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.

人隨著年齡增長,比較不會因為別人打呵欠,自己也跟著打,一份研究發現。

正如先前認為的,傳染性的呵欠與一個人年齡的關係,要比與他們移情能力的關連性來得密切,美國科學家說。研究也顯示,與年齡的關連要比與他們的疲累程度或精力程度來得強烈。

研究人員現在觀察,從他人那裡傳染打呵欠的能力,是不是遺傳而來,希望有助於治療心理健康疾病。

研究人員說,有自閉症與精神分裂症者據說較不容易被傳染打呵欠,因此了解可能影響傳染性打呵欠的基因,或許能闡明新的治療方案。

在這份研究中,三百二十八名參與者觀看播放其他人打呵欠的三分鐘影帶。每個人都必須在他們打呵欠時按一下按鈕。

整體而言,六成八參與者會打呵欠,其中八成二年齡在二十五歲以下,六成年齡在二十五到四十九歲之間,四成一是五十歲以上
