Two Heads Are Not Always Better Than One
From the corporate boardroom to the kitchen table, important decisions are often made in collaboration. But are two—or three or five—heads better than one? Not always, according to new research from the University of Pennsylvania’s Wharton School. “People who make judgments by working with someone else are more confident in those judgments. As a result they take less input from other people”—and this myopia wipes out any advantage a pair may have over an individual, says psychologist Julia A. Minson, who conducted the study with Jennifer S. Mueller.

Lefties vs. Righties: How we decide differently
Yahoo: We like to think that we make decisions based on our ideas of right and wrong -- and we do, to an extent. But according to recent research, our choices may also be influenced by something as simple as whether we're right or left handed. That's because right-handed people are more drawn to things on the right side of a screen or page, while left-handed people look to the left. Cognitive scientist Daniel Casasanto of The New School for Social Research says it's part of the "body-specificity hypothesis" -- the idea that our physical bodies affect the decisions we make and the way we communicate with one another.

Sitting inside a big box made of cardboard and plastic pipe, college students were assigned to complete a word task designed to measure creativity. Sitting outside an identical box, a second group of students completed the same task. Read the whole story: NPR

The Rehash Hangover
Oprah.com: Symptom: You can't stop talking about what happened with your stubborn husband/boss/mother. Causes: This habit is called "co-ruminating," says Amanda Rose, an associate professor of psychological science at the University of Missouri. She has found that while we expect that getting everything off our chest will make us feel better, that often isn't true. "We've seen that there's a snowball effect where talking about your problems causes you to dwell on them, and dwelling makes you feel depressed, which makes you complain even more," she says.

Preschool Kids Best Prepared for Kindergarten: Study
U.S. News & World Report: All children can benefit from going to preschool, especially those who come from minority or poor families or from homes where parents don't provide much mental stimulation, a new study says.

The Forgetting Pill Erases Painful Memories Forever
Wired Magazine: Jeffrey Mitchell, a volunteer firefighter in the suburbs of Baltimore, came across the accident by chance: A car had smashed into a pickup truck loaded with metal pipes. Mitchell tried to help, but he saw at once that he was too late. The car had rear-ended the truck at high speed, sending a pipe through the windshield and into the chest of the passenger—a young bride returning home from her wedding. There was blood everywhere, staining her white dress crimson. Mitchell couldn’t get the dead woman out of his mind; the tableau was stuck before his eyes. He tried to tough it out, but after months of suffering, he couldn’t take it anymore.
