According to a small new study published in the journal Personality and Individual Differences, people with psychopathic qualities may be less likely to yawn when they see someone else do so.
In the study, 135 college students completed a Psychopathic Personality Inventory, or PPI-Revised, which tests for certain psychopathic traits. But while the two behavioral aspects of psychopathy,“fearless dominance” and “impulsive antisociality”, were not associated with yawning, the researchers did see a link between the emotional aspect, or“coldheartedness”, and yawners.
