An important task in social cognition is understanding what another person is paying attention to. Accurately perceiving the attention, intention, and beliefs of another person, so-called “theory of mind,” underpins fluent social functioning and high social-emotional intelligence. The “mind beam” hypothesis of social attention, which has been supported by non-invasive functional magnetic resonance imaging (fMRI) experiments, posits that the brain models the attention of others as an implied motion, or “mind beam,” connecting agents to attended objects.
