Embattled Childhood: The Real ‘T’ in ‘PTSD’
The Huffington Post: In 2009 a regiment of Danish soldiers, the Guard Hussars, was deployed for a six-month tour in Afghanistan's arid Helmand Province, a Taliban stronghold. They were stationed along with British soldiers -- 270 in all -- at a forward operating base called Armadillo. Although none of the Guard Hussars was killed during the tour of duty, they nevertheless experienced many horrors of battle. A commander was seriously injured by a roadside bomb, and a night patrol ended in a firefight that killed and dismembered several Taliban combatants.

Wide-Faced Men: Good Guys or Bad?
TIME: Think of the stereotypical tough guy: broad-faced, square-jawed, uber-macho. Research even bears out this convention, linking wider, more masculine faces with characteristics like dishonesty, lack of cooperation and perceived lack of warmth. But a new study challenges the notion that wide-faced men are always the bad guys, finding that in certain situations, they’re actually the most self-sacrificing of the bunch. For the study, researchers from the Perception Lab at the University of St. Andrews in Scotland gave 54 male students money to play a game in groups.

Knowledge of Fractions and Long Division Predicts Long-Term Math Success
From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy. Yet, over the past 30 years, mathematics achievement of U.S. high school students has remained stagnant — and significantly behind many other countries, including China, Japan, Finland, the Netherlands and Canada. A research team led by Carnegie Mellon University’s Robert Siegler has identified a major source of the gap — U. S. students’ inadequate knowledge of fractions and division. Although fractions and division are taught in elementary school, even many college students have poor knowledge of them.

New Research From Current Directions in Psychological Science
Yuko Munakata, Hannah R. Snyder, and Christopher H. Chatham When children are young, they can get stuck in routine ways of thinking and behaving. As children grow, they develop the ability to break out of routines and think more flexibly. In this article, the authors discuss how the development of abstract goal representations supports three key transitions that lead to more flexible behavior. They conclude by discussing the current and future direction of this research. The Brain's Learning and Control Architecture Jason M.

Expectations influences outcomes
United Press International: Suggestion -- a rabbit's foot or a lucky coin -- can influence how people perform on learning and memory tasks, New Zealand and U.S researchers said. Maryanne Garry and Robert Michael of Victoria University of Wellington, New Zealand, and Irving Kirsch of Harvard Medical School in Boston said the powerful and persuasive effect that suggestion has relies on a person's "response expectancies," or the ways in which people anticipate responses in various situations. These expectations set people up for automatic responses that actively influence how people get to the outcome expected, the researchers said.
