A Little Light Relief - New Remedy for an Old Disorder - 0 views

  •  
    Darlene Barry, a freelance writer living in Washington, D.C., used to experience crisis every fall. She would gain weight - as much as 30 pounds over the winter - due to an obsessive craving for food. She also became depressed, irritable, and unable to concentrate on her job. She was constantly tired and slept as much as possible. Miss Barry had a classic case of the winter blues - known today as seasonal affective disorder, or, appropriately, SAD.

Lacan était un imbécile ...Jacques Lacan Was a Fool by George Elerick - 0 views

  •  
    Elerick attempts to interpret what it means to be a Christian in light of Lacan's famous, but asinine, proposition: "I think where I am not, therefore I am where I do not think." What should be immediately present to everyone who reads the proposition is that it is self-contradictory, for it at once denies the possibility of the individual subject to think itself (or re-present itself to itself) by affirming an inexorable fact about the Self, thereby speaking in absolute and universal terms and negating itself. In other words, if Lacan is right about the nature of the individual self/ego, then he is simultaneously wrong. And if he is wrong, which he is, then why bother with the man anymore?

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.

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.
  • ...1 more annotation...
  • 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.

Long-term solitary confinement: a method of torture - 0 views

  •  
    19-01-2011 Medical evidence has shown that long-term solitary confinement is a form of torture. Dr Joost J den Otter, Medical Director at the International Rehabilitation Council for Torture Victims (IRCT), adds that while there is no doubt about the damage caused by long periods of isolation, solitary confinement for a short period may also cause psychological harm. Dr den Otter highlights the fact that many qualitative and quantitative scientific studies have documented how solitary confinement in prison has damaging health effects. He asserts that the scientific debate on solitary confinement as a method of torture has been settled for many years, but that it seems there is still confusion among policy makers, prison authorities, and the general public. A recent commentary published by the Journal of the American Academy of Psychiatry and the Law about solitary confinement and mental illness in U.S. Prisons, the authors, Jeffrey L. Metzner and Jamie Fellner, support Dr den Otter's judgment. "Isolation can be psychologically harmful to any prisoner, with the nature and severity of the impact depending on the individual, the duration of confinement, and particular conditions (e.g., access to natural light, books, or radio). Psychological effects can include anxiety, depression, anger, cognitive disturbances, perceptual distortions, obsessive thoughts, paranoia, and psychosis". In August 2010, Physicians for Human Rights published a report (Experiments in Torture) which added to the growing body of evidence that solitary confinement causes psychological harm consistent with torture. In an interview with 'Life's Little Mysteries', Dr Scott Allen, one of the authors of the paper, said that solitary confinement "can lead to anxiety, depression, certainly disorientation, [and] it can even lead to thought disorders including psychotic thoughts." He added "The consequences can be significant." This backs up researcher Peter Scharff Smith, of The Danis

5 Things That Internet Porn Reveals About Our Brains | Sex & the Brain | DISCOVER Magazine - 0 views

  •  
    With its expansive range and unprecedented potential for anonymity, (the Internet gives voice to our deepest urges and most uninhibited thoughts. Inspired by the wealth of unfettered expression available online, neuroscientists Ogi Ogas and Sai Gaddam, who met as Ph.D. candidates at Boston University, began plumbing a few chosen search engines (including Dogpile and AOL) to create the world's largest experiment in sexuality in 2009. Quietly tapping into a billion Web searches, they explored the private activities of more than 100 million men and women around the world. The result is the first large-scale scientific examination of human sexuality in more than half a century, since biologist Alfred Kinsey famously interviewed more than 18,000 middle-class Caucasians about their sexual behavior and published the Kinsey reports in 1948 and 1953. Building on the work of Kinsey, neuroscientists have long made the case that male and female sexuality exist on different planes. But like Kinsey himself, they have been hampered by the dubious reliability of self-reports of sexual behavior and preferences as well as by small sample sizes. That is where the Internet comes in. By accessing raw data from Web searches and employing the help of Alexa-a company that measures Web traffic and publishes a list of the million most popular sites in the world-Ogas and Gaddam shine a light on hidden desire, a quirky realm of lust, fetish, and kink that, like the far side of the moon, has barely been glimpsed. Here is a sampling of their fascinating results, selected from their book, A Billion Wicked Thoughts.
