Sick Body, Vigilant Mind
We know that in keeping the body physically healthy, the mind both conscious and unconscious is a principle actor. Indeed, research has shown that the biological, or physiological, immune system that fights pathogens once they’ve entered the body can be kick-started by the “behavioral immune system,” with which we notice, feel repulsed by, and act to avoid people who might make us sick. Now a study in an upcoming issue of Psychological Science, a journal published by the Association for Psychological Science, offers intriguing new evidence of the connection moving in the other direction: from physiological to psychological immune reactions.

Seeing Isn’t Believing
Pay attention! It’s a universal warning, which implies that keeping close watch helps us perceive the world more accurately. But a new study by Yale University cognitive psychologists Brandon Liverence and Brian Scholl finds that intense focus on objects can have the opposite effect: It distorts perception of where things are in relation to one another. The findings will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science. “Figuring out where objects are in the world seems like one of the most basic and important jobs the brain does,” says Liverence, a graduate student.

A More Progressive Tax System Makes People Happier
The way some people talk, you’d think that a flat tax system—in which everyone pays at the same rate regardless of income—would make citizens feel better than more progressive taxation, where wealthier people are taxed at higher rates. Indeed, the U.S. has been diminishing progressivity of its tax structure for decades. But a new study comparing 54 nations found that flattening the tax risks flattening social wellbeing as well.

People Think The “Typical” Member Of A Group Looks Like Them
What does a typical European face look like according to Europeans? It all depends on which European you ask. Germans think the typical European looks more German; Portuguese people think the typical European looks more Portuguese. That’s the conclusion of a new study which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science. The results shed light on how people think about groups they belong to. Other studies have found that, when people choose typical characteristics for a group they’re in, they’ll pick characteristics more like themselves. But that research was done using words.

Like Mama Bears, Nursing Mothers Defend Babies With A Vengeance
Women who breast-feed are far more likely to demonstrate a "mama bear" effect — aggressively protecting their infants and themselves — than women who bottle-feed their babies or non-mothers, according to a new study in the September issue of Psychological Science, a journal of the Association for Psychological Science. And when breast-feeding women behave aggressively, they register a lower blood pressure than other women, the study found. The results, the researchers say, suggest that breast-feeding can help dampen the body's typical stress response to fear, giving women the extra courage they need to defend themselves.

Patients’ Health Motivates Workers To Wash Their Hands
Can changing a single word on a sign motivate doctors and nurses to wash their hands? Campaigns about hand-washing in hospitals usually try to scare doctors and nurses about personal illness, says Adam Grant, a psychological scientist at The Wharton School, University of Pennsylvania. “Most safety messages are about personal consequences,” Grant says. “They tell you to wash your hands so you don’t get sick.” But his new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, finds that this is the wrong kind of warning. Hand-washing is an eternal problem for hospitals.
