By MAX BEARAK MUMBAI, India — The young man sat cross-legged atop a cushioned divan on an ornately decorated stage, surrounded by other Jain monks draped in white cloth. His lip occasionally twitched, his hands lay limp in his lap, and for the most part his eyes were closed. An announcer repeatedly chastised the crowd for making even the slightest noise. From daybreak until midafternoon, members of the audience approached the stage, one at a time, to show the young monk a random object, pose a math problem, or speak a word or phrase in one of at least six different languages. He absorbed the miscellany silently, letting it slide into his mind, as onlookers in their seats jotted everything down on paper. After six hours, the 500th and last item was uttered — it was the number 100,008. An anxious hush descended over the crowd. And the monk opened his eyes and calmly recalled all 500 items, in order, detouring only once to fill in a blank he had momentarily set aside. When he was done, and the note-keepers in the audience had confirmed his achievement, the tense atmosphere dissolved and the announcer led the crowd in a series of triumphant chants. The opportunity to witness the feat of memory drew a capacity crowd of 6,000 to the Sardar Vallabhbhai Patel stadium in Mumbai on Sunday. The exhibition was part of a campaign to encourage schoolchildren to use meditation to build brainpower, as Jain monks have done for centuries in India, a country drawn both toward ancient religious practices and more recent ambitions. But even by Jain standards, the young monk — Munishri Ajitchandrasagarji, 24 — is something special. His guru, P. P. Acharya Nayachandrasagarji, said no other monk in many years had come close to his ability. © 2014 The New York Times Company
James Gorman Evidence has been mounting for a while that birds and other animals can count, particularly when the things being counted are items of food. But most of the research is done under controlled conditions. In a recent experiment with New Zealand robins, Alexis Garland and Jason Low at Victoria University of Wellington tested the birds in a natural setting, giving them no training and no rewards, and showed that they knew perfectly well when a scientist had showed them two mealworms in a box, but then delivered only one. The researchers reported the work this fall in the journal Behavioural Processes. The experiment is intriguing to watch, partly because it looks like a child’s magic trick. The apparatus used is a wooden box that has a sliding drawer. After clearly showing a robin that she was dropping two mealworms in a circular well in the box, Dr. Garland would slide in the drawer. It covered the two worms with an identical-looking circular well containing only one worm. When the researcher moved away and the robin flew down and lifted off a cover, it would find only one worm. The robins pecked intensely at the box, behavior they didn’t show if they found the two worms they were expecting. Earlier experiments had also shown the birds to be good at counting, and Dr. Garland said that one reason might be that they are inveterate thieves. Mates, in particular, steal from one another’s food caches, where they hide perishable prey like worms or insects. “If you’ve got a mate that steals 50 or more percent of your food,” she said, you’d better learn how to keep track of how many mealworms you’ve got. © 2014 The New York Times Company
By Anna North Do you devour the latest neuroscience news, eager to learn more about how your brain works? Or do you click past it to something else, something more applicable to your life? If you’re in the latter camp, you may be in the majority. A new study suggests that many people just don’t pay that much attention to brain science, and its findings may raise a question: Is “neuro-literacy” really necessary? At Wired, Christian Jarrett writes, “It feels to me like interest in the brain has exploded.” He cites the prevalence of the word “brain” in headlines as well as “the emergence of new fields such as neuroleadership, neuroaesthetics and neuro-law.” But as a neuroscience writer, he notes, he may be “heavily biased” — and in fact, some research “suggests neuroscience has yet to make an impact on most people’s everyday lives.” For instance, he reports, Cliodhna O’Connor and Helene Joffe recently interviewed 48 Londoners about brain science for a paper published in the journal Science Communication. Anyone who thinks we live in an era of neuro-fixation may find the results a bit of a shock. Said one participant in the research: “Science of the brain? I haven’t a clue. Nothing at all. I’d be lying if I said there was.” Another: “Brain research I understand, an image of, I don’t know, a monkey or a dog with like the top of their head off and electrodes and stuff on their brain.” And another: “I might have seen it on the news or something, you know, some report of some description. But because they probably mentioned the word ‘science,’ or ‘We’re going to go now to our science correspondent Mr. Lala,’ that’s probably when I go, okay, it’s time for me to make a cup of tea.” According to the study authors, 71 percent of respondents “took pains to convey that neuroscience was not salient in their day-to-day life: it was ‘just not really on my radar.’” Some respondents associated brain research with scientists in white coats or with science classes (asked to free-associate about the term “brain research,” one respondent drew a mean-faced stick figure labeled “cross teacher”). And 42 percent saw science as something alien to them, removed from their own lives. © 2014 The New York Times Company

By ALAN SCHWARZ CONCORD, Calif. — Every time Matthias is kicked out of a school or day camp for defying adults and clashing with other children, his mother, Joelle Kendle, inches closer to a decision she dreads. With each morning of arm-twisting and leg-flailing as she tries to get him dressed and out the door for first grade, the temptation intensifies. Ms. Kendle is torn over whether to have Matthias, just 6 and already taking the stimulant Adderall for attention deficit hyperactivity disorder, go on a second and more potent medication: the antipsychotic Risperdal. Her dilemma is shared by a steadily rising number of American families who are using multiple psychotropic drugs — stimulants, antipsychotics, antidepressants and others — to temper their children’s troublesome behavior, even though many doctors who mix such medications acknowledge that little is known about the overall benefits and risks for children. In 2012 about one in 54 youngsters ages 6 through 17 covered by private insurance was taking at least two psychotropic medications — a rise of 44 percent in four years, according to Express Scripts, which processes prescriptions for 85 million Americans. Academic studies of children covered by Medicaid have also found higher rates and growth. Combined, the data suggest that about one million children are currently taking various combinations of psychotropics. Risks of antipsychotics alone, for example, are known to include substantial weight gain and diabetes. Stimulants can cause appetite suppression, insomnia and, far more infrequently, hallucinations. Some combinations of medication classes, like antipsychotics and antidepressants, have shown improved benefits (for psychotic depression) but also heightened risks (for heart rhythm disturbances). But this knowledge has been derived substantially from studies in adults — children are rarely studied because of concerns about safety and ethics — leaving many experts worried that the use of multiple psychotropics in youngsters has not been explored fully. There is also debate over whether the United States Food and Drug Administration’s database of patients’ adverse drug reactions reliably monitors the hazards of psychotropic drug combinations, primarily because only a small fraction of cases are ever reported. Some clinicians are left somewhat queasy about relying mostly on anecdotal reports of benefit and harm. © 2014 The New York Times Company
By Paula Span A few days after I wrote about conditions that can mimic dementia, reader Sue Murray emailed me from Westchester County. Her subject line: “Have you heard of Charles Bonnet Syndrome?” I hadn’t, and until about six months ago, neither had Ms. Murray. Her mother Elizabeth, who is 91, has glaucoma and macular degeneration, and has been gradually losing her vision, Ms. Murray explained. So at first, her family was excited when Elizabeth seemed to be seeing things more clearly. Maybe, they thought, her vision was returning. But the things she was seeing — patterns and colors, strangers, a green man — weren’t there. She insisted that “there were people in the cellar, people on the porch, people in the house,” Ms. Murray said. “She’d point and say, ‘Don’t you see them?’ And she’d get mad when we didn’t.” Elizabeth and her husband Victor, 95, live in Connecticut, in a house they bought 50 years ago. For a while, the Green Man, as Elizabeth began calling him, seemed to have moved in, too. “She’d start hiding things in the closet so the Green Man wouldn’t take them,” Ms. Murray said. “There wasn’t any real fear; it was just, ‘Look at that!’” Elizabeth’s ophthalmologist promptly supplied the name for this condition: Charles Bonnet Syndrome, named for a Swiss philosopher who described such visual hallucinations in the 18th century. “We were relieved,” said Ms. Murray. What they feared, of course, was mental illness or dementia. “To have an eye doctor say, ‘I’m familiar with this,’ it’s still jarring but it’s not so terrible.” Bonnet Syndrome (pronounced Boh-NAY) isn’t terribly rare, it turns out. Oliver Sacks described several cases in his 2012 book, “Hallucinations.” Dr. Abdhish Bhavsar, a clinical spokesperson for the American Academy of Ophthalmology and a retina specialist in Minneapolis, estimates that he has probably seen about 200 patients with the syndrome over 17 years of practice. © 2014 The New York Times Company
By Meeri Kim Patients suffering from pagophagia compulsively crave and chomp on ice, even scraping buildup off freezer walls for a fix. The disorder appears to be caused by an iron deficiency, and supplements of the mineral tend to ease the cravings. But what is it about ice that makes it so irresistible? A new study proposes that, like a strong cup of coffee, ice may give those with insufficient iron a much-needed mental boost. Fatigue is the most common symptom of iron-deficiency anemia, which occurs when the body can’t produce enough oxygen-carrying hemoglobin because of low iron. “I had a friend who was suffering from iron-deficiency anemia who was just crunching through massive amounts of ice a day,” said study author Melissa Hunt, a clinical psychologist at the University of Pennsylvania. “She said: ‘It’s like a cup of coffee. I don’t feel awake until I have a cup of ice in my hand.’ ” Hunt and her colleagues had both anemic and healthy subjects complete a standardized, 22-minute attention test commonly used to diagnose attention deficit hyperactivity disorder. Just before the test, participants were given either a cup of ice or lukewarm water to consume. Iron-deficient subjects who had sipped on water performed far more slugglishly on the test than controls, as expected. But those who ate ice beforehand did just as well as their healthy counterparts. For healthy subjects, having a cup of ice instead of water appeared to make no difference in test performance. “It’s not like craving a dessert. It’s more like needing a cup of coffee or that cigarette,” Hunt said.

By Katy Waldman How much control do you have over how much control you think you have? The researchers Michael R. Ent and Roy F. Baumeister have been studying what makes a person more or less likely to believe in free will. Is it a deep connection to the philosophy of David Hume? An abiding faith in divine omnipotence? Try a really, really full bladder. In an online survey, 81 adults ages 18 to 70 reported the extent to which they felt hungry, tired, desirous of sex, and desirous of a toilet. They then rated the extent to which they considered themselves in command of their destinies. People experiencing intense physical needs were less likely to say they believed in free will. People who were not inexplicably taking an online survey while desperately holding in their pee (or starving, or wanting sex, or trying to stay awake) mostly claimed that the universe had handed them the keys to their lives. Also, people who brought their laptops with them into the bathroom to fill out the survey reported that they were God. (I kid on that last part.) Ent and Baumeister also used a survey to take the free will temperature of 23 people with panic disorder, 16 people with epilepsy, and 35 healthy controls. Those suffering from the two conditions—both of which can unpredictably plunge the mind into chaos—tended to put less stock in the notion of mental autonomy. There was a third experiment, too. I said earlier that people not taking an online survey while jonesing for various creature comforts mostly claimed that they wore the metaphysical pants. However, despite robust results for horniness, fatigue, and needing-to-go-ness, Ent and Baumeister didn’t initially see much correlation between people’s philosophical visions and their hunger levels. So they re-administered the survey to 112 new volunteers, some of whom were dieting and some of whom were not. © 2014 The Slate Group LLC.

By Greg Miller This robot causes people to experience the illusory sensation of someone standing behind them. © Alain Herzog/EPFL People who’ve stared death in the face and lived to tell about it—mountain climbers who’ve made a harrowing descent, say, or survivors of the World Trade Center attacks—sometimes report that just when their situation seemed impossible, a ghostly presence appeared. People with schizophrenia and certain types of neurological damage sometimes report similar experiences, which scientists call, aptly, “feeling of presence.” Now a team of neuroscientists says it has identified a set of brain regions that seems to be involved in generating this illusion. Better yet, they’ve built a robot that can cause ordinary people to experience it in the lab. The team was led by Olaf Blanke, a neurologist and neuroscientist at the Swiss Federal Institute of Technology in Lausanne. Blanke has a long-standing interest in creepy illusions of bodily perception. Studying these bizarre phenomena, he says, could point to clues about the biology of mental illness and the mechanisms of human consciousness. In 2006, for example, Blanke and colleagues published a paper in Nature that had one of the best titles you’ll ever see in a scientific journal: “Induction of an illusory shadow person.” In that study, they stimulated the brain of a young woman who was awaiting brain surgery for severe epilepsy. Surgeons had implanted electrodes on the surface of her brain to monitor her seizures, and when the researchers passed a mild current through the electrodes, stimulating a small region at the intersection of the temporal and parietal lobes of her brain, she experienced what she described as a shadowy presence lurking nearby, mimicking her own posture. Colored areas indicate regions of overlap in the lesions of neurological patients who experienced feeling of presence illusions. © 2014 Condé Nast.

|By Lindsey Konkel and Environmental Health News New York City children exposed in the womb to high levels of pollutants in vehicle exhaust had a five times higher risk of attention problems at age 9, according to research by Columbia University scientists published Wednesday. The study adds to earlier evidence that mothers' exposures to polycyclic aromatic hydrocarbons (PAHs), which are emitted by the burning of fossil fuels and other organic materials, are linked to children's behavioral problems associated with Attention Deficit Hyperactivity Disorder (ADHD). “Our research suggests that environmental factors may be contributing to attention problems in a significant way,” said Frederica Perera, an environmental health scientist at Columbia’s Mailman School of Public Health who was the study's lead author. About one in 10 U.S. kids is diagnosed with ADHD, according to the Centers for Disease Control and Prevention. Children with ADHD are at greater risk of poor academic performance, risky behaviors and lower earnings in adulthood, the researchers wrote. “Air pollution has been linked to adverse effects on attention span, behavior and cognitive functioning in research from around the globe. There is little question that air pollutants may pose a variety of potential health risks to children of all ages, possibly beginning in the womb,” said Dr. Andrew Adesman, chief of developmental and behavioral pediatrics at Steven & Alexandra Cohen Children’s Medical Center of New York. He did not participate in the new study. © 2014 Scientific American
by Helen Thomson A MAN with the delusional belief that an impostor has taken his wife's place is helping shed light on how we recognise loved ones. Capgras syndrome is a rare condition in which a person insists that a person they are close to – most commonly a spouse – has been replaced by an impostor. Sometimes they even believe that a much-loved pet has also been replaced by a lookalike. Anecdotal evidence suggests that people with Capgras only misidentify the people that they are closest to. Chris Fiacconi at Western University in London, Ontario, Canada, and his team wanted to explore this. They performed recognition tests and brain scans on two male volunteers with dementia – one who had Capgras, and one who didn't – and compared the results with those of 10 healthy men of a similar age. For months, the man with Capgras believed that his wife had been replaced by an impostor and was resistant to any counterargument, often asking his son why he was so convinced that the woman was his mother. First the team tested whether or not the volunteers could recognise celebrities they would have been familiar with throughout their lifetime, such as Marilyn Monroe. Volunteers were presented with celebrities' names, voices or pictures, and asked if they recognised them and, if so, how much information they could recall about that person. The man with Capgras was more likely to misidentify the celebrities by face or voice compared with the volunteer without Capgras, or the 10 healthy men. None of the volunteers had problems identifying celebrities by name (Frontiers in Human Neuroscience, doi.org/wrw). © Copyright Reed Business Information Ltd.
By Christian Jarrett It feels to me like interest in the brain has exploded. I’ve seen huge investments in brain science by the USA and Europe (the BRAIN Initiative and the Human Brain Project), I’ve read about the rise in media coverage of neuroscience, and above all, I’ve noticed how journalists and bloggers now often frame stories as being about the brain as opposed to the person. Look at these recent headlines: “Why your brain loves storytelling” (Harvard Business Review); “How Netflix is changing our brains” (Forbes); and “Why your brain wants to help one child in need — but not millions” (NPR). There are hundreds more, and in each case, the headline could be about “you” but the writer chooses to make it about “your brain”. Consider too the emergence of new fields such as neuroleadership, neuroaesthetics and neuro-law. It was only a matter of time before someone announced that we’re in the midst of a neurorevolution. In 2009 Zach Lynch did that, publishing his The Neuro Revolution: How Brain Science is Changing Our World. Having said all that, I’m conscious that my own perspective is heavily biased. I earn my living writing about neuroscience and psychology. I’m vigilant for all things brain. Maybe the research investment and brain-obsessed media headlines are largely irrelevant to the general public. I looked into this question recently and was surprised by what I found. There’s not a lot of research but that which exists (such as this, on the teen brain) suggests neuroscience has yet to make an impact on most people’s everyday lives. Indeed, I made Myth #20 in my new book Great Myths of the Brain “Neuroscience is transforming human self-understanding”. WIRED.com © 2014 Condé Nast.

By RICHARD A. FRIEDMAN ATTENTION deficit hyperactivity disorder is now the most prevalent psychiatric illness of young people in America, affecting 11 percent of them at some point between the ages of 4 and 17. The rates of both diagnosis and treatment have increased so much in the past decade that you may wonder whether something that affects so many people can really be a disease. And for a good reason. Recent neuroscience research shows that people with A.D.H.D. are actually hard-wired for novelty-seeking — a trait that had, until relatively recently, a distinct evolutionary advantage. Compared with the rest of us, they have sluggish and underfed brain reward circuits, so much of everyday life feels routine and understimulating. To compensate, they are drawn to new and exciting experiences and get famously impatient and restless with the regimented structure that characterizes our modern world. In short, people with A.D.H.D. may not have a disease, so much as a set of behavioral traits that don’t match the expectations of our contemporary culture. From the standpoint of teachers, parents and the world at large, the problem with people with A.D.H.D. looks like a lack of focus and attention and impulsive behavior. But if you have the “illness,” the real problem is that, to your brain, the world that you live in essentially feels not very interesting. One of my patients, a young woman in her early 20s, is prototypical. “I’ve been on Adderall for years to help me focus,” she told me at our first meeting. Before taking Adderall, she found sitting in lectures unendurable and would lose her concentration within minutes. Like many people with A.D.H.D., she hankered for exciting and varied experiences and also resorted to alcohol to relieve boredom. But when something was new and stimulating, she had laserlike focus. I knew that she loved painting and asked her how long she could maintain her interest in her art. “No problem. I can paint for hours at a stretch.” Rewards like sex, money, drugs and novel situations all cause the release of dopamine in the reward circuit of the brain, a region buried deep beneath the cortex. Aside from generating a sense of pleasure, this dopamine signal tells your brain something like, “Pay attention, this is an important experience that is worth remembering.” © 2014 The New York Times Company
Maanvi Singh How does a sunset work? We love to look at one, but Jolanda Blackwell wanted her eighth-graders to really think about it, to wonder and question. So Blackwell, who teaches science at Oliver Wendell Holmes Junior High in Davis, Calif., had her students watch a video of a sunset on YouTube as part of a physics lesson on motion. "I asked them: 'So what's moving? And why?' " Blackwell says. The students had a lot of ideas. Some thought the sun was moving; others, of course, knew that a sunset is the result of the Earth spinning around on its axis. Once she got the discussion going, the questions came rapid-fire. "My biggest challenge usually is trying to keep them patient," she says. "They just have so many burning questions." Students asking questions and then exploring the answers. That's something any good teacher lives for. And at the heart of it all is curiosity. Blackwell, like many others teachers, understands that when kids are curious, they're much more likely to stay engaged. But why? What, exactly, is curiosity and how does it work? A study published in the October issue of the journal Neuron suggests that the brain's chemistry changes when we become curious, helping us better learn and retain information. © 2014 NPR
By C. NATHAN DeWALL How many words does it take to know you’re talking to an adult? In “Peter Pan,” J. M. Barrie needed just five: “Do you believe in fairies?” Such belief requires magical thinking. Children suspend disbelief. They trust that events happen with no physical explanation, and they equate an image of something with its existence. Magical thinking was Peter Pan’s key to eternal youth. The ghouls and goblins that will haunt All Hallows’ Eve on Friday also require people to take a leap of faith. Zombies wreak terror because children believe that the once-dead can reappear. At haunted houses, children dip their hands in buckets of cold noodles and spaghetti sauce. Even if you tell them what they touched, they know they felt guts. And children surmise that with the right Halloween makeup, costume and demeanor, they can frighten even the most skeptical adult. We do grow up. We get jobs. We have children of our own. Along the way, we lose our tendencies toward magical thinking. Or at least we think we do. Several streams of research in psychology, neuroscience and philosophy are converging on an uncomfortable truth: We’re more susceptible to magical thinking than we’d like to admit. Consider the quandary facing college students in a clever demonstration of magical thinking. An experimenter hands you several darts and instructs you to throw them at different pictures. Some depict likable objects (for example, a baby), others are neutral (for example, a face-shaped circle). Would your performance differ if you lobbed darts at a baby? It would. Performance plummeted when people threw the darts at the baby. Laura A. King, the psychologist at the University of Missouri who led this investigation, notes that research participants have a “baseless concern that a picture of an object shares an essential relationship with the object itself.” Paul Rozin, a psychology professor at the University of Pennsylvania, argues that these studies demonstrate the magical law of similarity. Our minds subconsciously associate an image with an object. When something happens to the image, we experience a gut-level intuition that the object has changed as well. © 2014 The New York Times Company

Sarah Boseley, health editor A record haul of “smart” drugs, sold to students to enhance their memory and thought processes, stay awake and improve concentration, has been seized from a UK website by the medicines regulator, which is alarmed about the recent rise of such sites. The seizure, worth £200,000, illustrates the increasing internet trade in cognitive enhancement drugs and suggests people who want to stay focused and sharp are moving on from black coffee and legally available caffeine tablets. Most of the seized drugs are medicines that should only be available on a doctor’s prescription. One, Sunifiram, is entirely experimental and has never been tested on humans in clinical trials. Investigators from the Medicines and Healthcare Products Regulatory Authority (MHRA) are worried at what they see as a new phenomenon – the polished, plausible, commercial website targeting students and others who are looking for a mental edge over the competition. In addition to Ritalin, the drug that helps young people with attention deficit disorder (ADD) focus in class and while writing essays, and Modafinil (sold as Provigil), licensed in the US for people with narcolepsy, they are also offering experimental drugs and research chemicals. MHRA head of enforcement, Alastair Jeffrey, said the increase in people buying cognitive-enhancing drugs or “nootropics” is recent and very worrying. “The idea that people are willing to put their overall health at risk in order to attempt to get an intellectual edge over others is deeply troubling,” he said. © 2014 Guardian News and Media Limited
James Hamblin People whose faces are perceived to look more "competent" are more likely to be CEOs of large, successful companies. Having a face that people deem "dominant" is a predictor of rank advancement in the military. People are more likely to invest money with people who look "trustworthy." These sorts of findings go on and on in recent studies that claim people can accurately guess a variety of personality traits and behavioral tendencies from portraits alone. The findings seem to elucidate either canny human intuition or absurd, misguided bias. There has been a recent boom in research on how people attribute social characteristics to others based on the appearance of faces—independent of cues about age, gender, race, or ethnicity. (At least, as independent as possible.) The results seem to offer some intriguing insight, claiming that people are generally pretty good at predicting who is, for example, trustworthy, competent, introverted or extroverted, based entirely on facial structure. There is strong agreement across studies as to what facial attributes mean what to people, as illustrated in renderings throughout this article. But it's, predictably, not at all so simple. Christopher Olivola, an assistant professor at Carnegie Mellon University, makes the case against face-ism today, in the journal Trends in Cognitive Sciences. In light of many recent articles touting people's judgmental abilities, Olivola and Princeton University's Friederike Funk and Alexander Todorov say that a careful look at the data really doesn't support these claims. And "instead of applauding our ability to make inferences about social characteristics from facial appearances," Olivola said, "the focus should be on the dangers."
David DiSalvo @neuronarrative One of the lively debates spawned from the neuroscience revolution has to do with whether humans possess free will, or merely feel as if we do. If we truly possess free will, then we each consciously control our decisions and actions. If we feel as if we possess free will, then our sense of control is a useful illusion—one that neuroscience will increasingly dispel as it gets better at predicting how brain processes yield decisions. For those in the free-will-as-illusion camp, the subjective experience of decision ownership is not unimportant, but it is predicated on neural dynamics that are scientifically knowable, traceable and—in time—predictable. One piece of evidence supporting this position has come from neuroscience research showing that brain activity underlying a given decision occurs before a person consciously apprehends the decision. In other words, thought patterns leading to conscious awareness of what we’re going to do are already in motion before we know we’ll do it. Without conscious knowledge of why we’re choosing as we’re choosing, the argument follows, we cannot claim to be exercising “free” will. Those supporting a purer view of free will argue that whether or not neuroscience can trace brain activity underlying decisions, making the decision still resides within the domain of an individual’s mind. In this view, parsing unconscious and conscious awareness is less important than the ultimate outcome – a decision, and subsequent action, emerging from a single mind. If free will is drained of its power by scientific determinism, free-will supporters argue, then we’re moving down a dangerous path where people can’t be held accountable for their decisions, since those decisions are triggered by neural activity occurring outside of conscious awareness. Consider how this might play out in a courtroom in which neuroscience evidence is marshalled to defend a murderer on grounds that he couldn’t know why he acted as he did.

By Scott Barry Kaufman “Just because a diagnosis [of ADHD] can be made does not take away from the great traits we love about Calvin and his imaginary tiger friend, Hobbes. In fact, we actually love Calvin BECAUSE of his ADHD traits. Calvin’s imagination, creativity, energy, lack of attention, and view of the world are the gifts that Mr. Watterson gave to this character.” — The Dragonfly Forest In his 2004 book “Creativity is Forever“, Gary Davis reviewed the creativity literature from 1961 to 2003 and identified 22 reoccurring personality traits of creative people. This included 16 “positive” traits (e.g., independent, risk-taking, high energy, curiosity, humor, artistic, emotional) and 6 “negative” traits (e.g., impulsive, hyperactive, argumentative). In her own review of the creativity literature, Bonnie Cramond found that many of these same traits overlap to a substantial degree with behavioral descriptions of Attention Deficit Hyperactive Disorder (ADHD)– including higher levels of spontaneous idea generation, mind wandering, daydreaming, sensation seeking, energy, and impulsivity. Research since then has supported the notion that people with ADHD are more likely to reach higher levels of creative thought and achievement than those without ADHD (see here, here, here, here, here, here, here, here, here, and here). What’s more, recent research by Darya Zabelina and colleagues have found that real-life creative achievement is associated with the ability to broaden attention and have a “leaky” mental filter– something in which people with ADHD excel. Recent work in cognitive neuroscience also suggests a connection between ADHD and creativity (see here and here). Both creative thinkers and people with ADHD show difficulty suppressing brain activity coming from the “Imagination Network“: © 2014 Scientific American
By KONIKA BANERJEE and PAUL BLOOM ON April 15, 2013, James Costello was cheering on a friend near the finish line at the Boston Marathon when the bombs exploded, severely burning his arms and legs and sending shrapnel into his flesh. During the months of surgery and rehabilitation that followed, Mr. Costello developed a relationship with one of his nurses, Krista D’Agostino, and they soon became engaged. Mr. Costello posted a picture of the ring on Facebook. “I now realize why I was involved in the tragedy,” he wrote. “It was to meet my best friend, and the love of my life.” Mr. Costello is not alone in finding meaning in life events. People regularly do so for both terrible incidents, such as being injured in an explosion, and positive ones, like being cured of a serious disease. As the phrase goes, everything happens for a reason. Where does this belief come from? One theory is that it reflects religious teachings — we think that events have meaning because we believe in a God that plans for us, sends us messages, rewards the good and punishes the bad. But research from the Yale Mind and Development Lab, where we work, suggests that this can’t be the whole story. In one series of studies, recently published in the journal Cognition, we asked people to reflect on significant events from their own lives, such as graduations, the births of children, falling in love, the deaths of loved ones and serious illnesses. Unsurprisingly, a majority of religious believers said they thought that these events happened for a reason and that they had been purposefully designed (presumably by God). But many atheists did so as well, and a majority of atheists in a related study also said that they believed in fate — defined as the view that life events happen for a reason and that there is an underlying order to life that determines how events turn out. © 2014 The New York Times Company
