El cansancio y los encuentros agresivos afectan la memoria de los policías
CNN Mexico: Los oficiales de policía que tienen al menos 60 segundos de actividad física intensa durante un encuentro combativo pueden sufrir pérdida de memoria, según un estudio publicado en la revista Psychological Science. Los investigadores descubrieron que los agentes que perseguían a un sospechoso o que participaban en un altercado físico con una persona olvidaban detalles del incidente e incluso eran incapaces de identificar al sospechoso en una fila. Lorraine Hope, de la Universidad de Portsmouth en Gran Bretaña y autora principal del estudio, dijo que los hallazgos son una "advertencia" para los oficiales, jefes de policía e incluso para el sistema judicial.

Putting and Perception: How does Tiger “see” Augusta?
I’m a huge Tiger Woods fan, and I’ve never wavered, even as he has suffered through one of the worst slumps in the history of golf. Tiger ruled the sport for more than a decade, before a sex scandal and injuries derailed him in 2009. He’s never regained his form or confidence, but I haven’t given up on his redemption. There’s a glimmer of hope. In late March, Tiger won his first PGA tour event in 30 months, offering a glimpse of his former dominance. But the real proof that he’s the same old Tiger will be winning a major tournament, and the major of all majors is taking place this week, as golf’s elite meet in Augusta, Georgia for the Masters.

Income Inequality and Distrust Foster Academic Dishonesty
College professors and students are in an arms race over cheating. Students find new sources for pre-written term papers; professors find new ways to check the texts they get for plagiarized material. But why are all these young people cheating? A new study published in Psychological Science, a journal of the Association for Psychological Science, suggests one reason: income inequality, which decreases the general trust people have toward each other. Lukas Neville, a doctoral student at Queen’s University in Ontario, was inspired to do the study by his own teaching experience. “I ran into the question of academic dishonesty firsthand,” he says.

Brain Stores Objects by Color, Too
How do we know what a lemon is, or a baseball? “Theories that explain how our brains store knowledge say that similar knowledge is stored in similar places. So things that are related - in how they look, how they smell, and so on - should overlap in the brain,” says Eiling Yee of the Basque Center on Cognition, Brain, & Language. In other words, the same part of your brain might store the information that both lemons and canaries are yellow. This sort of overlap has been shown for certain properties of objects, like their shape and function, or even for how you manipulate them with your hands.

Real Good For Free: The Paradox of Leisure Time
I’m pretty busy. Like most people I know, I try to balance a lot of different things—a full-time job, household chores, cooking and meals, regular exercise, time with family and friends. Throw in an occasional bike ride, a movie or museum, maybe even reading a book—oh, and sleep—and there aren’t many free minutes left in a typical week. Yet I volunteer my time, too. I do this because it’s a good cause, but also because it makes me feel good. And somewhat surprisingly, I’ve never had the sense that this is one more obligation chipping away at my already compressed day. Indeed, it sometimes seems the other way around, as if working for free eases the time pressure of modern life.

Canadian group studies impact of social networks on mental health
Montreal Gazette: A couple of months ago, Marisa Murray stepped out to grab a bite to eat with a friend. The restaurant they chose was busy, and the table they sat at was shoehorned between two large families. They didn't mind, but as Murray settled in, she found herself paying more attention to the people at the tables beside her than the person at her own. What caught the clinical psychology student's eye was that the families were socializing, but not with each other: Everyone, from the children to the grandparents, was nose deep in an electronic device. "It was so strange. There was no conversation. Within the family, everyone had a cellphone.
