Real Good for Free: The Paradox of Leisure Time
The Huffington Post: 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. Throw in an occasional bike ride, a movie or museum, maybe even reading a book -- oh, and sleep -- and there aren't many free minutes left in a typical week. Yet I volunteer my time, too. I do this because it's a good cause, but also because it makes me feel good. And somewhat surprisingly, I've never had the sense that this is one more obligation chipping away at my already compressed day.

Perception and Peak Performance
The New York Times: Like many of us during March Madness, Jessica Witt is a college basketball fan. She is also a professor of psychology at Purdue University. Those interests converged recently at a Purdue basketball game, as she watched fans noisily try to distract the opposing players during free throws. The fans hooted, stomped and waved streamers — but it didn’t seem to have any effect on the outcome. Dr. Witt wondered whether other interventions might. As director of the Action-Modulated Perception Lab at Purdue, she’d previously demonstrated that for successful tennis players and field-goal kickers, the ball or goal looks larger than it does to players not enjoying a hot streak.

Brains of Kids With Math Anxiety Function Differently, Says Study
ABC: Kids who get the jitters before a math test may actually have different brain functions than kids without math anxiety, according to a new study. Researchers from the Stanford University School of Medicine recruited about 50 second and third graders and separated them into either a high-math anxiety group or a low-anxiety group based on a standard questionnaire they modified for 7- to 9-year-olds. They scanned the children’s brains while the kids did addition and subtraction problems. They found that children with a high level of math anxiety were slower at solving problems and were less accurate than children with lower math anxiety. Read the whole story: ABC

Good Reads: a new study on God and civilization
The Christian Science Monitor: In The New York Times, Yudhijit Bhattacharjee writes on how learning a second language at an early age makes your brain work better. Psychologists once worried that kids who lived in bilingual households faced obstacles that “hindered a child’s academic and intellectual development.” Turns out they were right, and that very hindrance turns out to be an advantage. In a 2009 study led by Agnes Kovacs of the International School for Advanced Studies in Trieste, Italy, 7-month-old babies exposed to two languages from birth were compared with peers raised with one language.

HPA Activation Leads to Sex Differences in Spatial Attention
In case you missed it, the cameras were rolling at the APS 23rd Annual Convention in Washington, DC. Watch Melissa VanderKaay Tomasulo from St. Michael's College present her poster session research. Stressors in your life, such as navigating traffic or doing a public presentation, activate two main biological stress systems: The HPA axis (hypothalamic-pituitary-adrenal axis) and the SAM axis (sympatho-adrenomedullary axis). Stress research in humans has generally focused on verbal learning and memory. But Melissa M. VanderKaay Tomasulo of Saint Michael's College, along withAnthony E.

Two cheers for multiple-choice tests
The oldest geyser in Yellowstone National Park is: a. Steamboat Geyser b. Old Faithful c. Castle Geyser d. Daisy Geyser We’ve all answered hundreds if not thousands of these multiple-choice questions over the years. We answer them to get our drivers’ licenses, to get into good colleges and grad schools and professional schools. They’re ubiquitous, yet everyone hates them. Educators dismiss them as simplistic, the enemy of complex learning. Students think they’re unfair. And learning experts say they plain don’t work. To be clear, learning experts are questioning the value of these tests as learning tools.
