This suggests that perhaps in more adversarial situations, like during an argument, eye contact might be associated with dominance or intimidation, rather than a sign of connection as it might be in friendly situations. The researchers note that given that different cultures vary in how they use eye contact, the results might not be applicable on a worldwide scale. Plus, it's pretty creepy to stare directly into someone's eyes for the entire time they talk to you, so this might not replicate real-world interactions precisely. Next, the researchers plan to study whether there are physiological changes associated with eye contact that may be at play, like an increase in heart rate or release of stress hormones. "Eye contact is so primal that we think it probably goes along with a whole suite of subconscious physiological changes," lead author Frances Chen said.
