Pediatric Wheelchair - 0 views

  •  
    The body size differences are paralleled by maturational changes. The smaller body of an infant or neonate is substantially different physiologically from that of an adult. Congenital defects, genetic variance, and developmental issues are of greater concern to pediatricians than they often are to adult physicians.

    A major difference between pediatrics and adult medicine is that children are minors and, in most jurisdictions, cannot make decisions for themselves. The issues of guardianship, privacy, legal responsibility and informed consent must always be considered in every pediatric procedure. In a sense, pediatricians often have to treat the parents and sometimes, the family, rather than just the child. Adolescents are in their own legal class, having rights to their own health care decisions in certain circumstances. In basic terms, pediatricians take care of all of the children's needs from emotional support to medical support.

Poverty Is The Only Reason Young People Don't Get Married - 0 views

  •  
    Young adults today are marrying at lower rates than previous generations, and self-reports suggest that a lack of economic security plays a role in the decline. However, it is unclear which aspects of economic security truly matter with regard to young adult marriage rates: is it a matter of employment, wages, poverty, or housing? Or, do all these factors matter? Moreover, how does the measurement of each concept matter to understanding how an economic prerequisite to marriage may operate among young adults? Finally, are the economic characteristics of men more relevant to marriage rates than those of women, as research about previous generations suggests?

News Blog Articles | Stereotyping Increases With Age | Miller-McCune Online Magazine - 0 views

  • A decade ago, a research team led by William von Hippel of the University of Queensland challenged that assumption. The psychologists proposed that older people may exhibit greater prejudice because they have difficulty inhibiting the stereotypes that regularly get activated in all of our brains. They suggested an aging brain is not as effective in suppressing unwanted information — including stereotypes.
  • This finding supports our suggestion that older adults are more likely to make stereotypic inferences during comprehension, and that this stereotyping carries over into their later memory for that information
  • older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that information is incorrect.

  • In real life, of course, no one is pointing out biased statements as they emerge from the mouths or friends, family members or talk-show hosts. So for older adults, the best advice might be to avoid acquaintances who speak in stereotypes. This research suggests prejudice can be contagious, and we become more susceptible as our brains age.
  •  
    we are all prejudiced, and judge through making use of stereotypes- but older people find it difficult to suppress them, whereas we do it quite efficiently. Good news is, if these stereotypes are challenged, they see the light and shed their prejudices.

Don't Shelter Your Children: Coping With Stress As A Child Develops Resilience And Emot... - 5 views

  • We already know that "suffering builds character", but a new study suggests that it may do a lot more than that.
  • Successfully coping with stress at an early age may significantly increase your chances of being a more resilient adult, as well as strengthen your ability to regulate emotions.
  • Parents may feel that by preventing their child from encountering any and all potential hardship they are helping to preserve their emotional well-being, but going through a little stress and encouraging them to cope with it effectively will benefit them far more when it comes to being a more resilient, independent, and emotionally stable adult.
  • ...6 more annotations...
  • Stressful experiences that are challenging but not overwhelming appear to promote the development of subsequent resilience in children.
  • Youths that were exposed to stress actually had less anxiety, lower levels of stress, and had more confidence in exploring novel situations
  • after coping with stress successfully, your brain says, "Hey, that wasn't too bad. I can handle this."
  • The key point in the article is that mild stress exposure resulted in positive changes in the brain, not torture or a series of near-death experiences.
  • The take-home point is this: not all stress is bad.
  • You can't buffer your child from every non-happy moment in his life, so at least take comfort in the fact that while he is suffering in the short term, he is enhancing his well-being in the long term.

Science News / Don't Worry, Get Attention Training - 0 views

  • Attention training helps subjects practice how not to focus on threatening words or on photos of threatening faces
  • anxiety disorder to achieve remission. The disorder, estimated to affect 6.8 million U.S. adults, involves constant, exaggerated worries about impending disasters regarding health, money or other issues.
  • A similar form of attention guidance, directed by psychologist Norman Schmidt of Florida State University in Tallahassee, provided marked relief for many patients diagnosed with social anxiety disorder. About 15 million U.S. adults struggle with this condition, which is characterized by a debilitating dread of everyday social situations and a fear of being watched and judged by others.

How we solve some mental problems with our hands | KurzweilAI - 0 views

  •  
    When we've got a problem to solve, we don't just use our brains but the rest of our bodies as well, researchers at the University of Wisconsin have determined. The researchers recruited 86 American undergraduates, half of whom were prevented from moving their hands using Velcro gloves that attached to a board. The others were prevented from moving their feet, using Velcro straps attached to another board - but had their hands free. From the other side of an opaque screen, an experimenter asked questions about gears in relation to each other. For example: "If five gears are arranged in a line, and you move the first gear clockwise, what will the final gear do?" The participants solved the problems aloud and were videotaped. The videotapes were analyzed for the number of hand gestures the participants used (hand rotations or "ticking" movements, indicating counting); verbal explanations indicating the subject was visualizing those physical movements; or the use of more abstract mathematical rules, without reference to perceptual-motor processes. The researchers then repeated the experiment and analysis with 111 British adults. The researchers found that the people who were allowed to gesture usually did so, and they also commonly used perceptual-motor strategies in solving the puzzles. The people whose hands were restrained (as well as those who chose not to gesture even when allowed), used abstract, mathematical strategies much more often. Their work will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science.

Understanding the Anxious Mind - NYTimes.com - 0 views

  • But some people, no matter how robust their stock portfolios or how healthy their children, are always mentally preparing for doom. They are just born worriers, their brains forever anticipating the dropping of some dreaded other shoe. For the past 20 years, Kagan and his colleagues have been following hundreds of such people, beginning in infancy, to see what happens to those who start out primed to fret. Now that these infants are young adults, the studies are yielding new information about the anxious brain.
  • Four significant long-term longitudinal studies are now under way: two at Harvard that Kagan initiated, two more at the University of Maryland under the direction of Nathan Fox, a former graduate student of Kagan’s. With slight variations, they all have reached similar conclusions: that babies differ according to inborn temperament; that 15 to 20 percent of them will react strongly to novel people or situations; and that strongly reactive babies are more likely to grow up to be anxious.
  • In the brain, these thoughts can often be traced to overreactivity in the amygdala, a small site in the middle of the brain that, among its many other functions, responds to novelty and threat. When the amygdala works as it should, it orchestrates a physiological response to changes in the environment. That response includes heightened memory for emotional experiences and the familiar chest pounding of fight or flight. But in people born with a particular brain circuitry, the kind seen in Kagan’s high-reactive study subjects, the amygdala is hyperreactive, prickly as a haywire motion-detector light that turns on when nothing’s moving but the rain. Other physiological changes exist in children with this temperament, many of them also related to hyperreactivity in the amygdala. They have a tendency to more activity in the right hemisphere, the half of the brain associated with negative mood and anxiety; greater increases in heart rate and pupil dilation in response to stress; and on occasion higher levels of the stress hormones cortisol and norepinephrine.

  • The physiological measurements led them to believe something biological was at work. Their hypothesis: the inhibited children were “born with a lower threshold” for arousal of various brain regions, in particular the amygdala, the hypothalamus and the hypothalamic-pituitary-adrenal axis, the circuit responsible for the stress hormone cortisol.
  • At age 4, children who had been high-reactive were four times as likely to be behaviorally inhibited as those who had been low-reactive. By age 7, almost half of the jittery babies had developed symptoms of anxiety — fear of thunder or dogs or darkness, extreme shyness in the classroom or playground — compared with just 10 percent of the more easygoing ones. About one in five of the high-reactive babies were consistently inhibited and fearful at every visit up to the age of 7.
  • By adolescence, the rate of anxiety in Kagan’s study subjects declined overall, including in the high-risk group. At 15, about two-thirds of those who had been high-reactors in infancy behaved pretty much like everybody else.
  • PEOPLE WITH A nervous temperament don’t usually get off so easily, Kagan and his colleagues have found. There exists a kind of sub-rosa anxiety, a secret stash of worries that continue to plague a subset of high-reactive people no matter how well they function outwardly. They cannot quite outrun their own natures: consciously or unconsciously, they remain the same uneasy people they were when they were little.
  • Teenagers who were in the group at low risk for anxiety showed no increase in activity in the amygdala when they looked at the face, even if they had been told to focus on their own fear. But those in the high-risk group showed increased activity in the amygdala when they were thinking about their own feelings (though not when they were thinking about the nose). Once again, this pattern was seen in anxiety-prone youngsters quite apart from whether they had problems with anxiety in their daily lives. In the high-risk kids, even those who were apparently calm in most settings, their amygdalas lighted up more than the others’ did.
  • Behaviorally inhibited children were much more likely to have older siblings: two-thirds of them did, compared with just one-third of the uninhibited children. Could having older siblings, he and his co-authors wondered, mean being teased and pushed, which becomes a source of chronic stress, which in turn amplifies a biological predisposition to inhibition?
  • high-reactive babies who went to day care when they were young were significantly less fearful at age 4 than were the high-reactives who stayed home with their mothers.
  • The predictive power of an anxiety-prone temperament, such as it is, essentially works in just one direction: not by predicting what these children will become but by predicting what they will not. In the longitudinal studies of anxiety, all you can say with confidence is that the high-reactive infants will not grow up to be exuberant, outgoing, bubbly or bold. Still, while a Sylvia Plath almost certainly won’t grow up to be a Bill Clinton, she can either grow up to be anxious and suicidal, or simply a poet. Temperament is important, but life intervenes.

    This is a good article that looks at how anxiety happens- it is more or less something you are born with, but you learn to live with, if you are intelligent about it. Liked it. Good writing.

*A Brain Scientist's Take on Writing*: What Mirror Images and Foreign Scripts Tell Us A... - 0 views

  • For most adults in literate countries, reading is so well practiced that it’s reflexive. If the words are there, it's impossible not to read.
  • If you raise a child on a desert island, he'll learn to eat, walk, and sleep, but odds are he won't spontaneously pick up a stick and start writing. For most of human history, written language didn't even exist. Reading as a cultural invention has only been around for a few thousand years, a snap of a finger in evolutionary terms.
  • we’re very good at seeing, and the trick is just to retune that machinery to the demands of reading.
  • ...11 more annotations...
  • But even on a basic visual level, we have to somewhat reprogram our visual systems.
  • Mirror invariance, the idea that something flipped sideways is still the same object, is a core property of our visual systems, and for good reason.
  • What's the mirror image of b? Now it's a completely different letter: d.
  • Mirror reversal is overwhelmingly common in beginning writers, from the occasional flipped letter to whole words written as a mirror image. Kids do this spontaneously. They never actually see flipped letters in the world around them. It's as if their brains are too powerful for the task.
  • With practice however, we do retrain our brains to read
  • Does the brain of a reader look different from that of a nonreader?
  • Since blood flow is tied to brain activity, fMRI allows us to see the patches of brain involved in different tasks.
    • Sarah Eeee
       
      Bit of an oversimplification, no?
  • They found that most participants did indeed have a brain region that responded more to words than objects.
  • This is rather remarkable, that the brain would develop a specialized area for an artificial category of images.
  • need more proof that this region developed as a result of learning to read.
  • If reading experience does alter the brain, you would expect English readers and English/Hebrew readers to have different brain responses to Hebrew. And this is indeed what Baker found. The bilingual readers had high activation for both Hebrew and English in their word region, while monolingual English readers only had high activation for English.

BPS Research Digest: This picture will make it more likely that you'll seek help - 0 views

    visual cues subconsciously affect mood & behavior. See the picture that will make it more likely that you'll seek help http://ow.ly/5DhBb
  •  
    Prompts in the environment make their way beneath your conscious radar and into your mind, affecting your mood and behaviour. Past research has shown that a briefcase, as opposed to a rucksack, on a table, leads people to behave more competitively. A wall poster featuring a pair of staring eyes increases people's use of an honesty box. And a 2009 study found that pictures of companionable dolls increased the likelihood that toddlers would help a stranger pick up sticks they'd dropped. Now Mark Rubin at the University of Newcastle has added to this literature with an adult study showing that pictures of companionship don't just increase the giving of help, they also increase the intention to seek help.
