I Had Asperger Syndrome. Briefly. - NYTimes.com - 0 views

  •  
    "FOR a brief, heady period in the history of autism spectrum diagnosis, in the late '90s, I had Asperger syndrome. There's an educational video from that time, called "Understanding Asperger's," in which I appear. I am the affected 20-year-old in the wannabe-hipster vintage polo shirt talking about how keen his understanding of literature is and how misunderstood he was in fifth grade. The film was a research project directed by my mother, a psychology professor and Asperger specialist, and another expert in her department. It presents me as a young man living a full, meaningful life, despite his mental abnormality. "Understanding Asperger's" was no act of fraud. Both my mother and her colleague believed I met the diagnostic criteria laid out in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The manual, still the authoritative text for American therapists, hospitals and insurers, listed the symptoms exhibited by people with Asperger disorder, and, when I was 17, I was judged to fit the bill. I exhibited a "qualified impairment in social interaction," specifically "failure to develop peer relationships appropriate to developmental level" (I had few friends) and a "lack of spontaneous seeking to share enjoyment, interests, or achievements with other people" (I spent a lot of time by myself in my room reading novels and listening to music, and when I did hang out with other kids I often tried to speak like an E. M. Forster narrator, annoying them). I exhibited an "encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus" (I memorized poems and spent a lot of time playing the guitar and writing terrible poems and novels). The general idea with a psychological diagnosis is that it applies when the tendencies involved inhibit a person's ability to experience a happy, normal life. And in my c

Many Medals but No Consensus for Phelps as 'Greatest Olympian' - NYTimes.com - 0 views

  •  
    "The races will continue in the Aquatics Center for Michael Phelps this week but, in one sense, the race is already over. Phelps has now won more medals than any Olympian: summer or winter, spring or fall. But if you think that must make Phelps, by acclamation, the greatest Olympian in history, it is not that simple. "

How Did Economists Get It So Wrong? - NYTimes.com - 1 views

  •  
    "I. MISTAKING BEAUTY FOR TRUTH It's hard to believe now, but not long ago economists were congratulating themselves over the success of their field. Those successes - or so they believed - were both theoretical and practical, leading to a golden era for the profession. On the theoretical side, they thought that they had resolved their internal disputes. Thus, in a 2008 paper titled "The State of Macro" (that is, macroeconomics, the study of big-picture issues like recessions), Olivier Blanchard of M.I.T., now the chief economist at the International Monetary Fund, declared that "the state of macro is good." The battles of yesteryear, he said, were over, and there had been a "broad convergence of vision." And in the real world, economists believed they had things under control: the "central problem of depression-prevention has been solved," declared Robert Lucas of the University of Chicago in his 2003 presidential address to the American Economic Association. In 2004, Ben Bernanke, a former Princeton professor who is now the chairman of the Federal Reserve Board, celebrated the Great Moderation in economic performance over the previous two decades, which he attributed in part to improved economic policy making. Last year, everything came apart. Few economists saw our current crisis coming, but this predictive failure was the least of the field's problems. More important was the profession's blindness to the very possibility of catastrophic failures in a market economy. During the golden years, financial economists came to believe that markets were inherently stable - indeed, that stocks and other assets were always priced just right. There was nothing in the prevailing models suggesting the possibility of the kind of collapse that happened last year. Meanwhile, macroeconomists were divided in their views. But the main division was between those who insisted that free-market economies never go astray and those who believed that economie

New York Study of Pedestrian Victims Leads to Unexpected Conclusions - NYTimes.com - 0 views

    • anonymous
       
      A human/social science study of the streets of NYC.
  • Taxis, it turns out, are not a careering menace: cabs, along with buses and trucks, accounted for far fewer pedestrian accidents in Manhattan than did private automobiles. Jaywalkers were involved in fewer collisions than their law-abiding counterparts who waited for the “walk” sign, though they were likelier to be killed or seriously hurt by the collision.

      Can we safely generalize then that NYC men are more dangerous drivers?
  • The study, which the city’s Transportation Department described as the most ambitious of its kind by an American city, examined more than 7,000 crashes that occurred in New York City from 2002 to 2006 and that resulted in the death or serious injury of at least one pedestrian.

  • The findings could also become a tool for the Bloomberg administration to extend its re-engineering of the city’s street grid, which it says saves lives. Those changes, which have angered many drivers, include barring vehicles from major avenues and replacing hundreds of parking spaces with bicycle lanes and walkways. The city says it is already planning a series of street changes based on data in the report.

Wanted - Baby Sitters With Foreign Language Skills - NYTimes.com - 1 views

  • “Once you are trilingual,” she said, “your brain can break down new languages that make it so much easier to learn your fourth, fifth and sixth languages.”
  • In fact, research shows that learning a second language makes it easier to learn additional languages. In recent years, a number of neuroscientists and psychologists have tried to untangle the impact of bilingualism on brain development. “It doesn’t make kids smarter,” said Ellen Bialystok, a professor of psychology at York University in Toronto and the author of “Bilingualism in Development: Language, Literacy and Cognition.” “There are documented cognitive developments,” she said, “but whatever smarter means, it isn’t true.”
  • Ms. Bialystok’s research shows that bilingual children tend to have smaller vocabularies in English than their monolingual counterparts, and that the limited vocabulary tends to be words used at home (spatula and squash) rather than words used at school (astronaut, rectangle). The measurement of vocabulary is always in one language: a bilingual child’s collective vocabulary from both languages will probably be larger.
  • ...3 more annotations...
  • “Bilingualism carries a cost, and the cost is rapid access to words,” Ms. Bialystok said. In other words, children have to work harder to access the right word in the right language, which can slow them down — by milliseconds, but slower nonetheless.
  • At the same time, bilingual children do better at complex tasks like isolating information presented in confusing ways. In one test researchers frequently use, words like “red” and “green” flash across a screen, but the words actually appear in purple and yellow. Bilingual children are faster at identifying what color the word is written in, a fact researchers attribute to a more developed prefrontal cortex (the part of the brain responsible for executive decision-making, like which language to use with certain people). Ms. D’Souza said that both of her sons lagged their peers by almost a year in verbal development. Her pediatrician recommended speech therapy, and one son’s preschool teacher expressed concern that he did not know the alphabet. But when both started speaking, at around 3 years old, they were able to move fluidly among three languages. She said that her older son tested in the 99th percentile for the city’s gifted and talented program. “The flexibility of their thinking helps them in nonlinguistic abilities like science and math,” she said, speaking of her children. “But at the same time the normal things — the alphabet — they have trouble with that.”
  • George P. Davison, head of school at Grace Church School, a competitive downtown school, said that bilingualism tended to suppress verbal and reading comprehension test scores by 20 to 30 percent for children younger than 12. “If anything, it can have a negative effect on admissions,” he said.

Mind - Research Upends Traditional Thinking on Study Habits - NYTimes.com - 1 views

    • anonymous
       
      This is such a comment complaint of teachers, namely that students act, from year to year, as if they don't remember every even being introduced to something that the current year teacher thinks is review. Many grade level teachers begin the year thinking their predecessors in the previous year didn't do a good job preparing their students.
  • These findings extend well beyond math, even to aesthetic intuitive learning.
  • The finding undermines the common assumption that intensive immersion is the best way to really master a particular genre, or type of creative work, said Nate Kornell, a psychologist at Williams College and the lead author of the study. “What seems to be happening in this case is that the brain is picking up deeper patterns when seeing assortments of paintings; it’s picking up what’s similar and what’s different about them,” often subconsciously.

  • But at the very least, the cognitive techniques give parents and students, young and old, something many did not have before: a study plan based on evidence, not schoolyard folk wisdom, or empty theorizing.
  • “With many students, it’s not like they can’t remember the material” when they move to a more advanced class, said Henry L. Roediger III, a psychologist at Washington University in St. Louis. “It’s like they’ve never seen it before.”
  • That’s one reason cognitive scientists see testing itself — or practice tests and quizzes — as a powerful tool of learning, rather than merely assessment. The process of retrieving an idea is not like pulling a book from a shelf; it seems to fundamentally alter the way the information is subsequently stored, making it far more accessible in the future.
  • Dr. Roediger uses the analogy of the Heisenberg uncertainty principle in physics, which holds that the act of measuring a property of a particle (position, for example) reduces the accuracy with which you can know another property (momentum, for example): “Testing not only measures knowledge but changes it,” he says — and, happily, in the direction of more certainty, not less.
  • “Testing has such bad connotation; people think of standardized testing or teaching to the test,” Dr. Roediger said. “Maybe we need to call it something else, but this is one of the most powerful learning tools we have.”
  • Motivation matters. So do impressing friends, making the hockey team and finding the nerve to text the cute student in social studies.
  • The more mental sweat it takes to dig it out, the more securely it will be subsequently anchored.
  • “In lab experiments, you’re able to control for all factors except the one you’re studying,” said Dr. Willingham. “Not true in the classroom, in real life. All of these things are interacting at the same time.”

Do Daughters Cause Divorce? - NYTimes.com - 3 views

  •  
    Parents of girls are 5 percent more likely to divorce than parents of boys. Economists first analyzed the data that way in 2003, when Gordon Dahl at the University of Rochester and Enrico Moretti at U.C.L.A., identified that gap, and noted that it widened as you added boys or girls to a family. Parents of three girls, for instance, are 10 percent more likely to split than are parents of three boys. And, they found, an unmarried couple is more likely to marry if they learn their unborn child will be a boy than a girl.

Why So Many People Can't Make Decisions - WSJ.com - 0 views

    "Seeing the world as black and white, in which choices seem clear, or shades of gray can affect people's path in life, from jobs and relationships to which political candidate they vote for, researchers say. People who often have conflicting feelings about situations-the shades-of-gray thinkers-have more of what psychologists call ambivalence, while those who tend toward unequivocal views have less ambivalence.\n\nHigh ambivalence may be useful in some situations, and low ambivalence in others, researchers say. And although people don't fall neatly into one camp or the other, in general, individuals who tend toward ambivalence do so fairly consistently across different areas of their lives. "
