A new study conducted in United States revealed surprising results. As per the new findings, persons with psychopathic traits are less likely to fall prey to the contagious yawning.
While the usual characteristics are self centeredness, manipulative, impulsive and heartless behaviors, the researchers at the Baylor University explained that these individuals are stronger not to fall vulnerable to social yawning.
Interestingly, contagious yawning is associated with patterns of emotion and sympathy. The study included 135 college going students, who were exposed to a lengthy psychological examination.
Brian Rundle, a doctoral student and lead researcher in psychology and neuroscience at Baylor University in Waco, Texas, pointed out in the news release that the test doesn’t tell specifically whether or not someone is a psychopath.
