Insight From Trouble in Recognizing Objects
The New York Times: Object agnosia is a rare disorder in which an individual cannot visually recognize objects. In the case of a patient known as SM, he mistook a harmonica for a cash register. Researchers from Carnegie Mellon and Princeton University studied SM’s brain and discovered that it was affected not only in the portion of the right hemisphere that had been damaged in a car accident, but also in his structurally intact left hemisphere. They performed functional M.R.I. brain scans on the patient and report their findings in the journal Neuron. The part of the brain where an image is processed, known as the lower visual cortex, was similar in SM and in normal test subjects.

The Vitamin Paradox
Last night I had a chocolate milkshake for dinner. I don’t eat like this all the time, but often enough. I eat lots of salads, but I also eat cheeseburgers. And if I’m tired I eat pretzels, or skip eating entirely. In short, I’m far from a nutritional purist. But I take a multi-vitamin every day, and have for as long as I can remember. I figure it’s the least I can do for my personal health, plus it’s easy and fairly cheap. I guess I’m hedging my bets. And I’m not alone. Sales of nutritional supplements have grown dramatically over the past decade or so, and now total more than $20 billion a year. More than half of Americans take some kind of vitamin pill.

The Joy of a Sun Bath, a Snuggle, a Bite of Pâté
The New York Times: Two ring-tailed lemurs, perhaps a pair, perhaps just two guys out to catch a few rays, sit side by side tilted back as if in beach chairs, their white bellies exposed, knees apart, feet splayed to catch every last drop of the Madagascar sun. All they need are cigars to complete the picture. There’s a perfectly good evolutionary explanation for this posture. Scientists use the term “behavioral thermoregulation” to describe how an animal maintains a core body temperature. But as the animal behaviorist Jonathan Balcombe points out in his exuberant look at animal pleasure, “The Exultant Ark,” they are also clearly enjoying themselves. A scientist through and through, Dr.

The Willful Blindness of Rupert Murdoch
The Huffington Post: After every institutional debacle, the arguments are the same: it was just a few bad apples. Nobody at the top is to blame. A few rogue, or over-zealous employees just went off piste. Then the full scale of the debacle emerges and another face-saving fiction emerges: no one could possibly have seen this coming. Both arguments were wrong in Abu Ghraib, at Enron, WorldCom, BP, Countrywide and Lehman Brothers and both are wrong today at News International. The phone hacking scandal, and the enormous price paid for it by News Corporation, isn't the unfortunate byproduct of a few naughty freelancers. Nor was it an unpredictable, unforeseeable event.

Soccer: le secret des tirs de barrage
Metro Montreal: Au lendemain de la défaite des États-Unis contre le Japon en tirs de barrage dimanche en finale de la Coupe du monde de soccer féminin, il est de bon ton de se pencher sur une étude qui affirme que les gardiens de but ont tendance à plonger à droite plus souvent quand leur équipe tire de l’arrière durant une fusillade. Pendant les tirs au but, les Américaines n’ont fait mouche qu’une fois en quatre tentatives, tandis que les Japonaises ont marqué trois fois sur quatre frappes. Or, à chacun des quatre tirs nippons, la gardienne américaine s’est lancée vers la droite… Intéressant. Lire plus: Metro Montreal

Work Engagement, Job Satisfaction, and Productivity—They’re a Virtuous Cycle
Engaged workers—those who approach their work with energy, dedication, and focus—are more open to new information, more productive, and more willing to go the extra mile. Moreover, engaged workers take the initiative to change their work environments in order to stay engaged. What do we know about the inner workings of work engagement, and how can employers enhance it to improve job performance? In a new article to be published in the August issue of Current Directions in Psychological Science , a journal of the Association for Psychological Science, Arnold B. Bakker creates a model of work engagement based on the best current research.
