According to new research, people with psychopathic personality traits, such as remorselessness, are less likely to yawn after seeing another person yawn.
Contagious yawning is well-documented in humans, and previous studies have shown that empathy is linked to susceptibility to contagious yawning. Its characterized by callous and dominant behavior as well as deficiencies in empathy, which may cause those with psychopathic traits to be less susceptible to contagious yawning.
There has been a growing interest in understanding the factors that influence the yawn contagion. However, previous psychological studies examining individual differences in the contagiousness of yawning have produced mixed results, according to Andrew C. Gallup, an associate professor of psychology at the State University of New York Polytechnic Institute.
Many of these studies have been conducted on relatively small and homogenous samples. Currently, the majority of the research was undertaken on contagious yawning, suggesting a negative relationship.
In the latest study, 458 participants from 50 different countries watched a three-minute video depicting 49 yawns from humans and one yawn from a dog. Afterward, they were asked to indicate whether they had yawned while watching the video. Several tests of psychopathic abilities were then completed.
In response to the video, approximately 63% of participants reported yawning contagiously. These findings suggest that individuals who reported yawning did not score on the psychopathy tests as much as those who did not.
People who score higher on psychopathic personality traits tend to be less likely to yawn contagiously, according to Gallup. These findings are consistent with previous findings suggesting that psychopathy is linked to a generalized impairment in behavioral contagion and biobehavioral synchrony. Additionally, our findings suggest that participant fatigue/tiredness increase yawn contagion.
However, the findings were held even after the researchers calculated for gender, age, prior sleep the previous night, self-reported fatigue, and objective and subjective levels of attention to the video. Despite this, this research, however, has included some guidelines. Despite this, the reliance on self-reported statistics and the lack of ability to monitor participant attention to the contagious yawning stimulus were the most significant limitations.
The new findings are based on a previous investigation, which used facial electromyography and galvanic skin response as objective measures of yawn contagion.
According to one research, the greatest predictor of contagious yawning was actually self-reported tiredness. In this regard, we should not immediately write someone of as a psychopath when he or she does not yawn in response to seeing someone else, according to Jorg J. Massen''s co-author. He or she may just be unwell.
People who score higher on psychopathic traits are less likely to jump contagiously, according to Andrew C. Gallup, Mariska E. Kret, Omar Tonsi Eldakar, Julia Folz, and Jorg J. M. Massen.
