From the NYTimes:
...after reading literary fiction, as opposed to popular fiction or serious nonfiction, people performed better on tests measuring empathy, social perception and emotional intelligence — skills that come in especially handy when you are trying to read someone’s body language or gauge what they might be thinking....The researchers, social psychologists at the New School for Social Research in New York City, recruited their subjects through that über-purveyor of reading material, Amazon.com. To find a broader pool of participants than the usual college students, they used Amazon’s Mechanical Turk service, where people sign up to earn money for completing small jobs.
The study is quite interesting:
After reading — or in some cases reading nothing — the participants took computerized tests that measure people’s ability to decode emotions or predict a person’s expectations or beliefs in a particular scenario. In one test, called “Reading the Mind in the Eyes,” subjects did just that: they studied 36 photographs of pairs of eyes and chose which of four adjectives best described the emotion each showed.Is the woman with the smoky eyes aghast or doubtful? Is the man whose gaze has slivered to a squint suspicious or indecisive? Is she interested or irritated, flirtatious or hostile? Is he fantasizing or guilty, dominant or horrified? ...“It’s a really important result,” said Nicholas Humphrey, an evolutionary psychologist who has written extensively about human intelligence, and who was not involved in the research. “That they would have subjects read for three to five minutes and that they would get these results is astonishing.”
After three or four minutes.
I'm thinking fluid mind. The reading revs up the areas and circuits of the brain for social cognition. When the subjects take the test, those brain areas are tuned and ready to go.
