, the eye tends to connect them with straight lines." "

The Moral Instinct - New York Times - 1 views

  • “Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them,” wrote Immanuel Kant, “the starry heavens above and the moral law within.” These days, the moral law within is being viewed with increasing awe, if not always admiration. The human moral sense turns out to be an organ of considerable complexity, with quirks that reflect its evolutionary history and its neurobiological foundations. These quirks are bound to have implications for the human predicament. Morality is not just any old topic in psychology but close to our conception of the meaning of life. Moral goodness is what gives each of us the sense that we are worthy human beings. We seek it in our friends and mates, nurture it in our children, advance it in our politics and justify it with our religions. A disrespect for morality is blamed for everyday sins and history’s worst atrocities. To carry this weight, the concept of morality would have to be bigger than any of us and outside all of us. So dissecting moral intuitions is no small matter. If morality is a mere trick of the brain, some may fear, our very grounds for being moral could be eroded. Yet as we shall see, the science of the moral sense can instead be seen as a way to strengthen those grounds, by clarifying what morality is and how it should steer our actions.

Can Torture Ever Be Moral? - NYTimes.com - 0 views

  • I think that torture is almost always morally wrong and that, for moral reasons, it ought to be prohibited absolutely in law. Torture has been used to extract confessions, to terrorize people associated with the victims, to punish presumed wrongdoers, and even to gratify and amuse sadists and bullies. These uses are always morally wrong. The only use of torture that has any chance of being morally justified is to gain important information. But even when torture is used to gain information, the torturers are usually wrongdoers seeking information that will help them to achieve their unjust aims. And even when those seeking information have just aims, their victims are often innocent, or lack the information sought, or are sufficiently strong-willed to mislead their torturers, so that the torture is ineffective or counterproductive. Still, both those pursuing unjust aims and those pursuing just aims will continue to be tempted to engage in torture if they can do so with impunity. Hence, torture has been widely practiced, though its use has almost invariably been wrong. This means that the overriding goal of the law ought to be to deter the wrongful use of torture, even at the cost of forbidding the use of torture in those rare cases in which it might be morally justified. The legal prohibition ought therefore to be absolute; for those who think that torture would be advantageous to them will always be tempted to try to exploit any legal permission to use it.

How Do We Increase Empathy? - NYTimes.com - 0 views

  • “Probably the biggest empathy generator is cuteness: paedomorphic features such as large eyes, a large head, and a small lower face,” Steven Pinker, the Harvard psychologist, tells me. “Professional empathy entrepreneurs have long known this, of course, which is why so many charities feature photos of children and why so many conservation organizations feature pandas. Prettier children are more likely to be adopted, and baby-faced defendants get lighter sentences.”
  • Likewise, the wealthiest 20 percent of Americans give significantly less to charity as a fraction of income (1.4 percent) than the poorest 20 percent do (3.5 percent), according to Bureau of Labor Statistics data. That may be partly because affluence insulates us from need, so that disadvantage becomes theoretical and remote rather than a person in front of us. Wealthy people who live in economically diverse areas are more generous than those who live in exclusively wealthy areas.
  • Professor Pinker, in his superb book “The Better Angels of Our Nature,” explores whether the spread of affordable fiction and journalism beginning in the 18th century expanded empathy by making it easier for people to imagine themselves in the shoes of others. Researchers have found that reading literary fiction by the likes of Don DeLillo or Alice Munro — but not beach fiction or nonfiction — can promote empathy.
  • ...1 more annotation...
  • Yet I’ve come to believe that service trips do open eyes and remind students of their good fortune. In short, they build empathy.So let’s escape the insulation of our comfort zones. Let’s encourage student service projects and travel to distant countries and to needy areas nearby. Whatever the impact on others, volunteering may at least help the volunteer.

Is Bilingualism Really an Advantage? - The New Yorker - 1 views

  • Many modern language researchers agree with that premise. Not only does speaking multiple languages help us to communicate but bilingualism (or multilingualism) may actually confer distinct advantages to the developing brain. Because a bilingual child switches between languages, the theory goes, she develops enhanced executive control, or the ability to effectively manage what are called higher cognitive processes, such as problem-solving, memory, and thought. She becomes better able to inhibit some responses, promote others, and generally emerges with a more flexible and agile mind. It’s a phenomenon that researchers call the bilingual advantage.
  • For the first half of the twentieth century, researchers actually thought that bilingualism put a child at a disadvantage, something that hurt her I.Q. and verbal development. But, in recent years, the notion of a bilingual advantage has emerged from research to the contrary, research that has seemed both far-reaching and compelling, much of it coming from the careful work of the psychologist Ellen Bialystok. For many tasks, including ones that involve working memory, bilingual speakers seem to have an edge. In a 2012 review of the evidence, Bialystok showed that bilinguals did indeed show enhanced executive control, a quality that has been linked, among other things, to better academic performance. And when it comes to qualities like sustained attention and switching between tasks effectively, bilinguals often come out ahead. It seems fairly evident then that, given a choice, you should raise your child to speak more than one language.
  • Systematically, de Bruin combed through conference abstracts from a hundred and sixty-nine conferences, between 1999 and 2012, that had to do with bilingualism and executive control. The rationale was straightforward: conferences are places where people present in-progress research. They report on studies that they are running, initial results, initial thoughts. If there were a systematic bias in the field against reporting negative results—that is, results that show no effects of bilingualism—then there should be many more findings of that sort presented at conferences than actually become published. That’s precisely what de Bruin found. At conferences, about half the presented results provided either complete or partial support for the bilingual advantage on certain tasks, while half provided partial or complete refutation. When it came to the publications that appeared after the preliminary presentation, though, the split was decidedly different. Sixty-eight per cent of the studies that demonstrated a bilingual advantage found a home in a scientific journal, compared to just twenty-nine per cent of those that found either no difference or a monolingual edge. “Our overview,” de Bruin concluded, “shows that there is a distorted image of the actual study outcomes on bilingualism, with researchers (and media) believing that the positive effect of bilingualism on nonlinguistic cognitive processes is strong and unchallenged.”

How the Brain Stores Trivial Memories, Just in Case - NYTimes.com - 0 views

  • The surge of emotion that makes memories of embarrassment, triumph and disappointment so vivid can also reach back in time, strengthening recall of seemingly mundane things that happened just beforehand and that, in retrospect, are relevant, a new study has found.The report, published Wednesday in the journal Nature, suggests that the television detective’s standard query — “Do you remember any unusual behavior in the days before the murder?” — is based on solid brain science, at least in some circumstances.The findings fit into the predominant theory of memory: that it is an adaptive process, continually updating itself according to what knowledge may be important in the future.The new study suggests that human memory has, in effect, a just-in-case file, keeping seemingly trivial sights, sounds and observations in cold storage for a time in case they become useful later on.

BBC News - Are most victims of terrorism Muslim? - 1 views

  • After the Charlie Hebdo attack, a Paris imam went to the scene and condemned the murders. "These victims are martyrs, and I shall pray for them with all my heart," said Hassen Chalghoumi (above). He was also quoted as saying that 95% of victims of terrorism are Muslim. How accurate is this statistic?
  • When people in the West think of terrorist attacks, they may think of Charlie Hebdo, or the 7/7 London tube and bus bombs, the Madrid train bombs and of course 9/11 - and although some Muslims did die in these attacks, most of the victims wouldn't have been Muslim. The overall number of deadly terrorist attacks in France, the UK, Spain and the US, however, is very low by international standards. Between 2004-2013, the UK suffered 400 terrorist attacks, mostly in Northern Ireland, and almost all of them were non-lethal. The US suffered 131 attacks, fewer than 20 of which were lethal. France suffered 47 attacks. But in Iraq, there were 12,000 attacks and 8,000 of them were lethal.

Why Ants Handle Traffic Better Than You Do : NPR - 0 views

  • Could studying ants reveal clues to reducing highway traffic jams? Physicist Apoorva Nagar at the Indian Institute of Space Science and Technology thinks the answer is yes. Nagar says he got interested in the topic when he came across a study by German and Indian researchers showing that ants running along a path were able to maintain a steady speed even when there were a large number of ants on the path. Nagar says there are three main reasons ants don't jam up. Number one, ants don't have egos. They don't show off by zooming past people. "The second thing is, they do not mind a few accidents, or collisions," say Nagar. So unless there's a serious pileup, they just keep going.
  • The third reason, he says, is that ants seem to get more disciplined when paths get crowded, running in straighter lines, and varying their speed less. They're less likely to make unexpected moves in this sort of heavy traffic. It's the kind of steady control you see when a computer is controlling a car rather than a human. There's less variability unless it's absolutely called for. Nagar felt this kind of behavior could be explained by something called the Langevin equation, an equation physicists use when describing the movement of liquids, or how individual atoms behave in a lattice.
