How the hot hand delusion messes with the game
The Boston Globe: HERE’S SOME ADVICE for NBA coaches: If one of your players is on a hot streak, tell him to cool off. An analysis of consecutive shots in the 2010-2011 NBA season finds that players who had just scored during regular play (not a free throw), especially from longer range, were more likely to take the next shot for their team. However, that follow-up shot was riskier, as it was more likely to be taken from longer range, and was therefore more likely to miss. Read the whole story: The Boston Globe

The new (and nastier) ageism
America is a rapidly graying society. This demographic trend has been underway for a while—and anticipated for a long while—yet some of its implications are just now coming into focus. Most notably, the aging of America will almost certainly trigger a retirement crisis, with elderly boomers competing for limited financial and medical resources—and working longer just to stay afloat. The elderly have never been honored in American society. They have more often been stereotyped, stigmatized and pitied as outdated and weak, both physically and mentally.

Does Our Innate Ability to Estimate Numbers Benefit From Education?
Children are born with an innate number sense -- the ability to discriminate quickly between different amounts or numbers of objects, even without counting. And research has shown that children who have a more acute number sense -- or Approximate Number System (ANS) -- are also better at mathematics. In a new article published in Psychological Science, researcher Manuela Piazza of the Cognitive Neuroimaging Unit at INSERM in France and colleagues sought to understand whether improvements in ANS ability come naturally with age or whether they are the result of formal education. The researchers tested 38 subjects from an indigenous Mundurucú population in Brazil.

Au bureau, assumons nos erreurs (How to accept our mistakes)
Le Monde: Lisa Legault, chercheuse en psychologie à l'université Clarkson (Etats-Unis), vient d'en faire la démonstration, avec son équipe. Son article "Préserver son intégrité quand nos performances sont menacées : l'affirmation de soi accroît la réponse neurophysiologique aux erreurs" était publié dans le numéro de février de la revue Psychological Science. Les chercheurs américains ont mené une première expérience qui consistait à déstabiliser la moitié d'un groupe de participants. Puis ils leur ont fait faire un test. Quand ils se trompaient, "Faux", criait le système, pour effrayer les cobayes encore davantage.

If Your Shrink Is A Bot, How Do You Respond?
NPR: Her hair is brown and tied back into a professional-looking ponytail. She wears a blue shirt, tan sweater and delicate gold chain. It's the first time she has met the man sitting across from her, and she looks out at him, her eyes curious. ... Now, obviously this work raises all kinds of issues, and even on a practical level, real obstacles remain. Jeff Cohn, a psychologist at the University of Pittsburgh, studies the relationship between physical movements and emotion and says signals from the face, voice and body are incredibly complicated to interpret. "Individuals vary a lot in how expressive they are," Cohn explains.
