      abstract     = {Humans often benefit from social cues when learning about
                      the world. For instance, learning about threats from others
                      can save the individual from dangerous first-hand
                      experiences. Familiarity is believed to increase the
                      effectiveness of social learning, but it is not clear
                      whether it plays a role in learning about threats. Using
                      functional magnetic resonance imaging, we undertook a
                      naturalistic approach and investigated whether there was a
                      difference between observational fear learning from friends
                      and strangers. Participants (observers) witnessed either
                      their friends or strangers (demonstrators) receiving
                      aversive (shock) stimuli paired with colored squares
                      (observational learning stage). Subsequently, participants
                      watched the same squares, but without receiving any shocks
                      (direct-expression stage). We observed a similar pattern of
                      brain activity in both groups of observers. Regions related
                      to threat responses (amygdala, anterior insula, anterior
                      cingulate cortex) and social perception (fusiform gyrus,
                      posterior superior temporal sulcus) were activated during
                      the observational phase, possibly reflecting the emotional
                      contagion process. The anterior insula and anterior
                      cingulate cortex were also activated during the subsequent
                      stage, indicating the expression of learned threat. Because
                      there were no differences between participants observing
                      friends and strangers, we argue that social threat learning
                      is independent of the level of familiarity with the
                      demonstrator.},
