K0g*|N|.x |0When you’re sick, it’s written all over your face. That’s the conclusion of a new study in the Proceedings of the Royal Society B, which finds that sick people share facial features—pale skin, swollen faces, droopy eyelids, and looking tired—that reveal they might be contagious.心理学空间p.E#@(P7e.|~M

Researchers took mug shots of 16 Caucasian volunteers a few hours after injecting them with a placebo or a piece of bacteria that made people feel sick and caused their immune systems to respond as if they had an infection.

They then showed the photos to 62 people, who rated the faces (pictured above as composite images with noninfected individuals on the left and infected on the right) as “sick” or “healthy” in 5 seconds or less.心理学空间8dtY5e z

然后他们让62个人评论这些人的照片人,让他们在5秒内对照片中的脸部进行评估,看看那张面孔(在上面的复合图像中,左侧是未受感染的,右侧是受到感染的)是“生病的”或“健康的”。心理学空间*J~i!qV9G#c.B C%x A

Raters identified 81% of sick people better than chance. But, what is it about our faces that give away whether we’re feeling under the weather? To find this out, a separate group of 60 people assessed how sick and tired the people in the photos looked and the extent to which each trait—pale skin and lips, droopy eyelids and corners of the mouth, how puffy their faces looked, eye redness, and tiredness—publicized illness.
