When someone smiles at you, you mig

When someone smiles at you, you might smile back, sometimes without even realizing it.
It turns out that not just our smiles, but all of our 41 expressions could spread from one person to another, according to a paper recently published in a magazine.
“We tend to mimic (模仿）the smiles of others 42 it helps us better understand what other people are feeling, _43us to respond accordingly.” explained Adrienne Wood, the lead author of the 44 .
In addition, researchers found that a model in the brain might be the 45 of the mimicry. The model shows that when people 46 a certain expression, be it happy or sad, they instantly “try it out”. In doing so, their brains find the 47- memories of the same expressions being made and remind them of their feelings then. In this way, they can act in the 48 way to others according to their own 49 reaction. But Wood noted that this 50 happens “below your awareness” and “within a few hundred milliseconds (毫秒).”
Sometimes the brain recreates the 51 without the facial muscles actually making it. 52，rather than giving a full smile, sometimes we only turn up the comers of our 53 Despite this, our under­standing of others’ emotions isn’ t reduced.

“Facial mimicry certainly plays some role, and perhaps a key role, in 58 other people’s emotional states,” said Kevin Ochsner from Columbia University. However, he also 59 that facial expressions may sometimes not give clear clues, so facial mimicry may not be 60 to fully understand the emotional state of a person in every condition.
