Eating Disorders
The Extreme Female Brain

Dario Maestripieri Ph.D. on August 23, 2012

Men are better at “systemizing”, which involves carefully analyzing information and categorizing it in relation to some principles, while women are better at “empathizing”, which involves understanding and caring about other people’s feelings. Too much empathizing, however, may lead to fear of negative evaluations and contribute to the occurrence of eating disorders.

I have seen congested traffic and aggressive drivers in many cities around the world. More than once I have noticed that if two cars arrive simultaneously at an intersection, one driver will honk his horn and try to engage the intersection before the other does.

The Seven Year Itch: Theories of Marriage, Divorce, and Love

Dario Maestripieri Ph.D. on February 3, 2012

In the 1955 film The Seven Year Itch, a married man struggles with the temptation to leave his wife and small child to run off with the young woman next door, played by Marilyn Monroe. The title of the film refers to a time in a marriage when—according to the U.S. Census Bureau—a divorce is most likely to happen.

Relationships
Is Love Meant to Be Stressful?

Dario Maestripieri Ph.D. on January 29, 2012

All cooperative relationships share the same commitment problem: a business partner may cooperate one moment and cheat in another; a Congressman may support Romney's campaign for months and then switch allegiance to Gingrich the day after he wins the South Carolina Primary. The commitment problem occurs because costs and benefits of a relationship may change over time.
