Marginal Revolution: Scientific hypotheses from 1956 - 0 views

  •  
    This article was from the Guardian: Intelligence tests recently carried out among more than a thousand children in Wolverhampton schools appear to show a striking and quite unexpected increase in the mental capacity of children born since 1945. A psychiatrist concerned in the tests has suggested that the most probable hypothesis to account for this change is the effect on the brain of the increase in "background radio-activity". For the pointer I thank Michelle Dawson.

Mind - Research Upends Traditional Thinking on Study Habits - NYTimes.com - 4 views

  • Take the notion that children have specific learning styles, that some are “visual learners” and others are auditory; some are “left-brain” students, others “right-brain.” In a recent review of the relevant research, published in the journal Psychological Science in the Public Interest, a team of psychologists found almost zero support for such ideas.
  • We have yet to identify the common threads between teachers who create a constructive learning atmosphere
  • many study skills courses insist that students find a specific place, a study room or a quiet corner of the library, to take their work. The research finds just the opposite.

    Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I'd spend hours strolling through long stretches of prose. That's rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I'm always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle."

Shocker: Empathy Dropped 40% in College Students Since 2000 | Psychology Today - 1 views

  • While it so obviously measures empathy that you could easily game it to make yourself look kinder and nicer, the fact that today's college students don't even feel compelled to do that suggests that the study is measuring something real. If young people don't even care about seeming uncaring, something is seriously wrong.
  • Though social media is an improvement on passive TV viewing and can sometimes aid real friendships, it is still less rich than face to face interaction. This is especially important for the youngest children whose brains are absorbing social information that will shape the way they connect for the rest of their lives.
  • Perhaps an even larger factor is the merging of the left's "do your own thing" individualism with the right's glorification of brutal competition and unfettered markets. You wind up with a society that teaches kids that "you're on your own" and that helping others is for suckers.

  • if you know nothing about someone's real situation, it's easy to caricature it as being defined by bad choices and laziness, rather than understand the constraints and limits the economy itself imposes. Seeing yourself doing so well and others doing poorly tends to bolster ideas that "you deserve your wealth," simply because guilt otherwise becomes uncomfortable, even unbearable.
