Yawning and Psychopathy

Guest: Brian Rundle, Doctoral Student of Psychology and Neuroscience at Baylor University  Everybody knows yawning is contagious. Now, scientists have figured out the level of contagion in a yawn is tied to a person’s empathy. If you know or care about the yawner, you’re more likely to yawn when you see them doing it.   Conversely, if you are immune to contagious yawning, you just might be lacking on the empathy scale, and that just might mean you have the makings of a psychopath.
