A pair of studies by The Children’s Hospital of Philadelphia (CHOP) and State Farm® identify factors that may lead teens to drive with multiple peer passengers and, then, how those passengers may affect their driver’s behavior just before a serious crash. The studies were published today in the Journal of Adolescent Health.

Experts have long known that peer passengers increase teen driver crash risk. What hasn’t been well understood was how they increase crash risk. “These studies help us understand the factors that may predispose teens to drive with multiple friends and how those passengers may contribute to crashes by distracting the driver and promoting risky driving behaviors, such as speeding, tailgating, or weaving,” said study author Allison Curry, PhD, director of epidemiology at the Center for Injury Research and Prevention. “Knowing this, we can develop programs that work in tandem with current Graduated Driver Licensing laws that limit the number of passengers for teens during their first year of driving.” [continue reading…]

A neuro-imaging study shows that personal values that people refuse to disavow, even when offered cash to do so, are processed differently in the brain than those values that are willingly sold.

“Our experiment found that the realm of the sacred – whether it’s a strong religious belief, a national identity or a code of ethics – is a distinct cognitive process,” says Gregory Berns, director of the Center for Neuropolicy at Emory University and lead author of the study. The results were published in Philosophical Transactions of the Royal Society.

Sacred values prompt greater activation of an area of the brain associated with rules-based, right-or-wrong thought processes, the study showed, as opposed to the regions linked to processing of costs-versus-benefits.

Berns headed a team that included economists and information scientists from Emory University, a psychologist from the New School for Social Research and anthropologists from the Institute Jean Nicod in Paris, France. The research was funded by the U.S. Office of Naval Research, the Air Force Office of Scientific Research and the National Science Foundation.

“We’ve come up with a method to start answering scientific questions about how people make decisions involving sacred values, and that has major implications if you want to better understand what influences human behavior across countries and cultures,” Berns says. “We are seeing how fundamental cultural values are represented in the brain.” Link to continue reading

After the huge 2010 oil spill in the Gulf of Mexico, the chairman of BP referred to the victims of the spill as the “small people.” He explained it as awkward word choice by a non-native speaker of English, but the authors of a new paper published in Psychological Science, a journal of the Association for Psychological Science, wondered if there was something real behind it. In their study, they found that people who feel powerful tend to overestimate their own height—they feel physically larger than they actually are.

“Maybe there’s a physical experience that goes along with being powerful,” says Jack A. Goncalo of Cornell University, who cowrote the paper with Michelle M. Duguid of Washington University. “For people who are less powerful, maybe other people and objects loom larger, and for the powerful everything else just seems smaller.” Plenty of research has shown that taller people are more likely to acquire power; taller people make more money, on average, and are more likely to be promoted. But our research is the first to show the reverse may also be true power also makes people feel taller. [continue reading…]
