  • The adolescent population is highly vulnerable to driving under the influence of alcohol and social maladjustments due to an immature limbic system and prefrontal cortex.
  • Synaptic plasticity and the release of neurotransmitters may also be influenced by environmental neurotoxins and drugs of abuse including cigarettes, caffeine, and alcohol during adolescence.
  • Brain maturation during adolescence (ages 10–24 years) could be governed by several factors, as illustrated in Figure 1. It may be influenced by heredity and environment, prenatal and postnatal insult, nutritional status, sleep patterns, pharmacotherapy, and surgical interventions during early childhood.

  • During adolescence, the neurocircuitry strengthens and allows for multitasking, enhanced ability to solve problems, and the capability to process complex information. Furthermore, adolescent brain plasticity provides an opportunity to develop talents and lifelong interests; however, neurotoxic insult, trauma, chronic stress, drug abuse, and sedentary lifestyles may have a negative impact during this sensitive period of brain maturation

redshirting children development cognitive research

  • THIS fall, one in 11 kindergarten-age children in the United States will not be going to class. Parents of these children often delay school entry in an attempt to give them a leg up on peers, but this strategy is likely to be counterproductive.
  • Teachers may encourage redshirting because more mature children are easier to handle in the classroom and initially produce better test scores than their younger classmates.
  • This advantage fades by the end of elementary school, though, and disadvantages start to accumulate. In high school, redshirted children are less motivated and perform less well. By adulthood, they are no better off in wages or educational attainment — in fa

  • ct, their lifetime earnings are reduced by one year.
  • The benefits of being younger are even greater for those who skip a grade, an option available to many high-achieving children. Compared with nonskippers of similar talent and motivation, these youngsters pursue advanced degrees and enter professional school more often. Acceleration is a powerful intervention, with effects on achievement that are twice as large as programs for the gifted.
  • Parents who want to give their young children an academic advantage have a powerful tool: school itself. In a large-scale study at 26 Canadian elementary schools, first graders who were young for their year made considerably more progress in reading and math than kindergartners who were old for their year
  • The question we should ask instead is: What approach gives children the greatest opportunity to learn?
  • school makes children smarter.
  • These differences may come from the increased challenges of a demanding environment. Learning is maximized not by getting all the answers right, but by making errors and correcting them quickly.
  • Some children, especially boys, are slow to mature emotionally, a process that may be aided by the presence of older children.
  • The benefits of interacting with older children may extend to empathetic abilities. Empathy requires the ability to reason about the beliefs of others. This capacity relies on brain maturation, but it is also influenced by interactions with other children. Having an older (but not younger) sibling speeds the onset of this capacity in 3- to 5-year-olds. The acceleration is large: up to half a year per sibling.
  • children are not on a fixed trajectory but learn actively from teachers — and classmates. It matters very much who a child’s peers are. Redshirted children begin school with others who are a little further behind them. Because learning is social, the real winners in that situation are their classmates.
  • Richard Monari on 26 Sep 11
     
    I had never realized how incredibly critical the first years of a child's life were. This situation seems almost like a win-lose one; the younger children are more challenged and thus more prepared later on in life while the older ones will always be less motivated and all-around strong. Does this mean that we must set up our classrooms to have some students be statistically advantaged in life while others might potentially suffer? ARE WE GONNA DO THAT?!

  • Rosenstein belongs to a small but growing band of Silicon Valley heretics who complain about the rise of the so-called “attention economy”: an internet shaped around the demands of an advertising economy.
  • “It is very common,” Rosenstein says, “for humans to develop things with the best of intentions and for them to have unintended, negative consequences.”
  • most concerned about the psychological effects on people who, research shows, touch, swipe or tap their phone 2,617 times a day.
  • ...43 more annotations...
  • There is growing concern that as well as addicting users, technology is contributing toward so-called “continuous partial attention”, severely limiting people’s ability to focus, and possibly lowering IQ. One recent study showed that the mere presence of smartphones damages cognitive capacity – even when the device is turned off. “Everyone is distracted,” Rosenstein says. “All of the time.”
  • Drawing a straight line between addiction to social media and political earthquakes like Brexit and the rise of Donald Trump, they contend that digital forces have completely upended the political system and, left unchecked, could even render democracy as we know it obsolete.
  • Without irony, Eyal finished his talk with some personal tips for resisting the lure of technology. He told his audience he uses a Chrome extension, called DF YouTube, “which scrubs out a lot of those external triggers” he writes about in his book, and recommended an app called Pocket Points that “rewards you for staying off your phone when you need to focus”.
  • “One reason I think it is particularly important for us to talk about this now is that we may be the last generation that can remember life before,” Rosenstein says. It may or may not be relevant that Rosenstein, Pearlman and most of the tech insiders questioning today’s attention economy are in their 30s, members of the last generation that can remember a world in which telephones were plugged into walls.
  • One morning in April this year, designers, programmers and tech entrepreneurs from across the world gathered at a conference centre on the shore of the San Francisco Bay. They had each paid up to $1,700 to learn how to manipulate people into habitual use of their products, on a course curated by conference organiser Nir Eyal.
  • Eyal, 39, the author of Hooked: How to Build Habit-Forming Products, has spent several years consulting for the tech industry, teaching techniques he developed by closely studying how the Silicon Valley giants operate.
  • “The technologies we use have turned into compulsions, if not full-fledged addictions,” Eyal writes. “It’s the impulse to check a message notification. It’s the pull to visit YouTube, Facebook, or Twitter for just a few minutes, only to find yourself still tapping and scrolling an hour later.” None of this is an accident, he writes. It is all “just as their designers intended”
  • He explains the subtle psychological tricks that can be used to make people develop habits, such as varying the rewards people receive to create “a craving”, or exploiting negative emotions that can act as “triggers”. “Feelings of boredom, loneliness, frustration, confusion and indecisiveness often instigate a slight pain or irritation and prompt an almost instantaneous and often mindless action to quell the negative sensation,” Eyal writes.
  • The most seductive design, Harris explains, exploits the same psychological susceptibility that makes gambling so compulsive: variable rewards. When we tap those apps with red icons, we don’t know whether we’ll discover an interesting email, an avalanche of “likes”, or nothing at all. It is the possibility of disappointment that makes it so compulsive.
  • Finally, Eyal confided the lengths he goes to protect his own family. He has installed in his house an outlet timer connected to a router that cuts off access to the internet at a set time every day. “The idea is to remember that we are not powerless,” he said. “We are in control.
  • But are we? If the people who built these technologies are taking such radical steps to wean themselves free, can the rest of us reasonably be expected to exercise our free will?
  • Not according to Tristan Harris, a 33-year-old former Google employee turned vocal critic of the tech industry. “All of us are jacked into this system,” he says. “All of our minds can be hijacked. Our choices are not as free as we think they are.”
  • Harris, who has been branded “the closest thing Silicon Valley has to a conscience”, insists that billions of people have little choice over whether they use these now ubiquitous technologies, and are largely unaware of the invisible ways in which a small number of people in Silicon Valley are shaping their lives.
  • “I don’t know a more urgent problem than this,” Harris says. “It’s changing our democracy, and it’s changing our ability to have the conversations and relationships that we want with each other.” Harris went public – giving talks, writing papers, meeting lawmakers and campaigning for reform after three years struggling to effect change inside Google’s Mountain View headquarters.
  • He explored how LinkedIn exploits a need for social reciprocity to widen its network; how YouTube and Netflix autoplay videos and next episodes, depriving users of a choice about whether or not they want to keep watching; how Snapchat created its addictive Snapstreaks feature, encouraging near-constant communication between its mostly teenage users.
  • The techniques these companies use are not always generic: they can be algorithmically tailored to each person. An internal Facebook report leaked this year, for example, revealed that the company can identify when teens feel “insecure”, “worthless” and “need a confidence boost”. Such granular information, Harris adds, is “a perfect model of what buttons you can push in a particular person”.
  • Tech companies can exploit such vulnerabilities to keep people hooked; manipulating, for example, when people receive “likes” for their posts, ensuring they arrive when an individual is likely to feel vulnerable, or in need of approval, or maybe just bored. And the very same techniques can be sold to the highest bidder. “There’s no ethics,” he says. A company paying Facebook to use its levers of persuasion could be a car business targeting tailored advertisements to different types of users who want a new vehicle. Or it could be a Moscow-based troll farm seeking to turn voters in a swing county in Wisconsin.
  • It was Rosenstein’s colleague, Leah Pearlman, then a product manager at Facebook and on the team that created the Facebook “like”, who announced the feature in a 2009 blogpost. Now 35 and an illustrator, Pearlman confirmed via email that she, too, has grown disaffected with Facebook “likes” and other addictive feedback loops. She has installed a web browser plug-in to eradicate her Facebook news feed, and hired a social media manager to monitor her Facebook page so that she doesn’t have to.
  • Harris believes that tech companies never deliberately set out to make their products addictive. They were responding to the incentives of an advertising economy, experimenting with techniques that might capture people’s attention, even stumbling across highly effective design by accident.
  • It’s this that explains how the pull-to-refresh mechanism, whereby users swipe down, pause and wait to see what content appears, rapidly became one of the most addictive and ubiquitous design features in modern technology. “Each time you’re swiping down, it’s like a slot machine,” Harris says. “You don’t know what’s coming next. Sometimes it’s a beautiful photo. Sometimes it’s just an ad.”
  • The reality TV star’s campaign, he said, had heralded a watershed in which “the new, digitally supercharged dynamics of the attention economy have finally crossed a threshold and become manifest in the political realm”.
  • “Smartphones are useful tools,” he says. “But they’re addictive. Pull-to-refresh is addictive. Twitter is addictive. These are not good things. When I was working on them, it was not something I was mature enough to think about. I’m not saying I’m mature now, but I’m a little bit more mature, and I regret the downsides.”
  • All of it, he says, is reward-based behaviour that activates the brain’s dopamine pathways. He sometimes finds himself clicking on the red icons beside his apps “to make them go away”, but is conflicted about the ethics of exploiting people’s psychological vulnerabilities. “It is not inherently evil to bring people back to your product,” he says. “It’s capitalism.”
  • He identifies the advent of the smartphone as a turning point, raising the stakes in an arms race for people’s attention. “Facebook and Google assert with merit that they are giving users what they want,” McNamee says. “The same can be said about tobacco companies and drug dealers.”
  • McNamee chooses his words carefully. “The people who run Facebook and Google are good people, whose well-intentioned strategies have led to horrific unintended consequences,” he says. “The problem is that there is nothing the companies can do to address the harm unless they abandon their current advertising models.”
  • But how can Google and Facebook be forced to abandon the business models that have transformed them into two of the most profitable companies on the planet?
  • McNamee believes the companies he invested in should be subjected to greater regulation, including new anti-monopoly rules. In Washington, there is growing appetite, on both sides of the political divide, to rein in Silicon Valley. But McNamee worries the behemoths he helped build may already be too big to curtail.
  • Rosenstein, the Facebook “like” co-creator, believes there may be a case for state regulation of “psychologically manipulative advertising”, saying the moral impetus is comparable to taking action against fossil fuel or tobacco companies. “If we only care about profit maximisation,” he says, “we will go rapidly into dystopia.”
  • James Williams does not believe talk of dystopia is far-fetched. The ex-Google strategist who built the metrics system for the company’s global search advertising business, he has had a front-row view of an industry he describes as the “largest, most standardised and most centralised form of attentional control in human history”.
  • It is a journey that has led him to question whether democracy can survive the new technological age.
  • He says his epiphany came a few years ago, when he noticed he was surrounded by technology that was inhibiting him from concentrating on the things he wanted to focus on. “It was that kind of individual, existential realisation: what’s going on?” he says. “Isn’t technology supposed to be doing the complete opposite of this?
  • That discomfort was compounded during a moment at work, when he glanced at one of Google’s dashboards, a multicoloured display showing how much of people’s attention the company had commandeered for advertisers. “I realised: this is literally a million people that we’ve sort of nudged or persuaded to do this thing that they weren’t going to otherwise do,” he recalls.
  • Williams and Harris left Google around the same time, and co-founded an advocacy group, Time Well Spent, that seeks to build public momentum for a change in the way big tech companies think about design. Williams finds it hard to comprehend why this issue is not “on the front page of every newspaper every day.
  • “Eighty-seven percent of people wake up and go to sleep with their smartphones,” he says. The entire world now has a new prism through which to understand politics, and Williams worries the consequences are profound.
  • g. “The attention economy incentivises the design of technologies that grab our attention,” he says. “In so doing, it privileges our impulses over our intentions.”
  • That means privileging what is sensational over what is nuanced, appealing to emotion, anger and outrage. The news media is increasingly working in service to tech companies, Williams adds, and must play by the rules of the attention economy to “sensationalise, bait and entertain in order to survive”.
  • It is not just shady or bad actors who were exploiting the internet to change public opinion. The attention economy itself is set up to promote a phenomenon like Trump, who is masterly at grabbing and retaining the attention of supporters and critics alike, often by exploiting or creating outrage.
  • All of which has left Brichter, who has put his design work on the backburner while he focuses on building a house in New Jersey, questioning his legacy. “I’ve spent many hours and weeks and months and years thinking about whether anything I’ve done has made a net positive impact on society or humanity at all,” he says. He has blocked certain websites, turned off push notifications, restricted his use of the Telegram app to message only with his wife and two close friends, and tried to wean himself off Twitter. “I still waste time on it,” he confesses, “just reading stupid news I already know about.” He charges his phone in the kitchen, plugging it in at 7pm and not touching it until the next morning.
  • He stresses these dynamics are by no means isolated to the political right: they also play a role, he believes, in the unexpected popularity of leftwing politicians such as Bernie Sanders and Jeremy Corbyn, and the frequent outbreaks of internet outrage over issues that ignite fury among progressives.
  • All of which, Williams says, is not only distorting the way we view politics but, over time, may be changing the way we think, making us less rational and more impulsive. “We’ve habituated ourselves into a perpetual cognitive style of outrage, by internalising the dynamics of the medium,” he says.
  • It was another English science fiction writer, Aldous Huxley, who provided the more prescient observation when he warned that Orwellian-style coercion was less of a threat to democracy than the more subtle power of psychological manipulation, and “man’s almost infinite appetite for distractions”.
  • If the attention economy erodes our ability to remember, to reason, to make decisions for ourselves – faculties that are essential to self-governance – what hope is there for democracy itself?
  • “The dynamics of the attention economy are structurally set up to undermine the human will,” he says. “If politics is an expression of our human will, on individual and collective levels, then the attention economy is directly undermining the assumptions that democracy rests on.”

I found more and more people are tired with working regularly under the command of a boss. They want to get hold of themselves so they rather sign independent contracts and have a more flexible working time. However, this new form of economic is not mature since laws and regulations have not yet covered independent contractors. --Sissi (4/10/2017)

Every area stands on the same ground.” He pointed out that the flexible language options put all countries on an equal footing. For example, this year Macau was given its own setting, despite having a population of only 500,000.

But after more interactions, I understand how people in Taiwan think, and I become much more tolerant.”
  • Isaac Mao, a fellow at the Berkman Center for Internet and Society at Harvard University, attributed the maturation to the fact that more users are learning what Wikipedia is all about. “It all came back to the ‘five principles’ of Wikipedia, including authenticity, accuracy, neutral point of view and the use of references,” Mr. Mao said. “If there are disagreements over management and editing, people can engage in discussion based on these principles. Such atmosphere has been built up in the Chinese Wikipedia community gradually.”

shared by runlai_jiang on 15 Jan 18 - No Cached
  • The elephant seal (genus Mirounga) is the world's largest seal. There are two species of elephant seals, named according to the hemisphere in which they are found. Northern elephant seals (M. angustirostris) are found in coastal waters around Canada and Mexico, while southern elephant seals (M. leonina) are found off the coast of New Zealand, South Africa, and Argentina.
  • At sea, elephant seals range solo. They return to established breeding colonies each winter. Females become mature around 3 to 6 years of age, while males mature at 5 to 6 years.However, males need to achieve alpha status to mate, which is normally between the ages of 9 and 12. Males battle each other using body weight and teeth. While deaths are rare, scarring is common. An alpha male's harem ranges from 30 to 100 females. Other males wait on the edges of the colony, sometimes mating with females before the alpha male chases them away. Males remain on land over the winter to defend territory, meaning they don't leave to hunt.
  • Elephant seals have been hunted for their meat, fur, and blubber. Both northern and southern elephant seals were hunted to the brink of extinction. By 1892, most people believed the northern seals to be extinct. But in 1910, a single breeding colony was found around Guadalupe Island off Mexico's Baja California coast.

artificial intelligence science technology progression

shared by Emily Freilich on 08 Nov 13 - No Cached
  • Douglas Hofstadter, the Pulitzer Prize–winning author of Gödel, Escher, Bach, thinks we've lost sight of what artificial intelligence really means. His stubborn quest to replicate the human mind.
  • “If somebody meant by artificial intelligence the attempt to understand the mind, or to create something human-like, they might say—maybe they wouldn’t go this far—but they might say this is some of the only good work that’s ever been done
  • Their operating premise is simple: the mind is a very unusual piece of software, and the best way to understand how a piece of software works is to write it yourself.
  • ...43 more annotations...
  • “It depends on what you mean by artificial intelligence.”
  • Computers are flexible enough to model the strange evolved convolutions of our thought, and yet responsive only to precise instructions. So if the endeavor succeeds, it will be a double victory: we will finally come to know the exact mechanics of our selves—and we’ll have made intelligent machines.
  • Ever since he was about 14, when he found out that his youngest sister, Molly, couldn’t understand language, because she “had something deeply wrong with her brain” (her neurological condition probably dated from birth, and was never diagnosed), he had been quietly obsessed by the relation of mind to matter.
  • How could consciousness be physical? How could a few pounds of gray gelatin give rise to our very thoughts and selves?
  • Consciousness, Hofstadter wanted to say, emerged via just the same kind of “level-crossing feedback loop.”
  • In 1931, the Austrian-born logician Kurt Gödel had famously shown how a mathematical system could make statements not just about numbers but about the system itself.
  • But then AI changed, and Hofstadter didn’t change with it, and for that he all but disappeared.
  • By the early 1980s, the pressure was great enough that AI, which had begun as an endeavor to answer yes to Alan Turing’s famous question, “Can machines think?,” started to mature—or mutate, depending on your point of view—into a subfield of software engineering, driven by applications.
  • Take Deep Blue, the IBM supercomputer that bested the chess grandmaster Garry Kasparov. Deep Blue won by brute force.
  • Hofstadter wanted to ask: Why conquer a task if there’s no insight to be had from the victory? “Okay,” he says, “Deep Blue plays very good chess—so what? Does that tell you something about how we play chess? No. Does it tell you about how Kasparov envisions, understands a chessboard?”
  • AI started working when it ditched humans as a model, because it ditched them. That’s the thrust of the analogy: Airplanes don’t flap their wings; why should computers think?
  • It’s a compelling point. But it loses some bite when you consider what we want: a Google that knows, in the way a human would know, what you really mean when you search for something

  • analogy is “the fuel and fire of thinking,” the bread and butter of our daily mental lives.
  • there’s an analogy, a mental leap so stunningly complex that it’s a computational miracle: somehow your brain is able to strip any remark of the irrelevant surface details and extract its gist, its “skeletal essence,” and retrieve, from your own repertoire of ideas and experiences, the story or remark that best relates.
  • in Hofstadter’s telling, the story goes like this: when everybody else in AI started building products, he and his team, as his friend, the philosopher Daniel Dennett, wrote, “patiently, systematically, brilliantly,” way out of the light of day, chipped away at the real problem. “Very few people are interested in how human intelligence works,”

The idea behind Candide, a machine-translation system, was to start by admitting that the rules-based approach requires too deep an understanding of how language is produced; how semantics, syntax, and morphology work; and how words commingle in sentences and combine into paragraphs—to say nothing of understanding the ideas for which those words are merely conduits.
  • , Hofstadter directs the Fluid Analogies Research Group, affectionately known as FARG.
  • Parts of a program can be selectively isolated to see how it functions without them; parameters can be changed to see how performance improves or degrades. When the computer surprises you—whether by being especially creative or especially dim-witted—you can see exactly why.
  • When you read Fluid Concepts and Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought, which describes in detail this architecture and the logic and mechanics of the programs that use it, you wonder whether maybe Hofstadter got famous for the wrong book.
  • ut very few people, even admirers of GEB, know about the book or the programs it describes. And maybe that’s because FARG’s programs are almost ostentatiously impractical. Because they operate in tiny, seemingly childish “microdomains.” Because there is no task they perform better than a human.
  • “The entire effort of artificial intelligence is essentially a fight against computers’ rigidity.”
  • “Nobody is a very reliable guide concerning activities in their mind that are, by definition, subconscious,” he once wrote. “This is what makes vast collections of errors so important. In an isolated error, the mechanisms involved yield only slight traces of themselves; however, in a large collection, vast numbers of such slight traces exist, collectively adding up to strong evidence for (and against) particular mechanisms.
  • So IBM threw that approach out the window. What the developers did instead was brilliant, but so straightforward,
  • The technique is called “machine learning.” The goal is to make a device that takes an English sentence as input and spits out a French sentence
  • What you do is feed the machine English sentences whose French translations you already know. (Candide, for example, used 2.2 million pairs of sentences, mostly from the bilingual proceedings of Canadian parliamentary debates.)
  • By repeating this process with millions of pairs of sentences, you will gradually calibrate your machine, to the point where you’ll be able to enter a sentence whose translation you don’t know and get a reasonable resul
  • Google Translate team can be made up of people who don’t speak most of the languages their application translates. “It’s a bang-for-your-buck argument,” Estelle says. “You probably want to hire more engineers instead” of native speakers.
  • But the need to serve 1 billion customers has a way of forcing the company to trade understanding for expediency. You don’t have to push Google Translate very far to see the compromises its developers have made for coverage, and speed, and ease of engineering. Although Google Translate captures, in its way, the products of human intelligence, it isn’t intelligent itself.
  • “Did we sit down when we built Watson and try to model human cognition?” Dave Ferrucci, who led the Watson team at IBM, pauses for emphasis. “Absolutely not. We just tried to create a machine that could win at Jeopardy.”
  • For Ferrucci, the definition of intelligence is simple: it’s what a program can do. Deep Blue was intelligent because it could beat Garry Kasparov at chess. Watson was intelligent because it could beat Ken Jennings at Jeopardy.
  • “There’s a limited number of things you can do as an individual, and I think when you dedicate your life to something, you’ve got to ask yourself the question: To what end? And I think at some point I asked myself that question, and what it came out to was, I’m fascinated by how the human mind works, it would be fantastic to understand cognition, I love to read books on it, I love to get a grip on it”—he called Hofstadter’s work inspiring—“but where am I going to go with it? Really what I want to do is build computer systems that do something.
  • Peter Norvig, one of Google’s directors of research, echoes Ferrucci almost exactly. “I thought he was tackling a really hard problem,” he told me about Hofstadter’s work. “And I guess I wanted to do an easier problem.”
  • Of course, the folly of being above the fray is that you’re also not a part of it
  • As our machines get faster and ingest more data, we allow ourselves to be dumber. Instead of wrestling with our hardest problems in earnest, we can just plug in billions of examples of them.
  • Hofstadter hasn’t been to an artificial-intelligence conference in 30 years. “There’s no communication between me and these people,” he says of his AI peers. “None. Zero. I don’t want to talk to colleagues that I find very, very intransigent and hard to convince of anything
  • Everything from plate tectonics to evolution—all those ideas, someone had to fight for them, because people didn’t agree with those ideas.
  • Academia is not an environment where you just sit in your bath and have ideas and expect everyone to run around getting excited. It’s possible that in 50 years’ time we’ll say, ‘We really should have listened more to Doug Hofstadter.’ But it’s incumbent on every scientist to at least think about what is needed to get people to understand the ideas.”

Why You Will Marry the Wrong Person - The New York Times - 1 views

shared by Javier E on 29 May 16 - No Cached
  • IT’S one of the things we are most afraid might happen to us. We go to great lengths to avoid it. And yet we do it all the same: We marry the wrong person.
  • Partly, it’s because we have a bewildering array of problems that emerge when we try to get close to others. We seem normal only to those who don’t know us very well. In a wiser, more self-aware society than our own, a standard question on any early dinner date would be: “And how are you crazy?
  • Marriage ends up as a hopeful, generous, infinitely kind gamble taken by two people who don’t know yet who they are or who the other might be, binding themselves to a future they cannot conceive of and have carefully avoided investigating.
  • ...18 more annotations...
  • For most of recorded history, people married for logical sorts of reasons:
  • And from such reasonable marriages, there flowed loneliness, infidelity, abuse, hardness of heart and screams heard through the nursery doors
  • The marriage of reason was not, in hindsight, reasonable at all; it was often expedient, narrow-minded, snobbish and exploitative. That is why what has replaced it — the marriage of feeling — has largely been spared the need to account for itself
  • Finally, we marry to make a nice feeling permanent. We imagine that marriage will help us to bottle the joy we felt when the thought of proposing first came to us: Perhaps we were in Venice, on the lagoon, in a motorboat
  • But though we believe ourselves to be seeking happiness in marriage, it isn’t that simple. What we really seek is familiarity
  • We are looking to recreate, within our adult relationships, the feelings we knew so well in childhood. The love most of us will have tasted early on was often confused with other, more destructive dynamics: feelings of wanting to help an adult who was out of control, of being deprived of a parent’s warmth or scared of his anger, of not feeling secure enough to communicate our wishes.
  • How logical, then, that we should as grown-ups find ourselves rejecting certain candidates for marriage not because they are wrong but because they are too right — too balanced, mature, understanding and reliable — given that in our hearts, such rightness feels foreign. We marry the wrong people because we don’t associate being loved with feeling happy.
  • We make mistakes, too, because we are so lonely. No one can be in an optimal frame of mind to choose a partner when remaining single feels unbearable. We have to be wholly at peace with the prospect of many years of solitude in order to be appropriately picky
  • What matters in the marriage of feeling is that two people are drawn to each other by an overwhelming instinct and know in their hearts that it is right
  • marriage tends decisively to move us onto another, very different and more administrative plane, which perhaps unfolds in a suburban house, with a long commute and maddening children who kill the passion from which they emerged. The only ingredient in common is the partner. And that might have been the wrong ingredient to bottle.
  • The good news is that it doesn’t matter if we find we have married the wrong person.
  • We mustn’t abandon him or her, only the founding Romantic idea upon which the Western understanding of marriage has been based the last 250 years: that a perfect being exists who can meet all our needs and satisfy our every yearning.
  • WE need to swap the Romantic view for a tragic (and at points comedic) awareness that every human will frustrate, anger, annoy, madden and disappoint us — and we will (without any malice) do the same to them.
  • But none of this is unusual or grounds for divorce. Choosing whom to commit ourselves to is merely a case of identifying which particular variety of suffering we would most like to sacrifice ourselves for.
  • pessimism relieves the excessive imaginative pressure that our romantic culture places upon marriage. The failure of one particular partner to save us from our grief and melancholy is not an argument against that person and no sign that a union deserves to fail or be upgraded.
  • The person who is best suited to us is not the person who shares our every taste (he or she doesn’t exist), but the person who can negotiate differences in taste intelligently — the person who is good at disagreement.
  • Rather than some notional idea of perfect complementarity, it is the capacity to tolerate differences with generosity that is the true marker of the “not overly wrong” person
  • We should learn to accommodate ourselves to “wrongness,” striving always to adopt a more forgiving, humorous and kindly perspective on its multiple examples in ourselves and in our partners.

The Stereotypes About Math That Hold Americans Back - Jo Boaler - The Atlantic - 2 views

stereotypes math americans teaching

shared by grayton downing on 12 Nov 13 - No Cached
  • Mathematics education in the United States is broken. Open any newspaper and stories of math failure shout from the pages: low international rankings, widespread innumeracy in the general population, declines in math majors. Here’s the most shocking statistic I have read in recent years: 60 percent of the 13 million two-year college students in the U.S. are currently placed into remedial math courses; 75 percent of them fail or drop the courses and leave college with no degree.
  • We need to change the way we teach math in the U.S., and it is for this reason that I support the move to Common Core mathematics.
  • One of the reasons for these results is that mathematical problems that need thought, connection making, and even creativity are more engaging for students of all levels and for students of different genders, races, and socio-economic groups. This is not only shown by my research but by decades of research in our field.
  • ...10 more annotations...
  • ways of working are critical in mathematical work and when they are taught and valued, many more students contribute, leading to higher achievement
  • mathematics education we suffer from the widespread, distinctly American idea that only some people can be “math people.” This idea has been disproved by scientific research showing the incredible potential of the brain to grow and adapt. But the idea that math is hard, uninteresting, and accessible only to “nerds” persists. 
  • harsh stereotypical thinking—mathematics is for select racial groups and men. This thinking, as well as the teaching practices that go with it, have provided the perfect conditions for the creation of a math underclass.
  • online platform explaining research evidence on ability and the brain and on good mathematics teaching, for teachers and parents. The course had a transformative effect. It was taken by 40,000 people, and 95 percent said they would change their teaching or parenting as a result.
  • does not simply test a mathematical definition, as the first does. It requires that students visualize a triangle, use transformational geometry, consider whether different cases satisfy the mathematical definition, and then justify their thinking.
  • There is a good reason for this: Justification and reasoning are two of the acts that lie at the heart of mathematics. They are, in many ways, the essence of what mathematics is.  Scientists work to prove or disprove new theories by finding many cases that work or counter-examples that do not. Mathematicians, by contrast prove the validity of their propositions through justification and reasoning.
  • The young people who are successful in today’s workforce are those who can discuss and reason about productive mathematical pathways, and who can be wrong, but can trace back to errors and work to correct them.
  • American idea that those who are good at math are those who are fast. Speed is revered in math classes across the U.S., and students as young as five years old are given timed tests—even though these have been shown to create math anxiety in young children. Parents use flash cards and other devices to promote speed, not knowing that they are probably damaging their children’s mathematical development
  • The fact of being quick or slow isn't really relevant
  • gives more time for depth and exploration than the curricula it has replaced by removing some of the redundant methods students will never need or use.

    I found this article very interesting as it says that there are actually people who are afraid of living forever. As we see in history, almost every king is in search of ways to live forever. They are afraid of death because they don't know what they would become after death. It's like playing a game. When you work your role up to level one hundred, you will really cherish this role and don't want to have it dead. Eternity, whether to be alive or dead forever, is fearful when people think about it. The author related the reason with the logic of evolution and our development of front lobe in our brain. We are afraid of eternity because we are afraid of things that we cannot see. We cannot think of anything that's beyond eternity. It is a really terrifying feeling when you think deep about death, it feels like a blackhole that suck up your strength and hard to get out. --Sissi (2/24/2017)

App designers in touch with the latest trends in behavioral modification--nudging, the quantified self, and gamification--and good old-fashioned financial incentive manipulation, are tackling weakness of will. They're harnessing the power of payouts, cognitive biases, social networking, and biofeedback. The quantified self becomes the programmable self.

  • philosophers have had much to say about the enticing and seemingly inevitable dispersion of technological mental prosthetic that promise to substitute or enhance some of our motivational powers.
  • beyond the practical issues lie a constellation of central ethical concerns.

Let's call this hypothetical future Digital Willpower World and characterize the ethical traps we're about to discuss as potential general pitfalls
  • it is antithetical to the ideal of " resolute choice." Some may find the norm overly perfectionist, Spartan, or puritanical. However, it is not uncommon for folks to defend the idea that mature adults should strive to develop internal willpower strong enough to avoid external temptations, whatever they are, and wherever they are encountered.
  • In part, resolute choosing is prized out of concern for consistency, as some worry that lapse of willpower in any context indicates a generally weak character.
  • Fragmented selves behave one way while under the influence of digital willpower, but another when making decisions without such assistance. In these instances, inconsistent preferences are exhibited and we risk underestimating the extent of our technological dependency.
  • It simply means that when it comes to digital willpower, we should be on our guard to avoid confusing situational with integrated behaviors.
  • the problem of inauthenticity, a staple of the neuroethics debates, might arise. People might start asking themselves: Has the problem of fragmentation gone away only because devices are choreographing our behavior so powerfully that we are no longer in touch with our so-called real selves -- the selves who used to exist before Digital Willpower World was formed?
  • Infantalized subjects are morally lazy, quick to have others take responsibility for their welfare. They do not view the capacity to assume personal responsibility for selecting means and ends as a fundamental life goal that validates the effort required to remain committed to the ongoing project of maintaining willpower and self-control.
  • Michael Sandel's Atlantic essay, "The Case Against Perfection." He notes that technological enhancement can diminish people's sense of achievement when their accomplishments become attributable to human-technology systems and not an individual's use of human agency.
  • Borgmann worries that this environment, which habituates us to be on auto-pilot and delegate deliberation, threatens to harm the powers of reason, the most central component of willpower (according to the rationalist tradition).
  • In several books, including Technology and the Character of Contemporary Life, he expresses concern about technologies that seem to enhance willpower but only do so through distraction. Borgmann's paradigmatic example of the non-distracted, focally centered person is a serious runner. This person finds the practice of running maximally fulfilling, replete with the rewarding "flow" that can only comes when mind/body and means/ends are unified, while skill gets pushed to the limit.
  • Perhaps the very conception of a resolute self was flawed. What if, as psychologist Roy Baumeister suggests, willpower is more "staple of folk psychology" than real way of thinking about our brain processes?
  • novel approaches suggest the will is a flexible mesh of different capacities and cognitive mechanisms that can expand and contract, depending on the agent's particular setting and needs. Contrary to the traditional view that identifies the unified and cognitively transparent self as the source of willed actions, the new picture embraces a rather diffused, extended, and opaque self who is often guided by irrational trains of thought. What actually keeps the self and its will together are the given boundaries offered by biology, a coherent self narrative created by shared memories and experiences, and society. If this view of the will as an expa
  • nding and contracting system with porous and dynamic boundaries is correct, then it might seem that the new motivating technologies and devices can only increase our reach and further empower our willing selves.
  • "It's a mistake to think of the will as some interior faculty that belongs to an individual--the thing that pushes the motor control processes that cause my action," Gallagher says. "Rather, the will is both embodied and embedded: social and physical environment enhance or impoverish our ability to decide and carry out our intentions; often our intentions themselves are shaped by social and physical aspects of the environment."
  • It makes perfect sense to think of the will as something that can be supported or assisted by technology. Technologies, like environments and institutions can facilitate action or block it. Imagine I have the inclination to go to a concert. If I can get my ticket by pressing some buttons on my iPhone, I find myself going to the concert. If I have to fill out an application form and carry it to a location several miles away and wait in line to pick up my ticket, then forget it.
  • Perhaps the best way forward is to put a digital spin on the Socratic dictum of knowing myself and submit to the new freedom: the freedom of consuming digital willpower to guide me past the sirens.

The American Scholar: The Decline of the English Department - William M. Chace - 1 views

decline english department education university history

shared by Javier E on 14 Jun 12 - No Cached
  • The number of young men and women majoring in English has dropped dramatically; the same is true of philosophy, foreign languages, art history, and kindred fields, including history. As someone who has taught in four university English departments over the last 40 years, I am dismayed by this shift, as are my colleagues here and there across the land. And because it is probably irreversible, it is important to attempt to sort out the reasons—the many reasons—for what has happened.
  • English: from 7.6 percent of the majors to 3.9 percent
  • In one generation, then, the numbers of those majoring in the humanities dropped from a total of 30 percent to a total of less than 16 percent; during that same generation, business majors climbed from 14 percent to 22 percent.
  • ...23 more annotations...
  • History: from 18.5 percent to 10.7 percent
  • But the deeper explanation resides not in something that has happened to it, but in what it has done to itself. English has become less and less coherent as a discipline and, worse, has come near exhaustion as a scholarly pursuit.
  • The twin focus, then, was on the philological nature of the enterprise and the canon of great works to be studied in their historical evolution.
  • Studying English taught us how to write and think better, and to make articulate many of the inchoate impulses and confusions of our post-adolescent minds. We began to see, as we had not before, how such books could shape and refine our thinking. We began to understand why generations of people coming before us had kept them in libraries and bookstores and in classes such as ours. There was, we got to know, a tradition, a historical culture, that had been assembled around these books. Shakespeare had indeed made a difference—to people before us, now to us, and forever to the language of English-speaking people.
  • today there are stunning changes in the student population: there are more and more gifted and enterprising students coming from immigrant backgrounds, students with only slender connections to Western culture and to the assumption that the “great books” of England and the United States should enjoy a fixed centrality in the world. What was once the heart of the matter now seems provincial. Why throw yourself into a study of something not emblematic of the world but representative of a special national interest? As the campus reflects the cultural, racial, and religious complexities of the world around it, reading British and American literature looks more and more marginal. From a global perspective, the books look smaller.
  • With the cost of a college degree surging upward during the last quarter century—tuition itself increasing far beyond any measure of inflation—and with consequent growth in loan debt after graduation, parents have become anxious about the relative earning power of a humanities degree. Their college-age children doubtless share such anxiety. When college costs were lower, anxiety could be kept at bay. (Berkeley in the early ’60s cost me about $100 a year, about $700 in today’s dollars.)
  • Economists, chemists, biologists, psychologists, computer scientists, and almost everyone in the medical sciences win sponsored research, grants, and federal dollars. By and large, humanists don’t, and so they find themselves as direct employees of the institution, consuming money in salaries, pensions, and operating needs—not external money but institutional money.
  • These, then, are some of the external causes of the decline of English: the rise of public education; the relative youth and instability (despite its apparent mature solidity) of English as a discipline; the impact of money; and the pressures upon departments within the modern university to attract financial resources rather than simply use them up.
  • several of my colleagues around the country have called for a return to the aesthetic wellsprings of literature, the rock-solid fact, often neglected, that it can indeed amuse, delight, and educate. They urge the teaching of English, or French, or Russian literature, and the like, in terms of the intrinsic value of the works themselves, in all their range and multiplicity, as well-crafted and appealing artifacts of human wisdom. Second, we should redefine our own standards for granting tenure, placing more emphasis on the classroom and less on published research, and we should prepare to contest our decisions with administrators whose science-based model is not an appropriate means of evaluation.
  • “It may be that what has happened to the profession is not the consequence of social or philosophical changes, but simply the consequence of a tank now empty.” His homely metaphor pointed to the absence of genuinely new frontiers of knowledge and understanding for English professors to explore.
  • In this country and in England, the study of English literature began in the latter part of the 19th century as an exercise in the scientific pursuit of philological research, and those who taught it subscribed to the notion that literature was best understood as a product of language.
  • no one has come forward in years to assert that the study of English (or comparative literature or similar undertakings in other languages) is coherent, does have self-limiting boundaries, and can be described as this but not that.
  • to teach English today is to do, intellectually, what one pleases. No sense of duty remains toward works of English or American literature; amateur sociology or anthropology or philosophy or comic books or studies of trauma among soldiers or survivors of the Holocaust will do. You need not even believe that works of literature have intelligible meaning; you can announce that they bear no relationship at all to the world beyond the text.
  • With everything on the table, and with foundational principles abandoned, everyone is free, in the classroom or in prose, to exercise intellectual laissez-faire in the largest possible way—I won’t interfere with what you do and am happy to see that you will return the favor
  • Consider the English department at Harvard University. It has now agreed to remove its survey of English literature for undergraduates, replacing it and much else with four new “affinity groups”
  • there would be no one book, or family of books, that every English major at Harvard would have read by the time he or she graduates. The direction to which Harvard would lead its students in this “clean slate” or “trickle down” experiment is to suspend literary history, thrusting into the hands of undergraduates the job of cobbling together intellectual coherence for themselves
  • Those who once strove to give order to the curriculum will have learned, from Harvard, that terms like core knowledge and foundational experience only trigger acrimony, turf protection, and faculty mutinies. No one has the stomach anymore to refight the Western culture wars. Let the students find their own way to knowledge.
  • In English, the average number of years spent earning a doctoral degree is almost 11. After passing that milestone, only half of new Ph.D.’s find teaching jobs, the number of new positions having declined over the last year by more than 20 percent; many of those jobs are part-time or come with no possibility of tenure. News like that, moving through student networks, can be matched against, at least until recently, the reputed earning power of recent graduates of business schools, law schools, and medical schools. The comparison is akin to what young people growing up in Rust Belt cities are forced to see: the work isn’t here anymore; our technology is obsolete.
  • unlike other members of the university community, they might well have been plying their trade without proper credentials: “Whereas economists or physicists, geologists or climatologists, physicians or lawyers must master a body of knowledge before they can even think of being licensed to practice,” she said, “we literary scholars, it is tacitly assumed, have no definable expertise.”
  • English departments need not refight the Western culture wars. But they need to fight their own book wars. They must agree on which texts to teach and argue out the choices and the principles of making them if they are to claim the respect due a department of study.
  • They can teach their students to write well, to use rhetoric. They should place their courses in composition and rhetoric at the forefront of their activities. They should announce that the teaching of composition is a skill their instructors have mastered and that students majoring in English will be certified, upon graduation, as possessing rigorously tested competence in prose expression.
  • The study of literature will then take on the profile now held, with moderate dignity, by the study of the classics, Greek and Latin.
  • But we can, we must, do better. At stake are the books themselves and what they can mean to the young. Yes, it is just a literary tradition. That’s all. But without such traditions, civil societies have no compass to guide them.

  • Could the emotional connotations of words in literature be a kind of lagging economic indicator? According to scientists who analyzed a century’s worth of writing, they might: After using big-data techniques to document the frequency of sad and happy words in millions of books, the researchers concluded that the emotional mood of literature reflects the mood of the economy over the previous 10 years.
  • They then matched that against a well-known indicator called the “economic misery index” — the sum of inflation rates and unemployment rates — and found that literary misery in a given year correlated with the average of the previous decade’s economic misery index numbers.

  • Still, the practice of applying data-sorting algorithms to art can only go so far. For one thing, the lists of emotion words, created by other researchers and used for years, include some surprising choices: words like “smug” and “wallow” were among 224 words on the “joy” list; potentially neutral adjectives like “dark” and “low” were among 115 words on the “sadness” list.

  • The response from  fellow economists, so far mainly from the liberal side of the spectrum, has verged on the rapturous. Mr. Krugman,  a columnist for The New York Times, predicted in The New York Review of Books that Mr. Piketty’s book would “change both the way we think about society and the way we do economics.”
  • Mr. Piketty’s dedication to data has long made him a star among economists, who credit his work on income inequality (with Emmanuel Saez and others) for diving deep into seemingly dull tax archives to bring an unprecedented historical perspective to the subject.
  • Six years after the financial crisis, “people are looking for a bible of sorts,” said Julia Ott, an assistant professor of the history of capitalism at the New School, who appeared on a panel with Mr. Piketty at New York University on Thursday. “He’s speaking to a real feeling out there that things haven’t been fixed, that we need to take stock, that we need big ideas, big proposals, big global solutions.”

  • At the book’s center is Mr. Piketty’s contention — contrary to the influential theory developed by Simon Kuznets in the 1950s and ’60s — that mature capitalist economies do not inevitably evolve toward greater economic equality. Instead, Mr. Piketty contends, the data reveals a deeper historical tendency for the rate of return on capital to outstrip the overall rate of economic growth, leading to greater and greater concentrations of wealth at the very top.
  • Mr. Piketty rejected any economic determinism. “It all depends on what the political system decides,” he said.
  • Mr. Piketty, who writes in the book that the collapse of Communism in 1989 left him “vaccinated for life” against the “lazy rhetoric of anticapitalism,” is no Marxian revolutionary. “I believe in private property,” he said in the interview. “But capitalism and markets should be the slave of democracy and not the opposite.”

The realisation that you have absolute freedom to decide the course of your life – jump or don’t jump – is as dizzying as vertigo, explains Kierkegaard, who suggests that we face the same anxiety in all of life’s choices. Every action we take is a choice, decided upon by us and no one else.
