Hard-Wired for Giving
The Wall Street Journal: The Darwinian principle of "survival of the fittest" echoes what many people believe about life: To get ahead, you need to look out for No. 1. A cursory read of evolutionary doctrine suggests that the selfish individuals able to outcompete others for the best mates and the most resources are most likely to pass their genes on to the next generation. Then there is classical economic theory, which holds that given the choice, we will often opt for a personal benefit over a personal loss, even if that loss involves a benefit to someone else.

Poverty strains cognitive abilities, opening door for bad decision-making, new study finds
The Washington Post: Poverty consumes so much mental energy that people struggling to make ends meet often have little brainpower left for anything else, leaving them more susceptible to bad decisions that can perpetuate their situation, according to a study published Thursday in the journal Science. “Past research has often blamed [poverty] on the personal failings of the poor. They don’t work hard enough; they’re not focused enough,” said University of British Columbia professor Jiaying Zhao, who co-authored the study as a Princeton University graduate student. “What we’re arguing is it’s not about the individual. It’s about the situation.” Read the whole story: The Washington Post

How You Tune Out Your Spouse—and Why
TIME: Spouses have always had a funny way of both hearing and not hearing each other. On the one hand, the person you married is the person with whom you conduct the most intimate business of your life, and on a day to day, moment to moment basis, you must always be in communication. On the other hand, that constant stream of talk can become something of a hum—the conversational equivalent of the buzz of a fan or the thrum of an air conditioner that you hear so much you stop hearing at all. At least that’s the faintly scientific excuse I, and I suspect a lot of other husbands and wives, inwardly make when we’re caught not listening.

How Money Worries Can Scramble Your Thinking
NPR: There's no question that dealing with mortgages, car payments and other bills takes up time and energy. But having a tight budget may also zap our ability to think clearly, scientists Thursday in the journal Science. In a series of clever experiments involving farmers in India and shoppers in New Jersey, scientists found that people are worse at solving puzzles — similar to those on the IQ test — when they're first reminded of money problems. "Financial constraints capture a lot of your attention," says Eldar Shafir, a psychologist at Princeton University, who helped lead the study. "Then there's less bandwidth left to solve problems.

Girls’ fear of math debunked, study suggests
CBC News: While girls tend to say they feel anxious about doing math, they are not actually much more anxious than their male counterparts during math classes or exams, according to new research by German and Canadian researchers. Researchers from Humboldt University Berlin, the University of Munich and McGill University in Montreal say they've identified a key failing in previous studies that said girls are far more apprehensive about doing math than their male peers. Previous studies asked students about generalized perceptions of mathematics anxiety rather than asking them directly about their anxiety while doing math.

Food Is Tastier When Part of a Ritual
Scientific American: Food can taste better when you’re really hungry. Now a study reveals another condition that can enhance the flavor of a meal: when it’s part of a ritual. Scientists asked volunteers to eat some chocolate. They told one group to relax for a few minutes, then eat the chocolate in any way they wanted. But another group was given these instructions: “Without unwrapping the chocolate bar, break it in half. Unwrap half of the bar and eat it. Then, unwrap the other half and eat it.” Read the whole story: Scientific American
