Growing Over Showing in Math Education
In case you missed it, the cameras were rolling at the APS 23rd Annual Convention in Washington, DC. Watch Matthew G. Mandelbaum from Fordham University present his poster session research on “Mastery, Need for Cognition, and Self-Efficacy Promote Long-Term Math Achievement in Adolescent Females.” Mandelbaum’s research shows that “growing” is better than “showing” when it comes to learning math.

Brain Stores Objects by Color, Too
How do we know what a lemon is, or a baseball? “Theories that explain how our brains store knowledge say that similar knowledge is stored in similar places. So things that are related - in how they look, how they smell, and so on - should overlap in the brain,” says Eiling Yee of the Basque Center on Cognition, Brain, & Language. In other words, the same part of your brain might store the information that both lemons and canaries are yellow. This sort of overlap has been shown for certain properties of objects, like their shape and function, or even for how you manipulate them with your hands.

Real Good For Free: The Paradox of Leisure Time
I’m pretty busy. Like most people I know, I try to balance a lot of different things—a full-time job, household chores, cooking and meals, regular exercise, time with family and friends.

Indeed, it sometimes seems the other way around, as if working for free eases the time pressure of modern life.

Montreal Gazette: A couple of months ago, Marisa Murray stepped out to grab a bite to eat with a friend. The restaurant they chose was busy, and the table they sat at was shoehorned between two large families.

What caught the clinical psychology student's eye was that the families were socializing, but not with each other: Everyone, from the children to the grandparents, was nose deep in an electronic device. "It was so strange. There was no conversation. Within the family, everyone had a cellphone.

Learning to Drive With A.D.H.D.
The New York Times: The first time Jillian Serpa tried to learn to drive, the family car wound up straddling a creek next to her home in Ringwood, N.J. Ms. Serpa, then 16, had gotten flustered trying to sort out a rapid string of directions from her father while preparing to back out of their driveway. “There was a lack of communication,” she said. “I stepped on the gas instead of the brake.” On her second attempt to learn, Ms. Serpa recalled, she “totally freaked out” at a busy intersection. It was four years before she tried driving again.

I Think, Therefore I Exercise: Philosophy and Health
Researchers investigate how dualists, who view the body as separate and independent from the mind, tend to see their bodies and, specifically, their fitness and health.
