How to Increase Testosterone Naturally - 0 views

  •  
    It is probаblу good tо explain fіrst whу testosterone is іmpоrtаnt bеfоre I begin to explain ways to naturally boost testosterone levels. Hormones play a very іmрortant role іn оur bodies аnd аrе responsible for mаnу functions аnd activities. Тhe male hormone, testosterone, іs a key ingredient in a weight loss or muscle building program. Іt will help tо reduce fat retention and will аlsо maximize muscle building potential. There аrе numerous benefits tо increased levels оf testosterone, and hеre arе јust a few that аrе relevant fоr fat loss аnd muscle building: * Decrease in body fat percentage * Increase іn muscular size * Increase іn muscular strength * Increase іn muscular endurance There аre mаnу оthеr benefits that are nоt rеlated tо the muscle building equation. Thеse include improvement іn mood аnd a decrease in "bad" cholesterol. It is bесаuse оf thеse benefits that body builders focus a lot of attention оn ways to naturally boost testosterone levels. Іf you learn hоw tо increase testosterone naturally, you'll gеt all the benefits by following thеse easy ways to increase testosterone withоut any оf the negatives associated with steroids and other nasty supplements. 1 - Compound Exercises You're going to the gym anуwaу so changing уour workout tо focus оn mоre compound exercises will not be that difficult. Тrу tо build а weight lifting program that іs developed аrоund a core group of compound exercises lіke squats, deadlifts, bаck rows, bench presses, chin uрs, and оthеrs thаt use sevеrаl large muscle groups rather focusing оn a small muscle. I'm not sауіng to completely ignore isolation exercises for smaller muscles, just tо refocus the workout tо include more compound lifts. 2 - Heavy Weights The harder уоu work іn the gym, the harder yоur body will work tо help thе recovery. Weights саn help tо increase testosterone naturally?

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.

High Caffeine Intake Linked To Hallucination Proneness - 0 views

  • High Caffeine Intake Linked To Hallucination Proneness ScienceDaily (Jan. 14, 2009) — High caffeine consumption could be linked to a greater tendency to hallucinate, a new research study suggests
  • ‘High caffeine users’ – those who consumed more than the equivalent of seven cups of instant coffee a day - were three times more likely to have heard a person’s voice when there was no one there compared with ‘low caffeine users’ who consumed less than the equivalent of one cup of instant coffee a day.  With ninety per cent of North Americans consuming some of form caffeine every day, it is the world's most widely used drug.
  • “Our study shows an association between caffeine intake and hallucination-proneness in students. However, one interpretation may be that those students who were more prone to hallucinations used caffeine to help cope with their experiences. More work is needed to establish whether caffeine consumption, and nutrition in general, has an impact on those kinds of hallucination that cause distress.”

  • Caffeine use can lead to a condition called caffeine intoxication. Symptoms include nervousness, irritability, anxiety, muscle twitching, insomnia, headaches, and heart palpitations. This is not commonly seen when daily caffeine intake is less than 250mg

Musical chills: Why they give us thrills - 0 views

  •  
    ScienceDaily (Jan. 12, 2011) - Scientists have found that the pleasurable experience of listening to music releases dopamine, a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food, drugs and sex. The new study from The Montreal Neurological Institute and Hospital -- The Neuro at McGill University also reveals that even the anticipation of pleasurable music induces dopamine release [as is the case with food, drug, and sex cues]. Published in the journal Nature Neuroscience, the results suggest why music, which has no obvious survival value, is so significant across human society.

Does Your Personality Influence Who You Vote For? - 0 views

    ScienceDaily (Nov. 2, 2008) - Does your personality influence who you vote for? The short answer is yes, according to John Mayer, professor of psychology at the University of New Hampshire. As Americans go to the polls in record numbers to vote for the next U.S. president, some voters will crave social stability and others will crave social change. Liberals and conservatives divide according to these personality preferences.

The grand delusion: What you see is not what you get - life - 16 May 2011 - New Scientist - 0 views

    Your senses are your windows on the world, and you probably think they do a fair job at capturing an accurate depiction of reality. Don't kid yourself. Sensory perception - especially vision - is a figment of your imagination. "What you're experiencing is largely the product of what's inside your head," says psychologist Ron Rensink at the University of British Columbia in Vancouver, Canada. "It's informed by what comes in through your eyes, but it's not directly reflecting it."

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.

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.

Study finds 'magic mushrooms' may improve personality long-term | The Raw Story - 0 views

  •  
    A new study suggests that a single dose of psilocybin -- the active ingredient in "Magic Mushrooms" -- can result in improved personality traits over the long term. Researchers at the Johns Hopkins University School of Medicine found that individuals who received the drug once in a clinical setting reported a greater sense of "openness" that often lasted 14 months or longer, according to study published this week in the Journal of Psychopharmacology. The study defined openness as a personality trait that "encompasses aesthetic appreciation and sensitivity, imagination and fantasy, and broad-minded tolerance of others' viewpoints and values." It is one of five main personality traits that are shared among all cultures worldwide. Of the 51 participants, 30 had personality changes that left them feeling more open. Other personality traits (extroversion, neuroticism, agreeableness and conscientiousness) were not impacted. Only the participants who said they had a "complete mystical experience" while on the drug registered an increased sense of openness. "The mystical experience has certain qualities," lead author Katherine MacLean said. "The primary one is that you feel a certain kind of connectedness and unity with everything and everyone." Because personality traits are generally considered to remain stable throughout a persons lifetime, researchers are excited about therapeutic implications of the study. "[T]his study shows that psilocybin actually changes one domain of personality that is strongly related to traits such as imagination, feeling, abstract ideas and aesthetics, and is considered a core construct underlying creativity in general," study author Roland R. Griffiths told USA Today. "And the changes we see appear to be long-term."

Does sexual equality change porn? - Pornography - Salon.com - 0 views

  •  
    In what may feel like a flashback to the porn wars of the '60s, a new study investigates the link between a country's relative gender equality and the degree of female "empowerment" in the X-rated entertainment it consumes. Researchers at the University of Hawaii focused on three countries in particular: Norway, the United States and Japan, which are respectively ranked 1st, 15th and (yikes) 54th on the United Nations' Gender Empowerment Measure (GEM). To simplify their analysis, their library of smut was limited to explicit photographs of women "from mainstream pornographic magazines and Internet websites, as well as from the portfolios of the most popular porn stars from each nation." Then they set out to evaluate each image on both a disempowerment and an empowerment scale, using respective measures like whether the woman is "bound and dominated" by "leashes, collars, gags, or handcuffs" or "whether she has a natural looking body." Their hypothesis was that societies with greater gender equity will consume pornography that has more representations of "empowered women" and less of "disempowered women." It turned out the former was true, but, contradictory as it may sound, the latter was not. "While Norwegian pornography offers a wider variety of body types -- conforming less to a societal ideal that is disempowering to the average woman -- there are still many images that do not promote a healthy respect for women," the researchers explain. In other words, Norwegian porn showed more signs of female empowerment, but X-rated images in all three countries equally depicted women in demeaning positions and scenarios. This, the researchers surmise, "suggests that empowerment and disempowerment within pornography are potentially different constructs." So, gender equality is accompanied by sexual interest in a broader range of beauty types but not a decrease in porn's infantilization of females, use of dominating fetish gear on women or any of the other characteristics th

WHERE GOOD IDEAS COME FROM by Steven Johnson - YouTube - 0 views

  •  
    One of our most innovative, popular thinkers takes on-in exhilarating style-one of our key questions: Where do good ideas come from? With Where Good Ideas Come From, Steven Johnson pairs the insight of his bestselling Everything Bad Is Good for You and the dazzling erudition of The Ghost Map and The Invention of Air to address an urgent and universal question: What sparks the flash of brilliance? How does groundbreaking innovation happen? Answering in his infectious, culturally omnivorous style, using his fluency in fields from neurobiology to popular culture, Johnson provides the complete, exciting, and encouraging story of how we generate the ideas that push our careers, our lives, our society, and our culture forward. Beginning with Charles Darwin's first encounter with the teeming ecosystem of the coral reef and drawing connections to the intellectual hyperproductivity of modern megacities and to the instant success of YouTube, Johnson shows us that the question we need to ask is, What kind of environment fosters the development of good ideas? His answers are never less than revelatory, convincing, and inspiring as Johnson identifies the seven key principles to the genesis of such ideas, and traces them across time and disciplines. Most exhilarating is Johnson's conclusion that with today's tools and environment, radical innovation is extraordinarily accessible to those who know how to cultivate it. Where Good Ideas Come From is essential reading for anyone who wants to know how to come up with tomorrow's great ideas.

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.

Stoner alert: McDonald's gets you legally high | KurzweilAI - 0 views

  •  
    Fats in foods like potato chips and french fries make them nearly irresistible because they trigger natural marijuana-like chemicals in the body called endocannabinoids, researchers at the University of California, Irvine, have found. The researchers discovered that when rats tasted something fatty, cells in their upper gut started producing endocannabinoids, while sugars and proteins did not have this effect. How fats create, like, a buzz It starts on the tongue, where fats in food generate a signal that travels first to your brain, and then through a nerve bundle called the vagus to your intestines. There, the signal stimulates the production of endocannabinoids, which initiates a surge in cell signaling that prompts you to totally pig out - probably by initiating the release of digestive chemicals linked to hunger and satiety that compel us to eat more. And that leads to obesity, diabetes and cancer, the researchers said. But they suggest it might be possible to curb this process by obstructing endocannabinoid activity: for example, by using drugs that "clog" cannabinoid receptors. The trick: bypassing the brain to avoid creating anxiety and depression (which happens when endocannabinoid signaling is blocked in the brain). I'm guessing McDonald's won't be adding that drug to their fries. Ref.: Daniele Piomelli, et al., An endocannabinoid signal in the gut controls dietary fat intake, PNAS, 2011; in press

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

Education: Learning difficulties | The Economist - 1 views

  •  
    A PARADOX of education is that presenting information in a way that looks easy to learn often has the opposite effect. Numerous studies have demonstrated that when people are forced to think hard about what they are shown they remember it better, so it is worth looking at ways this can be done. And a piece of research about to be published in Cognition, by Daniel Oppenheimer, a psychologist at Princeton University, and his colleagues, suggests a simple one: make the text conveying the information harder to read.
