      abstract     = {Psychopathic personality traits such as callousness,
                      manipulativeness, and lack of empathy are continuously
                      distributed in non-institutionalized populations. Here, we
                      show that brain responses to emotional movies in healthy
                      females vary as a function of primary (PP) and secondary
                      psychopathy (SP) traits. Healthy female volunteers (n=50)
                      with variable scorings in Levenson Self-Report Psychopathy
                      Scale watched a set of emotional movie clips (n=39) during
                      functional magnetic resonance imaging of brain activity. We
                      found that participants low on primary and secondary
                      psychopathy traits showed higher cortical and subcortical
                      activity when watching emotional movies, what possibly
                      indicates the somatosensory simulation and empathizing with
                      the emotions of movie characters. On the other hand, the
                      individuals with high primary and secondary psychopathy
                      traits presented a lack of vicarious engagement during
                      watching movies and they manifested brainstem-based
                      heightened response towards thread-related stimuli, which
                      could indicate potent autonomic reactivity. Overall, our
                      results indicate that variability in psychopathic traits in
                      the general population is manifested as differential neural
                      responses to emotional signals, and confirm previous
                      findings of there being separate PP and SP personality
                      characteristics due to the dissociable brain activity
                      patterns while viewing emotional movies.},
