Contagious yawning is a phenomenon that only occurs in humans and chimpanzees as a response to hearing, seeing, or even thinking about yawning. How many times have you felt the urge to yawn while reading this blog post? Studies have found that certain individuals are more susceptible to contagious yawning than others.
Spontaneous yawning typically occurs when someone is tired or bored. Spontaneous yawning is first observed in the womb, while contagious yawning doesn’t begin until early childhood. The Duke study aimed to better define how certain factors affect someone’s susceptibility to contagious yawning.

Previous studies have suggested that there is a connection between contagious yawning and empathy. However, researchers at The Duke Center for Human Genome Variation found that contagious yawning may decrease as people age and may not be associated with empathy. The study entitled “Individual Variation in Contagious Yawning Susceptibility Is Highly Stable and Largely Unexplained by Empathy or Other Known Factors,” was published March 14 in the journal PLOS ONE. This is one of the most comprehensive studies to examine the factors that influence contagious yawning to date.
