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.

ScienceDirect - Personality and Individual Differences : Caffeine, stress, and pronenes... - 0 views

  • Caffeine, stress, and proneness to psychosis-like experiences: A preliminary investigation
  • cortisol released in response to stressors is proposed to play a role in the development of psychotic experiences. Individual differences in cortisol response to stressors are therefore likely to play a role in proneness to psychotic experiences.
  • Caffeine intake, stress, hallucination-proneness and persecutory ideation were assessed by self-report questionnaires in a non-clinical sample (N = 219). Caffeine intake was positively related to stress levels and hallucination-proneness, but not persecutory ideation. When stress levels were controlled for, caffeine intake predicted levels of hallucination-proneness but not persecutory ideation.

Hey interwebs! Can I have my brain back? | Ask MetaFilter - 0 views

  • What is it that makes the Internet so compelling to so many? Aside from the obvious fun and entertainment, educational and business opportunities, and show-offism; I think it boils down to a slogan taken from the eighties. No fear! The playing field is level. Size doesn't matter, really. Inhibitions and reservations are out the window. Internet life is people with diseases and addictions, exposing souls and sharing their recoveries. It's about overviews of history warning future generations not to repeat the mistakes of their predecessors. Sure there are a few kooks to throw us off guard, but mostly the Net is just us being ourselves without fear of reprisal. How refreshing. The Internet is people talking and sharing ideas. Our best and brightest, wallflowers and flower children, the girl next door and the Doc who delivered your kids. It's about you and me. We are all using our own cognizant voices, and we're listening too. We're challenging the status quo, and we're offering alternatives. Collaboration on a global scale all tied together by that simplest of cyber friendships, the hyperlink. Communication has never seen anything like it. I first considered all this ten years ago when that sociology study came out. Another ten years later, my life is even more enriched by the Internet. So to answer your question, I don't think it's the Internet that has whacked your brain, I think you might want to be looking elsewhere. If anything, the Internet is keeping you stimulated.

      Some Metafilter users opinions on the Internet and attention span. Netbros takes a very optimistic approach, highlighting the wonderful communication realities & possibilities of the Internet. Still, I can't help but be convinced that my attention span has decreased as social networking has taken up an increasing proportion of my Internet use. When I was 10-11 years old (got my first computer with Internet access), I spent most of my time reading relatively long websites about all sorts of things. (Granted, I had been the kind of kid who read the encyclopedia and lots of non-fiction before we got a computer.) I'm 23 now, and my desktop is usually awash with tabs of news, blog posts, social networking sites, and an array of links I found from these aforementioned places. I hate to blame Twitter, Facebook, email, or any other social networking application. But still - I feel like my attention span has decreased, at a developmental stage when it should likely have increased (going from 10 years old to 23). What are your thoughts?

When Change Is Not Enough: The Seven Steps To Revolution | OurFuture.org - 0 views

  •  
    "Those who make peaceful evolution impossible make violent revolution inevitable."- John F. KennedyThere's one thing for sure: 2008 isn't anything like politics as usual.The corporate media (with their unerring eye for the obvious point) is fixated on the narrative that, for the first time ever, Americans will likely end this year with either a woman or a black man headed for the White House. Bloggers are telling stories from the front lines of primaries and caucuses that look like something from the early 60s - people lining up before dawn to vote in Manoa, Hawaii yesterday; a thousand black college students in Prairie View, Texas marching 10 miles to cast their early votes in the face of a county that tried to disenfranchise them. In recent months, we've also been gobstopped by the sheer passion of the insurgent campaigns of both Barack Obama and Ron Paul, both of whom brought millions of new voters into the conversation - and with them, a sharp critique of the status quo and a new energy that's agitating toward deep structural change.There's something implacable, earnest, and righteously angry in the air. And it raises all kinds of questions for burned-out Boomers and jaded Gen Xers who've been ground down to the stump by the mostly losing battles of the past 30 years. Can it be - at long last - that Americans have, simply, had enough? Are we, finally, stepping out to take back our government - and with it, control of our own future? Is this simply a shifting political season - the kind we get every 20 to 30 years - or is there something deeper going on here? Do we dare to raise our hopes that this time, we're going to finally win a few? Just how ready is this country for big, serious, forward-looking change?Recently, I came across a pocket of sociological research that suggested a tantalizing answer to these questions - and also that America may be far more ready for far more change than anyone really believes is possible at this moment.

On a diet? Try mind over milkshake - health - 05 June 2011 - New Scientist - 0 views

  •  
    IF YOU want to lose weight, convince yourself that everything you eat is highly calorific. It could lower your levels of a hunger hormone, potentially suppressing your appetite. Alia Crum at Yale University and her colleagues gave 46 healthy volunteers the same 380-calorie milkshake but were told it was either a sensible, low-calorie choice or an indulgent, high-calorie one. The team also measured levels of ghrelin - a hormone released by the stomach when we are hungry - before and after participants drank the shake. Ghrelin levels have been shown to spike half an hour before mealtimes and return to normal after eating. Volunteers who thought they had indulged showed significantly greater drops in ghrelin levels than those who thought they had consumed less. The authors suggest that merely thinking that one has eaten something unhealthy can quell hunger pangs and perhaps help curb overeating (Health Psychology, DOI: 10.1037/a0023467). The study shows that food labels can affect consumption in unexpected ways, says David Cummings, an endocrinologist at the University of Washington in Seattle.

Connection to your future self impacts your financial decision-making | KurzweilAI - 0 views

  •  
    How connected consumers feel (or don't feel) to their future selves impacts their spending and savings decisions, researchers at Columbia Business School and The University of Chicago Booth School of Business have determined. The researchers conducted a series of experiments that manipulated the degree to which subjects felt connected to their future selves. When discontinuity with the future self is anticipated, people behave more impatiently - speeding up the consumption of utility (in this case, gift cards) - more than when connectedness to the future self is expected. The researchers asked a group of college seniors - three weeks before graduation - to read a passage that described college graduation either as an event that would prompt a major change in their identities or as an event that would prompt only a relatively trivial change. Compared to students who read the passage describing graduation as a small change, those who read a description of the event as a major change were much more likely to make more impatient choices, choosing to receive a gift certificate worth $120 in the next week rather than wait a year for up to $240. Their work suggests that people can be motivated to hold onto their money, or make more prudent decisions by increasing their sense of connectedness to their future selves, the researchers said.

Bartels & Oleg Urminsky, On Intertemporal Selfishness: How the Perceived Instability of Identity Underlies Impatient Consumption, Journal of Consumer Research, 2011; [DOI: 10.1086/658339]

How your memories can be twisted under social pressure | KurzweilAI - 0 views

  •  
    Listen up, Facebook and Twitter groupies: how easily can social pressure affect your memory? Very easily, researchers at the Weizmann Institute and University College London have proved, and they think they even know what part of the brain is responsible. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. Volunteers watched a documentary film in small groups. Three days later, they returned to the lab individually to take a memory test, answering questions about the film. They were also asked how confident they were in their answers. They were later invited back to the lab to retake the test. This time, the subjects were also given supposed answers of the others in their film-viewing group (along with social-media-style photos) while being scanned in a functional MRI (fMRI) that revealed their brain activity. Is most of what you know false? Planted among these were false answers to questions the volunteers had previously answered correctly and confidently. The participants conformed to the group on these "planted" responses, giving incorrect answers nearly 70% of the time. To determine if their memory of the film had actually undergone a change, the researchers invited the subjects back to the lab later to take the memory test once again, telling them that the answers they had previously been fed were not those of their fellow film watchers, but random computer generations. Some of the responses reverted back to the original, correct ones, but get this: despite finding out the scientists messed with their minds, close to half of their responses remained erroneous, implying that the subjects were relying on false memories implanted in the earlier session. An analysis of the fMRI data showed a strong co-activation and connectivity between two brain areas: the hippocampus and the amygdala. Social reinforcement could act on the amygdala to persuade our brains to replace a strong memory wi
