Tool Manipulation is Represented Similary in the Brains of the Blind and the Sighted
Blind people think about manipulating tools in the same regions of the brain as do people who can see, according to a new study. The researchers say this adds to evidence that the brain has a fairly defined organization, while still being able to adapt to unusual conditions, such as not having any vision. When you look at a glass in front of you on the desk, it sets off a lot of reactions in your brain. Part of your brain categorizes it: "That's a glass!" Another part of the brain thinks about the glass's shape and size, its exact location, and what you would have to do with your hand and arm if you were going to reach out and grab it.

Brain Structure Corresponds to Personality
Personalities come in all kinds. Now psychological scientists have found that the size of different parts of people's brains correspond to their personalities; for example, conscientious people tend to have a bigger lateral prefrontal cortex, a region of the brain involved in planning and controlling behavior. Psychologists have worked out that all personality traits can be divided into five factors, commonly called the Big Five: conscientiousness, extraversion, neuroticism, agreeableness, and openness/intellect. Colin DeYoung at the University of Minnesota and colleagues wanted to know if these personality factors correlated with the size of structures in the brain.

The Psychology of Food Cravings
Swimsuit season is almost upon us. For most of us, the countdown has begun to lazy days lounging by the pool and relaxing on the beach. However, for some of us, the focus is not so much on sunglasses and beach balls, but how to quickly shed those final five or ten pounds in order to look good poolside. It is no secret that dieting can be challenging and food cravings can make it even more difficult. Why do we get intense desires to eat certain foods? Although food cravings are a common experience, researchers have only recently begun studying how food cravings emerge.

A Woman’s Touch: Physical Contact Increases Financial Risk Taking
A woman's touch is all it takes for people to throw caution to the wind. That's the conclusion of a new study published online in Psychological Science, a journal of the Association for Psychological Science. If a female experimenter patted a participant on the back, they'd risk more money than if she just talked to them, or if a man did the patting. The researchers think this comes from the way that mothers use touch to make their babies feel secure. When we are infants, we receive a lot of touch from our mothers. This creates a sense of attachment, which makes a baby feel secure.

Adult’s Gestures May Prompt Wrong Answers from Children During Critical Interviews
People who interview young children for criminal investigations and other inquiries could elicit false information through their own gestures, particularly if the child is inarticulate, research at the University of Chicago shows. The gestures the children make can also reveal important information that lawyers and police investigators may be missing by not paying attention to hand movements, said Susan Goldin-Meadow, a psychologist at the University of Chicago and an expert on gesture.

Looking Back Key to Moving Forward
New Research from Kellogg School of Management Finds Counterfactual Reflection is Critical to Institutional Prosperity Despite modest economic gains, gloomy unemployment numbers and low workplace morale still loom large within corporate America. Whether or not companies can capitalize on the momentum of this fragile financial revitalization is dependent on more than enhancing consumer confidence or introducing new products to the marketplace—it falls largely on employees working for organizations and their level of commitment to corporate success.
