Meet the woman who can't feel fear - The Washington Post - 1 views

  • "Tell me what fear is," Tranel began. "Well, that's what I'm trying to -- to be honest, I truly have no clue," SM said, her voice raspy. That's actually a symptom of the condition that stole fear from her. Urbach-Wieth disease
  • Even though she's a talented artist, she always has trouble drawing (or reading) a fearful facial expression. "I wonder what it's like, you know, to actually be afraid of something," she told Tranel.
  • That's actually just one of two times that SM has been held at knife point. She's also been held at gunpoint twice. And after the above incident, she didn't feel like she should call the police. The threat had passed. She didn't have any lasting trauma, because the event had failed to faze her. SM isn't stupid. She understands what can and can't kill her. But she lacks the quick, subconscious, visceral response that the rest of us feel when we're exposed to danger.

Don't Ban 'Bossy' : The New Yorker - 2 views

  • There are precedents for such reclaiming—pejorative words like “queer” and even “slut,” for instance, which their targets have taken over and brandished with pride. But maybe a more apt comparison would be the word “nerd.” “Nerd” used to be a put-down—and it used to cover boys more often than girls. Like “bossy,” it wasn’t really that harsh, but it wasn’t nice, either. It actually had a gender dimension, too, because it called out brainy boys who were not athletic or aggressive. It was a dis of boys who lived in their heads and wore pocket protectors and ate their lunch indoors, playing chess. Just as “bossy” might be said to undermine female leadership, “nerd” might be said to have undermined male intellectualism. But now “nerd,” and its close cousin “geek,” are words that lots of people are happy to identify with, humble-bragging about their obsessive expertise. Brainiac techies can get rich these days, and that has helped spiff up the image of nerdery. John Green, an author of young-adult novels, and his brother Hank have developed a thriving online and off-line community of “nerdfighters,” girls as well as boys, who like to say that they fight for good with their brains and hearts, calculators and trombones. They have heartthrobs like the actor Benedict Cumberbatch. They find each other on Tumblr.

Teens do better in science when they know Einstein and Curie also struggled - Quartz - 0 views

  • Students who learned that great scientists struggled, both personally and intellectually, outperformed those who learned only of the scientists’ great achievements, new research shows.
  • “In our culture we always say you don’t want to intimidate kids, you don’t want to tell them how hard the work is,” she noted. But the experiment showed the opposite strategy works better: Showing how great scientists had to muddle through lots of tough stuff made the subject matter real and allowed students to connect with them as people.
  • Some people learn better when the content has meaning to them. For those students, science comes to life more through personal stories than through the actual scientific content.

  • And kids who learn that intellect is a malleable thing, something to be built rather than inherited, take more academic risks and perform better. The study adds to the growing body of research in favor of teaching this “growth mindset” or the belief that the brain, like other muscles in the body, can be strengthened and improved through struggle and hard work.

Imitation is what makes us human and creative - Kat McGowan - Aeon - 3 views

  • Throughout human history, innovation – including the technological progress we cherish – has been fuelled and sustained by imitation. Copying is the mighty force that has allowed the human race to move from stone knives to remote-guided drones, from digging sticks to crops that manufacture their own pesticides.
    • Philip Drobis
       
      Imitation is the source for technological advance --by copying others inventions we can add our own potentially benefit to them, thus providing a small contribution to its advancement
  • advances happen largely through tinkering, when somebody recreates a good thing with a minor upgrade that makes it slightly better.
  • When Isaac Newton talked about standing on the shoulders of giants, he should have said that we are dwarves, standing atop a vast heap of dwarves.

  • Lots of copying means that many minds get their chance at the problem; imitation ‘makes the contents of brains available to everyone’, writes the developmental psychologist Michael Tomasello in the Cultural Origins of Human Cognition (1999). Tomasello, who is co-director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, calls the combination of imitation and innovation the ‘cultural ratchet’. It is like a mechanical ratchet that permits motion in only one direction – such as winding a watch, or walking through a turnstile. Good ideas push the ratchet forward one notch. Faithful imitation keeps the ratchet from slipping backward, protecting ideas from being forgotten or lost and keeping knowledge alive for the next round of improvement.

      Multiple minds are essentially key as the cumulative opportunities of each individual given a chance at the issue can lead to one finding something prosperous 
  • In the 1930s, a pair of psychologists raised an infant chimp alongside their own baby in an attempt to understand both species better. The chimp raised in this family (and others in other such experiments later in the century) never behaved much like a human. The human child, on the other hand, soon began knuckle-walking, biting, grunting and hooting – just like his new sibling.

      We copy to survive. Only we humans actually have the 'push' or are gullible enough to not realize as the Chimp example above proposes. -Ties to a biological and/or physiological connection in terms of behavior

The Mystery of S., the Man with an Impossible Memory | The New Yorker - 0 views

  • The researcher who met with S. that day was twenty-seven-year-old Alexander Luria, whose fame as a founder of neuropsychology still lay before him. Luria began reeling off lists of random numbers and words and asking S. to repeat them, which he did, in ever-lengthening series. Even more remarkably, when Luria retested S. more than fifteen years later, he found those numbers and words still preserved in S.’s memory. “I simply had to admit that the capacity of his memory had no distinct limits,” Luria writes in his famous case study of S., “The Mind of a Mnemonist,” published in 1968 in both Russian and English.

Do Our Senses Reveal the World or Obscure It? | Big Think - 0 views

  •  
    a 5-min video with neuroscientist Beau Lotto about how we cannot accurately know reality through our senses, but we perceive what we've learned to perceive and what is useful for us to function in the world; he uses examples including colour; some technical explanations that physics students might like
