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.

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.

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.
