Most people who suffer from serious pain have one or more mental images that they associate with the discomfort and what it represents to them. A new study by Clare Philips and Debbie Samsom has shown that these pain-sufferers can be taught to re-imagine this pain imagery in a more positive light, bringing them instant relief and emotional comfort.

After picturing a “re-scripted” pain image, the participants in that group experienced a dramatic drop in their pain levels. In fact, 49 per cent of them said they felt no pain at that time, compared with 11 per cent of them feeling no pain after imagining their index image. “The pain decrements were fast, easily produced and dramatically large,” the researchers said. The re-script group also exhibited improvements in anxiety, sadness, mental defeat and beliefs about their own fragility. The control participants, by contrast, experienced none of these improvements.

Philips and Samsom said that the participants found it easy and pleasurable to re-script their pain images. Of course there is a need now for research to see whether these benefits of re-picturing pain can last into the long term. It would also help to have a different kind of control group - for example, one that merely visualised random positive images, to see if the effects of specifically re-picturing pain are more powerful. Where this study focused on the sensory detail of pain images, future work could also look into the re-writing the images’ cognitive meaning.

The findings add to a broader literature showing that our experience of pain is affected by many psychological factors, such as our beliefs about our ability to cope. This doesn’t mean the pain isn’t real, but it does mean that psychological techniques can be incredibly effective at bringing relief and improvements to people’s quality of life.

From Everything Is Obvious: How Common Sense Fails Us:

So powerful is the appeal of a good story that even when we are trying to evaluate an explanation scientifically—that is, on the basis of how well it accounts for the data—we can’t help judging it in terms of its narrative attributes. In a range of experiments, for example, psychologists have found that simpler explanations are judged more likely to be true than complex explanations, not because simpler explanations actually explain more, but rather just because they are simpler. In one study, for example, when faced with a choice of explanations for a fictitious set of medical symptoms, a majority of respondents chose an explanation involving only one disease over an alternative explanation involving two diseases, even when the combination of the two diseases was statistically twice as likely as the single-disease explanation. Somewhat paradoxically, explanations are also judged to be more likely to be true when they have informative details added, even when the extra details are irrelevant or actually make the explanation less likely.

The Year’s Most Spectacular Microscopic Photos

If you associate camera manufacturer Nikon with those silly ads that feature Ashton Kutcher, you may somewhat relieved to know that they also do some good in the world. As well as making some pretty swanky SLRs, the company manufactures scientific microscopes, and it runs an annual competition for photography at a microscopic scale. This year’s results are in, and the company has published a selection of the winners on its site — and they’re as spectacular as ever. The photos — which we spotted at Ars Technica — are all kinds of amazing, encompassing everything from algae and fossils to a fly’s eye and the curiously perverse beauty of a cancer cell.

“You have competing populations in the brain — one part that wants to tell something and one part that doesn’t,” he tells Fresh Air’s Terry Gross. “And the issue is that we’re always cussing at ourselves or getting angry at ourselves or cajoling ourselves. … What we’re seeing here is that there are different parts of the brain that are battling it out. And the way that that battle tips, determines your behavior.”

Eagleman’s new book, Incognito, examines the unconscious part of our brains — the complex neural networks that are constantly fighting one another and influencing how we act, the things we’re attracted to, and the thoughts that we have.

“All of our lives — our cognition, our thoughts, our beliefs — all of these are underpinned by these massive lightning storms of [electrical] activity [in our brains,] and yet we don’t have any awareness of it,” he says. “What we find is that our brains have colossal things happening in them all the time.”

On today’s Fresh Air, Eagleman explains how learning more about the unconscious portions of our brain can teach us more about time, reality, consciousness, religion and crime.

A decade ago, long before every media executive figured out that downloading was the future, Valve started an online service, Steam. It has since become for games what iTunes is to music — a huge online distributor, in its case one with more than 40 million active users and that, by some estimates, accounts for about 70 percent of the PC games bought and downloaded from the Web. Through Steam, Valve effectively collects a toll on other companies’ online game sales, in addition to making money from selling its own products.

Now Valve executives think they may be onto the next big thing in games: wearable computing. The goggles I’m wearing — reminiscent of the ones Google recently unveiled to much hoopla — could unlock new game-playing opportunities. This technology could let players lose themselves inside a virtual reality and, eventually, blend games with their views of the physical world.

Valve fosters unorthodox thinking through a corporate culture unusual even by the quirky standards of technology companies. While many start-ups pay lip service to flat organizational structures, Valve emphasizes that its workplace is truly “boss-less.”

“We don’t have any management, and nobody ‘reports to’ anybody else,” reads Valve’s handbook for new employees, which generated buzz this year when it leaked onto the Web.

To spur creativity, Google management created the concept of “20 percent time,” the portion of employees’ schedules that they could commit to entirely self-directed projects. At Valve, it’s more like 100 percent time. New employees aren’t even told where to work in the company. Instead, they are expected to decide on their own where they can contribute most. Many desks at Valve are on wheels. After figuring out what they want to do, workers simply push their desks over to the group they want to join.

Valve has an eclectic work force. The company became interested in hiring one artist only after learning that his pastime was spray-painting graffiti art in Britain. It recently hired Leslie Redd, a school administrator, to lead an effort to use “Portal” to teach physics and other subjects in schools by offering a more engaging way to present ideas like escape velocity. Ms. Redd said that more than 2,000 teachers worldwide had registered to use the game in classes.

This year, Mr. Newell hired Yanis Varoufakis, a Greek economist, after being impressed with Mr. Varoufakis’s personal blog, which he fills with commentary on the European financial crisis. Mr. Varoufakis, who had never heard of Valve and is not a gamer, is studying the workings of the virtual economies of Valve games, in which players can barter and sell items like hats and armor. He said he was drawn to the job partly by Valve’s “completely anti-authoritarian” culture that, to his surprise, seemed to be working.

Valve’s most striking recruiting campaign is a recent move to establish a hardware group to develop technologies that can enhance the playing of games. The company posted a job listing for an industrial designer, hinting that it planned to get into the computer business itself. “We’re frustrated by the lack of innovation in the computer hardware space, though, so we’re jumping in,” the listing read. “Even basic input, the keyboard and mouse, haven’t really changed in any meaningful way over the years.”

Valve can do without many formalities of a traditional company because it’s privately held and controlled by Mr. Newell. He and Mike Harrington, who is no longer with the company, founded Valve in 1996 with the wealth they accumulated in Microsoft’s early days. The company has never raised money from outside investors, so it is under no external pressure to sell itself or go public.

Among the many challenges teachers face, often the most difficult is how to engage students who seem unreachable, who resist learning activities, or who disrupt them for others. This is also one of the challenges that skilled teachers have some control over. In my nine years of teaching high school, I’ve found that one of the best approaches to engaging challenging students is to develop their intrinsic motivation.

How can teachers do this? It’s helpful to consider this question in three parts: What skilled teachers think, what they say, and what they do.

What Skilled Teachers Can Think

  1. Remember that authoritative beats authoritarian. […]

  2. Believe that everyone can grow. […]

  3. Understand that power isn’t a finite pie. […]

What Skilled Teachers Can Say

  1. Give positive messages.

  2. Apologize. [… for any mistakes]

What Skilled Teachers Can Do

  1. Be flexible. […]

  2. Set the right climate. […]

  3. Teach life lessons. […]

The Practice of Mindfulness

A former Buddhist nun who is now the director of Mindfulness Education at UCLA Mindful Awareness Center reveals her own discovery and practice of mindfulness, discusses some scientific studies, and talks about mental and physical health benefits.

She defines mindfulness as paying attention to our present experience. It’s interrupting our automatic pilot, which gives our lives new vitality. Children are very mindful but as we grow up we lose that sense of presence. With practice we can learn to reconnect with our true nature and return to the present.

She then guides the audience (and viewers) through a mindfulness exercise.

10 of the Most Breathtaking Panoramic Photos We’ve Ever Seen

Photographs rarely live up to the fullness of actually being there. But more and more digital technology provides new ways to counteract the flatness of photos, elevating panoramic and high-resolution photography to new realms both in terms of technique and in the way images are presented. 360-degree rotation, massive composites, and interactive controls allow us to explore photography in some very enticing ways. For the voyeuristically inclined, the advent of huge multi-giga-pixel images means zooming and panning indefinitely across an endless sea of visual detail. We’ve gathered ten such breathtaking panoramas for you to feast your eyes upon. Click through the links and take your time exploring some truly spacious visual masterpieces.
