La douleur renforce la cohésion dans le groupe
Slate France: Partager une expérience douloureuse peut créer un sentiment de solidarité au sein d'un groupe, rapporte une étude publiée dans Psychological Science. En effet, la douleur pourrait avoir des conséquences sociales positives car elle agit «comme une sorte de "ciment social" qui favorise la cohésion et la solidarité au sein d'un groupe», rapporte l'article. «Les résultats mettent en lumière les raisons pour lesquelles les camaraderies peuvent se développer entre les soldats ou les autres personnes qui partagent des expériences difficiles et douloureuses», explique Brock Bastian, chercheur en psychologie à l'université de Queensland en Australie.

Loneliness narrows the uncanny valley
CNET: Talking to inanimate objects when you're feeling lonely may not be so strange after all. According to new research conducted by a team at Darmouth College in the UK and Harvard University in the US, we're more likely to perceive life in inanimate faces when we're feeling socially disconnected. In short, if you're low on human contact, you might start feeling a little less creeped out by the uncanny valley -- because those faces look more alive to you. This is because, when people are starved of social contact, they start attributing human characteristics to objects: a face on a volleyball, for instance. Or a doll. Or... a robot.

Why Hands-Free Phones Are A Driving Danger
By now, we should all know that talking on a cell phone while driving is a bad idea. So far, 14 states have banned driving with a handheld phone, but researchers caution that hands-free phones may be just as dangerous and distracting. In 2011 the National Transportation Safety Board called for an end to all cellphone use in the car saying, "there is no difference between hand-helds and hands-free." New research from a team of psychological scientists from Carleton University in Ottawa, Canada further confirms that even hands-free phone conversations can have a negative impact on driver performance.

‘The New Statistics’ Video Tutorial Is Now Online
Leading scholars in psychology and other disciplines are advocating the use of the “new statistics” — effect sizes, confidence intervals, and meta-analysis — to help scientists enhance the way they conduct, analyze, and report their research. APS’s flagship journal, Psychological Science, has been inviting authors to use the new statistics as part of a comprehensive effort to enhance behavioral research. In a new online tutorial workshop, APS Fellow Geoff Cumming, an emeritus professor at La Trobe University in Australia and a leader in the new statistics movement, explains why these changes are necessary and suggests ways psychological scientists can implement them.

Some Things You Can Do In Your Sleep, Literally
NPR: For those who find themselves sleeping through work — you may one day find yourself working through sleep. People who are fast asleep can correctly respond to simple verbal instructions, according to a study by researchers in France. They think this may help explain why you might wake if someone calls your name or why your alarm clock is more likely to rouse you than any other noise.

When Taking a Break Could Be a Matter of Life and Death
Knowledge@Wharton: The so-called “secondary tasks” that many professionals are expected to attend to at work can become big problems when ignored over time — think about a trucker constantly forgetting to obey the speed limit, even if only by a few miles per hour. But new Wharton research shows for the first time that those little things can begin to slip through the cracks due to fatigue that develops even within a single work day. In some cases, that drop-off can cost tens of thousands of lives and cost billions of dollars a year. Wharton operations and information management professor Katherine L. Milkman and Wharton Ph.D.
