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.
  • ...8 more annotations...
  • 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.

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.

The Blog : Drugs and the Meaning of Life : Sam Harris - 1 views

  •  
    Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts. Every waking moment-and even in our dreams-we struggle to direct the flow of sensation, emotion, and cognition toward states of consciousness that we value.Drugs are another means toward this end. Some are illegal; some are stigmatized; some are dangerous-though, perversely, these sets only partially intersect. There are drugs of extraordinary power and utility, like psilocybin (the active compound in "magic mushrooms") and lysergic acid diethylamide (LSD), which pose no apparent risk of addiction and are physically well-tolerated, and yet one can still be sent to prison for their use-while drugs like tobacco and alcohol, which have ruined countless lives, are enjoyed ad libitum in almost every society on earth. There are other points on this continuum-3,4-methylenedioxymethamphetamine (MDMA or "Ecstasy") has remarkable therapeutic potential, but it is also susceptible to abuse, and it appears to be neurotoxic.[1]One of the great responsibilities we have as a society is to educate ourselves, along with the next generation, about which substances are worth ingesting, and for what purpose, and which are not. The problem, however, is that we refer to all biologically active compounds by a single term-"drugs"-and this makes it nearly impossible to have an intelligent discussion about the psychological, medical, ethical, and legal issues surrounding their use. The poverty of our language has been only slightly eased by the introduction of terms like "psychedelics" to differentiate certain visionary compounds, which can produce extraordinary states of ecstasy and insight, from "narcotics" and other classic agents of stupefaction and abuse.

FSU.com :: New York City to use FSU professor's scale to identify gifted students - 0 views

  • The Gifted Rating Scales is a teacher rating scale designed to help identify gifted students and is based on a multidimensional model of giftedness. By design, GRS minimizes observational bias and increases measurement accuracy. There are two forms: the GRS-P (for preschool/kindergarten level) and the GRS-S (designed specifically for students in grades 1-8). The GRS measures students' aptitude in six areas: Intellectual Ability: measures the child's verbal and nonverbal mental skills and intellectual competence. Items on this scale rate the child's memory, reasoning ability, problem solving and mental speed. Academic Ability: measures the child's skill in dealing with factual and/or school-related material. Items rate readiness and advanced development/proficiency in reading, math and other aspects of the early childhood curriculum. Creativity: measures the child's ability to think, act and/or produce unique, novel or innovative thoughts or products. Items rate the child's imaginative play, original thinking and inventive approach to situations or problems. Artistic Talent: measures the child's potential for, or evidence of ability in, drama, music, dance, drawing, painting, sculpture, singing, playing a musical instrument and/or acting. Leadership: measures the child's ability to motivate people toward a common goal. Motivation: refers to the child's drive, tendency to enjoy challenging tasks, and ability to work well without encouragement or reinforcement. The motivation scale is not viewed as a type of giftedness, but rather as the energy that impels a young child to achieve.

Mind - How Nonsense Sharpens the Intellect - NYTimes.com - 0 views

  • The brain evolved to predict, and it does so by identifying patterns. When those patterns break down — as when a hiker stumbles across an easy chair sitting deep in the woods, as if dropped from the sky — the brain gropes for something, anything that makes sense. It may retreat to a familiar ritual, like checking equipment. But it may also turn its attention outward, the researchers argue, and notice, say, a pattern in animal tracks that was previously hidden. The urge to find a coherent pattern makes it more likely that the brain will find one.
  • “The fact that the group who read the absurd story identified more letter strings suggests that they were more motivated to look for patterns than the others,” Dr. Heine said. “And the fact that they were more accurate means, we think, that they’re forming new patterns they wouldn’t be able to form otherwise.”
  • Brain-imaging studies of people evaluating anomalies, or working out unsettling dilemmas, show that activity in an area called the anterior cingulate cortex spikes significantly. The more activation is recorded, the greater the motivation or ability to seek and correct errors in the real world, a recent study suggests
  • ...2 more annotations...
  • For another, studies have found that people in the grip of the uncanny tend to see patterns where none exist — becoming more prone to conspiracy theories, for example. The urge for order satisfies itself, it seems, regardless of the quality of the evidence.
  • Still, the new research supports what many experimental artists, habitual travelers and other novel seekers have always insisted: at least some of the time, disorientation begets creative thinking.
  •  
    A sense of the absurd sharpens your intellect: you find more meaning after you've been through something that makes no sense at all.
