People are less likely to yawn when others do as they get older, a study has found.
Contagious yawning is linked more closely to a person’s age than their ability to empathize, as previously thought, US-based scientists said. It also showed a stronger link to age than tiredness or energy levels.
Researchers are now looking at whether the ability to catch yawns from other people is inherited, with the hope of helping treat mental health disorders.
Autism and schizophrenia sufferers are reportedly less able to catch yawns, researchers said, so understanding the genes that might code for contagious yawning could illuminate new pathways for treatment.
In the study, 328 participants were shown a three-minute video showing other people yawning. Each subject had to click a button every time they yawned.
Overall, 68 percent of the participants yawned. Of those, 82 percent of people aged under 25 yawned, compared with 60 percent of people aged between 25 and 49, and 41 percent of people aged over 50.
