The flip side of dietary supplement use
The Washington Post: You know those people who take a million dietary supplements a day and act kind of healthier-than-thou about it? A study to be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, might take some wind out of their sails. In a set of small but clever experiments, researchers from three educational institutions in Taiwan worked to examine whether people who take dietary supplements might treat that behavior as a kind of safety net that entitled them to indulge in foods and activities that aren’t so conducive to good health.

What makes a face appealing to the opposite sex?
USA Today: While it may be true that beauty is in the eye of the beholder, a new computer model helps reveal what's behind peoples' ideas of facial attractiveness. Many studies have concluded that people are drawn to "average" faces and those who fit the conventional notion of attractiveness for a person's gender — "masculinity" in men and "femininity" in women. But psychologists Christopher P. Said of New York University and Alexander Todorov of Princeton University believe attractiveness is more complex than that, so they created a computer model to identify and measure those complexities.

Maybe Just Drunk Enough to Remember
The New York Times: Drunken recollections, especially in rape trials, rarely play well to jurors. In a society that can be quick to turn a skeptical eye toward women who say they were raped — she was scantily dressed, she’s promiscuous, she’s just angry at him — prosecutors of sex crimes say one of their biggest obstacles in the courtroom is alcohol. A rape trial in Manhattan is the latest example. The accuser, who completed her testimony Monday, admitted that she was so drunk on the night in question that she could not remember most of what happened, even the cab ride home.

Want to Ace That Test? Cheer Up!
Studying for a stressful exam can sometimes put us in a bad mood. The last thing we want to do is put on a happy face, but research suggests cheerfulness may help us perform better. A study published in Psychological Science found that being in a positive mood can improve performance on certain cognitive tasks. Volunteers were asked to watch a YouTube video that was found to elicit either a positive, neutral, or negative mood; then they completed learning tasks on a computer. Volunteers who were in a positive mood performed better at tasks that involved selecting rules and testing hypotheses than the volunteers who were put in a neutral or negative mood.

I Know You Can – So I Believe I Can
Do you ever get unusually anxious before taking a test? Do you ever choke and blank-out during a test? If so, research suggests you try thinking about a competent person before you take the test. You’ll perform better than you think you will. A study published in Psychological Science found that people who have test anxiety perform better on a test when they are primed with competency before taking it. Volunteers were measured on their test anxiety, and were placed in either a competency prime group or a control group.
