Crew Schedules, Sleep Deprivation, and Aviation Performance
Night-time departures, early morning arrivals, and adjusting to several time zones in a matter of days can rattle circadian rhythms, compromise attention and challenge vigilance. And yet, these are the very conditions many pilots face

Do anti-tobacco ads work? Ask a ‘neural focus group’
While watching TV this weekend, I happened on a gruesomely powerful anti-smoking advertisement. It featured former smokers who were missing body parts—a woman with missing fingers and a handsome young man with two prosthetic devices where his lower legs used to be. Both talked matter-of-factly about their permanent disabilities, which were direct consequences of their long-time cigarette habits. This ad is part of a new, $54 million campaign by the U.S. Centers for Disease Control, the most ambitious and starkest anti-tobacco campaign ever undertaken by the government. Other ads in the campaign show ex-smokers who have had their larynx removed, or a jaw or a lung.

That Impulsive, Moody Preschooler May Grow Up to Be a Problem Gambler
Give me the child at 3 and I will give you the adult compulsive gambler. That is the striking finding of a new study in Psychological Science, a journal published by the Association for Psychological Science. Based on tests of over 900 individuals beginning in toddlerhood, the study found that “people who were rated at age three as being more restless, inattentive, oppositional, and moody than other three-year old children were twice as likely to grow up to have problems with gambling as adults three decades later,” says psychologist Wendy S. Slutske of University of Missouri, who conducted the study with Terrie E.

Does being needy in a relationship make you feel colder?
Yahoo! Canada: The next time you reach for that warm sweater, or pine for some hot comfort food, you might wonder whether you suffer from attachment anxiety. In a report called "Warm Thoughts: Attachment Anxiety and Sensitivity to Temperature Cues," published in Psychological Science, Ohio University psychology professor Matthew Vess, shows how people with attachment issues are especially sensitive to temperature cues. In the first of two studies outlined in the report, a group of 56 people tested to measure their levels of anxiety in relationships.

Tromper son cerveau pour être meilleur au golf
Le Figaro: Des chercheurs américains en sciences cognitives ont découvert un étrange effet de perception qui peut être utile au golf. Il suffit d'imaginer que le trou sur le green est plus large qu'il ne l'est vraiment pour améliorer de 10 % les chances de faire entrer la balle dans le trou. Les golfeurs le savent bien: c'est au petit jeu que se fait la différence! L'étude qui vient d'être publiée dans Psychological Science risque donc d'intéresser plus d'un acharné du green. Elle montre en effet que l'on peut améliorer son putting par le simple jeu de l'imagination. «Les joueurs améliorent leurs putts quand ils ont l'illusion que le trou est plus large» explique Jessica K.

The Innate Irresistibility of Film
Scientific American: When I was seven years old, my mom took me to see Curly Sue. Though I don’t remember much of the movie, two scenes made quite the impression: the first, when James Belushi asks Alisan Porter to hit him on the head with a baseball bat, and the second, when Bill, Sue, and Grey sit in the 3-D movie theater. At first glance, that second one doesn’t seem to pack quite the same punch–insert pun grimace here–as a little girl swinging a huge bat at a man’s forehead. But I found it irresistible. A wide shot of the entire movie theater, and all of the faces—in 3-D glasses, of course—moving and reacting in perfect unison. Heads swerve left. Heads swerve right. Gasps. Ducks.
