An article by Keith Oatley, in Scientific American/Mind, asserts a connection between exposure to fiction and the development of empathy. It’s not a new idea–IIRC, the idea that seeing plays and reading novels has tended to increase empathy throughout entire societies has been asserted by Harold Bloom, among others–but Oatley describes empirical research he’s done to test this assertion.
In one experiment, Oatley and colleagues assessed the reading habits of 94 adults, separating fiction from nonfiction. They also tested the subjects on measures of emotion perception (being able to discern a person’s emotional state from a photo of only the eyes) and social cognition (being able to draw conclusions about the relationships among people based on video clips.) This study showed a “strong” interconnection between fiction reading and social skills, especially between fiction reading and the emotion-perception factor. This correlation, of course, does not by itself demonstrate the direction of causality.
Another study involved assigning 303 adults to read either a short story or an essay from the New Yorker and following up with tests of analytical and social reasoning. Those who read the story tended to do better on the social reasoning test than those who read the nonfiction essay.
Oatley argues that “Good social skills require having a well-developed theory of mind…the ability to take the perspectives of other people, to make mental models of others, and to understand that someone else might have beliefs and intentions that are different from your own.” He says that children start to acquire this ability at about 4 years old, and that “the ability to gauge emotion from pictures of just the eyes correlates with theory-of-mind skills, as does the capacity for empathy.”
