Violent Video Games Linked to Increased Aggression
MSN Health: Violent video games trigger aggression among those who play them, according to a new University of Missouri study. Such players showed more hostility because their brains had become less responsive, or desensitized, to violence -- a response that the researchers linked to increased aggression. "From a psychological perspective, video games are excellent teaching tools because they reward players for engaging in certain types of behavior. Unfortunately, in many popular video games, the behavior is violence," study co-author Bruce Bartholow, an associate professor of psychology at UM College of Arts and Sciences, said in a university news release.

Blanks for the Memories
The Wall Street Journal: A rowdy cousin … an Eeyore T-shirt … a dog-shaped balloon. Why we remember some scenes from early childhood and forget others has long intrigued scientists—as well as parents striving to create happy memories for their kids. One of the biggest mysteries: why most people can't seem to recall anything before age 3 or 4. Now, researchers in Canada have demonstrated that some young children can remember events from even before age 2—but those memories are fragile, with many vanishing by about age 10, according to a study in the journal Child Development this month.

Kids own up to ownership
ScienceNews: Young children are possessed by possessions. Preschoolers argue about what belongs to whom with annoying regularity, a habit that might suggest limited appreciation of what it means to own something. But it’s actually just the opposite, psychologist Ori Friedman of the University of Waterloo in Canada reported on May 28 at the Association for Psychological Science annual meeting. At ages 4 and 5, youngsters value a person’s ownership rights — say, to a crayon — far more strongly than adults do, Friedman and psychology graduate student Karen Neary found.

Researchers say math anxiety starts young
The Washington Post: Math problems make more than a few students — and even teachers — sweat, but new brain research is providing insights into the earliest causes of the anxiety so often associated with mathematics. Mathematics anxiety is more than just disliking math, experts say; someone with math anxiety feels negative emotions when engaging in an activity that requires numerical or math skills. In one forthcoming study, simply suggesting to college students that they would be asked to take a math test triggered a stress response in the hypothalamus of students with high math anxiety.

Want to Solve a Problem? Don’t Just Use Your Brain, but Your Body Too
When we’ve got a problem to solve, we don't just use our brains but the rest of our bodies, too. The connection, as neurologists know, is not uni-directional. Now there’s evidence from cognitive psychology of the same fact. “Being able to use your body in problem solving alters the way you solve the problems,” says University of Wisconsin psychology professor Martha Alibali. “Body movements are one of the resources we bring to cognitive processes.” These conclusions, of a new study by Alibali and colleagues—Robert C.
