In Recognizing Faces, the Whole is Not Greater Than the Sum of Its Parts
How do we recognize a face? To date, most research has answered “holistically”: We look at all the features—eyes, nose, mouth—simultaneously and, perceiving the relationships among them, gain an advantage over taking in each feature individually. Now a new study overturns this theory. The researchers—Jason M. Gold and Patrick J. Mundy of the Indiana University and Bosco S. Tjan of the University of Southern California—found that people’s performance in recognizing a whole face is no better than their performance with each individual feature shown alone. “Surprisingly, the whole was not greater than the sum of its parts,” says Gold.

Want to Limit Aggression? Practice Self-Control!
Feeling angry and annoyed with others is a daily part of life, but most people don’t act on these impulses. What keeps us from punching line-cutters or murdering conniving co-workers? Self-control. A new review article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, examines the psychological research and finds that it’s possible to deplete self-control—or to strengthen it by practice. Criminologists and sociologists have long believed that people commit violent crimes when an opportunity arises and they’re low on self-control. “It’s an impulsive kind of thing,” says Thomas F.

The Last Piece Of Chocolate You Eat Is The Best, Says Study
The Huffington Post: A new study published in the journal Psychological Science reveals that the last bite of chocolate you eat will probably taste the best. The study, authored by Ed O'Brien and Phoebe C. Ellsworth of the University of Michigan, piggybacked off previous studies about salient endings. One forerunner had demonstrated that students felt greater affection for their school when reminded about graduation than students not reminded of graduation. The authors explain, in relation to food: Imagine that your favorite restaurant is closing, and you final meal tastes especially delicious.

Decision-Making Under Stress: The Brain Remembers Rewards, Forgets Punishments
TIME: If you’re trying to make an important decision while the baby is crying, the boss is shouting on the phone and the cat has chosen this moment to think outside the box, you might want to take a breather and wait. A new review shows that acute stress affects the way the brain considers the pros and cons, causing it to focus on pleasure and ignore the possible negative consequences of a decision. The research has implications for everything from obesity and addictions to finance, suggesting that stress may modify the way people make choices in predictable ways.

What’s the connection between sexual orientation and education?
Business Insider: Completing college doubled the likelihood that a man identified as gay or bisexual and was associated with a 900% increase in the chance of women identifying as lesbian or bisexual. A college education is associated with more liberal sexual attitudes and behavior, but this effect is greater for women than for men. Even more striking is the association between college education and sexual orientation shown in a recent national survey (Laumann, Gagnon, Michael, & Michaels, 1994).

Hunger Affects What We See
Scientific American: Hunger is the best sauce. And it affects perceptions of anything related to food. Even words. Researchers tested two groups. One group just had lunch. The other hadn't eaten in four hours. The subjects watched computer screens as 80 words flashed by, each for about 1/300th of a second--that's too short to read the words, but just long enough to reach the threshold of conscious awareness. One quarter of the words were food-related. The rest were neutral non-food related words. Read the whole story: Scientific American
