You could be a psychopath if you don’t yawn: Scientists reveal that people with low empathy levels don’t copy the gestures of others

  • Researchers from Baylor University tested students for anti-social traits
  • Those who scored highly on ‘cold-heartedness’ were less likely to yawn when shown video clips of facial expressions
