Link Between Female Psychopaths and Head Movement

A new study suggests that a woman's head movement during a conversation could be a giveaway of psychopathy, with psychopaths tending to keep their heads very still. The study used head tracking algorithms to analyze recordings of women being interviewed by police. This is the first study linking female psychopaths and nonverbal communication. Psychopathic women displayed more stationary head positioning during interviews, similar to psychopathic men. The study used the 'Hare Psychopathy Checklist - Revised' to assess psychopathy levels.
