You open your eyes and mouth wide if you see a live rat in your bedroom but you wrinkle your nose and narrow your eyes if you see a dead one in the road. Why is that? Facial　 expressions are usually thought of as simple tools of communication. But in his book The Expression of the Emotions in Man and Animals, Charles Darwin proposed that they may prepare us to react to different situations when he noticed that some expressions seemed to be used across cultures and even species. Now Joshua Susskind and his colleagues at the University of Toronto, Canada, have put that idea to the test.

Susskind’s team wondered whether the expressions of fear might improve how sensory (感官的) information is acquired and so sharpen senses. Conversely disgust (厌恶) might weaken the senses, sheltering us from unpleasant sights and smells.

The researchers asked volunteers to complete various tests while holding a fearful, disgusted or neutral expression. In one test, they had to identify when a spot entered their sight. In another they were required to shift their focus as quickly as possible between two targets on a computer screen. It was also measured how much air the volunteers breathed in while expressing fear and disgust.

In each case the wide-eyed faces let significantly more of the world in. Volunteers with wide-open eyes detected surrounding objects more quickly and performed side-to-side eye movements faster. They also took in more air with each breath without any extra effort. An MRI (核磁共振) scan showed the nasal cavity (鼻腔) was enlarged while volunteers held this expression, which could be linked with a greater ability to absorb smells.

“These changes confer the idea that fear, for example, is a posture towards sensory sharpening while disgust a posture towards sensory rejection,” says Susskind. His team is already at work on experiments to explore to what extent the brain can use this extra information to enhance performance.
