Contagious yawning is believed to be driven by empathy, a trait that psychopaths often lack. In addition, research points to other physical signs that may reveal that you are dealing with a psychopath. Next, let's explore two of these signs!
Studies indicate a new trait of psychopathy
In a 2015 study conducted by Baylor University in Texas, 135 students were analyzed for characteristics such as Machiavellian self-centeredness and emotional coldness.
During the research, participants were exposed to video clips in which people displayed a variety of facial expressions, including yawning. It is well known that the tendency to yawn is contagious, especially in situations of fatigue.
According to the study, participants who scored high on traits of emotional coolness were less likely to be affected by contagious yawning.
Contagious yawning has been widely linked to empathy, suggesting a possible link between the ability to to emotionally relate to others and the tendency to yawn in response to visual yawning stimuli.
In addition to yawning in response to another, psychopaths tend to have a different sleep routine. In a study conducted by Australian researchers in 2013, it was observed that the preference for staying up late or even until dawn is directly associated with antisocial behavior and the characteristic traits of psychopaths.
However, it is important to point out that a lack of response to contagious yawning or a preference for sleeping late does not necessarily indicate that something is wrong with the person. Each individual is unique in their response to social stimuli and, certainly, the help of specialists is necessary for a complete diagnosis.
