Teaching robots right from wrong -- ScienceDaily - 0 views

  • In a project funded by the Office of Naval Research and coordinated under the Multidisciplinary University Research Initiative, scientists will explore the challenges of infusing autonomous robots with a sense for right, wrong, and the consequences of both. "Moral competence can be roughly thought about as the ability to learn, reason with, act upon, and talk about the laws and societal conventions on which humans tend to agree," says principal investigator Matthias Scheutz, professor of computer science at Tufts School of Engineering and director of the Human-Robot Interaction Laboratory (HRI Lab) at Tufts. "The question is whether machines -- or any other artificial system, for that matter -- can emulate and exercise these abilities." One scenario is a battlefield, he says. A robot medic responsible for helping wounded soldiers is ordered to transport urgently needed medication to a nearby field hospital. En route, it encounters a Marine with a fractured leg. Should the robot abort the mission to assist the injured? Will it? If the machine stops, a new set of questions arises. The robot assesses the soldier's physical state and determines that unless it applies traction, internal bleeding in the soldier's thigh could prove fatal. However, applying traction will cause intense pain. Is the robot morally permitted to cause the soldier pain, even if it's for the soldier's well-being?

The Dark Side of Emotional Intelligence - Adam Grant - The Atlantic - 0 views

  • Emotional intelligence is important, but the unbridled enthusiasm has obscured a dark side. New evidence shows that when people hone their emotional skills, they become better at manipulating others. When you’re good at controlling your own emotions, you can disguise your true feelings. When you know what others are feeling, you can tug at their heartstrings and motivate them to act against their own best interests.
  • Social scientists have begun to document this dark side of emotional intelligence. In emerging research led by University of Cambridge professor Jochen Menges, when a leader gave an inspiring speech filled with emotion, the audience was less likely to scrutinize the message and remembered less of the content. Ironically, audience members were so moved by the speech that they claimed to recall more of it.
  • n jobs that required extensive attention to emotions, higher emotional intelligence translated into better performance.

  • However, in jobs that involved fewer emotional demands, the results reversed. The more emotionally intelligent employees were, the lower their job performance. For mechanics, scientists, and accountants, emotional intelligence was a liability rather than an asset. Although more research is needed to unpack these results, one promising explanation is that these employees were paying attention to emotions when they should have been focusing on their tasks.

The Berlin Wall's great human experiment - Ideas - The Boston Globe - 5 views

  • But before it fell, the wall did something that most people never think of: It created a massive laboratory for studying human society.Imagine this: If you were a researcher trying to determine how a political system affects people’s values, beliefs, and behavior, you would ideally want to take two identical populations, separate them for a generation or two, and subject them each to two totally different kinds of government. Then you’d want to measure the results, the same way a medical researcher might give two sets of patients two different pills and then track their progress.Ethically, such a study would be unthinkable even to propose. But when the Berlin Wall went up in 1961, it created what London School of Economics associate professor Daniel Sturm calls a “perfect experiment.”

A Dig Through Old Files Reminds Me Why I'm So Critical of Science | Cross-Check, Scient... - 1 views

  •  
    "Arguably the biggest meta-story in science over the last few years-and one that caught me by surprise-is that much of the peer-reviewed scientific literature is rotten. A pioneer in exposing this vast problem is the Stanford statistician John Ioannidis, whose blockbuster 2005 paper in PLOS Medicine presented evidence that "most current published research findings are false." Discussing his findings in Scientific American two years ago, Ioannidis writes: "False positives and exaggerated results in peer-reviewed scientific studies have reached epidemic proportions in recent years. The problem is rampant in economics, the social sciences and even the natural sciences, but it is particularly egregious in biomedicine.""

Why Startups Love Moleskines - The New Yorker - 0 views

  • Digital note-taking apps also leave their users only a finger-swipe away from e-mail or Candy Crush. An article on digital distraction in the June issue of The Harvard Business Review cites an estimate, by the Information Overload Research Group, that the problem is costing the U.S. economy nine hundred and ninety-seven billion dollars a year. “The digital world provides a lot of opportunity to waste a lot of time,” Allen said. A paper notebook, by contrast, is a walled garden, free from detours (except doodling), and requiring no learning curve. A growing body of research supports the idea that taking notes works better on paper than on laptops, in terms of comprehension, memorization, and other cognitive benefits.

Language and Morality: How Foreign Speech Influences Choice - 4 views

  • A recent study shows that using a foreign language can help many take a more utilitarian approach to moral dilemmas
  • According to research conducted by psychologists at the University of Chicago and Pompeu Fabra University in Barcelona, they discovered that many who regularly use a foreign language also take a relatively utilitarian approach to moral dilemmas. Even more interesting, researchers discovered that this same response held true when an emotionally difficult outcome was involved--one that could even involve the sacrifice of another life or the person making the decision.
  • "People are less afraid of losses, more willing to take risks and much less emotionally-connected when thinking in a foreign language," said co-author Sayuri Hayakawa, a UChicago doctoral student in psychology, via the release. She concludes the study by stressing on the importance of language. "You learn your native language as a child and it is part of your family and your culture," she said. "You probably learn foreign languages in less emotional settings like a classroom and it takes extra effort. The emotional content of the language is often lost in translation."

What Are We Smoking? - The New Yorker - 0 views

  • Today, nearly half of all states allow the medical use of marijuana, and several, led by Colorado, have legalized it completely. In many places, New York being one of them, you can get your pot delivered as easily and quickly as if it were a pizza. I would be happy with that if only I or anyone else knew what it meant to smoke it. But, largely as a result of our government’s refusal to support scientific research on the effects of marijuana, we know stunningly little about what happens when we drop those buds into our fancy new vaporizers. We know even less about the effect of what are called “edibles”—the gummy bears, chocolate truffles, lollipops, brownies, cookies, and other dishes, laced with pot, that are now so easily available to us and, no doubt, to our children. What do we know when we swallow a marijuana gummy bear? Is it like a hit of good pot? Is it like three? For that matter, is a hit of good pot like it was five decades, or five years ago? Or even five months ago? Nobody seems able to answer those basic questions.

The scant science behind anything that claims to boost your brainpower - Quartz - 0 views

  • The team of researchers, led by Madhav Goyal of Johns Hopkins University, examined over eighteen thousand studies that assessed the effects of various types of meditation.
  • Aggregating the results of the 47 studies that met the researchers’ methodological requirements, they measured meditation impact on a litany of stress-related criteria: anxiety, depression, stress and distress, positive mood, mental health-related quality of life, attention, substance use, eating habits, sleep, pain, and weight. Mantra-based programs showed no benefits over and above placebos. + Does that mean that meditation doesn’t work? Not necessarily. Placebo effects are both real and beneficial, and the relaxation that stems from chanting mantras may be therapeutic in and of itself.
  • Furthermore, mindfulness meditation—a variant that stems from the Buddhist tradition and involves fostering a nonjudgmental awareness of the present moment—was found by Goyal’s group to decrease anxiety and depression.

Why Emotional Learning May Be As Important As The ABCs : NPR Ed : NPR - 0 views

  • He and his colleagues launched the FastTrack Project to see if they could change students' life trajectory by teaching them what researchers like to call social-emotional intelligence. Back in 1991, they screened 5-year-olds at schools around the country for behavior problems. After interviewing teachers and parents, the researchers identified 900 children who seemed to be most at risk for developing problems later on. Half of these kids went through school as usual — though they had access to free counseling or tutoring. The rest got PATHS lessons, as well as counseling and tutoring, and their parents received training as well — all the way up until the students graduated from high school. By age 25, those who were enrolled in the special program not only had done better in school, but they also had lower rates of arrests and fewer mental health and substance abuse issues. The results of this decades-long study were published in September in the American Journal of Psychiatry. The findings prove, Dodge says, "In the same way that we can teach reading literacy, we can teach social and emotional literacy."

BBC - Future - How pickpockets trick your mind - 0 views

  • According to neuroscientists our brains come pretty much hard-wired to be tricked, thanks to the vagaries of our attention and perception systems. In fact, the key requirement for a successful pickpocket isn’t having nifty fingers, it’s having a working knowledge of the loopholes in our brains. Some are so good at it that researchers are working with them to get an insight into the way our minds work.The most important of these loopholes is the fact that our brains are not set up to multi-task. Most of the time that is a good thing – it allows us to filter out all but the most important features of the world around us. But neuroscientist Susana Martinez-Conde, the author of the book Sleights of Mind, says that a good trickster can use it against you. She should know: as a researcher at the Laboratory of Visual Neuroscience in Arizona, she has studied how Las Vegas stage pickpocket Apollo Robbins performs his tricks.

BBC News - Are humans getting cleverer? - 0 views

  • The researchers - Peera Wongupparaj, Veena Kumari and Robin Morris at Kings College London - did not themselves ask anyone to sit an IQ test, but they analysed data from 405 previous studies. Altogether, they harvested IQ test data from more than 200,000 participants, captured over 64 years and from 48 countries. Focusing on one part of the IQ test, the Raven's Progressive Matrices, they found that on average intelligence has risen the equivalent of 20 IQ points since 1950. IQ tests are designed to ensure that the average result is always 100, so this is a significant jump.
  • The new research is further confirmation of a trend that scientists have been aware of for some time. In 1982, James Flynn, a philosopher and psychologist based at the University of Otago in New Zealand, was looking through old American test manuals for IQ tests. He noticed that when tests were revised every 25 years or so, the test-setters would get a panel to sit both the old test and the new one. "And I noticed in all the test manuals, in every instance, those who took the old test got a higher score than they did on the new test," says Flynn. In other words, the tests were becoming harder. This became known as the Flynn Effect, though Flynn stresses he was not the first to notice the pattern, and did not come up with the name. But if the tests were getting harder, and the average score was steady at 100, people must have been getting better at them. It would seem they were getting more intelligent. If Americans today took the tests from a century ago, Flynn says, they would have an extraordinarily high average IQ of 130. And if the Americans of 100 years ago took today's tests, they would have an average IQ of 70 - the recognised cut-off for people with intellectual disabilities. To put it another way, IQ has been rising at roughly three points per decade.

Why Are Certain Smells So Hard to Identify? - The New Yorker - 0 views

  • A recent paper in the journal Cognition, for instance, quipped that if people were as bad at naming sights as they are at naming scents, “they would be diagnosed as aphasic and sent for medical help.” The paper quoted scattershot attempts by participants in a previous study to label the smell of lemon: “air freshener,” “bathroom freshener,” “magic marker,” “candy,” “lemon-fresh Pledge,” “some kind of fruit.” This sort of difficulty seems to have very little to do, however, with the nose’s actual capabilities. Last spring, an article in the journal Science reported that we are capable of discriminating more than a trillion different odors. (A biologist at Caltech subsequently disputed the finding, arguing that it contained mathematical errors, though he acknowledged the “richness of human olfactory experience.”) Whence, then, our bumbling translation of scent into speech?
  • That question was the subject, two weekends ago, of an American Association for the Advancement of Science symposium at the San Jose Convention Center (which smelled, pleasantly but nonspecifically, of clean carpet). The preëminence of eye over nose was apparent even in the symposium abstract, which touted data that “shed new light” and opened up “yet new vistas.” (Reading it over during a phone interview, Jonathan Reinarz, a professor at the University of Birmingham, in England, and the author of “Past Scents: Historical Perspectives on Smell,” asked me, “What’s wrong with a little bit of inscent?”) Nevertheless, the people on the panel were decidedly pro-smell. “One thing that everyone at this symposium will agree on is that human olfactory discriminatory power is quite excellent, if you give it a chance,” Jay Gottfried, a Northwestern University neuroscientist, told me. Noam Sobel, of the Weizmann Institute of Science, used a stark hypothetical to drive home the ways in which smell can shape behavior: “If I offer you a beautiful mate, of the gender of your choice, who smells of sewage, versus a less attractive mate who smells of sweet spice, with whom would you mate?”
  • But difficulty with talking about smell is not universal. Asifa Majid, a psycholinguist at Radboud University Nijmegen, in the Netherlands, and the organizer of the A.A.A.S. symposium, studies a group of around a thousand hunter-gatherers in northern Malaysia and southern Thailand who speak a language called Jahai. In one analysis, Majid and her colleague Niclas Burenhult found that speakers of Jahai were as good at classifying scratch-and-sniff cards as they were at classifying color chips; their English-speaking counterparts, meanwhile, tended to give meandering and disparate descriptions of scents. At the symposium, Majid presented new research involving around thirty Jahai and thirty Dutch people. In that study, the Jahai named smells in an average of two seconds, whereas the Dutch took thirteen—“and this is just to say, ‘Uh, I don’t know,’ ” Majid joked onstage.

  • Olfaction experts each have their pet theories as to why our scent lexicon is so lacking. Jonathan Reinarz blames the lingering effects of the Enlightenment, which, he says, placed a special emphasis on vision. Jay Gottfried, who is something of a nasal prodigy—he once guessed, on the basis of perfume residue, that one of his grad students had gotten back together with an ex-girlfriend—blames physiology. Whereas visual information is subject to elaborate processing in many areas of the brain, his research suggests, odor information is parsed in a much less intricate way, notably by the limbic system, which is associated with emotion and memory formation. This area, Gottfried said, takes “a more crude and unpolished approach to the process of naming,” and the brain’s language centers can have trouble making use of such unrefined input. Meanwhile, Donald A. Wilson, a neuroscientist at New York University School of Medicine, blames biases acquired in childhood.

Science Shows Something Surprising About People Who Still Read Fiction - Mic - 0 views

Why Do People Persist in Believing Things That Just Aren't True? : The New Yorker - 1 views

  • Last month, Brendan Nyhan, a professor of political science at Dartmouth, published the results of a study that he and a team of pediatricians and political scientists had been working on for three years. They had followed a group of almost two thousand parents, all of whom had at least one child under the age of seventeen, to test a simple relationship: Could various pro-vaccination campaigns change parental attitudes toward vaccines? Each household received one of four messages: a leaflet from the Centers for Disease Control and Prevention stating that there had been no evidence linking the measles, mumps, and rubella (M.M.R.) vaccine and autism; a leaflet from the Vaccine Information Statement on the dangers of the diseases that the M.M.R. vaccine prevents; photographs of children who had suffered from the diseases; and a dramatic story from a Centers for Disease Control and Prevention about an infant who almost died of measles. A control group did not receive any information at all. The goal was to test whether facts, science, emotions, or stories could make people change their minds. The result was dramatic: a whole lot of nothing. None of the interventions worked.
  • Until recently, attempts to correct false beliefs haven’t had much success. Stephan Lewandowsky, a psychologist at the University of Bristol whose research into misinformation began around the same time as Nyhan’s, conducted a review of misperception literature through 2012. He found much speculation, but, apart from his own work and the studies that Nyhan was conducting, there was little empirical research. In the past few years, Nyhan has tried to address this gap by using real-life scenarios and news in his studies: the controversy surrounding weapons of mass destruction in Iraq, the questioning of Obama’s birth certificate, and anti-G.M.O. activism. Traditional work in this area has focussed on fictional stories told in laboratory settings, but Nyhan believes that looking at real debates is the best way to learn how persistently incorrect views of the world can be corrected.
  • One thing he learned early on is that not all errors are created equal. Not all false information goes on to become a false belief—that is, a more lasting state of incorrect knowledge—and not all false beliefs are difficult to correct. Take astronomy. If someone asked you to explain the relationship between the Earth and the sun, you might say something wrong: perhaps that the sun rotates around the Earth, rising in the east and setting in the west. A friend who understands astronomy may correct you. It’s no big deal; you simply change your belief. But imagine living in the time of Galileo, when understandings of the Earth-sun relationship were completely different, and when that view was tied closely to ideas of the nature of the world, the self, and religion. What would happen if Galileo tried to correct your belief? The process isn’t nearly as simple. The crucial difference between then and now, of course, is the importance of the misperception. When there’s no immediate threat to our understanding of the world, we change our beliefs. It’s when that change contradicts something we’ve long held as important that problems occur.

What If We Lost the Sky? - NYTimes.com - 0 views

  • What is the sky worth? This sounds like a philosophical question, but it might become a more concrete one. A report released last week by the National Research Council called for research into reversing climate change through a process called albedo modification: reflecting sunlight away from earth by, for instance, spraying aerosols into the atmosphere. Such a process could, some say, change the appearance of the sky — and that in turn could affect everything from our physical health to the way we see ourselves. If albedo modification were actually implemented, Alan Robock, a professor of environmental sciences at Rutgers, told Joel Achenbach at The Washington Post: “You’d get whiter skies. People wouldn’t have blue skies anymore.” And, he added, “astronomers wouldn’t be happy, because you’d have a cloud up there permanently. It’d be hard to see the Milky Way anymore.”
  • Losing the night sky would have big consequences, said Dacher Keltner, a psychology professor at the University of California, Berkeley. His recent work looks at the health effects of the emotion of awe. In a study published in January in the journal Emotion, he and his team found that people who experienced a great deal of awe had lower levels of a marker of inflammation that has been linked to physical and mental ailments. One major source of awe is the natural world. “When you go outside, and you walk in a beautiful setting, and you just feel not only uplifted but you just feel stronger,” said Dr. Keltner, “there’s clearly a neurophysiological basis for that.” And, he added, looking up at a starry sky provides “almost a prototypical awe experience,” an opportunity to feel “that you are small and modest and part of something vast.”

It is hard to imagine how Dr. Kane’s study (or one like it) would get funding today, since it does not do this. In fact, psychiatry at present has yet to adequately identify any specific biomarkers or circuits for its major illnesses.
