Combat Stress Among Veterans Is Found to Persist Since Vietnam
The New York Times: Most veterans who had persistent post-traumatic stress a decade or more after serving in the Vietnam War have shown surprisingly little improvement since then, and a large percentage have died, a new study finds, updating landmark research that began a generation ago. Members of minorities who enlisted before finishing high school were especially likely to develop such war-related trauma, as were those veterans who had killed multiple times in combat, the study found.

Visual Exposure Predicts Infants’ Ability to Follow Another’s Gaze
Following another person’s gaze can reveal a wealth of information critical to social interactions and also to safety. Gaze following typically emerges in infancy, and new research looking at preterm infants suggests that it’s visual experience, not maturational age, that underlies this critical ability. The research is published in Psychological Science, a journal of the Association for Psychological Science.

Trauma of War, Illusion of Growth
Back in 2009, the U.S. Army undertook a dramatic transformation of its own culture. The country had been at war for almost a decade, with many soldiers repeatedly deployed to the battlefields of Iraq and Afghanistan. The intense and cumulative stress of protracted conflict was taking a devastating toll—reflected in high rates of post-traumatic stress disorder, family problems, and an all-time high in suicides. In response, the Army leadership embraced psychological science, especially some ideas of positive psychology that had previously been antithetical to the military’s warrior ethos.

Smoking Up Behind the Wheel Linked to Risky Driving While Sober
Driving under the influence of drugs or alcohol has been tied in previous studies to other dangerous driving behaviors, like speeding and dangerous overtaking, but research investigating the relationship between cannabis and risk of car accidents has produced contradictory results. Psychological scientists Isabelle Richer and Jacques Bergeron of the University of Montreal looked at whether those who drive while under the influence of cannabis are more likely to engage in risky and aggressive driving behaviors in general. An all-male group of 75 participants was given a questionnaire asking about their driving habits, cannabis use, and history of car accidents.

One question reveals: Are you a narcissist?
USA TODAY: If you are a narcissist, you probably think this story is about you, and you are correct (as you so often are – right?). That kind of thinking makes it quite easy for researchers to identify the most self-involved among us: They just ask people if they are narcissists. The real narcissists speak right up, a new study shows. "People who are not narcissists would never say that they are," because of the negative traits – such as vanity and selfishness – associated with the word, says Sara Konrath, a researcher at Indiana University in Indianapolis and, until recently, the University of Michigan-Ann Arbor.

A New Reason to Get More Sleep
Inc.: You probably already know that missing sleep is bad for productivity. Maybe you've also heard that the Centers for Disease Control and Prevention call lack of sleep a public epidemic and links it to industrial disasters and chronic diseases such as obesity and diabetes. But it gets worse. A new study suggests it may damage your memory, too. That's according to researchers at Michigan State University and the University of California, Irvine, who found participants deprived of sleep were more likely to stumble over the details of a simulated burglary they were shown in a series of images.
