U. VIRGINIA (US) — We are hardwired to feel empathy because we closely associate people who are dear to us—friends, spouses, lovers—with our very selves, brain scans show.
“With familiarity, other people become part of ourselves,” says James Coan, University of Virginia psychology professor who used functional magnetic resonance imaging brain scans to find that people closely correlate people to whom they are attached to themselves. The study appears in Social Cognitive and Affective Neuroscience.
“Our self comes to include the people we feel close to,” Coan says. In other words, our self-identity is largely based on whom we know and empathize with.
Coan and his colleagues conducted the study with 22 young adult participants who underwent fMRI scans of their brains during experiments to monitor brain activity while under threat of receiving mild electrical shocks to himself or herself, or to a friend or stranger.
The researchers found, as they expected, that regions of the brain responsible for threat response—the anterior insula, putamen, and supramarginal gyrus—became active under threat of shock to the self.
In the case of threat of shock to a stranger, the brain in those regions displayed little activity. However when the threat of shock was to a friend, the brain activity of the participant became essentially identical to the activity displayed under threat to the self.
“The correlation between self and friend was remarkably similar,” Coan says. “The finding shows the brain’s remarkable capacity to model self to others; that people close to us become a part of ourselves, and that is not just metaphor or poetry, it’s very real. Literally we are under threat when a friend is under threat. But not so when a stranger is under threat.”
Coan says this likely is because humans need to have friends and allies who they can side with and see as being the same as them. And as people spend more time together, they become more similar.
“It’s essentially a breakdown of self and other; our self comes to include the people we become close to,” Coan says. “If a friend is under threat, it becomes the same as if we ourselves are under threat. We can understand the pain or difficulty they may be going through in the same way we understand our own pain.”
This likely is the source of empathy, and part of the evolutionary process, Coan reasons.
“A threat to ourselves is a threat to our resources,” he says. “Threats can take things away from us. But when we develop friendships, people we can trust and rely on who in essence become we, then our resources are expanded, we gain. Your goal becomes my goal. It’s a part of our survivability.”
People need friends, Coan added, like “one hand needs another to clap.”
