Human faces may hold more meaning for socially outgoing individuals than for their more introverted counterparts, a new study suggests.
The results show the brains of extroverts pay more attention to human faces than do introverts. In fact, introverts' brains didn't seem to distinguish between inanimate objects and human faces.
The findings might partly explain why extroverts are more motivated to seek the company of others than are introverts, or why a particularly shy person might rather hang out with a good book than a group of friends.
"[This] supports the claim that introverts, or their brains, might be indifferent to people — they can take them or leave them, so to speak. The introvert's brain treats interactions with people the same way it treats encounters with other, non-human information, such as inanimate objects for example," Fishman told LiveScience.
